I've always had a liking for both sexes and have had fun with both sexes, until I met and then married my wife Jessica.
Her father Frank is the antipathy of a masculine muscular dominant male. So after being married to his daughter for two years (Fourteen months back) Imagine my surprise to hear him ask me at a family party, if I still liked sex with men and if I did, and get this, would I consider fucking him.

Me, his son in law, the person who's married to his youngest daughter. I must tell you I got all defensive telling him that was all in the past, until he literally dragged me into the bathroom and kissed me hard full on the lips. I was still in shock when his tongue entered my mouth and his hand reached down to play with my growing cock, through my shorts.

Thinking any minute he's going to start telling me it was a test of my faithfulness to his daughter, I tried to back away. It only had Frank drop to his knees, open my shorts and pull out my now fully erect cock. Not saying a word, my father in law, who's six foot three and two hundred plus pounds, took my cock into his mouth. As he sucked on my dick oh so expertly, he undid his shorts and with my cock still being sucked, he took them and his boxers off.

My dick was throbbing by the time he stood up, leant over the tub and told me to feed him my cock. Not wanting to disapoint a man who could easily crush me. I gripped his ass cheeks and then in one long movement, I entered a mans asshole, who I never thought in a billion years I get to fuck.

It was obvious I wasn't the first to fuck Frank, but it was also obvious, no one had fucked him in some time as his ass was so tight wrapped around my seven and half inch dick. In a out of body experience almost, I fucked my father in law for over ten minutes. Each time someone wanted to use the bathroom, he'd bellow out he was using it. When they went away, he'd tell me to carry on fucking him. Telling Frank I wanted to cum after about ten minutes, he said "Good, so do I" As I was about to pull out Frank said "Don't you fucking dare boy, I want your seed in me". No sooner than I'd begun to come, Franks cock let go without him touching himself. He came all over the tub in front of him, as I came filling his asshole.

Once we'd gotten dressed, he told me he wanted more of the same sometime. Walking out of the bathroom with my cum still deep up his ass, Frank turned to me and said "Oh yeh boy, this never happened, you hear".

It still never happens fourteen months on. Each time he visits our home and his daughters not in, he asks, or tells me more to the point, to fuck him, or has me fuck his mouth. Only last week when my wife was at her gym class, Frank turned up and had me fuck him, which I did for over an hour. I came once up his asshole as he lay his back. Then after sucking on my flaccid cock for about twenty minutes, he had me fuck him in our shower. We'd not long gone downstairs and dressed before his daughter walked in all sweaty. The shower I'd only just fucked her father in, saw his daughter wash away her exercise class sweat.

When she wanted some fun late that night, I made out I was tired, which I was. And took my time giving her a long slow pussy licking. Franks asshole is devine don't get me wrong, but I'm going to have to slow him down. Either that or start using dildo's to satisfy a man who loves me fucking his ass.
