When I'm surfing porn and of course masturbating at the same time, I sometimes like to make a bet with myself. For example, I have to make myself cum on the tenth pic showing a girl with two dicks inside her. Or I'll have to bring myself to an orgasm when I see a girl with glasses covered in cum. It can be very exciting to have a cum trigger like that. Does anybody do that too? And what are your favourite cum triggers?
