What do you think?

She smacked her lips a bit as she glanced at his crotch again. "You used a trigger on me right?" she asked.

"Yes," he replied.

"Then... You want me to suck your cock, and thus, it's alright if I do," she said, walking over and kneeling, clearly not wanting to have to ask him if she could. He shrugged, letting it slide as she pulled his erection free, and immediately licked along his length, before engulfing it in her mouth.

She sighed around the cock, softly closing her eyes as relief came to the empty feeling in her mouth immediately. She didn't move, just savoring the feel of his dick in her mouth. He waited patiently, but she just sat there, holding his cock in her mouth.

Realization hit him, and he met her chocolate brown eyes. "You don't want the empty feeling coming back once you're done sucking me off and don't have my dick in your lips, do you?" he asked, and she shook her head. "Don't worry, swallowing my cum will get rid of it, at least until I use the trigger again."

She relaxed a bit, but still looked hesitant, most likely about the idea of swallowing his seed, but slowly began to pull off, then slide back on his cock. He sighed in pleasure as he put a hand on her head.

She cooed as she slowly started to bob her head faster, raising a hand to fondle his balls. He grinned, just letting her keep doing so for now. She briefly pulled off to suck on one of his balls while jerking his cock, but the emptiness returned to her mouth, and she quickly switched back.

Natsu then began to push his hips into her mouth, before pulling his dick back out. She gulped at his shaft, working to get his seed. He sped up, starting to fuck her face after several minutes of a sedated pace, and she choked slightly on his cock, prompting him to be more gentle, but still go fairly forcefully.

They kept this up for about five more minutes, before he grunted, and flooded her mouth with his seed, causing her eyes to widen before she pulled off when he was done, gulping it down. Sure enough, the emptiness plaguing her mouth vanished completely, and was replaced with a sense of satisfaction. She stood up, panting.
