A man seeking efficient ways to find horny girls decides to introduce them through a woman named Lala, who has had many sexual experiences. One such girl introduced by Lala is Rara! She wants to try things she can't tell her boyfriend about, making it clear that this encounter is solely for sexual purposes. Although not wearing a cosplay, the badminton outfit she already has on looks erotic. When asked if she's ready, she shows off her red "competition underwear" as a sign of consent. Both parties are eager and active in their actions; he sucks on her nipples while also rubbing her large breasts. They use sex toys too, with simultaneous up-and-down action on both her nipples and pussy. He even gives her an orgasm using his mouth before finally penetrating her. As they enjoy themselves, Lala's husband unexpectedly arrives at the scene. Despite being caught off guard, Lala continues to pleasure herself while changing into another costume at her husband's request. The new costume showcases different styles of punishment for each phase of the moon. Meanwhile, her husband becomes aroused from watching and decides to cum on her chest instead of waiting any longer. With staff leaving and only the camera and the couple remaining, they engage in passionate lovemaking filled with kissing and grinding against each other. Finally, they end with the ultimate climax - a shared experience of normal intercourse resulting in a hot creampie finish! This NTR scenario proves to be delightful indeed.
