Our Little Game (sick Game)

We are a married couple with an age difference. I am a 38yr old guy and my wife is 25. But there is also another difference. My wife is tiny, 5-10 and maybe 90 pounds. And she looks like a teenage girl. People often assume she is my daughter.
Well we are swingers and meet singles and couples for sex. We both laughed about it the first time we met another couple and they kinda freaked out thinking she was underage and I was her dad. We actually had to show them her ID before they would have sex. After that we kind of developed our own twisted sense of humor.
We would specifically seek out males, females and couples and when we got behind closed doors we would introduce ourselves as father and daughter. You would be amazed how many people got super turned on at the thought they were having sex with my teenage daughter! Both men and women!
