BDSM Scenes, Step-by-Step: DIY Sex Robot Roleplay

Here we are with another BDSM Scenes Step-by-Step post. Today, we’re focusing on making DIY sex robot fantasies come to life with help of some sex machines. This simple, step-by-step outline gives you everything you need to make a fantastical robotic sex scene come to life with the reasoning behind it, how to modify it to fit your vibe, what stuff you need, how to prepare for it, how to do it, and safety concerns.

This BDSM scene outlines series exists because I remember what it was like when I first stepped into kink. It was terrifying to identify as a “Domme“. That’s where I felt like my heart was, but it simultaneously meant that I was supposed to know what the fuck I was doing despite being brand new myself. It was so much anxiety!

I remember doing tons and tons of Google searches, hoping to find someone who had made something prewritten for me to follow. I just wanted something to alleviate my nerves. I wanted to be the one in charge, but the idea of doing everything, from start to finish, in an activity I barely knew anything about, felt terrifying.

Now that I’m a less-baby Domme, I’ve been writing out these BDSM scene outlines for the past few years. Think of them as a quick scene starter to get your inspiration moving. Take what works for you and dump out what doesn’t. Let these outlines help you grow your confidence with being in charge until you, someday, are writing your own!

Now, let’s get into how to bring a DIY sex robot fantasy to life…

This Scene Is….

A real-life way to bring a fantasy about being fucked by robots (or machines) to life. We’re trying to remove as much of the human element as possible while playing up the “at the mercy of these robot” vibes.

Since we’re humans, we’ll never “really” remove all of the human aspects or truly be at the mercy of sex robots who just want to hump us. We can do some things to roleplay the scene, though, bringing some of those fantasies as close to life as possible. Just like using a Sugar Daddy website to try to find a sugar baby relationship, we’re using the tools at our disposal to bring desires to life.

The biggest hurdle for this kinky scene plan is the fact that it requires a sex machine. I have an entire article (Are Sex Machines Worth It?) that I highly recommend reading, but the basic gist is that super-cheap sex machines can be more frustration than fun. If your budget doesn’t work for a medium-cost sex machine right now, consider some of the automated toys I mention in that article as alternatives.

When I have played out this scene in my own bedroom, I’ve used two separate sex machines. As long as you still do the work with dirty talk and scene setting, you can really make this work with any type of human-removed toy. (dick on a stick, wand massager vibe, hands-free insertables, etc.)

This scene is very focused on overwhelming your bottom with sexual pleasure alongside a small bit of bondage. You’ll want to be sexually intimate with anyone you do this with.

What Do You Need for a DIY Sex Robot Scene?

To do this scene, I’d recommend:

• A spot where your bottom can kneel for a long period of time
• At least one sex machine – code HISMITH10 will get you 10% off a Hismith option (I use a sex machine to thrust a dildo into the butt AND a sex machine on the front to thrust a penis stroker onto their shaft. You can easily get away with one sex machine doing the thrusting and a wand massager saran wrapped onto a piece of furniture for hands-free holding if you’re playing with someone who prefers external vibrations)
• Sex machine dildos/attachments
• A lube for your partner to ease the friction of the sex machine (even if they rarely use lube!)
• A pair of easy-to-move-in gloves for yourself. Get multiple pairs if they’re disposable (i.e. you might tear them mid-scene)
• A blindfold
• Wrist cuffs
• Fastening gear (rope/tethers/chains) to attach your wrist cuffs to a bondage point somewhere
• Other bondage gear to match your “vibe”
• A container to catch semen (if applicable and matches your vibe)

You’ll really want to flush out the backstory of your DIY sex robot scene. Why are you, this human, involved? After all, a DIY sex robot wouldn’t really need a human around. Your backstory will vary based on what flavor of robotic sex you and your kinky lover are into. Some examples:

• If you both are turned on by robotics in medical settings, a human as a doctor in a clinic makes perfect sense and requires no further explanation.
• If you’re turned on by a sentient, futuristic robot “doing things” to humans, it might make less sense for this sentient robot to need a human. In that case, you may wish to build in backstory like “we have seen that humans respond better to faces that match their own. Please meet my assistant”.
• If we’re going for “romantic robot who wants to make you feel good things”, you might want to plan for a backstory like “I brought in an assistant to help make sure you feel comfortable. I care a lot about making sure you feel safe.”

How Long Does It Take?

This is not a scene you really want to rush. Plan for at least an hour of active “scene” time with at least 45 minutes prep time for getting your house ready.

Realistically, this is just not a scene you’re going to want to do if you’re on a time crunch. The whole point is overwhelming your bottom with lots and lots of overwhelming sensations with the help of automated sex toys. It’s hard to really build that fantasy world (and let them relax into it) if we’re worried about having to make a dinner reservation in 3 hours.

How Do You Prep for a DIY Sex Robot Scene?

We’re going to send your partner out of your house to give you time to set up your BDSM scene.

This scene will not have the same immersive qualities if your lover can watch you set up the whole thing. Instead, send them out and make sure they know they’re coming back to a sexy activity to ensure they’re in the right headspace.

To set up, I’d recommend:

• Picking a spot in your house where you want to set up and want your partner to kneel for a long period of time
• Setting up one sex machine (or a wand vibrator) to rest in front of them
• Setting up a second sex machine (if applicable) to rest behind them
• Ensuring both controls for the sex machine are in the same spot for you to easily control
• Ensure your bondage point is ready and accessible. I use an overhead bondage point. You may wish to put a chair on top of the front sex machine, giving them a sturdy surface to lean onto. (like this)
• Get the blindfold and wrist cuffs out.
• Clear out the walkway between the front door and your sex play space, removing any clutter or visual distractions. (i.e. If there’s a pile of clothes on a bedroom chair, put away the clothes. Visual clutter is going to mentally distract your captive away from the scene.)
• At a minimum, change clothes. Ideally, change into a costume or outfit that matches the vibe you’re going for.
• Slip on your gloves. We do not want your partner to feel the warmth of any human skin.
• Set the house’s ambient factors as mentioned in the “What’s the Vibe?” section right below.

I’ve primarily done this scene in a spot in my house where I can bind my partner’s wrists above their head as they kneel. For good measure (and to allow them to really sag and get lost in the sensations of the sex machines without pulling on their shoulders), I also reinforce this with a rope chest harness attached to that overhead bondage point. You may not have an overhead bondage point. Mental bondage, or other types of bondage, can also work too.

Remember: if done “right”, your partner is going to be extremely overstimulated and exhausted by your DIY sex robot. Make sure they have a way to relax into the position you’re going to place them in.

What’s the “Vibe” of your DIY Sex Robot Scene?

There are lots of erotic ways a DIY sex robot scene can go. The exact way you want to set up your apartment will depend on the vibe you’re going for. Is this an autonomous sex robot who kidnapped the bottom and needs to milk them for sustenance? Is this a medical appointment where the nonplussed doctor uses multiple machines to apply a “treatment”? Is this a romance-seeking sex robot who is utilizing its limbs to make someone feel good?

The roleplay you’re looking to replicate will really make a big difference in your initial setup. Some ideas:

• Change the temperature. A medical, torture-focused, unforgiving vibe works best with colder temperatures. A warm, romantic vibe works better with warmer temperatures.
• Change the lighting. Harsh, rough lighting (like a medfet scene!) is great for that clinical vibe while dimmed lighting with some neon undertones can give you more of a “sexy” vibe.
• Swap up the attachments. A sex machine doing super-slow thrusts with a rigid, plastic “dilator” (i.e. a dildo, but swap up the name for headspace purposes) will work for your doctoral vibes while a pre-warmed realistic dildo might fit better for sensual vibes.
• Change the location. If you’re lucky enough to have multiple places to play, you don’t have to play on the bed. Doing this on a paper-covered massage table can be great for clinical vibes. For “robotic overlords who don’t care about your comfort”, you can easily swap to doing things on a hard tiled floor.
• Choose your outfit. Are you a professional assistant wearing business casual? Are you a “human sex toy” the robot has used to try to make the “captive” feel comfortable? (If so, lingerie or kinky gear might make more sense) If you’re in a hospital setting, that Halloween clearance doctor’s coat might come in handy.
• Pick a soundtrack. This one can be harder to “nail”, but if you think there’s a specific vibe that would work best for your DIY sex robot scene, you can grab some background music to help really drill it in. Keep it low for best effect; someone should easily forget it’s there, but it’ll work subconsciously. Medical scenes can have hospital background noise. Futuristic scenes might benefit more from “empty space” type of noises.
• Contemplate pre-recording robotic voice commands. If you really wanna go balls to the wall on this, avoid using your own voice, instead utilizing voice-to-text robotic voices to give you all of the phrases you want. You can save, title, and load these voices as .mp3 files on your phone and hook your phone’s sound up to a home sound system. You can then utilize these files to make your DIY sex robot feel like it’s actually “there”. Keep the voice-to-text website available to type out any additional commands if needed. At a minimum, using this can be helpful to explain your backstory when your partner first walks into the room. You’d then only need to pre-record a single message as a story introduction.

Step-by-Step Instructions for a DIY Sex Robot Scene

1. Spend the weeks preceding your scene date by hyping up the idea of a sex robot. Presumably, if you’re doing this scene with a partner, you (or your partner!) are already into the idea of robotic sex. We really want to get them fantasizing about it, though, so mental images are fresh in their mind for the scene. Find some animated porn or erotica that features robotic sex. Since there’s only so much we can do in the “real world” in our bedrooms to replicate this, we really want their imagination to do the bulk of the work.
2. The day of your scene, ask your partner to go out for a bit while you set up. We want them to go out and do something relaxing. Ideally, they may know that they have a “sex appointment with you” when they come back, keeping them turned on. You can assign some hot robotic sex erotica for them to read while they’re out if you want. When they come back, ask them to knock on the door.
3. While they’re out, get your house ready for the scene. Set out the machines, set out the restraints, prepare your house, and get yourself dressed into whatever costume or vibe you’re going for. I have that checklist above in “How to Prepare”.
4. When they knock on the door, prepare to greet them in a way that matches your scene vibe. A cold doctor would succinctly welcome their patient. A warm robot who is thankful for your “donation” would be robotic…but they’d also be friendly and patient.
5. Without much delay, request that they remove their clothing. Again, match your vibe. A cold doctor will say a few phrases and say “I now need you to undress”. Whether your doctor leaves the room is up to you. A warm robotic lover would patiently wait or make notes about how “they can only make you feel good if you get naked”.
6. Now that your bottom is naked, place the wrist cuffs on them. You can add additional bondage gear, as desired, but this scene outline only really requires a single set of wrist cuffs.
7. Lead your bottom to the area where the machines and bondage gear are all laid out.
8. Request your bottom to get into position, using phrases that best match the vibe you’re going for.
9. Once your bottom is in position, bind their wrists to the bondage point you’ve selected when setting up your space.
10. Blindfold your bottom. Again, utilize phrases that help best sell your vibe. A doctor may say something like “We’ve found this treatment is more effective if a patient is able to focus on the machinery.” while a DIY sex robot focused on milking its captives may say something like “The human mind provides itself with better fantasies when its eyes are closed. We’ve found that fantasy fulfillment provides a larger resulting collection.”
11. Now that they’re captive and bound, this is a great spot for any words, robotic or otherwise, that help explain your backstory. We, quite obviously, are not robots. So your only way to really “sell” this roleplay is by utilizing your captive’s imagination. Give them as much fantasy fodder as possible to hold onto. Why’s the robot holding them there? What’s the robot’s end goal? What’s going to happen to them now? Use that robotic text-to-voice we set up earlier, or use your human voice as the robot’s “assistant”.
12. This is where you would perform any other additional things that help sell your backstory. If your robot is a warm, sensual lover who wants to see what human sexuality is like, they’d probably start with foreplay, rubbing and squeezing parts of the human. If you’re in a medical setting, you probably need to take some measurements, ask the patient’s date of birth, and receive “consent” for these treatments. A DIY sex robot that is just here for ejaculation extraction won’t bother with much foreplay, and they’ll probably just start stroking the patient’s shaft so that semen extraction may begin.
13. When you’re ready, start by getting the “front” sex machine in place. Penetration vaginally or anally is going to feel best if your partner is already turned on. We can utilize this front sex machine (or wand/vibrator), focused on the penis or clitoris, to get the captive’s arousal higher.
14. Feel free to move/adjust your captive, as needed, to get them into the place you need to get the sex toys in place. For a penis owner, that may mean getting them to spread their thighs (to get to a lower overall height) or bend over (to accommodate an upward pointing penis). For clitoral owners, you might need the same adjustments to get the toys in the right place. Again, you can do this within the vibe of your roleplay. A doctor may ask the patient, matter-of-fact, to move. A romantic robot may gently pick up and move the limbs.
15. If you have another toy you’d like to use instead (or in addition) (a Lovense Lush, for example), this can also be a great place to get that set up. We’re aiming to add as much hands-free, automated pleasure as possible.
16. Once you’ve set up the single machine, sit back and let your partner enjoy it for a bit. I recommend keeping the speed settings low, letting them get accustomed to the sensations without going over-the-top (yet). Feel free to pepper in more words that reinforce the DIY sex robot vibe that you’re going for. Add lube as needed.
17. When you think they’re ready, get to work setting up the second sex machine (if applicable). In my outline here, we set up the first machine to do a lot of external pleasure while this second one will be used for vaginal or anal penetration. Of course, feel free to adjust things as needed.
18. I recommend turning off the first sex machine/toy and using some dirty talk or phrases before sliding the second machine inside. This may be medical speak with “We need to use another machine to improve our accuracy.”. This might be “I want to see if humans can feel even more pleasure at once”. Reinforce your captive’s mental picture by giving them a reason this kinky robot wants to add even more.
19. This is also a great time to add more lube.
20. When you’re ready, get that second one slid inside, and start up only the second one. Especially as getting penetration angles can be a bit more finicky when sliding inside than with your first item being external-only, you may need to adjust the machine or your partner’s positioning.
21. When they’re settled into that second one, start the first one back up, keeping them at low settings.
22. Give them time to enjoy themselves before ramping up the intensity. Add some words (if desired), giving them reasons the robot wants them to have more pleasure. Alternatively, if you find your captive is already getting close to orgasm, you can also have reasons that your DIY sex robot doesn’t want them to orgasm, ceasing stimulation.
23. Bring the intensity up to medium, and gently back down, for a few cycles. Don’t forget to add lube as needed!
24. At this point, if you have any additional sensation play items you want to add, you can add them by hand. Try to avoid touching the person with your own warm hands. Quick ideas: nipple clamps, ice along the skin, wax play (do NOT get it on the machines), clit or testicle clamps, wartenburg wheels (be careful if they’re squirmy), additional vibrators.
25. With all of that going on, they’re going to get overwhelmed with sensation here. Be prepared to turn down (or turn off) the machines as needed to control the pace of the scene. If you have something vibrating, be prepared to turn it off entirely (or turn it to a pattern) to avoid numbing the area from over-vibration. Expect them to sag or lose the ability to easily support their body weight as well; we don’t want them to fall or tear a shoulder joint.
26. When you’re ready, start prepping your captive to orgasm with words. Why is your DIY sex robot going to let them cum? Is it the culmination of the medical treatment? Are they milking them for their own needs? Do they want to see what happens when a human has an orgasm? Even more intense, do they want to see how many orgasms a human being can experience? (you sadistic orgasm torture robot you!)
27. After you’ve set the scene with your words, start to increase the intensity of the machines and toys. Let them climb up to that orgasm, and make sure to add in words about the robot’s intentions to really drive home the fantasy and visual they have in their head.
28. Once they’ve had an orgasm, you can either consider the scene done OR you can ramp them up for more orgasms or sensation. If you want someone to have multiple orgasms, you need to continue some form of primary stimulation (usually clitoral or penile), but they’re going to be very sensitive. We have to prevent them from going into the resolution phase. So make sure you pull down the sensation to very light while still having it there. Give them a minute-ish of variable, light primary stimulation while changing up stimulation elsewhere before ramping back up intensity to see if you can draw out more orgasms.

Pre-Written Dirty Talk

It’s going to be really hard to give you generic dirty talk sentences that’ll work for every vibe of DIY sex robot scene out there. It’s really going to depend on whether you’re going for degrading or loved, whether your robot is sentient or not, and whether your robot is part of a fantastical futuristic scenario or something a human being is “using for a treatment”.

Instead, I’d really, really, REALLY recommend sitting down before you do this scene to figure out what you want the backstory to be. Why does your sex robot want to have sex with this person? How did your bottom end up at the mercy of this sex robot? What role do you (the human) play to the robot? Is your robot a generic robot with no personality that’s purely acting on orders, or is it a robot with sentience that’s getting to explore something that it wants to do? Does it view its captive as an interesting science experiment, a new play toy, or something it just has to get it over with as part of its 9-to-5?

Once you have that, start thinking about phrases that might work within the context of that story.

To make it easy, I’ve tried to note spots in the outline where you can really play up the contextual scene you’ve made. In general, just think about why your robot would be doing what they’re doing, and verbalize it to your partner when you’re changing things up.

Why would the DIY sex robot want to increase the intensity of the sex machines? Why would they want to add nipple clamps?

You can also come up with a few phrases that essentially mean “good captive” but work within your roleplay scenario. For example, a doctor may say something like “You’re doing a great job. This treatment can be intense, but I promise it’s almost over.” A robot that is trying to extract as much semen as possible may say something like “It looks like your balls are getting even fuller. Good subject. We need maximum extraction.”

It can be easy to pepper in those phrases when you’re at a loss for something else to say.

Add-on Fun for a DIY Sex Robot Scene

As always, the world is your oyster when it comes to whatever you want to add within my scene outline. Please, take my outlines as inspiration and add in whatever cool stuff makes you and your captive happy.

Some quick ideas:

• The DIY sex robot had such a great time that they now have no interest in “sharing this human” with anyone else. They introduce a chastity cage or chastity belt to lock the human in afterwards.
• For gooning fetishists, you can easily skip the blindfold and play hentai or animated porn of sex robots having sex with their captives. If someone tends to depend more on visual images than their own brain for this type of stuff, this can be a really easy way to really “drive home” the DIY sex robot theme. Try to preview the porn and get all of the movie’s “vibes” to line up. i.e. If you are jumping from clips that are really sadistic to really romantic or sensual, you’re going to have a hard time keeping up with one cohesive “vibe” for your dirty talk during the scene.
• If someone has an ignore kink, you can fit this into your robotic vibe as well. The robot is a bored factory-line worker, and they have yet another human being to milk. Yawn. You’ll get them all set up, but the vibe will be very detached and bored, going for extreme efficiency.
• Feel free to get creative if you don’t have two sex machines. We’re really just here to add a whole lot of intense stimulation at once while removing you, the “human” lover, from the equation. This may mean that the robot sets out a sex doll for the captive to have sex with while the sex machine does its job from the back. This may mean that the captive is told to hump or grind up against a pillow or firm surface while a sex machine does some work from the back.

In general, I really recommend having a vague understanding of what gets your partner off about robotic sex before jumping into this one. Usually, it’s some specific feeling of helplessness they want to feel. Is it degrading to be forced under a robot’s arms? Is it exhilarating to be underneath a “lover” that doesn’t have physical limitations? Are they turned on by being more thoroughly used than a human being can capably provide? Are they simply turned on by robots, as a thing, and want to have sex with that thing?

Having that information really helps guide how to personalize the scene and make it unforgettable.

Cautions

Your biggest danger here is friction burn and residual soreness afterwards. Really. Machines give zero shits about lube, and they will keep thrusting and humping regardless of how unpleasant it feels to your captive. Make sure to apply lube often to keep things slippery instead of painful.

You may also want to warn your captive that they might feel sore the next day, and you probably want to avoid penetration for a few days afterwards to give any sore tissue or microtears a chance to heal. Again, sex machines do not have a human touch. They can be rough, and as you’re not the one “feeling” them, you may not realize it when it’s happening. Your captive may not either, as they get lost in the scene you’ve built around them instead of laser-focusing on sensations.

There’s also a light risk of your partner tipping over. There’s going to be a LOT of intense sensations happening at once, and it can lead to slumping or forgetting to hold yourself upright. That’s why we’re doing this scene from a kneeling position on the ground. Even so, ideally, find a way to support most of their body weight so they can really focus on the sensations. I mention that chair to lean onto (which can be really helpful!). You can also use an overhead bondage point to help support the chest upright. It’s up to what you have available and what your vibe is.
