[Gamenhaji (Noji)] Nanakadashi SeX!! [Tigoris Translates]

Two sisters, one brash and teasing, the other shy and stammering, corner their brother together in bed, whispering that they've heard everything about his habit of finishing inside—calling him a "nanaka-chan" and daring him to keep up with both of them. The action escalates rapidly from groping and breastplay to a full, dripping creampie for the older sister, climaxing in an intense x-ray finish as she gasps "I'm cumming!!!" while the younger one happily tends to him below. A steamy, playful sibling threesome charged with jealousy, teasing, and unapologetically messy climaxes.
