Katie wants pussy too

From Torg Adventure

"Kaitlin, I'm sorry I took this rat bastard from you," Katie says. "But aren't you glad you didn't marry the asshole?"

Kaitlin says, "Thank you, Katie. Apology accepted."

"As a small measure of my remorse, come over here and I'll make you come," Katie says, licking her lips. Kaitlin gasps and then giggles.

"That would make me happy, Katie," your sister says as she trots over to the other side of the bed, she shoves Richard over a foot or so, making him groan, and lays next to him without touching him. There's plenty of room for Katie to go down on Kaitlin as well as ream Richard's bowels. You look at your sister, and she winks at you as Katie lowers her mouth to Kaitlin's sex. Her hand on the carrot slows a little, but once she starts munching down and Kaitlin starts moaning, her hand resumes its previous rapid pace.

Seeing Katie give your sister oral sex gets you going, and you pound harder into her tight pussy.
