While her cousin is busy dusting under the bed, her enormous, round ass is eerily exposed, taunting me with its plump, inviting curves. Unable to resist the temptation, I sneak up behind her, my heart racing with anticipation. She's wearing nothing but a tiny thong, and I can see her pussy lips peeking out, glistening with her arousal. I pull down her thong, revealing her tight, puckered asshole, and without hesitation, I plunge my rock-hard cock deep inside her, fucking her doggystyle while she moans softly, trying to keep her cleaning chores going as if nothing's happening.
