You sadly trudge from your girlfriend's house to school, and get in the door with a couple of minutes to spare. Joining the 'induction queue', as they euphemistically call the queue to have the changes done to your body, you try to distract yourself from the inevitable, browsing your phone to pass the time and hoping no one gets mad at you for it.
Once you're called through, you enter a sterile-looking white walled chamber with a seat in the middle of the room and a projector screen. The screen has a message on it styled like a PowerPoint reading, "PLEASE UNDRESS". Great, as if this wasn't uncomfortable enough knowing what you were gonna have done to you. Sighing, you pull off your uniform, step out of your boxers and sit naked on the seat.
The message on the screen changes to say, "PHASE 1: PURGING". You're about to question what 'purging' is supposed to mean, but then a weird tube slides down and settles around your cock. Despite having fucked less than an hour ago, you quickly get hard again. This thing seems to constrict around your shaft in a really pleasurable way, like some kind of fleshlight. It sucks on you and your hips involuntarily thrust up at it, feeling so fucking good. You pant and keep thrusting at it harder and harder, until eventually you cum hard inside it. It sucks on you and you groan. It feels like it's trying to milk you dry, and when it finally pulls away, your cock feels spent, even though you're still horny as fuck.
