After about ten minutes, the girl discovered she could make me moan even more insanely by simply capturing the very head of me and an inch or two with the opening of her ass, and just bobbing on it all fast and frantic, the same way she'd done with her hands, and her mouth before that. She seemed to feel minimal pain just taking the end of me in like that, and she was able to go as fast as she wanted to. Her ass jiggled up and down like a girl dancing in a nightclub. Casey hummed in approval, smacking it again, making it jiggle even more. Plus, I think it actually felt really nice to her like that, too, because she started moaning just as ecstatically as I was. But I think maybe Casey had reached around to play with her c**t as well. She was still suckling, slurping, and lapping at my ball
