You lose control

You put your pencil to paper and start to write an answer to the next question. Another pulse of pleasure in your pussy catches you by surprise, and you moan and tense up. Grinding your legs together, you don't realize how hard you're pressing down and the tip of your pencil snaps. Maybe the implant is messing with your head, but you can't take this any more.

"Fuck it," you say, and you push your chair back abruptly, unzip your jeans, and stuff your hand down your panties. As soon as you make contact with your pussy lips, you moan loudly in ecstasy and start rubbing your clit. Around you, your classmates look at you in shock. Many gasp or shout in surprise, but you barely register their reactions. Your legs start bucking as you finger yourself to an orgasm. "Ung F-FUUCK" you cry out, clenching your legs around your wrist. Your other hand snakes its way under your shirt and bra to pinch and pull at your nipples as you ride the wave of the most intense climax you can imagine.

Numbly, you start to come to, realizing that you passed out for a second or two. Looking around, you start to recognize the looks of shock, horror, and fascination on the faces of the other students. The pleasure keeps pulsing in your cunt, and you can't help yourself from circling your fingers softly around your pussy lips, moaning as you do.
