The mysterious holes, hidden in the shadows, beckon the girls' fingers like a siren's call. They trace the edges, their breath hitching as they slowly insert their digits. The sensation is unlike anything they've felt before, cold, wet, and strangely alive. Their hands move in sync, fucking the holes with increasing urgency. Their bodies press against the wall, legs spread wide, as they grind their pussies against any friction they can find. The house seems to respond, echoing their moans and the wet sounds of their fingers in the holes, pushing them both to a spine-tingling orgasm.
