It's happened to me before, and just happened to me last night. I had brunch with my friend this morning (quite a sexually-experienced friend) and told her about it. She said she's never experienced or heard of anyone experiencing it. So here I go to ask all you lovely people about it. The orgasms I usually have are very intense. They usually take 5 minutes or so of steady stimulation and I'm well on my way. If he really does it right, I'll have an orgasm so intense that I can't think or talk for several moments, and sometimes the feelings are so intense that I start to cry. I'm not sad or hurt, but several times I've let out a few sobs. It's not flattering but I think I'd have to be crazy to be embarrassed about it. These usually come after I've already orgasmed a couple of times, and has always happened when he's entering me from behind. I "ball up" a little bit and I always tell him to go as hard and as fast as he can. It's a mix of intense pleasure and a little pain, and the end result is primal and explosive. When I have these orgasms, if he keeps going as fast and as hard as he can, I seem to cum as long as he's still going. If I feel like I'm about to have one, I'll yell at him to "Fuck me through it," and he'll go as hard as he can until he comes too. It usually doesn't take too long as we've usually been having sex for a while, but last night I had already given him a blow job, and one earlier in the day, so he was raring to go and kept up for what felt like 2 or 3 minutes. It's hard to explain, but I can't really even remember what happened during that time. I just remember having the feelings of that incredible orgasm for the entire length of it. I was aware I was screaming and I know where we were, but everything else is a fog. Afterwards, I usually can't speak or move or do much of anything besides let my legs spasm and catch my breath. My teeth usually chatter for a while too. I haven't talked to any other girls who this happens to and I'm kind of surprised considering the number of people I've tried talking to about it. So ladies, has anything like this ever happened to you? Guys, has anything like this ever happened to your ladies? What's the most intense orgasm you experience and how long does it sustain for?
