[RudySaki] My Life as a Succubus Ch.14

Ayumu, a pixie-cut demon girl turned succubus with soft breasts and a flushed, trembling body, lives completely devoted to Shun-chan, clinging to him and breathlessly begging for his cock to cum inside her while confessing her love. That tender, sweat-slick intimacy shatters when Shun-chan turns his gun on Lyna and binds them both with a Demon Seal that seals their magical power, insisting he must kill the monster and take Ayumu to confess his sins so they can be together happily. Just as he prepares to fire, a crack tears open and Lyna's towering Demon King father steps through, enraged that a puny human dared hurt his daughter and ready to make him die, until Ayumu's desperate plea reduces the death sentence to a Stone Curse.
