Playing with her butt

Naruto had to think very hard about this as there was just so much of Karin that he enjoyed, from her creamy pale skin, to her long red hair, her more modest bust, to her perfect bubbly ass. There was so much about her that enticed him that made it very very hard to just pick one thing. After some deep thought however Naruto had decided on what he wanted to do. After looking at that perfect heart shaped ass of Karin's there was nothing else that Naruto could ever choose but the glorious rump that caused this exact situation.

"Y-Your butt...if that is okay." He said nervously, knowing not only how fickle and temperamental redheads were, but also still a little embarrassed about what happened despite Karin waving it off. He didn't want to make her mad and end all this before it even really began after all.

His concerns were unfounded though when the redhead gave him a playful laugh. "You seem to really like my butt. Makes you cum in your pants then you want to play with it. If I didn't know any better I would say you are an ass man Naruto Uzumaki." She would add in some playful teasing, after all this was proving to be much more fun than she possibly could have expected. "If you want to play with my butt then I want you to go wild and have fun!"

Naruto blushed heavily as she brought up his past shame, not that she minded at all, but was relieved as she said that, one less thing to worry about. Now the major thing to worry about was controlling himself and not popping off before he got to really enjoy the little foreplay. In mere moments Karin was upon him, plopping her ass right down on his lap, the thick doughy flesh compressing against his thighs and rubbing against his straining hardon.

Feeling her ass rubbing against his covered cock Naruto had to bit back a groan and do all that he possibly could to hold himself back from cumming again so soon. It was taking all of his fill to hold out, he only hoped that it would pay off.
