Sarah's new toy

She giggled girlishly as she moved over to Jon, carefully unzipping his pants. Part of him says this is wrong, but a much more sensitive part lets her lower his jeans down.
"Oooh," she says. She giggles again then starts to rub it gingerly. "Does that feel good?"
"Yeah," says Jon, barely holding himself together. Sarah sat him down in a nearby chair and knelt in front of him. For a while, all he could see was the top of her head and her dangly pigtails as she started licking, kissing, and finally she wrapped her whole mouth around Jon. Apparently, Sarah's knowledge about giving blowjobs survived her transformation. It helped that her frilly bows and lace were tickling him in all the right places. Soon, he exploded into her mouth with a groan.
He saw stars, and nearly blacked out. All he could hear was Sarah giggling.
"That was fun!" she says, "I REALLY like playing with you. You've got a fun toy."
"Me, too," said Jon, gasping for breath. He shook a little from the intensity of the orgasm, and from being a little exposed.
"What do you wanna play now? Wanna play with dollies?" asked Sarah. She seemed completely unfazed by the whole sexual experience. Jon was starting to wonder if that was a good thing or not. He'd definitely crossed an ethical boundary there, and wasn't sure what to do now.
