Thank you for this sirmebane, this means a lot.
People often forget that the human is both animal and thinking being. We like to believe we control the animal but sometimes it gets the better of our intentions. Learn from the experience, know the warning signs and let your wife know when you feel like you're foaming at the mouth. Maybe she needs to make sure you don't go too long without some relief or just a little less stimulation.
Only the two of you can work it out for your needs. Take some solace that you stopped when you were asked and had feelings of remorse. The 'thinking being' assumed control as it should have so you're not out of control, you just ended up going a little too far.
Your point about me foaming at the mouth is not far from the truth. The animal part of my brain definitely took over, but you are right, as soon I was told to stop the thinking part of me returned, and very swiftly. I am confident that had she told me to stop at any other point I would have been able to.
As for the amount of stimulation I had received it was considerable, and spread over four days. It is without doubt the most intense period of denial, teasing and fantasy fuelled fun I have ever experienced.
I have been advised to talk to my Wife about the cuddling from someone who has experience in quite heavy BDSM practices. They saw this as a severe subspace reaction and saw my Wife's job as being there to bring me back down calmly and safely. This first experience was a shock for her as well, so we will definitely keep an eye out for the signs in the future.
