I’ve had a few sugar babies that I did this too. I didn’t even think it was considered a “kink”. But I guess it is. Usually while in doggy, I’d pull their hair and I’m not talking at the end, but I always go for the back of the head, for some reason that really gets them going. I mean I can instantly feel her pussy get super wet, even more so than it was prior to putting my hand on the back of her head and pulling her hair. Then after a short while I move to the neck and wrap my hand around her neck, (not choking by the way, but on her neck and my grip is a little firm, but not tight - its hard to explain but its a fine balance). When I do that, based on their reactions, its all over. They typically start cumming, fucking me by bouncing back on me and beg me not to stop.
But I can see where something like this takes a lot of trust with your partner. But I also don’t choke them either. In fact, one SB asked me to choke her harder, and I was afraid I’d choke her too hard. Afterwards, while we were cuddling, she showed me how and where to place my hands on her neck for maximum effect without hurting her. That of course, led to a lot more fun times later
