Although I've put myself down as straight, I've always had a curiosity about men and gay sex.
So having said that, when I walked into my father in laws house three days ago, and witnessed him fucking a guy younger than myself, I couldn't help but watch. They were both naked and seemingly not bothered about being caught, as the door wasn't locked. My mother in law was at my house with my wife about to have a baby shower, which probably explains why they thought it ok to be fucking one another. All the same, I just carried on watching as my father in law fucked the young man mercilessly. Only when I moved to get a better look did they notice me, and even then, they didn't stop. Instead my father in law asked me if I wanted to join in, saying "I've always wanted a piece of your arse".
I didn't join in, or indeed stay to watch him cum up the young guys hole.
However I did later have a wank, thinking of him fucking me instead of the young man. The same night he text me to ask me not to say anything, but also added "I wasn't joking about fucking you by the way". Yesterday he text again "Get back to me if your interested. Debs (His wife) is away this weekend, Love to fuck that rear hole of yours". I already knew my mother in law was going to be away, as my wife will be with her taking a spa weekend. I replied by telling him I wasn't sure. His answer was "You damn well know you want my cock up your arsehole boy... 8 o'clock Saturday night".
The only thing I could think of to text back was "Sure, you buy the condoms".
It's not a nailed on thing I'm going to go round, but the more I think about it, the more I want to suck on his large cock and for him to fuck me.
