Dash looked down at herself, she was soaked, her mound was drenched as was her tail and snout. "deactivate" She managed to whisper the command, her throat sore from how loud she had been. The snake didn't move. "deactivate" She tried again.

The snake inside the mare squirmed a little, tingling her nerves again and driving a moan from her mouth.

"Oh please deactivate!" Dash cried it out as she came hard again, her body trembling as the snake withdrew and curled up beside her. The wood had odd new patterns in it and smelled… well, it smelled of the musk that she had soaked herself in. It didn't curl up and stop like the command should have made it, instead it nestled in against the pegasus' neck. She couldn't stop herself, still reeling from her most recent climax, Dash began to lick the snake that she had suddenly taken quite a liking to.

The train had been stopped a while, Vinyl was just getting into the latest beat of one of her DJ friends, who they both played up as a vicious rivalry, had released. It sang through her and made her heart join the beat, it felt like all of her body was bouncing along with the music when one of her earphones was lifted up. "The train has stopped, we are here."

The green mare's words crashed onto Vinyl's awesome buzz she had going and she gave a frown, pulling her earphones down. "Octavia is here?" The question got a nod and a forced smile from Mellon. "Then I want to see her."

Mellon was relieved, this was more like it. "Come along then, oh, look at the time, well, we can get something to eat when we arrive." Her own song was growing as they got off the train, the nearness to the rest of the ponies singing it made it swell and remind her of the perfect purpose that it imparted.

Vinyl really didn't like this, something seemed very wrong with the pony who had led her here, and as she neared what looked like the Everfree forest she slowed her steps. "Deep breath V, she is the best thing that happened to you, you can't give her up." Her own words strengthened the mare and she smiled and started trotting forward.

A mare with green fur and red, dread-locked mane moved up beside Vinyl. "Hey there sister of song, you should turn back, the gnarly beat ahead is unstoppable."

"I can't, my marefriend is here." It felt easy to talk to the mare and Vinyl found herself liking her. "Wait, what beat? I can't hear anything."

"Shh, come with me." Tree Hugger guided Vinyl away and out of the sight of Mellon Dew. "This is my friend, like, treat her nicely."

Vinyl had an odd sensation that the mare was either talking to her or the huge tree in front of her, but wasn't sure what. Low branches all around held heavy fruit that smelled delicious. The scent reminded her of something but she couldn't quite follow it.

"If you take her gifts, like, your chakra will be stained her color forever, man. But then you will hear the music too…" Tree looked suddenly depressed and Vinyl noticed her again, able to tear her eyes away from the delicious-looking fruit.

"What do you mean? What music?" There was still the slight clip of sound in Vinyl's ears, wafting to her from her headphones. She wasn't even sure when it got there, but there was a ripe, red-yellow fruit on her hoof, raised to her lips. She took a bite and the flavor of it was pure bliss. In the DJ's mind, music flared, a new beat she was imagining to describe the taste. It would bounce and trip along, as her hoof rose up to her mouth again, then the drop came as the flavor hit.

"If you want to be with your mare, sister, you need to eat it all." Tree trembled, the song in her head was impossible for her to fight, it made her bring the doomed unicorn here.

Vinyl saw the seed in the middle of the fruit, she wondered what this would do to the song she imagined. She bit off flesh around it and gulped the lot down, easily finished in the last of the fruit. The song was strong in her head when she burped. She felt odd, a strange sensation starting to spread out.

The tendrils and roots flowed out from her belly, they searched for safe paths to take through her, catching organs and arteries, winding around them in some cases and slowly exploring the new form. Vinyl tilted sideways and fell, her head pressing against the trunk of the huge tree. The tendrils found her sex and her body trembled in pleasure, it found her head and her pupils dilated under her glasses, the music came.

Vinyl felt the song, the tree's song. Somepony had woven it with the tree and it was beautiful. But it could be better. Her mind found places to add a kick here, a crash there, then she paused and smiled at the tree. She could feel her mane, tiny green tendrils through it, flowering with blue petals that matched her original color. There was a scent around her, a swelling of something that Vinyl barely understood. But she felt something not nice encroach.

Tree reached to the newly infested pony, the song in her head surging and wanting to find a new home. She reached out with it and tried to push it in but there was a song already there, a song with familiar elements. Tree Hugger recognized the song she had sung with the tree, but it had a lot more to it now. It had a life of its own.

The beat halted a moment, the tree behind Vinyl froze mid-tune, then the feeling of a rumble of pressure rocked out from the DJ's head. It had dropped.

The addictive, virus-like song in Tree Hugger's head was shattered, this new tune was real, it was born of the forest but it was stronger, the pony before her had strengthened it and the tree took up the beat. The patter of fruit falling all around Tree seemed in time with it and she embraced the song, smiling beatifically up at Vinyl. "You like, wow…" She was at a loss for words.

Vinyl felt the tree singing the song and grinned, showing her teeth. "Let's do it." The song wasn't of binding and protecting, it wasn't of trapping, this was the original song that Tree had sung here, it was about friendship between pony and plant and more, it celebrated that friendship with every odd beat that jittered and jumped, it pulled the tree from the fugue it had been in and it let it see what mind was responsible for the perversion.

The color in Mellon Dew's mane suddenly wilted, and her eyes went wide, the mare gave a whimper and started to scream. She had fallen to the forest floor and saw the green hooves before her. "You did a bad thing, Mellon, look at your chakra!" Tree Hugger was trying not to feel angry, but the music that sang in her reminded her with every beat what should have been happening. "No… no, don't use her as mulch, that would be too gnarly. Wither, wither, take her gift." Tree lifted her hoof up and pressed it gently to the mare's forehead and felt as the plant within her died.

Vinyl didn't see all this. She was reaching through the tree, rocking along to the beat they had both built and begged it to help her find her Tavi. She lifted her glasses, the red-rimmed irises of the mare, too sensitive to light, now a neutral green, scanned around and she spotted her lover.

Octavia had the song thrust into her head by the tree, it was familiar and different all at once. She didn't object to it but it reminded her of. "Vinny?" Her eyes widened when she saw the green-eyed mare, blue flowers in her mane. She rushed and galloped as fast as she could.

The two collided and the song roaring in their heads got a new stanza as Octavia pressed herself against Vinyl. Her mind was freed of the previous, restrictive song and now she began to weave her own music into it and just the slightest sense of that tune sparked Vinyl to work with her, weaving music into the forest.

"Ponies, listen! You are free! But you must, like, choose. If you want to keep the gift, carry her seed, stand with my bodacious friend over here." The mare pointed to the tree and was amazed at herself. It was the loudest Tree Hugger had ever spoken, but she felt like yelling and screaming, of laughing just for the fun of it. "If you come over here, I will ask the tree to release you."

Octavia and Vinyl turned their heads. Their decision was easy. "Duet?" Octavia's accent, hearing her speak, made Vinyl grin widely and nod. They stepped toward the tree, the music they had created thrumming in the minds of every pony that joined them.

For the first time at a concert, Vinyl and Octavia got to match their music skills and perform not just to a riot of dancing ponies, but the forest itself.

"And like, the tree was sad, it didn't like what had happened and dropped all its fruit, it was way bummed out, man." Tree Hugger, along with Vinyl and Octavia were sitting at the dinner table with Twilight and Gel across from them.

"So what you are saying is this tree, that I looked up, you know." Twilight poked the book before her. "It is a nasty thing…"

"It isn't anymore." Vinyl cut in, grinning. She still wore her shades, but didn't really need them.

"Okay, that you made see friendship because of a song?" Twilight snapped her book shut. "And now you have the plant growing inside you… I don't even know… the book says anypony who ingests those seeds dies within hours. It is a horrible thing!"

Gel poked Twilight on the shoulder. "A horrible thing that seems to have learned a valuable lesson." He turned a smile toward the three mares across from them. "So what now? Is it still growing fruit?"

Tree shook her head. "She has gone right off the idea. She says that she will see how we turn out first." The mare grinned slowly, her eyes lighting up. "She thinks we are, like, her children."

Octavia was captivated by her lover's new eye color, it seemed so different to her normal red but, it worked. She kissed Vinyl soundly. "You will excuse us, sorry, but I think we must… retire." She kissed the mare before her again.

Vinyl shrugged. "Gotta go face the music." Her smile tilted to the side and she got up, the song in her head slowing, the beat starting to thrum in a way that had poor Tree Hugger blushing, but watching the pair leave.

"So, wait, it won't make fruit again until it sees how you turned out, that is… a while. How long do those things live again?" Twilight started flicking back through her book, earning a chuckle from Gel.

"I am sure Tree will keep it company and make sure things are working out, won't you, Tree?" Gel looked to the remaining tree-touched pony. She smiled serenely and nodded. "Good, because we are having a nice break for the moment and I would like to keep it that way… oh, I had meant to ask, did you see Rainbow Dash today?" Twilight shook her head, Tree too. "Huh, well I might have to try and fly up to her place and see if she is alright."

Celestia lay on her side, breathing heavily after the rather intense bit of fun. Twisty was there with her, pressed against her belly with her ovipositor still deep within the white mare. Behind her, pressed against her spine, was Luna's belly. The spell the pair had made during that first night of lovemaking was perfect and, right now, Celestia had her sister's 'payback' sunk deep in her rump. "This is much better. I like these pranks more, Lulu."

Luna was holding so tight to her sister. She felt so very alive, so much herself that she felt likely to explode if she let go. "You are tight… like we were. We will fix that." She leaned up to rub her cheek against Celestia's neck.

Twisty leaned forward and brought her snout up, kissing Luna and getting a happy sigh from the alicorn. She lifted a hoof to Celestia's belly. It wasn't swollen and huge, but five eggs gave it a little bump and made her happy. "Are you sure you don't want more? I have more."

Celestia giggled at the changeling's enthusiasm. "I am sure you do. Maybe Lulu would like the rest?" There was a slight surge in Celestia's rear as the mare behind her giggled.

"How many do you have." Luna's hoof lifted and rubbed Twisty's shoulder over her sister's. Each time either of them moved, the other felt it in the tight confines of the Princess of the Sun.

"Enough, present yourself my mare, present yourself and I will fill you right up." Twisty started to pull and withdraw from Celestia, her ovipositor not retracting as she watched Luna do the same and raise her plot up, shifting to a better position to receive what she knew was going to be quite the load.

"Fill her, make her swell with your fillies." Celestia felt comfortably full and empty all at once. But she rolled over to watch.

Luna flagged her tail, looking over her shoulder as the changeling moved so very neatly above her. The size comparison was negligible now, the Queen's body a match for her own in stature. The firm belly pressed down on her croup and Luna felt a tightening inside. She didn't banish the spell giving her the shaft still, that could stay and not interrupt the fun.

Twisty felt Luna's back arch as she started to work her ovipositor inwards, pushing it past her entrance and working the slick length deep. Her mare took it perfectly, moaning and groaning. "Ten? Fifteen? Twenty?"

The question, the very idea of it being asked, half-fogged Luna's mind with lust. "T-t-twenty… or more…" She blushed and pushed back, feeling her plot press in against the changeling's thighs. Inside her, she felt the ovipositor start to push and prod her cervix. She had no control over the involuntary muscle but she willed it to relax.

Twisty gave a little shove and felt herself bottom out. She swelled her length, locking it in place within the dark beauty under her. "Twenty? I think Twenty-five."

The first egg pressed to Luna's swollen and ready lips. They parted for the breaching but had to stretch to accept the shape fully. It pushed down, deep into Luna and she moaned. Her words, her reply to the changeling regarding the count, was lost as she felt her body invaded and claimed by the egg. It was within her womb, and she came. Hard.

"There there there, such a needy sister aren't you? I bet you will be wobbling around with all those eggs, maybe you won't be able to move at all?" Celestia had crawled over and curled around her sister's head, one hoof gently rubbing her naughty lover as the changeling above them pumped egg after orgasm-inducing egg into her. Celestia played with Luna's pierced ear as the dark alicorn came again and again, her mind giving way to the physical urge to reproduce, to breed.

Twisty felt a swelling adoration for the pair. A changeling's life truly couldn't be any better than this. "Sixteen." She whispered down to Luna, starting the seventeenth on its journey.
