Semen Shuttle

Rocketed from the scrotum in speeds that break the sound barrier. It gets stuck in hair, ruins bed sheets, whitens teeth, causes lazy eye, and in some cases my force you to pay monthly child support checks.

Last night this girl was giving me a plumbkin so I decided to blast my semen shuttle right into her eye.

My friends and I are all on the struggle shuttle today from a very long night of partying.
