[Lunaluku] Sca Sis (Ougon no Sonata XXX Vol.1)

Two bratty, twintailed schoolgirls with pantyhose-clad legs scheme to drag their unsuspecting male landlord into their filthy weekend plans, gloating over his stained underwear as they prepare to unleash their "scat play." The volatile duo, buzzing with anticipation and breaking wind at will, corner the bewildered guy on the train before dragging him back to their apartment for a very messy introduction. Things only get more degrading from there as the girls, still in their pleated uniforms and skirts, take turns indulging their grossest appetites on him in a haze of lewd laughter and foul odors.
