Third-year university student Tachibana Marina smiles sweetly during an interview, revealing she's part of a wind instrument club and proudly boasts about her talent playing various instruments. However, her circle consists entirely of girls, leaving almost no opportunity to discuss romance. Struggling with uncontrollable sexual desire in her youthful body, Marina gradually reacts to the man's touch, squirming her hips with growing arousal. Experiencing everything for the first time, she lets out intense, genuine moans as she feels the thick cock inside her. The interview flows naturally into action, progressing into kissing, nipple teasing, and full-body licking. She explores pussy play, wet handjob sounds, cunnilingus, and handjobs—eventually having her first-ever squirting orgasm. She eagerly licks the man's nipples, performs passionate blowjob, engages in 69, missionary, cowgirl, doggy style, lying-down doggy, and even the matsuha-kuzushi position. The session includes cumshot in missionary and creampie cleanup. Her pure emotions, mixed with nervousness and excitement over these first-time experiences, are vividly portrayed.
