Sharing my wife's mouth
My wife asked me if she could watch me and one of our single friends mastrubate while she kept her clothes on and just watched us.
I told her that we could try it so he came over one evening, and after several drinks she told him that she wanted to watch him and me get naked mastrubate while she watched.
She was pretty drunk and told us that she wanted us to both rub our members on her lips at the same time.
Then she took a hold of each of us and started rubbing the tips of our members against her tongue and against each other in her mouth.
Then she watched as she gave us both hand jobs with our penises touching together until I felt his hot semen all over me.
She licked his semen off of me until I exploded in her mouth, then she took turns sucking both of us until we were both spent.
This happened frequently when my wife and I were in college. My roommate eventually admitted to me that he was gay (early 90’s and people weren’t as open as they are today). My wife, girlfriend at the time (19f), loved knowing she could walk around naked in front of him. She enjoyed watching him and me jerk off, while sitting next to each other. It was a huge turn on for her and he enjoyed the attention.
