Fattening others

I am in a relationship that recently became long distance. Unfortunately, I also only recently started accepting that I am VERY much turned on by my partner's weight gain. How do I encourage that and start stepping into my hopeful role of feeder for my wonderful Fiancee? Any tips and tricks would be appreciated

I'd suggest video calling and directing your partner on what to eat or just even watching and encouraging them as they do. It may also be fun to send them high calorie recipes or snacks, this could be another video call opportunity where you could talk while they cook before your virtual feeding session.
