[Djqn] Succubus-Lesson

Part-time tutor Kasimoto Souta thinks every lesson with his gorgeous honor student Takamine Narumi is a dream gig—until she binds and gags him, cooing that he is now the prey of a succubus who eats men after making them smaller. Twenty minutes of her drooling, tongue-slathered attention shrinks him to pocket size, and her plump lips part to gulp him down into a cavern of towering teeth and slick, gripping flesh. As she thanks her sensei for helping her pass the exam with one hand resting over her rounded, bare stomach, he splashes helplessly in her churning depths, screaming that he doesn't want to die.
