Henry his Sister and Mary

It took me a while to understand what was happening, and that wasn’t surprising, because it wasn’t something you would expect your Sister to do. And also, initially she was being subtle, so it was easy to misinterpret what she was doing. Once or twice might be thought of as accidental, but when it became more than that, I realized that it was deliberate.

She was asking me to take part in a game, a dangerous one. Something that could have serious consequences. I was nineteen years old, so I was always eager for anything that was sexual. So even though I knew that it was a bad idea, one that I might regret, I was going to do it!

It started a week ago, and until now, I hadn’t given it much thought. We were in her room, with Mary, our friend. She was sitting at the desk, updating a Word document. It was a college project for the three of us. Mary was doing the typing, and we were standing behind her, supposedly, telling her what should go into the document. However, she was doing OK without our help.

When my Sister moved closer to me, so close that our thighs were now touching, and with quite a lot of pressure, I assumed it was so that she could get a better view of what Mary was typing. I tolerated it for a while, and then I stepped away from her. We were still near to each other but our bodies weren’t touching. But within seconds, she was again too near to me. This time her hand was brushing against mine, as if she was caressing it. Not just once, three times. Then she suddenly stopped doing it. I thought her behaviour odd, but it wasn’t something I was going to spend a lot of time thinking about.

The second time, a few days later, was different, more daring from her, but naively, its true meaning still passed me by.

As before, Mary was at the desk. Our project had to be handed in tomorrow and we were putting the finishing touches to it. We’d put a lot of effort into it so we were hopeful of getting a good grade. This time my Sister wasn’t next to me, she was behind me, looking over my shoulder.

At first, I thought it was her arm on my back, but then I realized that it was her breast. It made me smile. When you have tits the size of hers, sometimes they are going to bump into things. However, she must have noticed, so why wasn’t she stepping back? And now it wasn’t just touching me, it was moving about. Was she leaning against me? Then it was over. It hadn’t lasted long. There was no reason for her doing it, so I dismissed it as accidental.

The next time was when I saw the light. It was a sudden epiphany. Helen, my twin Sister, was doing it deliberately. And alarmingly, it was giving her sexual gratification!

Again, it was when Mary was with us, but this time we were in the living room watching television together. Our parents were out so we had the house to ourselves. I was sitting on the sofa with my Sister, and Mary was on the armchair that was opposite us. We’d sat like that in this room on numerous occasions, but tonight, something happened that was a first. She suddenly stretched her leg out so that she could put it onto my legs. I looked at her, trying to understand why she’d done it, but her face was impassive, telling me nothing. Then the film became interesting, so all my attention was on it.

When she slowly moved her leg, it was irritating, but I ignored it. Then, when it was on my lap, pushing down on my crotch, it was something that I couldn’t ignore. I quickly glanced at Mary, she was engrossed in the film so she wasn’t aware of what Helen was doing. But I definitely was, because of where her leg was, and the pressure it was exerting on my cock.

Then the inevitable happened, my manhood started to grow!

When I put my hand on her leg it should have been easy for me to push it off my lap, but it wasn’t. I was a lot stronger than her, but my attempt to move it failed because she was determined to keep it there. The second time worked, but only because she let me do it.

When I turned to look at her, it all became clear to me. As she stared at the impressive bulge in my trousers, there was a look of triumph on her face because she’d got what she’d wanted. She had aroused me.

There was another thirty minutes left of the film, and during that time my eyes were on the television, but my mind was elsewhere. I was thinking about my Sister and what she’d just done now, and earlier in the week.

By the time the film had ended I’d made a decision. I was happy to play her game, in fact, I was prepared to take it as far as she wanted to, perhaps even beyond that. Yes, she was my Sister, so she should be off limits. However, when a woman who is as hot as she is, offers herself to you, it’s difficult to refuse even when she’s your sibling.

I didn’t waste any time. In the morning, while we were having breakfast together, I made my move. At the first opportunity I stood close to her. I was smiling as I waited for her to respond. But the reaction I got wasn’t what I’d expected. When my hand casually brushed against her large breast, she froze, and the expression on her face told me everything. She was horrified. Then she quickly moved away from me. I mumbled sorry, for ‘accidentally’ touching her, and that was the end of it.

For the rest of the day I kept mulling it over. Why had she reacted in that way? I’d been convinced that she would have been responsive, as eager as I was for us to be intimate. Eventually, after being unable to come up with an answer, I put it to bed. It was going to have to stay as one of life’s great mysteries.

However, the next day I learnt some important information about the game that my Sister was playing. It had rules, and there was a key one!

We were alone in her bedroom, enjoying each other’s company. Being twins, and on the same course at our local college, meant that we had a lot in common. Unlike a lot of siblings, we didn’t argue, we had a good relationship.

“Why don’t you like Mary?”

I did. I’d known her a long time. She wasn’t just her friend she was mine as well.

“I do,” and then, after giving her a quizzical look, I added, “And you know that.”

“What I mean is, why haven’t you asked her out?”

“I have, lots of times.”

That surprised her, but then, when she saw me smirking, she gave a deep sigh.

“Don’t be an idiot, you know what I mean.”

I did know, I was just messing with her. I was always asking Mary to come over, or to go out with me, but just as a friend. I was going to take my time before answering, to make it look as if I was thinking about it for the first time. However, it was something that I’d thought about a lot.

Mary was a woman that you should have as your girlfriend. She was kind and considerate, always cheerful. And she was clever, a lot cleverer than Helen or me. Any man would be lucky to have her, but for me there was a problem, she didn’t turn me on. She was pretty rather than beautiful, and her body had curves, but not enough for me. Her breasts were more than a handful, but disappointingly, they weren’t big enough to excite me. My Sister was now getting impatient. It was time to give her my answer.

“I like her, but I’m not attracted to her.”

The look that I got from her told me that she thought that I was a fool. I might be, but there was nothing I could do about it. Mary didn’t get my juices flowing, and that was the end of it.

However, if she had the looks and the body that my Sister had, then I’d be all over her like a rash!

Thirty minutes later, Mary was with us. We weren’t expecting her, she’d just come to see us on a whim. To me, it felt as if she’d come because we’d been talking about her. Of course, I knew that was silly, it was just a coincidence.

“Hands up if you want to work on our next project?”

Only Mary raised her hand, and it had been her who had asked the question. I looked at my Sister, she nodded, and then her hand was also up. Like me, she’d been reluctant, but she knew that it was the sensible thing to do because we only had a week to complete it and there was still a lot to do. After giving a deep sigh, that was so loud that it made the others laugh, my hand shot up, as high as it could go, and they laughed again.

I was chosen to do the typing, but after only fifteen minutes, and a lot of complaints from my Sister because I was too slow, Mary replaced me. That hurt my pride, but it was the smart thing to do because we were now making good progress.

At first I didn’t notice because I was too engrossed in what we were doing. When I did, I was confused. She was behind me, and she’d moved closer so that her large breasts were pressing against me. What was she playing at? The last time that she’d done that I’d been convinced that it was her way of telling me that she wanted us to be intimate. That she wanted me to touch her in places that a Brother shouldn’t. However, when I’d done that in the kitchen, by briefly moving my hand over her breast, she’d recoiled in horror. Then she spoke.

She’d said it softly, with her mouth close to my ear so that only I could hear it. I did, every word, and now my mind was in turmoil. She’d asked me to put my hand between her legs!

Was it a trap, her idea of a joke? I’d do it, and then she’d embarrass me by loudly complaining. Mary wouldn’t find it funny, she might even be angry with me because of my disgusting behaviour. But my Sister wasn’t like that. There must be a logical explanation for her behaviour, but I wasn’t smart enough to figure it out. Then I almost laughed when I realized that Mary, with her superior intelligence, would probably be able to.

Of course, I wanted to do what she’d asked, even though we weren’t alone, but should I? Common sense said no, but my expanding cock said yes. It was a difficult decision. Why is life so complicated?

Then, to encourage me, she whispered, “I want you to touch me.”

That wasn’t a help, because I already knew that. However, what she said next was. I could now decide.

“You can do it when Mary is with us,” and then, after a brief pause, she added, “Just thinking about it is making me wet.”
