Erogenous Zones

Christmas is, as my sister often tells me, "A cunt of a time". Yes, even she descends to foul language sometimes. Personally, I think our schooling affected her way more than me. I'm not confrontational or a rebel, but she is positively timid. She stuck to each rule as if it was the living word of God. She even measured the hemline of her skirt! I was never that bad.  But neither of us enjoy Christmas. This is mainly because our parents tend to leave us to it. Oh, don't get me wrong, they're kind and caring, but utterly self-obsessed with holidays. We have been making  our own arrangements since Allison was 17, and deemed old enough to look after me!  But to hear the "C" word...from Ally was, unusual. I didn't even think she knew it! So, I responded in kind. "Yeah, it's totally fucked up....a real kick in the cunt." She actually flushed up! Her face and neck turned bright pink right in front of me.    We were sharing a bottle of wine and just slobbing out. There was some pathetic late night show on the TV which neither of us were really paying attention to until the language on it got dirty. With each dirty word, I saw Ally squirm. Finally, I suggested we watch something 'more from up'. I've known the PIN code to the porn channels for ages, and soon found something interesting. It was just a couple fucking, but hey.....whatever works, right? 

Now, I finished my period yesterday and as usual, was super horny right through it and it usually carries on like that for a day or two. As I watched the couple fuck I just imagined it was me. Then something clicked in my mind, being filmed, a camera! My mind instantly left the TV and began to think up ways of videoing myself. I was planning it all out in my head and was totally lost in myself when I heard "Huhhh huuuuhhhh". Ally was sitting on her own heel and rocking her hips. I knew in a second she had cum! Ally! My sister! Oh, my fucking God!    Her eyes remained rooted to the TV. As she was sitting on the floor with her back to the couch, she couldn't really see me as I was sitting on it. So, I figured I'd go for it. I just slipped my hand into my underwear and found my magic button. Ally was still rocking slightly which I figured meant she was still coming down, or on the way to another one. Every fibre in my being wanted me to ask her to watch me, but I didn't want to risk freaking her out. 

To say I was wet doesn't cover it! I spread my knees wide and fingered my hole. (I can do that now...I'll tell you why/how another time). I let out a couple of moans so Ally would know what I was doing. She just began to rock more! I watched her intently, even though she thought I was watching the couple on the TV who had now changed to doggie style. 

I timed my orgasm to perfection. I could tell the moment she came, and I came with her. 

It was really string too, but I bit back on the noise. 

I realised that my sister IS a sexual being! How she copes with no boyfriend (or girlfriend) amazes me....I really didn't think sex interested her much, but it seems I was wrong.    Did we do anything together? No! You MUST be joking! Ah, but did I rub a couple off in bed later imagining that we did? Ooh yes!
