Mary's milk tastes wonderful and Rob can't seem to get enough of it. He sucks hard and fast, swallowing the warm milk. Mary moans as she is emptied. Over the next few minutes, Rob keeps milking Mary. He passes being full and keeps on sucking. Rob's belly becomes distended, giving him a milk gut.
The stream of milk is quickly gone and Rob is left licking drops off Mary's flacid udder. Rob sits back and sighed, "Wow, that was incredible! I never thought cow's milk could taste that good."
"Glad you liked it" Mary said laying down with her cow legs under her. Rob reached over and patted her head. His fear and shock of the whole situation had dissipated, and he was now accepting it. Even enjoying it.
"Urp!" Rob suddenly burped and blushed. "Oh, excuse me!" Mary laughed, something between a moo and a girlish giggle. Rob suddenly hunched over, clutching his belly in discomfort. Mary half-rose in panic, but could do nothing but watch as Rob began to change.
