彼女のお姉さんと中出しセックスに明け暮れた日々。 日下部加奈 (2021)
A few years ago, her parents passed away, and she and her younger sister have been supporting each other ever since. To protect her still-young sister, she quit university and started working. It was busy, but it was fun. They cried a lot and laughed a lot. Then her sister got a boyfriend—an older, reliable man. She felt a little envious. As if seeing right through her heart, he stole her lips and pushed her down.
