I neglected to mention in my last comment about my wife and Gary’s affair that he had a wide cock that spread her tight pussy to its limits. However, my wife did enjoy its width because it felt wonderful and it kept his cum from oozing her pussy when he ejaculated deep. She was “into’ the concept of semen retention by that time and she savored the sensation of thick cum in her pussy. She especially enjoyed it when a lover’s cum was planted deep and it remained there for some time probably because of the risk involved with retaining sperm cells too long and the possibility of fertilization. She is definitely a “risk taker” and that turns her on.
My wife shared an apartment with her older sister when they were in college and her sister’s boyfriend spent a lot of time there. It didn’t take long for him to succumb to my wife’s flirting and it finally resulted in unprotected sex.. He was fucking her frequently without her sister’s knowledge and she was letting him cum in her pussy. When her sister found out about the affair, she simply told her to stop or she would have to move out. My wife stopped fucking Gary but not until he had already creampied her pussy dozens of times.
