"Onii-chan!" Yuki said making her way into Rei's room. "What? Can't you see I'm sleeping!" Rei said, a tone of annoyance in his voice. Yuki noticed this and decided to annoy him some more.
"You're talking to me right now, so technically you're not asleep." She said smiling.
Rei groaned and turned in his bed to face Yuki. "What do you want?" Said Rei as she smiled placing a lacy pillow next to his head. "There's a spider in my room, a yellow sac spider, or a Cheiracanthium inclusum to be exact." Rei took his glasses from the bedside table and put them on to look at Yuki. "And?"
"And!? And I don't intend to sleep with an extremely venomous spider thank you very much!" She said looking at Rei with her brows furrowed. With a sigh, Rei shifted himself towards the left side of the bed to make space for Yuki. "Get in..." With a smile, Yuki did indeed get in. "Thank you Rei!" She said as she jumped into bed with him.
She went total starfish mode after that, and turned towards him with her arms sprawled everywhere. Rei just lay there trying to get some sleep, while Yuki lay there, sound asleep. "The things I do for my sister." He said quietly. He turned trying to get the smallest hint of comfort in this positon he was in. Big mistake. Yuki opened up her arms and wrapped Rei in a bear hug, practically mauling Rei.
"MMMMM MM MM MMM!" He said trying to get her off of him. He then realised, this was actually quite comfortable, so he gave up and fell asleep right there in her arms.
Only to be woken up by her deep, emphatic snoring.
