jerkin off anywhere is so easy, if ur in another building besides your own, go to a stall, if ur in bed at home or whatever, just grab a sock and stick it in the dirty laundry after ward, I use socks constantly. haha keep weird ones that dont match specifically for the purpose too, my jerkin socks, jerk into the sock, wipe up and throw into the sack lickety split. I always hated using up too much time on jerkin, and clean up, its a waste. With a sock it takes about 3 seconds, its AWESOME
