[Kakashi Asahiro] Garden of the Goddess Ch.1

A shut-in NEET whose average day consists of eating, browsing the web, and jacking off gets the shock of his life when a winged, dark-skinned goddess descends into his bedroom, and his very first divine wish is a harem to combat declining birthrates. With heaven's reluctant blessing, he takes revenge on the sister who always looked down on him, forcing her to her knees for a tearful deepthroat before bending her over and vowing to turn her into his anal slave while keeping her a virgin. By the end, the regretful goddess finds herself dragged onto the bed beside his worn-out sister, flustered and exposed, as he cheerfully promises a couple more loads and the harem strategy rolls on.
