I've had both types of experience. 1.) Top of my head blowing clean off, orgasms in waves (a real eye opener for a guy) and then having flashbacks for days after (what the....aa.., shit, errrr.... where did that come from?) 2.) Maybe another 20 minutes (and an inch of skin) and I'll... shit... Kill me. if. I ever. try. this aaahgain! Gawd make it staaaawwwwppp!
Sex or wanking... it's a complete crap shoot on the outcome.
The wife? She's good pretty much no matter what, popping off every 30 minutes or so... If I stop, her eyes'll roll back into place and she'll say, "Wha? tha's it?" Doesn't matter if it's 20 minutes or half a day...
"We done? D'jya feed the cat? Kids still asleep?"
Ya, I fed the effin' cat... Roll over an go ta sleep.
