"Are you comfortable enough in that pose that you can hold it for a while?" Lisa asked Kjem. It was his second day of modeling for Lisa's class. The first day had been plain modeling, barely R-rated, while the students sketched. He was lying on his side on a minimalistic black couch, the kind you might see at IKEA, in his boxers. He was propped up on one elbow, with his head held in that hand. His opposite knee was up, spreading his legs a bit.
"Yeah, I think so," he answered. There were six or seven students setting up in front of him, spread out on the floor or in chairs, with drawing pads or easels. One student, introduced as 'Annie', had an expensive-looking camera taking video as unobtrusively as possible.
Lisa, wrapped in a smock that looked a bit like a lab coat, wandered up to Kjem and made a couple of minor adjustments to his position and the couch cushion, giving him a peek at her unencumbered tits in the top of her smock. When her head was close to Kjem's she whispered into his ear. "Did you take that blue pill before you came here, like I asked?" Kjem nodded.
Lisa stood back, and still facing him let the top of her smock open to give Kjem a better view. With her back still to the students, she acted like she was adjusting the smock, but in reality, she was giving Kjem ba it of a show. She had nothing on underneath the bottom of her smock either, except for leggings from mid-thigh down.
After she re-adjusted her smock, Lisa turned to the students and gave them instructions for making sketches and writing down ideas, and admonished them to focus, then took a seat in a directors chair behind the students with a clear view of Kjem.
While the students got to work, Lisa slouched in her chair and let her legs open so that the smock slid over on either side of her legs. Locking her eyes onto Kjem's, she hitched one leg over the arm of the chair, exposing her bare pussy his gaze. The smock was still tied in the front, so that she was still covered from the waist up, but somehow this made her look even more exposed. Kjem could feel his dick chubbing up in his boxers despite his self-consciousness. The students saw this and started giving smiling glances at each other.
Annie, unnoticed to one side, panned over the students to catch Lisa exposing herself on film. Lisa must surely have noticed this, but she kept her gaze locked onto Kjem's eyes and instead lifted one hand and inserted a middle finger into her mouth. Drawing it in and out of her mouth a few times to wet it, she then lowered her hand and began to lazily slide her moistened finger up and down her open slit.
Kjem shifted uncomfortably in the constraint of his boxers as his dick grew.
Lisa held her wet finger still, vertically in her slit and against her clit, and started rocking her hips into it. After a short while of this, she moved her finger tip in and out in time with her increasingly deep rocking, so that it entered her just a bit with each stroke.
Kjem's boxers did little to hide the fact that he was now fully erect. One of the students turned to say something to Lisa, but Lisa expertly whisked the one side of her smock back over her lap.
"Stay focused, everyone," Lisa told the class.
"I was just going to ask if I could move closer for some detail work," asked the student who had wanted to talk to Lisa.
"Sure, in fact why don't you all move up, just make sure you don't block each other," Lisa replied. "And while we're at it, it looks like Camila, our female model, is here"
Camila walked in from the dressing rooms, wearing a very small orange thong-like bikini bottom and a very thin white "Hooters" tank top cut off high enough to show some underboob. Some of the students laughed, and someone said, "Take his dessert order!"
Camila laughed, perhaps a bit nervously, and Lisa walked to the front to arrange the two of them on the couch. She sat Kjem up in a seated position, legs apart (much to the apparent approval of the audience), then stood Camila directly in front of him, facing him, and pushed her right up between his legs.
"OK, Kjem, now reach around and grab her ass cheeks with both hands. Good. Now pull her cheeks apart. Camila, arch you butt out."
Lisa reached between them, and gathered and pulled at the front of Camila's bottoms so that they came up all the way between her pussy lips. "Now hold this position," she told them, as she adjusted Camila's arm and head positions.
After a few minutes of student work, Lisa asked if they were ready to move on, and got a series of "yes"s.
"OK, now let me show you how important authenticity is in modeling," Lisa told the students. "Camila, get on your knees, and put your head in Kjem's lap," she told her, and then arranged her hair around Kjem's lap so the students couldn't see. She made some further adjustments, making sure Camila's ass was pushed out for the audience to see clearly. The string of her thong bottom sank deeper into her slit, exposing her wet inner lips. Lisa then let the students sketch for a few minutes.
"OK, now let's see if there's a difference if we do it this way," Lisa told the students, then pulled Camila's hair aside and, hidden from the students, pulled Kjem's dick out of his boxers. She eyed Camila, who knew what to do, and she engulfed Kjem dick in her mouth. Lisa put Camila's hair back over them to hide their activity and stepped away.
"Now, see any difference?" she asked the students. Kjem hadn't moved, but his shoulders tensed, and his eyes rolled back. Camila didn't bob, or move at all as far as the student could see, but she mouthed and tongued Kjem's dick with abandon.
"As you can see," Lisa told the students as they worked, "you can easily pick out the difference between simulated action and the real thing. So, when you're working with models, be real, otherwise it just isn't going to come out right."
Camila's head started to bob gently, and Lisa let things go for a while as the students worked, until Camila's juices started to run down her leg.
"Well, that's enough of that," Lisa told them as she came forward, and pulled Camila away from Kjem. Kjem struggled, not entirely successfully, to put himself together before he was exposed to the class.
Lisa stood Camila up and laid both of them down sideways on the couch, Kjem behind Camila. She pushed Kjem's upper hand up under Camila's shirt so that it grasped her breast, then adjusted Camila's shirt so that the students could see Kjem's hand but not her breast. Lisa, standing in front of them so that the students view was obscured, positioned Camila's upper knee into the air a bit, then pulled Kjem's dick out and lay it between Camila's legs, sliding his shaft between Camila's pussy lips. She dropped Camila's leg again, trapping Kjem (although he didn't realize it) with the tip of his dick exposed between Camila's legs.
Lisa stood back and let the students work a bit.
"Now, as you can see," Lisa continued, "in this artificial situation, the models are thinking about modeling instead of each other. Camila clearly isn't comfortable with that wedgie, and Kjem's dick is getting self-conscious and pulling back from view. Let's see what we can do about that, shall we?"
Lisa came forward again and untied the knot holding Camila's thong together, then opened her legs a bit and pulled and maneuvered the material to take it away. She slid Kjem's dick back between Camila's pussy lips, and closed her legs again.
"Not quite right yet," Lisa told the class, and then went down on her knees and spread Camila's legs a little more, then dove in to take Kjem's dick into her mouth. After half a minute of bobbing work, she pulled away, closing Camila's legs in the process. The head of Kjem's now very erect dick slid out between Camila's pussy lips.
"There, that's better. Camila, every little bit, rock you hips some to keep Mister Eager charged up," Lisa said, returning to her seat at the back of the class.
The students worked for a long while on some basic sketches and idea notes. Every couple of minutes Camila rocked her hips back and forth, sometimes using a free hand to push his dick deep into the groove between her pussy lips. She got increasingly red faced and Kjem could barely contain himself.
Camila eventually sent a look to Lisa, and Lisa nodded in return. Camila used her hand again to hold Kjem's dick up into her slot, rocked forward as far as she could go, and inserted his tip into the opening of her canal, and then rocked back, sliding his dick maybe half way into her. Kjem gasped in surprise and wonder, and Camila started rocking back and forth continuously, pushed his dick completely into her. Kjem responded with his own rocking motion, and before long they were fully into a deep fuck, the audience forgotten.
"There, now," Lisa whispered to the class. "See the huge difference when the models aren't modeling?"
After a while of this, Camila tightened up and arching her back into Kjem, shuddered and gasped in orgasm. Kjem was able to ride her writhing out, but when she started to relax, he too was taken over by the sensations and grasping Camila's breasts firmly, drove into her and spasmed his seed into her pussy. Camila turned her head as he was coming down, and kissed him cheek over and over, then turning back seemed to realize that she'd just been fucked, orgasmed, and been inseminated in a classroom in front of an audience; her face went bright red and she dropped her leg in a small effort at modesty. Kjem, coming out of his daze, also recognized their situation and also blushed heavily.
"Well," Lisa spoke out loud to the class. "That was nice. Don't hide...". She walked up the the coupled two, and gently lifted Camila's leg back up, revealing that Kjem was still inside her, but his semen was starting to leak out and run down her thigh. Camila turned, if possible, even redder. Lisa scooped up some of the white stuff from Camila in her finger and popped it into her mouth.
