Abby straddles you, riding your back like a cowgirl to make sure you maintain your pace, a little faster but not enough to edge or cum. You can feel Abby's pussy rubbing against your back, sliding over you easily. She pushes you even deeper into Julie.
ABBY: Come on slave! Make Julie cum, I want to hear her scream.
JULIE: I'm so close...so close...I'm on the edge...
ABBY: Grit your teeth slave, she loves pain, it makes her cum so much faster. Don't stop, I want to see her orgasm!
JULIE: AHHHHH! I'M CUMMIIIIING...YEEEEEESSSSSS....OHHHHHHH!
