Feederism and cuckold fetishes combined
​
As the title says, I have combined 2 fetishes. after gaining from 165 pounds to 440 pounds, I've gotten too fat for my girlfriend, and she sees other guys now. Getting too fat for things is extremely hot for me, especially when it's getting too fat for people in my life. I've gotten too fat to hang out with some friends, too fat for the activities they want to do, and of course, I've gotten too fat for my girlfriend and too fat to fuck her like I used too.
So now, I as I'm eating all day, she's going to the gym with her boyfriend, and I'm too fat to do anything about it. I've got myself addicted to food, and all I do is eat. At this point, food is my sex. I'm too fat for normal sex, so stuffing my face as my girlfriend goes out with her boyfriend, is the closest I can get.
The situation is endlessly hot to me. It is embarrassing and humiliating, but embarrassment/humiliation just makes me eat more. Which just pushes me further into the situation I'm into.
