Due to my parents' remarriage at an older age, I suddenly gained a stepsister. As a recluse NEET, I naturally didn't get along with her and harbored resentment due to her condescending attitude. One day, while my parents were on a 2-night, 3-day trip, I drugged my stepsister and committed sexual assault. From that day until my parents returned, I completely confined and trained her. I disciplined her until she obeyed me.



















First of all, Ogura Yuna-chan's chubby gyaru look is seriously hot and cute. There are quite a few scenes of a blonde gyaru giving a really slobbery deep kiss, so if that's your thing, you won't regret buying it.
She was cursing and resisting at first, but then after waking up from the drug and being stripped naked, her resistance was so weak? I wanted her to keep cursing and fighting back while being assaulted. And then, she barely asks what happened afterwards. There's no emotional progression. I wanted to see her slowly corrupted and become submissive. I wish they'd included more everyday life details – eating, going to the bathroom – to show how her entire life changes.
