I kind of figured my sister masturbated. Although we have always been very close, I never knew for sure.
One evening just after Christmas when I was home from college, I was feeling quite horny and thinking about retiring to my room to masturbate. My sister and I were watching The Last Nimsy, a fun movie we had seen before. Our parents were out shopping or something.
Without thinking it through, I suddenly asked her, “Do you masturbate?”
“Of course,” she said, and turned back to the TV.
We watched in silence for a while. Then she asked, “And you?”
“Hell yes,” I volunteered, perhaps more quickly and brightly than I intended. “In fact, I think I’ll go to my room and do it now.”
What she said next was the last thing in the world I would have expected: “May I join you?”
Within 5 minutes, we were both naked and laying on my bed. We didn’t touch each other. We didn’t kiss or anything like that. I guess, being brother and sister, that somehow seemed icky to both of us. But masturbating side by side – somehow that was OK. I have to admit I was hard as a rock. Having her see me in that condition was embarrassing, and yet I was also proud and glad she was staring right at me.
We started masturbating. I was working hard on not cumming too soon. What a view! I have to say my sister is a looker. This was not the first time I had seen tits, but the first time they weren’t on a screen. This was the real deal. And her vagina, and ass? Oh wow!
She was the first to do what I had only imagined: She reached out and gingerly touched my thigh. When I went “umm” and didn’t pull away, she started gently examining my balls with her fingertips.
I’d like to tell you that she went on to give me the world’s best handjob, but the truth is cum started shooting out of my penis right away. She hadn’t touched my dick at all. It was the fastest, strongest orgasm I had ever had. Not only that, but it was my first ever hands-free orgasm, in fact the only hands-free orgasm I’ve ever had.
I was immediately freaked out. So was she. We put our clothes back on, went silently back to the movie, and never spoke of it again, and that was 5 years ago.
