I have a long time friends/couple. Whom my friends wife hits on me often while we're playing tennis. She'll flirt with me in front of him and he will just smile. I'll say something back in a joking way. My friend will just laugh. I've never paid any real attention to this. But as of just the other day while playing a match where my friends wife and I were paired together to compete against another team. She kept touching my arm in a very gentle way. Like with just the tips of her fingers. Then she just looks directly into my eyes when we talk. I love that... oh let me describe her to you real quick. Five foot six. Long blonde hair. She has to be a 34 D at least. Very long legs, tanned and very tone. She is about 115-120 Lbs. Anyway. A couple of months ago while on court with her husband. She had asked if I would give her a ride home. Because her husband was going to have to go somewhere else after we played. Her husband said it would be a help to him if I could. So I did. On the ride to her home. She was touching my arm again. Then not to long ago. Her husband was out of town and we had a tennis party to go to and she asked me to escort her to the party. I did. Arm touching again. Her husband/ my friend also. Asked me to take care of her while he was gone. My question is this. Are my friends secretly swingers. I would love to have a 3some with them. I don't know about seeing my friend dick. I was told he has a big one from her. So how can I ask him/ her if there swingers. I would hate my life if I were to offend them or lose there friendship. But I'm very curious now. Please advise. Thanks in advance.
