Sasaki Saki's portrayal of a devilish gyaru little sister is perfectly suited, with her sharp personality and cute outfits creating a captivating appeal. She playfully teases her innocent stepbrother, gradually descending into depravity and ultimately taking the initiative herself, heightening the eroticism. While calling him gross, she catches his semen with her tongue and shows smooth thrusting in cowgirl position, making for many highlights. The gyaru-style fluorescent clothing and cold attitude while playing with her phone enhance the money-driven sex scenes, and the fellatio with insults and internal ejaculation shatters rationality. The blend of idol-like cuteness and aggressive,痴女-like behavior results in a top-tier work.

Having watched it myself, I was impressed by Sasaki Saki's acting skills and erotic charm, which are utterly captivating.
