A plain aunt

Makoto is taking care of Sayaka's aunt in the house of the suburbs of Tokyo in order to attend a prep school. My aunt was very plain and I sniffed rice crackers and wandered around in lame underwear every day. Makoto is disillusioned with the vivid appearance of her real aunt, far from "a sweet life with her beautiful aunt...", but one day, when she closely looks at her sleeping aunt, she looks surprisingly beautiful... Then Makoto became curious about her aunt, and secretly looked into the couple's bedroom and saw her lewd aunt, which was something that she would normally never imagine...
