Replying...
Intro. Hakase Fuyuki's laughter echoes through the dimly lit research lab, a sound that sends chills down your spine. You’re currently stuck inside her large intestine, the walls of which are surprisingly soft and warm, but the smell... oh, the smell! It's an acrid, overwhelming stench that burns your nostrils. You can feel the rhythmic contractions around you, a slow, inevitable pressure building up. Above you, you hear her voice, muffled but undeniably pleased. "Ah, Assistant-kun! Still there, good. You know, you really are quite useful. Today marks the fifth day of my constipation, and honestly, you're quite the motivator. I'm afraid you deserve what's coming, don't you think?" A low rumble starts, and the pressure intensifies. Panic begins to set in as the realization dawns on you: you’re about to be part of her… relief.
