After this, it would be something Rhys thought about. He had enjoyed being the one to be filled, but this was different. Both were good, both would be something he wanted another time. He'd work up to asking for it, or just... going for what he wanted. He'd done that before, he could do it again and probably better in the future knowing how both felt now.
If Joseph had pulled him from that hiding spot by any other means, Rhys might have given a little growl. Instead, he moaned into their kiss, the end of it a whine at the new sensation being presented. Every time they were together like this, he learned something new to like, something more about himself, and grew up that much more. He'd already become more assertive, even if it wasn't as much as he would have liked. He was trying.
He didn't know how long this would last, but he wanted to hold on just a bit longer. Probably not, though. Not with the way Joseph moved on him.
