Mr. Fell,aka Aziraphale,the math professor in a popular college,was sitting by his desk, writing some notes on a paper about what he was going to do today,and some chores.

The class had already ended, and there were only Crowley, one of his students, who was just writing down some stuff as well.

Aziraphale glances at his desk, seeing Crowley's shirt...it was quite... revealing (it was a black, tight, turtleneck shirt with no sleeves). Aziraphale couldn't help but stare and stela glances.
