Birthday viewing

Me and my wife had my buddy over for my birthday. I was pretty sure he was the one that found my wife's panties behind the door in my last story. We were all drinking alot but my wife really got wasted. She had some very short shorts on and she was "accidentally" flashing her black panties every time she moved. I caught my buddy looking at her opening in her shorts many times. I could see he was getting turned on by the large outline in his pants. As it started getting late my wife said she was going to bed and walked into the house. I told my buddy I was going to make sure she was alright and followed after her. When I got to our bedroom I could see she was already about passed out on the bed so I helped her out of her clothes and half covered her. I purposely left her black panties on display and left the door partially open. I went back outside and told my buddy we should go inside and watch some TV. I gave him the seat that was right across from our bedroom so hopefully he could get a good look while I watched him. I turned the lights off and the TV was lighting up the walls and part of my bed. As we sat there for about an hour I caught him staring into my bedroom and he was rubbing himself trying to b quiet. I was getting turned on watching my buddy playing with his dick looking at my wife. After awhile he excused himself and went to the bathroom. I will have to remember to leave a pair of her underwear in there for next time. I got up and looked through the door and saw what he was looking at. My wife was on her stomach with one leg up and her black underwear were pulled into her meaty pussy. After he left I went to the bed and pulled her panties out of her pussy and slid it to the side and fucked her for just a few minutes before I cum inside. I pull out and cover her sopping pussy with her panties and go to sleep. I'm going to see what she thinks about a threesome. We have never had one but I would love to watch her cum on another cock....... I will keep you posted.
