Want It Bad

I been mostly straight forever with a couple of curiosity tries at m2m over the years. Have lately become almost obsessed with the thought.
What I imagine is hooking up with a mature chap maybe from mid fifties and over. Like to imagine him relaxing on the couch with no pants and get between his legs and suck those big hairy low hangers whilst he's stroking himself. Want to make him moan and tell me to keep sucking them balls. Then I'd push his. legs up and glide my tongue down his musky crack and tease his hole making him moan more and beg for it when I dig my tongue deep up his arse and suck that hole til he blows his load on my face.
Really want to suck a fat old dick with my own dripping all down my leg and maybe even cum together. Think about him humming on my dick too.
