I was at a drinking party with my older brother's friends when I first ended up in a sexual relationship with someone I met by chance. My older brother was having sex with another friend in the next room. Everyone loves sex so much that it's hard to resist. Maybe that's why I didn't feel much hesitation coming here today. I can sense a little excitement waiting for me, and my excitement is building up. Of course, I'm nervous, but that only adds to the erotic thrill. When I masturbate, I usually lie down with my legs spread in a wide M shape, watching dirty videos on my smartphone with one hand. Sometimes I let out a little moan without realizing it. I've always been sensitive and disliked clitoral stimulation, but today I'm willing to push through and let him explore me thoroughly.
