To Be One with Generosity

As Opal’s mistress sat there in her afterglow of milk and cum, nipples twitching and rightfully free of any thought process of their own, Opal cautiously approached the bowl. Her curiosity was piqued, but how could she refuse her hunger? With a meow of thanks, the cat leaned down to drink from her bowl - tongue blepping in and out and so that she might sate herself with the mixture of the marshmallow-flavored milk and the proper fatty milk it had transitioned into as Sweetie's mind was milked away so smoothly. That, and the cum that had dripped down into the bowl. Opal certainly seemed to enjoy the sweet mixture, given the pleased smile on her face as she lapped up the contents.

As the cat drank it up, Rarity smiled a bit at how cute she was looking. Unbeknownst to the two of them, this milk was special in more ways than one. At the moment, though, Opal just continued to lap the milk up, purring in contentment at the feeling of her hunger being satisfied. As she did, she started to feel a strangeness near her rear legs. This was similar to that of heat, which was something she hadn't felt in a while. For now, it was just dull enough that she could ignore it, continuing to drink up the milk.

However, what couldn't be ignored was the scent beginning to emanate from her sex. For now, it was not so strong as to draw her attention away from her appetite, but it was certainly enough to draw the attention of the tortoise, who would be more than happy to oblige her body's need. The tortoise slowly made his way behind the cat, quietly inhaling Opal's scent to be acquainted with his mate if she didn't strongly protest. To test the waters, Tank leaned forward just a little more and flicked his tongue against the kitty's little clitty.

Sure enough, this got the cat's attention and she pulled her head up from the milk dish, letting out a startled meow as she turned her head to look at what the tortoise was doing. Her expression was a mix of annoyance at being interrupted and curiosity as to why he did that. However, she did not try to pull away from him, just staring a bit to see if he'd do it again or let her get back to her milk for now.

Giving a teasing look, as though to say "Oh, did you LIKE that?" the tortoise held Opal's gaze for a few moments before letting his tongue lol out his mouth again and lap once at Opal's folds while he looked into her eyes.

She let out another meow, but this one had a bit of a moan to it. At this point, her expression now shifted to one that said, "You'd better keep going." And, at the same time, she felt her heat start to intensify, the smell coming off of her getting stronger.

Urged on by both the pussy's insistence and her pussy's insistence, the tortoise teased her by withholding for several moments - exaggerating his slowness. His tongue slowly crawled up the cat's folds from clit to the pinch of skin between pussy and anus. The latter he laid a kiss on to tease the pet.

She shivered a bit from the pleasure the kiss made her feel before pushing against him, starting to get a bit impatient. She knew he was pretending to be slower than he really was, and wasn't having it. At this point, the smell emanating from her was strong enough that Rarity could smell it as well, even if it wouldn't necessarily affect her as strongly as the two animals

Tank obliged her more obediently, giving Opal and himself both a better taste of what they wanted. The tortoise's tongue slathered the edges of Opal's labia before, with little warning, he drove the wet muscle into her and licked all around her inside - hungrily licking at her bestial fluids.

She let out another loud pleasured meow at the sensation of his tongue against her insides, body twitching a bit as more fluids dripped from her. But the more he licked, the more she felt the need to be filled with a different organ of his, so she let out a mewl, letting him know her desire.

Who was Tank to deny her? He swiftly extracted his tongue from her insides and gave her nub another kiss before promptly mounting her, his animal cock prodding her entrance. and teasing her cruelly.

She meowed in distress at being teased like this, pushing herself against him. She hadn't admitted this to him before, but ever since they met back during Dash's contest to choose her pet, she had developed a bit of a crush on him. But even so, she'd never imagined a day like this would come.

Tank had never admitted it, but he too for a long time had harbored a desire to be with Opal. And now that he had his chance, he leapt at it as best a tortoise can. He thrust into her, binding their love together as he squeaked out a moan of pleasure. The tight confines of the cat were far greater than the tortoise could have possibly hoped for.

Opal let out a pleased meow at the sensation of his cock inside her, rolling herself against him. This felt better than she could have ever imagined, and she hoped this sensation would never stop. And, thanks to the special milk she drank just a few minutes ago, that desire was about to be met.

Tank hilted quickly within his crush, his hard shell kissing her anus as he groaned in sexual desire. He began to hump, soon with wild abandon. He was too absorbed in his gratification that he didn't notice when his testicles began to swell. He didn't know it, but Opal's legs were beginning to lift off the ground and fuse with her changing haunches.

Opal, too absorbed in her pleasure as well, didn't seem to notice this either as she bounced herself against him in time with his humping. Each thrust made her meow louder and louder, some of her juices starting to release around him. As this happened, her legs continued to recede into her body. At the same time, the rest of her was starting to shrink a bit as well.

As the bell around the cat's neck got looser and looser, jingling a little less with each thrust, Tank fucked the cat's legs away until they were merely a sack with the lightest patch of snow-white fur. He continued to hump, yet he couldn't so much feel her tight cunny's insides. Unbeknownst to either animal, the rocking of his hips was now righting the arrangement of the cat's insides. Smoothing her out and creating a proper inside for the new form she was about to take.

Rarity, watching this display, was a weird mix of mildly disturbed and also really curious. With what had happened between her and Sweetie Belle just a few minutes ago, she figured that if this was happening, it was meant to. She had no idea it was because of her milk, not that that mattered anymore.

Opal continued to rock herself against him, desperate to get his cum to fill her. At the same time, she felt her tail start to retreat into the rest of her body, moaning in pleasure at the sensation. As they continued their combined humping, she felt her fur start to fall off a bit, exposing herself to the cool air of the building.

Before the cat's tail vanished completely, the last of its nub ran against her asshole, sealing it shut forever as the tail too merged permanently into her body. As the cat's fur began to fall away slowly, starting at the base of her crotch and sloughing off her body up from there, Tank began to moan regularly - his cock feeling much more sensitive than before. He was fairly certain he knew what was going on, and he allowed himself to enjoy it. He encouraged Opal to change - leaning down and rubbing his cock against the carpeted floor, rubbing off her fur to reveal smooth, white, phallic skin beneath that already was growing veins.

While she still could, Opal let out a few meows of pleasure with each rub, her pussy feeling more and more sensitive by the second. At this point, the only thoughts running through her head were about how good this all was feeling. By now she was aware that she was changing, but she wasn't sure why or how. And, overwhelmed by the pleasure, she didn't particularly care. All she wanted was to cum from her cunt for at least once before whatever was happening finished, so she wriggled against him the best she could with her remaining mobility, feeling said movement slow down the further the transformation went along.

Although perhaps completely by accident, Tank allowed Opal to feel the stimulation she craved, as he began to teabag the floor. Balls rubbing against the carpet, and Opal's shrinking pussy stroked by the fibers with each and every thrust. The tortoise did this so long as his catty cock continued to sing her sounds of pleasure - though those were quickly being met with the sounds of bubbling gurgles as something began to leak from Opal's mouth, leaving as wide a trail on the carpet as did the wet and needy folds of her sex.

To Opal's mild surprise, what was leaking from her mouth wasn't drool, but cum. Cum that had to have been from the tortoise she was currently merging with. She let out one last meow of pleasure while she could, feeling her mouth start to shrink and tighten up, becoming the slit of a cock in the process. At the same time, her pussy continued to leak until it sealed up permanently around Tank, preventing her from moving further. But she was loving what was happening, so she couldn't particularly care.

All that remained now were two adorable cat ears, a pair of eyes, and the fur covering the tip of the penis. The last of Opal's visage, threatening to fade away at any moment as Tank went back to jerking himself off with the carpet. Every rock of his hips felt a little more sensitive. Assured him and the former cat that this was right in every way. He began to draw close to orgasm, knowing that would seal Opal's fate and make her part of him forever. He felt just how much she wanted to do that, so he didn't slow his thrusts. Not in the slightest. He wanted to ruin Rarity's carpet with the first of many mind-shattering orgasms the new sex organ would be feeling from that day forward.

Opal, encouraging this, twitched herself against the carpet as best she could, mind overloaded with bliss. Her ears were next to go, flopping against her head and merging with it, sealing off her hearing forever. If she could, she would have looked Tank in the eyes. Part of her was mildly disappointed that she couldn't give him one last glimpse, but most of her didn't care thanks to the bliss of the situation. As this happened, her memories started to go a bit as well. The first thing that she forgot was that she had a different owner. In her mind, Tank was her only owner ever.

As Opal's transformation continued its march to its inevitable conclusion, Rarity thought back to how Dash had looked when she stopped by earlier that day. Knowing what had happened to Pinkie, she realized that the bliss her soon-to-be former cat was feeling must have been how the former earth pony had felt when her change occurred.

Feeling Opal sink further into cockhood, Tank happily helped the cat by humping away more and more of her memories. She didn't need to remember anything when she was a cock. Just needed to feel. Experience the world pleasure by pleasure. The tortoise bent his knees to lower himself closer to the ground. The carpet now not only grazed his new package of baby batter, but instead his balls whapped against the floor - drawing his cock's orgasm closer. Closer...

The next memory to go was her name, as the former cat moaned internally, the only way she could. Cock's don't have names, after all. She felt her eyes close one last time, sealing shut forever as the world was engulfed in darkness. But this was fine, she knew she'd be okay as she felt herself fill with more of Tank's cum, some more pre drooling from the slit where her mouth used to be. She twitched and quivered with need, feeling so close to release.

As his new, perfect cock pulsed against the carpeted floor, Tank knew it was time. Closing his eyes and gritting his jaw, he fucked the floor with wild abandon, telling his body to do what it deserved to do. Told it to make Opal let go of herself and be what it deserved to be. A cock. Nothing more, and certainly nothing less.

As the cock let go of whatever memories it had left, not even bothering to keep track, it twitched hard as cum started pouring out of it, leaving a massive stain on the carpet, one that was growing bigger the more the orgasm went on. And the cock loved every second of it. Why wouldn't it, when this is what it was meant to do?

The last of the former cat's fur fell away, signifying the loss of all that used to be her, save the white shade left now upon the tortoise's member as he orgasmed onto the floor. Yet he continued to rub himself out, riding out his climax and making sure Opal came away all her worries, all her responsibilities - until she was nothing but his throbbing meat - dripping the last of her old self out and becoming his cock forever. The tortoise slumped to the ground, slathering the cock in its old life almost teasingly.

The cock twitched with remaining pleasure as it flopped about in the remains of what it used to be, happy with the life it now led of being just part of the tortoise.

"Well, that was a sight," Rarity spoke up. "I'm not going to lie, I'm going to miss my darling Opal, but I know she'll have a wonderful time being part of you, Tank. Just like I know that Sweetie loves being part of me," she said, lovingly rubbing her former sister.

Not that Sweetie was so much there anymore as she was milked away into pleasure, effectively breastified, but the nipples twitched against the mare's touch - always, always begging her stimulation. Daily milkings would be a must with her new crotchboobs. Let alone the wardrobe edits she would have to make. Meanwhile, Tank simply sighed, tiredly humping the ground until his new cock was fully flaccid and awaiting its next use.

She was looking forward to milking herself each day. Perhaps she'd make it part of her breakfast. And while it would be a bit lonely without being able to actually talk to her sister or cat anymore, she had a feeling things would be just fine.
