I “accidentally ” slept with my MIL. So, my wife and my MIL are very similar in build, so much so that they are mistaken for sisters and even I have a time telling them apart from a distance (they even walk alike).

Seriously, there was a holiday at our house and I saw my wife and MIL coming down a dimly lit hall and it took me a bit to know who was who!

Anyway, last week, my wife’s cousin, the one they thought would NEVER get married, got married. A large, drunken time was had by all. Halfway through, though, the shrimp cocktail started working on my stomach. My wonderful wife offered to cut her evening short, but since my in-laws house was only 15 minutes away (compared to the 45 minutes to our place) my MIL and wife brought me to their house.

I distinctly remember hearing my wife and MIL saying that they were going back and I remember sort of aquiesing in my nauseous and drunken state.

So they get me inside (I’m 6’2″ and 260. Both wife and MIL are 5’5″ and 140) wife gets me undressed, cept for my boxers and down I go to nighty-night land in the in-laws spare room.

I’m not sure how much later, but I woke to a darkened room, without my glasses of course, because I heard the door open. My wife had come back to check on me. When she sat down, I couldn’t help but wrap my arm around her and pull her in for a kiss while my free hand ran all over her body. Big DD b**** pressed against me and with my drunk, horney self, pulled her down across me, onto the bed.

My hand goes under her dress and I was surprised to find no undies, wife isn’t one to go commando, but counting myself lucky that there was one less obstacle to navigate, I slipped a finger, then two into her warm, moist center. Her hands in the meantime, are pulling my c*** out of my boxers and we just go like rabbits! Drunken, uncoordinated rabbits…but rabbits nonetheless.

When we both had finished, I rolled over and started chuckling at how we hadn’t had s** on her folks house since we had dated, “OH, really?” came an answer from a voice that (no matter how much they may look alike, they certainly don’t sound alike) was unmistakably of my MIL.

I was in shock and I have never gone from a semi-drunk haze to stone cold sober in as few seconds in my entire life.

MIL explained that soon after her and wife got back to the reception, MIL offered to do a liquor run (reception was beer only at the table, but you could byo booze). My FIL said for MIL to go home and get the half-gallon of Stole and a 5th of JD.

She decided to check on me and when she saw I mistook her for my wife, she just rolled with it. We talked for a while longer and she left for the reception while I just sat in the spare bedroom, shocked at what had happened.

My in-laws and wife came back a few hours later, by this time I’d obviously sobered up and drove me and wife home. After making sure she was in bed and comfortable, I took the longest, hottest shower ever. My MIL doesn’t disgust me, she and my wife are two peas in a pod, but the sense of betrayal was hard for me to deal with.

Did I know on some level that it was my MIL I was screwing? Have I secretly wanted to bed her, too? I never thought about MIL that way before. How or should I tell the wife? It can only cause problems, but her folks visit quite often and I don’t want wife to see any weirdness that comes, too.

I know people will say it’s b*******, whatever, I know what happened, even if you think it’s a crock, what would you do?

Thanks for reading and for your advice in advance.
