I Want to Escape, But...!! The Room Where My Hips Won't Stop -Succubus Edition-

As the protagonist was operating his PC as usual,
a rather suspicious advertisement suddenly appeared, filling the entire screen.
[Otherworld Invitation Program]
--Free Campaign for a Limited Time Only!
"It's probably a scam or some kind of joke."
Thinking this, he casually clicked "Agree"—and at that moment, his vision went black.
When he next woke up, he was in a place that looked like a video game world.
Standing before him were an angel and a demon, almost completely naked.
Confused, he pleaded, "I want to go back to my original world," to which the two casually replied:
Angel: "Travel between worlds requires the currency of this world."
Demon: "That's why we made the one-way trip free as part of the campaign."
Apparently, the only way to return was to earn money in this world.
And so, the protagonist begins to complete requests from the angel and demon,
aiming to return to his original world.
However, as he progresses through the requests,
the erotic pranks and sweet temptations increase...

You wake up in a white room alongside your two best friends in underwear. You don't remember how you got there, but you soon discover that a former friend of yours has prepared a series of sexual games... and you are the main characters.
She has locked you inside her private complex, and you'll have to pass through various rooms designed exclusively so she can get excited watching and directing those games. To open each door, you'll have to complete sexual challenges that will test your friendship, your hidden desires, and your will to escape.
Each room is more intense than the last, and if you refuse, she won't hesitate to punish you... through sex.
Eventually you'll discover fragments of Amber's past. Why would a rich, beautiful, powerful woman build this place? And why do you have to be the ones trapped there with her?

Collect the magic fragments that have fallen, without getting caught by the succubus! The magic fragments are generated randomly, just like in dungeons, so they will appear in various places! (Some of them have fixed appearance locations.)

A girl suddenly appears in my dream, revealing herself to be a succubus and proposing a game.
If I win, I'll wake up from the dream.
If I lose, I'll be her sex slave for life, having my semen extracted until I die.
The game is tag.
If I'm caught, I'm tempted and ejaculate, and I lose.
However, the girl says it's a handicap and doesn't touch my penis at all.
She says she'll play with my penis if I ask, but that would be tantamount to admitting defeat and declaring my willingness to become her sex slave.
Can I resist the temptation of this bratty succubus and my own desires?!

Touya Utakata, advisor to the Occult Research Club, heads to the old school building alone at night to meet up with students who have gone ahead.
However, the moment she steps inside, the door slams shut, cutting off her escape route.
What awaits Ms. Touya in the darkness is not her students, but countless eerie tentacles covering the floor and walls…
What will become of Ms. Touya…?
