[Satellites (Satetsu)] I Was Allured by a Little Demon and We Had Semen-Draining Sex [Panatical]

A wide-eyed demon girl with bat wings, a spaded tail, and a heart-shaped mark on her lower belly eagerly pleasures a flustered boy who worries they have to rush back to school. She shifts from playful oral teasing to a sloppy rimjob, declaring him her "Mano-chan" while her tiny stockings-clad feet wrap around him in a footjob. The encounter crescendos in his bedroom as she climbs on top, whimpering "Onii-san cum!" until he's thoroughly drained of his sticky nectar.
