The experiment continues

The boys closed in around Julie, spreading her legs wider, their hands and mouths causing her mind to go numb in sensation. Mr. Marquard returned to Julie’s side, holding a few items.

“A young girl's pussy can be very tight, but once they have reached a certain point of arousal, it can take almost anything: Mr. Marquard explained as he spread Julie’s pussy lips and inserted a plastic test tube into her. Julie breathed in sharply, her back arching off of the desk. Mr. Marquard started sliding the tube in and out of Julie’s increasingly wet hole, noting graphically how her pussy gripped it. All the boys stared intently at her exposed hole, and Mark was imagining how hard her pussy could grip his dick.

“You can tell Julie must be a virgin, but she has definitely experimented sexually before,” he said as he smiled at Julie. Her only response was to try to steady her breathing and calm down. Mr. Marquard removed the test tube, causing Julie’s pussy to remain open for a few seconds before tightening up again.

As Julie relaxed onto the desk, Mr. Marquard firmly grasped her left tit and quickly fastened a clothespin to her nipple. “Ouch!” Julie cried out as she tried to lift herself off of the desk. “The pain will subside soon” Mr. Marquard chided her as he used one hand to press her back down onto the desk and with the other he fastened a clothespin to her other nipple. “Many women like bondage, or slight pain, it can cause mild to **** arousal,” Mr. Marquard explained. “See how Julie’s nipples are engorging into a deep burgundy color?” Julie could not believe that she was actually being turned on by not only her teacher, but also in front of her fellow classmates.

Mark, feeling suddenly bold says “Julie, does having your nipple pinched feel good?” Shocked at Marks blatant question, Julie turns a bright shade of red. “Well Julie, this is supposed to be a learning experience, does having your nipples pinched hard arouse you?” Mr. Marquard prods her to answer. “y-y-eess” she responded shakily.

At this the boys can hardly contain themselves, all of them dying to get their cocks somehow in Julie. Mr. Marquard also has a raging hard on, and helps Julie off of the desk. “Julie, I want you to get on your knees and suck off every student and myself here.” Julie is surrounded by the male students and Mr. Marquard, and decides she should be compliant. She slowly lowers herself to her knees, eyes downcast. The boys look nervously to one another, when Mark steps up and quickly undid his pants and lets them and his boxers fall to his ankles. The sight of a hard cock in her face gets Julie immediately in the mood, and unleashes the sexual animal in her. She opens her mouth wide and starts bobbing on Marks dick.

Another boy steps up, with his dick already out, places Julie’s hand around it, and she quickly starts pumping his shaft. Mark starts meeting her thrusts, feeling her tongue circle around his head, and then sliding its way down to the base, over and over again. Julie starts jerking faster on the dick in her hand, and he finally grunts and blows his load onto her exposed tits. Quickly, another boy replaces him, and another one steps up to her other hand. Mark, still thrusting into Julie’s mouth, looks down to see she is looking up to him, and his cock disappearing quickly into her mouth. He can’t hold it any longer, grabs her head with both hands and gives a final thrust, blowing a thick load of cum down Julie’s throat. He steps back, to catch his breath, and watches as the rest of the boys and finally Mr. Marquard get their satisfaction from Julie.

Once the boys are through they all quickly file out of the room, and Mr. Marquard helps Julie to her feet and straighten herself up before handing her back her vibrator. “You did wonderfully, Julie,” he said with a grin. “I’ll keep you in mind for future lessons.”
