Sophie 2 grows a cock upon orgasming

As the tremors of orgasm run up Sophie 2's body, she feels a sudden burst of expansion in her clit. It engorges and elongates until it's turned distinctly into a penis. The both of you gawk at it for a moment, unsure whether it's actually even functional, until a post-orgasm spasm spurts out a small dribble of precum from it.

Sophie 1: "Neat! I won't need men at all anymore."

Sophie 2: "H-how did this happen?"

Sophie 1: "I'm guessing that happened directly in response to your orgasm."

Sophie 2: "Duh, but why did it give me a cock?"

Sophie 1: "For starters, this'll make fucking you a lot easier."

Sophie 2: "Excuse you, miss main character, but I believe I'm the one who's going to be doing the fucking around here."

Sophie 1: "Now where did that cockiness spring up from?"

Sophie 2: "My loins."

You and your clone start tussling for the rights to be on top. Sophie 2 doesn't have much of any physical advantage over you, but her cock is an extra appendage to be wary of. If she gets to insert it, she'll have all sorts of wild and outdated ideas about gender roles. She's going to make you wear a dress and cook for her, while she lounges on the couch drinking beer! You shan't let that happen.
