For as long as I can remember I have been attracted to men aswell as women, but have only ever dated and fucked women. By chance I started dating a girl who's father was a friend and colleague of my father. We didn't really hit it off because she couldn't fully take all of my cock and it frustrated me. I called by their house to break it off, not wanting to dump her by text. She wasn't there but her father, Ken was. He let me in and we got chatting about why I was there. In a very weird conversation I sort of told him why, without going into too much detail. Ken answered by letting me know gay men took cock better. I don't know if Ken suspected I sometimes fancied other men, but he'd hit the spot, so to speak when he said what he said. I swear it wasn't planned and I also hadn't got a clue Ken was bisexual. So when he offered me his ass to fuck I was shocked, but I was also very fucking horny. Thirty minutes after entering my ex girlfriends house, I was entering her father's ass and I was fucking loving it. He'd sucked my dick to it's full eight and half inches and he'd sucked it deep down his throat too. It wasn't the most romantic fuck I've ever had, but who cared. It was on their kitchen floor as he knelt down and offered me his ass to fuck. Without a condom on, I eased my dick up his tight butt and began to fuck him as hard as he could take it. Within a couple of minutes I was balls deep up his hole, my balls slapping against his bare butt cheeks. He took every inch of my cock and he was loving it just as much as I was, if not more so, as he backed onto my dick. He asked me to masturbate him as I fucked him, so I reached round and started stroking his cock just like I like doing it to myself. Ken came first all over the kitchen floor and my hand. I came not long afterwards, but I came up his ass without pulling out. When I withdrew my dick, he began pushing and soon my cum was dribbling out of his asshole. He wasn't finished, Ken turned around and took my cock back into his mouth, licking and sucking my dick clean. I'm still dating his daughter, but I fuck Ken way more than I do her and it suits me and him fine. Soon I'm going to come out of the closet and declare myself bisexual. It's not as though I don't like women, I do. It's just that I now know I also love fucking a guys ass.
