I did that today!
Startled the hell out of me. HAs never happened before, but today, I had a fairly intense scene where I spent an hour or so tied to a chair with earplugs blndfold and gag getting whacked in a totally unpredictable pattern.
I had a whole string of mind-blowing orgasms, totally lost it, spasming all as much as I could, considering I was very firmly tied down, and then all of a sudden, liquid.
They were very intense orgasms, but I'm not sure I'd say the squirt added anything to it, except a bit of a puddle on the chair. Do most women find that the squirting just goes along with more intense orgasms? I've gotten the impression before that ejaculation itself is pleasurable, and I didn't find it to be. It actually distracted me. although I guess I can blame that on this being the first time it's ever happened.
The guy was quite pleased with himself.
