Turns your cock into a living dildo

Erica gestures to the redhead. "Amy, you have the stuff I asked you to bring?" Amy nods, and reaches into a small bag near her seat. "Of course, what do you want?" Erica looks at two more of the girls. "Cuff her to that couch leg." You tense up, but in your current state, you have no will to resist. Amy passes a pair of handcuffs to the girls and helps them pull you back to the couch. You don't struggle much until they wrest your hands away from your cock. You cry out, "No please! Let me touch- let me..." The girls giggle at your cries, but don't hold back, pulling your hands around the leg of the couch. They loop the cuffs through some part of the couch frame and cuff your wrists together. Moaning helplessly, you try to rub your cock between your thighs to no avail.

As she taps on her phone, Erica asks the group, "Remember that game we used to play when we were first-years? When we got super drunk?" One of the girls replies, "You mean when we'd pass that dildo around and see who could take the most of it in their mouth?" Erica turns to the girl, "Exactly." She taps a final button on her phone and you get a strange feeling in your crotch. A soft *thud* is heard and everyone looks down at your dick, which has now fallen off your body. You're too shocked to react and look in horror at the smooth, hairless skin that covers where your dick used to be. Strangely, the pulsing sensation hasn't gone away, and you see your swollen dick throbbing on the ground.

The other girls watch in awe and fascination as Erica walks up to you and picks up your cock and balls. You feel her hands wrap around it, lift it off the floor, and bring it to her mouth where she gives it a tiny kiss. You shiver involuntarily. She turns to the room. "As Alex has probably found out by now, the implant is transmitting the sensations back to her body wirelessly. I have no idea how it works, but..." she punctuates her sentence by running her warm tongue up the entire length of your shaft. You can't help but cry out at the feeling and moan wordlessly.

"So... who wants the first go?"
