Okay, after reading your post, I had to rethink that experience. Saying "12 hours straight" was misleading. He did cum at regular intervals, so we had to pause and change the condoms. Then, he was ready to go, again, as was I. I must have been fertile, b/c I was def. not sore that night...which is uncommon for me. I value the pain...it proves I'm actually being fucked. (I'm masochistic like that.)Happyfeet and Amygirl, it's only b/c you haven't come across me yet.
I am with Chrys on this - large cocks and prolonged penetrative sex are not easy bedfellows unless the lady is built to match. That's my experience anyway - this isn't a bad thing as you can then do a lot of other things (I don't like the to use foreplay as a concept) which make for a richer sex life than wham bam thank you mam.
Just last night, I was "all fucked out", but TM was still ready to go another round...I couldn't because I was sore! Oh well, it happens sometimes.
But today I'm horny as ever. And still sore. Damn!
