Last night, I was in a MFM threesome with this lady friend of mine and one of her guy friends. I was on top of her and pumping away when she suddenly winced in pain. I asked if she was okay. She said she needed a breather and asked me to pull out. We returned to cuddling for a while. Then she asked the other guy to go in. He put on a condom and lube and entered her. No pain this time. He pumps until he comes. Seeing how I haven't come yet, and would really like to, I ask if she wants me back in. She says I'd be too much for her. She said I'd be too thick and too deep to be comfortable. Sounds odd to me since I've had sex with her plenty of times before. Including some really active thrusting before where she took all 8 inches in. She also said she likes the feeling of being filled by my girth. His cock was about average length and width and she didn't complain of pain when he was inside. In the past, when women have said my cock caused some discomfort, it was usually in the first moments after entering them the first time. But this women had taken my entire cock several times before. How many other women have had experiences like this? Did a big cock feel wonderful one day and cause discomfort or even pain another day?
