Excerpt:"This is the problem with fairies, " said Cybelle, mostly to herself. "They're always willing to hop into bed with their next new partner."Doesn't have to be a bed, " said Daisy as she reached up and untied the string that held her blouse closed. Because of their wings fairies were somewhat limited in what they could wear around their torsos. After she dropped the cotton blouse the rest of the garment fell to the floor and she was naked.
Shifty took in her lithe body and quickly decided bedding a female fairy would be decidedly easy."I do believe she wants to have sex with you, Shifty, " said Cybelle."And you too, " said Daisy. "That'll make it interesting. Three in a bed.or elsewhere."Cybelle watched in fascination as Shifty, in the form of an elf, and Daisy kissed. It was like old lovers meeting and Cybelle felt a thrill of jealousy mixed with uncontrolled lust.
She wasn't sure where here jealousy lay since she had bedded both Daisy and Shifty, but told herself that Daisy was just a passing fling and Shifty was.she couldn't have a long-term relationship with a shapeshifter.
