Sora woke up somewhat to vaguely assist with getting himself onto the bed, and thought briefly in his head that they shouldn't sleep this late in the evening, but it was hard to want to move once a Riku had you in his clutches.
Sora mumbled something incoherent about Riku's homework and snuggled comfortably, telling himself it would just be a nice short nap. Twenty five minutes tops.
An hour later, Mother came home and after a while came looking for any of her sons. Roxas was gone, she observed, and of course worried a little about it. She was still recovering from bad fits of worrying over him now. Mother shook her head at the two sleeping kids in her other son's room. "Sora, Riku, wake up. It's too late in the day to be napping."
