The subject of this first shoot is "Runa, 21," a university student majoring in mechanical engineering. Contrary to the rigid image associated with her field of study, she has a soft, fluffy appearance and irresistibly cute mannerisms. During the interview, she answers with nervous, wide-open eyes. Despite her highly attractive charm, she has no casual sex partners and has only dated two guys in her life. She's been pleasuring herself alone for a while now, and shyly admits her motivation for applying: "I haven't had any action lately... so I've become a little curious..." She blushes cutely whenever the camera moves closer. Gentle bird kisses gradually melt her expression into one of bliss. As her clothes slowly come off, her plump, fair, and tender skin is revealed—flawless up close, as pristine as freshly fallen snow. Her marshmallow breasts, a perfect pink as expected, react instantly to the man's tongue, filling the room with her lewd moans. When his tongue moves down to her lower body, she trembles in small spasms and cums twice. On all fours, she provocatively thrusts out her peach-like ass, squirting uncontrollably—an image of pure eroticism. Once fully turned on, she drops to her knees on her own, taking the man's cock deep into her throat with loud, slurping sounds. Then, with her arousal peaking, the man thrusts deep into her pussy. After pulling her panties aside, she quickly cums in missionary—the position she claimed to love most. "Aaaaaaahhh! No! No! I'm cumming!!" she screams, nearly shrieking in ecstasy, her F-cup breasts bouncing wildly as she rides the waves of pleasure. Pounded hard from behind, her plump body undulates with repeated orgasms. The first spanking of her life gradually reddens her ass, creating a filthy, erotic scene. After experiencing sex for the first time in a long while—and sensations she's never felt before—she ends the session in a dazed state, absorbing the man's cum, a deeply memorable finale.
