Your Naughty Little Sister gets Worried and Scolds you as she Nurses You Back to Health ~Nursing Journal: Day X~

You and your little sister Chie (CV: Suzu Sazanami) were like cats and dogs,
always bickering and at each other's throats.
That was until the two of you ended up having sex together!
From there on out, curiosity and lust run wild... and your days are filled with sex, sex, and more sex!

Then one day, you catch a cold.
The worst of your fever passed after several days of rest, but your worried little sister is set on thoroughly nursing you to make sure you recover well.

It all starts when you pop a boner while she wipes your body with a towel.
She jacks you off to calm down your dick, and then the sexy treatment escalates...
