Aftershocks.

I'm finding that after I have a really intense orgasm--or series of orgasms--God I love my life--sometimes it's not over when it's over. There's a period of time afterwards when my brain is fried and I'm hypersensitive. In a sense I'm still coming, even if nothing is touching my vagina. I can't think; when I talk, it'll be either nonsensical babble or extremely specific directions on how to touch me. I have, I am consumed by, a tremendous drive to be touched. Everything touching my skin--everything, even the sheets beneath me--feels amplified a thousand times. Pain does not feel much like pain at all. I want to make out and I want to be struck.

I am not much use during this time. I don't have the energy to move; I probably won't be sucking or stroking your cock and I definitely won't be riding you. But I am tremendously, exquisitely reactive to anything you do. If you ever wanted to just stroke your finger across a girl's shoulder and have her moan and squirm like she's getting deep-dicked, this would be your chance. (Actual deep-dicking during this time may produce highly volatile results. Further experimentation is warranted.)

This seems to be a relatively recent thing; I don't remember it happening when I was younger. It doesn't happen every time, even if the sex was great, and it almost never happens when I'm alone. But as strange and amazing and wonderful experiences go... yeah, it's pretty awesome.
