Is your girl a greedy fat pig overeating on sweets and fast food? There's a number of things you can do to her to humiliate her and I promise it's gonna be as much fun as fucking a beautiful skinny bimbo. Fat girls usually have weak personalities: if they didn't, they would have enough discipline to say no to food. Their low self-esteem makes them perfect objects for degradation, abuse and ridicule.

If the girl agrees that she is fat and ugly, she's gonna accept humiliation easily as a way of making up for not being thin enough for you. Deep inside she knows she deserves suffering to punish herself for overeating. Use it to your advantage straightaway and degrade the bitch with no mercy:

• make her to write things like "fat pig", "so huge", "binge eater" on herself before she comes to bed;
• make her say things like 'I'm sorry for being fat', 'I wish I was anorexic', 'I hope I'm gonna get an eating disorder and start looking pretty' while you're fucking her;
• make her try on size 0 clothes in front of you and make fun of her that they don't fit;
• make her eat junk food and watch Fashion TV at the same time, and keep talking about how weak she is and how much she would love to be skinny and pretty;
• make her pose for photos with some unhealthy food in one hand and a fashion magazine in the other;
• make her jerk you off to pictures of anorexic girls;
• make her slap herself on the face as many times as she has pounds above 70;
• make her grab her huge fat belly with both hands while you're taking pictures of her;
• give her compliments like 'You're quite pretty, for a fat girl' or 'Wow, you must have lost weight, you almost don't look fat anymore';
• embarass her in social situations, e.g. by saying 'Are you sure you should be eating this? Isn't it a bit above your calorie limit?' when you go out to a restaurant with friends. 

If her self-esteem is a bit higher and she may not accept this kind of treatment straightaway, you have to be more delicate at the beginning. You may try the following to make her feel less attractive and too fat:

• confuse her with contradicting messages about her body, tell her how much you like her the way she is, and later the same day hint to her she would be so much prettier if only she lost a couple of pounds;
• buy some clothes for her that you know are gonna be too small, but pretend it was your mistake and say something like 'That's OK babe, you don't have to be fit and thin like the typical pretty girls';
• take her to a very elegant designer clothes store pretending you want to buy her an expensive dress, only to discover that nothing is gonna fit her, as the top designer dresses are not manufactured in such large sizes;
• take as many unflattering pictures of her as possible but pretend you didn't want to and it's all your fault, say something like 'Oh I just suck at taking pictures, I just can't take a good picture of you, one can always see your belly rolls and muffin top, I guess I'll enrol on a photography course'.
