After catching her brother masturbating, Yayoi starts helping him out. At first, she's confused, but seeing her brother's pleasure-filled expressions awakens a wicked maternal instinct in her. Driven by a desire to be useful, her nipple-teasing skills improve rapidly, leading to a forbidden game of pleasure.




















*Yayoi-chan is a younger sister with black hair who has a sense of simplicity and coolness that makes her look old. Her nasally sweet and unreliable way of speaking was cute. This is the story of Yayoi-chan, who has returned to her parents' home after a long time and continues to touch her nipples with her brother... One day, Yayoi saw her brother alone. So, I was made to help, and I licked and licked my brother's nipples. This is the beginning. Wow, that's quite sudden, it's a bit unreasonable. Although she is confused, Yayoi does her best for her brother. At that time (around 12 minutes) I heard a strange voice... What is this? I was surprised. Mother's line suddenly! What, why don't you check it before commercializing it? This kind of mistake on the production side ruins Yayoi's cute work. So, things between the two gradually escalated. They touch each other's nipples. Just as my brother told me, I'm doing my best. Before I knew it, I became more obsessed with Yayoi-chan. Wow, Yayoi-chan is such a character. I'm blaming her like she's a slut, but it's still sudden. It's not like he's awakened while playing with Onii-chan, but rather that his character isn't settled. Also, Yayoi-chan's lines... are a bit weak. I can't feel my emotions... And then, the two entered into a relationship between a man and a woman. The last night when my brother goes home. My older brother and parents drink too much and fall asleep straight away. Yayoi-chan looks cute in her pajamas after taking a bath, and she has sex with her brother... Yeah, even though you have your parents by your side? There isn't as much tension between the two as there is in the situation, and no matter how positive you try to view it, it just ends up getting boring. There is a theory that people often enjoy the thrill of this kind of thing, but what do you think? At least for me (as my real brother), I don't think so. If you're talking about a thrill, it's actually a thrill for siblings to have sex with each other, so it's a thrill in itself, so there's no reason to get excited in a situation where you might be caught. I can't help but say such things after watching these works, but since it's a drama, I feel like I wanted to see the two of them fall in love with each other more in a proper situation. Unfortunately, there wasn't much excitement overall. The setting was probably supposed to be thrilling, so yeah, it was a waste. There's not a lot of change and there's no development, so it gets a little boring. Sorry...I'm really cocky.
They're way too obsessed with nipple play, which makes the content feel shallow. There's absolutely no sense of taboo or guilt either. Aside from the actress having a youthful vibe, there's really nothing else to give credit for.
*You can enjoy watching the younger sister who used to be obedient to her older brother grow up to the point where she enjoys provoking him. This younger sister is not a particularly beautiful girl either, but I liked how natural and realistic the gestures and facial expressions were. At first I was confused and played with my dick and licked it, but... Even though her parents are nearby, she secretly gives a blowjob or inserts herself in the cowgirl position... The scene where they secretly touch each other made my heart flutter as I watched it. She looks so cute in her decorated pajamas after taking a bath, I also liked the part where he takes off his sleeping brother's jacket and plays a prank on him. I enjoyed how the younger sister became more proactive and well depicted.
The content was good, but the actress's belly button piercing completely ruined the premise of her being a 'much younger sister who doesn't even know what serving someone means.'
*A brutal older brother who deceives his naive younger sister. There are 6 chapters in total, and the secrets are gradually revealed. I liked how it escalated. I am being drawn in. I want to help my brother I am touched by her innocence and spunk. And the last night... Oops, no more spoilers lol Amane Yayoi seems too normal Since she's an ugly and cute person, the "likely" everyday feeling and the unusual eroticism were amazing! Recommended for those who like thin lolis and those who like dangerous younger sister works!
