So, last night my wife, who is mostly on the vanilla side, says to me that maybe I could cum tonight. Yeah! Awesome idea being a month and a half into this lockup! She has me lay in bed and ties me to all four corners. Whoa! What's this? She rarely ever wants to tie me up. She leaves and a couple minutes later returns with my estim that I usually use for my back. She placed one patch on the bottom of my sack and the other on the top side of my metal cage. "Let me know when it really starts to feel good and before it hurts". She messes with the control until she dialed in on that sweet spot. "There, that should get you to cum in no time. I'll check on you in a bit". She set it for 6 seconds stimulation with 2 seconds of rest. It really felt amazing, and after about 20 minutes I could really feel like I could cum, but at 6 seconds and the brief rest, all I was getting was a tease. She came back in around the half hour mark "Hey. How's it going? Cum yet?" "No, it's almost there but 6 seconds isn't quite doing it". She then says "Let's see what we can do about that" as she messes with the controls again. Shorter duration but more stimulation. She leaves again and will check on me in a bit.10 minutes in and I am right about to cum, but no. That rest in between isn't letting it happen. I'm right at the edge for what felt like hours, but was only about 20 minutes. " Cum yet?" she asked when she returned. "No Ma'am. I'm right there but that break is killing it for me". "Ok, we'll make a little adjustment and I'll be back". That adjustment wasn't any better, as I was still on edge. My only saving grace was I knew she would be back to check on me in a half hour. Wrong! It was just about an hour she returned. *Not finished yet?" with a slightly irritated look and a slight smirk at the same time. "I'm getting tired of running up and down these stairs to constantly check on you". She adjusted the controls once again, but this time was a lower setting, that I knew wouldn't have me go right away. "Maybe this will help you along" as she pulled something over my face. Ooohhh I know that scent! It was her panties she had been wearing! "Enjoy smelling my pussy all over your face. Hopefully you'll cum this time. I already have in those very panties on your face". She leaves once again, and even though I have her scent with each breath and a constant tease on my balls and caged cock, I still am stuck right at the edge. Desperate! This duration lasted 2 hours! She returned, took her panties off my face and turned off the estim. As she untied me she says "Well, I gave you 4 hours to cum and enjoy my panties, but you didn't. Looks like you'll have to wait until I'm feeling generous again". 4 hours! 4 constant hours of edging! I don't know what got into her, but I love it and fear it all at once!
