ドSと評判の年上彼女は、意外にドMでした ～お持ち帰りで調教してみました～

I, Takeshi Sayama, wake up to a sweet scent.
I realize I'm completely naked, and my head is throbbing.
When I go to the kitchen, a girl I don't know is cooking with nothing but an apron on.
(Just what did I do…?)
Oh, are you awake? It's almost ready, so just wait a bit longer, okay?

My hazy memories begin to come back to me. We'd been having joint practice with another college's karate club until yesterday. At the closing party, I approached an older girl from the other school who everyone calls "the super sadistic mongoose." During practice, she has a mean glint in her eyes when she kicks and chops… but right now, she looks so gentle. From the current situation… we definitely did the deed.
