There's room for multiple slut-personas

You grabbed Stacey by her hair and pulled her back roughly. "Ouch...What the fuck are you doing?" She said it with anger, but in a clearly aroused way.

Pulling the marker out of your pocket you reply forcefully, "Don't like my balls? Let's fix that." You reached down and wrote across her upper chest: "Loves Big Sweaty Hairy Balls"

Recapping the lid, you could instantly see Stacey's entire demeanor change. Her eyes narrowed on your nuts, like everything else faded. Without breaking her focus, she asked a simple question "Josh... what did you just write one me...because I suddenly want to smother my face in your nutsack."

She moved back towards you balls, lifting them up above her face. She started at them with a sheer look of lust. Closing her eyes, she moved her face even closer and took a deep breath, her lungs filling with your musk scent. As she could breath no more Stacey opened her mouth, bit her lip, and visibly shuddered. With the sudden chill passing, Stacey opened her mouth and started a long lick from your taint upwards. You could feel her smooth tongue covering every wrinkle and bump and her heavy breathing filled the air with noise.

You wrapped your hand through her hair and pulled her back. She looked up with shock and with a deep need. You could feel her straining to move back to your nuts, but you just loved teasing her.

"Like them a bit more now eh? Describe it for me, my little ball-whore."

She couldn't quite reach your nuts with her mouth, but her heavy breathing continued. "It's hard to explain... it's like the smell is just heavenly. Like the best smelling cologne or cookies out of the oven. It's intoxicating. That first deep sniff and I could feel pussy explode in warmth. And the wrinkles and the skin. Every crevice is another valley I want to explore with my tongue. Your hair... it was gross before but now I want to bury my nose in every tuft. And ...and... the fact that your delicious cum is waiting inside, it's almost too much. I just want to suck your balls so hard I pull the cum out! But they're too big!"

Her short speech was so arousing that your cock strained against the air, it rising slightly as tensed your muscles down below. If she kept this up, you might not last that much longer.

You let her go and she dove back in, returning to her constant licking, slurping, and occasional kisses. After a minute or so of her bouncing back and forth between each nut, you noticed her right hand ventured down her crotch as she clearly started to finger herself. She wasn't trying to hide it and it would have been impossible to anyway. She was so wet that even the slightest movement of her fingers make a loud schlicking sound.

While you enjoyed the sights, sounds, and of course feels, you figured you could make her enjoy it even more. Grabbing the marker you flipped your left forearm over and wrote: "Super Sweaty Balls"

It only took a couple seconds before Stacey's moans increased in volume. Glancing down you could visibly see the droplets of sweat around your groin and it was quickly being transferred to your girlfriends face. A second later and the smell hit your nostrils. It was rank! But Stacey loved it so all the better you supposed.

With that you found a remaining sport on your left arm and wrote: "Thick Pubes" The feeling was hard to describe as you physically felt the hair surge out of your skin. Soon you had what could only be described as a bush and your balls were covered in countless stray hairs, curly, long, and thick.

Again, Stacey's moans increased and her licking intensified. She was pulling on your nutsack with her teeth, trying (unsuccessfully) to suck a ball into her mouth, and rotating between loving kisses and straight up slobbering. She pulled away for a moment, in part to gather her breathe, but likely also to show you her face. It was a total mess, her makeup ruined and dripping down her cheeks. Her slobbery combined with the sweaty moisture of your nuts and left her face drenched. You could even spot a couple stray pubic hairs.

And to be honest, it was incredibly hot. Stacey, your girlfriend, had become a total slut for your nuts! And that was nuts! What girl actually liked balls? Liked the smell? The hair? It was so degrading, but here she was lapping it up like it was the best possible thing in the world! The thought of the whole situation made your orgasm approach ever quicker, though you could only get so far with love to your nuts.

You pulled Stacey off you again and gave her instruction. "Babe I love the enthusiasm, but if you want my cum, you gotta give my cock some loving too."

It was only a short comment, but it seemed to awoke something in her. As if she had forgotten her other true love: cum. The nearly hypnotized delirious look in her eyes was replaced with lust as she started jerking your cock with her left hand, her other hand still buried in her panties and schlicking away. Her mouth moved over your head as she started sucking you for all your worth.

Her tongue danced around your cock. First around the head and then long licks down and back up the shaft. She didn't forget to give your balls the occasional lick, but she got the message and stuck to your cock. She tried to throat you, but only got so far, about halfway down. You always had tried to get her to do more, but her gag reflex had (and still did) stop her. Certainly something you could fix later.

All the while she interspersed her tongue bath with some of the dirtiest phrases you had ever heard: "Shoot your cum all over your dirty semen slut!" "Just drag your nuts over my face until all I can smell is your sweat!" "Fill me with your ball juice until I can't move!"

With each lick, each iteration of degrading language, each audible pop as she sucked your head, you got closer to your finish. And she said something so hot that you blew: "My only purpose is to suck your balls and drink your cum!"

The first string shot out like a bullet, going straight over Stacey's face and hitting the wall behind her. But she reacted quickly and made sure her mouth was around your head before the next load shot out. The second went straight in her mouth, her cheeks bursting outward as they filled with cum. The pleasure was becoming too much for both of you. All you could see was pure white, with each load shooting out bigger than the biggest orgasm you had ever previously had. Which was a shame because without the blinding pleasure you would have been able to see Stacey's reaction.

As the second load filled her mouth, Stacey's eyes rolled backward. She tried to scream, but her mouth was preoccupied, so it only came out as a deep groan. Her right hand was still in her panties and her fingering and rubbing went into overload. The delicious taste in her mouth, the musky sweaty smell of your balls combined with the bleachy smell of your cum, the thick sticky texture in her mouth. It all became too much as Stacey had a mind-shattering orgasm. Despite her mind being gone in bliss, her body still managed to pull your cock out of her mouth, aiming it at her face where the fourth and fifth string hit with so much **** that Stacey was physically pushed back, while her face became absolutely covered , gluing her eyes shut.

Her hand let go of your cock as she lost her sense of place. The sixth load managed to shoot across her long brunette hair draping over her shoulders. The remains of your orgasm (still several shots more) covered her neck, chest, breasts, and stomach. It was like some freak horror show, your enormous balls just absolutely coating Stacey in an ungodly amount of cum.

And then you both passed out from the pleasure.
