Have her blow him.

"Alright Tenten," he said, taking his hands off her body, making her whine a little. "Kneel down, and take out my cock and start sucking."

She nodded, and sank to her knees before undoing his pants, freeing his erection, and engulfed his cock in her mouth without hesitation. She sleepily moaned around it as she slowly bobbed her head on it.

Naruto smiled down on her, putting a hand on her head as he pumped his hips into her mouth a little. He could feel her tongue running along his dick in her mouth, and that felt really good.

"Tenten... Lightly spank yourself while you are blowing me," he ordered her next, and without hesitation, she reached behind herself and slapped her own butt softly, but enough to sting, making her moan around his shaft as she kept going, continuing to spank both of her own ass cheeks.

She pulled off briefly to lick his length and ball sack, moaning with every slap she gave herself, highly aroused before returning to blowing him.

It wasn't long before he hit his limit at the sight and stimulation, and pulled out, jacking himself off. "I'm cumming Tenten, open your mouth and stick out your tongue."

She obliged, her eyes now partially open in a blank stare. He grunted, and released his seed over her face, getting most of it on her tongue, but the rest hit her face and boobs. He panted a moment as she remained in position, no longer spanking herself as she wasn't blowing him anymore.

"Lick yourself clean," he ordered, and she started to do so, meanwhile, he considered what to do next.
