Tis all started a year or two ago. The wife and myself had been out with friends having a few drinks. When we got home things got heated up. We love to tie each other up and get rough with one another. As things progressed we started having sex and she asked me to put my hands around her throat and choke her. I was kinda suprised at the request. But I done as she asked and started to choke her. We kept doing our this and she started to return the favor and as we had an ****** we released each others neck and seemed to intensify the affect it had on us. Now it's an on going thing. Several times after an intense event she would wake up with a sore neck. On occassion I've had her start slapping me in the face as I choke her, what a rush. Sometimes I will walk up behind her shove her against the wall or counter and act like taking her from behind and place my hand around her neck and it seems to get her going. It seems to get more intense the more we practice the technique. I would be willing to do more but still trying find our thresholds or boundaries. Suggestions wanted.
