In the dim light of their shared room, a curious sister sneaks a peek at her brother's showering form, her eyes widening at the sight of his enormous black cock. Unable to resist, she joins him, dropping to her knees and taking him into her mouth, gagging on his length. He growls, pushing her onto the bed and spreading her legs, his throbbing cock sliding into her wet, eager pussy. She gasps, her body tensing as he begins to fuck her hard, his huge cock stretching her tight cunt.
