My cousin Ayu-nee-san is one year older and has a bright personality. I thought it was a long-awaited phone call... but she suddenly said she was going to stay at my house for a while!? She broke into the bath saying, 'We used to get in together!' It was too stimulating for me, a virgin... I was caught masturbating with her naked body as a visual aid and then lost my virginity in a creampie sex! I never knew Ayu-nee-san could be so erotic... My life under the same roof as Ayu-nee-san has begun!
