Diana makes some modifications

"Well we have to make a few little tweaks first." Diana said as she moved her hands over Tom's. She had to teach him how to pinch her nipples in this new younger body. But damn did it feel good once he started to actually put a little **** into it.

"What were you thinking?" Tom said, his voice floating out as if he were sleep talking. Every ounce of his attention was on the feeling of these perky new globes of flesh. Diana wasn't sure which was more pleasing, his rough ministrations, or the fact that he was finally starting to figure out the right priorities.

"Au pair, every time time Tom pinches my nipples I want you to pinch yours too." Diana said as Tom began to nibble on her neck.

"Of course Mrs. Miller. Anything you say." the au pair said in a cheery voice that seemed far too bubbly and youthful for the pear-shaped middle aged woman's body.

Suddenly the nibbling became a bite, hard and welcome, as Tom squeezed Diana's nipples between his fingers. Diana couldn't think straight it felt so good, but when the sudden jolt of euphoria ended, she felt proud that Tom had managed to listen while still attending to her needs, as his fingers began to expertly twist and play with her stiff nipples.

He was already growing so much.

Diana turned her head and saw the old version of herself already shirtless as she mimicked Tom's every movement on herself.

The former Sophia Kahn's face now sported Diana's devilishly cute grin as she watched her former body manhandle itself.

"How does that make you feel au pair?" Diana said, her own voice coming out breathy and ragged from the manhandling Tom was so expertly carrying out on her.

"It feels kinda nice! I guess. I don't really know, since sex isn't really part of my duties as an au pair, I don't have much of a reaction to erotic stimuli." she said.

Tom broke off from Diana, when he heard that. Diana herself was confused. Then she realized what this meant.

Fine, a slight adjustment to the plan might actually make this even more interesting.

"But you still take your orders from us right? You're our au pair?" Diana said.

"I'm your au pair, my duty is to help you raise Michael and Jessica and to make your lives easier around the house. I will obey any order to further those goals because this personality genuinely cares for you and your children. Anything outside of that scope is beyond my ability to comprehend at the moment, unfortunately."

"I see. I guess I might have made her character a bit too thin. You were right about that Tom, but nothing we can't fix! Au pair you said you want to make our lives easier around the house? A big part of married life is sexuality. A couple's coital health can be vital in how they rear their children. Something I picked up from Dr. Kahn's memories, but it is true. So obviously making sure we're sexually gratified is an important part of your job. Right?" Diana said.

"Gosh Mrs. Miller, I hadn't thought of that! Your logic is sound." the au pair said.

"Great. Then to better understand our sexuality I want your body to be able to feel arousal, is that clear?" Diana said.

"Of course Mrs. Miller." she said, as her round cheeks began to flush.
