Sex-Ed with assistant

John and Lena, now in his clothes, were presented to the class. John was confused because no one laughed. "Now we will demonstrate how to bring a human to a fulfilling orgasm", said the professor.

No time to think about that sentence, John was suddenly grabbed and hed by his arms by the two assistants. "What? Let me go". John began to demonstrate when suddenly a needle went into his body. His arms stiffened and he could not move a muscle.

"The male G-spot is in the ass, my assistant will now demonstrate how to pleasure it" - The now naked assistant began to handle your body like a mannequin and put you in a cowgirl-Position on top of him. "Help! Somebody help!" - John screamed, but nobody answered his call. The assistant ripped apart Johns pantyhose and he slid his panties to the side. "Noooo, please no". Lube was placed onto Johns asshole.

John was held up by the other assistant. His asshole was right above the cock of assistant 1. John was shoved down on the thick rot and he screamed out in pain. His asshole was then violated by multiple thrusts. John began to heat up because of the constant pressure on his prostata. He began to moan unvoluntarily like a girl so that he could not hear the professor anymore. After 20 minutes the assistant came in Johns ass. John felt the warm liquid pouring inside of him. "And then we shut the hole with a plug" - The professor shoved a butt-plug in Johns ass, put the panties in their place and brought out a new pantyhose which was put on John. "You can practice on this student after class". John was in agony, as he heard this words. This will be a long day.
