After smoking some choice buds, I would conservatively say one of our sessions lasted a good 9 hours.
She came over after work around 5:30 p.m. and, after a drink and a fattie, we got right down to some foreplay, a nice prolonged oral session, then fucking. We must have gone through every position in human history over the course of the next 8 hours. We only took brief breaks for bathroom, more buds and a drink here and there.
We wound up stopping somewhere around 3: 30 or 4 a.m. because she had to get up for work around 7:00 a.m. I had to let her get SOME sleep!
I knew she would be back again after work for another round!
We both had the bigggest smiles on our faces, because the sex was just SO GOOD!
Also, she told her friends she could hardly walk the following day, but she couldn't wait to come back to my place for more, (who cares about not being able to walk if your pussy is soaking in anticipation?. I also found out from her friends she told them I had the biggest cock she'd ever had, and how she couldn't help but come back and get as much more cock as she could!
I made sure she had a VERY nice meal before we went at it again for yet another marathon session.
The whole idea is pacing yourself. If you're into what you're doing, you can go forever!
There may have been a quaalude, or two in the mix, which, in its day, would make things stretch-out for hours and hours. But, IT FEELS SO GOOD DOING IT!
