My wife and I have had many mfm over the years. One time that I'll never forget. We had been chatting with guy for few weeks. He was going to be visiting our area on business trip. The night we were to meet up, my wife started her period.

We met up with him at bar and had few drinks and chatted. When topic got around to going back to his hotel informed him about wife condition. Obviously we were all bummed out as we were looking forward to it. We left and while we were driving home my wife mentioned how excited she was and wondered if guy might be interested in anal. I called him and he said great so we went back to his hotel.

My wife ended up laying on her back on bed with tampon string showing as we took turns fucking her in ass. It was great.

Next day I talked with him and he said he ended up in hospital ER due to thinking he was having heart attack! Said he was so excited and his first time doing anal and couldn't calm down. Wife and I felt horrible about but never forgot that night!
