I don’t know of such a thing exists but it’s a great idea. I had a female wingman for the first time in Brazil recently and it was kinda great. We had banged earlier in the evening as agreed and she had to get back to the club. I suggested we could go together and she could be my wingman to find another hottie. Far from offended, she engaged in the task with gusto. She was of course working the crowd looking for guys but also on the lookout for me.
When I found my hottie there was sure to be a line for her affections (She just finished the sexiest table dance I’d ever seen!) My girl asked if I liked her and I said I did. She said “I’ll go get her”. Sure enough she snagged her at the ladies room and brought her over and the rest is history. It was awesome!
Now my experience is a little weird because I banged my wing-girl first. But I think the general idea of a wing-girl is great. I would surely pay a couple hundred $ for wing-girl services. of course it’s a slippery slope if she is even moderately hot. You are bound to become attracted if you spend time together.
