Long, intense jerk.
This was about two hours long in total... with a break for a pathetic nap in between, interrupted by a phonecall. So I kept going. I was talking with one of my friends and being frisky, waiting intently for his responses... as soon as he sent a certain line, I totally lost it. Yup, we were that into it. :Þ I usually don't do such facial expressions upon orgasm.
