Sometimes when I give my lover a really intense orgasm, or a prolonged plateau orgasm, with my tongue or fingers, she'll break out in uncontrolable laughter. Anybody else ever have, or seen, Laughing Orgasms? It's also interesting that she got an elaborate branding/cutting, partly to test her tollerance for pain. She has less tollerance for pleasure, it seems...
Sometimes if my hubby keeps at it for too long, I get super, super sensitive, and well, it tickles, which in turn makes me giggle. Usually I just stop him before I get to that point though.
I do break out in laughter at times when I come, as the feeling is that incredibly mindblowing beautiful, that it kinda erupts all out, like, something inside me opens up and if I don't yell my lungs out with joy, I laugh. I dunno why sometimes yes and sometimes no, I let go completely in general when having sex, but that laughing mostly happens when he teased me for ages, like then it's a rush of finally fulfilled anticipation and sheer joy he finally soothes my aching to come. Beautiful...
