Rico's body is warm below you,but it seems to be getting larger somehow. When you finally do pull away Rico is a good deal more muscular and taller than you. You find yourself staring at a cock at least a foot long and dripping from the cum it just sprayed.
"Go on, now suck!"
You've never sucked before, and you're not sure you can now with it being so long, but Rico forces your face onto his huge dick. You can't seem to resist at all and, as the dick goes into your mouth, you feel your mouth grow longer to accommodate it. You can't help but lick it with your tongue. It doesn't take much to set him off and you feel his cum going warm down your throat. It feels so good, you can't stop sucking even as you notice Rico's body becoming hairier and more and more muscular. Your own body feels strangely soft and weak. Your stomach seems to fill with the cum pouring in your muzzle/mouth. Before long Rico has become a minotaur, a gigantic primal beast whose cock seems continuously loaded.
You start rubbing your own cock, but while it gets hard you can't seem to cum. It actually seems to get larger and wider as you rub. You feel an odd sensation as the tip reaches your belly button and seems to merge into it! Then you feel it grow out, softening. Your perfect six pack is not just merging with your dick but turning into a sagging gut! You can't look down to see what's going on, but as you drink in Rico's cum you feel yourself softening, enlarging, and then you feel small, pleasurable bumps on your soft gut - utters?!
A strange sensation comes as your backbone extends and you feel a tail growing out. You can no longer feel your feet. and your hands seem to be changing strangely - you only have two fingers on each hand and a thumb.
Finally Rico seems satisfied and goes to sleep. You rush to a mirror. In it you see a horrific site. You are now a cow-boy, literally. You have soft moobs and a large utter with what appears to be six penises on it! Your body is now pear-shaped but your skin is still flesh, though there are vague hints of darker spots on it. Your face is very long and cow-like. Unable to take it any longer, you faint.
In the morning you wake up next to Rico. Both of you seem to be back to normal, though your dick feels a little sore. You leave quickly and get back home, figuring it was all a strange dream. There is one message on your answering machine.
"Enjoy yourself again Jake? I think you've seen just the first stage of the curse. You see, I figure you like meaningless sex so much I'd make you into a sex machine. Eventually the changes will go further and become more permanent. You'll stay male, but become a mindless sex cow eager to suck other guys dicks and get milked. At least, until you learn to change. Of course you'd need to learn that before your mind goes. Oh, and any guy you have sex with will always change into a minotaur that won't stop cumming until you reach a fully changed form. And if you're thinking of giving up sex you'll find yourself unable to stop until you finally want a meaningful relationship rather than a one night stand. Actually you won't remember any of this, except the one way to break the curse is to find true love." Immediately after that is gibberish.
You look blankly at the answering machine. No new messages, except the guy from a couple nights ago telling you you need to find a 'meaningful relationship'. Ha! Not you, not Jake. You've got a perfect bod and a perfect dick and you intend to use them!
