I identify as a foodie/feedie, but I can't deny I love playing the role of a submissive feeder to my lover--he doesn't put on weight, but stuffing and feeding him is absolutely wonderful!
I really love how it looks--his flat belly swelling out as he stuffs more food in, becoming taut and round--it's beautiful and sexy. It feels fantastic to run my hands over and feel just how strained it is. He's put on a little bit of weight during all the years we've been together, and I adore playing with the little layer of fat. It's so soft and pliable, very fun and sensual to touch. While he doesn't have a desire to gain weight and I like him just the way he is, we both enjoy the fantasy of mutual gaining--and I can't deny how sexy the idea of his flat tummy growing into a round little potbelly, straining against his shirts and pants is... I don't really know what it is, but the idea of his belly growing along with his appetite is just so appealing!
Plus as someone who is into vore--I love playing the role of submissive feeder trying to desperately feed a hungry predator so he won't decide to eat her instead. The thought of a predator with an overindulged belly also speaks of a certain success with past meals, and that's always nice.
I think most feedees have a little bit of feeder in them, and most feeders have a little bit of feedee in them!
It's just natural seeing so much pleasure in your lover's eyes, that you don't want to share it in something more than just vicariously.
