“You wanted to suck my boyfriend’s cock, Anna, so I’ll help you out. Get it all the way down, you fucking slut! Swallow that cock you’ve been trying to take from me!”

Anna gasped and moaned around the cock invading her slender throat. She wondered if her sister was angry or having fun.

“Are you sure you want to do that, Sara? I mean-”

“Shut up! My sister wanted your cock, so she’s getting it. She’s going to be your little slut until she learns her place and you’re going to fuck her however, whenever, and as many times as I tell you to.”

“Yes dear.”
