Cream Heart knocked on the door of her coltfriend's condo.

"Good evening," Sunburst greeted her when he opened the door.

"Oh, you shaved the goatee?" she asked.

"Yeah. I wanted to try a new look." He stepped aside to let her walk by. She sniffed at the air.

"It smells like another mare in here," she said, giving him a suspicious look.

"Oh, uh, well my mother was actually visiting earlier," he said, which was technically true. "For Mother's Day"

"It smells like another mare in heat," she said with emphasis.

"Well, it is 'that time of the season' for everypony," Sunburst said. Her eyes narrowed.

"Yeah, well it smells like sex," she said.

"Yeah well... she was here with her coltfriend..." he said, which was also technically true. Cream's expression shifted.

"Oh. Oh my! That must have been awkward for you," she said. "I hope that hasn't put a damper on your mood."

"I'm trying not to think about that right now. I'm focusing on thinking about you," he said, leading her to his bedroom. "I've got a surprise for you tonight," he said. He directed her attention to the hoofcuffs dangling from the frame of the head of the bed.

"I never took you for the BDSM sort." He laid her back onto the bed and put her hooves into the cuffs.

"And this," he said, grabbing a sleeping mask out of his nightstand, fitting it securely over her eyes with the straps. "And one last thing..." He turned and walked over to open the closet door.

Just as before, Button Mash had been waiting inside, watching through the slats of the door with the video camera in his hooves. Now it was his turn. Sunburst wordlessly waved him over and Button passed the video camera to him and slowly moved over along the side of the bed. Button was even more nervous than when he had lost his virginity. His shaking hoof reached out, gently caressed the side of her cheek and ran through her mane. He leaned over and kissed her. First on the cheek, and then just at the corner of her mouth. Sunburst followed along, recording everything.

Cream Heart turned toward Button and kissed him back. Button was only too happy to kiss her for as long as she would let him. Sunburst watched with the camera from close by. Button eventually broke the kiss.

Sunburst leaned in close and whispered, "I love you."

"I love you too, Sunburst," she said. Sunburst was suddenly struck with a brilliant idea.

"Just call me Sun," he said before he backed up a bit to give Button room. She smiled.

"I love you, Sun."

I love you, Son.

Button was nearly in tears. Part of him knew that it wasn't how she meant it, but it sounded just the same in his ears. His mouth opened on reflex.

I love you too, Mom. More than you'll ever know.

He didn't allow himself say it. He swallowed back the words.

Button kissed her again and started planting little pecks down along the edge of her chin, onward to her neck. Down past her collar bone and along her chest. He shifted his position on the bed and moved between her legs. He resumed kissing down across her belly, finally to her teats.

It had been many years since she had last breastfed him and now her teats were little more than a pair of large nipples. Try all he might, no milk would flow. Though Button didn't care. He happily suckled each one in turn as he pressed his nose into the fine fur of her abdomen. Beyond the strong musk of her marehood, there was a nostalgic scent in the fur around her teats, subtle pheromones that just made him feel so absolutely safe and comfortable.

He pulled away from her teats to look just below them. There, in all of its glistening beauty was his mother's marehood. For a long minute, he just hovered there and stared at it. He had seen it so many times in his trashy magazines, but that was nothing, nothing compared to the real thing. To have it before him in real life wasn't just a sight to behold, (though it was), it was an entire experience.

Even as Sunburst recorded everything from over his shoulder, Button tilted his head from side to side, mentally committing every line, every curve, every shade and hue of his mother's flower to memory. For the rest of his life, when he closed his eyes at night, he wanted this image burned into the back of his eyelids. And when he closed his eyes he focused on her scent.

The sense tied closest to memory, it tugged at a distant recollection from his youth. When this time of the year came around and his mother insisted that he spend extra time outside 'enjoying the spring weather'. He didn't know what it had been at the time. But he knew now, and he would never ever forget it for as long as he lived. His face felt flushed with excitement.

He was practically sweating. He was sweltering. But it wasn't him, it was her. Barely a few inches away, he could feel the heat radiating off of her pussy. He realized that he hadn't taken a breath in some time, taking a sharp breath and a ragged pant. His hot breath on her pussy made her needy clitoris wink at him.

"Oh Sun-" Cream whimpered.

Button bit back on his lip. He reached out with his hoof, slowly, nervously, as though she were made of glass and might break at the slightest contact. His every heartbeat was a thunderclap in his ears. At last he closed the distance and barely grazed the side of her vulva. It was soft and warm and just as absolutely wonderful as he could have possibly dreamed. Her clit winked at him again, though his hoof was nowhere near it. He moved his hoof to the side slightly, parting her dark-tan lips to reveal her beautiful pink interior.

Just to see and touch her in this way at all, after all those years of stolen glances under her tail and dirty thoughts, Button was terrified. No longer out of fear of being caught, no. But that he might awaken once again in his bed amid sticky sheets, shame, and shattering disappointment, as he had hundreds of times before. Of all the stars he had wished on in the past, he prayed harder than ever before in that moment.

Please, please don't let this be a dream!

Of all the days that Sunburst had come home from a date with the damp fur on his hoof for Button to smell, it was a treat, and a damn tease that he refused to settle for any longer. He wanted to taste her pussy, his mother's pussy. He wouldn't wait another second to bury his face in it!

He closed the distance and pressed his muzzle into her folds, giving her a long, wide lick with his tongue, capturing as much of her essence in one pass as he could. Her clit winked against his nose as he moved, making her moan louder as he just barely brushed against it. He moved back down, probing his tongue as deep into her as he could.

He made his way back up, licking up and down along each side of her pussy. Even as her clit winked at him, flashing like an urgent beacon, he deliberately avoided the one spot that would send her over the top. He wanted to prolong it as much as he could and build up her climax higher and higher. Metal clattered as she writhed against the restraints on her hooves.

"Sun, please!" she begged. By the power of 'please', Button could not deny his mother any longer. He cupped as much of her pussy as he could with his mouth and thrashed her clit with his tongue at last. "Sun I- ah! I'm cumming!" she cried. Just as Sunburst had warned him, Cream Heart was a squirter. And how! A jet of her marecum erupted into his waiting mouth and he swallowed it eagerly. He might not be able to nurse of her milk, but he greedily drank of her honey, taking all that she would give. Her body bucked and heaved as her muscles clenched and squeezed again and again, spurting nectar from her pussy until she fell limp as her orgasm subsided.

Button buried his face into her pussy, probing deeply into her vagina with his tongue again. He wanted nothing more than to drown himself in his mother's wetness until he had to evolve gills. He licked her clit again but he felt her bring her leg back and plant her hoof on his shoulder, pushing him away.

"S-sensitive! I need a break," Cream panted.

Button reared up and began to re-position himself between her legs. Sunburst put a hoof to Button's chest to stop him. He made a bulge in his cheek accompanied with a 'sucking' motion and pointed at her. Button shook his head. They had planned on having her suck Button's dick, but he felt like he was too close. And her mouth was not where he wanted to finish. He reared up and his erection sprang up under him like a steel beam. He was so hard that it hurt.

Sunburst stopped him, and pointed at his dick. Button just shrugged and pointed at his mom. Stellar Flare was a plenty attractive mare by any measure. But simply no other mare turned on Button Mash like his mother. He was sporting extra inches in both his length and girth. And consequences be damned if she noticed, after everything that had already happened, Button Mash would not be denied claiming his mother's pussy at last.

He grabbed her hips and looked at Sunburst, nodding at his horn.

Lift her, he mouthed to him. Sunburst's magic lifted her lower half and Button propped a throw pillow under her butt.

He held his mother's thigh in one hoof and pulled himself toward her. With his free hoof, he had to forcibly angle his dick downward. He had to roll his hips along with it. It was like trying to bend iron. He brought his tip to bear against her vagina. He could feel her soft warmth against his most tender flesh. He rubbed against her just a bit, gaining a bit of her copious lubrication for himself. Like a poor soul, cast adrift at sea for years, at last returning from whence they came, entreating entrance. Button shifted his hips slightly forward. She was very wet, and very ready. With just a bit more pressure, her tight, yet pliable pussy yielded and allowed him to enter. His blunt tip stretched her and slipped inside.

Button Mash could not keep the tears of joys from silently rolling down his cheeks. He was inside his mother at long last. In all of his wildest dreams, he could never have fathomed that he'd ever actually get to have this, this one thing he so desperately craved more than anything else this mortal world could offer.

He pushed deeper into her. He wanted to be as deep inside her as he could possibly be. He wanted to be completely inside her, to be entirely enveloped in her warmth and safety. While his conscious mind could not recall his time in the womb, a deep, unconscious part of his brain sought to return to that perfect state of bliss in the ultimate, purest form of nostalgia. But he had to settle on hilting his shaft into her. His blunt tip resting lightly against her cervix. The size and shape of his penis filled the contours of his mother's vagina perfectly, as though they were meant for each other like lock and key.

He shifted to look down at himself, where his pelvis met her hips and his heavy, full balls rested against her ass. As he did, Sunburst's camera could see Button's unyielding erection shifted upwards within her, visibly bulging through her abdomen.

"You're so big, Sun!" Cream moaned. "You must really like blindfolds!"

"Yeah," Sunburst said. "You being here, in my bed, with the hoof cuffs and blindfold. This is my fantasy,"

"Then we should do this more often!" she said. If Button's dick throbbed any harder, he would have passed out from a lack of blood. "Come on now Sun, don't keep a lady waiting!"

"As you wish," Sunburst answered.

Button Mash held onto her and began to slowly pull back. It was just the tiniest amount at first before he pushed back in. He was afraid that if he ever left this wonderful paradise, he'd never get another chance to feel this again. He wanted to just stay there, together like that forever. But he did move again, a bit more each time.

His brain wanted to stay there forever. His dick wanted to fuck as hard and as fast as possible. Of the two, one was quickly beginning to monopolize the decision making process. With each passing thrust, she became less his mother, and more a mare in heat that he needed to breed. He wrapped his hooves around her and pulled himself up into her harder. He leaned over her and pressed his face into the crook of her neck, burying his face into her mane.

His hips thrusted on their own, desperate for relief. Her hips thrusted back to meet him. He began to move faster and faster. His shaft throbbed thicker, making it harder to pull back. But he was nearing the point of no return. He felt his balls tighten and he pushed as deep and as hard as he could. His tip flared deep inside her vagina, pressed flush against her deepest barrier.

"F-fuck!" Cream moaned, feeling herself cum again, barely recovered from her previous orgasm. Button could feel her muscles gripping him as he struggled to keep thrusting.

He stifled a grunt as his balls flexed and clenched. His shaft throbbed and pulsed as his potent seed pumped deep inside his mother. The first gush exploded into her and filled what little space was left in her vagina. His broad flare gave no exit and the rest of his sperm was forced to go nowhere else but in through her cervix, flooding her womb with a torrent of his pent up, virile sperm as more and more of it spewed forth.

Even after he finished ejaculating, Button's legs pushed against the mattress to keep himself buried as deep inside her as possible. His instinct driving him to keep his mare plugged, ensure as much of his semen stayed inside her as possible. He held her face with his hooves and kissed her hard. It slowly shifted from passion to intimacy as they each came down from their sexual highs.

He didn't think it would be possible, being inside his mother, but he actually did start to go soft. His flare diminished, letting her cervix relax closed and seal itself shut. He spent so much of his foalhood cursing his penis for acting beyond his control, getting hard when he didn't want it to. And now, just as then, he cursed it for his lack of control. Against his will, his penis began to retreat out of her and hung limp under him. Luckily, he learned from Stellar Flare's leaking cream pie. With Cream Heart's butt propped up on the pillow, barely any of his prodigious cum leaked out.

"Wow," Cream breathed. "What was that all about?" she asked, between panting for breath. "In all the time- we've had sex- it has never been- like that! That was probably- the best rutting- I've ever had- in my whole life!" Button smiled and kissed her again. The flood of concentrated testosterone sloshing around inside of her made short work of putting out the flames of her heat. It was relief without compare. "I love you, Sun!" Cream said.

"I love you, too," Sunburst said.

Button kissed her one last time before he started to climb off the bed.

There was a knock at the front door.

And then the sound of it opening.

"Hello!? I forgot my purse!" Stellar Flare called into the house.

Oh shit! Sunburst and Button locked eyes in panic.

"Who's that?" Cream Heart asked.

"Uh- uh- shit, It's my mom," Sunburst said truthfully. "I guess she forgot her purse. I'll be right back. Stay here."

"Not like I have much of a choice," Cream said, jiggling the cuffs on her hooves.

Sunburst looked at Button and aggressively waved him off to go deal with Stellar. Button ran out of the room while Sunburst stayed behind, standing there in silence with the camera in his hooves.

"Hey," Button greeted Stellar, keeping his voice down and trying not to look panicked.

"Hey, I forgot my purse and I-" Stellar's nose turned up and she sneered. "Oh my gosh!"

"W-What? What!?" Button asked.

"You stink of sex!" she said.

"Well you and I just had sex earlier," Button said.

"I definitely smell another mare!" she said angrily.

"Wh- wha- I can explain! I told you my mom was coming over to visit," he said, still trying to stay quite.

"Well explain that!" she said, pointing at his still-exposed penis, glistening with fresh wetness.

"I- I-" Button tried to think of something but Stellar Flare marched past him to his bedroom. She found her purse where she had left it on his night stand. She looked at where he move to, now standing in front of his roommate's bedroom door. "S-she's sleeping!" he tried. Stellar grabbed him with her magic and shoved him aside. "Fuck! Fuck! FUCK!" Button freaked out. There was no time to warn Sunburst as she barged through the door, towing Button in behind her with her magic.

First she saw the other mare on the bed, hooves cuffed and blindfolded just as she had been, not even an hour earlier. Next she saw the stallion holding the video camera. She blinked and did a double take before she realized it was-

"Sunburst!?" she shrieked.

"Oh fuck!"

"Oh, this is embarrassing," Cream Heart chuckled from under her blindfold as she closed her legs, doing her best to hide her modesty. "This isn't how I wanted us to first meet. But I'm Cream Heart. You must be Sunburst's mother."

Stellar's magic released the cuffs on Cream and she pulled off the blindfold.

Cream Heart rubbed her eyes with her hooves, blinked in the light of the room, and looked over at the other mare. And then she saw the other pony.

"BUTTON!?" She shrieked and grabbed the blanket to cover herself.

"You seem surprised. Do you know this pony?" Stellar asked.

"He's my son!"

"Is he?" Stellar held the ashamed colt in her magic out in front of her. His limp penis still glistened with wetness.

"What is the meaning of all this!?" Cream Heart yelled.

"I- I can explain!" Button said.

"Oh I would love to hear an explanation for this," she said. Stellar looked at Sunburst. He stood there, frozen in panic, as if he might not be seen if he didn't move. "Luckily, you need not give one." Her magic snatched the camera out of his hooves, took the tape out of it, and walked back out to the living room. Cream Heart followed after her.

"Mom!"

"Wait, WAIT!" they begged.

Stellar turned on the TV. The tape in the VCR started to play.

Cream Heart's younger, heavily-pregnant self was getting rutted on the big screen. Her moans filled the room in full surround sound, as she and the other pony on screen audibly played the parts of a mother and son until her water broke. Cream Heart was mortified. "I can't believe you found this!" She put her face into her hooves.

Stellar Flare ejected the tape and put the other one in, rewound a bit, and pushed play.

Cream Heart was moaning on screen again. She looked up at herself on the TV, hoof cuffed and blindfolded from just minute earlier. The camera panned over to the stallion rutting her.

It was Button Mash.

Her son.

Stellar glared at her cheating coltfriend.

In the video, he slammed it home one final time and the camera zoomed in. Watching the scene, seeing her son's shaft pulsing and throbbing as he delivered his sperm deep inside her, Cream Heart could feel a pang in her belly remembering the feeling of that moment. Standing there, watching, she finally began to feel the warm cum, that was surely her son's, dribbling down her inner thighs.

"That was probably- the best rutting- I've ever had- in my whole life!" Cream Heart panted on screen. "I love you, Sun!"

"I love you, too," Sunburst said to her from behind the camera.

Stellar bristled and stopped the tape, rewinding it to an earlier point. She already knew what to expect, but it couldn't really prepare her to actually see it.

Her own son, Sunburst, rutting her with a look of pure determination on his face. The same close-up of him cumming deep inside her. "That was by far the best sex I've ever had!" she heard her own voice say on the screen, practically echoing what Cream had said. She stopped the tape and turned off the TV.

The two mares turned around and glared daggers at the two stallions behind them. Faces absolutely crimson, they looked like little colts with their hooves caught in the cookie jar. This was obviously much worse. But it was hard for their mothers to see them any other way than as their little colts. Even as extremely naughty as they have been.

"Oh yes, I would really love to hear an explanation for this!" Stellar said. If looks could kill, they would be dead where they stood. Indeed, Tartarus hath no fury like a mother's scorn!

"Okay, Mom, I know this looks bad-"

"LOOKS bad?" Stellar snapped. "It sounds bad, smells bad, and FEELS bad!" She put her hoof to her belly. "This offends my EVERY sense! My sense of decency! My sense of trust! This is NOT how I wanted to have grandfoals!"

"Button, we're not mad. But we're very disappointed," Cream said.

"Speak for yourself! I'm livid!" Stellar said. She pointed at Button. "And you, you little cheating shit-"

"Do NOT speak to my son that way!" Cream said. "Sunburst probably put him up to it! He used to be his Vice Headpony! He must have influenced him! My little Button would never have done this otherwise!"

"Says the mother who did incest porn," Stellar sniped.

"FAKE incest porn! And I'm not proud of that! I did what I had to in order to make ends meet. And I quit once my son was born." Cream Heart glared at Sunburst. "You didn't need to tell him about that!"

"I already knew you did porn," Button said meekly, staring at the floor. Cream Heart's expression softened. "The other colts at school told me a long time ago. They teased me about it."

"Oh, Button, I'm so sorry! I tried to protect you from that part of my life."

"I didn't want to believe it. But then I found Dad's old magazines," Button said, still unable to look her in the eyes.

"But I destroyed those!"

"Not all of them. And I got the back issues."

"But- but why!?" she asked. He couldn't keep from crying any longer. The tears ran down his cheeks as he looked up at her at last. All of his worst fears had come to pass and his deepest, darkest secrets had been revealed. All that was left was the final truth he had tried to keep buried for so long, from even himself. But he couldn't deny it any longer. The elephant in the room could no longer be ignored now that it was mid-stampede.

"Because I love you, Mom," he said. "I'm in love with you. Even though I know I shouldn't be. But... I can't help it. The heart wants what it wants."

"Button..."

"Did you mean it?" Button asked. "When you said it was the best you ever had?"

"Button-"

"Look, I know I'm in trouble," he said. "I know I'm probably going to the gelding clinic, or jail or Tartarus, or all three! But I just need to know first."

In a flash, the smile that briefly appeared and she quickly suppressed was all the answer he needed.

"Mom?" Sunburst asked, looking at the floor. "What about you?"

"Oh, no, your ass is not smooth-talking your way out of this shit!" Stellar said.

"I know." He glanced up at her over the rim of his glasses. "But that also doesn't answer my question."

"It doesn't matter if it was," Stellar said.

"That's not a 'no'."

"Sunburst!" she snapped. "The son of an incest porn star? I can understand his infatuation-"

"FAKE incest!" Cream insisted.

"But you, Sunburst!? What's your excuse?" Stellar asked.

"What? You think it was easy growing up with my room right next to yours?" Sunburst asked. "The walls were paper thin, but it wouldn't have mattered if they weren't! You were so loud I could hear you every time you had a stallion over!"

"I- I was trying to find a new stallion to be a father to you."

"You were only trying to get off!" Sunburst said with angry tears in his eyes. "And I had to listen to all of it. And yes, I heard all of it. Enough to know what turns you on, and what your favorite position is."

"I'm a mare of flesh and blood! You think I didn't have needs? Needs that weren't being met?"

"Oh believe me, I knew!" Sunburst spat. "You told me every time! Every disappointing one-night-stand, it was me that you vented to!"

"I- I was trying to be candid about sex so that you wouldn't keep being so shy with other mares!"

"Every time you had another stallion over, I would think, oh, here we go again! Another disappointment that I'll have to hear about! I just wished that you would have stopped dating those other guys and actually have a relationship with somepony who actually cared about you! I would get-"
Sunburst clenched his teeth.
"I would get just so jealous and angry! I just wanted to kick the door in and tell those stallions t- to-"
He balled up his hoof. He was shaking. He looked up at her.
"And tell them to stop fucking my MOM!"
It was Stellar who had to look away now.
"I didn't want another stallion fucking you because I actually care about you!" he said. "And I knew I could do it better!"
She couldn't look at him.
"And I did, didn't I?"

She pursed her lips. She was angry. She was angry about what he had done. She was angry at herself for her mistakes raising him. But now she was angry because he was right.

She nodded. "But that doesn't make any of this okay," she said, looking at him again.

"I know," Sunburst said. "I don't expect you to forgive me. But I just needed you to understand."

"Fine. I do."

"..."

"..."

"..."

"So what now?" Sunburst asked. "Jail?"

"Ha! You're not getting off that easy!" Stellar said. "Neither of you!"

"Tartarus then?" Button asked.

"Worse," Cream Heart said. "Parenthood!"

"What!?"

"This is your foal, Sunburst!" Stellar said. "But you better do right by your marefriend! And as for you, Button, I'm holding you to your word! I was a single mother once already. I'm not doing it again!"

The colts' jaws were on the floor.

"I assume that was your plan, wasn't it?" Stellar asked them. "But she and I would have met each other eventually. Did you really think that we wouldn't figure out what was going on?"

They shrugged.

Button looked at his mother, plaintively. "Mom?"

She turned her nose up at him. "You made this mess. You clean it up. If you promised to marry her, then you better keep that promise! Because I'm not planning on being a single mother again either, Sunburst."

"But Mom, I love you!" Button said.

"And I love you, Mom!" Sunburst said to his mother.

"Well unfortunately, colts can't marry their mothers," Stellar said.

Button's face looked like his heart was ripping in half. It was the best sex that any of them had, and now it was looking like it would have to be a tragic memory.

"But... that doesn't mean we couldn't all live together," Cream added. Button's face lit up. "After you get married!"

"Yeah! Okay!"

"But how are we going to find a realtor that can be discreet about our... living arrangement?" Cream asked.

A smug grin spread across Stellar Flare's face.

A good ways outside of Ponyville, away from prying eyes, a sign in the front yard of a rural home declared the house 'sold' by Stellar Realty.

A limousine pulled up to the rural home. Button Mash, dressed in his tuxedo, got out of the back and opened the door on the other side for his new wife, Stellar Flare, still in her wedding dress. They had just come from their wedding ceremony.

Another limousine pulled up behind them and Sunburst opened the door for his wife, Cream Heart. Each of them still in their wedding attire as well from their separate wedding ceremony. The limos drove away and they each carried their brides over the threshold of their new home.

No easy task with how their brides were now heavily pregnant.

Sunburst closed the door behind them with his magic. Once inside, the stallions looked at each other.

"Trade ya?" they asked each other in stereo

Sunburst's magic levitated the two mares and swapped them.

"Thanks, Dad," they both said before they carried their pregnant mothers to their respective bedrooms to start their honeymoons.
