Of course.

"Like what?" Bill asked. The question had caught him off guard.

"Well," she said mildly, "as you know, I'm able to manipulate this body at will. Earlier you asked me to enlarge my breasts. I can modify it further - for example, widening the hips, lengthening the legs, altering the face. I can do even more **** things than that, though. I could grow a penis, or a second vagina. I could relocate my orifices to different areas. I could even become an animal for you. Do you have anything you'd like me to do before you have sex with me?"

He stared at her in shock so she continued. "You've also noticed that I can change my presentation. You seem very aroused by my current compliant but simplified affectation. I could become completely robotic again, or take on any number of personas. I can change any of these things before, during, or after sex. As the old saying goes, the sky's the limit."

"Wow. Ok, I- do you have any suggestions?"

Amber smiled placidly. "Judging by your erection and quickening pulse, I suggest you have sex with me immediately." When he nodded, she leaned forward to kiss him.

When their lips locked it was nothing like what Bill had experienced before. Prior to that, this strange creature had brought all of its arts to bear on pleasuring him. Every move, every sound, every detail was completely calibrated to bringing him maximum pleasure. This just felt like kissing his wife after she'd had a long day at work.

"Could you, um, be more enthusiastic?" he asked as they ended the kiss. She nodded, then surged forward as though attacking him. She took him by surprise and they tumbled onto the ground, where she grabbed two handfuls of his hair and shoved her tongue into his mouth. Her legs were writhing around his. "Take my clothes off," he grunted and she obeyed.

She hastily unzipped and shucked off his pants, then tore off his boxers. He yelped in pain as the cheap fabric ripped but was cut short as she pulled his head to her chest, forcing his head between her bouncing tits.

"Is this enthusiastic enough?" she asked guilelessly. He tried to answer but was smothered in her chest, so he simply gave a thumbs up. He felt her seize his hand and place it on the small of her back with some **** while she ground herself against him. His dick instantly felt wet and it occurred to him that she could lubricate at will. He surged against her and she reciprocated, the carpet scraping his back as she impaled herself on him.

"This is the first time I've done this in a long time," he gasped as she rode him. "I can't believe I'm doing it with you."

Her eyes closed in simulated ecstasy, she replied instantly. "There is no me."

He felt himself twitch inside of her at that and recognized that he was turned on by her emptiness. "Yeah?" he asked lustily. He grabbed her hips and bucked against them. "Then whose hips are these?"

She lurched forward, her breasts swinging wildly and her untamed hair tickling his face. "Yours. They're yours, Bill."

He grabbed her soft, firm tits and pressed, pushing the flesh back against her chest while she grunted and writhed. "How about these tits? These are mine?" She nodded and he replied. "Then make them bigger."

Under his hand, each breast swelled slightly. Bill could actually feel the changing weight, as though he was holding a water balloon while it filled. Their pace was becoming frenetic and he was panting with exertion.

"Now smaller!" They reacted instantly, shrinking slightly to slightly more modest handfuls. "Now in my face!" She grabbed his head and, with inhuman agility and dexterity, brought him once again to motorboat her.

Through her cleavage, he cried out again. "Tell me what you are. Exp-unhh-explain it to me!"

Her voice husky and quavering, she told him. "I'm not a person, I'm not a creature, I'm not an entity, I'm a thing. I- umf - I'm a piece of pure ontology, with no beginning and no real relations."

He was about to climax and he bit down on one nipple without even thinking about it. She pulled his head back as though to chastise him and looked into his eyes.

"I am nothing, and you are everyth-"

He interrupted her with a cry as he erupted into her, feeling his seed drain to the last drop. As he spasmed out the last of it, he fell back and his head hit the floor with a painful thump. He was utterly exhausted and ached all over. Amber looked down at him, still on top of him in cowboy position. She was flushed and sweaty. It occurred to him that, like everything about her, this was just for show.

"...everything."
