Upstairs Neighbour

I'd not even call it proper sex, as we usually only did one position.
He likes me to be dressed up as a college boy, but with my trousers and boxers around my ankles.
He wants me knelt up on the end of my bed, or on my sofa. And he wants me already lubed up.
He'll walk in, usually after a text to say "Fifteen minutes" and look at my arsehole as he lowers his shorts or jogging bottoms.
Within seconds I'll feel his large thick cock at my rear hole and then he'll thrust in.
He loves fucking me hard and fast and he's normally cumming within five to ten minutes, which gives him lots of time to spunk up me, wipe his cock clean with the wipes I provide, and then he'll leave me to walk upstairs to their flat before his wife returns from the shops.
He's been fucking me for over a year and most weeks it's about three or four times a week.
However his wife has just taken on a volunteer job in a charity shop, so he told me yesterday after he'd fucked me in two different positions, kissing me in the missionary position, a first for us, he'll be spending more time with me.
For a sixty four year old he has a high sex drive, a gorgeous big cock and simply loves fucking me.
