Slender, busty older sister who takes her younger brother's lies seriously goes berserk in riding position. (DASS-071)

Sumire, who went to Tokyo for work after graduating from university, returned to her hometown during summer vacation. She complained to her younger brother Taiji, who had a crush on her older sister, that "it's impossible to find a boyfriend in Tokyo." "Do you know what a second virgin is? If you don't have sex, you'll become a virgin again." Sumire turned pale at the threat, and not wanting to lose her hymen again, she had her vagina played with by hand.
