This happened to me 5 years ago.... I was 19 years old at the time.
I had been cross dressing on and off privately through highschool. Mostly trying on panties and lipstick and picturing myself as the girl in getting fucked while watching porn...
On a lazy summer afternoon I was doing my usual routine, jerking off in some lace panties... when i finished I cleaned up and went out to the bar with some friends... still having some girly thoughts in my head.
