My Sister Vickie – by MrTony

Her eyes were still fixed on mine. But as my thirteen-year-old sister bounced on my leg what I especially liked was that she was letting me watch her as I masturbated her. She gradually became more and more flushed and aroused with her rhythmic, well-timed bounces – each bounce now ending in a distinct rub against my thigh.

As she continued to ride on my thigh she grew more and more distracted and distant – I could see the lust consuming her. And I liked that I had my hands on her real, feminine hips – I could inhale her scent and watch her breasts bouncing just inches from me. And she was old enough to understand the concept of incestuous sex her brother – and she was choosing to masturbate with me. I think the family resemblance made me especially attractive to her.

Her pace increased – and I noticed her spreading her legs much wider. I used my hands on her hips to keep her balanced as her legs opened wide in the air while she rode me. This wasn’t a little-girl’s arousal. And she wasn’t just a little aroused – her orgasm was quickly approaching – and I could feel her wetness soaking my pants where her vagina was riding me.

No pretense of self-control, her cheeks flushed, she closed her eyes and tilted her head back, and breathed through her open mouth as the flush in her face became a bright red – sensually contrasting with her light freckles. Her pace quickened more – going too fast to keep a rhythm. Openly desperate to orgasm – it was an almost shocking lewdness in my thirteen-year-old sister. Her widely spread legs revealed her wanton desire to be fucked – and not just fucked by anyone – but fucked by me.

But now in a another change of our old ritual she put her feet on the floor, being tall enough to use her own legs to move her body back and forth on my thigh. She rode me while her fingers squeezed my shoulders in time with her ride to her approaching orgasm. The wet spot was huge under her – dripping down the sides of my thigh as her body instinctively lubricated for sexual intercourse. That was another difference from earlier times. She was older, and choosing to debase herself with her brother, and adult enough to gush between her legs with a thirteen-year-old’s desire for my sixteen year-old cock.

Both of us older, it was different but still familiar. I could tell when the first wave of her orgasm was about to arrive when she leaned her lower body forward, getting friction to her clitoris so that it could thrust against me as she orgasmed. Familiar too was her involuntary gasping, as she opened her eyes to look into mine as her orgasm arrived.

She leaned forward to hug me tightly with the first wave, throwing her head on my shoulder and looking into my eyes. I think I enjoyed this experience with her more than any other. It was wonderful to have Vickie – still a little girl – so willing to orgasm again in my arms. Then, taken completely by her orgasm, she was gasping, squeezing me tightly with all her strength, and making small sounds of pleasure as it arrived.

I held my hands lightly on her thrusting hips, and with each wave of her orgasm Vickie arched her body against mine. I could see the familiar euphoria in her eyes – holding my gaze through her entire orgasm. I’d never enjoyed seeing someone orgasm more.

It was just as I remembered, and, as always, I enjoyed watching Vickie orgasm. It was so familiar – but also different. She had spread her legs wide to get better contact and she had clearly signaled that she wanted me to do more to her – even to fuck her. And I liked knowing that she better understood what we were doing – I think our ages had increased her lust tenfold.

At sixteen and thirteen, we both knew there was the real possibility of doing more than masturbation. Perhaps she was wondering if we might start doing more now that we were older? And now the entire leg of my pants was soaked, and she continued to cling tightly to me. She was still breathing hard, and I could feel her breasts against my chest. When she opened her eyes, she looked at me with the understanding that we had just shared something wonderful. And I could see that she was very pleased with our intimacy, and eager for more.

I was pleased too. She had lots of boys chasing her – wanting to fuck her – but she had spread her legs for me to masturbate her.

But We Never Did More

I’m sure that with just a bit of planning I could have gotten my sister naked and fucked her. Considering how much she was already letting me do – and the undeniable intimacy of bringing her to orgasm week after week – I’m sure that she wanted desperately to be fucked by me. But she couldn’t admit to that if I asked. But she always let me to masturbate her, which was undeniably intimate, so I knew that she wanted me to get her undressed and take her. I just had to do it.

I’d noticed that she would lose control – and lose any sense of propriety as she got turned-on. And once aroused, she would let me position her body any way that I wanted – not caring if my hands were outside or under her dress. And sometimes, when she was desperate to orgasm, she would wildly reach out and put her hand on my penis, squeezing it in time to her own pelvic thrusts as her own orgasm arrived. She never did more than feel the outside of my pants, though, since she would always orgasm quickly once she felt the rock-hard erection she gave me. A few times she was trying to unzip my pants when she got distracted as her own orgasm arrived.

So I could have easily gotten her panties off when she had completely lost control. I would have to be direct – not giving her time to think of it as a question needing an answer. First I would lower my leg so that she would stand on the floor. I would give her a reason to undress, saying “These are in my way” as I pulled her panties down and adding “lift your leg” so I could get them off. I’m sure she would let me. Then, without panties, as the right moment arrived I would put my hand on her naked mound to amplify her orgasm – sliding my finger into her.

And since I would often adjust her on my knee before we played, I could start checking between her legs for good contact. And that inspection could include first feeling the outside of her vagina, and then progress to rubbing inside her lips. It probably would have been no more than one day before I was giving her orgasms with my hand – fucking her with my finger until she came. After that, she would know to take her panties off before we played “bucking horse”.

She had several times in the past wildly tried to loosen my pants, so all I had to do was make it easier for both of us. In the morning when I was in my robe I could ask her to play bucking horse. So I would already be naked so she could access my penis directly. Several times I had already slid her body up my knee to where she was against my penis – but now it would have a new dimension with her naked vagina and my naked penis sliding together.

At that point she would be completely compromised and aroused, and it would just be a matter of helping lift her up to mount my penis – the first real penis inside my thirteen-year-old sister. Knowing her desire for exactly that, I’m sure she would be trying to get penetrated as fast as possible and we would be fucking.

I would have loved to watch her expression when the head of my penis first entered her. And I would have loved watching her orgasming in response to my semen squirting inside her. I’m sure she would have wanted to get fucked every day – no more masturbation. I would have liked doing that for her.
