A collab I did with  turner148 in July of  ElCid's Adrienne pumped full of water. Lineart by me, colors by them.

Adrienne wasn't the least bit worried when she found out that she was set against Celeste for an inflation match, the loser being the first to be inflated into a water balloon. She was certain she'd win, especially at her new fat size, and she was excited to see her opponent become a huge sloshing blimp. However, it turned out that luck wasn't on her side this time -- Celeste gained the upper hand, outmaneuvered her, and shoved a hose into her mouth. Before she could react, Adrienne was being rapidly filled with water! It wasn't long at all before the fatty dalmatian was a giant helpless balloon! After shutting off the water flow and being declared the winner, Celeste laughed and climbed onto Adrienne, using the balloony dog like a humongous water mattress.
