i used to cut the pocket out of my blue jeans,lube my dick up and walk around with my hands in my pocket.Thats all it would look like to a passerby but in reality i was stoking my cock while walking behind hot girls and staring at thier asses,sometimes id walk towards them,let my eyes burn into thier crotch then meet thier eyes thn right back tothier crotch and id make absolutely sure the saw my hand moving and my orgasm face and that thy knew i just came from staring at thier crotch!
