No sensation is more thrilling than your pushing you cock into your wife's just-fucked-by-another-man pussy. You will instantly feel the difference—looser, wetter, sticky perhaps, but definitely used. (I swear I have been able to feel her soreness after a rough pounding.) One time, however, didn't yield the usual sensations.
I always asked my wife the same two questions after she been with another man: how many times did he cum? How many times did you? Often, she would just signal with her fingers the two numbers. This time, as she returned home, she finger gestured two followed by three. Wow! Often she didn't orgasm at all with this fellow, and he was usually just good for one orgasm (late 40s). I was so looking forward to giving her a good reclaiming fuck and feel her less-than-faithful vagina, a vagina filled with someone else's semen. Not this time; no wetter and only a little looser. I had to hear all the details.
They started by her sucking him, followed by him fucking her, moving on to 69 position, where they both orgasmed. He then wanted to watch her masturbate, so that he might pick up some moves to better please her. She did it with him watching closely, right between her open knees, which made her feel too self-conscious, so she asked him to insert his cock in her mouth while she would finger herself. She came quickly, and then he came in her mouth for a second time, which prompted her to orgasm again. None of his semen had been deposited in her vagina, sadly. Well, sadly for me, as I loved soaking my cock in another man's load. Since I was happy that she came three times, I didn't mention any of my disappointment at encountering a less-sloppy seconds.
