just a bit more background...

He spent a long time with just the one fairy, whom he called Jezebel, carefully imprinting himself as her lord and master. Once he really got into the power trip he even imagined himself as her god. It helped to imagine what he wanted when producing the cum for her, the thoughts left some kind of psychic imprint on the cum that carried over to the fairy. Eventually he let her out of her cage, much to her astonishment. She didn't even try to get away, just stood there looking up at him nervously. Chuckling, he gently stroked her back eliciting a tiny purr as she leaned into him.

As a test he even put her in the open window, looking out towards the glade where he captured her. She looked pained, like she wanted to want to leave. But she turned back to him and waited patiently. He spent some time reinforcing her decision afterwards, lifting her up to his mouth to personally pleasure her. He was rather proud at getting her to orgasm so quickly, her thrashing as he sucked on her legs and drove between them with his tongue was one of the stranger experiences up to that point in his life.

Afterwards she lay gasping in his hand, gazing up at him adoringly. For that look he decided to give her another reward, just to cement the thoughts, and he gave her a well-deserved cumbath straight from the source. She kneeled on the table, mouth open wide, tongue out to catch the oncoming flood... it was beautiful. When he came he blasted her back on the table, covering her in her reward.

It was then that he learned that a fairies power correlates to her belief. When she was captured she believed in herself, she shocked him often and tried to fly away. When he gave her a taste of pleasure she became conflicted and lost her wings. Now that she believed in him, totally and completely, she regained her power.

She grew a different set of wings: compact and sturdy, easily folded so they wouldn't get in the way. And she got her magic back with interest: she could light a candle from across the room with the sparks she threw. More than that, she was capable of other magical feats. He once caught her masturbating with an unnatural looking phallic-shaped mushroom, it seemed to be leaking a thick-white substance.

"Can you do this to other things?"

She nodded sheepishly before realizing his delighted grin. After that she often brought him little bits and bobs she had corrupted with her magic: a violet wasp whose stinger had been morphed into an inseminator, a worm that was quite singleminded in its quest for her pussy, he even had to save her from a purple-veined ivy plant that was using her magic like a battery. It had taken over half the lab before he was able to extract her.

To stop her from hurting herself with her creations he conscripted her help in making more slaves for his little laboratory. She would always be his favorite, she had grown from a submissive **** to a quirky helper of sorts, but he was just getting started with this forest...
