[orenjipiiru] Constanze's Laboratory (Little Witch Academia)

Akko's curiosity lands her strapped to a table in Constanze's workshop, where a humming mechanical sheath pumps away at her cock while the small, silent inventor scribbles 'Stress Test' observations from behind her clipboard. Once the machine has wrung a sample out of the panicked witch, Constanze reveals her own thick surprise and bends Akko over, driving deep as the sweaty girl begs her to go harder and tighter around her. Quiet gadgetry meets loud, breathless desperation as the petite tinkerer proves every one of her inventions works perfectly.
