Hanazawa An, a researcher who graduated from the medical department of a prestigious university. Intelligent yet exuding a hidden sensuality, her presence captivates everyone around her. Standing quietly in a lab coat, one hand holding a test tube, legs crossed, she embodies an erotic scene. Her appearance can be summed up in one word: beautiful. With a delicate face, large eyes, moist lips, and perfectly proportioned features, she mesmerizes all who see her. Her slender limbs and smooth, radiant skin would stop anyone in their tracks if they passed her on the street. As I fondle her breasts, varying the rhythm while sucking her nipples, she moans loudly, thrusting her hips wildly. Removing her thong, I gaze at her wetness—a small amount of sticky fluid trickling out with a soft sound. When I touch her with my fingers, they're instantly sucked deep inside. I stir her insides while licking her clit, creating wet, slurping sounds as I stimulate her inside and out simultaneously. Increasing speed and intensity, her moans grow rougher, echoing throughout the room. Looking up at the ceiling as she reaches climax, her expression of ecstasy is incredibly erotic—an unforgettable experience. No one who works alongside her, seeing her seriously devoted to research in her lab coat every day, could ever imagine her like this.
