To Be One with Generosity

"Well, I think today went VERY well," the unicorn said to the tortoise as she sat on her couch.

Following her despite his sexual exhaustion, Tank climbed up onto the couch with the mare, smiling and giving "Sweetie" a kiss on either wet tit.

Rarity let out a light moan herself at this as she gently rubbed his head. "Thank you, Tank. That's wonderful of you."

The tortoise looked up, flexing his brows at Rarity in a suggestive manner, as though offering his sexual service to his temporary pet sitter.

Rarity smiled at him as she adjusted herself, turning her body so that she now laid on the couch, giving him easy access to her crotch tits.

The tortoise moved to oblige Rarity's mirrored desire, poising the tip of his quickly recovering cock at the entrance of the white valley of Boob. He had Rarity mounted like that, and he gave another kiss to either of the precious, perky mounds.

Rarity felt her tits twitch a bit in pleasure at the kisses. "Go on, Tank, use my dear Opal to please Sweetie," she encouraged. They both knew that using the names at this point was unnecessary, but it felt comforting for her to still use them.

Tank grinned, giving the mare a knowing smirk as he slowly slid his erect cock between the impressive assets. White against white, soon to be covered in even more white. Very soon, as Tank was already opening his jaws wide and accepting one of the nipples into his mouth - soon sucking on the mare's new breasts.

Already, a bit more milk was starting to come out of the nipple, causing Rarity to moan loudly. "Oh my.... that... that feels divine... keep it up darling," she said. Normally she wouldn't dream of having an animal down there, especially not a tortoise. But with the kind of day she'd been having, pretty much all of her limits had been pushed aside, and now she was open for anything.

Tank could only happily do as Rarity asked, opening his mouth wider and letting the nipple into the start of his throat as he sucked down more of the fatty milk. No more marshmallow, no more worries. Just a needy tit leaking its milk. The white cock was withdrawn and then placed back, Tank slowly thrusting in and out of Rarity's crotchboobs.

"Mmmm..." Rarity pumped herself back and forth in time with Tank's thrusts, feeling more milk leak out each time, making the already white cock even whiter. They'd barely begun, and she was already feeling amazing. She'd have to convince Rainbow Dash to let her petsit Tank more often. But that was a concern for later.

Tank switched nipples when he'd gotten bored of the first, picking up the speed of his humps as he sucked down more of the fatty nectar of life. A small part of him envied the jiggly tits and the hot cock concealed from his view - but being "on top" like this was much more satisfying for the wise animal. His shell whapped needily against Rarity's boobs, the milk jugs quaking with each slap-concluded thrust.

The harder Tank suckled, the more milk seemed to come out of the tits. It seemed like they'd never stop producing at this point, but Rarity wouldn't complain about it even if she had the mental capacity to. Right now, however, she was just giving herself to the pleasure of what the tortoise was doing, feeling some cum starting to slip from her pussy as a result of the pleasure his ministrations were giving her.

Tank swallowed dollop after dollop of the rich, creamy milk - moaning gently into the pliable flesh of the breast. He was doing that regularly now, the warm milk and hot flesh working together to pleasure him more than even his former crush's folds had. Of course, the sensitivity she had given him was a great factor in that. No matter - one way or another, he was fucking his sitter's tits with primal desire. He felt the compulsion to blow his seed on the mare and make the wonderful boobs all sticky and hot with his animal cum. As though a distant to thank you to both Sweetie and Opal for their grand contribution to the sex life of both pony and tortoise alike.

Feeling Tank's cock start to twitch, Rarity wriggled herself even harder than she had already been moving, desperate to get him to cum. "Do... do it Tank! Cover me in your juices! Make us both feel divine!" she begged, feeling on the verge of another orgasm herself, but she was holding back as best she could, wanting them both to feel their maximum pleasure at the same time. If she had known what this was like, she'd have insisted on making it so she could try it beforehand. She still had no idea what caused all of this, but she had a feeling she'd get a few answers soon. Either way, it didn't matter. What mattered was getting that sweet, sweet cum on her milky white breasts.

With a final victorious thrust, Tank sucked hard on Rarity's tit, swallowing a great gulp of the fatty milk and pushing Rarity off the edge with him. His quivering cock gave out, and he blew his load in between Rarity's breasts - its stream blocked by their fat. His seed messied the mare's crotchboobs' valley wonderfully. A river of cum and milk, fur stained and sticky and gloriously decorated by the cumshot and milking alike.

At the same time as he came between her breasts, Rarity blew her own load, her juices mixing with his cum and her milk. She had never felt this kind of pleasure in her life, and she was looking forward to feeling it again later. She'd have to shower again later, but for now, she just gave herself into the pleasure of being covered in his cum and her milk. "This... this is so.. amazing..." she moaned out as she came.

As the former cat was soaked in her former mistress's milk and the new salty substance of her permanent form, the cock mindlessly twitched between the breasts, enjoying its bath as its owner opened his mouth and let the nipple go free - thoroughly swollen from all the attention. He slumped against Rarity, kissing her stomach sweetly after their romp.

Rarity tiredly wrapped her hooves around him in a hug, letting him know just how much she appreciated what he had done for her. She closed her eyes to try to get some sleep for now, but this was interrupted by the sound of a familiar scratchy voice.

"Well... I missed a lot," came the voice from a certain prismatic pegasus.
