A wife troubled by a problem she couldn't discuss with anyone discovered a veteran AV director known for solving many women's problems on SNS. Summoning her courage, she contacted him, leading to a direct conversation with an experienced man. In the case of 36-year-old wife, Mikako, whose husband's sex life was unsatisfying, she developed a fetish for public sex after witnessing it on a train. When the director suggested a public sex play, she agreed immediately. Blushing but with a melting expression, she received caresses, had her pussy licked, and climaxed with shaking legs. Inserted from behind while standing, she writhed as if on a train, and in the cowgirl position, she moaned, "This... this feels good," grinding her hips until she reached ecstasy. Changing locations, she experienced continuous spasmodic orgasms with toy torture. Begging for another penis insertion, she felt the size and came intensely.
