Hi, shhh, we don’t want anyone to hear us, do we? I know what I’m about to do with you is going to seem very naughty….and it is. Not every mother-in-law would give their son-in-law a blowjob but I know what a prude your wife is. I’ve become, shall we say, very close with her other boyfriends and they all told me what a bore she is in the bedroom. I’ve even broached the subject of teaching her a thing or two, but she gets embarrassed, and says things to me like, “not every woman is a slut.” Well, I am. I love big cocks. I knew the minute I met you that you had a really big dick. I could see that you needed a woman who knows what to do with a cock, not some tepid girl who shies away from anything remotely kinky. Does she still only fuck with the lights off? I know that you want to fuck me because every time we have a get together you glance at my tits and ass every chance you get. I would be shocked that you married her but I know you fuck other women. So, instead of whoring around with some strange sluts that you might run off with someday, you’re only going to fuck me from now on. You look shocked. Well, would you rather be able to come over to your mother-in-law's house and get sucked and fuck whenever you want, knowing I’ll never tell? Or would you rather sneak around and wonder if someday you’ll get caught and your wife will take half of everything you own? That’s what I thought. Now relax and let me suck this big dick until you cum in mouth. Yes, sweety, I swallow too. See, now you only need to fuck your mother-in-law when you want to cheat from now on.
