Joanne's Art Modelling (nsfw+nude variants)

Joanne is walking through the hallway to a college classroom to meet an old friend who teaches art at said college. She soon reaches the classroom and her friend offers her a deal.

"Look, you won't be doing it for free, you'll be compensated for your time, not to mention I've prepared a swim suit for you to cover your dignity if you're not comfortable naked." Her friend said in a pleading manner. "You'll really be helping me and my students out."

"Well, if you say it like that..." Joanne said, beginning to warm up to the idea. "And I won't have to be naked?"

"Well, it would help me a lot if you were, but I won't push you" her friend conceded. Joanne sighs, and accepts to help her. "Great! You can get changed before the students come in"

Much to Joanne's horror, the swim suit was a tiny bikini that barely covered her nipples and crotch, and was held together by threads.

"You look great, Joanne! Oop, here the boys come!" A handful of boys walk into the classroom, visibly stunned by Joanne's voluptuous curves and her tiny bikini. It was too late to back out. "Hold this pose for us for about 15 minutes if you can, Jo." Her friend showed her a photo.

Horrified but putting on a brave face, she kneeled on a soft matt on the floor and set her legs ajar and put her hands behind her back to support her. She could feel the entire classroom ogling her exposed form.

Joanne was trying not to think too hard about the situation she'd landed herself in, as she looked at the several students in the class trying to paint her mostly naked body. She could hear some of the students whispering and pointing at her. She noticed the boys now had stiff bulges in their trousers.

"Don't mind that Joanne, these are relatively young men after all, they're probably very enamored by your voluptuous form!" her friend laughed. This did not help Joanne's embarrassment, or the students for that matter.

Suddenly, she was startled by a student that let out a loud "Oh!" and the feeling of a liquid hitting her body.

"A bit too soon for you to blow your load isn't it?" her friend teased the student, who had accidentally emptied his tube of white paint on Joanne. The rest of the class were visibly aroused by what looked like someone had ejaculated on her. Aware of what it looked like, Joanne blushed a bit redder.

As the minutes slowly dragged on, she began to start shifting her weight to reduce her discomfort. The fabric of her bikini bottoms began to rub against her genitals, and she slowly became more and more stimulated. Joanne finally unable to hold it in, climaxed and let out a moan. Her bikini bottom now had a wet patch, and fluid began to leak onto the mat.

"I wasn't expecting you to uh... enjoy yourself this much, Jo!" her friend laughed. Joanne looked down in horror as the ecstasy gave way to humiliation at the fact she'd just climaxed in front of a small crowd. "Don't worry Jo, I'll wipe you down." Her friend removed her bikini, much to Joanne's horror, and walked away to grab a cloth.

The students at this point had completely stopped painting and ogled her naked body and her dripping crotch.

"Hey, who said you guys could stop painting? She's holding the pose for a reason you know." her friend said as she wiped Joanne's body clean of the paint and wiped down her crotch. "Well I can't let you wear the stained bikini now, you'll just have to remain like this until the end of the class!" her friend smirked. Joanne let out a sigh and held the pose for the remainder of the class, completely naked.
