The first girl I had ever been with was a "squirter," and, at first, I thought that shit was incredibly attractive.
But then she would soak the sheets, and it was kind of uncomfortable to be rolling around in sheets that are so wet you could wring them out into a glass. We tried to put a towel under her ass, but it wasn't enough, and so we'd double-up, but even that wasn't enough.
So eventually, we would just flip the mattress over after our sessions because it would soak through everything right down to the mattress and there wasn't much we could do about it really.
