She transforms Nick

You stand there, naked, staring at Nick. You're shocked by what Kelly is suggesting.

"You... want to have a threesome?" Nick asks. You're glad he did, because you were about to ask the same question.

"I mean, why not?" Kelly asks. "You two know each other, Andy's clearly dying to fuck. Let's do it!" You want to deny what Kelly said about you, but you really can't, you are extremely horny. You never thought you' be in this kind of situation with Nick, but the two of you get along pretty well, would this really be that weird"

"Okay!" Nick quickly responds. You are a bit surprised by his eager response. "I mean... if that's cool with you, Andy"

You're not sure how you should respond, but the fact that everyone else is on board, makes you want to go along with it.

"Yeah... sure." You say hesitantly. You look over at Kelly to see her grinning.

"Great!" she says "But I should let you know, I'm not into fucking two guys at the same time. I want my first spit roasting to be special."

"What do you mean?" You ask confused.

Kelly simply smiles as she moves in closer to Nick, once again embracing him in a deep kiss. She begins leading him towards the bed, keeping her lips locked with his. You watch, starting to feel a bit neglected, as the two collapse on your bed, with Kelly laying on top. She finally breaks the kiss and leans back, straddling Nick with her legs. You think you hear her mumbling something, but can't be sure. She suddenly slides off of your roommate and gets off the bed. She moves back over to you, wrapping you in her arms.

"It's always fun to watch." She says to you.

You're very confused as to what she means. Nick seems a bit confused as well, as he sits up to look at the two of you. You quickly notice something strange, his face starts to look slightly different, like it's getting thinner, You look more closely to see what seems to be his lips getting a bit bigger, more plump. You move your glance down from his face to his chest, which now seems to be expanding. You quickly turn back to Kelly to see her looking on with a huge grin.

"What the hell?!?!" Nick shouts, suddenly realizing his changing chest. He frantically yanks off his shirt to get a better look. "Are those tits!?!?!"

You can clearly see that they are. You gulp as you watch the two new, large, perfectly shaped orbs hanging off of nicks chest.

"If you're surprised by that, wait till you take off your pants." Kelly says playfully. You can tell she's enjoying this, clearly it's nowhere near as shocking to her as it is to you and Nick.

Nick frantically pulls off his pants. He looks down in horror as instead of a dick, (Which you assume is normally there, you've never actually seen it.) there is pink, puffy, vagina between his legs.

"What's happening?" He shouts. His voice is now smoother and higher pitched.

"You're becoming sexy." Kelly says. She's not wrong. As the changes seem to finish, it no longer feels like your staring at your roommate, but an extremely attractive, naked, woman.

"How?... Why?" Nick yelps, clearly too much in shock to ask deeper any deeper questions.

"Oh right, I guess I should introduce myself." Kelly says. "My name's Kelly, I'm a witch." She holds out her hand but Nick doesn't move. "We needed another sexy woman for this threesome, so here you are. I'd go by Nicole now if I were you, but it's your call." Kelly eventually gives up on the handshake, and brings her arm back to her side. She turns back towards you. "So, shall we get this fuck party started?"

You stare at... Nicole? As she stares back at you, both of you possessing a baffled expression. This all seems wrong, but as you take another look at your excruciatingly hard cock, it might not be the craziest idea.
