Melanie, a little five inch tall fairy, was happily fluttering over the city sidewalk. She normally worked as a chef, but today was her day off so she wore an oversized shirt with nothing underneath. The tiny lady had white skin, short pink hair and light blue eyes behind a pair of glasses.

However, her happy little stroll soon stopped as she heard a gasp nearby. Upon looking, she saw a woman in a business suit on her knees and grasping her chest. She looked rather healthy, so Melanie wondered what could possibly be happening to her. The woman panted and coughed, her free hand trying to type on her phone but was too shaky. Melanie looked concerned and flew to the woman.

“Call the hospital as soon as you can..” Melanie softly spoke into the woman's ear before she disappeared, leaving her to look around where the voice could have possibly come from.

Melanie appeared inside of the businesswoman's chest, her glasses gone so they won't get in the way. The fairy blushed deeply as she saw the organs inside, the woman's lungs about as pink as Melanie's hair and her heart nestled inside of its pericardium. However her lungs were trembling as she couldn't get a proper breath, and her heart thrashed and couldn't keep a rhythm. Classic case of a heart attack, as Melanie figured. She flew to the heart, just tall enough to grab onto it.. but the pericardium was proving difficult to keep a grip.

She decided to teleport herself into the sac, ending up pinned between said sac and the failing red pump inside. Melanie at least spotted the culprit; a dark spot in a coronary artery indicated a blood clot. The poor girl must've been overworked into this state, maybe she ended up the pack mule for paperwork in her office job… whatever the matter, the helpful little fairy took action.

Melanie managed to slip her arms and legs around the heart, having a grip around her atria and ventricles. She let out an aroused sigh, to say hearts turned her on was an understatement. If she couldn't get her partner behind heart play during her flings, she at least got them to agree to let her sleep on their heart when they were done. She always preferred her partners to be massive compared to her. Holding someone's heart like this, hearing their valves slap and feeling their blood rush would of course get this fairy so excited… even if the valves in question were flapping aimlessly and the blood sloshed around in the chambers instead. With her slit soaking wet under her shirt and her tiny heart racing like a hummingbird's, Melanie went to action.

She put her toned muscles to work as she squeezed her legs down on the ventricles. Enough squeezing, and the ventricles gave way to push that sloshing blood into the rest of the woman's body. The fairy then started a rhythm as she pushed her hands down on the atria to push more blood down, then her legs again to push the ventricles.

'ba..thump.. ba-thump..' The heart's valves finally made distinct sounds as Melanie forced them to work properly. The fairy panted in exertion.. and lust, as bad as she felt about being turned on from the serious predicament. Though it couldn't be helped much as her position forced her sex to rub against the walls of the organ she was manually pumping.

The woman gasped as she felt just a bit of her energy coming back. The pain from the heart attack still plagued her, but she could breathe and keep her hand steady enough to call 911. She panted, but she managed to keep her voice and words clear as she called for an ambulance at the street she was on.

'ba-thump, ba-thump, ba-thump' The heart stopped thrashing and gave into the rhythm Melanie forced into it, but it wouldn't beat on its own. She stayed close to the organ, moaning a bit as she heard the woman's lungs breathing properly and her voice calling the ambulance. It took a moment before she felt a resistance against her pushes; the heart finally started to beat on its own, steady but somewhat weakened by the attack. She sighed in relief, her work seeming to be done for now. Though she pondered if she should stay and deal with her personal dilemma.. no, she wasn't that depraved. So she simply poofed in front of the woman's face with a smile.

The woman looked up to Melanie, blushing. “Was..huff.. was that you that helped me? It still hurts, but I feel so much better, thank you…” She weakly smiled.

“Anything to help, ma'am~” Melanie smiled sweetly. “I can't just leave someone to suffer like that. You should be just fine. The hospital isn't very far from here, so they should be picking you up soon. And once they get you fixed up… please take it easy. You shouldn't be overworking yourself into a heart attack.”

“I'll try to keep track of my health, thank you..” The woman nodded, keeping herself seated as the ambulance came.

The two waved goodbye before Melanie quickly ducked into an empty alley. She panted and fingered herself into an orgasm before fluttering on her merry way while the woman was taken in the ambulance to get properly treated.
