I can't believe it's actually successful... I summoned a succubus to lose my virginity, but it ended up possessing the class idol! From then on, my school life quickly turned into a life of milking semen with no way to escape! Even though there were other people on the train, she sucked my semen with a blowjob! She forced me to give her a handjob during class and swallow it! She also attacked me at home and had sex with me inside! Every day, I was milked until I couldn't cum anymore by the pussy of the girl I admired, as her own semen tank! And after collecting my semen, she returned to her original form! I was no longer allowed to cum inside anyone other than her...
