We start Part 2 from the point of Chazz, Louisa's stepson...

“Sons? I wonder. I think we’re going to find out.”

“Definitely.”

“Boys,” my mom ordered. “Follow us.”

Our dicks still bulging madly against my mom’s panties, we followed them into the master bathroom. The two of them wore tight designer jeans that clung to the perfect round sweep of their asscheeks and haltertops that molded to their slender waists and luscious breasts.

When we got into the bathroom, they shut the door and turned on the shower full hot, billowing steam into the room. Soon we were all sweating. Mom and Aunt Elena peeled off their tops and jeans, leaving them in translucent white bras and panties that clung to their breasts and major labia that obviously had been waxed. The two sisters were such intensely sexy creatures that it gave them as much authority over us two guys as did their role as mothers.

“We need to cleanse you two properly if you’re going to be our sissy girls,” Mom announced. “We’re starting with a steam bath to open your pores and purify you, give you feminine skin.” She pointed me at the closet. “Get out a couple of beach towels, Chazz. Lay one out in front of the shower.”

At her direction Woody took off his panties and got face down on the towel. His back and legs and shapely butt glistened with sweat. Mom handed me a tube of a sweet smelling, gritty but slippery lotion that read “apricot scrub” and told me to thoroughly massage my cousin’s entire backside from his feet to the base of his scalp. Woody’s muscles and skin felt so good under my hands, and his moans of pleasure made my dick stay hard.

When our moms had him roll over I saw his cock was as hard as mine. All I could think of was that I hadn’t gotten to suck him off yet. My frustration must have shown in my face because Aunt Elena remarked on it, asking if I felt left out.

“Is she right?” Mom asked. “Do you want to give your cousin a blowjob before you scrub his front?”

“Yes.”

“Yes, what?” my stepmother demanded, her eyes glinting.

“Yes, Mom,” I breathed.

“Then go ahead and suck your sissy cousin’s dick. Give him a blowjob in front of Mom and Aunt Elena.”

Swooning with lust at the naked perversity of what Mom had just said I took the base of his cock and lifted his boner just enough so I could get my lips around it. A fat drop of precum had beaded up and without thinking I licked it up. It was salty-sweet and it made me want to drink his cum. I took him into my mouth and began sucking him off. Woody’s deep groans filled my ears.

“Now you be sure you don’t cum in his mouth just yet,” Aunt Elena instructed.

“Tell him when you’re getting close to cumming, Woody.”

“Yes, Mom,” he said.

“Mommy,” she corrected, with a twisted smile.

I felt Woody jerk underneath me as he gasped in shock.

“Ohmigod!” he cried. “Stop or I’m going to cum!”

I pulled my mouth off of him so he wouldn’t get in trouble. Or me.

“My son, the sissy cocksucker,” my mom sneered.

“Yes, Mom,” I said, humiliated.

“Now get back to scrubbing him.”

Thirty minutes later Woody and I had thoroughly scrubbed each other, our skin glistening with the lotion and crusty with the grit. The hot water continued to run in the shower and steam billow. Our moms were so sweaty their lingerie stuck to their ripe bodies, completely transparent. Their nipples were hard and their pussies were fully visible. Woody and I were still rock hard.

When my stepmom walked into the shower I couldn’t take my eyes off her essentially naked ass. I heard her adjust the water and immediately the steam stopped, so I figured she’d set it to warm so Woody and I could wash ourselves clean and get ready for whatever they had planned next. Then I heard something filling with water and a moment later, something else filling.

My eyes got wide when Mom stepped out of the shower with a pair of enema bags that bulged with water. It had to be a half-gallon in each. She smiled with a wicked playfulness as she pointed to the beach towel on the floor.

“Both of you,” she ordered. “On your knees, spread wide, chins resting on the towel. We’ve cleaned your outsides and now we must clean your insides. You’ll see why a little later.”

Having watched all of that porn over and over, I had already had a good idea why. I knelt next to Woody and stuck my ass in the air, knowing that the cramps from this much water would be exquisite. Mom had given me an enema when I had mild food poisoning six months ago, only half as much water as this, and it caused cramps and chills that were like torture for the first minute. And then it had started to feel so good I got a boner from it. She hadn’t said anything then but she probably saw it.

I shivered when her slippery finger pushed right up into my asshole and I couldn’t help groaning aloud. One moment later the cool plastic nozzle slid deep up my ass; it was one of the big long ones used for douching. I heard Woody groan as turned to see Aunt Elena sliding the nozzle up his ass. Our dicks were still throbbing. One second later I heard the double-click of the valves being opened.

The pressure built immediately deep up in my ass when the warm water barreled into me. It felt so sexy having my rectal tunnel filled, but then the cramps hit. They seized me with a pain like a dull knife deep in my guts.

Woody and I cried out at about the same time, a keen sound of anguish. We whimpered as the pain backed off from its peak but still continued to torment. Tears rolled down my cheeks and I could see Woody crying too as the water didn’t even slow down. Then the pain built again and our whimpering turned into sobs.

Suddenly I felt the soft warm skin of a feminine hand gently grasp my still raging erection and milk it. Almost immediately the pain collapsed into a low ache replaced by a building pressure in my balls. Woody gasped right next to me and then moaned. I looked up to see Aunt Elena had reached down and was jacking me off, turning my pain into pleasure. At the same time my mom was masturbating my cousin, whose moans grew louder and louder.

In that moment I heard the sound of an enema bag running dry and the pressure on my ass backed off. All two quarts of water were deep up inside me. One minute later I heard Woody’s bag empty. The two of us knelt naked on the bathroom floor, hoses running out of our buttholes and a half-gallon of water torturing our bowels while each other’s moms stroked our throbbing hard cocks.

“I’m gonna cum, Aunt Louisa,” Woody groaned.

“Go ahead and cum, sissy,” my stepmom told him.

He cried out, gasping and panting and quickly the smell of his jizz filled my nostrils. The odor pushed me over the edge. I was about to spurt and I told my aunt.

“Shoot your wad, “ Aunt Elena said.

I felt the palm of her free hand cup the head of my meat. With an explosive, rumbling ache my balls contracted and pumped what felt like a fat load of cum into my aunt’s waiting palm. The next thing I knew the tube had been pulled out of my butt. I clamped my sphincter down tight.

“Up on your knees, both of you,” my mom ordered.

She moved in front of me, trading places with her sister. She thrust out a hand filled with Woody’s cum while Elena shoved my spunk before him. I didn’t wait for her to order me—she didn’t need to—I wanted to drink his boy-juice—and I stuck my tongue into the middle of that white, sticky puddle and lapped up the salty cum like a hungry cat.

I finished it and turned my head to watch my cousin licking up my jizz. He looked so hot doing it I couldn’t tear my eyes away. When he finished he looked up at me with adoring eyes, his lips white and sticky, and we pressed our cum-covered mouths together, licking up the rest of our eruption in a passionate French kiss I didn’t want to end. Finally I heard Mom clear her throat and we broke the kiss.

“Boys, it’s time to empty yourselves. Woody, use the toilet over there. Chazz use your father’s bathroom. Then take a good long shower and report to the bedroom. We have so much left to do to make you our sissy daughters.”

Feeling the pressure of the water on my asshole, I scooted quickly toward Dad’s bedroom, a former guest bedroom next to my mom’s. The strangeness of this day was far too much to comprehend. It would be best if I didn’t to think about it too deeply and just let it happen. So far our moms hadn’t really punished us, and as scary as it had seemed it was also deeply erotic.

My last thought as I clicked on the bathroom light was that this was all because I had stumbled on that stash of smut in the storage locker. I decided not to be afraid any longer but a small part of me worried just how far Mom and her sister would go in having their way with us. It was one thing to fantasize about all that kinky sex in those pictures and videos. It was quite another to go through with it, especially with my mom and aunt!

I wondered what my mom was thinking just now.

Mother Knows Best

I sat on the side of the bed with Elena, listening to the sound of her boy in the shower. Chazz was across the hall in my husband’s bathroom. Elena and I were still sweaty from all the steam. Our fine lingerie was plastered to our bodies. We might as well have been naked. We gave each other smoldering looks, playing our little game of tease and delay. It had been two weeks since I’d visited Elena in Las Vegas, but instead of jumping on each other when she and Woody showed up yesterday my sis and I had waited for this moment.

“God you look beautiful, Louisa,” she said.

“You too, little sister,” I said.

I brought my lips to hers and kissed her with all the helpless passion I’d had for her since we’d been teenagers growing up together. Her hand stroked my tingling labia through the moist triangle of my thong panties. Not to be outdone I slipped my long middle finger under her panty waistband and gently traced down her slippery pussy lips until it slipped easily into her milky snatch.

“Oh you’re the hottest sister anybody ever had,” I gushed.

Elena gave me a gentle smirk. “The boys are in the shower. It’s just us in here. So why keep up the sister charade when there’s nobody to hear it right now?”

I pouted. “I’m hurt that you’d call it a charade. After all we were sisters growing up, even if we didn’t have the same parents.”

Elena came to live with my father and me when her parents—major stockholders in Dad’s firm—died in a car crash. I’d been a senior in high school and Elena was a junior. It had been love and lust at first sight. By her third week of living with us we were taking turns sleeping in each other’s beds. Fortunately my father was a heavy sleeper and clueless when it came to the steamy lesbian relationship under his roof.

The main reason for our subterfuge was because my father had died intestate. When probate finally cleared only his children will get that money, and he never legally adopted her. While I’d never allow my sweet Elena to go hungry, the Feds would massively tax anything I gave her as a gift from her rightful inheritance. I’d paid off the right people to have the official records destroyed, so all I needed to do was swear under oath she was my real sister. There was nobody who could or would contradict that.

“You know the real reason, my love. I want you to get your full share… Sis.”

“Oh, I love you, big sister,” Elena said crushing her lips to mine. Our tongues swirled hungrily together.

I broke the kiss. “Of course there’s one more reason.”

“Such as?”

“Freak that I am, I love the thought of real incest with you.”

“You’re such a perv,” Elena chuckled.

“Besides, wait until we make love in front of the boys. They’ll flip!”

For the next five minutes, until we heard the shower cut off, my sisterling and I deep kissed and toyed with each other’s clits We forced ourselves to hold down our ecstatic moans, which became louder and louder in our mutual fingerfucking. In our play I imagined Elena as my real sister. So hot!

Elena broke our lengthy mouth lock. “Speaking of flipping, what do you think Woody will do when I tell him?”

“What? That you adopted him as a baby when his real mom died?”

“What else?”

“Why tell him?”

“Because even before he turned eighteen I’ve wanted him to fuck me. I don’t want him to feel unnecessarily guilty.”

“Don’t. Just tell him ‘mother knows best’ and he doesn’t have a choice.”

“Perv,” my adopted sister grinned as she stroked my clit.

“Oh, god, little sister,” I moaned. I kissed her again. Then I pulled back and looked thoughtfully at her. “Besides, when we’re done with these two boys they’ll be so deep into their new lives as sissies they won’t question any of it.”

The shower cut off.

“It’s showtime,” I said, standing and holding out my hand to my adopted sister.

“So should we put on the boots and dominatrix stuff?”

“Maybe later,” I said. “I think we do this first bit au natural.”

Elena and I stripped naked and we stood side by side in the center of the room, our feet spread wide and our arms folded underneath our juicy, sweaty breasts. Moments later Woody slunk in, his head down and his face red with embarrassment. He acted like he’d been fully debased by giving head to his “cousin” in front of his “mom” and his “aunt.” Not to mention we’d given them humiliating enemas. He and Chazz had no idea what they were in for.

“Kneel in front of me, Woody,” I commanded. “Keep your eyes on my feet and don’t speak until spoken to and given permission to reply.”

The beautiful eighteen-year-old boy knelt in from of me, his shoulder-length blond hair falling down the sides of his face. Two minutes later my stepson came in looking equally cowed. He seemed to understand what he was supposed to do because he knelt in front of my sister and assumed the proper position.

“Boys,” I began. “Look up into our eyes.”

I loved what I saw: trepidation mixed with timid desire. Our nude bodies—even though they thought of us as their mothers and aunts—had a powerful effect on them. Sure enough their cocks were hardening, making them that much more our slaves. Speaking in an authoritative yet kind voice, I laid down the law.

“That will be the last time we ever refer to you as boys… at least for a good long while. We said we’re making you into our sissy daughters, and so you shall be. That includes your names. However I’m still giving some thought what I’m going to call you, Chazz, and I believe Elena still wants to think further. Right, Sis?”

“That’s right big sister.”

My pussy was now really starting to tingle and my clit ached with lust, anticipating what was coming next. “Do you sissies understand?”

Two cute mouths with lips almost too delicate to belong to boys quivered as they looked at me in shock. The both mumbled yes.

“I see a lesson in manners is called for here,” I said tartly. “When you speak you shall do so clearly and you will address both of us as ‘Mistress’ or… ‘Mommy,” I finished with a twisted grin. “Personally I prefer ‘Mommy.’ So does my sister.”

“Yes, Mommy,” our sons said.

“Now, you might think you two understand your place, might feel that you have been thoroughly degraded and humbled with the cocksucking and the enemas, not to mention kneeling nude in front of your mothers. Wouldn’t you?”

“Yes, Mommy,” the sissies said.

“Perhaps. But I’m not fully satisfied. Elena?”

“Yes, sister dear?”

“Time to make them submit further.”

We both turned around to face high-backed chairs we’d been standing in front of. We spread our feet wide and bent over the chairs, gripping the backs for stability. I felt cool air on my parting pussy lips and on the soft pucker of my asshole. Based on where the sissy boys were kneeling they faces were mere inches away from our anal openings. My “nephew’s” lips were within kissing distance of that one orifice most people considered the nastiest on the human body.

“Lick my asshole, Woody!” I commanded. “Chazz, you lick your aunt’s asshole. You sissies know what French kissing is. We want you to French kiss our assholes. We want your tongues not just licking all around our asses but we want to feel them going up into our butts.”

The boys both gasped simultaneously. I smiled to myself because I had also heard an inrush of desire as they inhaled.

“You better satisfy me, Chazz,” my sister growled. “Otherwise your tongue is going to be my toilet paper for the next week. I mean that, sissy!”

One second later I felt Woody’s young lips tentatively kiss my anal sphincter, his tongue flicking out in scared little thrusts. Instantly my clit began throbbing and I felt my pussy juicing up. Secretly I was delighted but Elena had the right idea: we had to instill awe and fear into our adopted sons. The sooner they complied, the sooner their kinky passions would take over and they could handle what appeared on the surface to be incest. That would take them as far down that kinky path as we wanted them.

“You can do better than that, Woody,” I chastised. “It’s clean enough back there for now. But I agree with your mom. You’re going to be cleaning both of us up after we use the toilet for the next week unless I feel some enthusiasm. The same goes for you, Chazz. Now make love to your mommies’ assholes like you really mean it!”

Elena gasped all of a sudden and I saw that Chazz had pushed his sweet lips deep into her asscheeks and his hands had come around to grip her hips, pulling her butt more fully into his face. Woody followed suit and the hot, moist snake of his tongue began burrowing at my butthole, intent on pushing up into my rectal region.

After three minutes my anal muscle had loosened up and I felt the young sissy pushing up into my anus. He was whimpering with lust. A look down between my legs revealed his seven inches were throbbing hard and jutting straight out.

This was the moment.

“I see your dick is hard as can be, Woody. Do you love rimming your aunt? Do you love the taste of my asshole? Do you love being an asshole-licking sissy slave and a cocksucker?”

With great triumph I heard the muffled moan of “yes” between my asscheeks. My nephew was ready for the next step.
