Friends Grandfather

My best friends grandfather has been fucking me over the last four months.
I'm secretly bisexual and have always enjoyed taking older mens cocks up my arsehole. It's something that began in my mid teens with a grocery store owner.
He was the first to feed me his cock and fuck me in a back room of his shop.

After him I began giving out vibes to men who I thought might want sex, and up until my friends grandfather began fucking me, over twenty different older men have enjoyed my mouth or backside.
My friends grandfather and I began fucking when I discovered his profile page on a hookup site. There was no face pic, but there were cock pics and I recognised a tattoo he has on his lower abdomen.
I'd seen it during a summer break years before when swimming at a local beauty spot.

I messaged him four months ago saying I'd love to suck his fat cock and met F that same evening.
He was surprised it was me when I entered his car at a lay by we'd agreed to meet at, but still let me suck him off.
Two days later in his flat, F fucked me three times over a two hour period. And I have to say he's one hell of a lover at sixty three years old.

In between Christmas and new year F shared me with a friend of his. It was a bit of a drunken fuck, but I still thoroughly enjoyed having both men cum over and in me. And F's friend has The biggest cock I've ever taken up my arse. He's not from our area and was only visiting, so it was probably a one off. Even so it was some experience having a nine and a half inch cock sliding up my rear.

F took video on his phone of his friend fucking me, and F and I have watched it a few times already on his tv, as he's fucked me.

Our sexual times together are just that, me and F fucking. He enjoys young men and I love older cock.
