Fattening others

My girlfriend is aware of my preference to feed a partner and encourage them to gain weight. She has mostly just ignored it and hasn’t really engaged but has occasionally made a comment during sex about her big belly (which definitely isn’t big).

Would it be inappropriate for me to give her a gift of a certain amount for every pound gained? My initial thought is $50 per pound which I’d reward her with for every 10 lbs gained. Maybe increase the amount after the first 10 lbs so $500 for 10 lbs, $1,000 for the next 10, etc.

Depends. Do you want a transactional relationship that depends on you being a cash cow?

Also, this seems to me like an attempt to build soft power over her. If she is desperate for the money she might decide to gain without wanting it.

That’s a fair point. I guess I’m just trying to find a way for this kink to work for both of us because it’s not really working without it.

She does have some submissive tendencies which was why I thought this might work. The feedback I’ve gotten here makes me think not though!
