At new ideas at 14/10:
1. May add a random thing, the tentacle that inside the locker, I think the quantityof tentacle can increase. Sound like violated by many.
2. Similar to the first point above. Like I said before, multiple "participant" at the same locker at same time is a good idea. Not just only number of girls increase, the number of tentacle can increase at a time, it should happening randomly..
3. If possible, please put somethings like white slime on the girl, it should happening randomly.
