After the bathhouse experience, my wife didn't follow-up with additional training for awhile. Then one weekend, she invited my brother in law to visit and help with some chores around the house. I had just had knee surgery and was unable to cut the grass and rake leaves. My brother in law, Jim, had recently divorced my sister and he told me that he was frustrated because his dating life had failed to restart.
About midnight of the first night, my wife decided that she was horny and wanted me to play. I was stuck lying on my back and really wasn't into it. After idly playing with my cock and balls for a few minutes, she gave up and conceded defeat. Just to see what would happen, I told her that Jim was on the living room couch and that he was probably as horny as she was. To my mild surprise, she started grinning and whispered "I'm gonna do it!" She got out of bed, buck naked, and left the room leaving the door open so I could listen to the proceedings.
After a few minutes, I could hear some grunting and I knew that she must have started on Jim. Later she told me that she walked into the living room and caught him rubbing his cock. When he saw her and noticed she was naked, he asked her to give him a hand. She used her mouth instead.
After about a half hour, she padded back into our room and gleefully jumped on the bed. "Do you know what I just did?"
"Tell me about it" was all I could respond. My cock was becoming very firm. Instead of recounting the activities, she crawled up my body and straddled my shoulders with her knees. As she bounced to a halt, I felt a warm drop of something plop onto my neck and I knew what she had in mind. She told me to open my mouth and she slowly lowered her gaping cunt to my mouth. Before hitting bottom, several drops of juice hit my face and tongue. There was no mistaking the taste of Jim's cum.
I licked her cunt until it had emptied itself of the load that Jim had deposited. My cock was so hard that it hurt. Donna proceeded to back down my body and simply kept going until my cock was gripped in her sopping wet cunt. Then, she proceeded to tell me how Jim had thrown her over the back of the couch and took her from behind. At the same time, she very slowly raised and lowered her hips and ground against my root and balls. Between the story and the grinding, I soon blew a massive load. She quickly jumped up and covered my face again. As soon as my tongue touched her clit, she came wildly, spurting a mixture of her cum, my cum, and any of Jim's cum that happened to be left inside. I drank it all down.
