Grab her pigtails and pull her head back so she can’t move. Force your cock up her dirty little teenage ass. It’s not like someone this size can do anything about it, anyway.
When they’re this petite their throats are almost as tight as their assholes, and she needs to learn to go ass to mouth.
Piss in her throat and eyes and gag her to tears, rape her ass some more, cover her face in cum and piss, then send her home to her parents.
