Unending Days of Creampie G*******gs Kana Yume - Yuai Kana

Kana Yume, a sister-in-law, is taking care of her younger brother Qian while his parents are abroad. She tries to discipline him for spending too much time on hobbies instead of studying, but her methods lead to a series of intense and intimate encounters involving creampie sex. As the story unfolds, Kana finds herself in a submissive role, apologizing and pleasing Qian and possibly others in a gangbang scenario, highlighting themes of creampie, submission, and potentially non-consensual sex.
