Howdy! All names and places are fictional

For story purposes my name is Mac and I want to tell a story about a cuckold from the bull’s side of things. I first met my future babe in blue jeans at a university in Montana. Ruth. I was a geneticist and Ruth was a fun and very pretty girl who had just gotten a job at the university. She was married but it soon became known that she liked to play on the side. I liked to flirt with her and one thing led to another. One night at a friend party Ruth and were I hot-tubing with the others including her husband. He was there before the party started and it turned out was nude in the tub. He was starting to overheat and nobody would let him leave and finally he just got up and laughing walked to the back bed rooms to dress. As he stood up his hard cock was obvious to all. He was well trimmed and to be blunt maybe only a few inches long. Ruth was laughing at his predicament and revealing to the world his little cock. Long story short he drank himself to sleep that night and I convinced Ruth there were better and bigger things to be had in this world. When I entered her she let out the biggest moans and her eyes glazed over!
Ruth confessed to me that she rarely felt Russ in her and that he had never conceived a child with him! She said from early on he liked his balls manhandled and she believed he could not conceive. I then took it upon myself to make sure that she and I risked the possibility every time we had sex. Finally at one point the condom did break and walla! To this day I don’t think Russ has fathered any child and Ruth still likes to see me on the side!
