My wife thinks I am cheating?

Ugly. Its one of the few situations in life where you are kind of screwed no matter what you say. You stated the facts, now it's up to your wife to believe you or not. If she has no real reason to doubt you, she will come around. But if you have a history of lying or cheating etc. well, you may be in for some ugliness.

why is that black bra of all the laundry under the bed? just come out already

Look her in the eye, and tell her the truth. After that, it's on her to figure out how to feel better. If she wants to drive herself nuts with paranoia and suspicion, oh well, that's her problem, not yours.

Y es that can happen, when i lived in a apartment I ended up having the young girls panties in our basket, lucky for me the wife was home all day helping me. either she excepts or she doesn't, her loss.

It was under the bed? How'd it get under the bed?

You are a word that rhymes with duct.You could offer to do a polygraph.

Well I know I don't believe you neither should she.

Maybe it her own but is playing games with you in order for you to confess other sins even though you are not guilty

Shes just going to have to weigh her decision you can't prove something that didn't happen.

Was she good?

Sounds plausible to me. So how is that other chick you're banging? Is she good in bed?
