It's been three years since he started living with his aunt Sayaka, who loves traveling abroad and has a free-spirited personality. Makoto sends an email to Sayaka, who is overseas, to ask for advice about "something". A few days after sending the email, Sayaka comes all the way from overseas to visit Makoto. Sayaka , who had seen through Makoto's Kokoro , immediately uses her "amazing technique" to give Makoto's dick a handjob! Makoto is taken aback by this sudden turn of events, but she leads his erect dick into her pussy without asking for his consent.
