jake was your average teenage guy. he liked watching porn and playing videogames the only interesting thing about him was his above average cock which was 8 inches when soft and 12 inches when erect.
in all honesty his sex-ed class was boring he spent most of his time in class looking at some of the hot girls and laughing at the occasional cock joke but never really payed attention to class that was until today
when he walked into class he saw that the tables now had assigned seating. everyone was at a table with someone of the opposite gender. he didnt see or care who sat down at his table with him he then heard the teacher talking except it wasnt the usual this how the ovaries work and this is why girls have boobs and this is what a condom is nonsense his teacher instead said
"due to certain circumstances (*she whispers under her breath* involving the government) our school has been chosen to take part in a genetic engineering experiment having to do with gender"
"for this experiment you will swap sexual body parts with the person next to you. by this i mean males will grow the breasts and pussy of the female next to them and females will grow the penis of the male next to them."
"oh and one last thing. this change is for the entire school year."
you immediately look over st whos sitting at your table and see
