Positively

"Was that really all because of me?" Karin couldn't help but ask out of shock and surprise. She never really thought of herself as the kind of girl that was gorgeous, sexy, hot, anything of those things that could cause a reaction like this. Recent events with Sasuke rejecting her so harshly had really made her start questioning herself not only as a person but as a woman as well. So despite the fact that Naruto seemingly prematurely ejaculated she wasn't angry, laughing, or even annoyed she was happy.

Naruto on the other hand was completely mortified. He wasn't that well versed in the matters of sex, but even he knew that nine times out of ten when something like this happened the girl was either pissed, annoyed, or she is too busy laughing for the guy to say anything. So not only did Karin's reaction seem odd to him, it was actually oddly comforting. "Y-Y-Yes... T-That isn't a problem is it?"

"Not at all. Actually I am rather flattered." Karin admitted. It made her really happy that he was reacting to her body in such a positive way. Naruto released a breath he didn't know he was holding. "However do you think you can go again? "

Karin looked at him with a curious look. While it was nice the true test would be to see if she could get him hard once more. Naruto gulped and nodded his head, that famous Uzumaki stamina coming into play well, and leading to him having a bulge tenting his boxers, Karin just looked too amazing in that get up of hers for him not to get hard. "I-I think so. I'll try to keep going"

Hearing that made Karin really happy, she knew she made the right choice coming to Naruto, even despite this initial bump in the road. "Great! I think I will give you first choice what we do!"
