"Shall I help you lose your virginity?" Out of the blue, my step-sister (a gyaru) offered to teach me about sex! I thought it would be a sweet memory in her warm, inviting vagina, but then she surprised me by saying, "Do you know what we're going to do next?" and suddenly gave me a lesson in multiple ejaculations! It's mean to train me as her sexual outlet, but the experience of losing my virginity was surprisingly pleasurable...
