No, it's impossible. She's fat... yes! fat girls will be a lot better than skinny girls. you have less change of hurting the girl. and they have big boobs! and they are going to want you more. and they are better to cuddle with after sex. and you wont lose them.

that depend on the boobs of her mother, grandmother... if they have big boobs is most likely that the girl could have big boobs
Men like the look fo your boobs and some think that the bigger they are the better, but if a guy really cares anout you, he wont care what size you are. Someone once told me that men are just naturally drawn to them, so if you catch someone staring at your boobs, its not their fault unless their trying to come on to you.
Boobs !! ;p Especcially Big ones the bigger the better. But fake boobs are unnatural.
They're embarrassed because if they know other girls have bigger boobs than them, they feel like the girls that have bigger boobs are better and more attractive than them. If that's not the case, then maybe they think their boobs are too big. I don't know... You shouldn't be embarrassed about how big your boobs are. 
my guess is squeeze them and lick the nipples. put your dick between them, i dont know! why are you even asking??
if you have big boobs, good stomach, little over average butt, and if you have a sexy face. another reason to have big boobs is that he can grab them during sex so more pleasurable time for a girl. its also good for him to feel. that also a reason for the butt. for him to hold onto it. have a good time sex!!!!!
