My wife found us a girl

For a few years now my wife expressed her desire to eat pussy. I told her I wouldn't mind but I'd like to be able to at the very least watch. Last week we were in a park hanging out. We saw this young woman who was very attractive and had long thin legs. I said to my wife, there's a nice piece of candy I'd even do. My wife said let's see. She went over to talk to this woman and ten minutes later they came back to me. My wife intrduced me to Gina and said Gina would like to play with us. We went back to our home and I sat there watching my wife and Gina going full speed on each other. I got hard as hell watching my wife eat Gina out.Gina wanted to eat my wife so they changed position. After several minutes Gina told me to fuck her. My wife looking at me smiled and said go on, do it. So Gina is eating my wife while I fucked her. She was enjoying the whole thing then my wife told me to stop. My wife rolled her over and sucked her clit, the girl was moaning loud, my wife made her cum. Gina rolled onto her side, I put my dick in her mouth and fucked it and came on her face. I didn't expect her to taste it but she did. I asked my wife if she came and said oh yea that was good.
After the sex we took Gina to a nice tavern for some food and drinks. I asked what she wanted, a coke. I said no booze? Oh no she said I'm only 19. I was floored, I thought she was mid 20’s.
This was my first threesome and my wife and I loved being with that girl. I hope to see her again soon and so does my wife. The girl was no sex amature and had experience with women.My wife said Gina knew what she was doing and did it very well.
