So for a while I’ve been cutting my girlfriends and some other friends hair. Two weeks ago my girlfriends sister asked if I could cut her hair too.

For a bit of background I’ve found her very attractive since I first met her. She’s tall and skinny with very much model looks. Not much of a butt but her tits have always seemed so nice and enticing to me. I’ve been around their parents place quite a bit and seen her walk around in a T-shirt with no bra and seen her nipples poke through and definitely had a hard time to not stare. Once I also caught a glimpse of a nipple through the neck of her T-shirt when she bent over. I’ve always wanted to see more and visualised it in my head but hey, what can you do.

So when I was cutting her hair she took off her sweater and only wore a bra not to get hair on her clothes. As I’m finishing up the shoulder band accidentally slips down and her breast becomes fully exposed showing a beautiful pale tit, maybe a c-cup, perfectly firm with a pink nipple fully hard from the cold air since she didn’t wear her sweater. She quickly fixed it and blushed and I had to readjust my pants so she wouldn’t notice my erection.

It was only a brief moment but damn it’s stuck in my mind and I’ve masturbated so many times over the mental image. There’s something so exciting about how forbidden it is and how she has not control over me now having seen it and pleasuring myself over the image of her breasts.
