Jess's three heads snapped to attention, and all six eyes focused on Mary. She'd been sitting on the bed, long furry tail extended behind her, and had clealy been exploring her new body. One hand was at her crotch and the other was exploring one of her middle pair of breasts.
For a moment she looked shocked, then realization spread across her faces and her middle head said, "Mary?"
Mary flexed her powerful form, spreading her wings as she took a step further into the room. She tried to smirk but wasn't sure how it came across on her draconic face. "Like what you see?"
"Wow, oh yes, " said Jess's left head, while the other two gawked. "You're a dragon! And you're... a guy? And you're ripped!"
Mary approached Jess, who was still sitting on the bed, and leaned forward, placing a powerfully muscled and scaled arm to each side of her. She curled her long neck and looked straight into the eyes of Jess's center head. She spread her wings further, wrapping them loosely around the two of them. She said, in a deep growling voice, "That's right. And I'm equipped to do incredible things to you, too."
Jess's transformation had left her incredibly fit but even as a three-headed six-breasted werewolf she felt intimidated. She ran her right head's eyes down Mary's scaled, buff torso. She must have taken a vial to make her incredibly masculine, and if that was the case...
Jess kissed Mary's draconic head, a peck on each cheek courtesy of her left and right heads. She was getting the hang of this! She spoke with her middle head, "Mmm, I get the idea. Just give me one minute, okay?"
Mary took a step back, curious. She folded her wings behind her and straightened, a massive statue of a man-dragon. She could feel her new cock itching for use, and Jess's rows of breasts and taut form were turning her newly male desires on, but it wa only polite. Mary made a show of a courteous bow, her long powerful tail snaking behind her, and said with exaggerated politeness, "Of course."
Jess stood, crossed to the set of vials, and spent a few moments picking one out, then poured half of it down one of her throats. She put it back and returned to Mary.
One head said, "Okay, now let's see..."
"...what happens," said another.
Mary watched as Jess's furry wolf-body shuddered, and she saw all six of Jess's eyes close. A soft rumble of pleasure escaped her throats, and while Mary couldn't quite tell what was happening it apparently felt really good. Of course, that seems to be the norm with these things, so far. She folded her arms across her scaly chest, and suddenly realized something visible WAS happening.
Jess shuddered, and her legs seemed to grow a little longer as her hips widened and her waist narrowed a bit. She felt a mild orgasm ripple through her as something shifted deep inside her -- her vagina growing deeper, she thought. Her chest and tummy grew warm, no, her breasts did, and she felt them expand several cup sizes beyond their already generous size, growing even heavier and fuller. Her necks grew a bit more petits, and she felt her body adjusting to the potion she'd taken.
The vial had said 'Female', and as she hoped it was making every one of her feminine features more pronounced and exaggerated. If Mary was the epitome of a male dragon, she'd be the epitome of a female cerberus in exchange.
Mary watched with growing excitement as her already-very-female friend physique grew even more so. Her six breasts were enormous, her hips flared out into an incredible hourglass shape, and she could only guess what other changes were happening. She might look like a three-headed werewolf, but she was also the hottest thing Mary had ever seen. My god, Mary's male body yearned to touch that.
And then suddenly, it was. Jess pushed herself against Mary's buff scaled form, her six heavy breasts squashing against Mary's chest plates. She ran her fingers down Mary's back, gently scratching the scales with her claws, and in return Mary wrapped her powerful arms and wings around Jess and grinned.
Jess began kissing up and down the sides of Mary's long neck with her outside heads, while the center one purred with a sultry tone, "I want you, now."
