In a quiet household, siblings Evandro and Doka find themselves alone, their eyes wandering, desires unspoken. Evandro's gaze falls on Doka's plump lips, her innocent yet enticing countenance. Doka, sensing his gaze, licks her lips, her tongue darting out, a tease. Evandro's cock twitches, and he can't help but imagine those lips wrapped around him. Doka, noticing his bulge, feels a warmth between her thighs. They're drawn together, their breaths ragged, as Evandro whispers, "Chupa, Doka." She obeys, taking him in, her mouth working his length, her tongue swirling, as he groans in pleasure.
