TST - I'm Obedient To My Scum-Big-Sister

Minase Haru was in love with the the school's idol Minase Kaoru, who also happened to be his older sister. However, in spite of that, he just couldn't be honest with himself and regretted it every day.

Due to a certain event he found out his sister was actually his brother, cross dressing.

"But I loved her even though she was my sister!"

After hearing that Kaoru accepts all of Haru's feelings........
And the two throw away the boundaries and flirt with each other endlessly.

Where exactly are the siblings going?
To go have sex in cosplay at school of course.

Haru gradually awakes to the joys of traps......

Kosuke and Sana, who met at university, exchanged their first experiences and eventually became friends with benefits.
Both disliked romance, so their relationship was purely for satisfying desires.
However, during sex, Sana—who was supposed to be expressionless and cool—began to show cuter and cuter reactions.
Kosuke fell for this changed version of Sana and started to truly like her.
Then, to split rent, Sana invited him to move into a new apartment together.
But his roommate turned out to be not only Sana, but also her busty older sister, Aira, who worked as a hostess.
Whenever Kosuke had sex with Sana, Aira would always intrude, pressing her pussy against him and making him lick it.
Unable to see Sana’s cute reactions anymore, Kosuke began to wonder why Aira was interfering.
There’s only ever one truth.
“—Could it be that her sister actually likes me…?”
No way… Or maybe yes!?
And so begins a harem romantic comedy where everyone ends up happy.

The protagonist who aims to be an adventurer arrives at the
"Adventurer Certification Test Center" with his peek-a-bangs childhood friend Momo.
To become an adventurer, defeat monsters and gain points through prostitution.

The protagonist has never had much faith, but he studied theology at a large church and became a priest. He holds a good outward appearance, but in reality, he's just a scumbag.

He was supposed to be assigned to a big city, where he could lead a glamorous life behind the scenes, but out of the blue, he was sent to a boring church in the countryside. He was in despair after reluctantly making his way to the countryside, but when he saw the beautiful sister who greeted him, he felt an instant surge of motivation and arousal.

The pure-hearted sister, who never doubts the goodness of people, is fooled by the protagonist, who pretends to think seriously about the countryside, and soon looks at him with admiration. Naturally, the protagonist sets his sights on the vulnerable and naive sister.

"I couldn't do this job without at least a few perks..."

"There's no place in this era for ninjas," is what the protagonist thinks despite having been raised in a ninja village. One day he is suddenly appointed as master of Kaede, a trainee ninja who has failed to progress in her training. Though he is normally put off by the closeness and affection she shows towards him, he is also starting to notice her rather developed figure.
Under the guise of ninja training, he is instead ready to teach her techniques of the sexual type. First up is a escape drill where he binds her with thick rope before the fun begins! This ninja training will involving a constant targeting of her feminine, vulnerable spots!
And after that...
