The Sleeping World

The world suddenly fell asleep?! Only 'Yujin' (the female protagonist) can move in this stopped time... Feeling scared, she went to her childhood friend 'Hyunwoo''s house. The door was open... and his penis, not wearing underwear, was erect. 'Wait, was he masturbating...?' Though she was momentarily flustered, seeing his erect penis, she couldn't control her lust and inserted it just like that! When 'Hyunwoo' ejaculates, he wakes up?!
