Hmmmm, how did he react? When we went to bed, he was sober. When I awoke and wondered what was going on, he was stumbling around, looking at himself in the mirror, kind of prancing, looking down at himself, and his arms were in motion (kind of like he was trying to fly). Evidently he awoke and decided to have a few beers and just prance around in me undies! He picked the fanciest available. So, I don't think he really acknowledged my disbelief, he eventually went back to sleep. He had a rather difficult time removing them though, as his but is larger than mine and it appears he was having a really good time.
I asked him about it later, he tried to ignore it, and he said that he just wanted to wear my panties. I discovered the bra on a later date rumpled in the closet with dirty clothes.
Oh, my, I almost forgot, I had an exact set in black and found them later, stretched out too!
