You take an extra step in, allowing Charlie to enter the bathroom behind you. "What are you doing here, Charlie?" you ask, a smile creeping on your face as he shuts the door.
With an innocent smile and light freckles on his face, Charlie is a naive and happy-go-lucky sorta guy. Well liked by the team, but a little slow on the intellectual and social front, it's no wonder your sex appeal and charm alerted him to you. You could sense that Charlie isn't normally gay, but one who easily lets his sexual intuitions get the best of him without him even knowing it. He examines you in Patrick's body. "Something's different about you, man," he says, staring at your twitching package underneath the jock, "you look...really good..."
"You like what you see?" you ask. "would you like in on some of this bod?" Patrick looks up puzzled. He does want Patrick's body, but he's not sure how. "See how it looks," you command, hand running across your crotch.
Charlie takes a step forward and places his hands on the bands of the strap, pulling them down around your legs and to your feet. At the moment of nudity you allow your cock to grow, hitting him in the forehead. Charlie stares in admiration as it grows, but his lust lies not in an act of unity but in the gaining of Patrick's body, of his stature. "Drink, and it's your's," you say.
As Charlie wraps his mouth around you you melt in extacy and decide how you want your seed to transform Charlie.
