Lessons In Potion Brewing Pt 07

-This story continues to get wild with the exaggerated effects of the potion. If you don't like the story tags, you probably won't like this.

---------------

Lidiya led her sister and son to the basement of her gothic Tudor mansion, down deep to the dirt floor and unfinished stone walled cellar. They passed through old wooden shelves filled with crates and boxes stuffed with various artifacts and manuscripts. Standard fare for most Witches. It was a dusty place, and was mainly only used for storage. The potions laboratory, however, was a finished room in the cellar, complete with tiled floor, plastered walls, plumbing, electric- all the modern amenities. Lidiya had even added a double bed for long nights that called for a relaxing break, or potentially a test drive of what she was cooking.

Danielle took the lead once entering the lab, still only dressed in a bra and leggings. Lidiya had donned a satin thong panty and a thin tank top that displayed her matronly nipples. Julian threw on a pair of boxers and couldn't take his eyes off of the curves displayed by both his mom and aunt.

The thong that Lidiya wore glistened in the light with a satiny sheen. She wore the panties high on her hips as she walked, forcing the back to disappear between her shapely butt. It drew attention to her long, toned legs. The front of the panties hugged her mound snuggly; the cleft of her tight pussy was evident and made it obvious that she was clean shaven. The shirt she wore teased anyone who saw it, despite the lack of bra, her breasts showed little to no sag and her nipples seemed to be perpetually hard.

Danielle on the other hand was still wearing skintight leggings that hugged her exaggerated curves. While Lidiya had a more svelte and muscular, a more toned appearance, the word 'Busty' came to mind when looking at Danielle. Her leggings looked panted on and hugged her thick hips lovingly. Her butt bubbled out from her legs and begged to be spanked. Her massive bust was barely concealed by her bra and shook wildly as she moved through the basement, each movement of her torso drew attention to her tits and tempting cleavage. Despite having cum a couple times that morning, Julian found himself ever adjusting his hardened cock as he stole glances of his mom and aunt.

"Ok, let's try this again using the same ingredients that Julian used last time." Danielle suggested.

"Only this time, we're going to interpret the temperatures and time frames a bit more precisely." She continued.

"Julian, could you please use a notepad to take diligent notes so that we can compare to future trials?" Lidiya asked.

Julian took charge of documenting the process as his gorgeous mom and aunt got to work. They mixed, distilled, heated and cooled various combinations of ingredients. He noticed that they were much more precise than he was during his last attempt at brewing. They also looked so sexy in a strangely academic way when they measured quantities of various liquids in beakers and poured them this way and that while wearing barely anything. As the mature vixens leaned over the lab bench, he couldn't peel his eyes away from the way his mom's panties were being pulled tight between her butt as she stuck it out. His mind drifted as he dreamt of the way the two women stroked his cock earlier that day while discussing plans for potion brewing. Julian was caught with the urge to drop to his knees, pull the thin fabric of thong aside and rim his beautiful mother before pulling the leggings down and doing the same to his busty aunt. The way his mom had previously reacted when he tongued her sexy butthole made the cum in his balls churn with desire.

Once the potion had be properly brewed, it still had to sit for some time at a designated temperature. This was a crucial part- too much or too little heat and the potion may not have any effects and all of their work would be wasted. Danielle was fairly certain that along with her nephew's report, they had it correct. Now it was just a waiting game.

"We should do some additional baseline measurements while we wait for the potion to finish." Danielle said seriously.

"Excellent idea, Danielle. Then we'll have an idea of how far things can be taken. Are you ready Julian?" Lidiya asked her son.

"Sure thing, just tell me what to write." Julian was ready with the lab book but wasn't sure what she was planning to measure- the only thing left at the station was the cauldron full of the steeping tonic.

Lidiya fished around in top drawer of the brewing station and pulled out a cloth measuring tape. She then pulled her thin T-shirt over her head exposing her gorgeous breasts to her son. Julian's cock was already at half-mast while watching his mature mistresses' parade around in barely anything, but now he was fully hard. Lidiya wrapped the tape measure around her chest just under her breasts and looked at the markings. She then moved the tape measure to the fullest part of her breasts and did the same. She did some quick mental math and then moved the measuring tape down to her waist and hips. Julian's blood pumped through his cock as he noted the way she looked in nothing but a skimpy thong.

"That comes to about a 34C for cup size, 28 inches for my waist and 34 inches for my hips. Got all that Julian?" Lidiya asked.

Julian nodded as he broke himself from the trance. Lidiya handed the tape measure to Danielle who then did the same process. Beginning with removing her black lace bra and then her leggings, revealing a matching pair of thong panties. As she measured Julian noted the differences in the pair. His mother was way more toned than his aunt, while his aunt was way bustier. He looked on eagerly as his aunt pulled the tape tight across her mountainous breasts, then again to her thick hips.

"36EE for my bust, 32 inches for my waist and 38 inches for my hips." She told her nephew whose cock was straining against his boxers.

Hearing his mom and aunt talk about their measurements was a huge turn on for the boy. He couldn't wait until they took them again after drinking the potion. At that point, Lidiya took the measuring tape back from her sister.

"You're turn, honey." She told her son in a sweet voice.

Julian glanced down at his impossibly hard erection, he noticed that precum left a wet spot in the front of his boxers. He was still holding the lab book and pen. He hesitated for a moment, wondering where he should put those things.

"Here, let me help you, sweety." Lidiya said lovingly.

Julian's mom squatted down in front of him, legs spread on either side of his as she braced herself. Her ass cheeks swallowing her panties, her butt was tensed in this position and it stuck out beautifully as Julian looked down at her. Lidiya grabbed his boxers and pulled them down over the bulge in his underwear, freeing his hard cock and nearly smacking his mother in the face in the process.

"My, you've got such a beautifully big penis, baby- lets get your baseline measurements before you get even bigger." Lidiya said.

She wrapped her manicured nails around his shaft and stroked it gently. Danielle licked her lips as she watched the mom stroke her hung son.

"Gotta make sure you're at full mast..." She continued.

"I wouldn't worry about that mom, watching you and Aunt Danielle parade around half naked has done a number on me." Julian replied.

"Oh, my poor baby's getting blue balls? Don't worry, Mommy and Aunt Danielle will take care of you soon- just be patient, baby." Lidiya told him.

Lidiya held the measuring tape against his pelvis and measured the length of his shaft. Then she wrapped the tape about midway along his shaft to measure his girth. Julian's cock twitched as his mom measured him, the gentle touch was driving him wild.

"Looks like 7.2 inches in length and 4.2 inches in circumference. Make sure to write that down baby." Lidiya instructed.

Danielle was stirring the cauldron as Lidiya measured her son. Still topless with her massive tits shaking as she moved the ladle through the liquid. As the smell wafted from the container, she took a deep breath. The aroma filled her nostrils and immediately coursed through her blood, making her nipples stand erect. Shortly after that, her phone began alarming on the bench next to her, notifying them that the potion was ready to be trialed.

"That's it, who's ready?" Danielle said as she ladled 3 big scoops of the brew into mugs and passed them to her sister and nephew.

"How long did it take to feel the effects the first time?" Lidiya asked her son.

"I felt it immediately, but they gradually progressed over time." He responded.

"Yes, the absorption may have been a bit prolonged if it wasn't brewed with precise time and heat. This dose should be fairly instantaneous. Between 2 and 5 minutes if I had to guess. It may not last as long though, maybe 6 to 12 hours? Hopefully that will give us enough time to understand the effects and figure out where adjustments can be made." Danielle said rather confidently.

"Well, bottoms up- pun intended." Lidiya said as she tipped the cup back. Danielle and Julian followed suit.

As the warm liquid ran down their throats, it left a burning sensation not unlike a strong alcohol would- but this was much more palatable than Julian's previous attempt. The warm feeling spread as it reached their stomachs, causing a tingling sensation course throughout their bodies. Julian could immediately feel his cock throb as it became engorged with blood, the warm feeling washed over his balls and through the rest of his body. His muscles felt tight, like they would after a heavy work out and he felt... bigger everywhere and stronger too. Looking down, his veins coursed with enriched blood and his boxers looked on the verge of tearing as his growing cock and balls filled them, he could feel the fabric of his boxers pulling tight as it stretched.

Danielle and Lidiya's bodies were reacting differently, their breasts swelled with every labored breath and grew almost instantaneously as the potion coursed through their veins. Their naked nipples protruded out obscenely as an extension of the huge mammaries. Both of the sexy witches could feel their clits tingle as sensations of pleasure pulsing through their nether regions. As their clits grew, they caused their panties to bulge and bulge until each clit created a tent, pressing against the inside of their skimpy panties. Both Danielle and Lidiya could also feel a unique sensation deep inside, almost as though each of them was discovering new nerve endings that stimulated them from clit to asshole. Both of their pussy's reacted similarly, oozing honey into their panties from swollen lips.

Danielle's clit bulge wasn't as big as Lidiya's, but her breasts seemed to have nearly doubled in size. Her hips looked wider too, it was as though the most feminine aspects of her body were exaggerated by the potion.

"Fuck, I feel incredible." Danielle said as she rubbed her panty bulge with one hand, trapping her clit between two fingers as she rubbed up and down and then pinching one of her throbbing nipples with the other hand.

"I know, the feeling of euphoria is almost instantaneous. My senses are stronger, I can... I can smell you, Julian." Lidiya panted as she looked as she was in heat. "God you look sexy, Julian- you look pumped like you've just been in the gym." She continued, licking her lips.

Danielle rubbed her hands against her busty body all the way down to her panties. She pulled her panties to the side and freed her engorged clit from the fabric, holding the tape measure along the length she read the number's allowed. Similar to the effects that her sister had experienced last time- She noted that her clit appeared to look more like a cock, even if it was a bit small, it was complete with an opening that she lewdly hoped would expel cum if she was lucky.

"3 inches, hmmm not as big as what yours looks like, Lidiya. Such a filthy feeling to have such a big clit- and yes, it looks more like a little cock than an actual clit... but my breasts seem much bigger- lets get those measurements... yea wow- 32 HH based on this measuring tape. 30 inches for my waist and 42 for my hips. I feel like such a bimbo with this hourglass figure." Danielle stated matter of factly, knowing full well that her body had taken on a porn star appearance.

"I think you're little clit-cock is cute, Dani, I can't wait to see it shoot cum." Lidiya winked.

She handed the tape measure to Lidiya who then went through a similar process. After rubbing the bugle in her tight panties a few moments, her them down to reveal a more markedly transformed clit. It looked much more like an average cock, she tugged the erect tissue to coax it to full length before measuring it at 6 inches in length and 3 in circumference. As the sexy Witch massaged her newly engorged clit she felt a deep desire to fuck her sister with it. Returning to the process though, she pulled her panties up to trap her swollen clit-cock and moved on to other measurements. Lidiya's breasts had grown to a 32 DD and similar to her sister, her waist had gotten smaller and her hips a touch bigger, measuring 26 and 36 inches respectively. Her body had an even more toned appearance than before and now her muscles rippled as she flexed. Lidiya's fit body looked like that of an amazon princess.

Danielle stared intensely at Julian's growing cock, she'd teased herself long enough and needed to be sated. Her attempt at being clinical about this process was thrown out the window as potion overpowered her with lust, she walked over to her nephew and dropped to her knees. Without hesitation, she pulled his underwear down, letting his massive cock flop out and nearly hit her in the face. As she saw the veiny monster in person her pussy was swamped and her nipples and clit-cock throbbed.

"Quick Lidiya, measure him before we get too carried away-" Danielle instructed.

The sexy aunt ran her hands up and down the monstrous appendage as his mother approached him with the tape measure. Danielle stroked him up and down with both hands, unable to wrap them fully around his girth. Lidiya's pussy reacted similarly to viewing her son this way, her pussy tingled with lust and anticipation. As she lay the tape measure along his length Lidiya was amazed at how hot and hard he was. She couldn't wait to be filled again.

"13 inches long, 7 inches in diameter." Lidiya spoke as her mouth went dry.

"He looks bigger than last time, almost like that big 40-ounce water bottle you carry around, Danielle" Lidiya giggled.

Danielle at this point had seemingly lost control as her mouth enveloped the head of his cock. Her eyes rolled back in her heard as she savored the taste and feel of the big tip. She ran her tongue around the ridges of the flared head and tongued his piss slit, lapping up the freely flowing precum as her hands worked up and down the shaft. She tried to force him deeper in her mouth as his mom watched but was unable to. Lidiya held the back of her sister's head and forced her to deepthroat the massive cock. Danielle gagged and reeled at the pleasure of sucking such a beautiful cock so deeply and being forced down on it by the owner's mother no less.

"Holy hell, that feels incredible. Suck my cock Aunty." Julian groaned.

Danielle bounced up and down on her knees, even with help she could only take about a third of the length in her throat before she was left gasping for air. She gagged and spat as her saliva flowed out of her mouth like a faucet. The slutty witch drooled all over, spit ran down Danielle's face and covered her enormous breasts as she fed upon her nephew's cock.

"Fuck that slutty mouth my sexy son. It's making mommy so hot." Lidiya said as she forced her sisters head down.

Lidiya too horny to ignore her body any longer. The sexy mom pulled her tiny panties to the side and gripped her girl cock. Wrapping her fingers around it, she tugged slowly while watching her sister suck her son. Stroking the her clit cock was such a heavenly feeling. The act sent tingling sensations through her body and made her pussy drip below. Lidiya pulled her sister's hair back, forcing her mouth off of her son. She then pulled Danielle towards her; Danielle's mouth eagerly found its way to Lidiya's cock. Her length paled in comparison to her son, and Danielle easily took the whole thing in one go. Danielle's nose was pressed against her sisters' pubic bone as she felt her girl-cock tickle the back of her throat. Lidiya pulled her hair back again and then thrust forward, fucking her sister's wet mouth like it was a pussy. Danielle's saliva dripped down her sisters' shaft and mixed with the wetness of her horny pussy.

"Fuck sis, your mouth feels incredible." Lidiya moaned as she face fucked her sister.

After enjoying her mouth for a few moments, Lidiya pulled her sister off and up to her feet. Lidiya sat down on the couch at the opposite end of the room and guided her sister back onto her cock. Danielle wasted no time getting back to work, licking Lidiya's sopping pussy and working her tongue up the shaft of her cock before taking her in her mouth. Julian watched as his aunt went down on his mom, stroking his mammoth cock. Julian moved towards his aunt, grabbing her thick hips from behind he rubbed the head of his prick against her tight cunt. Danielle pushed her ass backwards, begging to be penetrated. From this angle, Danielle's busty hips and ass looked made for sex.

Julian worked the head of his huge cock between his aunts' oily pussy lips, her cunt was on fire and Danielle moaned like a whore around Lidiya's girl cock as her nephew pressed into her. Lidiya sat back with her legs spread, watching her son mount Danielle from behind and enjoying the vibrations that the moaning sent through her body.

"Fuck your slutty aunt, baby, she wants it so bad. Pound her tight pussy from behind while she sucks your mommy." Lidiya instructed.

Julian held Danielle's hips and drove his cock deep inside her pussy. The bulbous head spread her sopping labia and Danielle groaned, her cunt muscles stretching as he filled her. She briefly tried to pull away before pushing back towards it. Her eyes rolled back in her head as her nephew fucked into her. Her pussy felt impossibly full as the enhanced penis filled her to the brim. She'd never taken anything so big, when she first saw it, she wondered if it was even possible- but the sensation that ripped through her was pure pleasure. Every thrust set her nerve endings on fire. Her tight hole hugged every vein and ridge as it tried to keep him inside.

"Oh god, so good Lidiya...." The witch moaned.

Julian pumped his big cock in and out of his aunts tight cunt, watching her ass ripple with every thrust.

"That's it, Slam that big dick deep inside of her, do it for mommy." Lidiya coached, still sitting with her legs spread, enjoying her sisters mouth sucking her girl cock.

Julian fucked his busty aunt hard, driving her body forward with every thrust and forcing her mouth onto his mother. His engorged balls swung with force and slapped against his aunt's petite clit cock as he bottomed her out. Julian was overcome with lust as he watched his aunt's busty ass bounce back and forth in front of him. He slapped it roughly before massaging her meaty butt. He moved his thumb between her delicious cheeks and slowly buried it in her asshole. Julian could feel his cock press against his thumb as he fucked in and out.

"Uuuughhhhhhhh...." Danielle moaned around her sister's cock at the invasion of her anus. "YES! Finger auntie's filthy ass while you fuck her!".

Danielle's body was electric with sensation, she felt like an absolute whore and loved every second of it. Her cunt was being pounded by her hung nephew while she choked on her sisters clit. Danielle felt her first of what hoped to be many orgasms abruptly over taking her and sucked hard on her sister as it washed over her.
