"Why do I have to wear a sports bra?" Rosa questioned her girlfriend. "And why are we standing? Wouldn't it be better and more comfortable if we were in bed? You know, with me laying on it?"

"Just trust me." Elouise answered while she retrieved a purple jar.

The brunette had promised Rosa a massage. She loved the idea. It was quite romantic, and would be great foreplay. Because she knew there was no way Elouise would spend more than five minutes with her hands on the dark-haired beauty without getting all hot and bothered.

But then, she urged Rosa to be half-naked and stand by the bed. The odd request dimmed some of the flames since she expected to be completely naked and on the bed while receiving the massage, but she humored her lover anyway. A free massage was still a free massage.

"Okay..."

The massage oil was nearly transparent. Elouise scooped some, then spread it on her hands as she made her way behind Rosa.

"Ready?" The brunette asked. Her gooey hands hovered over her partner's chest.

"I guess? I just don't understand how this massage is going to spice things-ah!" Rosa yelped as the cold cream came in contact with her skin. Elouise had swiftly slid her hands under the bands of the sports bra and fondled whatever soft flesh she could find. Which wasn't much. Hence why she wore such a sporty garment and not some fancy, sexy lingerie. She never needed the support.

Elouise chuckled, and Rosa slapped her girlfriend's hip in retaliation. Now that she got used to the coldness of the cream, she could properly enjoy her girlfriend's ministrations as Elouise dutifully slathered her breasts.

And only her breasts.

"Aren't you going to-"

"Shush. Just relax."

Rosa sighed. She tried to follow her lover's suggestion, but Elouise was only fondling her. It felt good, yes. But she expected more of this massage. More of her being lathered with cream at the very least.

Maybe if she was laying in bed with Elouise straddling her while the brunette worked on her breasts... Their eyes locked, the tension slowly rising as they got into the mood... Then maybe...

"Haaaah..." A moan slipped from Rosa's lips. Yes, the massage was quite nice, the scenario in her head was enticing, but those weren't enough for such a sound to slip out of her lips.

No.

Her chest. Her chest was on fire.

"Hmm... Ah! Elouise!" Rosa gasped, stumbling back against her partner as an intense, overwhelming heat pulsed in her breasts, washing over the rest of her body in smaller waves. Pressure built within her tiny mounds.

"Feels good, doesn't it?" Elouise whispered in Rosa's ears. Her lips gently brushed Rosa's lobes, making the blonde wish she nibbled at them as well, but Elouise always loved to tease her. She loved it so much, she squeezed Rosa's breasts even harder.

Then Rosa froze as she felt something pushing against her partner's palms. And as it pushed and surged, Elouise groped her harder and harder.

She looked down and couldn't believe her eyes. Flesh bulged from between her partner's fingers, and out of her sports bra. Cleavage. For the first time in her whole life, she had cleavage.

"H-how? Hmm!" Elouise interrupted Rosa's questioning by pinching a nipple, bringing the excitement that the surprise evicted back with a vengeance.

"Don't question it." Elouise whispered again. This time she nibbled Rosa's ears and brought forth a delightful moan out of her lover. The brunette had a hard time massaging Rosa's breasts as the growing masses pressed her hands against the stretching, but tight and compressive fabric of the sports bra. Though it didn't mean she didn't try. "Just enjoy it."

"It's... too tight..." Indeed. Rosa's sports bra dug into her shoulders and into her ribs. The garment wasn't made to uphold the handfuls she grew and insisted on inching outward, taxing them both. With no room to grow, her flesh spilled everywhere. Cleavage, underboob, sideboob, her fattening tits bubbled out of every nook and corner they could find. "Ngh..."

"An amazing view, isn't it?" Elouise nestled her chin on Rosa's shoulders. "Do you think your cleavage will reach your chin?" She squeezed the swelling mounds slightly, propping them up towards Rosa's whimpering face. She didn't have much room for anything more elaborate than that. "Or do you think your tits will burst out of their confinement first?"

Seams began to pop. Flesh oozed out. The elastic strained, turning translucent as it stretched to its breaking point. Then its whole front exploded, unable to match Rosa's unstoppable growth.

The couple just stood there. Watching as the expanding tits bounced and swayed, celebrating their hard earned freedom.

Rosa tilted forward. The weight finally caught up to her as they settled heavily against her stomach.

But her girlfriend was there to hold it for her.

Elouise mashed her hands against the burgeoning softness, digging her fingers into the pliable flesh. She squeezed the heaving behemoths against Rosa's torso, lifted them up and then dropped, relishing in the view of such massive breasts yielding to gravity.

"Oh, God! Elouise! Aaahn!" Rosa's knees trembled. She placed more of her weight on her lover. She couldn't trust herself to keep standing. She rubbed her thighs together, feeling herself soak her panties. "Don't stop... please! Don't!"

"And why should I?" Elouise pinched and pulled plump strawberry-sized nipples, making her girlfriend cry animalistically. "Oh, how I love the sounds you make, Rosa."

Rosa didn't respond. Everything felt fuzzy, warm, static. She felt heavy, light. She was melting on Elouise's embrace, but she was so big, so huge, so much. How could she melt when there was so much of her and every second that passed there was more and more and more of her for Elouise to play with? She was becoming more tit than woman. She was just a pair of massive, heaving, supple tits. She was...

"Aaaaaaaaanh!" Rosa's legs buckled, sending them both tumbling to the ground. She didn't register the pain of the fall. She was too busy being assaulted by heavenly pleasure as the most incredible orgasm washed over her.

"Told ya to trust me." Elouise said, admiring the rise and fall of her partner's chest as Rosa panted.

The dark-haired woman's tits were a sight to behold. Even as they splayed to the sides, their curves rose far beyond anything they have ever seen on a person.

Elouise hugged them, corralling the heavy mounds on Rosa's torso, watching them bulge as she pressed her arms on their softness. Rosa sighed contently. A gentle murmur thanks to the tiny wave of pleasure that having her breasts being squished caused.

"Please, tell me there's more cream on that jar."
