I Lit a Lewd Aroma and a Disaster Happened.

YouTuber trio Asukara Natsuyasumi—Makoto, Mizuki, and Rui—finish an ultra-spicy yakisoba challenge, then light a lewd aroma for their next project. Under its effect Makoto deep-kisses Mizuki, Rui joins while masturbating, and the three escalate into a threesome of kissing, nipple and genital play, and anal fingering. In the living room, Makoto becomes aroused watching Mizuki caress Rui on the sofa and masturbates; urged by Mizuki, Makoto has anal sex with Rui, after which Mizuki proposes a threesome to restore subscriber numbers and the three penetrate and caress one another to climax. Flashbacks show video production and a YouTube debut request; after a 100k-subscriber celebration, intense threesome sex resumes as Kazaoka Makoto, Saotome Mizuki and Shikura Rui continue a fierce threesome on the bed with penetration, fondling and deep kisses. After climaxing covered in semen and fluids while kissing, Makoto explodes that the footage cannot be used for their channel; Mizuki suggests saving it for a year-end special, and the three drink, order pizza and late-night delivery, sit together on the sofa and settle back into ordinary life.
