[Suitekiya (Suitekiya Yuumin)] Tanoshii Jian Hassei [nemdiggers12]

A faceless older man builds a devoted harem of young girls, starting with sweet Yuna who eagerly services her beloved 'Onii-chan' and declares him the thing she loves most in the universe. The camera keeps rolling as a bratty grade-school girl who insults him through the wall secretly masturbates to his touch, her body filmed with timestamp overlays while she squirms. By the end, he sits surrounded by a sprawling group of round-bellied girls, each one carrying his child in this escalating harem fantasy.
