HHKL-085 - 「お兄ちゃん、なにしてるの？」普段は子供っぽい格好で色気のないうぶな妹がまさかのTバック！？そのあまりにも魅力的なお尻に理性は崩壊！ 桜井千春

I bought this because I liked the doggy style photos. Lol. The girl was cute, so it was good.

Doggy style, back-entry, and reverse cowgirl—this is a work for butt lovers. There is no missionary position. The gameplay might feel a bit lacking, but the actress was cute and had a youthful style, which I liked. Looking forward to her next work.

Personally, I wanted to see her looking reluctant when her brother suddenly attacks her.
