Riya, the sultry sister, catches her brother Kapil asleep and can't resist the urge to explore his manhood. She gently strokes his growing cock, feeling it harden in her hands. Kapil stirs, waking up to find Riya's skilled fingers wrapped around his sensitive flesh. Their breaths hitch as they lock eyes, the tension between them palpable. Riya leans in, her tongue flicking out to taste her brother's pre-cum, igniting a fire within him. Kapil grabs her hair, guiding her head as she eagerly sucks him off, her moans vibrating against his shaft.
