Vacation Fun

by BB 2 years ago, my wife's brother invited me up to his vacation home in Tennessee for a weekend when our wives were at the spa. I was anxious to go because though I am married I have always been attracted to my brother in law Jeff. He is about 6'4" with huge, sexy pecs and dark nipples. One of my "goals" for the trip was to get my first ever glimpse of Jeff's cock. I had fantasized about what it looked like for a long time. I got my chance on the first night, when he was taking a piss. I went in, pretending that I had left something in there that I needed. I opened the door, and there was Jeff. I stared at his dick in shock. It was only 3 inches long or so, and thin too. Not what I had jerked off to in my head so many times! Well, he must have caught me staring because he looked at me and said "I think you need a chance to see me in action." I couldn't believe it! My dick was already hard and started leaking precum like a faucet inside my boxers. I dropped my pants and showed him my growing hard-on. Well, that was enough to get Jeff going. He started to get hard, and there was another shock! His raging hardon grew and grew--his cock gained 2 inches and was as wide as a Coke can! By then, clear precum was dripping down onto my thighs. My dick was drooling everywhere and throbbing like crazy. I needed to get off fast! "Come here" he said. He leaned me up against the bathroom wall. "let me show you what a real man feels like." He spit on his hand and put 1 finger inside my ass and swirled it around, then 2, 3, 4, 5 fingers. "You're ready" he told me. When he tried to shove his big, thick cock into my asshole I didn't think it would fit. "Wow" he said. "You are really tight!" I screamed form the pain. "Push back" he said, and suddenly the head popped in! I felt a huge burning sensation as his dick tore into my ass. But even though it hurt so bad, I touched my dick below me and knew taht I was harder than I had ever been. He reached around and started stroking me as he fucked my ass, and I lost all control. Huge spurts of cum were pouring out of my cock and onto the wall in front of me. I came so hard, some splashed back onto my chest! It was incredible! At the same time, he began to cum in my ass. When he had filled me up with jism, he pulled out. I felt empty without his thick cock in me. He turned me around and licked my own cum off the wall and off me. Then he left. We never mentioned that experience again, but it is one I will never forget!
