You replace Mary

From Torg Adventure

Your blood is on fire with lust. Seeing Gwen come on Mary's tongue has you wild with the need to take Gwen and make her yours. You and Julie both move at once toward the two sisters. Julie pushes Mary down on the floor, and straddles her face. You've never seen Julie so dominant.

You gaze at Gwen, and she licks her lips and smiles at you. You urge her body onto the couch and climb on top of her.

"Mary told me what happened at your house, and I got so turned on that I asked her to go down on me. If you can nail your sister, I can nail mine."

"And I can nail you," you say, as you rub your cock up and down her slippery slit.
