Get cleaned. Again.

Cleaning her cleavages was luckily not much trouble, just quickly running the showerwater over Keira's front and then soaking another of her towels as she dried herself off. This time, the cerberus was more careful wringing out the towel, hanging it over the edge of the bathtub to let it dry. So far, so easy. Less easy was the fact that Keira had time to think about what had happened one floor below as she got cleaned and dried, all three heads pensive and silent. Until, that is, the right head finally spoke up.

"You know, Debbie has a pretty great cock."

"Yeah, she d-- uhm, I mean, what?" The left head only just caught herself. "Why'd you bring that up?"

"Oh, don't pretend you weren't thinking about it." Rolling her eyes, the right head chuckled. "It felt nice when she put it between our tits, right? It's pretty big, even compared to our body, and it has a nice shape."

"Okay, I'll admit it, Debbie's dick is pretty nice, and I did wonder how it would feel inside us. But if we keep thinking about this..."

"Uh, girls?" The middle head interjected, looking down Keira's body as she put her hands against her hips. "Too late, kinda."

Indeed, there was a distinct throbbing in Keira's loins, even as her nipples stiffened. The other two heads lowered their muzzles to take a look at Keira's sheath, and saw the red tip of her dick begin to push out.

"Okay, now what? Do we wait for it to go down, orrrr~..." Throwing a glance first to the left head and then to the right, the middle head tried to feign innocence.

"I mean, we could..." The left head mused, but the fact that Keira's right hand was slowly creeping towards her slowly bulging sheath and her left was already playing with her left middle tit betrayed the fact that all three heads were of one mind.

"But that would be boring, right?" Keira's right head grinned as the cerberus began to rub her crotch, fingers parted around her swelling rod. "I mean, our cock is so big, and we've only used it once so far."

"Nnffh~..." As the fur of her fingers brushed over the cerberus's pulsing shaft, the middle head bit her lip, fangs pressing against her lower jaw. "True, but as good as it feels--ooh! As good as it feels, we need to be careful, or--unnh~!"

"...Or we'll never leave the room again," the left head finished as Keira squeezed her upper right breast, pinching the nipple gently as breastflesh and soft fur bulged out between her fingers

"Would that really be so bad?" Moaning softly, the right head closed her eyes appreciatively as rising lust made Keira's nipples harden, shaft stretching her sheath gently as it grew ever more erect. "Stay in, just play with ourselves and--aanh~, maybe with Debbie?"

"Hey, just because we're now a, like, 8 foot tall wolf monster with three heads doesn't mean we cannnnh~ just become some perverted shut-in..."

"Tru--uh!" Keira's massive dog cock lurched as it stiffened, and the cerberus wrapped her right hand around it, slowly stroking it towards full hardness. "God, that thing feels great..."

"Oh yeaahh~..." Middle head lolling back, tongue lolling sideways from her muzzle as she panted, Keira kept fondling her largest set of breasts while her knot popped free of her sheath, shaft finally fully erect. "I so get why so many guys are obsessed with their dicks..."

"Or with having them sucked--wait a minute." The right head suddenly had a lust-crazed gleam in her eyes, throwing a glance towards Keira's other two heads. "You know what? I've seen eggplants that are smaller than that thing. I wanna try some--mmh~..."

"God, that's such a dumb idea..." Mumbled the left head as Keira sat down on the floor, leaning against the tiled wall behind her. "It sounds great, let's..."

The cerberus' middle head didn't waste time talking, instead diving down towards the pointy tip of her cock, giving it a tentative lick as her muzzle was sandwiched between her uppermost breasts. Keira shuddered lustfully, the sensation of her hot, broad tongue making her shaft twitch lewdly as the cerberus groaned, left and right heads bending down to lick the sides of her throbbing member, pressing against the outsides of Keira's top breasts. Hands now free, Keira began to massage and squeeze her middle and lower row of breasts, gently rubbing and pulling her nipples in a more than fruitful effort to heighten her arousal.

"Unnh~..." As the broad tongues of her left and right heads lapped over the swollen sides of Keira's fat rod, the middle head groaned lustfully, hard nipples digging into soft pawpads as the cerberus squeezed her middle breasts gently. "Oooh, that's gooood~..."

Diving back in, Keira's middle head opened her maw wide to welcome the pointed tip of her cock inside, tongue slurping against the upper side of her enormous member as the cerberus struggled to fit even the upper half in. Of course, that left more than enough red, sensitive shaft unattended for Keira's outer heads to lick and nuzzle and kiss, every touch sending tingles and shocks of pleasure through the throbbing rod. And with three heads, the cerberus had both hands free for other fun parts of her anatomy - although with how erect Keira was from three tongues and a hot maw against her enormous schlong, she wouldn't have needed her hands in any case.

"Mgh, mgh, mgh!" Hips bucking into her middle throat, Keira gagged around her thick shaft, tail wacking against the floor as the middle head's eyes rolled up in their sockets. "Glgh, grgh!"

"Holy heck, you're taking that thing like a champ!" The right head marveled at the way the middle one slobbered all over Keira's knob, breathing more heavily as the middle head's throat was well and truly plugged. "Oh god, that feels amazing! Yeah, keep sucking our dick like that!"

"Got to give it to you, hun, that was an incredible idea--ooh yesss~!" Panting excitedly, the eyes of Keira's left head glazed over before she dove back down and against her knot, licking over the swollen, pulsing bulb languidly while the right head slurped along the parts of the cerberus' shaft neither of the other heads could reach.

Simply masturbating had already been great, but all the saliva making Keira's shaft slippery and the hot tightness of her throat elevated this far beyond even her very first experience with her massive dog dick. The dizziness enveloping all three of her heads had nothing to do with lack of air, sheer lust making it hard to think as Keira pawed her tits, pushing them together and against her heads and shaft for that little bit of extra stimulation that had the cerberus' heart hammering in her throats, lustful growls emanating from all three as she kept fucking her middle throat.

"Glgh, glugh, ghg!" Even gagging on her length, Keira couldn't fit even half of her shaft inside hre muzzle, let alone reach her knot. Precum had begun to bubble from her pointed glans, every drop of the salty fluid guzzled down eagerly. "Ulgh, ghlrgh!"

"Oh god, keep going, don't stooop~!" Moaning encouragements for the middle head, Keira's right head peppered her shaft with a line of sloppy kisses, adding to the slippery mix of pre and spit coating the cerberus' enormous red rocket. "Fuck, it feels sooo good!"

"Languh--Language--oooh heck!" The left head's complaint was cut short as the right one sucked on her massively swollen knot, making the cerberus' member strain and squirt out a glob of pre that oozed back down Keira's length. "Oh--oh--oh god!"

Keira's hips bucked uncontrollably, lust long since overtaken rationality, ears twitching as all three heads chased after the final peak in unison, frenziedly licking and sucking and gagging on the cerberus' cock. Flicking two of her nipples, Keira was rewarded with another thick spurt of pre into her middle maw, throat overwhelmed by the sheer volume. But the additional lube allowed the cerberus to properly thrust upwards, pumping her oversized shaft into the muzzle of her middle head as she did her best to stimulate her cock with tongue and lips.

"Oh--oh no, it's getting even harder, I thing weeee~..." Eyes rolling up, tongue hanging out sideways, the right head yipped lustfully with a dopey smile on her muzzle, hips ramming the cerberus' monstrous cock deep into the middle head's throat. "Hah-hah-haooOOOOOH!"

A twofold explosion of white ravaged Keira's senses - unbearable pleasure wiped away all thoughts, all sense of self, and a deluge of cum blasted into her middle throat from the cerberus' pulsing cock. Neither head could even think of swallowing, particularly not Keira's middle one, and massive globs of cum oozed out of her maw and down her gargantuan, straining shaft to instinctively be slurped up by the cerberus' left and right heads, the sensation of their hot tongues lapping over the trembling member making Keira shudder lustfully.

All her washin up was rendered moot as cum ran down her front, over the swell of her breasts, her abs hidden under her fur, over her hips and down onto the tiled floor, matting the cerberus' rich pelt with her own swimmers again. Writhing and jerking, Keira bucked her hips helplessly as shock after shock of pleasure raced through her with every new rope of cum exploding from her tip, muffled and less than muffled howls of pleasure echoing through Keira's apartment as her climax went on and on.

Finally, Keira's cum was utterly spent, just as the cerberus herself, and she leaned back and pulled her twitching, lurching member out of her middle throat, all three heads panting with exertion and sheer lust. Every last one of her muscles felt weak and loose, satisfaction relaxing her better than any massage ever could.

"Wow, I... heck."

"Taking the words... out of my mouth, hun."

"I... I'd never have thought I would like the taste of my own cum." Incredulous, the middle head stared at her slowly deflating cum cannon, licking her chops to clean up some of the cum sticking there. "Or that I would be able to suck my own dick. Heck, even that I'd have one!"

"Worth having to take another shower?"

"Yep!" Left and middle head nodded enthusiastically as they answered the right head's question.
