15 years into a relationship the sex just disappeared, few months later so did the relationship. Funnily enough I can pinpoint the exact date.
had to get up early to attend a function as part of the wifeys dude hustle. She rolled over said she couldn’t be bothered with going, she went down on me (something she never did) then we had one of the raunchiest sessions ever, culminating in me taking her from behind and her cumming so hard she screamed out so loud (she was a silent fuck every time before.) that she woke the in-laws, She got up, walked down the corridor naked (past her mom) cum dripping everywhere to have a shower. The must bizarre session ever. She never touched me again after that. Either I fucked her up that bad, or it was “I’m done let’s try one last time see if I change my mind”.
Oh, so yeah SEX matters!
