If after you masturbate, you piss after you use those tissues, use another tissue to rub the backwash off, then change your pants and underwear, then get into a girls bed but she's not in there. And then she probably uses the bed naked later on when you're not in it
you masturbate, flush the toilet, then a girl comes in and takes a dump so big it makes water splash on her vagina
if you get a full erection in a hot tub full of girls before you get kicked out by them
if you take a shower after you masturbate and rub the soap on your pelvis and she uses the soap on her vagina
if you take a shower after you masturbate and rub the soap on your penis and she uses the soap on her vagina
if you take a shower after you masturbate, didn't use soap at all, went out, used a towel, and didn't throw the towel in the hamper, and she used it on her vagina
if you take a shower after you masturbate, some cum got on your leg or something, didn't use soap at all, went out, used a towel, and didn't throw the towel in the hamper, and she used it on her vagina
i always throw the towel in the hamper afterward just in case
