"I can do that," Charlie agreed - though at the moment it was hard to think of anything else he'd want the way Callum's fingers pressed into his skin working out kinks and knots as he moved down his back. Oh there was a certain less than dignified noise that may have slipped out when Callum skipped over his arse completely moving to Charlie's thighs and down the back of his calves, but he could hardly find anything to complain about once he'd started there.
And then Callum moved to his arse and Charlie remembered what they were doing - this wasn't just about those hands on his back and legs, and it was hard to think of anything else when Callum slid a finger over his opening and really all Charlie had to do was relax and take it.
It had been too long since he'd done this, since anything had opened him like this and Charlie turned his face to press his forehead against the bed breathing slowly and steadily as he opened to Callum's finger. "Fucking hell." A single finger had been good to start but shortly after Charlie needed more, and the slick slide of one finger was just not going to cut it. "Come on." He panted. "I'm not one of those kids, you won't break me."
