Mary, mostly cow now and with a gigantic udder sits on the floor. Rob kneels down and gently lifts Mary and sets her down on her side. He can't believe how much she still weighs. Mary groans as her weight is shifted. Her giant udder and teats stand out proudly and taut. Four teats protrude up at a 45 degree angle. The teats proffer themselves to Rob.
Bending over, Rob gingerly touches one of Mary's teats. She lets out a low moo and Rob starts. With a gulp Rob encloses one warm teat in his hand and squeezes. A warm spray of milk erupts from the teat, hitting Rob squarely in the face. Mary moans and moos as she is milked.
Rob squeezes a few more times, getting himself coated in warm milk. Another squeeze and another spray of milk in his face. This was getting annoying. Rob bends over, with his face next to the teat and hesitates before placing the teat in his mouth. Rob can feel Mary shudder as he does so.
Pausing for just a second, Rob then begins to move his head up and down Mary's teats, squeezing it and releasing a shot of milk into his mouth that he quickly swallows.
