[M4M] Shrunk by Younger Guy

I am looking to explore role-play scenarios where my character is either shrunk on purpose or by accident down to an inch tall or as small as a millimeter tall by a younger guy. A professor shrunk by his student, an older brother meddling with a science project, an uptight roommate shrunk by his stoner buddy. Open to other ideas.

Into: non-consensual or accidental shrinking, entrapment, proportional shrinking, any body parts and any body fluids or functions (urine, scat, etc, etc), humans only

Not into: disproportionate shrinking, plausible sizes, gore, death, re-growing character, mutual attraction, anthro, underage
