My wife shocked me last Saturday night. She had her lover Jason over, and he had brought his friend Mark with him (not their real names). She usually is just with one lover at a time, but occasionally she enjoys two men. We both know Jason and Mark, and I knew they were both coming. Well, they had been going at it for some time, and I was listening and masturbating from the other room. She is always very vocal when she's with two guys, but this night she was unusually vocal, with grunting and pleasure sounds. Because this was a little unusual I opened the door and peaked in. They had my wife tied up to the bed posts. We have a four poster bed and her hands and feet were tied to the posts. I was shocked! We had fooled around with tying her up when we first started dating, but it didn't last long and it went nowhere. But there she was all tied up and obviously enjoying it. Jason was on top vigorously thrusting, and Mark was kneeling near her head vigorously masturbating. Her mouth was open and her tongue was out. At that moment Mark came and unloaded a waterfall of cum onto her face, on her hair and into her mouth. She was slurping it down as fast as she could. Mark must have saved up for a week to ejaculate that much cum. Right then Jason bucked and started to cum. Jason finished but kept thrusting and then my wife came with a strong and beautiful orgasm. This whole scene lasted about a minute. I had timed it perfectly. I had been masturbating while I watched, and after my wife came I immediately came. They never saw me peeking, so I left them in their post orgasmic bliss. Afterward I asked my wife if she had ever been tied up before, and she responded that she had and that she likes it. I was shocked. News to me. I love my hot wife.
