I don't know why it is, maybe it's because I feel a bit insecure about myself, but I have always tried to pull the fat and ugly girls. Its not that I don't find pretty slim women attractive, but they don't do it for me. I don't get a twitch in my cock when some skinny 18 year old in a mini skirt walks past, (though she might look good) but if she is obese and looks like she has stopped trying, then I start fantasising about her.
I had a girlfriend a few years ago who I met through a friend on a night out. There were six of us at the pub, but when we joined them at the table it was Judith I noticed first. She was wearing a slightly frumpy dress, but I guess there isn't that much choice in her size. Her face was averagely pretty, but it was her weight that I noticed first. She never would tell me, but I guess she was about 18 stone, (250lb) and only about 5'5" tall. She also had massive tits, 44E which were one asset she would display. The evening went on and I chatted to her as much as I could, I discovered she was 24 and single, and had been for a while. There came a point where she finally realised that I wasn't just being polite to the quiet one in the group, and that I was trying to pull her, when we were in the nightclub (the Leadmill for those who know it).
She realised because I had drunkenly groped her tits while we were dancing together. She smiled and asked if I liked them, and I told her almost too enthusiastically that I thought she was incredibly fit and horny. We slipped away from the others and found a quiet corner. She was quite happy to be very nasty considering we were still in public. We kissed, then my hand found her cunt, and I was fingering that under her dress. I think my other hand was on her tits, squeezing and playing with them.
I suggested we went back to my flat, as I lived quite close at the time, and we were back there by cab very quickly. That night was a blur, but I remember being surprised and turned on that she didn't shave herself at all, and had a hairy pussy, with hair trailing up to her navel and down onto her inner thigh. She had stretch marks on her tummy and her huge tits sagged down onto her stomach or almost to the bed when she lay on her back. She had nice wide areolas, something that really turns me on.
More importantly I got to fuck her, without a condom, and she seemed genuinely turned on by my decent length and significantly fat dick. It felt so amazing pumping my sperm into her soft body. I felt unattractive, by comparison, but she didn't seem to feel like that.
