"Do the challenge, bitch," echoes in her mind as Paisley, the sexy American-Canadian-Aussie mix, strips down and starts fingering her tight, hairless pussy. Her big ass bounces with each thrust, her moans growing louder. Unbeknownst to her, her stepbrother watches, stroking his hard cock. When he finally reveals himself, she's mortified, but her body betrays her, her nipples hardening, her pussy dripping. "You like being watched, don't you, Sis?" he taunts, his eyes locked on her glistening cunt.
