[KURUBUSI-KAI (Dowarukofu)] Loli Bakunyuu no Imouto wa Onii-chan to Ofuro ni Hairitai

A bubble-bath fantasy unfolds between a flat-chested little sister desperate for her big brother's attention and the shy older sibling who can't resist her innocent invitation. Beneath the running water and clinging foam, her tiny body betrays an unexpectedly massive, heaving bust that bounces and overflows with every trembling touch, escalating the sibling bath into a heated first-time encounter. Watch the brother's careful restraint crumble as his adorable imouto moans, squirms, and ultimately begs for release, leaving them both drenched in more than just bathwater.
