“Trying To Find Out Which One Has The Biggest Cock To Suck And Fuck…”

This has been true for a while. My wife fucks his boyfriend two or three times a week, while we fuck once or twice a month. She acts as if everything is the same, but she's been behaving in small but meaningful ways that indicate she considers him her primary sexual partner. She never says no to me, but she does things to avoid sex with me a couple of days after she's been with him, as some sort of being faithful to her man. It's very arousing, but also dangerous...yet I can't being myself to stop it.

adults only, of course
