I just nodded, not showing the fear I was stricken with on my expression. My fear of needles was always prominent from my very first injection as a toddler and I dreaded ever receiving vaccinations for anything. My eyes traced Miss Jones's every move as she lifted up the dreaded needle and flicked the syringe with her gloved finger before she lowered it and I felt the acute sting of the needle as it entered my glute muscle. I couldn't help but hiss at the sudden intrusion of my skin. The sting was heightened by the feeling of an alcohol-covered cotton ball being applied to the site of the injection for a few seconds, but the pain soon stopped and Miss Jones took the cotton ball from my skin.
Almost immediately I felt a fizzing sensation moving from my buttocks up to my groin and my cock jumped at the lovely tingle produced by this strange liquid that now resided inside of me. As I settled down, Chelsea and Hayley applied gloved hands to my chest and started to massage my chest again, my nipples once again standing erect at their lovely touch.
Miss Jones squirted three large globs of lubricant onto her right index finger and middle finger, stroking up and down these fingers with her left hand in order to spread it across the nitrile. She spread lube around my anus in a circular motion using her left hand, as my sphincter started to relax thanks to her delicate and professional caressing of my outer anal ring.
Amira Harding took the lubricant bottle from Miss Jones, squirting a generous amount onto her right hand and stroking up and down my erect shaft with her bare right hand. The pretty teacher retracted my foreskin gently and I moaned at the amazing sensation it created. Moments later, Miss Jones's cold middle finger quickly entered my rear and swiftly found its way to my prostate gland, which she massaged with a relaxing come hither motion of her long middle finger. A gasp for air escaped the red ball gag in my mouth as a second finger joined the first.
The feeling of Miss Harding's bare hand slowly stroking my fully erect penis added to the arousing torture they were conducting on my body. My toes curled as she started to tease my exposed glans with her other hand's index finger. Chelsea started to flick my erect nipple and Hayley soon started to do the same, making me grunt viciously through my gag as I started to feel close to ejaculating. However, the cruel injection that was tickling my crotch stopped me from doing so, a feeling I hated and loved.
I watched as Chelsea briefly stopped flicking my nipple and reached behind her, turning back around holding two strange pads that had white wires running from each. She handed Hayley one of the pads and they applied them simultaneously to my nipples. At the flick of a switch, a sudden surge of electricity hit my nipples and echoed through my body. The feeling it produced was exquisite, similar to the cold steel dildo that was in my rectum earlier. Constant small shocks from the pads on my chest enhanced the amazing stimulation being given to me by Miss Jones and Miss Amira Harding.
My body squirmed and I tried to ejaculate as best I could, but the peculiar injection continued to deny me the sweet release of my orgasm. Miss Jones removed her fingers from my rectum and a relieved sigh was muffled by the large ball gag that sat uncomfortably in my mouth. I wasn't free from the intense sensations in my behind for long though, as I felt a cold object teasing the entrance to my hungry hole. After circling my bottom with the phallic object for a few moments, Miss Jones quickly popped the instrument into me and it slid easily into my tight sphincter. My eyes started to tear up as my arousing torture dragged on, my body desperately needed release but no matter how hard I tried, I continued being denied.
Soon the electric pulses being delivered ruthlessly to my nipples became more intense and more constant. I fought my bonds as hard I could, but there was no way I could escape them. Miss Harding's seductive smile broadened as a bit of precum dribbled from my exposed glans. Her strokes started to vary in pace. Three fast, two slow, four fast, five slow. The feeling it produced drove me mad as muffled screams erupted from my mouth, now filled up with my own saliva. My eyes rolled back in my head as Miss Jones started to slowly move the object in my ass in a viciously arousing scissoring motion, in and out of my tight hole. As she did this, her other gloved hand seductively teased the skin in between my scrotum and bottom, adding to the amazing tingling sensation being produced by the injection from earlier.
Chloe Lovell was visible in the corner of my eye, smiling at me as she witnessed my humiliating and excruciating torture. I say this; I didn't hate nor even slightly dislike it. It was fucking hot, but my constant denial of cumming drove me absolutely insane. I turned my head to look back at the pretty nurse smiling at me, my eyes filling up with tears and nearly drowning in saliva. She was so beautiful, a flawless figure and a very pretty face. Her smile was so gentle and cute, her eyes caring and loving.
My attention was soon wrenched from the beautiful young woman on my left as my balls once again retracted and I felt my climax coming up. Miss Harding started to make her strokes more consistent as she picked up pace, Miss Jones quickly removed the cold object from inside me and replaced it with her original two fingers moving in the familiar come hither motion from moments earlier. Chelsea cranked up the electric pads on my nipples even higher and it produced the best sensations so far as I shook in my bonds. Miss Lisa Penley rushed to my side, holding a large plastic test tube which was similar to the one used to take my urine sample earlier.
"I want a nice big load now, George," Miss Jones said, her fingers deep inside me.
Miss Lisa Penley placed the test tube over my glans and Miss Harding increased her stroking pace even more, as her hand that was on my head started to play with my scrotum once again. A large surge of electricity made me jump in the table and I felt very relieved as I passed the "point of no return" and I felt my semen rushing up through my erect shaft before my new best climax ever hit me and I ejaculated seven large globs of cum into the plastic test tube, each spurt producing a loud yet muffled moan from my gagged mouth. Miss Harding let go of my cock as Miss Penley took over, emptying me out as Miss Jones pressed down hard on my prostate to lengthen my climax. The intense electrical currents pulsing through my chest were soon weakened before they completely stopped and Miss Jones retracted her two fingers from my rectum. My cock was fully emptied out into the tube and Miss Lisa Penley took the tube from my shaft, holding it up above her to inspect the nearly full container.
"Seven millilitres," she remarked, walking off to the counter to deposit the tube into a rack. "Very impressive."
