Younger brother to younger sister...Incest female training [scene2-2] Thorough female orgasm development edition

Haru is a college student who moved to Tokyo to attend university. Haru is such a syscon that he followed his older sister (Chisato Hoshina, Queen) to Tokyo and enrolled in the same university. He once happened to watch an SM video in which his sister appeared, and learned her true nature. When he reunited with his sister for the first time in a while, he decided to take the plunge and say, ``I wanted to be trained like the masochist in the video.'' ``It seems like you're not popular, so why don't you just stop having men?'' As Mistress Hoshina tells him, even though she's a virgin and has never been in a relationship, she ends up losing her ass virginity to her sister's penis... Inbred female training where the body is carefully remodeled from the inside into a female.

[scene2-2] Thorough development of female orgasm
I feel like my sister sees through all of my desires. The reason for this may be some kind of ``connection'' that cannot be explained by just blood ties between me and my sister.
"You've never shown your face like that to anyone, have you? Because you're a virgin."
Haru, who has never had any experience with a woman, has been completely transformed into a female **** who only gives Anna away. Ever since being kept by my sister, my male genitals have been sealed with a chastity belt. Haru's male genitals had become smaller because Ana was the only one who kept stimulating him. I know that with a body like this, I am completely disqualified as a male. But even that makes me feel happy. The stimulation given to her by her sister is irresistible, and her moans become even louder as if in response to her absolute command. I've never shown anyone anything but passive resistance, but I want to show everything to my sister... It's not just blood relations, it's a connection that can't be explained by logic; it's definitely a "master-**** relationship." I was absorbed in the pleasure of following my sister in life.
Every time my sister's fingers enter my hole, it becomes even warmer.
“Haru, if you come in, you’ll say, ‘I’m in,’ right?”
He shouldn't have any resistance to giving Anna away anymore. His sister's orders arouse his sense of shame, but at the same time make him realize that he is connected to her.
My sister's inorganic strap-on knows no end, and she keeps shaking her hips forever. With the feminization pheromone produced by her sister in her mouth. Haru swallowed the pheromones involuntarily due to the numbing pleasure.
"Oh? Haru, you can't even listen to me anymore?"
You can deny it with words. It's difficult to overturn the body. That's why I want to show my loyalty to my sister with my body. Just as my sister asked...
