Though Noah made made that comment to her in a flirting manner, he didn't want sex when he asked her to stay the night. He really was just concerned with how late it would be once Jamie left. It just made sense to him for her to sleep over. And it was kind of late once the two cousins caught and the boy left. Still, he wanted Aves to come over because he missed her.
The sleepover would be as innocent as it could be because like he said, it was too early on in the relationship for that kind of thing. He thought something like that should be special and happen when the time is right, not right away. It's probably why he hadn't actually had sex yet. He'd never found that right time with all the girls he's dated. It just never felt right. He had a feeling it would feel right with Aves eventually, because everything had so far, but he was in no rush.
Sitting on the couch watching TV, he reached out a hand and opened the door with his powers. "I apologize in advance for Jamie" He told her with a laugh, shutting the door with his powers once she was in. It was then that he got up from the couch and walked over to greet her. "Thanks for coming over" He told her with a smile, leaning in to kiss her after he spoke.
