I cheated on her while she was on her period! (Because I couldn't have sex...) I thought she wouldn't find out, but... You cheated on me while I was suffering from a stomach ache?! That's impossible! You're going to do it again this month! During her menstrual period for a week, she was with another woman. Every drop of sperm is squeezed out with her mouth and pussy so that she can't cheat! There's no time to accumulate sperm! Even if you ejaculate once, follow up blowjob thoroughly!
