Monica wakes up changed.

Addie played with her mother's hair, dragging her fingers through it gently. Weren't the auburn locks thicker than before? She could have sworn that... Suddenly, Monica groaned in her sleep, face contorting in a mask of exertion. A wave of small tics and muscle spasms began in her neck and ran down her shoulders, arms, over her pecs, back and abs, the twitching making her enlarged tits shake and quiver. The spasms ran down her legs as well, Monica's toes curling and cramping involuntarily. Once the twitches had reached her toes and fingers, it reversed direction and ran back up her body. As the wave ran backwards over Monica's thighs, Addie realized what was happening.

Her mother had always been fit and toned, keeping up a regular yoga regimen, but now, with every ripple passing over her body, her muscle fibers seemed to multiply, Monica's body quickly going from toned to ripped, a thin sheen of sweat covering her skin. Her strained groans scared Addie a bit, and she moved to support Monica's head on her soft, expansive thighs. Looking at her lover's changing body with a mix of worry and arousal, Addie marveled at how Monica's hips and thighs seemed to expand, muscles bulging below a healthy layer of fat. The little mound on her belly that Monica had never seemed to be able to get rid of however melted away, making room for a defined six-pack. Her soft, jiggly tits appeared to rise as the pectorals below them swelled from barely there to substantial, while Monica's arms grew more and more muscular, almost tripling in size.

As Adam, Addie had never really cared for muscles on other people, not on women and certainly not on men, but now, as she saw Monica becoming ripped right before her eyes, her throat felt dry and her panties slightly damp. She imagined being embraced by her mother's strong arms, resting her head on the soft boobs, feeling the bulging pecs below them... As Addie's thoughts continued down a more racy path, remembering the more complicated positions she had seen in porn that required a strong partner, a fierce blush spread on her face and her pussy twitched involuntarily.

Finally, the spasms subsided, and Monica's face and breathing relaxed, although Addie could only infer the former from how she felt her mother's facial muscles relaxing under her fingers - her tits were simply to large for her to actually Monica's face. How she hadn't woken up during the ordeal, Addie didn't know. She kept caressing her mother's head in her lap, watching how the sweat across Monica's dried, cooling her down and making her shiver. Monica scrunched up her face in discomfort and opened her eyes, looking up at Addie's underboob.

"Mmmmh, what a view to wake up to," Monica mused, only to quickly notice how her whole body felt sore, "God, I feel as if I just ran a marathon or something."

"Uhm, about that, mom," Addie said, "you might want to check yourself out..."

Reluctantly getting up from her daughter's soft, warm, oh so inviting lap, Monica groused: "Why, what do you-- OH MY GOD!"

Eyes wide, Monica let her hands run over her changed body, muscles bulging as she twisted and contorted to get a good look at herself, inadvertently giving Addie a great show of rippling muscles and bouncing tits. Her daughter gaped, all but drooling over Monica's transformed body, so mesmerized that she almost missed one very important change right between her mother's legs.

"Oh my god, mom! Your balls!" Addie exclaimed, pointing with one hand, the other in front of her mouth, fingers splayed.

Slightly apprehensive, Monica bent over and moved one hand down to her scrotum, grabbing her nuts and realized how she had been able to pump her darling daughter full of so much cum - her bulbous cum factories had swollen to the size of her fists, pulling her sack down heavily.

"Holy shit," Monica breathed, looking at Addie, still bent over and a giddy smile on her face, almost as wide as the one on her daughter's, "How is this even possible?!"

"Who cares, you look amazing!" Addie squealed, barely containing her excitement, and jumped on her mother's lap, both legs to one side, her arms wrapped around Monica's neck. The older woman moved her arms just in time to return the hug, gazing into Addie's eyes lovingly.

"I'm glad you like it," Monica said, worry apparent in her voice, "although I'm certainly less soft than before..."

Addie decided to alleviate those by peppering her mother with kisses on her cheeks and lips.

"Don't worry *smooch* you're still *kiss* plenty soft... *smooooch*," Addie whispered, smiling as she felt her mother's hardon press into her butt, "And hard in all the right places."

With that, she pulled Monica into a deep, hungry kiss, their tongues questing into each other's mouth, Monica grabbing her daughter's heaving left breast and caressing the engorged nipple through the fabric, making Addie moan, muffled by their lips locking together.
