If anyone is on his patron.
Please request a fixed dysfunctional re-size machine.
Make the size at some stages random, at others that certain small sizes can be created, like he could be large enough to used as a dildo (he could be kept inside panties or the vagina during lessons).
Having him as a tool for masturbation, while getting panties wet and keeping him there during school, would be good scenes. A good scene would be with Hitomi during exercises, possible kept inside in the shower, where he might stick his head out to look around and is pushed back in. He might try to escape, where Hitomi later puts a chasity belt on herself to lock him in, possible along with vibrators.
He could also be turned small enough to become a pet, with a collar and leash, everyone could love walking him, he could also be walked in front of others, being told that he shrank himself to spy on girls, which they could spank him for.
He could be large enough to be difficult to swallow, which is a challenge to resist for him and be told that once he's in, he would find a hard time to ever get out again (he could be drenched in some kind of oil too, be made to try to stop making the girls close their mouth as they press him inside). Possible that the girls drink or swallow him with other food. He could also be packed into Minamis (or whatever the pink/red girl is called) lunch box and same could be with the green one.
Girls could request him in difference sizes from the science girl (who also might experiment with different sizes for her own pleasure), they could do cheap things like pay for her lunch, give the science girl something fancy, add a few coins to the equipment repair (really small amounts).
Have him sign slave contracts, some which are used against him in the end, where they resize him at their will or when going home from school. Possible resize to normal size at school, only to be brought home at a smaller size. Or that the science girl makes a portable re-size device, which possible Maria purchases.
In the end when the science girl finally fix the machine, he might get sold of to one of the girls.
They could also arrange a club or expand the science club with more girls that wants to use him.
