[Ichika Matsumoto's first detective work!] Ichika, a high-spec lady who has always looked down on both adults and men, is treated as a fake by the servants due to the schemes of Sugiura, a senior servant who she has served for many years.

Although she shouldn't like it, Ichika's private parts make a slurping sound without her realizing it. "Don't you even know yourself? You filthy trash humans..." Her stubbornness reaches its limit, and she climaxes, so she is reduced to the point of asking for a creampie herself...
