俺の妹は清純ビッチ ～親には秘密のハメハメ性活～

The older brother of [url=https://vndb.org/c74120]Ena[/url] and a virgin who get conscious of his little sister. He really hates when she brings men in her room because he can heard her moaning behind the thin wall who separates there rooms.

Even if he isn't a huge siscon, he often masturbates by fantasizing about Ena or while she is with a boy. He is envious of her success. He thinks that Ena is the complete opposite of the "ideal sister type" you can see in anime or manga even if he thinks she's cute.

He hates that his sister is a bitch, and they do not get along well because of that. He often calls her "bitch" in his mind.

[spoiler]He is completely inexperienced and often thinks he is a "bad range" partner for his sister compared to all of her former partners, although she tells him they have an "incredible compatibility".

Seems to have a huge Baby Complex because, to "win" his sister, he wants to fertilize her at all costs.[/spoiler]

Hoshizuki Souma 星月 奏馬

Ena is [url=https://vndb.org/c76033]Souma[/url]'s younger sister, unlike him, she is very popular with the opposite sex and often brings men to her room. Her parents don't suspect her true nature and think she has a boyfriend but she makes them believe that "he is just a friend, nothing more". She already had, at least, 3 "boyfriends" (= sex friends).

She doesn't seem to care who can be her partner (before having sex with her brother). 

When her brother interrupted her, she decided to take revenge by raping him. She immediately found their compatibility "excellent", telling him immediately that it was the first time she felt so good. Since, she becomes aware of her brother as a member of the opposite sex and tries to seduce him sexually.

[spoiler]Later, she becomes aware of her deep feelings and finally start to seduce him seriously so that he can become her boyfriend and she no longer seeks to see other boys. But because Souma is very dishonest with his feelings, she decides to lie to her brother in order to make him explode of rage while going out with her [url=https://vndb.org/c76034]former Sex Friend[/url] on the day of the festival in order to force her brother to confess his true feelings.

She is very clever and knows her brother very well, she knows that only jealousy will make him say his true feelings and that to have more control over him, to let him fertilize her and to promise him a child.[/spoiler]

"Not again today..."

The squeals of my younger sister, Ena, echo from the next room.
Both our parents are at work, and Ena takes advantage of the situation by constantly bringing her boyfriend over and having sex with him in broad daylight.

Hearing this every day is enough to make my frustration reach its peak!
Today, I couldn't take it anymore, so I barged into her room.

Her boyfriend hastily retreated, perhaps not realizing that her family was at home.
Ena sent her boyfriend off without even trying to hide her naked body.

"Oh no, I haven't come yet... That's right♪"

Ena grinned.
"Since you interrupted, I'll have you fill in for me."
"Huh?!"
And before I could even process what she'd just said, I was pushed down...

"Wow, this is amazing. I've never seen anything like this♪ Oh, I don't have a condom... 
Hmm, well, I guess it'll be fine as long as you don't cum inside me.
Also, I was curious about raw sex♪ So, I'll use this, Big Bro♪"
