Something Special
by BangBear


Trevor set the bags down in his kitchen with a huff, questioning if it was really worth carrying everything at once to save a second trip to his car after all. He’d made the run for groceries on his own on the promise that his mom would do “something special” for him. He could only wonder what she was talking about, considering that what was normal to them was far beyond taboo for most.

“Hoo, my fingers…” he groaned, looking at the painful ridges the plastic handles left on his digits. Trevor blew on them and shook them out, coaxing the blood flow back into them and smoothing down the lumps.

“Oooh, look at my big strong man,” Joanna embellished, walking up behind him and putting her hands on his shoulders. “You brought in aaall these at once? So impressive!” He chuckled, rubbing his hands together to innervate them. 

“Yeah, well, you know me. The big strong man of the house,” he played along. “So, special surprise?”

“After we put these away.” She kissed him on the cheek and then moved to start putting the goods away one bag at a time. He joined in, the two of them putting things away in the fridge and pantry. It was quick with the two working together. Joanna turned to her son as she set the last can from her bag away in a cabinet. He was nearly done, but she let him tackle the rest on his own.

“I’ll be in your room. Don’t take too long, now,” she teased, heading up the stairs. His tail flicked once, ogling his mom’s shapely ass in her jeans. He was quick to put the rest away, but careful to not be haphazard with it and suffer her wrath afterwards. After the last pack of bacon was tucked neatly in the fridge, Trevor stomped up the steps and jogged to his door. Once inside, he saw his mom sitting on the bed, her legs tucked together in front of her and supporting herself with one hand on the bed to her left. 

“Hey there, Mr. Man. Come get your special something,” she invited, her tail flicking on his sheets as her legs spread for him, her lips already glistening in the daylight. 

It didn’t take much more than that for his pants to start feeling uncomfortable. Trevor huffed and tossed his clothes aside, his mom giggling as he practically charged her. Their lips met and their arms wrapped around each other, laughing like new lovers coming together again. She could feel him poking against her leg as they pecked each other with little kisses, gradually getting closer to his destination. Joanna put a hand down between her legs to stop him before he got himself too carried away.

“Hold on, sweetie, I have to show you your surprise.” She scooted back to put some space between them, Trevor reluctantly letting her go. She leaned back and reached down between her legs to part her lips. “Aim a little higher this time,” she said.

Trevor’s mouth fell open. “No way, for real?!” She gave him a simple wry wink back, her right index finger rubbing over her urethra. He huffed and crawled forwards towards her, kneeling between her open legs. He took his cock in hand and aimed it down, his tip against her pisshole. Joanna bit her lip as she felt him pushing against her. He deflected off a few times during his entry attempts, his cock sliding up along her clit or down between her lips. Either direction got sharp, pleasured hisses from his mom.

“That’s alright, sweetie. It’s awfully tight. Just keep trying,” she encouraged. Trevor moved his hand up his shaft, closer to the tip for more precise aim and control. With his next attempt, it actually felt like he was gaining ground. Joanna’s hand gripped the sheets as she looked down, watching her son slowly but surely slip inside her urethra. “Ah, angh, you got it, baby! Just keep go-oooh!” 

She threw her head back and nearly tore the sheets with her claws as his head popped inside, Trevor swearing above her at the incredible tightness he found gripping around his shaft. He had to keep a conscious effort to stay inside her as the taboo tunnel tried to eject him. She returned her eyes to him, a look of hunger on her face. A familiar look that told him she wanted him deeper. 

Joanna groaned in bliss as he obliged her, pushing another two inches of his shaft steadily, and with great effort. “Holy shit, mom, you’re so fucking tight here…” He pulled back, but it could hardly be called that. More he allowed himself to be pushed back out by her, only for him to slide in once more.

“I can take you, baby, keep going,” she reassured between huffs. “C’mon, I want more.” He started thrusting now, his cock sliding further into his mother’s pisshole as she groaned with each centimeter he advanced. “Fuck, almost…” she groaned, seeing his knot approaching her.

“Hah, is, is this real? This can’t be real,” he panted. Joanna reached up to grab him and pull him in for another kiss.

“You’d best believe it. Otherwise you’re gonna wake up soon and have to head to class.”

“God, don’t say that,” he chuckled, kissing her again before she fell back to lay flat on the bed. He watched her bounce under him, her heavy breasts rolling in circles in time with his hips, her arms laid straight behind her above her head along the bed. He took them in his hands, ceasing their wild gyrations and replacing them with teases and pinches until her milk sprayed from them and showered back down on her. She giggled up at him, giving him a wink as she lapped up a few droplets that landed near her chin.

She felt the sudden widening of his shaft pressing against her and mashing on her clit with each thrust. Her head was thrown back again at her son pushed her button over and over. She quickly approached climax, and Joanna’s left leg seized up, her toes flexing and spreading unevenly as her foot trembled and shook. She took his pillow over her face to muffle her screams as she came, spraying her son with a gush of her juices. She clenched hard on his cock, milking the hell out of him on his thrusts in and out of her.

“Fuck, mom, I… I’m not gonna last long! I gotta… fuck…” he moaned breathlessly. He pushed in as hard as he could now, mashing his knot against her urethra and shoving himself forward. He could hear her muffled, screaming moans get louder from under the pillow.

“Trevor wait!” she called and moved the pillow away, but it had taken her too long to realize what he was doing. With a deep grunt, his knot popped securely inside her urethra. He could feel his tip bathe in her urine as it forced its way into her bladder, and a moment later began adding his own fluid directly into the reservoir. 

Trevor’s cock throbbed hard as he came in his mom’s bladder, bloating the organ as it overfilled. Pleasure ruled over his face, his heavy, drawn out moans filling the room. Joanna breathed shallow, the urge to pee rising as a second fluid entered. She gripped the sheets hard, her attempts to satisfy the urge blocked by his invading wad of flesh. After a few moments, Trevor slumped down, his hands planted at either side of her body holding himself up on the bed and the tension leaving his body.

Joanna’s tension was only growing, on the other hand. Looking down, she could see her bladder bloated out ever so slightly. She huffed, a grin breaking through her mixed emotions. “I didn’t plan for this…” 

“Hah, I, hah, figured you wanted my knot, too,” he panted. Her leg started quaking again, but for a different reason this time.

“God, I have to pee so bad but…” she groaned. “I can’t. I didn’t think I could get knotted there.” He looked incredulous.

“Dad hasn’t done this?” Joanna shook her head.

“He’s way to big to even attempt that. He can only get half in. This is uncharted territory, sweetie.”  A proud little smile crossed his lips thinking about how jealous his dad would be when he found out. “Ngh, shit, we’re gonna be here a while, honey.” Her leg continued shaking from her desperation for the bathroom.

“Good thing we put the groceries away.” Trevor adjusted himself into a kneeling position to rest, the shift stirring his cock around inside his mom and making the feeling surge withing her again. Joanna bit her knuckle and winced, hoping they wouldn’t have to wait too long for him to be freed. They sat in silence for a few minutes until…

“Uh-oh…” Trevor said.

“Uh-oh?”

“Yeah, sorry.” She furrowed her brow at him. A moment later, she felt what he was talking about as a fresh rush of fluid filled her further.

“Ah, Trevor stop! Stop!” she begged, trying to push him away.

“Can’t, sorry. You gotta go when you gotta go.” A relieved sigh announced his contentment in emptying his bladder and overfilling his mom’s. It swelled up her lower abdomen even further, and she gripped the sheets tight. Her breathing was heavy and deliberate, and she was forced to chest breath, as stomach breathing put far too much pressure on her bladder for comfort. 

“Ngh… Fhuhck… you’re in so much trouble!” Trevor cracked a smile and stifled a laugh. “What’s so funny?!”

“Urine trouble.”

Joanna laughed twice, but forced herself to stop. Again, the pressure of laughing proved too much for her to handle right now. “God, Trevor please don’t make me laugh. I’m serious,” she huffed. Her legs trembled constantly, the feeling that she had to go to the bathroom greater than she’d ever felt before.

The minutes passed, Trevor respecting the predicament he put her in and remaining quiet for it. The bases of her palms came to her forehead and her eyes closed, straining through the overwhelming instinct. She swore to herself under her breath in an attempt to ease her struggle.

“Trevor,” she said suddenly, startling her son.

“Y-yeah?”

“Grab that tumbler off the nightstand.” He turned to look where she was pointing, his eyes landing on her tumbler that he somehow hadn’t noticed earlier.

“Uh, I’m gonna have to move. I can’t reach it from here.”

“I’ll help, just be careful.” She bent her knees and planted her feet on the bed for leverage to help scoot herself over. She followed his lead and aimed to minimize relative movement between them, but there were unavoidable mistakes that brought forth groans from the both of them. 

Eventually, the two had circled around far enough for Trevor stand on the ground and reach the container. “Got it,” he said with a tired huff.

“Be ready with it,” she said. “You’re gonna have to catch what comes out, I can’t hold it when you get loose.”

“Yeah, sure thing. I don’t think it’s gonna be much longer.”

“Fuh-ck… Start pulling then. I have to go now.” Carefully, Trevor pulled his hips back with his feet firmly planted on the floor. His mom grunted as she felt him tugging, each nudge teasing the relief she was so desperate for only to disappoint her with the plug remaining in place. “Trevor, please!”

“I’m trying! Just... hold on, I feel it moving. Ah, fuck, yeah here it comes!” He pulled with one last steady tug, slowly feeling the fat lump of flesh retracting from within his mother’s urethra. Thin sprays of piss sprung out from the small but growing gaps in their seal, like a dam about to burst. Trevor readied his mom’s drinking cup underneath them.

“Angh, yes! So close... please!” Joanna begged. In what felt like an instant, his knot finally gave way with a wet splorch, and the flood was no longer contained. One part cum and equal parts his and her piss came gushing out of her bladder, not giving him time to pull his cock fully out of her before he was soaked in it. It flicked up as the tip came free, speckling their degenerate concoction up along her body and joining her milk already there.

“Holy fuck, mom!” 

Joanna groaned out a gratuitous sigh of divine relief, a hand pressing down gently on her lower belly to aid the drain. Her legs slowly stopped quivering, one of her most base instincts finally satisfied. And save for some of the initial torrent, Trevor had managed to capture it all in her oversized mug. She lay moaning there, convinced she’d just had a second orgasm in the middle of that, but she couldn’t be sure.

Trevor set the mug down on the nightstand and went to grab a towel for the floor, letting her rest on the bed. He tossed it down and let it soak up the puddle and was about to rejoin her before she gave an instruction.

“Grab my phone and take a picture,” she said, still slightly out of breath. “I need to see the damage.”

“It’s not that bad, but yeah,” he said. She parted her lips for him and the phone announced its operation with a fake shutter sound, then he turned it around to show her. Her urethra was notably gaped now, even more so than when she’d done this with Harrison. 

“God, you broke me,” she said, both praising and admonishing him for it. She sent the picture to her husband with the text “Look what your son did to me!” attached. With a grunt, she sat herself up, a little more leaking out from her now that gravity had more control, and milk dribbled down from her nipples along with it.

“Sorry, got a little carried away.” Joanna chuckled, then grabbed her tumbler off the nightstand and looked down into it. The turbulence had frothed up some of his cum, but left other clumps floating and unmixed in the urine. She swirled it around with a smile, then took it to her lips for a few gulps. Trevor’s cock throbbed at the sight.

“Jeez, mom…” She pulled the mug down and looked at him with a grin, obviously holding it in her mouth. Without warning, she lunged forward for him, holding the back of his head with her free hand and kissing him deep, forcing the mix into his mouth. Trevor winced and wanted to spit it out, but she forced it in with enough pressure to trip his reflex to swallow before he could consciously reject it.

“Haha! A little payback,” she reveled, drinking some more of her home brew as Trevor gagged. 

“Ugh, god that’s fucking awful! How the hell do you like this?” 

She chuckled. “More for me, then!”
