A Strong Drink

Walking along the streets of the Crystal Empire, a determined mare was heading to an address she had long committed to memory; the address of her son. Stellar Flare, her mature orange body swayed a little, along with the short curve of her auburn mane, with her dark blue, fine made dress flowed a little in the cool breeze. She had a very focused look in her light green eyes, she had to meet with her son, Sunburst. Her mind filled with every possible thing she was going to discuss with him, and his marefriend, Rarity. Soon enough, the street in which they lived together came into view, and Stellar's lips curled into a smile. For the last two years, Rarity and Sunburst had been dating, and while Stellar was so happy for the couple, this joy was soon becoming impatience.

Almost since day one, the milf mare had been wondering when the happy couple would be making a lovely, adorable grand foal for her, but they always gave her the same excuse, it was too soon. Wanting to try and be patient and supportive, Stellar waited, and waited, and waited, and waited. And now, she was tired of waiting. Two years was long enough, and both ponies have put no effort into having a foal. The milf mare wasn’t going to allow this, she was getting on in years, or at least felt like she was, and wanted to hold a little foal in her arms again. If her son and his marefriend weren’t going to have a foal anytime soon, Stellar would do what it took to make sure it would happen, even if it meant going to their house unannounced to all but demand it of the two. As soon as she reached the door, she knocked almost feverishly.

Opening the door, her son, Sunburst was a well dressed stallion, being the same color scheme as his mother, though with lighter tones, word a dark blue sage’s robes with twinkling, lighter blue stars on them. Aside from that, his mane and beard were quite messy, and he looked at his mother with his blue glasses wearing, eyes in utter confusion. Sure, Stellar had always been a very assertive mare, as well as quite spontaneous as she was heavily prone to going off and trying newer, daring things. But this was a little excessive, even for her. Before he could even utter the words to greet his mother, his mind raced over what she could possibly want that was worth the insane train cost to even get here.

“Mother?!” Sunburst said, finally saying something. “What are you doing here?”

“What? Can’t a mother visit her son and marefriend?” Stellar commented, only to poke her head a little into the house past her son. “Speaking of, where is Rarity?”

“She’s here.” Sunburst commented, rolling his eyes as he knew there was no stopping her now. “Since you’re so insistent, why don’t you just come in.”

“Thank you, Sunburst.” Stellar smiled, pushing her way a little into the house. “Rarity? Rarity? Where are you dear? I’d like to discuss something with you and Sunburst.”

The white unicorn mare, wearing a rather casual, yet finely made shirt with knee long, professional skirt. Her purple mane was done up beautifully, and she looked at her stallionfriend and his mother with dazzling, deep blue eyes. Stellar had always believed Rarity was a very, very beautiful mare, a fine partner for her son. Especially since her professional attitude and strong work ethic helped when it came to any shortcomings he had. And Stellar was certain that Sunburst provided well for the mare. But playful thoughts aside, she silently looked Rarity over, and just like last time she came to visit, she wasn’t visibly pregnant in the slightest.

“Hello, Stellar.” Rarity politely greeted, speaking in her most civilized and lady-like tone. “What brings you all the way to the Crystal Empire?”

“I came to ask if you’ve both made me a grand foal yet.” Stellar said, ignoring the way Sunburst rolled his eyes and Rarity’s eyes twitched a little at the comment. “It’s been two years, I just want to see a little bundle of joy before I get too old.”

“Mother, we’ve been over this.” Sunburst commented, placing a hand on his mother’s shoulder. “Rarity and I aren’t ready for foals. She’s busy managing numerous fashion shops across Equestria, and my job as the Crystallar takes up way too much time.”

“If it helps, my own mother has been just as insistent that Sunburst and I have a baby.” Rarity explained, trying to talk the mare down. “But he is correct. Our lives are far too busy to raise a foal.”

“But I…” Stellar commented, only to surprisingly calm down. Her eyes darted a little before she relaxed. “Well, since I came all the way out here, would you both like to enjoy a new wine I bought during my last trip to Las Pegasus?” Reaching into her large purse-like bag, she pulled out a decent sized wine bottle. On it was some prench label none of them could read. “Before I go, we should at least enjoy this.”

“If it will help put this discussion to rest, sure.” Sunburst sighed, not much of a drinker, but did have the occasional glass during special events. “But I’ll just have one glass.”

“Of course.” Stellar commented, taking the bottle with her into the kitchen. Taking the moments to be alone, the two ponies stared at each other, as if silently trying to come up with a way to speed things along. But they didn’t have nearly enough time, as the milf mare returned. A wine glass in each hand, as a third was floating by her magic. “Here we go.”

The wine had a fruity, very sweet scent to it. Taking the glass, Rarity took a little time to drink it, swirling the glass before taking a delicate sip. Sunburst, who wasn't into any drinking culture, simply downed the beverage, feeling a tingle as it ran down his throat. Stellar couldn’t help but giggle at the sight of her son drinking like that, with Rarity playfully rolling her eyes as she drank her glass. The milf mare drank down hers, taking it in a very refined, sophisticated manner. Once the glasses were finished, there was a small silence about the room, but eventually, Sunburst was ready to tell his mother to leave if there was nothing else, but as he tried to speak, the words got caught in his throat.

“Sunburst?” Rarity asked, seeing how sluggish her partner was getting. But as she was about to say more, she felt an intense heat wash over her. Was she entering her estrus cycle? That couldn’t be right, she wasn’t due for at least another week. “What’s going-”

“I’m sorry, but you both left me no choice.” Stellar commented, finishing her wine as she looked at the two. “Don’t worry, Sunburst is just sleeping, but for you, I gave you something very special.” Rarity tried to say something, but then her eyes widened as she saw something else about the mare, a bulge in her dress. “Oh? This?” She rubbed at her bulge a little as her face was becoming red with excitement. “It’s how we’re going to solve this lack of foal problem.” Her eyes grew even more intense. “Once and for all.”

Atop the bed, the special place for Sunburst and Rarity, Stellar was huffing and panting, her beautiful, naked body was hammering hard and rapidly against her mare fuck victim, who was laying on her back as she was taking the mare’s massive, futa cock into her sopping wet pussy. The older unicorn’s fat tits bounced, rubbed, and pressed against the supple, soft breasts of the younger unicorn. Rarity moaned out from the way this cock was stretching out her pussy, rubbing along all the way into her most sweet and sensitive spots. Things happened so quickly, she didn’t know what was happening until Stellar grabbed her, made out with her, and then threw her on the bed before revealing her monsterous cock.

“You made me do this, remember that!” Stellar grunted, bottoming out her huge length in the mare’s sloppy, soaking pussy. “You made me fuck you, you made me fuck your slutt, tight pussy.” Rarity tried to say something, but only moans escaped her lips. To her side, Sunburst was peacefully sleeping. “Don’t worry. When Sunburst wakes up, he’s going to be so happy his marefriend is finally pregnant. I’m gonna finally have a grand foal, even if I have to do it myself!”

Rarity’s mind was racing, any thoughts that could possibly help her escape this situation was only bombarded by the constantly hammering feeling of the pleasure that rippled throughout her body. She couldn’t form a single word, only moaning out with each thrust that Stellar was fucking into her. The milf mare puffed and panted, kissing back against Rarity’s lips, shoving her tongue in her mouth. The two unicorn horns were letting out sparks as the two were getting close to a hard, hot, thick, and passionate orgasm. Stellar’s cock was throbbing, pulsing and swelling as her huge, heavy balls were tightening against her body. She was getting close to her big release. Rarity’s own pussy was constantly spasming in her orgasms, the drug she had been given had made her so forcibly aroused, even the air kissing at her sweating body was enough to get her to squirt.

“I’m cumming, Rarity.” Stellar moaned, pulling back as she looked down at the mare. Marveling at her gorgeous body, she couldn’t help but lick her lips at the sight of Rarity’s bouncing tits. “You’re going to be such a wonderful mother.” Reaching down, she groped at the mare. “Such beautiful breasts, I can imagine how healthy my grand foal will be when they drink from these juicy things.” Licking her lips, the mare couldn’t help herself. Reaching down, she pulled Rarity’s body a little upwards and suckled on one of her breasts.

She gasped out, moaning as her tongue dangled from the side of her mouth. Stellar’s tongue flicked and teased at her nipple, suckling on it as if she wanted to drink creamy milk from these fat boobs. Rarity came again, her pussy squeezed hard on this cock, feeling as this thick thing was rubbing so deep, even deeper than anywhere that Sunburst had ever been. She felt so dirty, so wrong, so filthy, but she couldn’t help but feel as though she was losing herself to this dick. She hated how much she was cumming, and she wanted to hate Stellar, but anytime she felt anything but pleasure. This mare’s cock was just too good, she was becoming addicted to it. And then another thought crossed her mind.

What would happen after? Was Stellar going to come over and fuck her all the time? Was Sunburst going to find out? Of course he was going to discover she was pregnant afterwards, but what would she say? For a moment, Rarity considered just saying the foal was his, that the two of them had an intense night after Stellar left, and it got her pregnant. But why was she feeling happy about lying to her lover about this? She should tell Sunburst the truth, that his mother drugged then, raped her, and forced her to get pregnant. But then she worried what the milf mare would do to her. Would she just keep her to herself, claim her as a broodmare and have her produce as many foals as she wanted?

Pushing and plunging harder and faster, Stellar’s cock was throbbing and swelling. Rarity knew what this meant. The mare was going to cum soon. She was going to let out every thick and potent drop inside her. The unicorn tried to resist, but every slap of the milf mare’s huge balls against her soft body only robbed Rarity of more and more strength. Stellar’s eyes were rolling back as she was going to cum, and she just couldn’t stop herself as she was fucking all her strength into the mare’s pussy. It wasn’t like she was trying to break the bed, it was more like this fat cocked bitch was trying to fuck Rarity into the floor. Pulling a little back, she grabbed and tugged more at the unicorn’s tits, making her moan out.

“Fuck, I can’t get enough of these things.” Stellar moaned, her face was twisted in a maddening, almost deranged smile of pleasure. “I don’t think I’ll be able to stop after this. I’ll have to fuck you every time I see you. I need to make sure I get you well and get pregnant.”

The throbbing cock inside the mare was stretching and rubbing along the unicorn’s inner folds. The thursting, slamming motion became so intense, it was like the entire room was shaking as the milf mare was ready to cum. Rarity only managed to get one last look at Sunburst. The way he was peacefully sleeping through this entire ordeal, it both hurt and fluttered her heart. She wished he would miraculously awaken, saving her from this vile assault. But equally, maybe it was better he never sees this. She could only imagine the vulgar, unlady-like look on her face. She didn’t want him seeing her cumming as his own mother was raping her pregnant. Stellar chuckled, feeling the way Rarity’s inner canal was folding over and squeezing it. It was enough to push her over the edge.

“Here it comes, Rarity.” Stellar moaned out, moving her hands to better grab at the sides of Rarity’s body as she brought down her hardest thrust. “Get pregnant, you beautiful bitch!” As her cock bottomed out into the mare’s pussy, she brought her mouth over hers.

As the two mares made out, moaning in the other’s mouth, Stella’s cock exploded with orgasm. Having fucked its way against and then partially through her cervix, she released her hot and potent seed into her. Rarity’s eyes rolled back, tearing up as there was no going back now. Her ovaries were in overdrive, practically causing her sweating body to steam faintly. The hot, thick, potent spunk flooded all over her womb, coating her inner lining with this seed. There was no way she wasn’t pregnant now. If anything, the only question would be just how many foals she was going to give birth to in the coming months. Stellar only continued to hold herself in place, not moving her cock another inch, making sure Rarity’s womb didn’t waste a single drop.

“So good…” Stellar cooed, slowly pulling her mouth off Rarity’s. Their two embracing tongues parted, leaving a very faint line of drool between them. The milf mare’s laughing, happy face horrified her. “Isn’t this wonderful, Rarity? You’re pregnant now. My own breeding slut.” Her eye twitched slightly, as another sinister thought crossed her mind. “I’m never letting you go. You’re going to give me grandfoals, all of the grandfoals. I’m going to make sure you’re always pregnant with my beautiful, precious grandfoals!”

Rarity couldn’t say a single thing to stop her. Stellar had gotten what she wanted. She had drugged her own son, drugged his marefriend, raped her, and now was laughing in her madness at how happy she was at getting her pregnant. Rarity looked up at the milf mare, and while she felt fear, there was another feeling, pleasure. She and Sunburst have had sex several times before, even before they started dating, but Stellar's cock was just better. It was bigger, thicker, and managed to rub along and press against each and every sweet and sensitive spot about her. She loved Sunburst, but her body had submitted to this mare and her wicked, meaty cock. As the milf laughed, Rarity couldn’t help but give in, letting out a weaker, more nervous laugh as well, showing just how broken she had become.

“Hmm…huh…” Sunburst stirred, slowly opening his eyes. Immediately, he burst up, nearly falling to the floor. Looking around, he was on his bed, resting comfortably. “What…what happened?” As he leaned up, he noticed just how massive of a mess this bed was.

There were numerous stains, tears, and other implications of the most intense fuck imaginable. Confused, Sunburst couldn’t figure out what had happened. He remembered his mother came, and she brought some rare wine, or something. But everything after that was a blur. Was she still over? What time was it? Rubbing his head, he tried over and over to recall what happened, but nothing came to mind. Lifting the blanket, he saw he was naked, and his own cock was limping, and coated in drying cum and mare juices. This couldn’t be right, he couldn’t have fucked Rarity after his mother left, could he? While he was pondering and pondering, the bedroom door opened. Walking in, his marefriend, dressed in the special nightgown he had gotten her for Hearth’s Warming, something she only wore when she was in the mood.

“Good morning, stud.” Rarity playfully giggled, winking at the stallion. In her hands, was a large platter of breakfast food. “I figured, after last night, you’d be very hungry.”

“Last night? Y-yeah…of course…” Sunburst commented, not wanting to admit he didn’t remember anything. But from the looks of it, he and Rarity must’ve fucked all night. “T-thank you.”

“Anything for you, darling.” Rarity cooed, placing the platter on the bed and sitting softly besides her lover. “You were so wonderful last night. Like a wild beast claiming his mate.”

“R-really?” Sunburst nervously asked, still playing along. “I…I’m glad you liked it.”

“LIke it? I loved it.” Rarity cooed, kissing at Sunburst’s cheek. “As soon as your mother left, I don’t know what took over you, but you carried me to the bedroom, and ravaged me all throughout the night.”

“I did…I-I-I mean…y-yes…I did…” Sunburst stuttered, deciding it was better to trust Rarity than to question. And instead, he began eating the breakfast food. “Oh wow! Rarity, this tastes amazing!”

“Aw, thanks.” Rarity cooed, kissing at Sunburst’s cheek. “I’ve already had something to eat. So please, enjoy it all.” Sunburst did just that, and she got off the bed to leave the room. “When you’re done, how about you join me in the shower?” The stallion eagerly nodded at his lover, making her giggle lovingly.

She hated to lie to him, she hated how she used him in his sleep to cover up what Stellar had done to him. But she had no choice. She was pregnant, and at the very least, Sunburst would believe the foal would be his. She loved him too much to hurt him with the truth, but then her thoughts went back to her soon to be mother-in-law. There was no way the two of them wouldn’t be married after Sunburst would learn of Rarity’s pregnancy, and Stellar would be absolutely ecstatic to spend more time with her. Her body trembled, she felt so weak, and yet so hot and aroused by it. The milf mare’s massive cock, utterly destroying what should belong to her son, sent a shiver of excitement down Rarity’s spine as she was getting ready to turn on the shower.

“I can’t let Sunburst know.” Rarity weakly cooed, getting naked and hoping in the shower. Rubbing along the area just above her womb, she could still feel the way Stellar’s cock had claimed her as her breeding slut, and she only imagined just how many times she was going to be raped by the milf mare, or would she just submit and take the intense breeding? Whimpering, she cooed again. “I’ll never let him know.”
