"Hey, do you think sex feels good...?" Yuka, at an age where she's becoming acutely aware of her sexuality, asks her childhood friend, Yu. Some have already had their first experience, and she can't help but feel a sense of urgency... Unable to contain her rising emotions, she suggests, "Let's have an AV viewing party today." Watching sexual acts together intensifies her feelings, making her feel both aroused and incredibly embarrassed to be in the same space. "Should we... try it ourselves...?" They hesitantly explore each other's bodies for the first time, their awkward touch and eventual ejaculation marking each step towards their shared sexual awakening.
