[Orenjiya (Orenji)] Constanze's Laboratory (Little Witch Academia) [Uncensored]

Constanze has Akko right where she wants her—strapped into the machinery of her cluttered workshop, legs spread and helpless as mechanical contraptions work her over while the silent inventor watches from behind her tablet. What starts as bewildered protest ("W-what is this!? It won't stop!") melts into gasping surrender as Constanze's tongue finds places Akko definitely didn't expect, driving her toward a climax she can't hold back. By the time she's screaming Constanze's name, the mute little engineer has proven that her laboratory experiments don't always need words to get results.
