Erin plays the sibling card

From Torg Adventure

Erin turns you again toward her. "Since you're my brother, I get you first," she whispers. She grabs your cock and strokes it a couple times, then pulls you toward her. "Please take my pussy. I gotta have you inside me tonight."

You roll on top of her as she spreads her legs. Molly and Auntie sidle up next to her and fondle her boobs. You line up your cock and lay it on top of her slit. You thrust a few times outside her pussy, getting your cock slick with her excitement.

"Oh, {firstname}. That feels so good," Erin says lustily.

"It'll feel even better inside you," you say with a sexy growl.
