Is this cheating

He probably intended to have sex with her, which is why she was probably drunk and he wasn't. & I'm sure he walked into your bedroom to check if you were actually asleep. People are vulnerable when they're drunk.

Yeah.

1. He walked in to see if you were sleep. If he wanted to make sure you were okay he would have came closer and looked at you.

2. Why outside in the motor home? If he was concerned about her warmth, he would have kept her in the main house.

Your husband was going to rape your drunk sister while you slept. He's an asshole.

Drunk or not, they made a decision to take it to the motor home away from you... tbh. If this was the first time they had been intimate they would have been facing each other probably kissing and passionate.to spoon and allow your self to be spooned is quite a relaxed,intimate /trusting thing....not something you do with strangers (love strangers or first times) just my opinion I'm sorry but I don't this was the first time. I could be wrong. In future though,never leave your drunk lover with another woman...take him to bed with you or send the other person home

Alcohol lowers people's inhibitions, they are more likely to engage in behavior which they won't do if sober.

Jeez.. Its totally wrong... Can't u see ur husband is clearly cheating on u with ur sister... Just let ur sister get out of ur house n ur life or divorce ur husband..

Ask that bitch if she remembers and question him some more also and regardless call Maury he'll give em a lie detector and sort it all out.

Ditch the husband for 6 months and help your sister your probably right she must've been to drunk to remember so I suggest you going with your sister somewhere to distance yourself from your husband for a good 3-6 months ( stay with relatives?) I'm not saying leave him because he'll probably come crawling back for your mercy but show him who's boss and in charge.

Totally inappropriate and I'm sure they both know that. Drunk or not, there's still a thin line from spooning with your sisters husband (or your wifes sister). Disgusting on both of their parts.

None of these opinions really matter, because all that really does, is what he has to say. Whether he comes clean, defends himself, lies, e.t.c., you should be communicating with him. There may be a honest, truthful, and sober explanation to all of this. Your recollection of the occurring in that night sound tired, accusatory, and vague, and a bit caught up in the drama and emotion of it all. Remember why you got with him, and try to understand his perspective, so you can further see what actually happened. Perhaps it was drunkeness that got the best of him, or perhaps your sister lead something on. Only you know them, and what they would do. So follow your instincts, be honest with him, and don't get caught in the drama. Because, after all, you really don't know.

What you saw may have not been cheating but based on the position they were in and your husband's reaction, had you not shown up they would probably have been fucking.
Also I'm not sure from your story how long you were asleep, there's a chance they could've already fucked and redressed before they went outside.

In any event I would have a hard time trusting him after this if I were you, even if nothing happend your husband and sister both put themselves in a very compromising position.

She sucked his cock and licked his nuts.
He fucked her in her ass and then she sucked his dirty cock and ball bag until they were clean.

If they did have sex, and didn't involve you, I would say its cheating I guess

Of course it's cheating don't be naïve. Your husband is a little cheating prick

Busted!

Was the husband drunk?

It ain't cheatin if it happens in a motor home. Also, it ain't queer if you are dressed as a woman.

Tough one. I'd question him a little as well as your sister. Guys typically lie though and since your sister was wasted I'm not sure you will get any answers. But if you suspect cheating, this probably isn't the first time something has happened. Fins a guy you don't have to worry about and move on.

not cheating, but still not right.

Drunk? If nothing serious happened or this reoccurs just forget about it. It's still wrong though so he should apologize

It's ok
