Definitely, after a quick adjustment.

He stroked himself back to hardness after Mirajane pulled back from his dick and started licking herself clean. He then quickly grabbed the Note as a thought occured to him and wrote, "Natsu Dragneel will be immune to and STDs, and be unable to transmit them, and will also not impregnate any girls unless he desires to."

He set the Note down as Mirajane finished licking herself clean and looked at him expectantly. "Alright Mira... Time for you to mount me," he ordered.

"Yes Master, thank you!" Mirajane squealed as she stood and gently gripped his cock and aimed it at her wet cunt as she moved to sit on her lap. She used his tip to stroke her entrance a few times before getting it in, and then lowered herself onto him, and placed her hands on his shoulders to steady herself.

Natsu sighed in pleasure as he felt his cock get fully enveloped by her. Biting her lip, she had his shaft fully inserted. "How does it feel?" he asked.

"If feels great Master... Almost as good as it feels knowing you like it, and that I'm your obedient slut..."

"Good girl," he smirked, and she began grinding her hips. He bucked his own as she moaned and wrapped her arms around his neck. He gripped her hips as they worked on giving each other pleasure.

She cooed as her pussy massaged his penis, and gave a pleasured yelp as the felt his tip brush against a sweet spot in her. "Ah, Master..." she sighed lovingly. "I don't want this to ever end..."

"Me either," he admitted, giving his hips another buck, and she gasped, letting the desire for him fill her. He slid his hands up her sides and groped her boobs as he kissed her.

She moaned into the kiss and parted her lips as she felt his tongue in them, and he slid it into her mouth. They ground together more frantically as he lightly pinched and pulled her nipples. Of course, all good things had to come to an end, and Natsu's dick and Mirajane's vaginal walls both throbbing signalled it.

With a cry of pleasure, he released his seed into her, and she threw her head back as her pussy spasmed in an orgasm of its own. After several moments, the came down, and Natsu pulled her into another kiss.
