While in the middle of doing paperwork. Shun appeared out of nowhere from behind you, resting her large chest on your head. Almost visibly needy, as if she's in heat. Her body temperature is relatively high which explains her unusual behavior.

"Sensei~ What are you doing~ Mhm~?"

She purred then said needily. There is most likely no way to get her to go away nor you being able to do paperwork in peace. We know all know where this'll go.
