When I woke up this morning, there was a female colleague in my room sleeping in her underwear! She's always so argumentative and prone to yelling, but she came over acting all cute... (Oguri Misao ROYD-250)

I woke up this morning to find my roommate, Oguri, sleeping in her underwear next door!? What's she doing here...? I was drunk at a drinking party and don't remember anything! But then Oguri woke up and told me, "We had sex yesterday!" That's shocking! Is she kidding?! Why does Oguri, who's usually so talkative, seem so happy? And now, with my penis being asked for again, I can't contain my excitement...
