Quietly keeping secrets will only make things worse! Mako Iga, normally calm and reserved as a niece, instantly switches to erotic mode the moment eye contact is made, boldly demanding her uncle's cock with a tsundere attitude. In truth, she's deeply in love with him. "You wanted to touch me, didn't you?" she taunts, aggressively taking the lead. She teases her nervous uncle, who dare not make a sound, driving him to excitement before forcefully bringing him to climax. With an adorable smirk, Mako torments him relentlessly, secretly giving handjob and blowjob while he desperately suppresses his moans. The charm lies in her tsundere duality—the sharp contrast heightening the sexual tension. As full erection is achieved, their forbidden bond deepens, escalating into even more explicit intimacy.
