Anna's Sub - Dr. Mistress?

I generally have a session with my mistress every weekend as we both are busy with work during the week, she does keep my occupied with small tasks throughout the week so that I do not slack off and remember who owns me.

But this time, I got a text from my mistress telling me to take the Wednesday of this week off from work and to meet her at her place on the morning of that day.

It is Monday today and I think to myself about what is going to happen on Wednesday.

I squeeze in the excitement and apply for a leave.

Finally the day comes, I dress up, tidy myself and leave for her house.

I reach there and she greets me with a grin on her face. It is the cutest a man can ever see. Seeing her made me even more excited.

I enter and see some towels, an antiseptic solution and a box of latex gloves neatly stacked on the table. I kneel down beside her chair as she goes in. After about 5 minutes she comes out, dress in a sexy latex nurse costume. This confirmed the thought that came to me. I am excited yet nervous as it will be the first time trying this.

She tells me to ease up and to sit comfortably on her chair. I get up and sit on her chair, she starts talking about how she watched a medical sitcom and now has the fantasy of medical domination. She talks about enemas, needle play, tens units, medical staples, speculums etc and asks for my consent (which I readily provide) She commands me to kneel back down again. She collars me and picks out a file from under the table with my name age and all sort of details in it.

"Shall we begin?" she excitedly asks.

I say an enthusiastic yes and we begin. She starts to put on some latex gloves while my thoughts began to race having no bounds and understanding as to where this will progress henceforth I was still lost in my thoughts when suddenly, I feel a tug on my collar. I snap back to reality. Shaking internally with excitement, I let go and yield to whatever is in store for me.

She guides me to the bathroom and commands me to get on my knees and hands. I do so, while I am on all fours, I thought of what could she be up to when I feel her toying with my ass. She rubs some antiseptic on my asshole and massages it sensually, she then inserts one finger and starts to wiggle it, Slowly I can feel a probe getting inserted in my ass.

"Enemas are very important for our patients, it makes sure that they have a clean ass for further examination!" she said this while maintaining a strict professional demeanor.

I clench my ass as a natural reflex, she coaxes me and pushes my butt cheeks apart with her hand while slowly and gently pushing in the probe further.

The probe is around 4 inches deep in me at this point and I start feeling the ooze of liquid in my ass. The sudden feeling of being full overcomes me and all my focus now is on holding in the liquid while clenching even harder on the probe.

It was a tease of pleasure and the tension of focus.

After she was satisfied with the enema, she hands me some towels and tells me to clean myself up. All the while she maintained a strict and a straight face as she was an actual nurse going about her day.

I had never seen this side of hers, she was totally different than her usual sadistic and strict demeanor.

She commanded me to lie down on my belly, she tied the other end of the leash to the head rest and cuffed my hands to the restraints she must've setup earlier under the bed.

"This is a mix of professionalism and kink," I thought to myself.

She puts a ball gag in my mouth and starts to finger my ass again. This time, I let out a small moan and she spanks my ass and shushes me.

"Sir, this is a hospital and we request our patients to not get sexually aroused here." she said this strictly while playing with the fact that she had just spanked me.

I was livid and turned on with her conduct.

She was in a different headspace today it seems, this was so fun and weirdly cute.

She is fingering my ass and exclaims -

"I will now be taking your temperature."

And proceeds to stick a thermometer up my ass, the metal bulb was cold and made me clench my ass again.

"Good, clench your ass so the thermometer does not come out."

She makes a "note" of my temperature and starts to finger me again, this time I try not to let out any sort of sound.

She slowly makes her way to my prostate. Starting with one finger, she inserts another one, then a third one until she was fisting me.

My asshole ached as it was being stretched, yet mommy had trained me anally good. Her wrist felt like a ball being shoved up my ass, my insides were stimulated with the constant feeling of skin brushing against it.

She starts to massage my prostate. I squirm as I get the instant urge to pee and wriggle under the restraints.

"Prostate seems in a good condition, are you up to date with your vaccines?"

I did not know what to reply to this.

She sits on my back and hold my ass down tightly -

"You need your daily shots!"

"Is she going to......" and I see her taking out some needles.

She rubs my ass with the alcohol wipe and pinches a thick portion of my skin and inserts the needle in my ass. It was painful but as a pain slut, it was enjoyable at the same time. She saw me clench my ass and says -

"Awwwww, did it hurt bitch?" I felt the sadistic tone coming back in her voice.

She takes another needle and pierces the other cheek. I have two needles sticking in my ass while she sits on my back and jiggles my ass.

I squirm and moan as the needles move causing me the sweet sweet pain that I crave.

"This is just the start my dear." She said this, even though I couldnt see her, I could feel she said this with a smirk. You could feel the naughtiness returning in her voice.

She takes another one out, "I thought to myself, how many did she buy." the previous two were lightly and carefully done, but this one? not so much, it was hard and abrupt as she jammed it right in the middle of my cheek in the fleshy party.

I lift up my head in pain and she reached back with her hand and pushed my head down.

"This is just one cheek!!!" she exclaimed as she let go of my head and jabs the other needle in the middle of the second cheek.

I was breathing heavily and could feel her body vibrate and shake as she laughed at me.

The thin needles made an excruciating pain when poked and then a dull damp pain when pushed in. She maid sure to push the needles deep in further so it reached the muscle and caused more pain. It felt so good. It felt like I was being punctured and my ass was overwhelmed with pain and pleasure.

"Spanking isn't the only way to cause you pain," she laughed as she said this.

I was aroused by her and intimated, what started off as a playful cheerful session was now a full sadistic session, my mistress was back to being who she really was and continued poking and jabbing different areas of my ass with her needles. Laughing and giggling after every prick.

With around 20 injection in my ass, any slight movement caused me pain. She had no plans to stop, She took out just the needles and lightly pierced the top layer of my skin, right in the middle of my butt cheek. It was painful but VERY arousing, my cock was hard and dripping with pre cum.

She pierced my butt cheek few more time with needles and left them there. She enjoyed the jabbing as she poked and prodded my ass cheeks with the needles. She finally got up, stood over me to admire her work. I could feel blood flow on my cheeks which she cleaned with a cotton gauze. She walked forward towards my face, positioned her pussy before me and pushed me down commanding me to lick while picking up her latex skirt. She was wearing black latex panties, the outline of her ass as it seamlessly merges with the latex was like looking at the horizon on a beautiful sunset. I was drooling and was mentally mush seeing her like this.

"My panties are not shiny enough, you better clean them and shine them with you tongue." She commanded while pulling on a flock of my hair.

I started to lick, any effort made into licking her panties made my body move and disturb the needles.

"She's a genius." I thought to myself as I was overwhelmed with pain and pleasure.

"Good," she chuckled.

"My panties better be shining, the latex was dull..... LICK IT, you've got to shine the backside as well." Her commanding voice and strict tone made me want to obey every single thing she tells me to do without and question. Her pleasure is all I crave for.

I lick and make sure every part is properly licked, she turns around and I do the same for her ass. Her plump ass is bounded by the tightly fit latex, a cruel guard gatekeeping her fleshy thick ass from me.

After she was happy with my work, she gets up and very carefully removes the needles one by one and safely disposes them off. She cleans my butt with some betadine, washes it and gives me a kiss.

"GOODBOY!" she exclaims, giving me a sense of fulfillment.

I thought this was the end of it but then she takes out the Speculum.

"You thought it was over huh," her tone reeking of sadism.

She spits on my ass, spanks it a few times. The spanks on the poked and prodded ass hurt even more than it normally does, even though they were light playful spanks. She inserts the speculum, its girthier than most of the dildos she has pegged me with. It pained but less than when she started to stretch my asshole. I groaned in pain letting out slight grunts. Each grunt of mine was met with a chuckle. She opened it and spread it to the part where my asshole was constantly under tension and was stretched. She disappeared for like a minute and came back with some ginger and just dropped them in.

It started to burn.

I wanted to clench my ass so bad but not being able to just showed how helpless I was which only turned me and my mistress on more. I slightly uttered some words that did not make sense because of the ball gag I was wearing. Mistress did not pay attention to it unless it was the safe word.

'Shall we turn this up a notch?" She asked.

I kept quit because I knew that my answer was not important but

She spanked me and asked me once more -

"Shall we turn this up a notch?" She screamed.

"Yes mistress" or something along the lines of it which I tried to mutter due to my gag.

She got out a TENS unit. She stuck 2 electrode, 1 on each cheek, 3rd one on the shaft of my penis, 4th one on the place between my balls and the asshole and a 5th one right below the speculum on my ass crack.

I was nervous and was not able to naturally react to any sort of stimuli on my bottom area as it was literally being stretched apart. The burn of the ginger had died down a bit but was still present.

I started to feel the small pulses of electricity zapping through. It was an overload of senses, pain, burning and pleasure all combined teleported me to an euphoric state.

She got up, removed her panties and stuffed them in my mouth. She sat on my back and started grinding herself on my back while increasing and decreasing the electricity. She enjoyed when my ass twitched every time she increase the current. There was a point where I sharply squeezed my ass because of the current passing, then suddenly dropped it when she stopped/lowered the electric current.

She toyed with my ass some more with it widely stretched and grinded herself to a couple of orgasms.

After she was done, she got up. Her demeanor quickly changed from sadistic to the loving mommy domme she usually is after sessions.

"How was it my baby boy?" she asked while removing the electrodes and the speculum.

I thanked her while muffled and she laughed as she forgot I had a ball gag on. She removed and carefully got me free of all restraints.

I let out a soft groan she got back on my back and started massaging my ass.

I laid there, pleased with myself for being able to please my mistress with a new fetish.
