Just for her, Zoey would become a robot. She put on the costume, well bodysuit really. Created in a collaboration between Akari’s savings and some contacts Zoey still had from her modeling days with the sole purpose of fulfilling the former’s fantasies.
Most of the skintight bodysuit covered her body from her limbs and back up to her full neck, with a few small patches even going over the edges of her face, in a metallic white with lines in black or electric blue. Her limbs in particular came with added details to make them appear like robotic doll-joints. The chest held a big prism-shaped cut-out covered in transparent latex with a light blue tint for her breasts and crotch that gave a great view of her nipples and vagina (and a hidden hole for easy access to the latter). Zoey’s favourite detail though were the slight push-up effect the suit had on her breasts and butt, even if her body didn't need it.
The last two pieces had to be put on separately. First a pair of fitting headphones to cover her ears. Their headband had cat-ear shaped protrusions. The second was a clear mask to give her face a synthetic look. Their only other feature was a barcode under her left eye. With a few satisfying clicks all three pieces connected, completing her transformation into ZO-3Y, Akari’s personal robo-doll, nicknamed “Zoey”. She went back to the living room, of course having no problem with the suit’s built-in high heels.
Sitting down on the couch she started rubbing her chest a bit. While the robo-doll was entirely for Akari, she had to admit she got a kick out of playing with her latex-covered features. Saying she hated it might've been a bit too much. Though she stopped herself before going too far. Wouldn't want Akari's present to get wet. Well, too wet.
Half an hour later the sounds of the door lock gave Zoey the signal to start. Positioning herself in front of the door, she stood perfectly still with her hands in front of her.
“Sorry, I’m so late, hard day at work…” Akari groaned as she slowly trudged in, still in her sübusiness suit. Even in this state Zoey found her incredibly cute. “You won’t believe what Rhonda did–” She finally looked up. She stared at Zoey, mouth agape. “I-Is it already… But… Oh my god, I completely forgot.”
“Happy birthday, master,” Zoey said in as much monotone as she could muster at the moment.
Akari ran up to her and caught Zoey in a deep hug, giving her a small peck on the barcode. “Oh, thank you, you're so adorable, I don't deserve you. I love you so much. Is there any way this could become even better?”
“As you wish, master.” Zoey took a step back and knelt down. When she was young she never expected she’d propose in a latex robot costume, but if that wasn't a sign of her love for Akari. As she produced the boack box and opened it, Akari's eyes went wide. “Akari, you are the kindest, friendliest, most generous woman I know. The last few years with you have been the happiest in my life. You took in me, a failed model, and made me feel like a princess without asking for anything in return. If it makes you happy I’d wear this costume for the rest of our lives, but I fear the novelty might run out. I might not be able to give you the robo-doll of your fantasies, but what I can give you is myself. Will you marry me?”
Hands in front of her mouth and tears welling up in her eyes Akari stuttered, “P-P-Please t-tell me this isn't part of the roleplay.”
Zoey simply nodded.
“Y-Y-YES! I do! I do! I love you!” Akari threw herself at Zoey again, this time their lips locking in a deep kiss as well. For a full minute they were just kneeling in the hall and enjoying that taste of their mouths. As they finally had to part to breathe, Akari whispered into Zoey’s ear, “Are there any more surprises, my dear fiance?”
“I prepared your favorite cake, master.” Zoey tried her best to stay in-character, but it was clear that neither she nor Akari were in a fitting emotional state to properly continue.
“Then let’s taste it, my dear doll.”
Another beautiful smile came over Akari's face as she saw the cake. “Even with candles, you really didn't have to.”
“Make your wish, master.”
As Akari took a deep breath, Zoey noticed that despite burning for quite a while already the candles hadn't shrunk a bit. Her grandmother's words rang through her head again. Blowing out the candles would fulfill someone's deepest wish. But that was just a joke, right? Still, a small part of Zoey couldn't help but worry as Akari blew out the candles.
