It was late in the evening when Night Light arrived home from work.

"Velvet!" he called into the house. "I'm home."

"I'm upstairs," she called back. Night Light put his bag down and poked his head back outside. The flag on the mailbox was up. He trotted back outside and grabbed the mail, sorting it on the kitchen table. Bills and junk mail mostly.

"You got something from your publisher, honey!" he said.

"What is it?" she asked.

"Some kind of package," he answered. She trotted downstairs to the kitchen. "Here." He passed the package to her. She pulled the strip open, letting the papers slide out. She read over the cover letter, read it again and flipped through the other pages. Her eyes widened. "What is it?" he asked.

"Random Horse Publishers wants to send me on an trip all across Equestria and write about it for their Equus Geographic Annual!" she gasped. "There are itineraries in here for the next eleven months!" she said.

"We're going to see all of Equestria!?" Night Light asked, excited. Velvet poured over the contents of the package.

"There's just the one ticket," she said. Night Light's smile faltered.

"That's- that's still really great news," he said, trying to mask his disappointment. "When is it?" She looked at the date on the ticket.

"I leave Canterlot in two weeks," she said.

"That doesn't give you much time to prepare," he said. "Or me." The sudden realization of leaving hit her.

"Do you... not want me to go?" she asked. He put his hoof on her shoulder.

"Velvet, this is a once-in-a-lifetime opportunity! Of course you should go," he said. "But I'd be lying if I said that I wouldn't miss you." He kissed her.

"I'd miss you too," she said. "Eleven months is a long time though." He kissed her again.

"And I'm sure you'll tell me all about it when I see you afterwards," he said, holding her tighter. She smiled, nuzzling into his shoulder. A skilled, passionate lover he may never have been. But a better husband, she never knew.

"And you're sure you have everything?" Night Light asked again on the station platform, looking over her bags in the evening sunlight.

"Yes!" Velvet reassured him. "We triple-checked the checklist to make sure we didn't miss anything when we double-checked the checklist." She glanced over her shoulder as the porter grabbed the last of her checked luggage, bringing it into the freight car. All that was left was her carry-on in her hoof. "And even if we did, it's too late now." She smiled. "Besides, the publishers said that they would provide anything I needed for the trip that I didn't bring. I'll be fine!" she reassured him.

"ALL ABOARD!" the conductor called out the final boarding call to the platform. Night Light hugged her again, one last time.

"Be safe. I love you," he whispered.

"I love you too. I'll write you whenever I can!" she said, squeezing him back. "I've gotta go." She boarded the train, waving goodbye to her husband from the window as it pulled away from the station. When he could no longer see her train in the dusk's fading light, he turned and left the platform. It had been a long walk from home to the station. The walk back was longer.

He made a detour to his favorite tavern. One he hadn't frequented in some time. Velvet never particularly approved of it. But then, she wasn't here now, was she? He sat down at the familiar bar. But he didn't recognize the bar tender. Or any of the other patrons. They all looked so young. He felt very old in that moment. He ordered a drink. And then a second. And more until he was just shy of forgetting why he was there.

"Another, Pops?" the barkeep asked him, nodding at his empty mug. Night Light wavered in his seat. Friday night or not, he still needed to be able to get home.

"Nah, I'm good," he said, pushing some money across the polished wooden surface to settle his bill.

Night fumbled with the lock of his door for a moment before pushing it open. The house was dark. But even drunk, he could navigate his home blindfolded. He walked upstairs to their bedroom and fell onto his side of the bed. He rolled over and his hoof flopped onto the empty space beside him, where Velvet would usually lay.

For all the times he cursed her for snoring, or stealing all the covers, he found himself missing her. He felt a wetness on his pillow. The bed was too big for just one pony.

Princess Twilight Sparkle walked up the steps to her foalhood home. She'd been so busy in Ponyville over the past couple of years that she had barely visited her parents. Even less so, now that she was a princess with so many new responsibilities. In all the chaos of battling with Starlight Glimmer in a time loop, she'd already forgotten to visit for her mother's birthday. She would not make the same mistake for Father's Day. She knocked at the door and waited a while. She could hear rustling inside, things being knocked over. After a few moments, her father finally opened the door.

"Hi, Dad!" she said and she leaped forward to hug him. He was surprised at first but hugged her back. After a moment of embrace she let go. He took a step back inviting her inside. It was then that she got her first really good look at him. His fur was scruff, and his mane was disheveled. He looked tired, unkempt. "Dad, uh... are you okay?"

"Yeah, uh, yeah I'm fine." He scratched the back of his neck and tried to surreptitiously straighten his mane out. It didn't go without notice. "I just wasn't expecting anypony today."

"Really!?" she asked.

"Yeah. Why?" he asked. Her father was many things, but a good liar he was not. Twilight could tell that he honestly had no idea why she was there.

"Dad, it's Father's Day!" she said. He looked at her strangely and ducked back inside looking at the calendar.

"Is it really June already?"

"Yeah, it's been June for like, two weeks." She said. He looked even more confused. "Dad, are you sure you're okay? Where's Mom?"

"Probably having an affair." He mumbled a bit too loudly.

"What!?" Twilight shouted.

"No! I- I don't know exactly," he stammered. "She's been traveling for her publisher. All over Equestria. And it's just-"

"Just what?"

"It's just nothing. I'm probably just over-reacting," he said.

"But?" Twilight asked, leading him. He looked at her. She wasn't a little filly anymore. It was times like these, that he was talking about, when he would tell her that she was too smart for her own good. But he could tell that she could see right through him.

"But... for the last few years, there have been a lot of 'long weekends' and trips to other cities and 'work assignments' that she seemed to look forward to way too much. Especial since the Crystal Empire returned. She had been going there fairly regularly. And she would always come back with that sort of... afterglow. You know?"

"You think Mom is cheating on you!?" Twilight gasped.

"She must be," he said. "If she was visiting Shining and Cadance, she would have brought me along too. And I never hear about any of the stuff she's 'writing about' when she goes on these trips."

"But how can you be so certain?" she asked. Night Light sat at the kitchen table and cleared a space in the mess for a drink, grabbing himself a glass and a bottle of Applejack Daniels.

"Last year, I was taking out the trash, and the bag ripped on the railing. I was cleaning up the mess and putting it in the bin, and I found a pregnancy test box." He poured himself a glass. "I had a vasectomy after you were born, so there would have been no reason for her to have needed that."

"No, But Mom... I- I can't believe Mom would do that to you!"

"Now Twilight, stop!" he said, putting his hoof up. "It's not her fault."

"How is it not her fault?"

"She's- she's just a mare of flesh and blood. A mare with needs. And I-" He frowned and sank into his seat.

"What? What's wrong?"

"And I can't meet them. Physically," he admitted. His expression was a mixture of embarrassment and shame. Twilight tried to stay level.

"Dad, listen, I know you're getting older. But there are potions you can use to help your... royal guard salute," she said with the best euphemism she could think of.

"No, it's not that," he said. "It works, it's just... small."

"Small?"

"Yeah. Small. Like, really below average," he said.

"Dad, a micro-penis is a real disability, and it's not your fault. In fact-"

"No, no, it's not that bad," he scoffed, defensively. "It's just- enough to be embarrassing." He went to pick up his glass. Twilight put her hoof on top of it, slamming it back down on the table.

"Show me," she said. Night Light leaned back in shock at the request, his eyes going wide.

"Um. No?" he said, in a mixture of shock and confusion, unsure if she really just asked that of him.

"Why?" she asked, with more innocence than he could have expected of the subject matter.

"Do I even need to give a reason?" he asked, incredulously. Even she could not be that naive. "Because I'm your father! Because it would be wrong and weird!" he said. Twilight rolled her eyes.

"Dad, you used to change my diapers. You've seen my genitals plenty of times. Was that weird?" she asked.

"That was entirely different. We're both adults now," he said.

"Yeah? Well one of us is acting very childish," she said. She stood up and turned around, lifting her tail, flagging it at him and showing off her marehood.

"Twilight!" Night Light reflexively tried to look away, but found that he could not. Daughter or not, it was the only pussy he'd seen since Velvet had left almost a year ago. It glistened with her juices and her tail wafted her aroma at him. All too quickly she sat back down. "There. You've seen my adult genitals. Now they're old news. So why don't you just- oh, okay, here we go." Night Light didn't realize it at first, but seeing her like that was having more of an effect on him than he knew. His shaft began to emerge from his sheath. He tried to cross his legs and turn away, afraid to admit that she had turned him on so.

"Twilight?! What are you- are you?-" He tripped over the words. Twilight could see his nostrils flaring reflexively as his breath grew ragged.

"What?" She looked down at her own flank. "Oh, yes. Well it is June. I must be getting into season." She turned her attention back to him. "But enough about me..." She grabbed his chair and turned it back to her. He had become fully extended, hanging low. "Does it get any bigger?" she asked.

"You know, every time I hear that question, it doesn't get any easier," he replied. Twilight thought about what she'd asked and realized how insensitive it sounded.

"No! No! I didn't mean anything by it!" she apologized. "I'm just honestly asking." Night Light looked down at her as she leaned in closer. He could tell that she was dead set on this, and there could be no dissuading her.

"Uh, no, it gets a little bit bigger when it gets harder," he said as matter-of-factly as he could, trying to keep the mood as clinical as he could manage. He stilled tried to squirm away. "Come on Twi, I know you've studied pony anatomy. You know this."

"Yeah, but I've never seen it," she said.

"Yeah, well the show's over now so- wait what?" he asked.

"I've never seen one, well, outside of a diagram in a book," she explained. "Can you make it harder? Do you need to see my vagina again?"

"I uh-" Before he could even comprehend what she'd just said, Twilight was on her hooves again, with her tail lifted and her butt pointed at his face, closer this time.

"The aroma of a mare in heat should help you become aroused. Is it close enough for you to smell?" she asked.

If he leaned forward mere inches, it would have been close enough for him to taste!

Twilight could see the effect immediately as his penis stiffened and pointed skyward, throbbing hard with each of Night Light's rapid heartbeats. "Ah, there we go," she said. She trotted over to the kitchen drawer, full of all sorts of random junk. She found what she was looking for quickly, a seamstress measuring tape. "Okay, now hold still." Before Night Light could even object, he felt her take grasp of his penis in her hooves. His body went rigid at the contact. She held him firm and laid the measuring tape in place, measuring the length and the circumference. She made a mental note of the values.

"Well, it looks pretty big to me," she said at last, still holding onto it, moving it from side to side, inspecting it from every angle. "These too," she said, cupping his balls in her hooves, lifting them gently to get a feel for their weight. "They feel so heavy. They must be very full." She moved her hoof back up to his shaft, stroking it gently. "Any mare would be lucky to be able to have this inside her," Twilight said, playing with it a bit more, admiring its size.

"Uh... thank you, sweetie," he said still feeling very awkward. "I wish your mother thought that." Night Light said through his teeth, trying to keep his composure as his daughter jacked him off.

"Well Mom doesn't know what she's missing, then," she said. Twilight fidgeted in her seat on the carpet. It both eased, and yet worsened, her own burning need.

"Twi, you ugh- you ahh, need to stop thaaahht!" he said. Twilight looked at her hoof and realized what she must have been doing to him.

"Oh my gosh, I didn't even realize!" she said. "Are you going to ejaculate?" She sounded more excited than she ought to have. In her excitement, her hoof moved faster. "Will it be a lot?"

"YES! I mean no! I mean- please let goooooOOOOOHHH MY GOSH!" he cried out as he felt himself go past the point of no return. Night Light's first spurt shot straight up, landing on his daughter's horn. Twilight instinctively looked up as the second glob landed on her nose, and the third on her upper lip. The rest of his cum dribbled down onto her hoof. She let go of him and it slapped against his belly, spent of its load.

Night Light didn't feel the normal, euphoric rush of orgasm. It had come on so quickly, and ended just as fast. He hadn't cum like that since he first discovered masturbation as a pubescent colt. He had quite literally gone off half-cocked. While he hadn't gained the pleasure of the orgasm, he did at least lose the general discomfort of his dry spell. At his legs, Twilight reflexively licked her lips, tasting her father's semen.

"Hmm, interesting taste," she commented with the studious tone of a food critic. "But I wasn't ready so soon. Let me get my graduated cylinder from my bag so I can measure it. Can you ejaculate for me again?" Night Light's head was spinning. It had been a long time since anypony had touched him like that. But this was his daughter! As she rummaged through her bag, she unconsciously flagged her tail at him again, winking her clitoris. He didn't even have a chance to process why she would even have a graduated cylinder. He tried to shake himself out of her hypnotic trance.

"Twilight, no! We can't be doing this! I've already let this go too far," he said sternly, trying to keep some kind of position of authority. "You're my daughter!" She just rolled her eyes.

"Would you relax? "Here, think about something else." She backed up toward him, as he tried to lean back and away, unwilling to use kinetic magic against her. He was trapped in his chair. "You can pretend that I'm Mom, if that helps."

"Twilight, that is- That is not at all the issue!"

"Shhh." She shushed his protests as she backed up and touched his snout with her nethers, wetting it with her juices. He tried to squirm away, inadvertently pleasuring her with his movement on her. She held him in place and gave him a good rub on his nose, getting him thoroughly coated.

She sat back down on the floor, unconsciously rubbing herself against the rug. She finished getting her measuring instruments ready. His tongue reflexively licked his face where her wetness was on him. 'She tasted even better than she smelled,' he thought. Even as he berated himself for enjoying such a thing, she could see him getting hard again already as he licked his nose.

"Twilight I-"

"Now, now. I tasted you, so it's only fair," she said, "you can thank me after."

"After what?" he asked. Her only reply was kneeling in front of him and taking grasp of his stiff dick again, stroking it as she pointed the tip at the opening of a graduated cylinder. "Twilight!" he shouted.

"Relax, I said! It's for science!" she said. He felt torn. Even as certain as he was of Velvet's infidelity, he still loved her. He didn't want to betray her. Least of all with their own daughter! But his daughter's hooves on him felt incredible. Her scent filled his nostrils and her taste lingered on his tongue. His mind became fogged, overcome with her arousal, and his own. It had been too long since he'd felt the touch of a mare. And here one was touching him in earnest. And it felt good. It felt so damn good.

"Well... if it's for science..." he finally relented. "... could you... go a little faster?" Twilight grinned.

"Of course, Daddy," she answered.

"Daddy?" he asked as his legs trembled. "You haven't called me that in years." Twilight set the cylinder on the floor. She used both hooves to stroke him faster. She flicked her head aside to get her bangs out of her face. She looked up at him from between his legs with those deep, purple eyes.

"Yeah, well..." she trailed off as she stroked him. Her eyes alternated between looking up at his, and focusing on her work with his cock in her hooves. Her horn and mane were still sticky with globs of his fresh cum. With each passing moment, as he looked down at her between his legs, she became easier to see as a mare, and not his daughter. The last shred of his mental conflict melted away as she gently cupped his balls again.

"Poor Daddy," she cooed, feeling the weight of his balls. "They're still so heavy. You haven't had anypony to help you empty them."

"Twi-" he moaned. His cock began to flare.

"Wait! Don't ejaculate yet!" she scolded, taking her hooves off of him. "Wow, ready again so quickly?"

"Sweetie, it's been a long time for me," he groaned, feeling uncomfortably denied after being so close to cumming again.

"Well if you can hold off your orgasm, your testicles will produce more volume," she said, waiting for his flare to subside.

"Twilight. Baby. Are you really going to tease me after all this time I've already waited?" he whimpered like a little filly with a skinned knee. His erection throbbed with each beat of his heart.

"Does it hurt?" she asked, both out of concern and academic curiosity.

"Yes. I mean, a little. It's uncomfortable for a stallion to be this close to finishing," he explained. "You don't want to give your dad blue balls now do you?" he asked.

"Your testicles ache?" she asked. He nodded. "Oh, I'm sorry." She extended her hoof and gently held his balls again, rubbing them slowly. "Here," she said, "I'll kiss the boo-boo and make it all better." She leaned down and kissed each of his balls. He moaned as he felt her lips on his scrotum. "Does that feel better?" she asked.

"A little," he answered. "Could you- um, maybe try licking them?" he asked.

"You want me to lick them?" she asked. He nodded. "Will that make them feel better?"

"Oh, yes."

Twilight leaned her head lower, running her tongue up along each of his hefty balls. They were each nearly the size of a tangerine. With the sort of base curiosity of a mischievous toddler, she wondered if this thing in front of her could fit in her mouth. As though reading her mind he asked her.

"Could you try sucking on them a little?"

"O-okay." She opened her mouth as wide as she could, careful to keep her teeth clear of his tender area. She took one of his balls into her mouth, sucking on it like a popsicle.

"Ow! Not so hard," he said.

"Oo, auhhy," Twilight tried to apologize with her mouth full.

"It's okay. Why don't you just focus on this, instead?" he said pointing at his shaft. She let his ball slip free from her mouth and put her hooves back on his dick, rubbing it again as she had before. "Well, actually, I meant with your mouth," he said.

"Right. I suppose that would be an adequate simulation for intercourse," she said, looking up at him. His dick obstructed most of her view from her perspective. She knelt upright once more, angling his dick with her hooves. She could feel her own wetness dripping as she lifted herself from her seat on the sopping-wet carpet. She looked down at the tip of his dick, aimed at her face. The next step seemed simple enough, yet daunting all the same. She opened her mouth as wide as she could again. It was at least a little thicker than his balls were. Keeping her teeth off would be a chore.

"Oh, Twi," he moaned as she managed to get the head of his dick into her mouth. As big around as it was, she could only manage to take a few inches before her mouth was completely filled. She pressed her tongue against the tip. She could taste the droplets of precum dribbling from him. It tasted a little more watery than his semen proper. But not at all unpleasant. "Oh my gosh! Your mother would never do this for me," he said as his head rolled back. She didn't have much of a range of motion. She was only able to bob her head a little. But it seemed to please him well enough. She used her hooves to work the rest of his shaft at the same time. She felt his hoof running through her mane, rubbing her head softly in encouragement as she worked.

"Twi... Twi... Oh Twi!" he moaned louder. She felt him grab her horn with his hoof, holding her down on his cock with a bit more force. She braced herself with her hooves on his legs, keeping her from going any further. His hips bucked involuntarily. She felt him flare inside her mouth. He was about to cum. Twilight had better leverage and pushed herself off of him, freeing herself from his hoof's grip on her horn. "Twi!" he cried out, denied a second time.

"Just a sec!" Twilight grabbed the graduated cylinder, bringing it to the tip of his penis. She realized just how woefully unequipped she was for such a task. The opening to the tube would be far too narrow for her to be able to aim him with any accuracy. "Hold on just a minute!" she said. She stopped to try to find a funnel.

"Twi! I- I can't!" he cried, writhing in the chair, denied yet again. "I need release!"

"Just wait. I'll be just a minute," she told him. He watched her turn around and bend over, digging for something in her bag. His eyes bore down on her wet marehood, all but dripping beneath her lifted tail. His legs moved on their own. Before he knew what was happening he was on his hooves. "A funnel has got to be in here somewheeEERRRAAAH! Dad!?"

Night Light surrendered to instinct, mounting the presenting mare. It no longer mattered who. Twilight felt his demanding shaft deflect off of her nethers in his first, uncoordinated thrust. In her surprise, Twilight hadn't the time to react. And her magic was preoccupied, levitating the glass cylinder. He pulled back and tried again, finding his mark. He pressed his tip against her wet pussy, forcing her lips to part. "Daddy!" she squeaked in surprise, not fear. She knew that he would never actually hurt her. Even so, her plea for him to stop fell on deaf ears. He grunted and pushed.

Twilight cried out in a pitch usually reserved for bat ponies as she felt her father's penis enter her virgin pussy. She fell forward, down onto her elbow on the carpet. It only served to give her father a better angle as he pushed his cock the rest of the way into her, filling his daughter. She could feel his heavy balls press against her winking clit. Unlike when she pushed herself into his face, she was not in control of the sensation this time. And that made the stimulation all the more intense.

She shuddered as he filled a void, scratched an itch, that she didn't even know she had. The quiet discomfort of the heat of her estrus that had plagued her each year. With one swift stroke, he made clear the solution to her problem. And it wasn't grinding against the rug. He pulled back, seemingly acquiescing to her pleas. She could feel him exiting her, leaving her with an emptiness that she had only just become aware of. She found herself wanting him not to stop, not to leave her now.

"Daddy," she moaned now in a throaty, lustful, tone, pleading for him to continue. He needed no other instruction as he pushed forward again, faster this time, refilling her. His balls struck her clit more forcefully, sending a jolt of electricity up her spine. "Yes!" she cried. His dick was thoroughly coated with her wetness now. Free of any resistance, he pulled back and thrusted again. And again. Faster and harder. "Daddy!" Twilight squealed under him. Her legs were trembling, but her knees were locked to support their weights. She could feel a tension growing in her tummy. Like a knot getting pulled tighter and tighter, threatening to snap.

"Oh, baby!" he moaned. Twilight felt him getting thicker inside her.

"Daddy!" she pleaded, "Wait! Don't!" But he only went faster now. He wrapped his hooves tightly around her, pulling her back to him just as hard as he was humping into her. His tip flared. The girth of it struck against her g-spot and he slammed it home, hitting her clit a final time. The knot in her tummy let go. Her pussy quivered and spasmed around him, spurting her marecum against his scrotum. "Daddy!" she cried out.

"GRR!" He held her fast as she came. His balls tightened, ready at last to let loose. She felt his flare stretching her even wider inside. She felt his cock throbbing and pulsing. "I'm sorry baby!"

"No Daddy! Don't ejaculate inside me!" she cried, even amidst her own first orgasm. But it was already too late. She felt the first rush of his hot load deep inside of her.

"I'm-sorry!-I'm-sorry!-I'm-sorry!" he cried, even as his hips kept making little thrusts, pushing his cum deeper. "AH!" A second, third, and forth rope he pumped into her. But he held her tight, despite his repeated apologies, long after he finished cumming, still making little jerks with his hips.

"Daddy, no! I'm in heat! You're going to get me pregnant!" she cried, sinking to the floor with him still inside her.

"But didn't it feel good?" he asked.

"It doesn't matter that it did!"

"Twilight, don't cry," he cooed, laying behind her, stroking her mane. "Everything's going to be okay."

"How? You ejaculated inside my vagina! I'm in estrus. I'm going to get pregnant!"

He laughed at her overly-clinical terminology.

"How can you be laughing!" she said.

"Twi, did you forget?"

"..."

"I had a vasectomy. I'm sterile. I can't get you pregnant."

"... Oh. Oh!" her eyes lit up. She looked back at him. "Why would you scare me like that, Dad!?"

"Because you're cute when you get all worked up," he said. She gave him an elbow to the ribs. "I bet you feel better now."

"Yes. It's quite a relief."

"I mean physically," he said, running his hoof down along her body to her tummy, pressing against the bulge of his cock still inside her. Twilight stretched a bit on the rug beside him.

"Yes, I- I feel fantastic!" she realized, now that the pang of her heat had been sated.

"Daddy knows what's good for his little filly," he teased.

"Hmm." She felt him going soft inside her, slowly retreating from her loins. "Help me up."

He pulled out with a wet 'plop' and helped her up to stand on her hooves. She quickly grabbed the graduated cylinder and the funnel and squatted over it. With a flex of her pelvic muscles, she felt a white rush pouring from her.

"Oh my goodness!" she gasped as she squeezed the last dribble from herself. "250ml."

"Is that a lot?" he asked.

"It's incredible!" she said. "Even if half of that was my own fluids, its still almost double the average ejaculate volume!"

"Well, what can I say?" He smirked. "You bring out the best in me."

"Yeah," she scoffed, "And you put it in me!" He laughed.

"You want me to put it in you again?" he asked. She turned and pounced on him, pinning him onto the floor on his back with her hooves.

"Fine. But this time I get to be on top!"
