My Summer with Onee-chan

That day, after that stream ended──
With the support of a mysterious sponsor, an older sister and a younger brother, now a university student, are freed from financial hardship.
They were finally supposed to be able to return to a "normal life."
But one day, an "intimacy gauge" suddenly appeared above their heads.
It was a sure sign that their relationship was no longer "normal."
They cook dinner side by side in the morning, and cuddle on the sofa watching movies in the evening.
Their fingertips touch in a spontaneous gesture.
Before they knew it, their time alone together was getting longer and longer.
The "fictional love" they acted out in front of the stream camera quietly and surely transforms into "true feelings" in their everyday lives away from the camera──
 
Until the day they cross that forbidden line. These brother and sister's tender, little by little, passionate "romance sim" life begins now.

As a hero, you must resist the temptations of monster girls and older women in this RPG to defeat the Demon King and bring peace to the world.
However, the monster girls use all sorts of sexual seductions to tempt the hero, and he ends up masturbating himself…
He indulges in the breasts of older women, his penis feeling great, and as a hero, he should be saving the world, but instead he is enveloped in the breasts of monsters, made to fawn and verbally abused, and ejaculates with a sense of both happiness and guilt.
You can enjoy seamless combat and eroticism, with monster girls using various methods to seduce you during battle, and if you lose, you’ll end up having sex on the spot.
