True sex stories: My sister Terri

Author: MrTony

Growing up, I often played games with my sisters, Vickie and Terri. I was 14, Vickie was 12, and Terri might have been 10.

For Terri, her favorite game was wrestling. Lately, I had noticed that when I wrestled with her she would usually give up and intentionally lose after just a few minutes. It usually went the same way – we would wrestle for a few minutes while I tried to pin her down, then she would seem to give up on wrestling and hug me tightly with her legs wrapped around my thigh.

Sometimes, I would remind her that she was supposed to be trying to get away. But, although I had often stopped playing by then, she would instead wrap her legs more tightly around my thigh and pull me closer, occasionally gasping as she repeatedly used her legs to pull her body into mine. I’d noticed that Terri would gaze into my eyes as her face grew more flushed and her legs wrapped more tightly around me, only averting her eyes from mine when she got a faraway look.

Usually Terri would bury her face in my shoulder and hug me most tightly as she pushed her body to re-clamp my thigh. Other times, if I happened to have her arms pinned over her head, she would just turn her head to the side. In those cases I’d watch her grow more flushed as her outward expression changed from intensity to relief. But I hadn’t understood why she went from bucking wildly, to desperately hugging me, to a relaxed, flushed glow.

But, as I thought about how a woman having sex was supposed to look, I finally realized that Terri had been orgasming. And I was surprised because I hadn’t expected that she would have incestuous orgasms with her own brother. She was hiding her face because I was her brother, and she didn’t want me to see how much she wanted me. Terri had probably orgasmed more than 20 times with me before I figured out what was really going on.

So, realizing this, I found my sister and I asked her if she wanted to wrestle.

Want to Wrestle?

So I asked Terri if she wanted to wrestle. She said “yes” almost before I could finish asking the question. She asked “Here?” pointing to the floor beside her, and I nodded. So she knelt down on the carpeted floor so that we could start wrestling. Before long, she was on her back. She pretended to be trying to escape for a bit, but not for long. Then, as usual, she wrapped her legs around my thigh. This was how we had often ended up. With one of my legs between her legs while her pelvis was pushing against my upper thigh.

This time though, as she moved her pelvis back and forth against my thigh I knew that she was getting closer and closer to an orgasm. I let her do that for a bit until I got the impression that she had lost control. Then I got my leg out of her grip and strategically positioned my body there instead. While I was hesitant to be so brash, my own desire had grown as I’d watched her increasing lust and loss of control.

So I slid my body down, trying to get my hard-on aligned with her pelvic bone over her cotton panties. My movement was both very awkward and very obvious — adjusting her position, and spreading her legs enough to position myself between her legs – basically getting her into the classic missionary position.

As I unabashedly forced my access to her pantied crotch, I was dumbfounded by her reaction – my sister helped to align her crotch with my hard-on and then eagerly spread her legs in the air as she began to rock her pelvis against the erection in my pants. She was ten, and I was fourteen, but to anyone watching, there was no mistaking what we were doing.

Still making a nominal effort to keep up the pretense of wrestling, I loosely held her wrists pinned over her head. But it was clear she wasn’t worried about the impression she was making – as she wantonly moved her pelvis back and forth against me. I helped by moving my body into hers in tempo. I’d exposed my undisguised, sexually lustful thoughts and that seemed to make all the difference for her own lust. Her pace immediately quickened and she looked into my eyes, clearly trying to get enough friction at the right spot. Growing frantic, her legs wrapped around me tightly, trying to pull me into her with a pace that matched hers. We were both out of control.

Any pretense of wrestling gone, it was my chance to be sexually assertive, so I released her hands from where they were “pinned” over her head and just timed my strokes against her very wet panties to match her motion. I knew her panties were wet because the front of my own pants were drenched from her juices. I knew that she would bury her head in my shoulder as she orgasmed, but I wanted to watch her at the crucial moment, which was arriving quickly, so I used one hand on her cheek to hold her head facing mine.

As she looked into my eyes, I could see her growing desperation. Her pelvis was arching into me now with an almost wild tempo, her breathing uneven. I was wearing very thin fabric pants, and I could feel the heat and moisture of my penis sliding between her engorged vaginal lips. I pushed my penis along her slit in a long stroke, hoping that she would feel it on her clitoris.

She involuntarily gasped, then flung her arms wildly around me and held me tightly – her eyes betraying the intense joy she was feeling. She arched her clitoris into me as I looked into her eyes, her long climax seemed to be amplified by knowing that it was me, her brother, doing this lewd act with her, and knowing that this time I intended this orgasm for her.

We Played and Played

Now that I understood the game, it became a ritual for perhaps a year. We probably played a couple of times a week, or whenever we could, never really talking about what we were really doing. And Terri’s “wrestling” time became a rush to position herself under me, wrap her legs around me, and thrust herself against me until she orgasmed.

I wouldn’t usually orgasm – but occasionally as I watched her climax I would get caught up in the excitement. On those occasions I would feel my penis shooting inside my pants as I stroked her while watching her – perhaps one out of every ten times we wrestled. Since I was orgasming while watching Terri orgasm, she never seemed fully aware of the effect she was having on me – that she had just made me ejaculate.

I would thrust against her as I was orgasming, sometimes gasping or at least a sharp intake of breath, but in the middle of her own wild thrusting I don’t think she ever noticed anything more than how my pants would sometimes be soaked through from all the semen I had squirted inside them.

Looking back, I sometimes imagine how Terri and I looked – my younger sister, skirt flipped up, legs open wide in the air, still in her panties, but doing her utmost to get her crotch mounted on my hard-on with each lunge. Me, fourteen and doing my part – wearing thin fabric pants that didn’t hide an erection for his sister, body positioned between her legs, sliding into her hard as she lunged against me, trying to get the right stroke at the right spot, the one that would make us both orgasm.

And it wasn’t unusual for my other sister, Vickie, to watch us “wrestle”. And since I also masturbated Vickie routinely, she knew exactly what we were doing. More than once Vickie watched as Terri and I orgasmed together. I think Vickie was really watching just to see if I would orgasm – she particularly seemed to like it when she saw me breathing hard then gasping as I pumped my penis against Terri’s panties. Sometimes I would masturbate Vickie immediately after, and she would orgasm quickly on those occasions. Other times I would masturbate Vickie first – Terri watching Vickie orgasm – sometimes Terri would move in close just to watch Vickie as she orgasmed.

I can still remember times when we had finished “wrestling” and Terri lay on the floor with her hands above her head, with a very contented look on her face. After she unwrapped her legs from around me, I would get up off her, looking down at her spread legs, with her skirt flipped up, and her panties drenched with wetness, the air smelling of sex.

Sliding my hard-on against her slit would mold her wet cotton panties so that I could clearly see her vagina, engorged lips, and enlarged clitoris as though she weren’t wearing any panties at all. A few times, her panties were drenched and had slid completely to the side as I stroked against her – exposing her naked vagina to me. That was our routine.

Another time I remember wearing low fabric cut-offs, which couldn’t quite contain my erect hard-on. The head of my penis was very visible to Terri when she looked down while I was on sliding on top of her, there was probably a half inch of it sticking out the top of my cut-offs. She was riveted – her eyes couldn’t leave it as she watched it slide against her panties, orgasming almost instantly when she saw it.

Another time I was in short cut-offs with no underwear and the base of my erect penis, balls, and surrounding pubic hair were clearly visible as we briefly wrestled. Her eyes were glued to them until I got on top of her. Once I was on top of her, she wrapped her legs around me like a vise and with a few thrusts quickly orgasmed.

I also remember a couple of times when Terri got on top of me. I remember her on top of me, looking down at me and smiling, as she raised and lowered her panty-covered crotch against the erection in my pants. It was usually me doing the thrusting between her legs until she lost control, so her riding on top of me was an unusual admission of what we were doing and her desire to make me orgasm.

She rocked against my hard-on, trying to get the right pressure, but she couldn’t really get the friction right for either of us, so we switched to the usual position, with me on top, her legs wrapped around mine to pull me into her, thrusting against each other until she orgasmed.
