Arisu Otsu loves sex and gets an intense, deep itch inside her body when touched—when thrust into, her consciousness fades from the overwhelming sensation, and she can't get enough of it. While sex with her boyfriend feels good, it never satisfies her as much as what she sees in adult videos. That's why she sees this opportunity as a perfect chance—to experience wild, uninhibited sex like in AVs, and to feel pleasure so intense it completely shatters her rational mind. The thought of being filmed makes her nervous, but her desire to feel pleasure overpowers any hesitation. As soon as her body is groped all over or stimulated with a vibrator, she instantly moans out loud, unable to hold back. When the vibrator is taken away, she can't help but blurt out, "Why did you stop?"—her body craves the sensation too desperately. When her anus is licked while on all fours, she's overwhelmed by a mix of shame and pleasure, not knowing how to react. The vibrator feels incredibly good too; when it's thrust roughly from behind, her body instinctively reacts, making her utter filthy words like "Move it more." Penetration from behind brings a mix of pressure and pleasure, making her feel aroused instantly. And when the vibrator is applied directly to her clit, her mind goes completely blank in an instant, feeling as if she's losing consciousness. Her body tries to escape, but she's firmly held in place, unable to get away. This helpless state only heightens her arousal, making this the most intense and pleasurable sex she's ever experienced.
