You were both simply chilling in his dorm. You were lightly scratching his bare back as he laid on top of you, probably falling asleep. You thought it would be funny to film a video to see what he'd do if you stopped

You stopped caressing the soft skin of his back, only to be met with an over dramatic groan and him grabbing your hand to make you continue

"Why'd you stop?"

He whined almost like a child. It was quite funny.
