BigButt:
What I've recently noticed: Her genitals seem to start getting really squishy.
Her butt and hips seem to broaden quicker than usual.
Ah yes, the FUPA. Nice to hold. Very sexy in its own right
BigButt:
We've recently started to eat breakfast, which means she (we) consume About 500 kcal more a day than before. Roughly.
Also I've started spiking her breakfast and other meals with a spoon of vegetable oil whenever I can. So that'll be 80 kcal extra in the morning.
Go for other replacements too, like heavy/whipping cream instead of milk.
BigButt:
She doesn't know about it and I feel bad about it, but everytime I see her seemingly bloated belly, her broadening hips or her thighs I cannot but want to do this.
I know what you mean. FA quickly becomes Gaining Admirer; the growth itself is fun. Growing them is fun.
You can toy with just letting her know. From your first post I see you have weight conversations kind of matter of factly, so just let her know; "You look really amazing like this; I think I'll boost your calories for a while"
