I'm in my bedroom in my parents house watching my 50 yr old next door neighbour hanging out her washing in the shared back yard below. She is sexy curvy big titted mature who makes my cock hard. She is hanging out her sexy knickers and bras as usual, wearing a tight black skirt and a very low cut top showing a lot of tit. I get my cock out and start wanking watching as she bends over her skirt clinging to her massive arse, she has been my wanking fantasy for months. I get harder watching her stretch up to hang her knickers on the line, her skirt riding up to show a bit of stocking top, and her tits pushing out and against her top nearly falling out of her bra. She bends forward to get the last bra out of her basket showing me a great view of her massive tits, this sends me into a wanking frenzy and just as I am about to spunk she looks up and sees me cock in hand wanking, she watches as I spunk off shooting my spunk all over the window, then she smiles, gives me a little wave and goes back into the house. That night I am hard again thinking about her, her clothes are still on the line and I am filled with a lust to wank into her knickers. I strip naked go out into the back yard and take a pair of her black lacy pants off the line and wrap them round my cock. As I wank I look up at her back bedroom window, she is stood there watching me, she is topless and as I wank off she leans forward and squashes her huge tits against the window while rubbing her cunt. I shoot my spunk into her pants immediately cumming hard, it was fantastic. I hung the knickers back on the line and went back inside.
