[Creampie sex with my big-breasted sister, my first love!] When I was a child, Fumika-chan, who always used to take baths with me, came back to my hometown. Her marriage was called off and she is on leave from work... Despite all that hardship, Fumika-chan is still as kind to me as ever. One day when my mother was away, my reason was blown away by my sister's kindness and the sad expression she sometimes shows, and I pushed her down. My sister accepts me like that. It's been over 10 years since we last took a bath together, and Fumika-chan still spoils me as always. We have creampie sex over and over again...
