Fi needs help, and Link goes all the way.

Watching somewhat intently as his own body tried to masturbate, Link sighed at how clumsy Fi was at the task, still unsure and not used to her new flesh and blood body and masculine genitalia. Then, something occurred to him: at the moment, it was Fi who was the master, correct? And she was having trouble with a task, correct? Then, as her servant, it was only logical for Link to assist her in any way he could. Of course, there was something else, something more primal than logic in these thoughts as well. What would it feel like? Link's eyes couldn't seem to move from his previous body's cock, erect and hard and a rock.

Unable to float there and do nothing anymore, Link wondered if he was able to create a pussy for this body in the same way he had arms, and his answer was immediate. He felt as the inside of his pelvic region shifted and changed, an entire female anatomy forming, and finally the lips of his new pussy formed on his crotch, and as he was bending over, showing off his beautiful blue ass to Fi, his new pussy lips were in plain view of her sight.

Sure enough, Link watched in silent satisfaction as Fi's pace began to pick up, her eyes having shifted to Link's pussy. Then, out of nowhere, Fi told Link that he needed help, and as his master she wanted him to help, now.

The response in Link's mind was immediate. He knew now that he absolutely had to help, it was a requirement. Smiling just a little, Link said in Fi's robotic tone of voice, "Master, how would you like me to assist you in your carnal recreation?"

Link wasn't the only one enjoying this roleplay, as he could tell from Fi's face as he spoke. Also immediately, Fi told Link to land on the ground, and bend over. Excitement of several different varieties pulsed through Link's body, and he complied by landing on the ground and positioning himself towards Fi, his face and torso lying flat on the ground, his ass in the air, his pussy clearly exposed. Fi was never one for wasting time, and immediately walked up, positioned her cock just outside Link's entrance, and thrusted inside.

If someone else would have asked Link to describe the feeling of having a cock resting just outside his pussy, the tip teasing his lips, the tension only broken when it thrusted inside, he would have come up completely empty. Words failed. They should have sent a poet. As his own former cock filled his new pussy, Link's mind went blank. There was nothing but pleasure as he felt Fi's cock moving back and forth inside of him as it's current owner thrusted, her hands groping Link's ass as she did so. Unable to control himself, Link found himself moaning out, "Master! Oh, Master, it feels so good!" And it did.

Of course, Link's original body was still young, and not very experienced in the ways of sex. He had never had the chance to build up any sexual stamina, and Fi was unfamiliar enough with it that at Link's moaned words, she had reached the edge. Link could tell as her grip fastened harder onto Link's ass, and she fucked him harder and faster than before. Link could feel the cock inside him swell up larger, feel it tense up inside him, and as Fi orgasmed, filling his pussy with her cum.

As for Link, she did not get a chance to orgasm, though then again, as she thought about the issue lying next to a sleeping Fi, it may be possible that her sprit body wasn't capable of the chemical reaction. While Link was not able to sleep as a sword spirit, she still felt it would be polite to dematerialize back in her sword. In the morning, when they both "awoke", they found...
