What the two didn't notice was that while they were busy fucking a few others had come into the showers and seen Sean's pussy being fucked. Intrigued they started walking towards the two fuck buddies to see if they could get in in the action, by their standards Sean wasn't male as he didn't have a dick, he had a pussy. One of them taps the guy currently holding Sean up and says "mind if we cut in?" gesturing to himself and his buddies
He shrugs "Sure, go ahead. I'm done with the whore anyway." he leers at Sean one last time before stepping back and going to take an actual shower
Sean too tired from his first female orgasm makes no move to protest, he simply moans as the others move in, there's at least 6 in total. The first one who originally asked if him and his buddies could get in on the action goes first and grabs Sean and pins him against the wall once more by holding his arms above his head. Wasting no time he quickly sheathes his dick inside Sean's pussy and starts thrusting while Sean only moans as he was bigger than the last one, not big enough to hurt but enough to be slightly uncomfortable. Soon enough he's finished emptying his sperm inside of Sean and the next one steps up to take his place, this continues until they're all satisfied and Sean is just laying there where he was left against the wall too tired and spent looking completely fucked out covered in cum and moaning wantonly.
What Sean didn't know was that his body was going to change even more to resemble a female's the more he was ducked and the more estrogen was released into his system. Eventually he unsteadily gets back up on his feet leaning against the wall for support and goes to shower all the cum and the smell of sex off of him before going back home.
