Heather realizes something is wrong too late

--Props to Zheng for having great art and indirectly inspiring this whole branch--

Heather was too hot.

She thought it was just nerves at first. She had faced off against two Infected and gotten away, surely an elevated body temperature was normal after that. But as she continued to sneak through the largely quiet neighborhood, she didn't cool down. In actuality, she only felt hotter.

To make matters worse, the moans and screams of lust that echoed through the otherwise quiet night sent bolts of desire through her. It wasn't very often, most of the Infected had seemed to have gone somewhere else, but any time one of those sounds reached her ears, she could barely keep herself from stumbling to the ground. Instead, she **** herself to keep walking, single-minded in her focus to get back to her father's bunker, to safety.

Eventually, it wasn't just Heather's warm body that was distracting her. Her legs and back ached terribly, but she attributed the pains to being hunched over and dashing from hiding place to hiding place. Angles didn't seem quite right, maybe she was feverish. Her balance was off too, she should really get checked out by her mother. It was extremely convenient to have a trained doctor in the house sometimes. Maybe she should see if she gained some weight recently too, her clothes seemed tight all over.

A lusty whimper, much closer than any before, nearly sent her to the ground again, her uneven balance not helping. Heather barely managed to catch herself against the trunk of a tree, leaning heavily against it. She must have fallen further than she thought, one of her breasts was squishing against her arm and the tree. It was sensitive too, much more than it ever had been before. She was no stranger to sex, but she had never been this sensitive before. Pushing the thought down, she jerked herself upright and continued on.

Finally, she was on her block, walking through backyards to reach the bunker entrance. Well, she tried to walk, but those same whimpers continued to trip her up, the noises continually becoming more ****. Heather through she would have left whoever was making those sounds behind long ago, but once again ignored the thought in favor of moving forward.

Luckily, the ache in her bones had stopped, but now her entire body was tingling and trembling, and it was getting harder to ignore. A strange feeling between her thighs was becoming more and more pronounced, forcing her to take smaller steps to avoid the feeling. The light brush of her purple skirt felt wrong too, much higher on her thighs than it should be. All of which paled in comparison to the unrelenting pressure on her chest. It felt like her shirt had tightened considerably, leaving her barely able to breathe properly.

Heather could see the entrance to the bunker when her need to breathe got the better of her focus. She wasn't going to make it without being able to fill her lungs. Her hand rose to her chest to try and stretch her shirt out a little when she ran into something. Two somethings. Two large, heavy, fleshy, squishy somethings.

For the first time since she started walking home, she looked down. Gone were her sizable but saggy breasts. Jutting out of her chest were two enormous tits, the mounds stretching parts of her shirt to near transparency, especially around her nipples, which stood out firmly from her peaks. Her bra had failed to constrain the bouncy globes leaving the hypersensitive tips to rub against the rough fabric covering them. Experimentally, she poked at one of the erect nubs, her mind still not quite caught up with her changed body.

Without warning or fanfare, she came, and came hard. Or rather, quite expectedly, as she had been ignoring all the warnings. Her enlarged and sensitized tits bounced and shook as she thrust them out. Her eyes closed involuntarily, no longer able to stay open through the storm of pleasure, her tongue lolling out of her mouth for much the same reason.

Despite having not seen it, Heather could feel her much larger ass quaking and clenching through her orgasm, the flesh of her firm butt melding into equally thick thighs. Her pussy spasmed and squirted, drenching her panties and luscious thighs with her girl cum.

Heather, in an exceptionally brief moment of clarity, thought her peak couldn't reach any higher, only to be proven wrong instants later. A feeling entirely foreign to her rushed through her from her pelvis. An incredible sensation of tightening and squeezing, followed by powerful pulsing. Heather whimpered again, finally recognizing herself as their source, and tensed her whole body. The feeling of something shooting out of her, like squirting but better, sent a wave of jiggling through her bouncy body. The spurting feeling continued, each blast as blissful as the next, and Heather could do nothing but ride it out, her eyes screwed shut and tongue hanging out of her mouth.

It was only after her orgasm stopped that she had the nerve to open her eyes, the green orbs looking past her prodigious cleavage to look at the thick, oozing, dripping penis fixed to her crotch. A tiny bit of exploration revealed two heavy testicles hanging in front of her pussy, which she thankfully still possessed. She was **** to stop her exploration there, the light touches to her new balls and cunt arousing her far too much, especially since she had just cum, and done so rather explosively if the jets of seed spread across the grass in front of her were any indication.

Her dick had barely deflated, she realized, the huge shaft still largely standing at attention. She knew she could cum again if she wanted to, and a small part of her did. Already entirely overwhelmed, Heather pushed that desire down as best she could, at least for the moment. She had other things to worry about first. Slowly rising to her new full height of 6 feet, she unsteadily tottered towards the bunker entrance, hoping her father would still let her in.
