I Got Carried Away and Ended Up with a Yuri Harem

Yuri x Harem x Yandere Michelle Starium was reincarnated in another world. But now, a side effect of her magic is plunging her companions into pleasure and twisting their love into madness— Born with immense magical power, Michelle Starium grew arrogant as she was constantly doted on for her strength. While clearing a dungeon, the magic she unleashed had an unforeseen side effect. It carved an engagement crest onto her party members, simultaneously afflicting them with an irresistible pleasure. Once they tasted that pleasure, her companions gradually lost their reason, becoming helplessly dependent on and bound to Michelle. Before long, they mistook "affection" for "obsession," and fell into the abyss of a yandere's madness. "This is all your fault, you know, Onee-sama? For captivating me so..." "It seems I have no choice but to take you. No matter what it takes, I'll make you all mine." "Please be quiet. You're frightening Michelle-sama." "I-I've been... holding back all this time, too..." An angelic little sister, a cool-headed rival, a kind illusionist, and a cheerful best friend— Each of them, ensnared by pleasure, transforms into a yandere. ※Contains scenes with sexual content.
