My girlfriend and doctor turn me into a sissy

Sorry if this is super long. Also let me know if you like to read a part 2.

********

As the coronavirus pandemic started last year, most offices including mine and my girlfriend’s went to a work from home model. The day this was announced I decided to travel to my girlfriends’ city and live with her till the end of the pandemic since we were doing long distance for quite sometime and this would a great opportunity to live together for an extended period. She was equally excited when I proposed this and as soon as the lockdown started I quickly grabbed a small bag of clothes and started my 8 hour drive.
Once there my gf was super happy to see me and after a quick shower and outright throwing away of all clothes I had worn on the drive, we threw ourselves on the bed and had passionate sex after a long time. Though I was way below average in size my girlfriend never complained or even brought it up and I tried to make up whatever I lacked in size by putting in the effort to make her happy.
A couple of days had passed and the suddenly developed a mild cough and a slight fever. We thought maybe I was coming down with the virus so I quarantined in a separate room, and ordered an at home test kit. The test kit arrived soon and I took the test and shipped it back but it came out to be negative. So I took another test and still it was negative. But the cough didn’t seem to go away. So my gf suggested going to the doctor to get checked out. However no doctors were taking new patients at the time, so I was stuck. Finally my girlfriend called up her primary care physician and though her specialty was women’s health she agreed to see me the next day.
The next day arrived and we started to get dressed, that’s when I realized I didn’t have any underwear. I had forgotten to pack my toothbrush and underwear in a hurry, though I could buy a toothbrush at a nearby gas station in middle of the night when it was almost empty I wasn’t that lucky with underwear. Since I was staying at home and going commando most of the time I just ordered some underwear on Amazon and unfortunately without prime shipping they hadn’t reached yet. When I told my girlfriend, she nonchalantly said “wear a pair of my panties. It’s not that anyone will know”. For the lack of a better option, I agreed. She opened her lingerie drawer and said “knock yourself out” and walked out of the room. Most of her panties were super feminine and more importantly thong styled. I rummaged through and found one which appeared have the most coverage. I slipped it on and my gf walked in. She immediately chuckled and said “nice choice, the bright pink surely makes your butt look cute. And the fit seems perfect”. I blushed but she was right, the panties did fit me perfectly with my 27 inch waist and my rather small thing. She quickly took out her phone and snapped a pic and said “one for the memories”.
I quickly got dressed after that and we hopped into the car and rushed to the appointment. The doctors’ private office was neatly decorated and thankfully there was only one patient before us. It was a short wait will I filled up some forms about my medical history and soon I got called in and my girlfriend accompanied me inside. Dr. Sonia seemed really nice, she exchanged greeting with me and my gf and quickly did her exam and said most probably it is the common cold and nothing to worry about. As we were about to be done she said “have you had your routine physical this year”, I replied “no”. Honestly I hated doctors’ offices, I had rarely ever gone for a routine physical. She sighed and said “ I doubt the pandemic would be over anytime soon so while you are here let’s get your full physical done for the year.” I was about to say no when my girlfriend interjected and said “just do it, we are in no hurry”. I shot her a look but couldn’t say anything. So the nurse came in and walked me to a different room for the exam and handed me a hospital gown- “ please strip down to your underwear and put this on, the doctor will see you shortly” and walked out. This didn’t turn out as I expected, as I started to strip I just prayed that the doctor would either miss my underwear or wouldn’t mention it at all. Just as I put my gown on I heard the door open, I wasn’t facing the door but I quickly turned. Dr. Sonia had a grin on her face and asked “ whose underwear are those? They look really cute on you”. I said they are Priya’s (my gf) and tried to explain the situation. She cut me short and said “ I hope you don’t mind if call Priya in?” and yelled out for her. She walked in with a huge smile on her face and instantly asked Dr. Sonia, “ doesn’t the panties look super cute on him?” and they bother laughed heartily. I also smiled along with them hoping this will be over soon. The doctor started with the physical exam and lastly arrived at my privates and said “can you lower your PANTIES a little?”. I did as I was told and my little thing popped out and Dr. Sonia stared at it long and hard. I instinctively asked “is there something wrong doctor?”
She replied “ now I know why the panties fit so well. Looks like you may have a condition called a micropenis. We have to measure you both flaccid and erect to be sure. Let me bring my tape”. She quickly brought her tape and measure my flaccid length, then she went “can you try to make it erect now?” I really didn’t know how and I closed my eyes and tried to think of things that made me horny but I just couldn’t under the specific circumstances. “Priya why don’t you help him a little, I will look the other way” remarked Dr. Sonia. So Priya tried to give me sort of a handjob for about 30 seconds but nothing happened. I didn’t think I could get hard being at the current situation. Dr Sonia understood it and said “don’t worry, if you want we do have other methods”. I figured it must be a pill or an injection and quickly responded “let’s try that”. She responded “great, can you quickly lie down on the examination bed”. I did as I was told and then Dr. Sonia brought the stirrups closer and instructed “legs up on these please”. I immediately reacted “what? Why?”. Then she explained it wasn’t a pill or injection she needed to access and massage my prostate and that was supposed to give me an erection. My gf was still trying to control her laughter remarked “ hold my hand and just close your eyes”. As I did that I felt something cold near my asshole, I guessed it was lube. Then a single finger abruptly went in and lubed up my insides and then came out. I momentarily thought my humiliating ordeal was over and I opened my eyes to see an device I had never seen before, I shrieked “what the hell is that?”, my gf now laughing held my hand and said “ it’s a speculum sweety, don’t worry you’ll soon know what it does”. The speculum went in smoothly up my lubed ass and then I felt like someone was tearing me apart. I could feel my hole widening and after what seemed like an eternity the widening stopped. I could still feel that I was spread apart, Dr. Sonia said “I think this is enough” and this time just asked my gf “I will massage his prostate while someone needs to measure him. Do you mind if we call the nurse in?” She blurted “sure thing” and yelled out for the nurse. The nurse came in and almost burst out laughing and followed the instructions was ready to measure me. Dr. Sonia inserted 3 fingers and started to massage my prostate. Within a couple of seconds I forgot the situation I was in and overwhelmed by pleasure I let out a quiet moan. All 3 women laughed out. “Seems like he is loving it”. I could feel I was fully erect now and the nurse measured me. It was 3.4 inches. Then as the doctor was about to take her fingers out my gf said “this is definitely one for the memories book. Do you ladies mind if take quick pic”, obviously they had no problems and my ordeal was immortalized. After the speculum was out Dr. Sonia explained that the reason for my micropenis could be multiple so she had the nurse draw some blood for testing and then explained she needs to test my semen as well after 2 weeks to see sperm count and motility. She then said “but till that time you guys cannot have sex.” My girlfriend replied “I can make sure of that but what I cannot make sure of is him not masterbating”. Dr. Sonia said no problem at all and instructed me to go lie on the table and put my legs up like before. I was beyond the point of resisting now so I did as I was told. And as I laid down I could see the ladies talking about something. Finally after a couple of mins they came to me and said “so you’ll be wearing this chastity cage for the next 2 weeks to stop masterbation. Your gf picked out this cute pink color to go with your panties. Hope you like it. But firstly before you are fitted with it I will ask the nurse to shave all around otherwise the cage will pull on the hairs and make it more uncomfortable”. She went out and returned with the nurse and all shaving equipment and this time my gf started recording a video. She asked the nurse “would it be possible to leave a nice landing strip” to which the nurse smiled and nodded. Priya turned to me and said “now we will have similar styles” and the nurse was soon done and the Dr. Sonia placed herself between my legs and slowly fitted the cage and said “ this should work just fine” and my gf remarked “ Ohh it’s so awesome, I guess a good side effect will be he won’t be able to stand and pee and that’ll keep my restroom free from splashes of pee.” Dr. Sonia chuckled and said also remember to wipe after you pee, we don’t want infections. After that I slowly got dressed and after paying the dues at the front desk we left with me wearing a chastity cage and panties underneath my clothes. I was struggling to wrap me head around what had happened but my girlfriend seemed to have enjoyed my predicament. Who knows what awaits in the next 2 weeks.
