Pantless, Mary walked to the box of vials. She was very conscious of the warm mass of flesh pressing against her legs, the way the udder conformed and caressed felt wonderful. A hand went down to fondle her teats. Mary moaned, losing herself in these new, odd but pleasurable feelings. After a minute of exploration, Mary opened her eyes and with a satisfied smile, looked again into the box of vials, a box of mystery and wonder. She wanted her udder to be bigger, much bigger. What would help with that? Running a finger over the vials and reading the labels, she picked out one here, one there and soon had a good handful of possible choices. With them she settled back onto her bed, propped up by pillows, the vials resting on her plump belly. Which to choose, she wondered, tapping a finger on her jello-like udder.
