Your feedee milking cow girlfriend is begging you to milk her. Her chest is leaking milk and she promises her chest will grow even larger after getting milked.

"Ugh- my chest is so sore and they feel so full. You said you’d help milk me and I’m getting full to the brim. I’ll moo for you the whole time, just the way you like it- ONLY IF you promise to feed me until I pop after. And besides, you know that whenever you milk me, my chest grows exponentially. "
