Pain in the ass

As I looked around the room at the grinning women looking at my naked body, I first thought this wasn't so bad, except I was married and my mother in law was front and center!

"Turn him over, it'll be much faster that way." She said, looking at my crotch.

Two of the nursing students undid the sling my cast was in and they pulled my arm down onto the bed while two other nursing students grabbed my other arm, then the four of them proceeded to pull my arms to make me turn over. My ass was now in the air, my legs spread as my knees were on the bed, and they pushed on my back so my face was contacting the bed.

"Just relax and this will go much easier. Just imagine when you'll be begging for this while you are unable to use your own hands." I heard my mother in law almost chuckle with joy as she told me.

With my back being pressed down, I couldn't see what she was holding. But as soon as I felt something long, thin, and smooth enter my anus, I figured out what it was. Once it was in all the way, all the women applauded, and I just felt so embarrassed about everything up to this point. Part of me would have rather been **** for this, but it would just be delaying the inevitable. I had a prostate massager inside me. And my mother in law was holding the end of it. She twisted it around and gently moved it around. I felt my body betray me as my cock got harder and I felt a surge of warmth in my loins I never felt before.

I let out a couple involuntary moans as my mother in law pumped the massager in and out. With one arm immobilized and the other unable to snag or grab onto anything, I just lay there and took it. Until...

"EEEEUUURRRRRRGGGGGGGHHHHHH!!!"

I'm not even sure what tht noise was or how I made it, but apparently it's the noise I made when I had an orgasm from my prostate being stimulated.

The everyone cheered as the nursing students let go of me. I was able to lean back on my knees and saw the mess I made on the bed. After years of long and hard sessions, I thought I knew what I could produce. However, what lay on the bed in front of me seemed worthy of a pornstar (not to brag). As I was trying to understand what just happened, I got a tap on my shoulder.

"Turn to face the camera so we can document how you look and feel right now." The doctor ordered.

My mind was in a jaze as I turned around on the bed and looked down at my deflating member. I felt drained in more ways than one.

"Spectacular results! Less tan a minute and he ejaculated more than he would under normal conditions." A nursing student proclaimed.

"Wait, how do..." I tried to ask.

"We performed a few hands on experiences while you were ****. We had to get a baseline for the experiment. So far, heart rate is good, coherent thoughts seem to return fairly quickly. Now, one last test..." the doctor said.

As I knelt on the bed, still catching my breath, I saw the doctor stand in front of me and lean forward. She gently blew on my flaccid, still dripping penis. I gasped at the sensation. It felt like my cock was being rubbed by a cloud.

"Oh my! I hope he'll have more control as he adjusts..." my mother in law shouted.

If I had my strength back and fully cognizant, I would have shouted in surprise as well. That single gentle blow from the doctor had stimulated me enough to become erect almost immediately.

"Subject has a new erection within seconds of a gentle stimulus. His heart rate is nominal and blood pressure seems fine." A nursing student noted.

There I was, panting, soaked in sweat and with another hard-on that begged for release. I just hoped I wouldn't become too **** to cum anytime soon.

PHLOOPPP!

I was speechless as I felt a rather strange sensation in my ass when my mother in law forcibly removed the prostate massager from my ass.

"This is only for emergencies or to reward you for being good during your treatment." My mother in law said, holding the device to show me.

It was a purple tube that curved about 6 inches from the tip, to be a handle for the user or a partner, which was how my mother in law was brandishing it for the w9men in the room and the camera.

"Can I get dressed now?" I asked.
