You wait until dark

You finger yourself on the floor of the classroom. Your joints become sore from the hard tiles, so you roll over onto your back, but your fingers never leave your pussy. With your dirty thoughts, eager fingers, and relentless pleasure from the implant, it doesn't take long for you to orgasm hard, pussy walls clamping down on your fingers. Your juices drip down the inside of your thigh to the floor and, unable to resist, you begin your ministrations again, cumming not long after.

Hours drift by as you play with your sore cunt. To mix things up, you roll back over, sit against the wall, hump the leg of a desk. You like to imagine that you're being asked to do all of these depraved things. On an impulse, you lick your fingers clean because that feels like something Patrick might ask you to do.

You finger yourself so long that your hands begin to cramp and, stopping to take a break, you realize that it's after dark! Shaking yourself out of your horny haze, you see that the light from the windows has dimmed, and there's no more light from the door. Risking a peek, you hobble to the door and crack it open to find the hall lights are off. No one is around. You sigh in relief as your legs tremble from exhaustion.
