Chastity and orgasm denial discussion

Yes, a friend of my wife and discovered by accident. Along with Chastity, we do some bdsm every couple of months. It was a cold Saturday afternoon and the wife was going to punish me for a list on minor infractions. She had me tied spread eagle in the living room wearing only chains, nipple clamps, cuffs and collar, heavy leather bondage hood (with only nose and mouth open, headphone to also deprive me of my senses, and my 2 3/4 inch metal cock cage. Next to me on a table were floggers, whips, and of course her strap ones and lube. After clipping me all in nice and secure, she went to take her hot shower and dress in one of her domme outfits. At that point I knew I was in for a long afternoon and all I could do is reflect on my misdeeds and what was coming. Just after she got in the shower, her best girl friend from college (they were and still are an item, dropped by because of some difficulties she was having with her new boyfriend (she is a divorced empty nester). Since I was working on a project in the garage, both our cars were parked in the driveway so she knew were were home. After trying the doorbell a few times and since both the wife and I could not hear it and respond, she decided to walk around the house to the back door to the mud room. When she tried the door, it was unlocked and she let herself in thinking we were in the kitchen. After a few times calling out, she was concerned and came into the living room and got the shock of her life. Even with the hood on, she knew it was me and never expected us to be this kinky. She thought she would have some fun and rubbed her gloved hand across my body and then started to examine my cock cage. I had no idea it was not my wife and started to be for mercy from my loving mistress. Slowly she moved all around me and I was getting more and more stimulated waiting for what came next. She grabbed one of the floggers and slowly rubbed it across my body and then gave me a few light slaps with it and tried about 3 other punishment devices before my wife came out of the bedroom all dressed and ready. When we think back and relive the story, not sure who was surprised more, but it ended up to be a very interesting afternoon and still a secret between the 3 of us. I would gladly share that story in a fowwowup, but will leave you with this. She ended up taking one of our old cock cages and gave her cheating boyfriend an ultimatum, put this on or hit the highway. A week later she had us over for a drink and guess who was tied to a beam in the basement naked and wearing a cock cage. The three of us admired her handywork while her first started to yell and then whimpered to be let free. She had planned on breaking up with him, but wanted to put him in his place for what he did.
