This AV masterpiece depicts a sweet yet stimulating cohabitation life with Ria, the friend of the protagonist's sister. The interaction between the shy protagonist and Ria, whose excitement is fueled by alcohol, keeps the viewers' hearts racing. Especially, the kissing scene starting from the Pocky game showcases Ria's cuteness to the fullest, making one unable to look away. Afterwards, the sight of Ria gently coaxing the amateur virgin protagonist is irresistible. The depiction of Ria enjoying sex with a smile and the protagonist's fully erect penis in response is truly magnificent. The final creampie scene in the cowgirl position allows one to enjoy the beautiful, perfectly shaped breasts of Ria bouncing in 8K high definition. The protagonist's stamina to keep ejaculating and Ria enjoying it adorn the climax of this work. The production quality by KMP VR is commendable, offering a work where the unique realism of VR can be fully experienced.
