Hina and Atsushi are a couple with an age gap. Atsushi is a shift leader at a beef bowl restaurant, and when he went to help out at another restaurant, he met Hina and fell in love at first sight and started dating. They spend their days going to each other's houses and getting cozy with each other. They create a lovey-dovey atmosphere at work, and are an officially recognized erotic couple with warm eyes from those around them. Atsushi is a slutty sadist who is always teasing Hinano, who speaks in a cute Hina, because he wants to see her flashy reactions. He can eat three beef bowls just by looking at a restrained woman. Hina doesn't like being punished, and she likes being made to cum, being humiliated, and anything that feels good. But even Hina has ambitions... While researching adult videos to please her beloved boyfriend, she learned about "slut play" for the first time. A woman who is always treated like a child and teased is no good! I'm at an age where I want to grow up, so I'll become a slut and make Atsushi moan! Just as I was thinking that, my sadistic boyfriend counterattacked me in an instant! I was tied up to the bed, my sensitive ears and neck were tormented and I was made to moan, and my already hard nipples were teased and tormented. My pussy was already flooded with water. Atsushi's big and hard cock was thrust deep into my vagina, and I was made to cum over and over again with sadistic intense pistons! "Now it's my turn to blame you!" While my coworker was filming me, I tried desperately to make him cum with a slurping blowjob, but he betrayed me and I was tied up again! "No, no! Why does it have to be me?" Even though I screamed, Hina body was honest, and in the end, I was made to cum as usual and was exhausted. Next, I was forced to wear a rabbit costume and was subjected to a deep throat and spanking training play. She writhes in agony from intense cunnilingus and choking sex, and finally gets a creampie. "Tomorrow is the day... tomorrow is the day Hina will be the slut..."
