Tiffany is kind, and a bit slow on the uptake.

“Yeah sure. I don’t need this much anyway,” Tiffany says handing the cum-filled mug over to her big sister.

Sophia eagerly receives the mug and takes a sip. She savors the taste and the sensation of her little sister’s cum flowing into her mouth and down her throat. Then she takes a bigger gulp. Tiffany watches the semen dribble from the side of Sophia’s mouth as she drinks. Just then Tiff has a thought, and she quickly takes back her mug.

“Wait wait stop! Don’t chug the whole thing!” Yells Tiffany.

“Wha…what’s wrong?” Sophia asks.

“I think I should put a few more traps around the house,” Tiffany explains. She looks into her cup and swishes the contents a bit. “Maybe enough for a cup or two?”

Tiffany makes her way downstairs and Sophia follows right behind her. She walks into the living room and thinks about her plan. Sophie heads for the kitchen and returns with two more mugs. Tiff takes the cups, pours some cum in each, and leaves one on an end table. They then go to the kitchen and leave the other on the table. Tiff then turns around and sternly faces Sophia.

“Alright Sophie! No more messing with my traps! I’ll let you know if I want you involved in any of my experiments, and you’ll follow my exact instructions,” commands Tiffany.

“Understood! I won’t cause any more trouble,” declares Sophia.

Standing in the kitchen Tiffany realizes that she hasn’t eaten yet and her hunger is catching up to her. She thinks about making herself a meal, but she worries about how much time she has left alone with Sophia. Tiff gives her mug to Sophie and instructs her to put it back in the bathroom. While her sister is gone Tiff looks in the fridge for something quick. She grabs a half-empty carton of orange juice and chugs the whole thing. Sophia returns as Tiff throws away the carton.

“When are Mom and Em coming back?” Tiffany asks Sophia.

“Probably in an hour or so I guess,” Sophia replies.
