Despite my girlfriend being on her period, I cheated on her. I told myself it was because we couldn't have sex, but even I didn't believe that excuse. Before I knew it, she flew into a furious rage, screaming, "You cheated while I was in pain and suffering?! That's unforgivable! You'll just do it again next month anyway!" To calm her anger and ensure I couldn't cheat with another woman during her menstruation for a full week, I was forced to have my semen completely drained by her mouth pussy—every single drop. There was no time to accumulate any sperm at all. Even after one ejaculation, she relentlessly continued with aggressive blowjobs. "Make sure you shoot everything inside my mouth," she demanded, then swallowed every last drop of my cum with utter devotion. A staggering 15 rounds of intense, deep-throat swallowing ensue, delivering a shocking sex scene where I surrender everything to her powerful oral mastery.
