You don't want to fuck your wife because she's not attractive anymore. You love stroking your cock for me, cumming for my ass over and over again. She's not good enough for you, she can't fuck you right, she can't do all the things I can. You want me and only me. You want to stroke you cock for my ass. Do it. From now on you're going to refuse her every time because every drop of cum is mine and only mine !
