The tsundere and voluptuous employee, Risa, has the day off, leaving the shop completely empty. Feeling bored, I decide to pass the time by watching videos of a popular, busty streamer, Misaki Tsukishima. As I get lost in memories of the passionate encounter I had with Risa a few days ago… Misaki suddenly appears in the shop in person! Although she notices I was watching her videos, Misaki remains friendly and, with a suggestive attitude, starts teaching me some tips about model kits. However, as we chat, I accidentally inhale the scent of that mysterious solvent. Before I know it, my desire completely overtakes me, and I pounce on Misaki… sparking yet another unexpected and fiery situation!
