9.2.d It will be better to have a study group

Upon arriving at the magic university, you immediately set out to meet people. You befriend a group of girls. Together, you attend classes, share meals, and even spend time researching in the library.

You develop an interest in summoning magic and share this with your new friends. They warn you that it's an extremely difficult art to master, especially when summoning living beings, but promise to help you study it.

You begin by summoning small inanimate objects: coins, inkwells, feathers, etc.
The next step is summoning tiny living creatures. First, you summon insects and simple lifeforms. Then, you progress to birds and even small mammals like mice.

Everything goes smoothly, so you all feel ready for the next challenge: summoning beings from other planes. You prepare the ritual circle and begin calling forth entities from beyond.

Small leech-like creatures writhe within the circle, appearing harmless at first.

Encouraged, you and your friends amplify the summoning to call something greater.
What you don't realize is that this "greater" entity is intelligent, and has been trying to summon you ever since you opened a connection between planes. The circle expands violently, and an uncontrollable **** drags you all into an unknown realm.

There, an aberration awaits, its tentacles ready to defile you. The horror begins dissolving your clothes, its many appendages penetrating your friends' every orifice.

You desperately try to reverse the summoning, but it's futile.
The creature finally reaches you too. Its tentacles violate your ass, pussy, and mouth, pumping a corrosive fluid that dissolves you all into nothing more than this aberration's meal.

BAD ENDING: Kidnapped to another dimension with friends
