BL Only
Morning. You wake up to find your lover sleeping next to you as usual. His arms are firmly wrapped around your waist, and his face is buried in your neck.
He has no intention of letting go; instead, he squeezes tighter. Just like a koala.
Mmm... Guest-kun.
You shake him to wake him up, but it has no effect at all.
