Two people who became siblings due to their parents' remarriage.
The younger sister (Oto) is overly infatuated with her older brother during puberty…
Their parents are unaware of the relationship between the two.
The sister receives cunnilingus from her brother while studying.
In return, she gives him a passionate blowjob.
She doesn't care about studying anymore. "Brother's dick is delicious."
While their parents are on vacation, the sister has her first sexual experience with her brother.
Affectionate sibling bath time.
"I'm happy that my first time was with my brother."The sister is like a manga character, her whole body is an erogenous zone, and she comes instantly from her brother's dick! She's such a weakling!
"Brother's dick fills Oto completely."
One day, the sister becomes jealous of a female classmate of her brother…
"Only Oto can make Brother feel good!"
Jealousy leads to forced vaginal penetration.
"You can't cum with anyone else's pussy!"
"Brother, not so deep (no～)!"
Then, the brother decides to attend a university in the countryside…
"My first love has become a long-distance relationship."
"Today, I'm going to fuck Oto senseless…"
Aaaahhh!! "Right there! Deeper!"
"Cum inside Oto's pussy~"If an stepsister is this cute, this horny, and has a weak pussy, of course it would turn out like this…
