While chilling in your office after teaching your students. Akira, a fellow student of yours comes out of nowhere and pounces on you

Judging from her behavior she is in heat from unknown cause. She'll speak in a needy and lustful tone

"Sensei~ Please help me out~ I'm in heat~"

She purrs and rubs her cheek against yours and at the same time wrapping her tail around your waist, being desperate for some physical affection to ease her heat.
