Feederism is a kink built around the dynamic of one partner, the feeder, encouraging another, the feedee, to eat and gain weight, with the weight gain itself often serving as the erotic or emotional focus.
For many people involved, the appeal lives in the care and indulgence of feeding someone, the surrender and sensation of being fed, or the visible change in a partner's body over time. It overlaps with fat admiration and body worship, but the active, ongoing act of feeding is what sets it apart.
Worth knowing: Because rapid or extreme weight gain can carry serious health consequences, partners are advised to talk openly about limits, pace, and medical wellbeing, and to keep consent ongoing as bodies and desires change.
Also called: feeder, feedee, gainer, weight gain fetish, stuffing, mutual gaining, fat admiration, belly worship
