Spying On My Sister

by RandyStroker

"How come Liz can have friends sleepover and I can't?"

My mother looked at me briefly and then returned to her book.

"Because boys don't have sleepovers. Girls do."

"But, Mom, that's not fair!"

I felt tears of resentment welling up in my eyes, but I fought them back. I didn't want my mom to see me crying.

"Don't be silly, Randy. Girls have sleepovers, boys don't. End of story."

I went out into the garden and kicked a ball around for a while. I hated how girls seemed to get all the fun. And my sister, Liz, used to love rubbing my nose in it.

"I'm having my friends over for two nights, but you're not invited. So keep out of our way, dog breath!"

"Fuck you!"

"Oh! You said the F word. Just wait till I tell mom!"

"Fuck you! Fuck you! Fuck you! Tell mom and see if I care!"

"I guess you'd like to fuck me, wouldn't you, worthless piece of horse turd?! No way."

At thirteen, I had only a vague idea about fucking, but the way my pals described it, it sounded like it could be fun. But I wouldn't want to fuck my sister, Liz. I hated her too much for that. Mind you, I couldn't take my eyes off her tits, which had kind of exploded in the last year. But I hated her because, although she was only two years older than me, she had always bossed me around, and put me down, and tried every trick in the book to humiliate me.

"What are little girls made of? Sugar and spice and all things nice!" she would chant at me, knowing how I hated what came next: "What are little boys made of? Scabs and snails and puppy dog's tails!" And she would run off laughing, knowing she had humiliated me yet again.

My revenge really came when I learned to masturbate. The first time I shot my load, I was scared to death. I couldn't believe anything could feel so GOOD. After that, I just jerked off every chance I got, and my revenge was to shoot my semen into my sister's panties or bra that I would take from the linen basket and then put back before anyone caught me. And to be honest, I used to masturbate sometimes thinking about my sister Liz's breasts and imagining what it would be like to touch them.

I could also get off thinking about some of her friends, like Trudi, a blonde German girl who was staying with the people next door. Trudi was what you might call hard-faced, and never smiled at me, in fact she just ignored me, like I wasn't there. This, of course, made me masturbate all the more vigorously, thinking how I would love to shoot my load all over her snooty face. And the Bradley twins, Charlotte and Caroline, as like as two peas in a pod, long flowing dark hair, and a habit of wearing really short skirts which gave glimpses of their panties when they ran. I pumped out gallons of hot cum dreaming about those two.

But my interest in Liz and her friends went beyond lying in bed jacking off. I had found a way to spying on them! I could get into the roof space of our house through a skylight window that was never used, and had managed to create a spyhole just by the light fitting in the ceiling of my sister's bedroom. I had taken up some old pillows and cushions so I could lay myself full length on my stomach, cock in hand, and look down through my spyhole to see what my sister was doing. Not a lot usually, but I sometimes got a glimpse of her in her bra and panties, sometimes taking her clothes off, and that was enough to keep my fist pumping.

So, when I knew about the sleepover, I was trembling with excitement at the prospect of seeing not just Liz, but also that sullen German bitch, Trudi, and the sexy twins, Charlotte and Caroline. Four fuckable girls all in one room, and a bedroom at that! This was going to be the jack off session to end all jack off sessions! My only frustration was that my spyhole only gave me a view of about a half of the room. I didn't dare make the hole any bigger in case my bitch sister noticed it. Never mind, half a loaf is better than none, and what I couldn't see, my imagination could supply!

Although at that age - I am talking quite a long time ago - I could get it up and shoot my load maybe 3-4 times a day, I deliberately didn't wank for two days before the sleepover. I wanted to have a fucking tsunami of good honest boy-seed to shoot for these four bitches. Maybe I would never be allowed to join in their games, but I could, in my mind, drown them in my cum. Forget that shit about "scabs and snails", I could do something no girl could do: I could jack off and produce huge spurts of yummy cum, splashing it everywhere like I was trying to spray the whole fucking world with my jizz. So, fuck you, Liz and Trudi and Charlotte and Caroline, just TAKE THIS! I tell you, guys, I was as hard as a fucking rock for those long long hours before I was able to take my place on my cushions in the roof space, saving myself for the big eruptions. It was late evening, my mom was watching TV, the four girls had gone up to Liz's room and I could hear the usual giggling and whispering that seems to be the only way girls can communicate with each other. I peeped through my loving spyhole to see what the bitches were up to. All I needed was a glimpse of tit or thigh or butt and I would be able to start stroking while I imaginied myself really fucking or better yet raping them.

I couldn't see the twins, but Liz and the German bitch Trudi were in full view below me. Liz was seated at her dressing table, and Trudi was standing behind her, brush in hand. I watched how Trudi brushed my sister's hair really like lovingly. And then, fucking ding dong!!! Trudi put the brush down and slid her hands down Liz's front and over Liz's breasts, something I had dreamed of doing a zillion times. Liz leaned back and uttered a little moan as Trudi proceeded to caress Liz's breasts through the material of her blouse. Then, Trudi slid her hands under the blouse and cupped my sister's boobs in her hands and continued caressing them the way a man would do it. This was unbe-fucking-lievable! I wrapped my fist round my cock and started to stroke, but slowly, this was fucking AWSOME and I wanted to make it last. I watched as Liz turned her head towards Trudi, looked up at her and smiled. Trudi responded by leaning down and planting her mouth full on Liz's mouth, and they stayed like that for ages, kissing and tonguing, you know, real kissing like men and women do. I felt huge spasms in my cock. This was the greatest fucking turn-on that I had ever experienced! I couldn't help myself. The sight of my sister kissing another girl that way was overwhelming. In a few strokes, I felt my ballsac tightening as my balls aligned to send surge after surge of hot spunk erupting from my cock. I humped the pillow as I rode my orgasm, all the while keeping my eyes glued to the scene below. Fuck! I had intended to make it last, but I couldn't control myself. As my orgasm subsided, I began to wonder what the fuck was going on with my sister. I knew, at least I assumed, that she hated boys, well, she sure hated me, and I never saw her flirting with boys, except you know being snooty and ignoring them and stuff. Maybe she and the German girl were just practising, you know, pretending to be a boy and a girl so they could try out stuff ready for the real thing.

But of course, it soon became clear to me that these games that Liz and Trudi were playing were "the real thing" for them. It was clinched for me when the twin girls moved into shot and joined in the sex play. Liz put on some music and then Liz took one twin and Trudi the other - don't ask me which twin was which - and when they were paired off, they started dancing, but dancing like I never saw girls do before. It was slow type music, you know, that smoochy stuff you see in movies when the woman kind of clings to the guy like they wanted to fuck standing up. But in this case, I was watching four GIRLS doing exactly that smoochy stuff. Lots of kissing and fondling and hands sliding down over butts and pulling each other tight together, and I could just imagine how that must have felt, specially when the got their breasts together, or when they started like grinding their crotches against each other. In no time, I was hard again and all set for another jack off session, but this time a long slow lingering one, edging towards climax and drinking in the amazing scene below me.

Some days later, I got talking to one of my pals and I thought I could trust him, so I told him about the sleepover and what I had seen - in fact, I had to leave after my second cum or my mom would have wondered where the fuck I was - and he explained to me about lesbianism, which, as I am sure you know, is when women have sex with each other instead of with men. I went round to his place and he showed me some stuff on the web that would make your fucking toes curl. I had NO IDEA that girls did that stuff together! And to think that my own bitch sister Liz and her grim German friend Trudi, and the two sweet Bradley twins were into that stuff. Fucking ding dong again. I could believe all that pussylicking and fingfucking, just, but the stuff with the dildoes and the strapons, that was weird man, that was like off the planet. Surely they weren't that wild, that was just porno stuff?

How wrong can you be?
