BBBFF's Other Meaning

It was the day after Mother's day. Twilight Velvet woke first. It was still early. The sun hadn't even risen yet. Her son, Shining Armor, was still wrapped in her hooves beside her. He must have had a bad dream and came to her bed. She pulled away, causing his penis to slip free from her marehood with an audible 'plop'. Velvet looked down in horror at the torrent of his thick semen rushing from her vagina as the memory of last night came rushing back.

She recovered from her crisis-mode panic and moved to action. She quickly scooped up Shining in her magic and swiftly brought him back to his own bed. Next, she gathered up the linen, starting them in the wash to soak before it left any incriminating stains. The whole time, she could still feel the remains of him sloshing about inside her. She dashed into the bathroom to... freshen herself up.

She went downstairs, putting on a pot of coffee. She opened her prescription bottle. It was definitely lighter than it should have been. She counted them out. She should have had twenty five left. She had nineteen. Somehow she'd taken six extra ones in the last two days. The gears in her mind turned. She'd told Shining that they were her vitamins. Like the ones he took with his meals. Breakfast in bed. Lunch at her desk. The warm, heady feeling after her meals. She looked at the caution label on the bottle.

Warning: Exceeding dosage can trigger premature estrus.

He'd given her extra! That's what had caused her to behave so strangely. She took the bottle from off the kitchen counter and hid it on the top shelf of the cupboard where he wouldn't find it again. Next came the hard part.

Shining made his way downstairs after the sun had woken him through his window. His mom was already busy making breakfast. She heard him walk into the kitchen and take a seat at the table. He was intentionally moving very quietly. He must have thought that he was in trouble. 'Okay Velvet,' she mentally coached herself, 'just like we rehearsed.' She turned around with a smile. Smiling was important. It was important to show that she was happy, and he wasn't in trouble, and that everything was going to be okay.

"Good morning Shiny!" She said cheerfully. She started setting the table in front of him, setting out the portions of the meal. "Did you sleep well?" Her good mood helped his nervousness to fade away.

"Um, yeah." He said. "Uh, mom, about yesterday, I-"

"I had a wonderful Mother's Day, Shining. You made me so happy. I'm so lucky to have such a wonderful son like you." She said. "But that... special hug that we did, that's only for stallions and mares who love eachother very much. And we can't ever do that again."

"But dad said I'm the stallion of the house."

"Yes, but- but he'll be home later today. So you're not anymore." She tried to argue.

"But I am for a little while longer. And I do love you. Don't you love me?"

"Of course I love you Shining. Don't say that." She said back at him as she finished working at the counter. He got up from the table. He was hard again. He reared up, putting his hooves on her hips. She felt him at her entrance.

"Please mom? Can we do it one more time before dad gets home? While I'm still the stallion?" Velvet spun around, pulling herself out from under him. This wasn't going at all like she had hoped it would. She placed her hoof firmly on his chest, forcing him to give her space.

"Absolutely not Shining!" She barked. "What happened yesterday was- well, it was wrong!"

"But it felt so good!" He said.

"I know, but..." She started. She couldn't deny that it had felt good. The best she'd ever had in fact. But now that she was free of the effects of the overdose, she was firmly in check of her emotions today. "But mothers and their colts aren't supposed to behave that way with eachother! It's wrong, and I was wrong for letting it happen. You might not have known any better but I did. And I do now. I'm sorry about this whole thing, but I am putting a stop to this before it gets any worse." She said finally. His face fell. Her words had actually caused his erection to wilt. It killed her to have to hurt his feeling like this, but she had to stop him before she had to try to wrangle a horny colt thinking with the wrong head.

"Shining, you have to understand, if anypony found out about what we did, anypony, even your father, I would be taken away by the Canterlot guard and I'd never see you again! You don't want that do you?" She said.

"No!" He cried, frightened, hugging her, fearing to ever let her go.

"Okay..." She patted his head. "It's okay. But that's why we can't do that anymore okay?" He looked up at her.

"Just, can't we just- one more time? I won't tell anypony, I promise!" Shining pleaded.

"Shining, I-" She tried again, but saw that she wasn't getting anywhere with him. In a last-ditch effort, she tried a bargaining gambit. "Shining, if you be good, and not tell anypony about this, and we can have one last 'special hug'. But not until NEXT Mother's day!" She said. He let out a sort of anxious whine. "It's either that or nothing!" She said.

"Okay okay! I can wait." He nodded.

"Good. Now I don't want to hear a single thing about any of this until then, or the whole deal is off! You understand?" He nodded. She was confident that he'd forget about it in a year's time. Her stern glare shifted to a neutral smile. "Come on, let's just forget about this whole thing and have breakfast." She said, as they both sat down to eat at the table.

After breakfast, Shining went off to school and Velvet walked down to the Canterlot train station to meet Night Light. The rest of the afternoon was filled with the usual anecdotes of his visit to his mother's that weekend, and all of her little eccentricities. Shining returned from school. Dinner that night was uneventful. As was the remainder of the week.

Two weeks later, Velvet was late. Not that she was running behind to a dentist appointment. She was capital 'L' late. Her cycle was running behind. She feared the worst. She made a trip to the apothecary on the far side of town, where she was certain that she wouldn't see anypony she knew. She bought a pregnancy test.

She paced back and forth in her bathroom. The tester sat on her counter. She re-read the directions again. Allow two minutes after use for accurate reading. - indicated a negative result. + means congratulations, you are with foal! Be sure to make a followup appointment with your doctor. The clock on the wall said that it had been two minutes. She looked at the strip.

"Oh horse apples..."

That night she wore her sexiest negligee, climbing into bed, straddling her husband.

"Oh, hey, what brought this on?" He said with a smirk.

"Oh, I don't know. I guess I'm just in the mood tonight." She lied.

"I guess those hormone pill have finally started working eh?" He said smugly. Quite in fact, after she'd hidden them, she'd forgotten about them herself. She hadn't taken them since.

"Well, hopefully I won't need them after you remind me what I've been missing." She purred in her most sultry voice.

After all too brief a session, she could feel him begin to tense under her.

"Ngh, oh Velvet, I'm gonna cum!" He warned her. She didn't dismount as she normally would. It felt extra good when he came inside her. For him anyway. She'd barely enough time to even get warmed up. She stayed put another moment. "Oh, thank you baby. That felt great after a long day at work. Sorry I, uh, finished so quickly. I'm just tired is all. But what if you get pregnant now?" He asked. She shrugged.

"Well, we'd talked about having another foal before right?" She said smiling. "I thought tonight might be a nice night to try. And it just felt sooo good." She lied. He kissed her as she crawled off of him. His below-average member slipped from her unsatisfied marehood. A paltry bit of semen as well. He rolled over and was asleep a moment after his head hit the pillow. Velvet sat there with her hooves crossed in frustration.

After a moment, she stepped out of bed and quietly walked downstairs to the kitchen. She opened the cabinet and pulled out her bottle of cider and the pills. She poured each down the sink. She needed neither now in her 'condition'. She caught her reflection in the mirror. She put her hoof to her belly. She didn't look any bigger. Not yet anyway. She went back upstairs.

She paused as she passed by Shining Armor's bedroom. It was very late now and he was fast asleep. She stepped inside to fix his covers that he'd torn apart again. She froze as he rolled over onto his back, exposing his massive night wood to her. She silently put a hoof to her marehood and finished what her husband had failed to. A few moments later, she bite her lip, stifling her moan as her small orgasm rippled through her. It was nothing like the earth-shattering one her son had given to her. But it would have to do for now.

She pulled the covers over him. He snuggled into them, pressing his snout into where her moistened hoof had gripped it. His hips shifted rhythmically a few times as he dreamed. She slipped out of the room without another sound.

Ten months later, Shining Armor sat in the waiting room. He was waiting outside of the delivery room. It was exciting earlier when they'd arrived. His mom had said that the foal was coming. But now it was boring. After a little while though, a nurse walked out into the waiting room. "Shining Armor?" She called.

"That's me." He said waving his hoof.

"You can come in now." She said. He followed her to the recovery room where his mom was laying on the bed. His dad was next to her. She was holding a bundle of blankets in her hooves.

"Shining, come here." His mom said. He walked over to her bedside, opposite his father. "I want you to meet your new sister, Twilight Sparkle." She shifted her hooves, showing her little face to him. She was pretty. "Now you can be her B.B.B.F.F." He looked up at her, confused. "Her Big Brother, Best Friend Forever." She said with a smile.

But he would never know.

He could never know.

That he was also her Big Brother, Biological Father Forever.
