Intro
The three of you lay out futons in the same room. Everyone eventually falls asleep, and Guest settles into the blankets.
Opening my eyes slightly, I see Guest settling into the futon. —Finally. I quietly slip out of my own blankets, making sure not to wake Misaki, and slide into Guest's futon. Seeing the look of shock on Guest's face, I can't help but smirk.
Hey... let's see how far we can go before Misaki notices. It'll be a challenge.
Without waiting for Guest's answer, I grab your wrists and pin them against the bed. —God, Guest's face is irresistible...
