My Sister Vickie – by MrTony

True sex story: My Sister Vickie. Author: MrTony. How I masturbated my sister Vickie as we played games. I was a naive, quiet 12 year old kid. I was in my room masturbating, and I wondered what it would be like to have real sex. I knew that a girl would probably close her eyes, breath heavily, maybe even gasp, and then arch her back as she came. At that moment, I realized that I’d seen that exact thing before – when playing with my sister! This story is including of True Story, Incest, Masturbation, Teen theme.

True sex story: My Sister Vickie

Author: MrTony.

Growing up, I often played games with my sister Vickie.

Vickie’s favorite game was “bucking horse”. She would balance on my knee as I tried to bounce her off. Lately, I had noticed that she would bounce up and down for a while before “cheating” by locking her legs tightly around my leg. And sometimes when I had stopped playing, she would continue bouncing on my leg.

She would always end up burying her head into my shoulder as she squeezed me tightly, often gasping as she squeezed me most tightly. I had occasionally noticed a faraway look in her eyes just before she would place her head on my shoulder. I hadn’t understood why she would turn her face away from me while squeezing me so incredibly tightly.

Now I understood. The faraway look in her eyes – her gasps. I’d finally realized that my sister had been masturbating with me. And I hadn’t expected that. I never thought that she would orgasm with me, her own brother. So I finally understood why she liked this game, and why she always hid her face and closed her eyes. She was hiding her face while she orgasmed.

As a girl she was supposed to be “proper” and “modest”, so even though she seemed to want me to know the effect I was having on her, I was her brother, and she certainly couldn’t just ask me to feel-her-up. But she could show me that she was willing to let me fuck her.

My sister had probably orgasmed 20 times with me before I realized this. I guess I wasn’t the brightest kid, since she apparently wanted me to notice. What a fool I was. So I immediately got dressed and went downstairs to find my sister. I wanted to watch her orgasm.

Playing with Vickie

Well, we hadn’t played that game lately. My sister had stopped asking me to play, probably because I wasn’t responding to her sexually. She must have realized how dim-witted I was. When I went downstairs to find my sister I was hoping that I wouldn’t have to beg her to play.

Luckily, Vickie was home, and I asked her if she wanted to play “bucking horse”. Without an instant of hesitation, she agreed. So Vickie, wearing a skirt, got on my leg, and I started trying to buck her off. She played for a while, but she seemed to grow more and more distracted. Seeing the growing flush on her face, and her more intense effort to angle her body so that the front of her panty-covered crotch was in contact with my leg, I suspected that she was aroused – and trying to hide it.

But I felt her growing wetness on my leg. So to test my theory, to see if my sister was really getting sexually aroused, I stopped bucking my leg. Without losing her rhythm, she continued to move on my leg by herself – forcefully wrapping her legs tightly around my thigh – clearly not planning to stop. She had briefly glanced at me with a questioning look – an “are you noticing what we’re doing?” look – before her rhythmic rubbing again fully distracted her. I had discovered just how aroused she was. She was clearly too excited to stop.

Too Turned-on To Stop

But that was fine with me. I liked knowing that my sister was so aroused that she was about to have an orgasm with me, her own brother. Now that I recognized her lewd desire to be masturbated – I wanted to help. So with her crotch now pumping my leg in earnest, and me carefully returning each small thrust, her rubbing quickly increased until she was barely able to hold a rhythm, and her riding was soon accompanied by audible breathing.

Seeing her loss of control, I put one hand in the small of her back, sliding her small body forward into me with her thrust. The friction combined with my overt help brought on her orgasm, and as her orgasm arrived she leaned forward to hug me tightly, to bury her head in my shoulder. But I wanted to watch a girl orgasm – so I took hold of her cheek and I turned her head to face me.

I thought my brazen desire to have her face me as she orgasmed might get a negative reaction – but the only reaction I got was my sister eagerly looking into my eyes as she rocked her pelvis into me with even more enthusiasm. If anything, she was more aroused knowing that I wanted to watch her orgasm.

I kept my eyes on hers while her orgasm took hold of her. It had her gasping for air, her mouth partly open – angling her clitoris to keep pressing against me. As she orgasmed she arched her body against mine perhaps three times, pushing her clitoris against me forcefully with each of her thrusts. Her body was so small, and with my hand on her back, she was able to slide herself up against me with her thrusts.

I watched as her eyes revealed the intense joy I was giving her, as I masturbated my own sister – and as I enjoyed the soft sounds of my sister’s pleasure. Her eyes stayed locked on mine as her orgasm gradually subsided, and a contented glow slowly took over her very flushed face. She seemed to slowly return from somewhere distant, and seemed reluctant to let me go – her arms staying wrapped tightly around me – resting contentedly in my arms.

We Would Do It Again…and Again

I had just watched my sister orgasm for the first time. She had made a big wet spot along my thigh, and the whole room smelled of sex. I could tell that she loved having me watch her. And she’d seen that I’d very willingly masturbated her. I didn’t know it yet, but in the future, she would always grip me with all her strength as she orgasmed, facing me, gazing into my eyes as her lust, desire, and desperation gradually became contentment – her eyes always stayed locked on mine – knowing how much I enjoyed watching her orgasm.

Perhaps I should have been embarrassed about masturbating my own sister. But, instead of being embarrassed, I liked knowing that my sister was always wet and ready for me to masturbate her, and I liked knowing that she wanted her brother in a way that no sister should want a brother.

We kept Playing

This more mature version of our game became a ritual for perhaps a year. We probably played a couple of times a week, or whenever we had the opportunity, never really talking about what we were really doing. But our “bucking” time became Vickie quickly mounting my leg – gazing into my eyes as I watched her grow flushed, gasp as her orgasm approached, and then hold me tight as she lost all control and orgasmed. Of course, there was the occasional exception when she had multiple orgasms – surprising me by coming two or even three times as she clung tightly to me.

The Last Time We Played

As time went by, I got busy with other activities, and we played less and less. I think the last time we played was when I was 16 and Vickie was 13. We were both maturing fast in those years. But one day I was thinking about sex and I remembered that it wasn’t so long ago that Vickie would masturbate with me. We were both older, but I wondered how she would react now if I made the outlandish suggestion that we play our old, childish, masturbation game – did she still remember what we did?

Had I embellished her erotic enthusiasm in my mind? But I figured that this would be my last chance to find out her reaction. Weren’t we too old to pretend that it wasn’t really just me masturbating her? So I found Vickie and asked her if she wanted to play – thinking she would say no, and thinking that we might both be embarrassed by my suggestion.

I was surprised when, after just a bit of thought, she very calmly – and very, very slowly – said “yeeees”. She had never had to stop and think about it before, so she obviously understood the significance of my suggestion – and she was weighing the idea of her brother masturbating her to an incestuous orgasm. We had reached an age where we knew what we were agreeing to – we were agreeing to have an intimate sexual experience with each other – exposing our lusts and desires.

One Last Game With Vickie

Vickie was thirteen now, and certainly knew a brother isn’t supposed to masturbate his sister. But she knew exactly what we were doing. Maybe she didn’t want to admit to herself what I was about to do to her? Or maybe Vickie had thought that she would be able to hide her lust and just play “bucking horse” with me? I was about to find out.

Vickie had gotten much too big to sit on my leg and be bounced off – at thirteen she was becoming a young woman. She wasn’t really a child – she had a young woman’s breasts and real curves. She’d stopped playing with dolls, and now experimented with make-up and different skirt lengths as the boys vied for her attention.

Almost as tall as me, I had no ability to bounce her on my leg. In spite of all that, she didn’t suggest that we not play. Instead, feigning indifference about being too big to bounce, she immodestly lifted her skirt high, exposing her white panties to me as she sat on my thigh. She then made a long show of daintily tucking down her skirt around my leg where her moist, warm crotch now rested. Then she gamely put her hands on top of my shoulders. I hadn’t moved, since she was now much taller than me when she sat on my thigh.

I said that since I couldn’t bounce her perhaps we couldn’t play. In response, she started to “bounce” her body up and down on my leg so I could try to “bounce” her off. Being so big, her body was unstable on my leg. But now she had real, feminine, hips – so I placed my hands on her hips to help her stay balanced as she bounced. I didn’t know if she could tell, but I was just as eager as she was. I wanted to feel this young girl orgasm.

We started, but before long, her bouncing slowed to a regular pace. When my leg moved, she would try to hold it with her legs – trying to control the pace and pressure. Her eyes held mine, and I could sense my sister’s questions to me – “Can you tell what I’m trying to do with the pace? Do you know what it’s going to do to me? Can you tell what you can make happen?” I think she wanted to see if this game was as much fun as she remembered.
