A few hours ago this had been a normal day, thought Jess, as her six sensitive nipples pressed against her very-male and very-dragony friends' body. Her center head looked upwards, into Mary's beautiful golden eyes. Jess was well over six feet tall after her transformation but Mary was massive, probably approaching eight feet, with a thick tail at least that long extending behind.
Jess hugged her friend, feeling the black dragon's wings wrap around her thickly-furred body. It felt protective, and gentle. A new and unusual way to return her hug. It also felt incredibly sexy, she thought in one of her minds. Jess dragged her claws gently down the armor-like scales of Mary's back, running her right hand hand down, down, down and along the side of Mary's tail. The other pulled her tight up against Mary, squashing her many breasts against her friend. She shivered at the pleasure of this, they were very sensitive.
Her left head began kissing up and down Mary's long neck, tasting the musk of her new black scales (His, now, one of her minds reminded!). Her right head followed suit on the other side, while her center head reached upwards and nuzzled Mary's (solitary!) head. They were muzzle to muzzle, and neither of them seemed certain what to do. Mary looked into Jess's red eyes and grinned, and Jess grinned back, excited. They kissed, noses touching, hearts pounding.
As their tongues began to touch, Jess's right head interrupted, with a gentle, "Come on!" She stepped back, taking his hand and leading her friend back to the bed. Mary had no argument, folding his wings behind him and following.
Jess climbed onto the bed, almost crushing her black-furred tail before remembering its presence. She moved it down between her legs and lay on her back, heads propped against the headboard. "I want you," said her center head, while the other two looked down at Mary's package, expectantly.
There was little to see at the moment. Jess could tell his length must be mostly inside, but had no idea what to expect. Her center eyes glanced downward at her own body; the grey streak down her trunk was still present, extending down all her sets of heavy breasts. When she took the 'Female' potion they'd grown even larger, they might be something like a I cup now, and the fur down her chest and belly had grown shorter and finer at the same time. It was like the world's softest velvet covering her six massive boobs, each one capped by a dark puffy nipple that ached to be licked and sucked. Hurry up Mary, thought her left mind.
She spread her legs, making sure her newly improved vagina was accessible. The grey streak stopped higher than that, but the soft velvet fur extended down and around the puffy black lips of her opening. A thought came from her right mind, hoping she was deep enough for an eight-foot-dragon's cock. Her other two minds hoped she was about to find out.
Mary was looking at his friend hungrily. His thick muscles moved underneath the elegant layer of black scales as he climbed onto the bed after his friend. She looked incredible lying there, a supernaturally feminine werewolf with broad shapely hips and so many gorgeous tits. Mary had never been on this side of sex before, had been female until just a few minutes ago, and certainly had never done it with a massive pair of wings and a lengthy tail snaking several feet back. He could feel his cock, hiding in the sheath at the base of his tail. It was rock hard, and he could extend it in moments, but he wanted to build up to that. He wanted to make this first time right. He hoped he could make it good for her.
And so the massive black dragon climbed onto the bed and stopped between Jess's spread legs. He craned his long neck forward, first nuzzling his mate's center head, then moving downward and taking one of her nipples into his mouth. All of them were standing proud, as big as a thumb tip, and he nibbled gently for a moment for giving her top-right nipple a tug. He heard a gasp of pleasure from at least one of her heads, this must be right.
He moved from nipple to nipple, running his coarse tongue over them, then had a realization. He extended his broad wings and planted them on the floor to either side of the bed, freeing his hands even as he leaned over her and began to sink his fingers into her plentiful chest. Her fur was incredibly soft, and she moaned as he carefully squeezed each of her pairs of breasts in turn, his tongue keeping a third breast busy at all times. He sucked on one nipple for extra long, before releasing it and looking up into her eyes. Two heads were transfixed on his attentions, watching happily. He almost laughed to see that the left one was hanging to the side, its tongue lolling, lost in pleasure. Multiple heads, crazy.
Mary spoke for the first time as he told Jess, "Go on, join in."
He saw her center head grin and she replied, "Okay."
At first Jess had been disappointed at the delay, but then Mary's tongue and hands began exploring all her breasts, tugging her nipples, licking and sucking and nibbling, and her minds happily relaxed and enjoyed it. This new body was so much better than her old one, so many places to feel good from. Then he'd instructed her to join in, and who was she to argue?
She slid her hands down her sides and up onto her lowest pair of tits. Jess's palms were bare of fur, and she began massaging her breasts as Mary returned to them as well. Before long she was washed over by a mild orgasm, entirely from the incredible feeling of five breasts being played with at once. She sighed from all three of her heads, and as the feeling dissipated she reached up and grabbed her dragon-mate's head, wrapping her fingers around the horns that extended back. She pulled Mary's head towards her center one, insistent, and said, "I've waited long enough, haven't I?"
Mary laughed, then looked down and buried his muzzle between her breasts, running it up and down her cleavages. Jess's fur was so soft against his scales. Then he looked up and nodded, and leaned forward to kiss her center head.
Then he willed his cock to extend from its hiding place.
Jess's center head was busy exploring her dragon-mate's long rough tongue with her own. The other two heads on the other hand grew more and more excited as Mary's length slid out of its sheath at the base of his massive tail. It wasn't human, but then neither was either of them at this point. It was gently tapered, and though the skin was dark Jess could see that its top edge was covered in a series of bumps, while the bottom side was a series of ridges ringing its surface. Her left and right minds agreed, this would feel incredible inside her.
It was also massive, extending further and further, almost two feet long now. When she took the dose of Female potion she'd felt herself changing inside, her vagina growing deeper and more elastic, she'd thought... but this was a monster of a penis attached to the world's hunkiest dragon. She was worried, and at the same time desperate to feel it.
Jess's center head broke the kiss, and all three of her heads looked into Mary's golden eyes. She wanted to be in control of the situation. "Let me be on top, okay?"
"Worried?" asked Mary. If a draconic muzzle could look amused, this was it.
"I want to take all of it," Jess said from her right head, the others grinning.
They swapped positions. Mary lay on his back, wings outstretched to either side of the bed. His massive tail extended off the end and for many feet further into the floor, and between his legs, at the base of his tail was that magnificent penis, standing tall. Jess climbed on top, moving to straddle Mary's muscular body. She felt Mary's cock pressing up against her belly, and looked down to see it nestled comfortably into the cleavages of her lower two pairs of breasts. God, it was huge, its end tickling the base of her top pair of tits, up on her chest.
She climbed forward, feeling the ridges of Mary's cock as it exited her cleavages and tickled her lower lips as she moved. She leaned forward as she went, dragging her six heavy breasts and engorged nipples along Mary's chest scales. The sensation was wonderful, and she shivered as the pleasure ran up and down her body, noses to tail-tip.
She watched Mary's inhuman cock pop up behind her with one head, while the others looked excitedly into Mary's eyes. She realized her tail was wagging with anticipation, and felt a little embarrassed.
Then she leaned further forward, and reached back, grasping Mary's enormous member, ready to guide it in. She started a little when it moved in her hand, and her two outer heads snapped around to look while her center one looked at Mary in bafflement. The dragon was grinning at her.
"Surprise," he said.
No human could do this, of course. Mary could control his penis to a limited degree, and seeing what Jess was trying to do he commanded it forward, finding her lower lips. She released it and watched with her outer two heads as he teased her opening, running the tip of his massive cock gently up and down her cleft. Her lower lips were puffy and wet, with more of that incredibly soft velvet fur to either side.
Though Jess's fur was still coarse and wolf-like along her sides and back, every inch of her front was silken and wonderful. Mary had almost came when she'd dragged his cock down between two pairs of breasts, the sensitive ridges on his underside being caressed by that incredible coat.
The dragon sighed deeply, enjoying the feeling as he explored the entrance of her pussy with his cock. She seemed to be getting into it too, looking down at him with all three heads. Two of them had their eyes closed and seemed by be lost in the feelings, while the right one began gently planting kisses up and down his long neck, caressing his scales with her nose. Mmm, that was nice, too. He felt her relax and settle her weight, her upper breasts against the base of his neck and the lower pairs on his chest.
Mary had been female until not long ago, and he understood Jess wanted to control the pace. He knew he was big, and she was probably worried about fitting, and he got comfortable as he dipped the tip of his massive length into her, just an inch or two. He stiffened it, and nodded at her. Her turn.
Jess had simply relaxed atop her dragon-mate for couple minutes, enjoying the feeling of her pussy being teased by his (prehensile?) cock. It was like a tongue, almost, exploring her entrance gently, feeling her wetness, teasing her. She closed most of her eyes, feeling so good, thrilled by her own strange body. Then she felt Mary's length begin pushing into her, but not far, and then its movement stopped.
She opened a pair of eyes and understood. She pushed herself back up onto all fours, the shifting of her weight pushing the length a little further in. Mary's inhuman cock was massive, two feet long, but its end was gently tapered and so far it fit easily. She kissed her dragon-mate with all three heads, then rocked back a few inches more. Her vagina's outer lips spread, and she felt them close around first one set of Mary's ridges, then another. The third ridge was a little tighter, and she stopped there.
Rolling her hips forward and back a little, she felt the third ridge pop past her entrance. Mmm, and there were little bumps on the top side too. She craned her left-hand neck around to look, she had about a third of him inside her now. She rocked forward and back, feeling those inches move back and forth within her, her inner walls stretching. She looked back into her lover's eyes with all of her own, and asked, "How's that?"
"Like heaven surrounded by velvet", he said.
She grinned three times. Awesome. Then she leaned back and let Mary's length sink further into her. It was getting thicker and thicker, and she could see that at its base it was nearly as big around as her forearm. And two feet long! She couldn't get that incredible length out of her mind, it seemed impossible.
She had him more than halfway in when she began feeling pain, and stopped. He was so deep inside her, more than a foot of black dragon cock, and the ridges and bumps felt incredible, but it had nowhere else to go. Inside her, she felt the first few inches move a little, like a tentacle exploring her depths. Then it pulled out a couple inches and pushed back in. Her left and right minds thrilled at the feeling, while her center head giggled and smiled at the questioning expression on her partner's draconic face. Oh yes, it felt interesting and different, and she trusted her friend.
Jess settled down again, squashing all her breasts against her partner's muscular body as she relaxed. Ten inches of him still remained outside, but she wanted to get used to things first.
Mary took the hint and gently began controlling his cock, moving it out a few inches then back in. He rippled it back and forth a little, watching her faces to see her reaction. She sighed and began running her hands up and down his sides. That seems good.
The pair of them fell into a gentle rhythm, with Mary carefully exploring Jess's depths, but not going further than she'd left off. He found he could sort of 'swirl' his penis inside her, and the feeling against his member's bumps was so incredible he had to stop for a long minute. It was too soon to climax... but god this felt so good, especially when her inner muscles seemed to almost gently pull him deeper in. He ran his hands through the coarse fur of her back, enjoying the feeling of her body against his. She ran one hand along the stretched scales of his inner wing, exploring his own strange features.
Then she planted her hands again and lifted herself off his chest, and nodded with all three heads. Time to go further. If she could.
Some of Mary's length made a soft slurping sound as it pulled out of Jess, as she raised herself. Wow, they had gotten pretty relaxed there hadn't they? She'd spent those long minutes trying to understand her new pussy, which she was convinced had changed via the Female potion. She'd found she could control her inner muscles much more than she'd previously been able to, and wondered if this was similar to how Mary could control that wonderful cock of his. Was this a property of the gender potions?
No matter, she thought she understood now. She tilted back, her heavy breasts hanging beneath her now as she was on all fours. Mary's length disappeared into her once again, until she reached the point where it was uncomfortable again. Mary was looking at her questioningly, but Jess's only response was to grin with all three faces and ripple her inner pussy as a sort of 'welcome back'.
Then she leaned further back, and felt another few of Mary's ridges slip past her outer lips. She relaxed her inner walls, asking them to allow this massive intruder, and magically discovered that they did! The uncomfortable tightness slowly dissipated, and looking back with her right head she saw that almost 18 inches of Mary's incredible cock were inside. Jess let out a long sigh from all three mouths, feeling a sort of zen as she pushed back even further.
Mary's ridges were really stretching her entrance now, the bottom part of that magnificent cock being as big around as her forearm. But Jess was more elastic than she ever could've hoped, both inside and out. Once she'd found it in her mind, the magic seemed to let her accept almost any size, like she was bigger on the inside. I wonder if there even is a limit, she wondered.
Her outer lips were grasping Mary's length tightly enough now that each ridge and bump was affecting her clit, so every tiny motion felt incredible. She closed all her eyes, and emitted an audible rumble deep in her throats as she felt the last few inches of Mary's magnificent penis disappear into her own magnificent pussy. Finally, she felt her lower lips meet the scales of Mary's sheath. She felt the ridges and bumps of its two-foot length inside her, every detail of it against her inner walls. Her inner walls began pulsing up and down his length, massaging it, milking it for every bit of pleasure she could manage.
Jess raised herself up a couple inches, then lowered back down, feeling those ridges and bumps against her clit. She went further, allowing almost ten inches of it to exit her before lowering back down. Mary began reaching up and caressing her rows of breasts as she began fucking him in earnest. She saw the grin on his draconic muzzle and leaned forward, kissing both sides of his head with her own outer heads. Her center head she simply leaned back, eyes closed, enjoying the feeling with her primary mind.
Up and down, in and out, her inner walls stretching and rippling around the increasingly welcome intruder. She felt hands on her breasts, and realized one of them was her own. She felt a tongue on one of her upper nipples. Inside her, Mary's cock was moving in small gentle motions, every time she lowered herself onto his length it was a little different. Every time it was incredible, to have something so deep and that felt so good, her outer lips stretching and releasing, her clit dragging up and down along those wonderful bumps along the top of his cock, this was incredible.
She settled back down, taking his whole length once again, and felt his tongue on another of her nipples, and felt his two hands squeezing two others, and her own hand on yet a fourth, and remembered the feeling from earlier when they'd started. She leaned further forward, all six nipples touching against her dragon-mate's scaled chest. She gripped his two-foot length tightly with her inner muscles and pulled herself forward, then back, and almost passed out from the pleasure. Her breasts were so sensitive, and she had two feet of pussy being stimulated, and her clit against those wonderful bumps, and now Mary's hands were exploring her fur, and she kissed the sides of his long neck with her outer heads, and her center head explored his muzzle with her own, and she moved back and forth, and she felt Mary's penis tense up and begin twitching, and a sudden warm feeling deep inside herself, and then the world exploded in her minds and she reached the most intense orgasm she'd ever felt. It was almost a dream as her entire body shuddered, and all three of her minds struggled to stay conscious, and god, it was amazing.
Mary's massive draconic body shuddered with pleasure. Jess had clearly found her rhythm, all her eyes were closed, she was enjoying every inch of Mary's cock, and those sensitive bumps were only getting more sensitive. Mary tried to hold out as long as he could, but Jess's pussy felt like heaven. And then she'd begun dragging her nipples against Mary's chest and belly, and Mary felt that silky fur against his scales, felt two heads exploring his lengthy neck again, and felt Jess massaging his length inside, and it was too much.
This was Mary's first male orgasm, and he felt his internal balls churn and what must have been a pint of cum travel the considerable length of his cock. He couldn't control it anymore, not now, and the feeling ripped through his body as he filled Jess's pussy with his seed. He'd been running his hands through her fur and just after he came he felt her begin to tremble, and knew she must be cumming as well. He saw her three heads sort of relax against him, and her body go limp against his, and he held her tightly as he felt her muscles tremble and shudder, both inside and out. He realized her tail was wagging.
Mary closed his own eyes and leaned his horned head back against the pillows and relaxed, deciding to let Jess recover at her own pace.
Later, Jess's right head blinked its eyes and slowly, dreamily looked around. Her other two minds seemed asleep. She was lying atop Mary, her six breasts squashed uncomfortably between them. They felt a bit sore, she must've been lying like this for a while. Actually, was she still feeling... ?
She looked back and saw that Mary's two-foot length was still inside her. Mary seemed asleep but she swore she could feel its length twitch just a bit inside her. It hadn't been so long ago that she was worried his whole cock wouldn't fit, but now here she was comfortably asleep with that whole monster buried in her cunt.
She pushed herself back up onto all fours, her various breasts shifting and hanging below her. Mary's cock wasn't fully erect at this point but it wasn't soft either, and her other two heads seemed to slowly awaken as it slipped ridge-by-ridge out of her stretched-out pussy. Mmm, it still felt so good when it moved within her.
Mary stirred as well, curving that long neck down to nuzzle the side of Jess's center head as it awoke. Kissing was a little strange when your head was shaped like theirs now were, but they made do. He craned his head down to look below Jess, past those rows of velvet tits to where his cock was still partly inside her. Taking control of it, he gently extracted the last several inches, seeing her shiver a bit at the feeling.
As he willed it to return to the sheath at the base of his tail, he asked, "Is that a good shiver?"
"Oh yes. You feel so good inside me." Then she leaned forward and dragged her six nipples across his chest and belly scales again, grinning with all three heads. "And outside, too."
"Good."
Jess relocated to beside him on the bed, and he shifted to lie on his side, moving his wings to behind him. They draped off the side of the bed and covered a considerable portion of the floor. At the same time he pulled his lengthy tail up onto the mattress, curling it forward and around and behind where Jess lay. It was strange having a body so long.
Jess was lying on her side, facing him. She had begun to realize that this position wasn't so great with three heads, and spent a minute trying to get them all comfortable. Maybe she needed to buy some more pillows for this...
Mary's neck was more than a foot long, and he had horns, and he was having a little trouble himself. New bodies, things to learn. The two of them grinned at each other, a dragon on one side and three wolves on the other. Mary spoke first, "Did I do okay? I wasn't always sure what was right."
Jess's nearest head kissed the end of Mary's muzzle. "You did great. You felt great. And I want to do it more."
"Already?"
"Well, maybe after a nap. And we still have all these vials to try... but at the same time I love being what I am, now. There's so much... more of me."
Mary's long tail was already curled up behind Jess, and he moved it to caress the coarse fur of her back, running it down her spine to where her tail sprouted. He wrapped the narrow end of his tail around hers. He said, "There's still things to try with these bodies, and I like this one. And it's different being a guy. And hell, I haven't tried flying yet."
Jess felt Mary's several-foot-long lizardlike tail touch her own and remembered wondering if the magic made her bigger on the inside. The thought excited her. "I'll try anything."
