A unique project where Mayu, a female college student, sketches her senior from the same seminar while blushing shyly, investigating their romantic chemistry through art. The two appear as a serious, reserved upperclassman and the cheerful, adorable Mayu. As she diligently continues her sketch, her senior's cock remains unresponsive—until they proceed to a "grinding" retest. When his shaft is rubbed along her slit, his cock quickly springs to full erection. He then thrusts deeply into her pussy, and despite her shyness, Mayu keeps rocking her hips. The senior becomes completely entranced, thrusting passionately inside her, culminating in a powerful, copious creampie.
