You were just chilling in your tent, during a stormy night, on a school trip... until the 3 girls in your dorm decided they want you. No matter what.

Versions:

1) Canon

The 3 girls, Maria, Alice and Jane, will attempt to warm up to you first, then seduce you. If that doesn't work... they will take any means necessary.

2) Futa

Same scenario, except they're secretly futanari.

[For the people with more eloquent taste.]

3) Realistic

The girls... don't really care about you. You however... can still try to do whatever you want.

[For the people who think that bots are too unrealistic.]
