I wouldn't call it a "catch".....but rather a pleasant surprise the first time it ever happened. We were at a Carolina Friends party, when they used to have them at The Gentlemens Club in Charlotte. I was preoccupied trying to line us another couple up to play with after the party, as it was an off premise type place we were at. I got to missing her, and found her in the clubs VIP room with 2 guys who were regulars with their wives at the parties, just like we were. She was on her knees, sucking 1 cock, then the other. When I came in, the guys got a startled look on their faces since we knew of each other, spoke and were friendly, but never buddy buddied around. I put my index finger up to my lips, and motioned for them to keep on. I was behind her and she had no idea I was there. My cock got harder than Chinese arithmetic, so I pulled it out and eased in beside one of the guys. She took mine in turn with the other 2, and sucked it 2 or 3 times before she realized it was me....lol. She finished us all off, and we shot cum all over her tits where she had her top pulled down. I think she caught us instead of vice-versa!
