Succubus Yondara Haha ga Kita!?

In an enthralling tale of forbidden desires and unexpected encounters, Morita Takashi, a high school student with a voracious libido, embarks on a quest to lose his virginity. Struggling to gain popularity among girls, he finds himself drawn into the world of succubi - sex demons that satisfy his deepest desires. Upon receiving a mysterious message proposing a summoning ritual, Takashi takes up the challenge and commits to abstaining from masturbation for 72 days before casting the spell. But the consequences of his actions go beyond his wildest dreams as Erin, a succubus he summoned only once, starts appearing in the most unexpected places - under his desk while studying, as a tutor, even in the pool under the sun-drenched sky. The lines between reality and fantasy blur when Takashi discovers an intimate mark on Eri, his mother-in-law, hinting at their secret trysts fueled by otherworldly encounters.
