It seems you were right in guessing she was inexperienced and vulnerable. The fact that she was keeping out of peoples way and hugging the walls only made things easyer. You walk alongside some other students (getting a couple of nods of acknowledgement from some important looking babes it seems news of your somewhat famous meals demise has spread around your house already) then as you pass her you simply dive on her using your much grater straight to clasp a hand over her mouth and drag her through the closest door to somewhere private.
The door you chose turns out to be for some sort of stoor cupboard, you frow her against the (not very)far wall, flip the light switch and stare into her wonderfull eyes. She looks terrified but doesn’t try screaming for help as you grab hold of her boobs and start ripping her cloves off.
With a few ruff tugs you get her down to her underwear and a few ripped shreds of shirt, she starts begging with you telling you she’ll do anything you want if you spair her and desperately flutters her eyes while doing the blowjob mime with her hand and mouth.
