My wife has a friend from her job mark. He is a large man I mean six foot eight 240 pounds muscular well cut abs large pectoral biceps and triceps. Being hiking buddies conversations come up he is bisexual. I was molested as a kid and since have Wonder what it would be like willingly to let a larger man fuck me. We were hiking one day and sat on a log well off trail well away from people. I looked over I'm 5 foot 9 average build. Looking as his hard body touched his dick over his shorts he smiled. It took me a minute but I learned to suck his cock it was fun a little lube and like a natural I took all ten inches of his cock in my ass it felt amazing. He dumped several loads in my ass his cum staying in my ass. When we got to my house we showered together I sucked his cock swallowed his cum. My girl got home we had a threesome she watched mark fuck me for a long while I fucked her. Now when me and mark hand out I let him use me as a fuck toy.
