When I first got with my now fiance (she was 19), we had pretty good sex until one night she was really horny and on top of me. I only have an average sized dick (just over 6 and about 5.2 circ).
As she was really going for it, I suddenly felt all this wetness. It was quite dark so I wondered what the hell was happening. I'd never had a squirter before. She was moaning so much I thought I'd hurt her, then she just collapsed onto me. She told me 10 minutes later that she'd never had an orgasm up until then, and she didn't know what was happening either. It turned me on so much, and still does thinking about it. After that night, she used to squirt every time we had sex. Once, we were in a park outside and she was sat on my face as I licked her pussy. She squirted so much I nearly choked on the juice. No bullshit! I agree the taste is slightly different, but I couldn't get enough of it. Unfortunately this squirting didn't last forever and even though I try nowadays, I can't seem to help her squirt anymore. 5 years on though, we still have great sex.
