We've been dating for almost two years. However, we still don't have a physical relationship. As for me, I'm a virgin who has never seen a naked woman in my life. I mustered up the courage to take off her clothes, thinking that today would be the day, and when I revealed her huge G-cup breasts and firm, beautiful ass, my mind went blank and I was frozen. My first time having sex was completely female-initiated. She straddled me, thrusting my dick into her, raising her voice and swinging her hips lasciviously...By the time I realized it, I had ejaculated. I felt pathetic and didn't know what face to make to her. She held my hand and smiled, saying, "I think you should laugh."
