A blacked femboy story

"Time to go home" - you think while sighing deeply. Looking through the front window of the cafe you work at you see the sky. It's a dreary gray. The clouds move quickly. “Looks pretty chilly” - you think to yourself.

Letting out another deep sigh you embrace yourself and step outside. Immediately caught by the chilled breeze, your little chastity cage turns cold, and your strained balls shrivel up. As you move out into the street, a stronger breeze blows from under you, forcing you to quickly grab the edges of your skirt to prevent it from lifting up.

You walk left and look back at the cafe you work at. It's a specialty cafe of sorts, one only for femboys like yourself. Another sigh... “What happened to you?” - whispers some voice within you. You push the interrogating thoughts away. No use for those anymore. You're in too deep at this point.

You cross the street and walk along the edge of the small park. You moved to this European city last year with your girlfriend - Natalie. She didn't want to live away from her bull, who moved here to cooperate on a new research paper with some peers.

The city is beautiful, the streets are clean and safe, and the people are kind. You pass a national museum on the right and an avenue with a statue in the middle on the left.

As you approach the bus stop, you can see a few people already waiting there. You try not to look at them too closely, feeling shy and not wanting to bring attention to yourself. The wind caresses your thighs and keeps playing with your skirt. You sense the gazes of a few guys turn toward your butt.

The bus arrives, and you step inside. It's not crowded, but there is only one free seat close to where you got on. You walk towards it but stop when you see a man heading for it as well. He notices you looking at him and smiles.

"You take it. I'm fine." - He says.

You open your mouth while looking up at him to say "Thank you" but end up saying nothing and just nodding in thanks. It's a single seat right beside a window. You bring your knees together. Your feet, clad in stylish women's chelsea boots, apart.

The bus leaves the stop, and you look outside. Instead of on the city, your eyes focus on your reflection. A slim build. Teenage looking face. The few remaining masculine features obscured by makeup. Blue eyes, shoulder-length dark hair, and, embarrassingly, a small but recognizable chest.

You blink and refocus your eyes, this time making sure you look outside and not at yourself. Your current appearance is 'thanks to' or 'the fault of' your girlfriend's black bull - Mason. He's a renowned scientist, a bio-engineer, and is rich, tall, muscular and has a huge cock. Natalie fell for him instantly after he took her from you at a bar and fucked her in a bathroom stall.

Mason's research has to do with youth. He's trying to develop a drug that would prevent or slow cell degradation and aging. One day, he presented you with papers for a medical trial. When you refused to sign the agreement that would let him experiment on your body free of charge or responsibility, your girlfriend threatened to break up with you. Not wanting to lose her, you acquiesced and signed everything.

The experiments worked. Despite being an average 24-year-old guy, your body looked younger after each dose until you seemed 18-19. The drug had some, at least to you, unforeseen side effects. You didn't just look younger. You became more and more like a cute young girl. You enjoyed the femboy aesthetic. You even fantasized about being one a few times, but actually having your body become thinner, weaker, and even shorter was scary.

Your body turning into a small, frail, and sensitive mess wasn't the only effect. Besides physical changes, the inner workings of your mind were affected as well. After a few months, you realized you behaved completely differently from you in the past. Looking like a girl, thinking like a girl, acting like a girl. If not for all the pills Mason feeds you to keep you sedated, you might have become very depressed after realizing there was no way for you to go back to your previous self.

The bus is getting close to your stop. You stand and grab onto a vertical handrail. From here, the walk home takes you just a minute.

You open the door to your place and take off your shoes, revealing petite feet in sheer, white socks. You can hear the shower running. Natalie is sitting at the table with another girl you don't recognize. They're just chatting.

"I'm home." - You announce meekly.

No reply. You turn to go to a different room and not disturb the girls' conversation. As you pass the bathroom, the door opens, and a large, black man walks out with a towel around his waist. Your eyes naturally wander to his crotch area, where the towel bulges out from his hanging, thick cock.

"Oh, good that you're here already." - He says, looking down at you. - "You're getting an injection today, so clean yourself up first." - He points at the shower with his thumb and grins.

Your little mind gets thrown for a spin. This doesn't seem right. You force yourself to stop looking at his cock and look up at Mason's face.

"Eh...? But it's only been two days since last time...?" - You reply.

"We're switching to daily doses. I want to see how your body reacts to that. Don't worry." - He reaches out his hand and pats your head gently. - "I'm already done with your girlfriend, so we'll have plenty of time for your 'reward' after the procedure." - He says with a devious smile.

Your mouth waters and you can feel yourself getting wet in your cage. Your mind, about to glitch and hang on the thought of the 'reward', gets brought back into reality by Mason's hand leaving the top of your head.

"Don't make me wait." - He says as he passes you and spanks your ass.

You throw your bag into a corner and hurry into the bathroom. You take off your blouse and bra and unpin your choker. Pull down your skirt and panties. After gently pulling off your socks to not damage the thin, delicate fabric, you put the clothes into the laundry basket.

Walking into the shower and turning around brings into view your girlfriend's black dildo collection displayed on a glass shelf. You get aroused and get an urge to use one. Your cage drips boy juice in excitement, but Mason will be mad if you take too much time.

You turn the tap and thoroughly cleanse yourself with warm water and soap. After drying your body, you reapply some light makeup. You have trouble deciding which lip gloss to use to make your mouth more inviting today.

Quietly leaving the bathroom, you head to the bedroom to dress yourself up. New and fresh lingerie and stockings. A matching choker. A naughty, semi-transparent, loose top. You look at yourself in the mirror and caress your body from top to bottom.

Having gotten ready, you shily walk over and stand in the doorway of the room that Mason and the two girls are in. Mason is lying down on a sofa with a glass of whisky. The unknown woman is by his side, kissing his neck and rubbing her body on his while your girlfriend is lovingly licking his magnificent balls.

He notices you and beckons you to come closer using his hand. You obey. Despite being in this situation many times before, you feel embarrassed. The women don't pay any attention to you. Mason speaks and introduces the woman lying beside him.

"This is Julie. She's my junior at the lab. I'll be showing her how to apply my de-aging serum today. She'll be practicing on you."

You nod and nervously swallow your saliva.

Mason turns and sits up on the sofa. Natalie moves over and keeps nibbling on his balls while Julie sits next to him and looks at you with a playful smile.

"Let's do it in the bedroom." - Says the dark doctor while guiding your girlfriend to stand up by the back of her neck.

Already knowing what you should do, you obediently walk back to the bedroom and lie on the bed. You pull your panties slightly down, exposing your tiny pale balls, and wait.

They follow you in, carrying the tools for the procedure. Mason stands at the side of the bed to pull your panties off completely. You squirm from his touch. Natalie, almost instantly after he stops, gets her lips around his dick.

"Julie" - Starts Mason - "First you need to disinfect the testes."

"Okeeeei~"

She puts on blue surgical gloves and takes a spray bottle. A chemical mist envelopes your crotch area. Julie grabs your cage with two fingers and sprinkles the disinfectant under your balls as well.

"Now, normally you'd apply an anesthetic, but our subject is already used to this sensation, so we can skip it." - He points at the syringe with a pink liquid. - "Take the serum and gently insert the needle into one of the testicles, then slowly inject the subject with it."

Julie nods and proceeds as instructed.

You close your eyes and feel a nervous tension all over your body. A little discomfort as your most delicate parts get pierced. It passes quickly. Julie begins pushing the substance into you. You feel heat and slight pain as if some detergent was purifying your testes.

The needle exits your skin, and you tear up a little, not from physical pain but because you become sad and feel emotional. The total loss of manhood. Humiliation. The lack of care from 'your' girlfriend, who's completely focused on her bull's cock. Your vulnerability in front of strangers. Your acceptance of the loss of agency over your body and whole life.

"Now take the second syringe and repeat it for the other one." - Mason continues with his instructions.

The girl replicates the same actions on your other ball. A few tears stream down from your closed eyes. Your expression, resembling a young girl about to cry, must amuse Mason. He chuckles and wipes your tears with his hand. The second injection is done.

He addresses Julie again - "Now we will administer the pills. A mix of anti-depressants and hormone replacement medicine."

He turns and extends an open palm with a few different pills to you. - "You were such a good girl today, sweetie. Here, these will make you feel better."

You hesitate for half a second but sit up and grasp the pills with your lips straight from his hand. No need to wash them down. With a trained throat like yours, you effortlessly swallow them all in one go and go on to suck Mason's thick manly finger. Teasing his finger by swirling your tongue around it like a pro, you look up into his eyes. He's pleased.

With a grin, Mason grabs your throat and pushes you down on the bed again. - "Let's get to your reward then." - He says.

He grabs a large towel and lays it on the bed. Effortlessly he grabs you and pulls you onto it. Your girlfriend, her face messy from keeping his cock wet the entire time, gets pulled up and sent to fetch the oil and lube. You assume Mason's favorite position - on your back, arms inside your knee pits, holding your legs up.

Natalie comes back quickly, holding two bottles.

"Prep your 'girl' for me." - Orders Mason.

Your girlfriend promptly obeys and pours oil on your ass, thighs, and around your crotch. She massages it in.

Mason inserts just a little of the tip of his cockhead into your boy hole. He pours a generous amount of lube where his dick meets your bussy. He momentarily removes his dick and allows your girlfriend to spread the lube on his cock before returning it to its rightful place - violating your ass. He slowly and smoothly inserts it into you, going back and forth.

You let out a moan as you feel him stretch you. Your body quivers. He's almost all the way in, and you instinctively try to push yourself onto him more. As he withdraws his shaft, your body tightens on its own as if it doesn't want him to leave.

"Ah, I almost forgot. We've got to adjust your cage." - Says Mason.

Your chastity cage is a flat and inverted cage that can be adjusted using its key. Mason and your girlfriend have been pushing your atrophied little nub further and further into your body for the past few months.

"Waaait, can I do it~??" - Asks Julie with a smug smile.

Mason chuckles. - "Sure." - And hands her the key.

Julie, still wearing surgical gloves, comes closer and gently grabs your balls into which she just minutes ago injected the feminizing fluids. With the massive BBC still inside you, the soft hand of a young woman inserts the key into the adjustment keyhole. She looks at your face to see your reaction before turning the key.

You look back at her with fearful anticipation. Her hand turns slowly, driving your withered penis deeper into your body. A soft, pleading grimace appears on your face, and a wicked smile on hers.

Half a turn. This is how much it was usually rotated, but Julie keeps going. Her expression reveals hints of joyful madness.

"Oh wow, I can feel you getting a little tighter. Nice." - Remarks Mason.

A full turn. You can feel your dicklette getting flattened. The slim hand keeps mercilessly turning. The pressure in your abdomen increases even more. Your lack of any masculinity asserted by unforgiving steel. One and a half turns. You can feel Mason's heartbeat through his cock.

"Uoh...~" - A lewd cry involuntarily escapes your lips.

The key stops. Julie slowly takes it out, still smiling and observing your face intently. She teases the area around your cage by slightly pushing her finger into your skin. The discomfort from the forced body modification gets stronger with her poking, and sweat appears on your forehead.

"This should be enough~~!" - She states happily and flicks your balls.

You flinch because of it and move a little making your boy hole squirm from the thick black cock that's still inside you.

"Mhmmmmmmmm." - Mason humms and starts moving his hips again.

His slow strokes make your mouth open wide. Your breathing gets faster, and you emit rhythmical girly moans matching the movements of Mason's hips. Natalie puts on some music and comes over to the side of the bed while Julie hugs the waist of the man stretching your asshole.

Mason swirls his dick inside your ass. The pitch and intensity of your moans rises. You already know what's coming. Strong, dark hands grab your waist. Your glistening, oiled body reflects the dim light. The pace of the BBC coming in and out of your tight ass increases.

Your eyes roll back, tears streaming from them. Your legs begin to shake and vibrate. You're about to cum. With each determined stroke, his superior dick fully embeds itself inside you.

You feel a slight tingle in your crushed, limp excuse of a penis. Your toes curl, and your head pushes back deep into the pillow. Just as the waves of pleasure start and you drip a little of your sterile slime, a manicured hand comes crashing down on your balls.

♫ PLAP ♫ - A pleasant sound of skin hitting skin fills the air.

Your girlfriend's palm hits your soft balls, making you cry out. The pleasure in your still shaking body gets drowned out by a throbbing pain, but another stroke of Mason's majestic cock brings it back.

♫ PLAP ♫

Again, a painful blow from a beautiful hand. Alternating sensations of hurt and gratification mix in your body and mind like ripples in a pool of water. The orgasmic high continues. Sounds of Mason's hips ramming into your butt and your girlfriend's violence mesh with the beat of the music.

The ballbusts become more powerful, indicating your girlfriend's unloving attitude towards you. Your body convulses, and Mason holds onto your body more forcefully to keep his dick from slipping out. Your longest orgasm yet, you're finally cumming like a real girl.

Vision melting, you begin to see colors and see music as if you were on drugs. Your mind goes blank. The only things you feel right now are the heartless smacks to your aching ball sack, and the, now pulsating inside you, black cock.

Heartbeat increased and gasping for air you try to focus on the blissful sensation of a black cock shooting into you and filling you with superior seed. His huge load coats your bowels completely. Another blow to the balls, the most powerful yet, makes you see a flash of light despite having your eyes closed.

Your body tenses on its own when the BBC starts withdrawing from your ass as if it didn't want it to go. Sweaty, drooling, hurting, and exhausted, you feel your body slowly give in. Cum slowly spills from your ass when Mason pulls out his cock from your sore, gaping asshole.

All your muscles relax, the tension fades, and you suddenly feel very tired. Ball slaps stop, and you peacefully pass out.

Sweet dreams~.
