'Babe... what's happening to you?' - Cow TF (Patreon)

Your girlfriend said she wanted to show you her "true self." Cut to her groaning while her ass expands. Her body thickening up but somehow getting muscular too. Her fat ass pops her shorts off exposing her giant butthole at eye level. Now you hear her shirt ripping from her growing frame.

She snorts madly like an animal and then lets out a moo.

"B.. bb.... babe?" you whimper, stuttering from pure shock. "W... w.. what's happening to you? What the fuck is happening to you!?"
