We went on a hot spring trip without telling Riri's mom and dad. Riri took a record of the trip. Riri is a modern girl, so she teaches her uncle all kinds of things. She also loves naughty things, so she touches his body all the time and presses her small breasts against his arm, even tempting him. Every time Riri and his uncle get excited and erect, Riri serves his uncle's penis gently, and sometimes meanly. She gave him a blowjob in the car before we arrived at the hot spring inn, and after we arrived, we washed each other in the bath, touched each other, and ejaculated into her immature breasts and pussy many times. In the futon, Riri showed me her special "toy", and her provocative appearance made me more excited than usual and made me cum more violently... Riri is my uncle's precious girl. I made some great memories with Riri. *All performers in this work are adults over the age of 19.
