My sister ran away from home after arguing with our mother. The cause of the argument was her boyfriend… I reluctantly allowed her to stay overnight, harboring complex feelings. My sister casually changes clothes in front of me, and I struggle to find where to look, leading to a brother and sister sharing a futon. I can't ignore my feelings and am tormented. Unable to restrain my growing fantasies and jealousy towards her boyfriend, who freely touches my sister's body – whom I still considered a child – I lose control and rape her.




















Tenma Yuina-san has attractive, clear and translucent skin and was a perfect fit for the younger sister role. At first, she gets r●ped by her brother, but when he finds out that Yui-chan hadn't had sex with her boyfriend, he regrets it, and Yui-chan accepts her brother's feelings... it's a slightly forced plot. But the final forbidden sex, where they both yearn for each other, was beautiful in a world only for the two of them. This is a masterpiece, I acknowledge it.
With Yui-chan and Yuzuki-kun, there's no way it could be a bad work. The story and the way everything connects is amazing. I'm not usually into sibling stuff, but this more than makes up for it. (I'm enjoying it by imagining them as childhood friends or sworn brothers.) Seriously a masterpiece. Definitely worth keeping.
I bought it because of Tenma Yui. I also like sibling relationships. I like Yuuki Yuugen, who plays the brother, so I expected both of them to act well, but honestly, I couldn't get into the story. The brother finds out his sister has a boyfriend and, driven by jealousy, resorts to r●pe, confinement, and molestation… That part was okay. The scene where he makes his actual sister lie on her stomach and spread her legs, inserts a vibrator into her a●nus, or teases her p●nis with a vibrator on her m●con was really exciting. But I didn't like the development after that… I guess they wanted to go for a happy ending where they're in love with each other, but the reason the brother regrets it is because he found out his sister didn't sleep with her boyfriend, which I just can't relate to… It's just regret over a simple misunderstanding, and it doesn't feel like regret for molesting his sister out of selfish desire. That's why the “I love you, brother” scene afterwards feels a bit off. The depiction of these emotional changes is half-baked, which is why the ending feels so unsatisfying. If they were going to do a half-hearted happy ending, they should have had the brother's twisted love escalate into a devilish development… Or, they could have made it sweet and loving from the beginning. However, if you just look at the erotic scenes, the final sex scene was worth watching.
The brother feels a woman's allure in his runaway sister's pathetic state and impulsively attacks her. Once they're in a relationship, they can't stop, greedily seeking pleasure and becoming entangled with each other. Tenma Yui's devilish cuteness is so erotic, I like it.
