During their hour of detention, Paul Delay, Enzo Lemercier and Gabriel Lambert expect to copy lines but their biology teacher, more perverse than ever, improvises a practical course of anatomy before inflicting them a punishment from another time.

The innocent Gabriel Lambert is called to undress in front of his hilarious classmates to be used as an anatomical model in a true feat of exhibition. The high school student embarrassed by this unexpected situation shyly takes off his shirt but his teacher expects more. Gabriel blushes again and tries to argue when Mr. Marguet joining the gesture to the word drops down his pants and his underwear. The young man is now completely naked in front of his class and his teacher begins to describe his anatomy. M. Marguet gently pulls back the foreskin of Gabriel and explains the function of the glans before seeing that seminal fluid flows from the student’s urethra who’s apparently as embarrassed as he is excited by the situation. Gabriel cannot hide his erection and Mr. Marguet who was waiting for it starts to masturbate him slowly and making the student’s cock growing in his hand. Enzo and Paul are captivated by the experience and cannot resist to slip a hand in their pants.

The teacher is now shirtless and masturbating his student while his two friends are jacking off each other. But don’t forget this is an hour of detention and that before having fun the goal is to punish these insolents! Doryann Marguet then invites the three boys to face the blackboard, pants down and he distributes violent spankings. The three small asses blush quickly and Mr. Marguet then grab a metal ruler to continue his punishment. The three twinks that the pain seems to excite, seeing how their cocks are hard, count the blows while their teacher take of his belt to whip them again. After this well-deserved correction Doryann Marguet decides to test the oral skills of his students.

From this moment it’s a real orgy that takes place in the classroom in which everyone sucks and caresses each other before forming two exhib-voyeurs couples who will fuck side by side before exchanging their partners. Gabriel gets pounded hard by Doryann while Paul is tasting Enzo’s cock. The roles are then reversed and Gabriel rides Enzo while Doryann takes care of the ass of his favorite boy. When the excitement rise to the highest it’s the angel face of Gabriel which’s chosen to receive the boiling sperm of his three partners before to cum in turn several powerful jets on his belly.
