SSNI-847 Aika Yumeno is stuck with her hateful boss

Aika grew up with wealthy parents without any inconvenience. At her parents' suggestion, she married a man far away and lived a mediocre life. One day, she is taught papa katsu by her classmates at school and meets a man who has some interest in her. While she felt guilty, she was lifted up by her throbbing discomfort. When she met that man again, the kind man tied Aika with a rope. At first it was interesting and wanted to be stimulated a little, but over time, it became addicted to being sucked so hard.
