Sumire-chan had her asshole developed by her boyfriend and is an 18-year-old student who can't refuse any requests. Despite being a third-year student in the table tennis club, her asshole has stretched to the point where it can accommodate a ping-pong ball. It's always raw when it goes in. Moreover, she enjoys it so much that she squirts from her ass. Sumire-chan, who has already sealed her fate with her asshole at this age, seems destined for a life of prostitution.
