I have a few! I'll try and list 20 turn ons:
1. Being confident and happy with being fat.
2. A seemingly bottomless belly.
3. Tight clothes.
4. Big appetite. Kinda goes with #2
5. A cute smile! This so much
6. Burping while stuffing. Especially when they're cute and she excuses herself
7. Stuffing
8. Belly play
9. Belly buttons! They're so fun to poke.
10. Button popping
11. Contrast. Since I'm thin, I love a contrast!
12. Dominant but not forcibly so.
13. Height. Not many girls are taller than 6'
14. A cute laugh
15. Hiccups. Especially when they make a belly jiggle a bit
16. Seemingly embarrassing belly gurgles.
17. Long tongues. Don't know why.
18. Moaning when stuffed.
19. Just being soft in general. Better cuddles.
20. Size comparison and progress
Filled all 20!
