It's clear your girlfriend is upset by the way she is redressing. You came in just one thrust, and her resentment and frustration finally reaches it's boiling point. As she redresses, she tells you just how sick she is of it, and how unsatisfied she is. It's a sore spot for you, but it doesn't matter. She continues to verbally degrade you, telling you that you aren't even a real man, that a woman like her needs to really be fucked in a while. "It's not MY fault you're a premie loser!" Annoyed and bitchy, she keeps digging into you for your premature ejaculation issues until she finally gets tired.
