Sophia - the sister

"Sophia, Sophia" Jason mumbles.

She is the shortest sister, but she is also the bustiest. Her C cups look huge on her athletic 4' 10" frame. Not many would notice with her choice of clothing, trying her best to not stick out. Her long brown hair frames her innocent face with a cute button nose.

New Rule: Sophia Wesson's breasts will consistently and painfully inflate with milk and will double in size every six hours. She must be milked like a cow by hand to get her breasts back to their original size. only her sister Rachel can milk her.

Jason lifts the pencil and grins. It will take some time before they figure out how to get on top of Sophia's swelling tits. Hell, she might be smaller than her chest before Rachel gives her sister a squeeze. Speaking of swelling, Jason's attention is drawn to his erection. "I need to do something about this..." he thinks, and flips to the next page. Its time for another rule.
