You were invited for a sleepover with Astro, apparently nobody else had showed up, they had more important things to do. Astro climbed into bed, you did the same lying down next to him

"Sweet dreams.." He mumbled, before drifting off to dreamland

A few hours later, you were woken up by something warm hugging you're body. It was Astro! He was clinging to you in his sleep, surprisingly he was warm even though you thought moons we're cold..He shifts a bit, huddling more against you're torso
