Dave’s Slutty Sister

I’d known Dave for three years. When I started comprehensive school he had become a good friend of mine, and I regularly went over to his house to hang out. We’d usually play video games, listen to music, kick a ball around – the things all regular teenagers do I suppose, and I was more than welcome at his house by his parents who must have taken a shine to me.

However, the best thing about spending time at Dave’s was getting to see his sister Becky. Becky was two years older than me and Dave, but she went to the same school. She had big blue eyes that were complimented by full black eyelashes and an energetic frame of mascara. Her hair, which was full and wavy extended to halfway down her back. It was originally brunette, but was dyed peroxide blonde in a way that highlighted her roots and was almost kind of tacky, yet it gave her the appearance of being a complete slut, which, as most of the school knew, she was. She would always stroll around the hallways confidently wearing the shortest skirts she could get away with, and at the same time showing off her ample cleavage. Some guys preferred pert innocent looking tits, but this wasn’t the case with Becky. She had these really round, full breasts that always drove me nuts even though most of the guys in school had probably shot their load all over them. In that aspect I always thought she was out of my league – she rarely talked to me apart from the odd “hey” when she wasn’t busy texting one of her boyfriends. She was usually dating older guys, and wasn’t interested in anybody who didn’t have a car and money – she was one of those girls.

One night I was at Dave’s however, and she seemed pretty hung-up over something. I told Dave I had to go for a piss, and as I was walking down the corridor to the bathroom, I heard her in her room on the phone to one of her girlfriends. She was saying that her boyfriend had just finished her and that now she had no one to fuck her. Obviously, being a young male adult on his way to the bathroom, my cock jumped in my pants and I stopped. As you could imagine, I felt very sorry for her, having no one to fuck and all… the poor girl! Peering through the brief gap in the doorway, I could see that she was only wearing a red bra and a matching thong that showed off her outstanding curvy figure. She was marching around her room frowning, and I could make out a tattoo on her lower back of a red rose, just above her round arse. Her thong was riding right between the two cheeks, and at that moment all I could picture was me fucking my friend’s sister as hard as possible. I practically ran to the bathroom to rub one off, in my friend’s house no less.

After that I was at Dave’s house every night of the week. Becky was always dressing in short skirts and tops that left nothing to the imagination. One Tuesday night, she was dressed in my favourite outfit. A pair of black knee high boots with killer heels, over a pair of fishnet stockings that you could just see the top of underneath a red and white plaid skirt. Over that she wore a tight low cut top and she had obviously gone to the trouble of propping up her cleavage, something I noticed she had been doing a lot lately, even at school. She looked as she probably intended to look: like one of the dirtiest, sluttiest nymphos in the neighbourhood. It was no coincidence that she only went out when her parents weren’t around. That was usually while I was there though, so I was only treated to the sight of her for 10 minutes a night at most. She dominated my sexual fantasies however – every night when I masturbated porn didn’t come into it. The thought of fucking her was enough to drive me wild. I kind of wanted her to notice me, maybe talk to me so I could put a voice to my fantasy. It came to the point where the fact that she was my best friend’s sister was irrelevant. All I wanted was to fuck that girl.

One night I mentioned to Dave that his sister seemed to be out every night. He laughed and then said that since her boyfriend had dumped her, she had been desperate for sex and couldn’t get any as every boy in her grade had fucked her already and wouldn’t touch her again. It explained why she was out every night dressed like a pornstar at any rate. In one of my lesser moments of trying to play it cool however, I nearly let slip by saying that I’d kill to fuck her, but managed to catch my tongue and just laughed. I mean, you can’t violate the code right? You don’t sleep with your best friend’s sister… do you? Dave knew his sister slept around, as did I, but the thought of such a nasty girl, such an easy girl lapping up my cock in my best friend’s house was too tempting for me. I wasn’t looking for anything emotional, anything meaningful… I just wanted to fuck the shit out of her. She fitted into my fantasy so well. And with this information… well I had to go to the bathroom, just for a few minutes…

Walking down the corridor, I habitually slowed down as I passed Becky’s door. Surprisingly however, I was sure I could hear soft noises coming from her room. Suddenly intrigued, I leaned towards her door, careful to see if there was anyone around. There wasn’t. And then I realised what was going on.

The door was only slightly ajar, but what I could see certainly matched the noises! There was a full length mirror on the wall, and in it I could make out Becky lying on her bed, underneath the sheets, but with her legs apart. The back of her head was pressing into her pillow, with her eyes shut and a look of grimace on her face, and her body was writhing emphatically under the sheets. It became pretty clear what was going on… Becky was fucking herself with her door unlocked and two teenage boys next door. I couldn’t believe it. My heart began racing… and my cock was on the same wavelength. Careful so that she wouldn’t see me, I stayed silently where I was for another 30 seconds before my little man was at full mast… I simply had to rub one off. No doubt about it.

At this point I even pondered catching her in the act, hoping it would lead to something, but I realised that was unlikely and for once chose not to think with my dick. Still, what would any teenage boy do? You’ve imagined fucking this girl for weeks, and here she is, making herself cum in front of you without her even knowing.
