Stepfather: Live-Action Edition

By day he's a gentle, loving stepfather—but by night he first claims the tsundere Elly, then slowly trains the innocent Sana until she's his. From peeping and sniffing to resistance and breakdown, to opening the door and begging for him, the sisters compete for his favor and fall one by one. The live-action Stepfather: a taboo household completely rewritten, and the stepfather's harem unlocked.
