"You know, boys, I think I have an idea," Dave said after hours of groping, kissing, nuzzling and licking. You four Barbie Boys were lying on your king-sized bed, all naked, showing your perfect plastic bodies and your penisless groins.
"Tell me more, sweetie," Jason said in his smooth, effeminate voice.
"Well, you know I'm in a frat, right? Well, tonight we are having a small party, and it's bros only. What if I spike the punch bowl with a couple of smoothies?" My eyes shine as I slap Dave's perky ass cheek, eliciting a lustful moan from his mouth.
"That's an awesome idea! We need to spread our condition to all the sexy guys we can find. Being a Barbie boy is the best!" I say, caressing my crotch and enjoying the sensation of fucking and being fucked at the same time, forever.
"Let's go to the supermarket, then!" Steve exclaimed.
A couple hours later, you, Steve and Jason are hidden in the bushes outside Dave's frat house, waiting with bated breath. The party has just started, and nineteen bros (Dave included) are enjoying some snacks, bragging about all the chicks they banged (not for long, you think with a smirk) and drinking from the tainted punch bowl.
It doesn't take much longer for the first plastic dick to fall on the floor. Dustin, a tall, dorky guy with glasses and curly hair, takes off his t-shirt just in time to see his chest become nippleless. He moans and pants in a corner as soft plastic replaces his skin, smoothing down his features in a boyish, twinky, adorable look. Gazing from the window, you can see the change in his eyes, as he forgets girls completely. He now only lives for other Barbie boys like him.
Next to him there's Jay, a black, muscular frat guy whose erect cock is now rolling on the floor in front of him like an oversized dildo. Dustin grabs him with a delighted grin on his face and shoves it up his own ass, moaning like a bitch in heat as the black cock merges permanently with his ass. Jay just lets out a confused, but horny sigh as Dustin the Barbie boy grabs his own plastic penis and pierces the black bro's virgin asshole, sealing his changes once and for all.
