The last few women i've known cum very easily, like every four or five minutes. This was a weird experience for me as my ex wife and my longest term girlfriend since both found it quite hard to cum. My 'skills' largely involved a mix of fucking for hours along with some hard learned oral and finger skills. The downside to both of these multi-orgasmic women is that they aren't very good at squeezing, which was a bummer for me as I found it quite hard to cum myself (though quitting smoking seems to be helping that), the woman I was seeing last year would start to squeeze and than cum almost imediately!, luckily, after she'd cum maybe four or five times her pussy would get incredibly engorged and tighten up anyway. The woman i'm with at the moment cums similarly easily, in fact, she's totally ridiculous. If we spend a long while on (pre?) foreplay, you know, just kissing, cuddling, stroking each other all over, then I get closer to her pussy, kiss and nibble her thighs, brush my face past her pubes*, blow on her engorged clit, she cums within 5 seconds or so of my tounge actually touching her clit. She also has the most incredibly sensitive (and easy to find by feel) G-spot, when she's turned on she can cum after maybe 20 seconds with just my middle finger. In fact, for the first few times we were together my cock seemed completely wasted on her and even now, she's only just getting into my ability to fuck for a long time, she'd rather have several 'quickies' a day. I've quit smoking and am trying hard to get fitter to make this happen. *completely untrimmed and a refreshing change after years of women shaved to look like little girls.
