Part 23: Saline Infusion / Inflation Play

Please don't read it if you are not
interested in learning about:
saline infusions , scrotal infusions,
and medical play

"Ms160 whenever we go to play parties
these days we see medical injection / infusion scenes ...
they are pretty intense for newbies to watch.
Can you tell us about them?"

"infusion is wonderful"
(private correspondence to Ms160)

The regular reader of this blog who wrote the top quote in red above is quite right. Infusion scenes have become increasingly popular amongst the kinky community.

Scenes often occur at parties - in fact at a recent party I assisted at two scrotal infusion scenes. "Body modification - saline injection" now features on many BDSM checklists. You'll find infusion techniques turning up in books (there were labia and scrotal infusion scenes in Warren Ellis' book "Crooked Little Vein" ... "probably the scene I receive most email about", writes Ellis) and educational workshops (like Marc Paquet-Decker's "Scrotal Infusions (saline)"). I've also noticed several professional Dominants adding "saline infusions / injections" to their play specialty lists - Sydney based Miss Fleur de Lys recently blogged about an evening with a Doctor friend where the topic was 'How to Win Friends and Influence People Using Saline Injections': "very handy for those with a medical fetish and/or lovers of CBT and pussy play. I am very excited to have learned this new skill, it's been on my list of things to do forever!"

So saline infusions are definitely becoming more common. However, the regular reader I quote above is also right in saying that watching such scenes can be intense and confronting for new kinksters. That's understandable. This type of play is definitely edgeplay and definitely for advanced players. But it might make you feel better to read the quote below, from Donna's Life, the Universe and Donna blog, where an experienced kinkster comes face to face with her first labia saline injection scene:

"I am also rather amused to find that there’s still some things in kink that make me go “oh my god, ew! are you kidding me? people do that for FUN?” I was under the impression that even if I haven’t tried “everything” I had at least been exposed to just about everything. Nope! This one was new: Labia saline injections. The concept seems safe enough (the body will just absorb the saline pretty quickly, but leaves things … er, rather painful for a while afterward) but holy shit, NO FREAKING WAY is anything like that going near my hoohaw.

"Your kink ain’t my kink but your kink’s okay… over there. I lie, actually — I was totally fascinated to the point of wanting to apologize to the poor girl getting salined up for staring at her hoohaw for a good ten minutes straight, but seriously! THINGS ARE BEING INJECTED IN THERE, how could I NOT stare? Crazy. I am so not doing that. Hell, I won’t even get pierced down there…"

So you see, it's not just newbies who react a bit when they encounter these scenes *grin*.

You will find a lot of discussion online about how dangerous saline infusions can be and how no-one should do it. And you should read some of those discussions. But if as a newbie, the topic interests you - and let's be honest, it DOES interest a lot of men in particular - you'll find this post and it's References / Online Resources list, helpful.


This type of medical play - which is also sometimes called inflation play - is a temporary form of body modification where usually saline (a sterile mixture of pure salt and water - not to be confused with contact lens saline) is injected into the scrotum, labia or breasts. Sometimes other compounds are used for scrotal infusions, we will talk about that later.

The result is increased sensation and swelling. In the case of scrotal infusions we are talking serious swellings: "How big? Think softball, grapefruit, and, in one scene I saw, cantaloupe". Because saline is compatible with the body, the swelling decreases over several hours or days as the saline is absorbed by the tissues.

If this interests you, you might also like to google the following related terms: Saline Injection; Saline Injection Temporary Breast Enlargement; Saline Labial Injections; Scrotal Infusion; Catheter Play


"People who want to combine "saline" and "scrotum"
by means of an "injection" should feel free to replace
with "sulfuric acid"... such persons should
probably not
reproduce, nor be allowed within
1000 feet of a school or playground"

Ellison on a bondage.com thread

As Fleur de Lys observed, it's popular amongst kinksters with a "medical fetish and/or lovers of CBT and pussy play" as well as kinksters interested in inflation, and also ball stretching and pumping.

The "why do it?" question is often asked on forums where this type of play is discussed as too dangerous or just ridiculed. Not so much the saline breast injection or the medical play discussion threads, these often feature excellent responses. It's primarily the people who ask questions about scrotal infusions who come under attack.

I remember one poor bastard on bondage.com was ridiculed for five entire pages before the moderator shut the thread, just for asking in a newbie arrogant manner for information so he could attempt a scrotal infusion safely. Negative responses like "normal sized balls are good enough too. just a thought" are common on these threads. Worse, in one case on this particular thread one poster suggested the OP "try replacing the saline with air, and your balls with a major artery or vein. Its really kinky". That one comment was his entire post. It would probably have killed the OP if he had taken this advice.

Smart flippant remarks are all very well but on an open forum where a newbie with little experience asks for help, this kind of hostile, sarcastic and potentially lethal response is beyond appalling. So why are there so many threads like this?

In part because I think this kink is more misunderstood than most. Take the "your balls are fine the size they are" type response. Here's another from that same thread, where one poster did some "research" on scrotal infusion sites and found, in response to the "why do it" question that "the patient person felt as though his scrotum was too small somehow. I suppose it's the same type of mentality that makes some women get outrageously large breast implants". Note that: "patient person", rather than accepting that those interested in scrotal infusions are kinksters too.

Sure in some cases it might be the same mentality. But body modification fetishes focused on enlarging or stretching the scrotum (both permanently and temporarily) have been around a very long time, and are widely accepted. Genesis P. Orridge talked about someone who stretched his scrotum to his knees in Modern Primitives. Certainly someone interested in ball stretching / pumping would find scrotal infusions a turn on.

But there are other reasons for doing infusion play. The main one is because it's an intense form of sensation play. Let me paraphrase Anita- from Fetlife here, because I think she puts it best.

From the top's point of view there is a tremendous feeling of power and control, of temporarily changing the shape of your play partner. I can verify this feeling, in the scenes I did with bratty and cowboy - I really enjoyed the psychological aspects of playing a role in altering my friends' bodies, creating a situation that placed them in a constant state of genital awareness. You can also have amazing fun playing with the soft, heavy, enlarged body parts, which are incredibly sensitive.

From the bottom's point of view, Anita- makes these points:
  • Saline infusion involves extreme submission - to trust and give your body to the Top for modification (on the other hand saline infusion is a temporary body modification, you don’t have to commit long term changes)
  • Saline infusion has a tremendous humiliation factor
  • Saline infusion is highly erotic
  • Saline infusion provides intense sensations—big heavy balls pulling downward, big bouncy breasts, tight skin makes everything more sensitive, fun to play with!
  • Saline infusion is a form of self bondage, being held hostage by your own body
With scrotal infusion there is also the psychological aspect of some men who enjoy the weight and pressure on their balls (as this puppy play kinkster noted "It seems odd but when you're on all four paws, having a big heavy set of puppy balls swinging against your legs, it really puts you into the puppy mindset"), while others get off on the look of having really big balls.

This is one of the things where making things as close
sterile as possible makes a huge difference"
From a tribe medplay thread

"Some people would do anything to win a Darwin Award"
Body Inflation Forum

You do it very fucking carefully.

As I've already mentioned, you will find a million posts online telling you its dangerous and to leave scrotal infusion in particular, well alone. And you will also find horror stories of where things went wrong. However a great many of the horror stories are written by men - or by doctors ( see A Complication of an Unusual Sexual Practice by Jeffrey A. Summers, MD 2003) - who tried to inflate their own scrotum. Like this idiot Michael:
"I was very stupid and very lucky years ago when I had a very strong desire to inflate my scrotum. I cut a slit in my scrotum skin and used a bike pump needle used for airing up baskets balls,etc and rubber tubbing and ran distilled water into it and into my scrotum. Ouch… It ran in too fast and caused such pain I was sweating awhole lot. my scrotum swelled some from the water. I paniced some and squeezed my sac trying to squeeze the water out of the cut slit. All I know after placing a bandaid over the slit I went to sleep. Never tried it again. Learned my lesson. Was very lucky I did not do any damage to my reproductive system and did not get any infections"
What did he learn from this experience:
"Never try anything that you do not know much about. Study and ask lots of questions from experienced people that have done what your interested in trying".
Wise wise words, those. You might like to read them again!

The trick to this particular play is to have the infusion done by either a medical professional, or be trained yourself by a medical professional, like Fleur de Lys:
"[The Doctor] went through all the safety aspects while I listened attentively and took notes and asked questions. Then it was time to try it. She supervised as I injected 5ml of saline into each of my labia. The results really were instant and interesting, and my body absorbed the saline after an hour or so. I'm a big believer in testing out new things on myself first so I know how it feels and how to apply it"
Your last option is to be trained by someone who has been trained in this specific technique, but I'd prefer to get my training direct from the medical professional. Dr Dick of Dr Dick's Sex Advice column backs this up in his own description of doing a scrotal infusion, where mid way he comments:
"The infusion bag needs to be hung approximately three and a half feet, or one meter, higher than his nuts. You’ll need to know how to set up the infusion apparatus and bleed the infusion tube of air. If you don’t know how to do this, then you are in over your head. Don’t attempt this on your own."
I can certainly confirm that with someone experienced or with medical background in charge, infusion scenes become fascinating to watch as well as take part in. I love asking kinksters who do infusions their tips and secrets. Emma writes:

"injecting in four quadrants of the breast and through the nipple can be quite stimulating and with care more than 500ml can be injected into each breast ... it's almost impossible to fully 'rope a male breast as there simply isn't enough tissue there but above and below then cinching the two ropes in will help especially immediately after pumping. the fluid will be retained a little longer if the ropes are done effectively"

Here are some of Anita's tips:

"infusion for scrotal sac and breasts--slow and easy, a nice slow expansion that doesn't hurt the person too much.

"injection for labia--fast and painful, but necessary because the labia is very porous and the saline will reabsorb too quickly with an infusion. I hate doing labial injections however because I hate hurting women. But I will if they insist.

"don't do injections for breasts and sacs, you wind up with many holes and injection sites, lumpy bumpy odd shaped body parts, ick--infusion is wonderful (smiles)"


Here is one man's saline scrotal infusion story:
"I've had this done twice so far. Once with 500cc and the second time with a full litre. From my point of view it was partly curiosity to 'see what it felt like' and partly the submissive side of me wanting to give someone control to perform a possibly uncomfortable and certainly potentially dangerous procedure on a particularly sensitive part of my anatomy.

"What was it like? Very interesting and a little nerve racking once I was in position and waiting for the needle. As usual the sensation was less uncomfortable than I had anticipated and the infusion itself was almost totally free of sensation, apart from the tightening sensation as my scrotum started to swell.

"It was amazing to have all that weight swinging between my legs for a day or so. The first infusion took about 36 hours to be completely reabsorbed and the larger infusion was gone in two days.

"Would I have it done again? You bet I will"

Re breast / labia infusions, Kinkybitch1922 writes:

"For what it's worth, I've been injecting/having my breasts/labia injected with large amounts of saline for several years now with no ill affects. The most I've ever had in one boob was 720ml, more felt a bit "too much" pressure and weight wise"

fembottom49 writes:

"I was a demo bottom for a saline injection workshop recently. The injections were in the inner labia and clit hood. They were very stingy going in, I mean REALLY stingy but felt great afterwards. Increased sensitivity to any light touch. The demonstrator did one injection in the clit hood and two each in the labia. She specifically did not recommend breast injection because she said that they tend to make the breasts lose their shape and firmness. Some may disagree and I don't really know from personal experience.

"She also did a scrotum injection which was done with an IV line, and one of the bottoms got huge....like large grapefruit size. He seemed pretty pleased with how it felt..."


A quick glance at bzine's pages on this subject show a variety of non saline materials used for scrotal infusion, from air to KY jelly. Probably the most successful non saline substance is argon gas. One practitioner, BME founder Shannon, notes:
"normally in gaseous inflations CO2 or O2 is used, or sometimes just air, but that feels terrible when your body absorbs it for most people). Inflations like this are fascinating to watch (or do) because they’re just so fast in comparison to saline inflation — start to finish times are measured in seconds and minutes rather than hours."
You can see one of his photos of argon gas inflation above. You'll find some Nitrous Oxide inflation photos here, and you can read about a first Nitrous Oxide scrotal inflation here.


Some men do. In fact you can even buy online kits for self scrotal inflation. And find advise online on how to proceed. But guess what, I'm not going to go there. There are plenty of kinksters with experience willing to help you, if you desire to proceed.


I'm now going to write about a couple of scrotal infusion scenes where I assisted, to give you an idea of what the scenes are like, and how the procedures occur. This way, when you see infusion scenes at parties you'll know what's happening and they won't appear so confronting.

The first scene will also give you an idea of the kind of scene you'd experience yourself, if you want to try a scrotal infusion.


This scene was to celebrate Kittens-bratty-one's 50th birthday (it was a terrific party ... you can read more here). His owner MistressKitten had organized his first scrotal infusion as a gift. However in other cases where the sub is less well known to the dominant, Anita- suggests a few things to keep in mind prior to play:

  • Know your “victim”: How does his/her anatomy measure up?
  • Any Health issues —blood pressure, edema, diabetes, back problems, allergies to iodine or latex?
  • Any emotional issues —fear of needles, ready to be in saline bondage for over 24 hours, what is he/she looking for?
Rastas was the First Aid Officer the night of Bratty's birthday party, and performed Bratty's infusion. I was Dungeon Monitor for the night, and assisted in a minor capacity. As it was my first scrotal infusion Rastas kindly talked me through the procedure.

We placed Bratty on a medical gurney in a leather straight jacket. This left his legs and genitals bare. Alcohol wipes, latex gloves, bandaids, medical tape and a sharps container were placed between his legs.

While we snapped on latex gloves, Rastas explained how the saline solution had required heating to around body temperature. Saline solution being a gravity fed system, he hung the bag / drip tubing etc on an IV stand:

Some saline had already been squeezed into the vial - it is vital no air or air bubbles remain in the drip tubing. A small area of bratty's ballsac was wiped with an alcohol swip. Then Rastas inserted the catheter needle into the scrotal cavity:

The danger here is hitting a testicle. As one kinky instruction manual puts it "Unusual sensation if you hit the testicle itself….sort of OUCH…..ride the wave and enjoy extreme needle play".

The needle was then removed, leaving the teflon sheath in Bratty's sac. I handed Rastas the medical tape and he taped the tubing down so that it didn’t pull out or kink up. He connected the drip tubing from the saline bag to the catheter sheath, then adjusted the clamping device, allowing an even drip to begin to flow in the vial. Bratty felt tingling as the saline began to enter his scrotum.

As it was Bratty's first time Rastas only infused 500ml. Here is MistressKitten measuring the impressive result:

A litre next time, Rastas told Bratty!

It took about 20 minutes for the liquid to slowly drip it's way into Bratty. During the wait Rastas told me he prefers infusions to injections because the latter can end up with a lumpy effect. We also discussed the largest scrotal and breast infusions we'd seen.

When the 500ml was in, Rastas disconnected the saline bag and withdrew the catheter sheath, disposing of it in the sharps container. There was only a tiny spot of blood:

Bratty was pretty amazed with the result. Here Mistress Kitten wishes him Happy Birthday:

Here he is taking his first walk:

And finally here is my favorite photo of the scene, which I took when Rastas held a torch to Bratty's balls:

Everything went perfectly with Bratty's first saline scrotal infusion, and if this is something you want to try you could not have had a better experience. However Anita- provides a list of things that might go wrong, and what to do:

What can go wrong:

  • Hitting the testes with the needle--no excuse for this since you insert between the testes.
  • Victim gets faint or lightheaded
  • scrotal cellulitis-- If you make sure that you use aseptic technique, keep the needle/saline sterile, then this should not happen. But if it does, then it is easily treated with antibiotics.
  • Bruising, sweating--this may happen based upon the fragility of the skin of the person.
  • Leaking--use liquid bandage (or a dot of superglue) to seal the hole
  • catheter kinks up--this can happen if you are not careful to keep the person still
  • catheter breaks off--very, very unlikely

What to do make it feel better:

make sure the saline is VERY warm, almost hot; put a hot cloth on the infusion area and replace it when it gets cool; distract the victim to pass the time pleasantly.

Thank you to Rastas, Mistress Kitten and Bratty for allowing me to assist and write about the scene :) (sorry it's taken so long to publish the damn article, I asked permission way back at Bratty's party LOL)

The next infusion scene I assisted with was a scrotal infusion by injection:



This scene occurred at the same party. The players were ED, an experienced Dom I am just getting to know, and Devilwoman and Cowboy, my favorite extreme play partners :). It's always an honour to play with these guys. You can read about other scenes I have done with Devilwoman and Cowboy, and about this scene in detail, on my Edgeplay blog (if you want access to this blog, drop me a line below or via Fetlife).

Unlike Bratty, who was a scrotum infusion virgin, Cowboy had experienced lots of infusion play. Therefore the scrotum saline injections were not the focus of the entire scene, but only a component of it. Devilwoman told me she had negotiated a scene that included scrotal injections followed by knife, sparkler and branding play. It was certainly going to be a lot of fun.

Devilwoman had Cowboy anesthetize the center of the cock just prior to play commencing. We then stripped Cowboy off and placed him on the same gurney Bratty had used earlier.

Alcohol wipes, latex gloves, bandaids, medical tape and the sharps container were again placed on the gurney. This time however, the bag of saline was also placed there, rather than on the IV, with each syringe filled from the bag.

We tied up Cowboy's balls tightly with my favorite CBT cord, to stop the saline from escaping the scrotum. Then ED and Devilwoman began to inject 500mls of saline:

Cowboy's brightly colored and heavily decorated balls looked fantastic as the saline enlarged his scrotum:

Here is the end result:

At this point we removed my bondage cord and let his scrotum settle and spread a moment, before introducing a series of extremely sharp objects into Cowboy's dragon:

We then moved on to sparkler play:

The scene then became serious edgeplay, so I won't continue here. But in terms of infusions it was interesting to see injections into the scrotum as opposed to the saline drip. Thank you again to ED, Devilwoman and Cowboy for letting me share this scene with you.


Enough from me for today. I hope reading this post makes watching your next saline scene at a party more comfortable, and has helped fill in some facts if this is a technique you want to try.

If you want more info it's time to check out some of the online resources listed below. There are quite a few videos you can watch on YouTube, and lots of forums where you can discuss the topic. Have fun ... and good luck in your explorations!
