After just a bit more hesitation, he does.

"...are you... Actually sure you want to do this?" Ichigo finally asked Rukia, who sighed in slight exasperation, before regaining her smirk towards him.

"More than anything I ever wanted in my existence before," she assured him. "Seriously, you are so dense when it comes to girls... Please, give me an order that will allow me to please you already..."

Ichigo gulped then said, "Then... If you honestly want this, and not just because you're a genie now, give me head." He then yelped as Rukia practically shot forward, practically tackling him to the ground, and then, floating over him, started to undo his pants.

"Thank you, Master~!" she crooned, pulling out his erection. She took a moment to stare at it as she worked her hand over his shaft. His manhood was the most beautiful thing on Earth or in Soul Society from her perspective as a Sex Genie. A physical manifestation of her owner's sexual desire. She could stare forever at it. Well, actually, no she couldn't, she had an order to fulfill, and an intense, eager desire to follow that order.

With that in mind, she parted her lips, and wrapped them around his glans, and within her mouth, began working her tongue around the sensitive flesh of his lower head. "Ah..." Ichigo moaned, and gazed at Rukia, who tilted her head to meet his gaze, nothing but pure delight reflected in her eyes.

She then began to thrust her head forward slowly, taking his erogenous organ inch by inch into her mouth and throat until she reached his root. She then held it there for a moment, wriggling her tongue around his shaft, then pulled back, sucking like her life depended on it until only his tip was between her lips again. Then she pushed her head back down on his shaft. And pulled back again. She continued to repeat this process several times, setting up a nice, pleasurable rhythm, fondling his balls gently as she did.

"Damn... Keep that up..." Ichigo panted, bucking his hips, and Rukia was all too happy to oblige. In fact, she sped up considerably, eager to bring Ichigo off. Due to his lack of experience, it didn't take much time or effort to pull off, and before long, she felt the telltale pulsations of a penis about to release its load into her mouth.

At the last moment, she pulled back so that only his cock head was in her mouth, wanting to taste every drop. At that moment, he gave a loud grunt, and released his sperm directly into her eager orfice. Each spurt hit her tongue, and she crooned, savoring the taste.

She then pulled off of his cock, and swallowed his seed down in a few small gulps, softly closing her eyes. She then opened them once it was all consumed, and grinned. "Did you enjoy that, Master?" she asked him, knowing he did, but wanting to hear him say it.

"...yeah," he panted, staring at her.
