As I climbed the ladder I was excited. I could feel my heart pounding in my chest, in anticipation of what might happen. I knew that what I was about to do was wrong, but I couldn't stop myself from doing it, even if I wanted to. It had become an obsession.
When I stepped into the attic, I was careful not to make a sound, because if I was found out, then it would be the end of it. I then walked slowly towards the box that was covering the hole. Hopefully, when I moved it, a shaft of light would pierce the attic, telling me that the bedroom light was on. But disappointingly, when I lifted it up, there wasn't one. And even worse, when I put my ear to the hole, all I heard was snoring. I'd struck out. My Sister was asleep.
Purely by chance, I'd discovered the hole a month ago, when I was looking for something in the attic. I'd moved a couple of boxes, and there it was. And now that I'd noticed it, I did what most people would do. I put my eye to it. For a small hole, it gave quite a good view of the room below. Lucy's bedroom.
If she hadn't been in her room, there would have been nothing to see, and I would have then continued to look for the missing book. But she was, and she was starting to undress. In my defence, I did try to do the right thing, by walking away. However, after only a couple of steps, I stopped, and then I went back to the hole. It would be amusing to have a quick peek at my Sister.
When my eye was back to the hole, I could see that she was unbuttoning her top. I'd wait until it was off, and then I'd stop. There was no harm in seeing her in her bra. That would be no more revealing than seeing her in a bikini, and I'd seen that lots of times before. But when her blouse was off, she did something that I wasn't expecting her to do. She was pulling on her nipples. I'd started watching her out of curiosity, but now I was continuing because she was exciting me.
Then she suddenly stopped, but only so that she could take her bra off. My eyes were now glued to her tits as she was unhooking it. When it dropped onto the floor, I almost gasped. That would have been embarrassing. My Sister discovering that I was spying on her. And worse, she'd tell Mother.
I was now admiring her large breasts. They were always on display, but she had kept her prominent nipples hidden. And now I was seeing them for the first time. Just looking at them was making my mouth water. They were perfect, and I wanted to suck on them.
When she'd just had her bra on, she'd played with her nipples. Now that she was topless, she was massaging both her breasts with her hands. Then, after lying down on the bed, her touch became slower and gentler. She was now caressing them, like a lover would do. And I wished that I could be that lover. While she was doing it, she was occasionally moaning, especially when her fingers were on her nipples.
I'm John, and I'm twenty three, four years older than my Sister. I lost my virginity when I was nineteen. Since then, I've been with quite a few women, but I can't remember the last time that I was as excited as this. And I wasn't even taking part, all I was doing was watching.
Her hands were now rougher. Caressing had become groping. She was doing to them, what I wanted to do to them. That was frustrating, but there was a way that I could join in.
After unbuttoning my jeans, I pulled the zip down. I knew that it would have barely made a sound, but to my heightened senses it seemed loud. As soon as I got my jeans and boxers down to my ankles, my eye was back to the hole, and my hand was on my swollen cock. It's not a monster, six inches on a good day. And this was definitely a good day!
She now had only one hand on her breasts, the other was between her wide open legs. In her eagerness to get to her pussy, she hadn't wasted any time on taking her skirt or panties off. She'd just hitched her skirt up, and then she'd pulled her panties to one side. To me, that was more erotic than if she'd taken them off.
As she eagerly fingered herself, I was stroking my cock with equal ferocity. And when she speeded up, I did as well. I was matching her. I wanted us to reach it together. But that turned out to be wishful thinking, because without any warning, her body convulsed, and her beautiful face contorted into a grotesque mask. She was climaxing, but I still needed more time. I was now frantically trying to catch-up.
By the time I got there, she was coming down from her high. The first spurt was so intense, that it took all of my self-control to stay silent. I had to stifle a grunt. And the next one was just as powerful. When it was over, my hand was sticky, and I'd splattered the attic floor with my semen.
I continued watching, hoping that she would do something else that would excite me. But it soon became clear that one climax was all she needed. After quickly taking her skirt and panties off, and then getting into bed, she turned the light off.
And that was how it had started!
I wasn't proud about what I was doing, and it did make me feel guilty. But the excitement that I got from watching Lucy in her bedroom was compelling me to continue. So now, as often as I could, I would spy on her. Most of the time there was nothing to see, but occasionally, like the first time, I'd get lucky.
Today, we all had breakfast together. That was unusual. It's normally just Mother and me, but for some reason my Sister was up early, and she'd joined us. While she was eating, I took the opportunity to sneak a quick look at her breasts. They were impressive. Hopefully, I'd get to see more of them tonight, especially her large nipples, when I was in the attic. And if I was very lucky, I'd finally get to see her pussy. Up to now, when she'd been completely naked, she'd always been standing up, so from above, all I'd been able to see was her bush. Ideally, I wanted her lying naked on the bed, with her legs wide open.
"Can Ryan sleep tonight?"
Mother looked confused, and then she said, "I thought he was called Brad."
After laughing, my Sister said, "He's history, now it's Ryan."
"You know I don't like your boyfriends sleeping over. It's the same rule for John and his girlfriends."
"But he never has a girlfriend."
That was harsh. Yes, it had been six months since I'd had one, but I was successful with women. It was just that I was currently going through a lean period.
"Please can he?"
Mother was about to answer her, and I knew that it would be a no, but before she could, I jumped in.
"You should let him sleep here. Lucy is nineteen. She's an adult, and you should treat her like one."
That surprised both of them, because I was sticking up for my Sister. We get on OK, but like all siblings, there's a rivalry between us. I was doing it for my benefit, and not hers. If Mother was to allow it, then tonight when I was in the attic, I'd be able to see them together.
For a few seconds there was silence, while they processed what I'd said, and then Mother spoke.
"I'll think about it."
That evening, when I got back from work, Lucy greeted me with a big hug. It was so tight that her large breasts were squashed against my chest. I liked that, and my cock liked it even better. I was now struggling to keep it under control.
"Thanks, I owe you one. If there's anything you want me to do for you, then just let me know."
Good, so Mother had said yes. Ryan would be sleeping with Lucy tonight. And there was something that I wanted her to do for me. Tonight, while they were fucking, she could keep the light on!
Ryan came round at seven. He seemed a nice guy, and he was a cut above her usual boyfriends, because he actually had a brain. My Sister is a stunner, and if she wanted to be, she could be a model. However, she was also clever, and she was using her intelligence, rather than her looks, because she was studying physics at university. But for some reason, that I'd never been able to figure out, she preferred boyfriends that were always a bit dim. Good looking, yes, but not the sharpest knives in the drawer. Ryan was definitely the exception. Perhaps not as physically impressive as some of her other boyfriends, but certainly her equal in terms of intelligence, because he was also at university, studying mathematics.
At ten o'clock, they went to bed, and I did as well. As soon as I was in my room I locked the door, and then I quickly took my jeans and boxers off. As I was pulling the attic ladder down, there was a smile on my face. This was going to be good.
The attic was dark, but not pitch-black, so if I was cautious, I could safely make my way to the hole. As I walked towards it, I could hear them laughing. When I got to the box that was covering it, the anticipation was almost too much for me. But was I going to be disappointed? Then I almost laughed. My Sister was nineteen, and her new boyfriend was with her in her bedroom. It was a certainty that they would be having sex.
The box didn't contain anything of value, or anything that would break if it was dropped. But I moved it with the utmost caution, because if I was to drop it, the noise would alert them. They would then know that there was somebody in the attic.
Sometimes your hopes are dashed. You want something so much that it hurts, but it doesn't happen, and you are bitterly disappointed. But occasionally, like now, you get exactly what you want. They were kissing, and the light was on!
When he started groping her tits, my hand went to my cock. She let him have a quick feel, and then she moved away from him, so that she could take her T-shirt off. When it was off, she turned around so that he could unfasten her bra. He quickly did it, and when she turned to face him, she was topless.
He was now giving her tits the attention that they deserved. He was greedily sucking on one of them, and his fingers were on the other. And she was showing her appreciation of what he was doing, by moaning loudly. This was good, but it was going to get even better when her pussy joined in.
While I was watching them, I was slowly stroking my cock, but now I had to stop doing it. I was too excited. Coming now would spoil it. They were taking their time, making it last. I needed to do the same.
They were sitting on the bed, but when my Sister started to take Ryan's top off, they got off it, and then they quickly undressed each other. As soon as they were naked, her hand was on his cock, and his hand was between her legs. I wanted her back on the bed, with her legs wide open, so that I could see her pussy. They made me wait. It was agonizing for me, but when it happened, I got the perfect view.
I couldn't believe it. If I'd choreographed it, I couldn't have done a better job. She was on her back, and her legs weren't just wide open, she had her knees high up. Ryan was fingering her, but because he was sitting to the side of her, he wasn't blocking my view.
As I admired her pussy, my hand went back onto my cock. She had large lips. There was a lot of meat between her legs. Her clit was hidden under all the folds, for me to see it, he would have to part her labia. Hopefully, he was going to do that, but for now, he was content to just move his two fingers in and out of her. And from the noises that she was making, she was happy with what he was doing to her.
But what about him? Did Ryan have a monster cock, one that would stretch my Sister's pussy to its limit? Would it be so big that it would make me envious? No, and when I saw it I felt good, because mine was at least half an inch bigger than his.
