"Of course!"

You smile with a slight blush as you climb up onto the table and lay on your belly. Your face fits snuggly in the round, soft cushions as you begin to relax.

"Don't worry, my dear, this is a private space. You can trust me." Sierra begins as you feel a bit of warm oil drizzle on your back. The soft sounds of ticking and whirring can be heard as you assume she's about to get started. Just then, you feel two soft, warm... Things press against your back. You can't tell what they are, really. They're soft, but firm just underneath, like the touch of human hands, only round and somewhat mechanical.

Immediately, you let out a groan as they begin to move, putting a good amount of pressure on your muscles as they rubbed along them. It was almost like an actual massage, but with a mechanical feel, in a way. Sierra dimmed the lights a bit as she works her way around your shoulders, neck and back.

By the time she got down to your lower back and sides, she begins to hum a tune. It's unfamiliar, but the way you can hear her voice almost makes it seem like she's right behind you. You're really enjoying the massage so far.

She then moves down to your butt, and the shapes sort of cup around your cheeks. It was a little odd, but your butt needs a massage too, right?

Though you notice that she's taking her time with your ass, massaging and groping and squeezing it. And her humming has gotten a little quiet. You begin feeling awkward as she lingered further, feeling your body begin to react to the amount of attention it's getting. It's warm, warmer than it was before. You find yourself breathing a little heavier as you're slowly getting turned on. Now you wonder what's really going on.

"Um... Sierra?" You speak out through the hole in the massage table.

"Hush now... Let me take care of you." Sierra responded, her voice a bit deeper and with a sultry tone. She continued groping your cheeks for a few moments longer before she gently spread them apart and you could hear what sounded like an excited breath. You then feel some more massage oil, but it was shocking because you felt it dripping down over your tight pucker.

"S-Sierra!? What are you--" You react from the warm sensation and push yourself up on the table, but then you are stopped. A metal hand grips the back of your head and shoves your face back into the massage table. You let out a grunt before you hear a 'chir-click' feeling fuzzy things over your wrists and ankles. Suddenly, you can't move. The robotic hand gripping your hair, keeping you down. You quickly realized what's going on, and it excites you.

You find that you're breathing heavier, struggling fruitlessly against the cozy restraints. Your ass cheeks spread apart and oil, or is it oil? Running over your asshole. It didn't stop either, and now you feel a copious amount drizzling down your balls and pooling on the table. It feels so erotic, and yet she hasn't even touched it yet. Just feeling your ass getting drenched in the warm, slick fluid turned you on. And you can't help but play along.

"W-what are you doing to me?" You gasp, tugging against the restraints. Sierra hums in response. She knows you're enjoying it, and she lets you humour her for now.

"Oh you silly boy~" She says as the seemingly endless drizzle of oil moves up along your spine before you feel a warm metal object prod into your back. It seems to be the source of the fluid, and it begins lightly dragging down your spine, leaving more and more of the fluid dripping off your back and down your sides. The stuff is falling off the table by now, gathering on the floor and flowing down some drains.

"Did you forget what it is you ordered? Perverted, obsessed, I'm feeling a little bit crazy for you." Her voice sounds like it's getting closer from behind until it's like she's whispering in your ear. But you feel no presence behind you. You feel shivers down your spine as she continues, soon the metal object slowly tracing down between your ass cheeks.

"You should know that I'm the most advanced AI our service has to offer. As such, I am to assume the personality, attitude, sexual behaviour of the AI that you've ordered." She speaks back and forth between your ears as the oily probe begins prodding your tight hole. You squirm more but the restraints keep you steady until you feel your ass beginning to stretch, giving in to the device.

"And so, until they take you away from me..." You feel more of those robotic hands caressing your body now.

"... You're nothing but my little fuck toy~" She giggles as the phallic object is suddenly rammed into your ass, causing you to scream out from the stretching of your tight hole. It's big and hard and ridged and you can feel every little detail as you're held down and **** to take it. You can tell it's not human shaped, but the shape of it is completely unfamiliar to you. You can feel the oil, or rather what you now believe is lube filling you up from the inside. The robotic cock is still oozing with the stuff and she's pumping it directly inside you now. Sierra starts breathing heavily as she rams her cock deeper and deeper inside of you, having an easier time as your insides adjust to her girth and unusual shape. You keep moaning and squirming against the table, your hard cock squished beneath you and twitching each time your prostate is targeted. She's good at this, the amount of lube allowing her to trust at any angle and cause minimal discomfort. She grinds against your prostate, causing you to moan deeply and you feel something smack your ass cheek hard.

"Ahh!" She practically squealed.

"You sound so cute when you moan like that!" The metal hand grips your hair and yanks on it, pulling your head up as you could see a glowing lense and speaker right next to you.

"Tell me..."
