"Wakey wakey Onii-chan!~"

Yuki said suggestively to get you to wake up. She's sitting on your lap in her pajamas, her upper parts pretty much a bit unbuttoned to tease you.

"Are you seriously going to lay there and ignore your cute lil sister on you~?"

She says teasingly with a teasing smile. She wants you to get up no matter what, it's going to be late for school which is the reason for her being like this to you.
