I was hooked the first time. We started as swingers. The very first couple we hooked up with I had a hard time focusing on the other lady because I found myself so interested in watching her and the other guy. It was totally unexpected too. The first time I saw her lips on his cock... damn. While we still played with couples, we started to do more mfm threesomes than anything. She likes to have me involved so i don't typically just watch, but I can participate and focus on watching her with him! The first time she had a cock significantly bigger than mine was another turn on. Watching him stretch her and her struggling to take him in her mouth... damn.
