Iris spent most of the weekend with Eddie, trying to forget the events of Friday night. He was great. She finally convinced him to watch the Pride & Prejudice miniseries with her, and by Sunday morning she was starting to feel better.

"Did you end up having another session with Professor Brenn?" asked Eddie.

"Yeah, but that's probably the last one." she replied.

"Still, it's pretty cool. He's going to unveil some new pieces at the school's next exhibition. I've heard that he was planning to donate one to the city's museum. It's crazy to think there might be a picture of you in the new collection."

Oddly, Iris had never considered that the pictures she modeled for would be shared with the world. Her sessions with the Professor had felt so intimate and secluded that they seemed private from the rest of the world. She felt her anxiety growing once again.

"Hey, I'm going to head to my room and take a nap. I'm kind of beat." she said.

"Oh, alright. I guess I'll see you later then."

Iris wanted to take a walk alone. Generally, she would have done some schoolwork if she was feeling stressed, but she was so far ahead after her marathon of a couple days ago, even she found it hard to justify. She walked through central campus enjoying the unseasonably warm weather.

"Hey, Tight-Pants! You wanna play frisbee with us?" Shouted the stoner from the other day.

"No thanks, maybe some other time." she said. His antics were a welcome distraction.

"I'll hold you to it. Later Tight-Pants."

Iris got back to her room and considered taking a nap, but first, opened up her laptop to check her e-mail. At the top of her inbox was a message from Professor Brenn.

Iris, Come to my office hours tomorrow promptly at 9am. I have something to discuss.

After reading his e-mail, she decided to take that nap. She didn't want to think about it.

The next morning Iris did as she was told, knocking on Professor Brenn's office at 8:59. He opened the door and led her in, closing it behind her.

"Sit down." He gestured to the seat in front of his desk. She sat.

"I have some things to explain to you about Friday's session Iris." he said. Sitting behind the desk.

"Alright." She apprehensively awaited what he would say.

"I want to apologize for what happened before I left Friday's session. It was totally unacceptable on my part."

"What was unacceptable?" Iris was genuinely confused.

"When I was sketching close to you at the end of the session and became aroused. I was sure you noticed."

She was so preoccupied with herself that it was one of the few times she wouldn't have noticed him.

"I didn't though." she said.

"Well, that's sort of beside the point. The problem is what happened, not what you saw. Unfortunately, this creates an additional problem. You're now one of the primary subjects in my next show, but I don't have everything I need from you, and I need another session. The only angles I require are of your face, neck, and hair. So just wear your hoodie and jeans and I can make do. You're available tonight at the usual time?"

It was barely a question. His placating aspect had faded away quickly.

"Yes. It will be the last session?" She asked.

"Yes."

Iris left the office rather dumbfounded. She was generally naive to the effect she had on most men. Eddie regularly gave her compliments, and with a bit of convincing, she believed he was attracted to her. But with other people, it was hard to grasp that her looks would have such a material effect. It seemed almost impossible that a grown man like Professor Brenn, an attractive and successful man, could become turned on just by sitting that close and looking at her, even with her unfortunate transparent panties.

The next thing she knew, Iris was knocking on Eddie's door.

"Hey, what's up?" asked Eddie.

"I just needed something." said Iris. She began taking off her pants, still in the hallway outside of Eddie's dorm.

"Sorry, I wasn't expecting you. I need to leave for work in like ten."

She held Eddie close for a passionate kiss, grinding herself into him.

"Alright, I won't complain."

Eddie pulled off his shirt as Iris led him to the bed. She helped him strip down the rest of the way as he laid back. Iris left on her tight rib-knit shirt but took off her pants and then did something that was rare for her. She removed her underpants and straddled Eddie's bare legs. His penis engorged quickly as he stared at her nude lower half. She spat into her hands and started to rub his member. He had never seen her spit before, and the crude nature of it aroused him incredibly.

Eddie was clearly enjoying himself but seemed to be missing the point entirely. Frustrated with him, Iris decided to make it more obvious. Still straddling him, she lifted her right leg which unambiguously displayed her vagina. He continued to stare at Iris as she stimulated him, but he didn't try anything else. She was getting restless. Making her aims even more apparent, she slid up his body until her vagina rested on the base of his penis. He held his hands on her hips while she started to grind against him slightly, her spread vagina gliding along the bottom half of his erection.

Iris needed it, but she wouldn't go any further herself. She was right there and wet and all he needed to do was pull her hips forward a little bit. But instead, Iris watched as her cowardly boyfriend ejaculated on her hands. Afterwards, he said something about helping her out too, but she ignored it -- wiping the semen off on his sheets.

"I need to get going. I scheduled another session with Professor Brenn by the way." she said.

"Really? That's great. Thanks for stopping by unexpectedly, and feel free to do it more often." said Eddie, wearing a dumb grin across his face.

She put her clothes back on, trying to hide her frustration. After Iris was dressed, she gave Eddie a peck on the cheek and left.

The rest of the day flew by. Iris decided that if she was going to be featured in Brenn's show, she would put her best foot forward -- it was the last session after all. She repolished her finger and toenails and applied her makeup with care, though she never wore much. The real concern was her hair. It was one of the few things he planned to focus on, but it was raining all day, and the temperature reached the mid-seventies in the afternoon. The humid air caused her long curly hair to poof out incredibly no matter what she did. She finally decided to give up and pulled it back in a huge ponytail, spraying a light gel on the taut hair of her scalp. She slipped on a pair of thong sandals, showing off her red toenails, and left her dorm.

When she arrived at the Art Building, Iris decided to rework her ponytail. As she was tucking her hair into the last tight loop of the hairband, it snapped. It seemed like there was always something that went wrong in these situations. She tossed the broken band into a trashcan and made her way to the fourth floor -- long poofy locks flowing behind.

"You made it." Said Brenn as Iris neared the room.

"Yes, where am I going to be today?" she asked.

Iris removed her sandals outside of the studio and left them in the hall. Her bare feet slapped against the cool tile floor as she approached the Professor.

"Let's keep it simple today."

Brenn picked up the paisley pillow and set in on the ground about eight feet from a stool and easel.

"An easel, getting fancy today, Professor." Iris quipped.

"I do tend to prefer the finer things." he replied.

"I bet you do."

Iris sat directly on the paisley pillow, tucking her legs in against her left hip. She stared at Brenn as he drew her and considered what he said in his office. Did she really have that much of an effect on him last time? He assumed she noticed, and that meant what? That he got an erection. Was he attracted to her? Did he think she was sexy? Was he a little horny right now? Probably not in her jeans and hoodie. But when she thought of it, the room was getting kind of warm.

"Could I take off my hoodie?" Iris asked.

"That would be fine. I opened some windows, but the room still heated up." he responded.

She stood up an unzipped the hoodie. Brenn took the moment to glance at the messages on his phone. She tossed the hoodie off to the side, Iris wasn't wearing anything underneath. Brenn looked up and saw her exposed breasts -- running his eyes over her bare skin.

"A bellybutton piercing. I wouldn't have expected." he remarked.

Iris didn't stop. She popped the front button of her pants and unzipped the fly and slid down her tight jeans. She wore no underwear. Her body was completely naked to him, with long dark hair a high contrast against her soft ivory skin.

"Sit back down." Brenn ordered.

She obeyed, sitting down on the pillow. Her already thick hips widened slightly as her butt pressed into the cushion. He continued with his art, seeming unfazed by the situation. It surprised her that the Professor made no further remark after that. Perhaps it didn't have the effect she expected, and the previous session was a fluke. Iris was past the point which she had planned for.

'Look at him -- handsome, tall, well groomed, well respected. What could you expect?' She thought.

Iris wasn't even sure what she wanted if he had reacted. Would they have had one magical night for her to keep as a youthful memory, or was she destined to chicken out if he returned her advances. So, she just sat there and considered the answer, totally naked, in front of her Professor.

The jolt that Iris felt stripping in front of him was short lived. Since telling her to sit, Brenn seemed all business. At one point he did stand up and walked over, telling Iris to angle her chin up till her pouty face was aligned with his. He towered above her, and the moment felt like it could lead to something, but he returned to his work.

She grew petulant as her desires clarified in her mind. Iris wanted Brenn to touch her. No, she wanted Brenn to fuck her. She wanted to feel him, not Eddie, inside of her -- to witness him lose control as he took what he wanted. And most of all, for him to want her, but Brenn kept drawing and drawing. At this point Iris began to second guess her wild decision. Her eyes reddened a little as panic set in. He was completely ignoring what happened and acting like a total professional.

Iris's crush on Professor Brenn was profound, and as much as she hated herself and tried to ignore it, she was entirely unable to. It caused her so much confusion that she had made one bad decision after another. That moment being her life's crowning achievement in stupidity. She started to feel bad for Eddie and wondered if she could drop Art History. More than that, she was just ashamed.

"I think I should put my clothes back on." she said.

"No, we're almost done." Brenn stated flatly.

Iris looked at the clock. They had only been there ninety minutes. Maybe she should just leave, the money wasn't too important. She could just stand up, put on her clothes, and leave. But before she made her choice, Brenn stood up.

"Alright, I'm finished with that. Good session overall." he said.

She did it. She was free. All she had to do was put this stupid day behind her. Iris began to get up.

"Where are you going?" Brenn asked.

"To get my clothes." she replied timidly.

"You stay there." He instructed.

"Yes Professor." Her bleak hope sprang back to life.

"I'm assuming it wasn't an accident that you stripped completely naked in front of me."

"You told me to 'just wear a hoodie and jeans'."

"What?" asked Brenn.

"You told me 'just wear a hoodie and jeans' and I asked for permission to take off the hoodie. I'm sorry for taking off the pants without asking."

She wasn't stupid, her actions were very deliberate. It was clear to Brenn that Iris wanted to seduce him, but she seemed to need some context to make her comfortable with the situation. Brenn thought for a moment, trying to figure out the rules to the strange game Iris was playing. He reworked his entire show to feature her. He was losing sleep thinking about this woman. He couldn't mess this up.

"So, you do everything I tell you to do?" he asked.

"Yes Professor."

Bingo, he had it, but he needed to be careful not to overplay his hand. She needed him in control, but that didn't mean he couldn't scare her off. Brenn reclaimed his domineering attitude and walked toward her. Iris enticed him completely -- her sharpness, her absurd self-consciousness over her perfect body, her desperate need to please him. How could he help it? She looked up at him with her dark eyes, which offered everything.

"Touch yourself." he said.

She said nothing, but adjusted her legs, splaying them on either side of the pillow clearly revealing her vagina. Using the pointer finger of her right hand she massaged her clitoris. The room was completely silent aside from her quickening breaths and the faint wet sound of Iris caressing herself. She never looked away from his eyes as she did it. He never told her she could. Not stopping or slowing, she continued to work herself with a deliberate focus. It wouldn't last long with him so close to her, watching her. Iris's upper chest blushed a deep pink as she crescendoed towards her climax.

"May I? Please!" She pleaded.

"What?" he asked mildly.

"May I come in front of you, Professor?"

"You may."

He scarcely got the words out when she began to shudder violently from her hips -- arching herself sharply forward as she balanced her weight upon one rigid arm. Two of her fingers now penetrated firmly into her, making a lewd squelching sound while she continued to masturbate through her orgasm. Iris's breasts trembled noticeably, her erect nipples tracing tight circles in the air as she continued to shake.

Iris was shocked by the size of her orgasm. Her cries were enormous, she was so caught up she didn't even try to stifle them. The large windows of the room stood wide open, anyone outside could have heard. When the it had subsided, Iris was still mildly vibrating from the adrenaline. She was ready to slump onto the ground and could have laid there indefinitely. Instead, she sat back up to face him, badly wanting to touch him and he to touch her. But Brenn turned and started for the door.

"That will be all for today." he said. "You'll come back for another session tomorrow. I'll let you know when."

Iris didn't respond. She would come and he knew it. After Brenn had left, she stood up from the paisley pillow. It was now damp from her fluids.
