This diary entry documents my summer vacation when I played with my perverted uncle. Aoi, a female high school student from Aomori, secretly desired to tease her uncle but was afraid that people would find out since they were local... But if she could just do it during her summer break while visiting him in Tokyo, then tormenting such a bad uncle wouldn't be wrong, right?! Her hidden sexual curiosity went wild under the pretense of putting an end to his perversions...! She experiences anal penetration, rimming, double-headed dildo, strap-on, anal plug insertion sex, and gets fucked by both her uncle's cock and the dildos until she squirts multiple times in a W-orgasm! Finally, she shares this unforgettable memory filled with training sessions on her uncle's cocks and a strap-on orgy.
