It was the 31th of October, Natalie sighed with a smile on her face as her friend from school and current workmate, Lilly turned off the TV for the night. The duo had hung out together for halloween, having some of the usual, and not so usual fun for the season. The reason being Lilly, who is actually an experienced witch. She moulded her very home into a grand Halloween attraction for Natalie’s enjoyment, summoning various creatures to spook her as she went through, and ending the tour off sending the creatures back to their realms with gifts for their service, before finishing the night with a binge watch of various classic horror movies. All while partaking in various drinks of both alcoholic and archaic in nature
 
 
Natalie yawned and stretched herself onto Lilly’s lap, her short brown hair in a mess as she nuzzled drunkenly against her friend’s belly, hiccupping out bubbles that turned themselves into snakes that slithered away before popping. Lilly was had more restraint when it came to her drinking, only slightly tipsy, but enjoyed her friend’s closeness, patting the girl on her lap as the latter played with her long blonde braided ponytail. “Hey L-lilly~” Natalie belched with a silly look on her face. “Y-you are t-taking the w-whole november off, right~? W-where are you going~? Got some secret witch gathering to g-go to?” The woman rambled
 
 
Lilly smiled, replying playfully with her own question. “W-well, I do have plans for the whole month. But first, Nat, have you heard of this challenge called “No Nut November?”
“You mean t-the thing we made a bunch of guys fail last year with that anonymous live stream video?” Natalie replied rather smugly.
“Y-yes, that. I still can’t believe you talked me into scissoring you on camera. Was fun though.” Lilly chuckled, before leaning down to give Natalie a kiss on the forehead. “Anyway, what do you feel about trying it this month?”
“Don’t lie, you witch. We both know lewd is your true nature.” Natalie replied with a laugh. “Trying it? I can’t nut if I don’t have nuts, though.”
“True. But that doesn’t mean I have to admit it~. Anyway, You not having any nuts won’t be a problem, Nat. With my magic, I can give you some Nat Nuts~”
“Well then,that sounds like fun indeed.” Natalie replies with a smile, getting up and looking into her friend's eyes with both curiosity and a hint of lust, getting a bit more sober from the excitement. “What do I get if I succeed~?” She then asks, wanting to get a bit more other than just some lewd fun.
Lilly thought for a moment, before grinning as she replied. “How about half of whatever wealth I have, you have been asking me why I've been working with you despite all the money I have, maybe I’ll tell you the answer to that too if you succeed~.”
Natalie grinned as well, imagining herself being literally set for life with all that cash her friend has. “Deal~”
 
 
Natalie followed Lilly as the witch guided her to another room, her workshop where she prepares various potions. She felt a tingle wash over her body as she passed through the doorway, all the drunkness suddenly washing away, leaving her completely sober now, letting her watch her friend with focus and interest. She never got to see her in action before, but watching her work reminds her of Lilly when she is cooking, chuckling at the thought of the two skills possibly being similar. Getting a bit bored with the silence, Natalie asks. “So why are you still working if you have all this money anyway? You could just live out your life with all your magic anyway.”
“Well, I have my own reasons, but I also want to interact with others, than become a crazy old lady locking herself in her home all the time.” Lilly replied, getting a nod of understanding from Nat.
It wasn’t long before Lilly was done, and Natalie was very curious why there were three vials of different colored potions on the potion rack. One was a bright pink and filled half of a decently sized Erlenmeyer flask. The second was a milky white fluid in a test tube that seemed rather viscous, and the last one is a clear yellow fluid that quantity is so little that it is stored in a thumb sized container. “So, here they are. The pink one will give you your nuts, as well as a nice cock to go along with it~. The white one is for if you want to cheat a bit, and the last one is for a fun thing I have in mind~” Lilly informs, a smile on her face as she shows off her work.
“Cheat? What do you mean?”
“Well, I heard that one acquiring a new set of sexual organs might be rather overwhelming. This potion will help you in that regard. But I must warn you, using it comes at a price you have to pay me when the month is over~.” Lilly replies, with a big cheeky grin on her face, as if she is certain her friend would cheat at a moment’s notice.
“Well, ok… I mean, I might just drink that out of curiosity anyway, but sure.” Natalie replies with a blush and a chuckle, reaching for the flask. “So I just drink this? All of it?” She then asks in confirmation.
“Yes, It normally gets affected by alcohol too, but that should have been removed from your system by that barrier I placed. I can’t have myself working while drunk, unless I want a massive explosion.” Lilly replies, chuckling as her remark of casual destruction sends a faint shiver down Natalie’s spine.
 
 
Shaking away that feeling, Natalie takes the flask, staring at the pink fluid for a moment before removing the cork to sniff its contents. It smelled like sweet cherry, akin to soda, and she gave Lilly a grin before putting the flask to her lips and chugging the entire flask full of potion down. Placing the empty flask on the table, she patted her now full belly contently, feeling like she had just chugged a liter bottle of flat cherry soda, which was more or less what she had just done. “Can you strip for me, Nat~? I want to see it happen too.” Lilly remarks with a sweet smile, and Natalie nods in reply, a blush on her face as her body starts to feel warm. Lilly then lead Natalie to another room, bringing the potions with her. It was the guest room, the very same one Lilly had lent Natalie to stay the night. Placing the remaining two potions on the study table in the room, Lilly watched as her friend stripped in front of her, smiling to herself as everything was going according to her plans, and while her friend was distracted, began stripping herself. Soon, Natalir was completely naked, and she starts to feel her legs getting tired, deciding to lay down on the bed with her body fully exposed for her friend to see.
 
 
Natalie laid on the bed with her eyes closed, letting out a low moan as the potion got to work, her body getting more sensitive as she feels a tingling feeling in her nethers. She resisted the urge to finger herself as she felt her clit began to expand, growing in size into what she believes would be her new cock. Her focus on her own body was suddenly interrupted when she felt a hand grope her left breast, her eyes shot open to see Lilly naked and climbing onto the bed, stradling onto her as she gropes her breasts. “Gods, you look so beautiful like this, Nat~.” Lilly coos, rubbing her already moist slit against Nat’s navel, the woman wanting to reply, but only able to let out moans of pleasure as she feels every sensation multiplied. Lilly continues grinding against her friend, her butt moving lower and lower towards Nat’s crotch, soon rubbing against the already finger length clit. “It hasn’t even begun, and you are already moaning like you are in heat~. I wonder if you can even win this challenge~.” Lilly then chuckles, lifting herself off and going to the edge of the bed to see Nat’s transformation.
 
 
Lilly watched as Nat squirmed on the bed, the sensations of the transformation alone too much without her input. With a chuckle, she just laid on the end of the bed and watched, seeing Natalie’s clit expand more and more, the base of the clit bulging out as if the woman was growing a knotted, 5 inch cock. Lilly, unable to hold herself back any longer, lunged forward and engulfed the still growing member in her mouth, her moist maw on her fresh and sensitive member sending Natalie over the edge. It kept on growing in her, and when it reached its full length and girth, skin started to form around the organ, Lilly eagerly playing with the newly formed foreskin with her tongue. The knot formed into a pair of balls, dropping down into a hefty sac which covers her squirting pussy. The member twitches and twitches as Natalie cums, till the connection between balls and cock is complete, the freshly made seed shooting out, Lilly greatly enjoying the taste of her friend’s seed. With her seed finally released, Natalie laid down on the bed, panting as she caught her breath, hearing a loud and exaggerated gulp form Lilly as she swallowed.
 
 
“T-that doesn’t count, right?” Natalie moaned as she weakly lifted her head to look at Lilly, who was still hungrily staring at her friend’s new cock.
“Of course not~. But I won’t part with my fortune that easily, you know. Not without any challenge, anyway.” The witch chuckled, going over to the study table and accessing a hidden compartment in the bottom drawer, taking out two familiar, small egg shaped objects. They were bullet vibrators that the two of them used last year to pleasure each other after their stream. They are normal vibrators, enchanted with an energy elemental so they never run out of energy or vigor, no matter how long it is on for. Due to the enchantment, they also only activate at Lilly’s command, a thing that makes Nat gulp in nervousness. “You know, the cock growth wasn’t the only thing that potion gives~.” Lilly continues, sensually moving towards the bed. “Well, technically, but that cock isn’t normal, not in the slightest. It has some added features, which I'm sure will give you even more of a challenge~.”
 
 
Natalie watched as Lilly got to the bed, and shivered as her friend grasped her cock once more, taking one of the vibrators and pressing it against the tip of her member. Her eyes widened in surprise as the cock hole begin to open up, her hands clawing at the side of the bed as pleasure rocked her body once mer. The vibrator began sliding down her hungry cock, and it wasn’t long before her right ball bulged out with its new addition. Lilly fed the other vibrator down Natalie’s cock, evening out her orbs before commanding them to turn on. The pleasure was instantaneous, and Natalie came hard again, shooting her load right into Lilly’s face, her cock and nuts unwilling to release their vibrating prize. After a minute of osgasmic hell, Lilly had enough of the cum shower she got herself in, and commanded them to stop, Natalie having the longest orgasm she ever had, releasing a surprising amount of seed that now completely coats Lilly’s body.
 
“G-god… I- i can’t do this… N-no way…” Natalie gasped, trying to catch her breath, her hand going down to her crotch to massage her balls, shivering at the pleasure again.
“Are you sure~. I’m positive you will be able to do it, then we can both live together with all our money~.” Lilly chuckles, sensually licking the seed off her arms, eager to start the next part of the challenge.
Natalie looked at Lilly, letting out a lewd moan “B-but I w-want to fuck… I-It feels too good to cum~”
Lilly grins at Natalie’s lewd remark. “Well, we still have the cheat potion to help you, but you can only take it after I’m done prepping you up~.” She informs, getting up and going to the table once more, taking the yellow potion from the rack, and uncorking it. “I’ve been looking forward to this, by the way. Ever since I masted how to make that potion~.” She cooed, gulping down the yellow fluid as she walked towards the bed, the now empty container floating out of her hand and into the rack.
 
 
Natalie watched as Lilly approached her once more, noticing that her friend seems to get smaller with each step. Lilly got onto the bed, as she continued shrinking, approaching the member and nuzzling up against it, her size soon dwarfed by her friend’s meat. Her shrinking then stopped, her size akin to a doll, and at her size she enjoys nuzzling against her friend’s cock with her whole body. “W-what a-are you d-doing, L-lilly?” Natalie moans, as she feels her friend climbing up onto her still rock hard member.
“What do you think I’m doing, at this size, near your cock.” Lilly chuckled, as she got to the top of her friend’s cock. Natalie wanted to stop her, reaching down to pull her off, but Lilly saw that coming, tendrils growing out of the bed and holding her arms. “Don’t be a spoilsport, now. You will enjoy this, I’m sure~.” She coos, sliding her leg down into Natalie’s greedy cock hole.
 
 
Natalie arched her back at the pleasure, feeling her friend slide down into her hungry cock. Lilly moans as she is sucked in, enjoying the tight muscles squeezing down on her as she is sent deeper. “S-see you in a m-month, D-darling~.” Lilly coos, as her head gets engulfed by the cockslit. The tendrils let Natalie go once Lilly is halfway down her cock, letting her squirm in pleasure as Lilly filled out her right nut. She soon came again from the squirming as Lilly got comfortable, but like before, her member refused to let anything except her seed out.
 
 
A few minutes pass before Lilly calmed down, enjoying her cum bath so much that she fell asleep almost instantly. Natalie, now alone with her sleeping friend in her balls, got up off the bed weakly, her eyes going towards the remaining potion on the table. “I c-can’t do this. S-she f-feels so good inside me ...” She mutters to herself, stumbling towards the table. “Fuck whatever she wants for me. I-if I have her money, I can g-give her anything anyway.”
In a swift motion, she opened the test tube and gulped the gooey contents down, shivering uncomfortably as she feels it sliding down her throat.
 
 
She waited for a moment, before feeling her body heat up again as the potion began to work. What she didn’t expect was her cock suddenly shrinking, her balls still remaining with all the cargo within it. “N-no no nono !” She cried out,grasping at her shrinking cock as if she was trying to pull it back out of her body, but soon the member was gone, replaced once more with her clit. She then heard a muffled laugh from her balls, Lilly having been rather rudely awakened by the commotion.
“I guess you took that last potion, you cheater~.” Lilly remarked. “Well, you can’t nut if you don’t have a cock to shoot it from~. So I guess you can certainly win now~.”
“B-but… H-how do I g-get you out later? Y-you are stuck in me!”
“Don’t worry, I already knew this would happen. The pink potion is rather permanent, but this lasts only a month. When it wears off, you can finally nut me out, Nat~” Lilly chuckles.
“W-wait… you planned all of this, didn’t you? No wonder you took a month off work!” Natalie exclaims.
“I say a month long stay in the Nat Nut spa is a welcome vacation, though~. And if I get a cute husband while I’m there, all the better~.” Lilly replied cheerfully., giving the walls around her a gentle lick which sends a pleasurable shiver through Nat’s body.
“H-husband? W-wait… Is what y-you want me to d-do ...marry you?” Natalie asks, nervous.
Lilly lets out a chuckle, but doesn’t reply, snuggling up against the vibrator that is with her as she closes her eyes, enjoying her stay in her friend’s balls.
 
 
Not getting a reply from Lilly, Natalie sighs. She would be lying if she said she wasn’t attracted to Lilly too, so it isn’t all that bad. She looked around the room realising the massive mess she made, and glad that her luggage was safely stored in the wardrobe, away from the line of fire. Deciding she doesn’t want to sleep in a seed soaked bed in a musky room, she went to wash whatever seed she had on her and moved to Lilly’s room to sleep. She is starting to get used to the weight between her legs when she got out of the shower, and when she got to Lilly’s room, she saw a pile of underwear, with a note on top of it.
“Hey Nat, I know walking around with a pair of balls would be annoying and awkward for you, so I prepared some special underwear for you. A pocket dimension within them hides your balls, so you can still wear your work skirt without anyone knowing of your package~. A little warning though. The dimension might not be uninhabited, and some things might come and play once in a while~.”
“God dammit, Lilly. You pervy witch.” Natalie mutters, as she takes one of the underwear off the pile and puts it on, feeling her balls slide into fabric of the panties, and into the pocket dimension. “Well, at least it fits nicely.” She sighs, moving the rest of the pile to the edge of the bed and laying down to sleep.
 
 
----------------------
 
 
A whole month has passed. Lilly was not wrong with the creatures coming out to play. More than once a tentacle began groping at her balls, massaging them and the passenger within. Her balls continued to grow as they kept on producing seed, unable to release it. By the time she could feel the white potion wearing off, her balls were the size of beach balls, gurgling and sloshing with cum. Another issue Natalie found was that Lilly’s shrinking potion didn’t last as long, the witch having returned to her full size in half that time, bulging out her sac even more. Natalie returned to Lilly’s house, rushing to the currently drained grand bath located in Lilly’s basement, feeling the heat of her body as her cock began growing again. She almost ripped off her clothes as she rabidly stroked her growing cock, wanting release, her hips grinding against her massive balls.
 
 
She stroked and she stroked, feeling the connection between cock and balls inching closer and closer. Then, with a loud howl, she finally got release, shooting her pent up seed into the pool. Her orgasm lasted for over 20 minutes, her balls draining of all it had. Lilly had been shot out at some point, and was still blissfully soaking herself in the seed, completely saturated in her lover and friend’s seed. When Natalie’s orgasm finally ended, Lilly swam over to the edge of the pool, pulling herself off and giving Natalie a kiss on the lips, sharing some of the tasty cum she had been consuming for the past month. “Good job, darling~.” She coos, cuddling up against Natalie, moving the weak woman’s hand to the small bump on her belly. “We are going to be one nice, happy family~.”
