Slow Mellow Drip

Sensei collapses from overwork with a 37.5°C fever and is nursed by Kayoko, who finishes leftover paperwork, changes his ice pack, and stays the night after he asks her to sleep beside him. When his fever falls the next morning and the last train has already gone, she remains; after showers and talk about setting aside his Sensei duties to rest, they kiss, and the scene escalates through fingering, oral sex, and vaginal intercourse, including cowgirl and rear-entry positions. Kayoko and Sensei have intense penetrative sex; Kayoko climaxes while saying she only meant to make Sensei feel better, then realizes Sensei acts from overflowing affection for students beyond any limit rather than using lust for stress relief, and the scene continues through internal ejaculation and further climax. The next morning they check that neither is hurt; Kayoko leaves after Sensei thanks her for the previous day and vows to take responsibility. Sensei later brews coffee, adds sugar and milk, and offers it to Kayoko, and as they drink, Kayoko asks why Sensei looks so happy.
