A cuckold education

"Do you mind?"

"Help yourself, you come highly recommended" and Helen hands Diana the key to my cock cage.

"Where are you up to in his training?"

"This is his first time in more than panties. He knowingly became a cuckold for the first time just the other night" Helen beaming with pride at her achievements. A deep sense of humiliation sweeping over me, I feel my cheeks blush and my cock harden in its cage. The pain is already starting, and although I don't know why there is no denying the humiliation turns me on - I accept this, feeling helpless in the presence of these strong women.

"And you brought her here straight away. I am honoured! You are well informed - what are your goals for him?" Helen leant in and whispered into Diana's ear something I din't hear. "Ah, excellent. I am sure I can assist with that"

Diana approaches me with a wicked smile, and a lustful look. "I am going to play with you sissy. If you resist or disobey a single one of my rules, I will throw you out in the street as you are. You will be arrested by the police as a pervert and will be lucky not to be gang **** by the end of the day. You are not allowed to talk in this shop, ever! Do you understand?" A nod.

"As you train him, it's important to continuously break down his ego, and condition his responses." Train me? I didn't sign up for this!

Diana reaches outside the cubicle and grabs something. I see rope, which she wraps round my neck and then uses as a leash to control me. She uses it to back me up to the wall. I look over at Helen and she is watching, eyes wide in anticipation. Diana leans in close and she kisses me! I open my mouth and her tongue darts in. I am overwhelmed by the simple sensation of this goddess's kiss. As her tongue withdraws my tongue follows it past her teeth into her mouth. She bites my tongue, enough to hold it, but not enough to cause (too much) pain. I still. "Shhh sissy. Enjoy..." She breathes into my mouth as I become aware of her other hand, touching my ass, sliding inside my panties and then I feel a cold wet object against my asshole. I try to move to avoid it but between my captured tongue, the leash on my neck, and her hips holding me in place I have no where to go. She pushes in, I whimper "There, there, take it" pushing hard, I am opening, hurting, burning, a lot, and then it is in. I feel relief. Her teeth releases my tongue "Good girl, Kneel"

Once kneeling she ties my rope to a bar at the edge of the dressing room, and turns to Helen "Now we can begin"

I see Helen lick her lips in anticipation as Diana starts a slow striptease in front of her. I obviously see it from the back, the reveal of her, shoulders, of her ass as her skirt is lowered and then her glorious legs. My wife gasps and I see Helen's eyes go wide like saucers staring at Diana. "You like that do you?" A nod, and then Diana turns to show me her secret. Diana turns to show me.

Between her legs is a cock, much larger than mine even soft "It is your duty cuck to get this hard so I can fuck your wife. She pushes it into my mouth. I am in awe of this beautiful woman having a cock, and despite never having considered cocks attractive, I suck eagerly. "See Helen, he's a natural" Humiliation washing over me knowing that my wife is seeing me suck this cock so eagerly.

Sooner than I want her cock is hard and she approaches my wife, stunning in her basque and stockings, and pushes her up against the edge of the table in the fitting room. Helen opens her legs for Diana's cock and with a smooth thrust her full length is in. Helen gasps at the unaccustomed size "A big cock is so more satisfying isn't it dear"

"Oh God Yes" looking at me "Much better that a useless sissy cock" I am taken aback by the venom in her voice, but my cock is hard in its cage.

"Of course dear, you have started a very wise journey. And of course we must continue your Cuck's training... watch" and she presses a button on a black remote control in her hand. The plug in my ass starts to pulse in my ass directly onto me prostate and I yelp, jerking at the stimulation.

Diana proceeds to fuck my wife hard. Helen has completely surrendered to this superior cock and is panting in ecstasy as her pussy is pounded. Her eyes have rolled back in her head as she has a series of orgasms, shuddering violently with each one, eyes tightly closed. Diana is in turn watching me, smiling victoriously as she takes my wife, proving to me once and for all that I can't satisfy her, for it is obvious to both of us that Helen has never responded to my cock like this.

Just as she is about to come she presses the button on the remote and I cum inside my cage. But whilst Diana has a powerful orgasm in my wife's pussy, my orgasm dribbles out of the end of my cage, a ruined orgasm that provides me no satisfaction, just more frustration. I look helplessly at my useless cock, and then in shock at the two lovers to see my wife looking at the puddle of cum between my legs. "Oh my god, did your sissy cock just cum watching me get fucked."

"He's evolving. He's almost totally submissive now"

Diana's words echoed in my head and I knew that if I was to escape this fate I needed to man up, and soon, but did I have the willpower?
