[Erostellus (Miel)] Onii-chan I want to go in too [Full Color] [Kappasa]

A cheerful sister catches her brother heading for the bath and begs her way in with him, still dripping in her little bikini and grinning like she's already won. Once the steam takes over, she teases him mercilessly—working his shaft between her soft armpits and chest, laughing that her pits got him rock hard while he pleads with her to hurry up. By the end she's glowing through a face and chest plastered in cum, looking thoroughly pleased with herself and in no rush to let this sibling bath time end.
