I've been with 2 women that have squirted from intercourse (and I love it).
My first could only squirt while on top. She would grind for a while and then the floodgates would open up. I remember the first time it happened (also the first time she squirted and also my first), we must have been going at it for almost an hour when she mounted me since we were both getting tired. I knew there was something special about that girl when i met her, even if it was her body that got my attention. She was around 5'8", only a little shorter than i am, long legs and had some amazing tits to go with a really tight pussy. I think they were 38D's and she always dressed them up for me. Needless to say, I didn't mind when she rode me since I would be burying my face into her tits. Anyways back to that fateful night. I could always last a good while with her and she was riding me slow and hard on this occasion which really helped build up the dam that was about to break. She had some long hair which was flopping around all over the place as she moaned and groaned like a cat in heat. This went on for some time and it was almost like I wasn't even there since she was so focused on riding my dick. Finally, it just started to pour out of her as she continued to fuck me as if nothing was happening. I wasn't even sure she knew what was going on, maybe she couldn't feel it, but I sure could tell since I got a nice warm bath of her juices. We were left in a puddle and had to go to her place that night to sleep....
The other is my wife and I don't share her
