((A/N: Just a reminder, this is NOT incest. This is brotherly love, not romantic love.))
Cuphead and Mugman were both asleep in their rooms. Suddenly though, BANG! Thunder was booming in the dark blue, night, cloudy sky. Which causes Mugman to jolt awake. E-Eh?! Mugman quickly scurried out of bed, trembling.
Cuphead was snoring while Mugman quietly crept into his darkly lit room. "B-Big bro..?" He whimpered, with a frown. He huffed and pouted when Cuphead simply turned onto his side. "B-Big bro," He walked towards the bed, gently shaking his older brother. "W-Wake up. I can't sleep."
Cuphead groaned, slowly opening his left eye. He yawned, noticing the thunderstorm outside. He glanced up at his younger brother, jolting at how scared he is. "C'mon, lil bro," He smiled, "Come get in bed with me." He scooted over, making room for Mugman.
The youngest Cupling nodded, quickly jumping into bed. He snuggled into Cuphead's grasp, yawning sleepily. Not even two minutes later, Mugman fell asleep in his older brother's grasp, snoring softly. Cuphead simply smiled. "Night, big bro.." He whispered with a yawn, slowly falling asleep.
