Fat experiences

I've been my bf's feeder for 3 weeks after he finally voluntarily consented.
I made some dreadful mistakes in the first week but still have so much to learn.
I'm looking to make friends with people in a similar position and advice from experts.
His CW 210
my GW for him 300-350

first of all, welcome! i'm glad your bf is open and ready to gain weight for you, as a feedee myself with experiance with female feeders, as long as you are constant it will be okay, but what kind of mistakes you talking about?

omg in the first week. I was telling him to eat, so dumb, I'm lucky it didn't end the project.
