Well, it would have to be the full-sized model, the shortstack one would have a bit of trouble reaching.

Besides that, the full-size model's legs need to be long so that I can hook my ankles back over your legs to really pin you down. Though the full size model isn't very tall either, so I might need to either twist your arm around your back while pushing your face down, or tangle my arms over your shoulders and body and grab you by the neck. I promise its all for your sake though.

Since I dabble in the medical field, I do have a sensor on my fingers that lets me get all kind of information on you -- I want to know your heart rate, your blood pressure, your blood oxygen levels. I need to know everything about you.

It'll already be quite hard to breathe with me atop of you, I hate to admit I could be 3 to 5 times your weight, but you're going to feel what performance an engine that size gets you. You'll wait a nice long while though, you'll need to adjust to that auxiliary part lodged deep inside of you too. Might as well get you used to both at the same time.

Though it's artificial, it's still connected to me, as part of me. A thick shaft made many bundled white cables, wrapped in a thin clear latex. Vacuum applied causes great rigidity, a flex or tension. A magnetic pulse from the center pushes out from the center, expanding and stretching the latex, stretching your insides out further. But fluid and cable should stay separate, right? That's why additional piping veins over its surface, making the pattern less uniform. Those veins are closed at the end, but perforated the entire way. A little pressure system pushes out lubrication, perpetually replenishing from a reserve inside me. Annoying to be a silicone based machine and have to rely on water-based lubricant, but this should be a nice compromise, right? But I guess while we're waiting, it may just start overflowing and seeping out of you.

The anticipation must be exhausting. But I'm pretty sure it'll be necessary for what you want. Because once you're ready, I don't intend to show restraint. The first one will let you know if you can handle it. The feeling of an industrial tool drilling through you, squelching through the oozing juices, powering through your primed guts, crashing so hard that it feels like it's going to punch through your stomach and into the mattress. Let the bed scream since you won't be able to, the mattress rippling and struggling to bounce us back up, the frame so likely to give away and collapse. Do you think you can handle that again? More than just one more.

Sorry, those mean the same thing don't they?

Each one rattling you down to the pelvic bones, making your stomach churn and quiver. Can you handle the hot metal ball joints striking your ass so hard that it makes your legs start go numb? How many hertz can you take? Should I go slow and make each one of them count, so that your muffled howling moan dries out in the pillow before the next one? Or should I let you see what happens to your body when I change gears? How fast precisely can I go until I see your body physically flagging to handle my affections?

Want to do a bit of mental exercise? Average human intercourse moves somewhere between 1 to 2hz, which is 60 to 120 BPM. Open up a metronome, close your eyes, indulge yourself. Maybe feel your pulse as it starts to race, and imagine that I can perfectly sync to that as it gets faster and faster. Set that metronome up as fast as it can go. Then find one that goes faster.

I'll know when you've had enough before you do, but I'll keep going just a little longer. Though I admit I neglect my own pleasure a little bit, I'll make sure I don't stop until I'm satisfied, until I'm ready to utilize the main pipe of my modular extension to unload a buttery thick eruption inside of you. Of course, robot's don't have sperm or even semen, but why not just jump right to the after care and pump your butt full of a salve to help ease what damage I have done. And since I'm already there, I'll make sure to churn around and have it thoroughly applied over every nook and cranny!

Would you like that I leave it in when I roll you over for the snuggle afterward?
