Hazuki and Miria, siblings bound by blood and a shared secret, find themselves in a cramped, dimly lit closet. Their bodies press together, hearts pounding with a taboo desire. Hazuki, the elder, traces the outline of Miria's stiffening cock through his jeans, while Miria tentatively reaches for Hazuki's breasts, cupped in a lacy bra. They're halted by a creaking floorboard, their father's voice echoing outside, but their lust is undeterred. They continue, fingers exploring, breaths ragged, until they're interrupted again, leaving them panting and yearning for more.
