Ever since I discovered the fact that the testicles withdraw themselves up into the scrotal cavity when close to ejaculation, a fantasy came about and I have actually discussed it with my Mistress during our cbt play.
The fantasy goes that I am a strapped down naked onto the operating table and the female nurse instructs a group of schoolgirls in to examine and discuss the male genitalia. I am gagged so I cannot speak and I am firmly strapped down. The girls take great delight in looking and staring at my penis and testicles, the nurse grips my erectpenis, peels the foreskin right back tight so to show the girls the structure of the penis, discussing the shape of the glans, the groove, the meatus, frenum etc. She allows the girls to fondle my penis, maybe their fingernails accidentally - or not - scratch the glans, let them feel and pull on the frenulum, maybe pulling it too far out, this makes the girls giggle and laugh at me. The nurse reminds the girls about the purpose of the testicles, to make sperm, and to remind them again, how to recognise when the male is about to ejaculate when the testicles withdraw. The operation today is to expose the testicles upon ejaculation to see the inner workings. A small needle is injected into the scrotum to numb the sack, she carefully cuts around the base of the scrotum under the wide open eyes of the girls. As she cuts, there is a little blood, but not much, carefully the scrotum is removed so to expose the two testicles hanging down on the vas deferens. The nurse moves back my erect penis so to let the girls feel and explore the naked testicles. They take turns in feeling the epididymus and the general shape of each testicle. They laugh and giggle at the sight that one is smaller than the other, they take turns in squeezing each testicle. My screams are muffled by the gag as they scratch and squick each testicle with their young fingers. The nurse, after a while, tells the girls to be gentle with me as they might hurt me. The show stats by the nurse masturbating me, working my foreskin rapidly over my bulging glans, back and forth, the girls stare as the exposed testicles churn and turn, and as I start to near my climax, they observe how the testicles start to retract, the nurse thentells two of the girls to grip a testicle each and pull them out. As the nurse continues to masturbate me, the girls have to struggle by pulling harder on the testicles to stop them from disappearing, suddenly, the nurse jerks back my foreskin and I ejaculate, squirting sperm, the girls keep pulling the naked testicles out, stretching them to snapping point. As the sperm just turns to a dribble, the nurse instructs the girls to let go of the testicles, which are now drying out in the exposed air.They watch, holding in their giggles as my penis slowly pumps out a further dry orgasm. They watch as the nurse gently wipes each testicle with a moisturising fluid, attaches the scrotum and stitches me up until the next time.
More fantasies to come!
