Your Girlfriend is now a Thick Hippo Girl (Patreon)

You and your girlfriend are out getting some sun at the lake. She looks a little uncomfortable. She says she needs to sit down. Suddenly her boobs start growing. "What the fuck?", she says. She grunts deeply, "Uhhhghghh." You back away just a little bit. She closes her eyes tightly. Her nostrils flare wildly and then expand. Her nose and mouth start pushing outwards forming a wide snout. 

Her body is getting bigger, thicker - her thighs especially. Her swimsuit can barely contain her growing form. Her skin is also getting darker and changing texture. Her ears migrate to near the top of her head. People are starting to stare at you guys, drawn by the sounds of her moans and grunts. 

She opens her eyes. She sees how freaked out you are. "What the fuck just happened? Why do I feel so... different? I feel... heavy..." Her voice is noticeably lower. You pull out your phone and take a picture of her. You show it to her. She screams. "DELETE THAT!"
