I don't think it was one thing, if your asking what my WG awakening was the closest I can think of was that Passion Patties Episode of Totally Spies, where clover gets really fat eating the drugged cookies. I just checked the clip and its different then what I remember, I think my brain combined the scene where she gets chubby and struggles to buckle her seatbelt on the plane with that one episode where her legs get swapped with bigger ones because I remember her being thicker in the passion patties episode and thinking the thicker thighs was attractive. So id say totally spies planted the seed but I wasn't into WG for a super long time it sort of happened gradually thru art. Fatfurs like volkenfox and Vdisco and gillpanda draw really great boobs and butts so I would reference them to improve the boobs and butts of my characters "thats how they get you lol". and eventually I drew a chubby Lisa as a challenge and she was super cute and super popular. Also when you run out of new BE art to look at you might take a gander at WG art that sometimes also has good huge boobs to get your fix lol so I think it was a slow slippery slope kind of thing to be honest that gradually happened over time, I still have a kind of love hate relationship with it and super picky about it tho.
