My ex-wife and I had our 1st 3-sum way back in 1993. It was her brother in-law and she had always wanted to have sex with him, and they often flirted. It started when she went out to a tavern alone and met him there, and I was working until midnight. I stopped by the tavern after work and met her and she asked me if she could have a 3-sum with me and her brother in-law. Appartantly his then wife had gone away for the weekend. He was 5ft 6 inches tall and they have been flirting and making out for a while before I came along. I agreed and in short notice we were at our place and all naked as she sucked his cock. I am 6ft 4 inches tall and have a 8" long dick, but his dick was almost 10" long, but not as thick as mine. We both put her thru her paces for abut 4 hours and I took him to his place and went back home and fucked me ex again, before falling asleep. I found out later, she was well known for screwing around with loads of people, both men and women. They never repeated that night, as he wife always stuck around.
