"Hit it like rom-pom-pom-pom! Get it hot like Papa John! Make a bitch go on and on! It's a femininomenon!"

Penny Thompson sat in the waiting room, listening to music on her headphones and singing along under her breath. She was trying to distract herself from the task at hand, to keep from rushing out of the doctor's office and never coming back. She nervously twirled a finger in her mop of frizzy red curls. She wore baggy black sweatpants and a bulky gray hoodie, which served as her traditional teenage Please-Don't-Look-At-Me camouflage.

Penny was 19 years old, about to start her first semester at Plainview College of Arts. She had earned a generous scholarship, which had helped convince her parents to let her pursue an economically questionable degree like Fine Arts. But the college required updated vaccinations and a recent physical examination before she could move into the dorms.

Penny hadn't had a full physical since she hit puberty. Her childhood physician had been a kind elderly man, who specialized in children with her unique condition. She hoped this new doctor would be professional and non-judgmental, but she was scared about letting a new doctor examine her. A full physical was embarrassing for anyone, and Penny had more to worry about than most.

But she wanted desperately to get out of her parent's house. To experience dorm life and take the art classes she was so excited for. If she lost out on this scholarship, she would never get this opportunity again. That meant an updated physical. So... here she was.

The doctor's office was small and private, at the end of a quiet strip mall. Just a simple waiting room with a reception desk, and an open doorway leading into a short hallway with two doors facing each other at the end. Penny had made an appointment for late in the day, so she was the only patient there. A phone rang, and the receptionist picked it up.

"Dr. Fellows' office, this is Mrs. Hamada speaking," the middle aged Asian woman answered with a hint of boredom. "Are you calling for a general medical appointment, or for a sex therapy appointment?"

Penny's perpetually horny, 19-year-old brain perked up at the word "sex," and she shifted one of her headphone cups off of one ear to eavesdrop.

"Oh yes, that's a problem that Dr. Fellows specializes in," The receptionist said to the caller. "She's successfully helped many couples and individuals... though results are never guaranteed." Did Penny detect a trace of sadness in Mrs. Hamada's voice?

Penny soon lost interest as the receptionist moved on to confirm some boring appointment details and insurance logistics. When the receptionist finished with the call, she stood up from her desk, took a clipboard of notes off the wall, and told Penny to come with her.

Penny followed behind, trying not to stare at the receptionist's ample backside that swayed as she walked, or her thick calves that peeked out from her sensible black pleated skirt. Mrs. Hamada's open toed sandals clicked softly as she walked. Penny's white tennis shoes squeaked on the marble floor.

The receptionist led Penny down the hallway. The door to the left had a placard reading "Therapy," the door to the right had a placard reading "Exam." The receptionist opened the door to the exam room and motioned Penny to enter.

It was a fairly standard examination room. There was a small desk and computer against one wall, with a swivel chair tucked underneath it. A big metal exam table took up most of the room, with a thin plastic cushion on top. Along another wall was a sink, a cabinet for supplies, and a small metal locker. The opposite wall held a full length mirror.

"Here we are, Miss Thompson! Go ahead and get undressed, you can put your clothes in that locker for safe keeping. Here's a hospital gown for you to wear." She pointed to a blue cloth gown folded neatly on the examination table. "Then have a seat and relax, Dr. Fellows will be with you shortly." The receptionist put the clipboard of notes on the desk, left the room, and closed the door behind her.

Penny took off her headphones, then her sneakers and socks, and put them on the bottom of the locker. Then she peeled off her sweatpants, revealing her tight little bottom covered in white cotton boy shorts. Next she pulled off her hoodie, leaving a simple white bra covering her chest.

Penny looked at herself in the mirror. She was tall and thin. A kind person might call her coltish; a cruel person might call her lanky.

She wasn't entirely devoid of curves, to be fair. Her butt had a nice compact roundness to it, her legs and arms were long and lean, and her waist was narrow and graceful. Her skin was pale milky white, but covered with a speckling of freckles, especially on her face, shoulders, chest and forearms.

Her mop of frizzy red curls complimented her angular but feminine facial features. She was a little self-conscious about her ears, which stuck out from her head and were impossible to hide with her hair, except when she wore her headphones. But her ears weren't what was bothering her.

Penny took a deep breath to calm her nerves, then unhooked her bra, exposing perky, freckled breasts. The cold air of the exam room made her shiver, and caused her little pink nipples to grow erect, standing out from her puffy pale areolas. Then she took off her white cotton boy shorts, quickly slipped into the blue hospital gown, laced it up as well as she could manage, and sat on the examination table. Her hands went unconsciously to her lap, covering her private parts.

Penny Thompson wasn't like most girls. She had been born with both a vagina and a penis. Her childhood doctor had pronounced her to be perfectly healthy, and that she did not require any supplemental hormones or corrective surgery. Her parents didn't want to subject their child to unnecessary surgeries just to make her what society would deem "normal," so they let her develop naturally.

Her uncircumcised penis was usually very small and soft, easily concealed in the tight boy short underwear that she preferred. But it grew quickly when Penny was aroused, and was rock hard when erect. Below the root of her penis where a pair of testicles would be on a male, she had a petite, tight little vagina. Penny kept both parts hairless, except for a small patch of curly red pubic hair above the base of her penis.

She tried to relax, but fidgeted nervously. The cold rubber of the examination table was causing blood to rush to her nether regions, and her cock was becoming slightly engorged. "You need to chill out, Nine!" Penny hissed at her cock. She had given it the nickname when she started watching porn as a teenager, and realized that she was bigger than most male porn stars. Self conscious about her body as she was, she did take some silent pride in that.

There was a firm knock on the door, then the doctor walked into the room. "Hello, Penny. My name is Dr. Grace Fellows. You can call me Dr. Grace."

Dr. Grace was a mature woman of 50, with close cropped platinum hair. Her body was athletic and fit, from years of regular swimming. Her breasts were large and pendulous, but had resisted gravity admirably and stood out proudly. Her legs and backside were shapely and muscular. She had some crows feet in the corners of her eyes and laugh lines around her mouth, but she was still a very handsome woman, and clearly took care of herself.

In the clinic she wore a long white doctor's coat that reached down her knees. Under it she wore a gray silk blouse, buttoned up high, and a snug black pencil skirt that came down to her knees. She had a pair of black rimmed, rectangular glasses on the bridge of her nose, with a gold chain that could hold them around her neck when not needed.

Dr. Grace took the clipboard containing Penny's patient notes off of the desk. She pulled the swivel chair out from under the desk, sat down and wheeled it closer to the examination table, crossing her legs. Her skirt rode up slightly, revealing a glimpse of her bare white thighs where her dark stockings ended. Penny gulped.

"Alright, Penny. I have your medical records here, but I like to confirm everything verbally when I take on a new patient. How old are you?"

"Um, 19 years old." Penny replied.

"Reason for a physical?"

"I'm beginning college, and they require updated immunizations and a full physical before I can move into the dorms. It's um... been a few years since my last exam," Penny said nervously.

"Well, it's not uncommon for young people to stop getting regular check-ups after they hit puberty. But trust me, it's better to stay in the habit and maintain a health record!"

Dr. Grace flipped through the sparse pages she had on Penny. Her eyes widened as she read an intake note.

"It says here that you have an 'indeterminate intersex condition.' That's fascinating, Penny!"

The young woman nodded silently. "Here it comes," She thought to herself with dread.

The doctor leaned in. "There are a whole spectrum of intersex variations, and they present in different ways developmentally. Chromosomal differences, sensitivity or insensitivity to different hormones, chimerism, mosaicism... it seems you were tested for known variations as a child, and none were confirmed. So, what is the presentation of your genitals?"

Penny blushed and stuttered. "Um... w- what do you mean?"

"Well, in the past doctors would recommend surgery shortly after birth, to conform to one sex or the other. Fortunately that's less common today, better to give the child some autonomy and choice in anything that could permanently alter their body. I realize talking about this might be embarrassing, but knowing your details will help me complete your physical and take care of you as my patient."

Penny nodded slowly. "Well, I have... b- both a vagina and a penis. I think everything is... um... fully developed."

"Your vagina is fully functional? What about your ovaries and uterus? Do you have a regular menstrual cycle?"

"Y- yes, I think everything there is fully functional... my last period was a week ago."

Dr. Grace made a note on Penny's chart. "And your penis, it's functional as well? Do you ever experience erections? Ejaculation?"

Penny blushed even harder, her freckled neck and upper chest turning bright red. "Y- yes, Doctor, both. F- frequently."

Dr. Grace raised her eyebrows curiously, and jotted down another note. "Fascinating! And are you sexually active?"

Penny stammered, "I... am I... active?"

Dr. Grace smiled knowingly, and said "Of course, nearly all people your age are sexually active... with themselves. It's natural and healthy to explore your own body and learn how to pleasure yourself. What I mean is, have you had any sexual contact with other people? Any sexual partners?"

"Uhh... No, no p- partners." Penny stuttered, her cheeks burning.

The doctor nodded kindly. "Ok. Now, Penny, I'm going to give you a full physical examination. If you have any questions along the way, please don't hesitate to ask. If you're uncomfortable at any time, you can ask me to stop and I will do so immediately."

Penny nodded. Dr. Grace turned to grab a pair of blue latex gloves, which she put on with a snap.

"First we're going to record your height and weight. Please hop off the table and stand on the scale." Penny stood up and walked to the scale, trying to keep her gown closed with one hand. Dr. Grace wrote down her weight, and told her to move to the height measuring tool on the wall.

"Stand up straight please, heels against the wall." Penny did as she was told, straightening her posture and causing her hard nipples to poke against the fabric of her gown. The doctor moved the little marker on the wall down to the crown of her head, and took a measurement.

"6 feet 2 inches, very tall for a woman! You're a healthy weight for your size and you have an excellent physique, very statuesque." Dr. Grace said as she wrote down her measurements.

Penny giggled girlishly, not used to receiving praise like that, especially from an attractive older woman. Her cock jumped slightly at the compliment, creating a small but noticeable tent in the front of her gown. She glanced down at it in alarm, but there was nothing she could do to stop it.

Dr. Grace couldn't help but notice the bulge, but maintained her professionalism and didn't let her gaze linger.

"Alright, hop back on the exam table. Please unlace the back of your gown, so I can check your spine and listen to your lungs." Penny sat down, undid the top lace of the hospital gown, and exposed her pale, freckled back. Dr. Grace took a stethoscope out of its drawer and placed it between Penny's shoulder blades. "Deep breath, please."

"Very good. Now I need you to let the gown down to your waist. I'm going to listen to your heart, and then I'm going to do a breast examination."

Penny did as instructed, leaving the thin cloth gown bunched in her lap. Dr. Grace placed the stethoscope between Penny's small perky breasts, listening to her heartbeat. Penny felt like it was going to beat entirely out of her chest, but the doctor seemed satisfied.

Dr. Grace took Penny's left breast in her gloved hand, squeezing it gently but firmly to check for lumps. Then she pinched and rolled Penny's nipple, making it stand up even harder than it already was. Penny's breathing quickened.

The doctor then moved on to Penny's right breast, first kneading it gently, then pinching and rolling the nipple until it stood erect. A small involuntary moan escaped from Penny's lips. "Oh gosh, sorry..." She mumbled.

Dr. Grace pretended not to notice. She finished her breast exam, then helped Penny pull her gown back up over her chest. She tried not to look at the increasingly obvious bulge in Penny's gown, but it was hard to ignore.

"Alright, now for the embarrassing parts," Dr. Grace said with a wink, trying to diffuse the awkwardness. She slid two metal stirrups out from the exam table. "I need you to lay back on the table, put your legs in the stirrups, and then pull the gown up just enough so that I can see your vagina. I'm going to do a genital examination, but I promise this won't hurt a bit."

Penny gulped, then laid back and put her legs up. As she pulled the gown up her thighs, until her small, hairless vagina was exposed. The base of her penis was still covered by the gown, and she held her bulge down with her hands.

Dr. Grace squired a little dollop of lubricant on two of her fingers, then gently spread Penny's labia. "Your hymen is not intact, but that's perfectly normal for a physically active young woman It's not a reliable indicator of virginity, like some people think."

She slowly inserted her index and middle fingers into Penny's vagina, being careful not to hurt her. Penny gasped, but held still. "Your vaginal canal is tight, but it seems to be within a normal size range. Lubrication is normal," She said as she gently pulled her fingers out of the girl's sex. The tips of her gloved fingers glistened with slick feminine moisture.

The doctor lightly grazed Penny's small clitoris with her thumb, making her squeak in surprise and arousal. Dr. Grace smiled at the girl laying spread eagle on the table before her. "Everything seems perfectly healthy. You have a beautiful vagina, Penny."

"Now I'll need you to pull your gown up to your bellybutton. I need to examine your penis as well. Please don't be embarrassed if you've got an erection, dear. It's perfectly natural, and I've seen plenty in my line of work," Dr. Grace smiled reassuringly.

Penny took a deep breath, and slowly pulled the thin gown up past her waist. Her cock sprang to attention, fully erect. A tiny drop of precum glistened at the tip, and faintly blue veins visibly pulsed beneath Penny's pale skin.

Dr. Grace's eyes widened. "Oh my god!" the older woman exclaimed, heat rising in her chest and face. She cleared her throat, surprised by her own outburst. "Sorry, it's just... a lot larger than I expected. You've got one of the biggest co-- err, penises, I've ever seen, Penny. Have you... measured it?"

Penny stuttered, "Y- yes, Dr. Grace... L- last time I checked, it was nine inches long when it's... F- fully hard." The girl was clearly embarrassed, but her voice betrayed a hint of pride.

"Nine inches! That's much larger than the average adult male." Dr. Grace continued, struggling to maintain her professional composure. She wrote "9 inches(!)" on her notes, and then underlined it for effect.

She gently grasped the base of Penny's straining cock with a gloved hand. The bead of precum rolled down the length of Penny's shaft, and pooled in the curve between her thumb and index finger.

The doctor's soft touch sent a wave of pleasure through Penny's body, and her cock pulsed, sending another glistening stream of precum down her shaft.

"I'm going to gently squeeze the base to check for any irregularities." Dr. Grace said, her voice husky and strained. Penny nodded, trying to control her rapid breathing. "No external testicles, but copious amounts of Cowper's fluid... if you can ejaculate as you say, then you must have internal, undescended testicles. I wonder if you have fertile sperm as well," the doctor mused to herself, professional curiosity fighting with her growing arousal.

The doctor's hand slowly made its way up the length of Penny's cock, becoming slick with the precum now steadily flowing from Penny's urethra. Dr. Grace's thumb grazed the edge of the glans, causing Penny to gasp and buck her hips.

"Oh gosh, Dr. Grace, I..." Penny moaned.

Unthinkingly, instinctively, the older woman continued to stroke the girl's cock, her breathing becoming faster. Penny whimpered and shuddered, in shock but unable to speak, unwilling to stop what was happening. Her hips bucked up and down, grinding her cock into Dr. Grace's palm. Dr. Grace did not let go, her tightening grip moving up and down the girl's slippery length with increasing urgency.

Penny's hands grasped the examination table's edge, her knuckles white. "Dr. Grace! Oh my gosh..." she whimpered.

A massive jet of cum spurted from Penny's slit, arcing through the air and striking Dr. Grace square in the glasses, face and chest. The older woman gasped and pulled back, releasing Penny's pulsing cock. Penny's hips bucked again and again, spraying thick ropes of cum all over her stomach and thighs. Her pussy pulsed in time with her cock, squirting a small puddle of feminine fluids onto the table under her tight little butt.

When Penny's orgasm finally subsided, she was mortified. "Oh my gosh, I'm s-so sorry!" She wailed, unsure of what to do.

Dr. Grace snapped out of her reverie, and registered what had happened. She had just jerked off a 19-year-old patient! Without thinking, she licked her lips and tasted Penny's salty-sweet cum.

The older woman looked down at herself. Her blouse was painted with several thick, pearly ropes. She realized that her pussy was sopping wet, and she had soaked through her panties. She hadn't been this aroused in years, and felt herself on the verge of her own orgasm even though her body hadn't been touched in any way.

The two women stared at each other in shock, neither able to break the silence.

Dr. Grace licked her lips again, still slick with cum. Without a word, she reached both her hands down her pencil skirt and into her black silk panties. She began to rub her aching clit with one gloved, cum covered hand, while plunging two fingers of her other hand into her cunt. For about thirty excruciating seconds she masturbated furiously, her eyes glazed and unfocussed, until a powerful orgasm crashed into her. "Oh fuck... Penny!" She cried out, grunting deeply through her orgasmic contractions. Her legs tensed, her toes curled, her pussy clamped tightly around her fingers as she came.

Penny stared, mouth agape, watching in shock as the older woman climaxed for what seemed like several minutes.

Dr. Grace finally came to her senses and sat up in the chair. "What the hell... just happened?" Dr. Grace gasped, wiping the remaining cum off her face. "How did you just... oh my god... I haven't had an orgasm like that in thirty years... You didn't even touch me!" She reached for a tissue to clean the pearlescent string of cum from her glasses.

"I'm so sorry, Doctor!" Penny said, tears welling up in her eyes. "I just couldn't control it... I should have said something..."

Dr. Grace held up her hand and said, "Penny, please, I... I'm sorry too. I don't know what came over me. That was completely unprofessional, I should never have done that to you."

The doctor took several deep breaths and composed herself. She went to the supply closet in the corner of the room for a washcloth, wet it with warm water from the sink, and turned to hand it to Penny. "Well, let's get you cleaned up, and then I'm going to need... to..." She trailed off as she looked at Penny's cock. It was still rock hard, rising proudly above her pussy and straining up past her belly button.

Dr. Grace stood in her tracks, staring at the young redhead, her lithe freckled body, and her erect nine-inch cock. She licked her lips again, subconsciously hoping for another taste of cum. She locked eyes with the young woman. "Penny... If you'd like to be done here, I'll end our appointment right now, give you a clean bill of health, and I won't charge you anything after our... incident. But if you're not too upset with me, and you're willing, I'd like to try something... a little unorthodox."

Penny held the older woman's gaze, and felt a flutter in her chest. "Umm... W- what did you h- have in mind?" She was frozen in place like a deer in the headlights, and made no move to get dressed.

The doctor smiled, and began casually unbuttoning her cum-soaked blouse. "You see Penny, along with my standard medical practice, I'm also a sex therapist. I help people who struggle with sexual problems. Couples who are no longer intimate; men who have problems with premature ejaculation or stamina; and women who have trouble reaching climax... like myself."

She shrugged off her silk blouse to reveal a lacey black bra. Her torpedo tits jiggled enticingly as they emerged from their confines.

"Most women -- four out of five -- rarely have an orgasm from vaginal penetration alone. But some have trouble reaching climax with clitoral stimulation as well, even with vibrators or toys. I find it extremely difficult to achieve an orgasm, with or without a partner. It can be quite frustrating, which is why I began to specialize in that field on the side, hoping to help others as well as myself."

The doctor slipped her bra off, and the soft mounds of her breasts were revealed in all their glory. Her thick, dark nipples stood proudly, surrounded by large dark areolas.

"But I just had one of the best orgasms of my life, and I barely even touched myself. There's something special about you. I don't know if it's a pheromone in your semen that caused me to react that way, or just your natural sexuality. But your body, your scent, your... remarkable cock... I'd like you to fuck me."

The doctor unzipped the back of her skirt and let it fall to the floor. She slid down her soaking wet panties, and stood up to reveal her toned, mature body. She kept her black stockings on, which went up to her mid thigh and created gentle indentations in her ample flesh. Her vagina was covered in a trimmed patch of light brown pubic hair. Her pussy lips were swollen and parted with desire, and her prominent clit was pulsing visibly.

"Now, I know that you're a virgin, and I'm your doctor. Normally this would be a huge breach of medical ethics. But you're not a normal girl. I think you would benefit from an experienced partner for your first time... and I think I would benefit from your special gift."

Penny gasped, eyes wide with confusion and desire. She nodded her head slowly, opened and closed her mouth, then realized no words had come out. She cleared her throat and said, "Oh gosh... I... I guess I would l- like that, Dr. Grace."

The doctor grinned and said, "Follow me, then."

Dr. Grace took Penny's hand and led her out of the examination room, both of them naked, dashing across the short hallway and into her private office. Penny's cock bounced as she followed the doctor, gazing at the older woman's toned ass, legs and back.

The walls of the private office were painted a calming pastel, and the lights were dimmed. There was a dark oak desk with a computer and phone, a couple of cozy looking lounge chairs, and a King-sized bed in one corner, covered with a red satin sheet and piled with pillows. Near the bed was another door, leading to a small bathroom with a shower. "This is where I conduct my sex therapy practice, much more comfortable and intimate than the cold sterile exam room. Much of the work is consultation and talk therapy, but some of it is... more intimate."

The doctor laid down on the bed, her muscular ass on the edge of the mattress, elbows propped up so she could look at the tall young ginger and her enormous cock. She smiled invitingly, and motioned Penny to approach. "Don't worry about technique or foreplay or stamina right now, dear. You can practice those things later. Just take it slow, do what comes naturally, and enjoy yourself."

Penny nervously stood over the doctor, her legs between the doctor's spread legs, her thighs touching the older woman's thighs. "C- can I kiss you, Dr. Grace? I always dreamed about kissing someone."

The doctor nodded hesitantly, reminded of how inexperienced and innocent this girl was.

Penny leaned forward to kiss the older woman, and felt Grace's soft ample tits mash against her much smaller breasts. Penny kissed Grace, timidly at first, then more passionately, licking Grace's lips with her tongue, then biting gently, eliciting a moan from the older woman. Grace wrapped her arms around Penny's narrow waist and squeezed her round little ass. She nodded to the young girl with a lustful gaze. "Go ahead, Miss Thompson. Make love to me."

Penny gulped, nervously grasping her rock hard cock with both hands. She positioned the head of her cock at the doctor's wet slit, then pushed slowly forward with her hips. The head of her cock disappeared through the folds of Dr. Grace's labia. Penny couldn't believe how slick and warm the doctor's pussy was. It felt amazing, much better than touching herself. She thrust deeper into Grace, first two inches, then four, then six, until she felt resistance. Three inches of her powerful cock was still exposed, allowing her to see in exquisite detail how the older woman's pussy lips gripped her veined shaft.

The doctor groaned and arched her back as Penny began to thrust her cock in and out, awkwardly at first, but quickly figuring out a steady rhythm. The girl's shaft was coated with Dr. Grace's slick fluids, creating a sexy squelching sound.

"Oh... fuck, you're a natural at this, kid. Now, rub my clit, just like you would rub your own when you're alone." the doctor growled, her eyes half-closed in ecstasy.

Penny reached down with her right hand and gently caressed the doctor's clit with her thumb, which caused the older woman to groan louder and roll her hips in time with Penny's thrusts. With her left hand she grabbed one of Grace's tits, sinking her fingers into its supple flesh, feeling the large nipple on her palm.

"Oh gosh, oh gosh..." Penny moaned. "I love you, Dr. Grace... I love you!" She mumbled as her movements sped up.

"Oh fuck... Don't... be silly, dear..." The doctor panted. "You barely... fuck... barely know me! God... keep going, I'm... almost..." Dr. Grace gritted her teeth and arched her back, her face turning red as she neared her peak. "Harder! Faster!" She demanded.

Penny obeyed the doctor's command. She grabbed Grace's hips for leverage, and plunged her cock deeper into Grace's cunt. A bead of sweat rolled down Penny's forehead, her frizzy red hair stuck to her temples as she fucked the doctor with increasing vigor. She watched in awe as Dr. Grace's tits bounced and jiggled with each thrust.

"Oh god yes!" Grace yelled. The woman's body began to shudder and tremble as she reached her climax. "Fuck... I'm... coming!" Her cunt clamped down tightly around Penny as she orgasmed, her muscular cunt milking the young redhead's cock.

Penny cried out as her cock was squeezed from all sides. "Oh gosh! Gosh, oh gosh! Dr. Grace!" She shivered as her body tensed up, approaching her own climax.

Suddenly, a voice called out from behind Penny. "Dr. Fellows, I'm about to leave for the afternoon. Do you need anything else from... On my god!" Mrs. Hamada stood in the doorway. Her mouth gaped, and she dropped the stack of files she had been clutching.

In a panic, Penny pulled her nine inches out of the doctor's spasming cunt. She spun around instinctively to face the unexpected intruder, but she had passed the point of no return. She yelped in a combination of horror and ecstasy, as a jet of white hot cum shot out of her cock. It flew through the air with surprising force, and splattered on the plump Asian receptionist's sandaled toes, five feet away.

Another jet of cum shot out and struck Mrs. Hamada in her ample chest, covering her modest brown sweater. The third shot streamed down her plump, round belly and dripped onto her skirt. Penny grabbed hold of her penis with both hands as her ejaculations subsided, but continued to squirt pulses of semen onto the floor between her and the chubby receptionist.

Mrs. Hamada stared at Penny's cock in disbelief, then at the splatters of cum on her sweater and bare toes. "Futa... Futanari!" The older woman blurted out.

Penny finally finished cumming with a whimper, then started crying, mortified. "Oh gosh... Mrs. Hamada..." she said. "I'm so sorry..."

The Asian woman looked at the two naked women in front of her, their bodies slick with sweat and cum, breathing heavily. Dr. Grace Fellows was still orgasming softly, fluid pulsing from her pussy with each contraction, while Penny's cum puddled on the floor. Mrs. Hamada's cheeks flushed and she chewed her lip. She seemed to be torn, between running away and absorbing every detail of the lurid scene.

Dr. Grace sat up, her mature tits still heaving. She patted the bed, motioning Penny to sit down beside her. Penny grabbed a satin sheet from the bed and hastily covered herself, and tried to avoid eye contact.

The doctor wrapped a muscular arm around Penny's shoulders, but didn't bother covering herself, exposed and dripping without shame. She turned to her receptionist. "Mrs. Hamada... Marci... please shut the door and come in. Lock it." The other woman nodded meekly, and compiled.

"Come over here, sit down."

Marci Hamada walked over timidly and sat in one of the chairs facing the bed. "Marci, my dear... Miss Thompson here was just helping me test out a new err... spontaneous therapy technique. I didn't mean for you to see that, and I certainly didn't mean for you to get cum on your clothes. But I'm curious... What was that word you said? Futa...?"

"Futanari," Marci mumbled. "It's a Japanese word for... a woman who has a penis. But it's mostly used in pornography. In fantasy." The plump woman blushed furiously, but snuck a curious glance at Penny.

"Futanari, I like that!" Dr. Grace mused. "An apt term for your unique gifts, Penny." She stroked the younger woman's freckled cheek, wiping away a tear. "Don't worry, Penny, this is a sex therapy clinic. Marci knows all about discretion and confidentiality."

"Of course I do," Marci agreed. "Miss Thompson, you don't have to be embarrassed. I've never... I don't get to see things like that." She smiled wryly, "Not in real life anyway." Marci glanced down at the strands of cum drying on her sweater. She flexed her bare toes, and felt warm cum ooze between them.

Penny looked at the receptionist's soaked shirt, sniffed, and smiled nervously.

"I have a proposal for you both," Dr. Grace said with a clap. She took a deep breath. "Penny here is incredibly special. Not only is she adorable, sweet and kind. Not only does she have a magnificent cock. It seems that her semen is potent enough to give an older woman like myself two of the most powerful orgasms I've had in my life. And if she's willing, I'd also like to see if her talents could help some of our other clients." Dr. Grace made eye contact with her receptionist, and grinned. The plump woman held her gaze for a moment, then lit up with understanding.

"Oh my god..." Marci breathed. "Do you mean... I get to be in those experiments?"

Dr. Grace smiled and nodded. "If Penny agrees, of course. I've known you for years now, Marci. First as one of my clients, and later as my assistant, and now as a friend after your husband passed. I've always felt guilty that I couldn't help you overcome your sexual blockage."

Both older women turned to look at the lithe young redhead.

"What do you think, Miss Thompson?" Dr. Grace asked.

Penny stared at the doctor. "So you... you want me to have sex with your clients? So I can help them orgasm?"

Grace nodded. "I don't want to interrupt your college classes, but if you're available once or twice a week, I could bring you on as a paid consultant. Think of it like a special internship. You'll be compensated handsomely, you'll be helping a lot of women... and you'll get a lot of sexual experience." She winked mischievously at Penny.

Penny twirled her hair thoughtfully for several moments. She looked at Marci Hamada, who was practically bouncing on her toes with excitement. The young redhead giggled and said, "When can I start?"
