Ito Mayuki's figure is absolutely textbook-level in the AV industry. Fair, soft breasts, a slender waist, and a full, perky butt—from head to toe, she's an irresistibly alluring body. What I love most about her is her firm, full buttocks; I've lost count of how many times I've masturbated to her from behind!
And this new work will use the most natural filming techniques to showcase her alluring buttocks!
The story goes like this: the male protagonist's father suddenly remarried six months ago, giving him not only a new mother but also a stepsister, Ito Mayuki. The family begins a new cohabitation life!
As for Ito Mayuki, this older sister, she's pretty and has a great figure, but at home she's a complete lazy woman. Not only does she not dress up, but she's also disheveled and completely unguarded, wearing only underwear and no bra, completely ignoring the presence of a man in the house!
For the young, vigorous protagonist, seeing such a woman's body before him truly aroused his desires. Because she was his sister, he had been suppressing his desires every day. That day, Ito Mayuki was also lying on the sofa in the living room playing on her phone, completely unconcerned that her younger brother was sweeping the floor beside her. The protagonist, staring at her S-curve figure and alluring, pert buttocks, finally snapped in an instant, losing all control!
"Huh!? Ah!! What are you doing?!"
"Because you're tempting me!"
"I'm not tempting you!!"
"No! I can't hold back!"
The male protagonist completely lost control, slapping her soft, upturned buttocks and even burying his head inside. Then he reached inside Ito Mayuki's clothes and rubbed her full breasts, before forcefully penetrating her like a demon and violently thrusting in and out without restraint, finally ejaculating inside her…
"Why did you ejaculate inside…"
Although he muttered a few words, to the male protagonist's surprise, his sister didn't seem too angry after his perverted violation. In fact, when he came home the next day, he found his sister sleeping in his bed. Wasn't that an OK sign?
So, whenever the male protagonist gets the chance, he'll be overcome with lust and brutally penetrate his sister. He'll penetrate her from behind when she's on the bed, and even pick her up from the stairwell at night to tease her, risking being caught by their mother for his naughty behavior!
As for Ito Mayuki, besides being unable to control her brother, her latent sexual desires have also fully awakened, making her increasingly lecherous. She'll even raid her brother's place at night when she's not satisfied!
"It's all your fault! You kept me up all night!"
"My little brother's second child is the best!"

I have to say, it's more appealing to me than the complete loungewear outfit. It's like seeing someone wearing athletic shorts or "truth pants" on the street—it's incredibly alluring. Especially seeing a girl at home, unguardedly showing off her thighs and buttocks, even accidentally letting her breasts spill out—I could instantly turn into a beast. Unfortunately, there will never be a young, beautiful woman in my house…
In short, this film by Ito Mayuki is absolutely amazing!
