[Ne. (Shiromitsu Daiya)] Tenshi to Akuma wa Kamihitoe

Bratty crossdressing students Anju and Dai corner their bald teacher to 'thank' him for letting them dress however they want, and their gratitude means putting him to work. Sweet-voiced Anju coos for a condom before taking him deep, breathlessly moaning that it's swelling like a balloon in his belly, while sharp-tongued Dai keeps a shinai raised to keep the sensei in line and barks insults like 'animal' and 'virgin' between thrusts. Caught between the angel's hiccuping cries and the demon's sadistic grin, the overwhelmed teacher is wrung completely dry by his own students.
