Tensei Neet no Isekai Harem Seikatsu

"Choroin" is the only spell capable of breaking the karmic bond with the demon race. Using this spell, the protagonist has sex with the hero in the bath, engages in "big sister" play with the magician, punishes the doubting priest, and indulges in whatever desires he pleases. What effects does this spell unleash, and how far can its erotic potential go? This is the story of a jobless, unemployed NEET protagonist who, after reincarnating into another world, builds a harem of beautiful girls tailored to his liking. (Source: DLsite, translated)
