Wonderful pair of hangers, you can sort of feel the weight of them. Actually that’s something I really like, holding a good pair of tits and feeling how heavy they are. I don’t know the medical reason, but some girls have big tits that feel like baloons, while others have tits that have some substance. I’d imagined tits to be mostly fat, but some seem to be full of air. I’m not a doctor, but I’d be interested to know why this is?
