“You little perverted slut,” Spike said, but he was grinning all the same. “I bet you were just waiting for a moment to get me all alone with me.”

“Sexy, charming, and sharp, Fluttershy really does have good taste.” She leaned forward closer so that her lips brushed slightly against his ear. “Now, would you like a taste?”

They kissed again, this time though they proved a lot more intense. Their hands roamed each other’s bodies. Spike’s hands pulled down Posey's dress and her tits exploded out of the dress, as Posey yanked Spike’s tuxedo open.

“Very much so,” Spike said, lifting her up by her thighs and burying his face into her tits. They were soft and fleshy, and he was able to stuff his face deep into her cleavage. Posey Shy squealed out in delight and pushed Spike further into her bust.

“Oh gosh! Yes! Just do that!” She squealed, as Spike made his way down her chest. Wrapping his lips around her erect nubs and licking the nipples within him. Another loud moan escaped her lips. “Keep it up! Please have your wicked way with my huge tits.”

Spike gave a triumphant grunt into her cleavage as his hands started to roam her body. First, they tore off what remained of Posey’s dress, letting it crumple to the floor in two pieces, then they started to grope two handfuls of Posey’s huge butt before making their way up to her tits and seizing a good chunk of her titflesh that wasn’t already in his mouth.

“Oh you greedy dragon stud!” Posey moaned in delight. “Are my tits better than Fluttershy’s? Do you love them more than you love hers?”

“I don’t know.” Spike teased, pulling off her tits and mauling them in his hands. “Hers are pretty good.”

“But she doesn’t know how to use them.” Posey Shy suggested seductively, pulling Spike’s hands around them. Then her eyes drifted down to the tent in Spike's pants. "Perhaps you’d like them around your cock. I can see you’ve got a big one, must get awfully cold. Would you like me to warm it up for you?”

“Tempting,” Spike said before his hands moved from her thighs to her ass and his thumbs began to tease her cunt. "But I think this cunt is a whole lot warmer."

"Ah! By all means Spike. Please fuck my pussy, please fuck your girlfriend’s MILF mother,” she begged, a quiver of desperation in her voice. Spike debated whether to reveal his true relationship with her daughter, but he decided it would be more fun to keep her in the dark.

He let go of her ass, letting her fall to the ground. For a second Posey eyed his dick with wonder and licked her lips, tempted to take it into her mouth. Though Spike slapped his cock against her cheek to encourage her to hurry up, not that she had any issue with his flesh against her cheek.

She got up and made her way to the sinks, with the mirrors reflecting her needy expression. Spike suspected that this was exactly why she had chosen this position, so Spike could see her face as she was fucked. She rotated her ass slowly, inviting Spike to fuck her dripping pussy.

“I have a warm pot waiting for you Spike, don’t waste it,” she purred, a breathy desperation in her voice. Spike walked up to her slowly, like a predator approaching his prey. Sure to keep her on edge as long as possible.

“I can see it in your eyes, you need this dick. You need me inside you.” Spike said, holding his dick in his hands, careful to only insinuate the question rather than ask it outright. He wanted her answer to be sincere. “Tell me the truth.”

“Yes Spike, I-I need it,” she admitted, eyes glazed over as they watched Spike’s dick swing like a pendulum. “I’m such a dirty slut, I’ve been fantasizing about this for so long. It’s so wrong but I need this. Please Spike, please fuck your girlfriend’s MILF slut.”

Spike needed no further invitation, he spread her fleshy asscheeks apart, his hands sinking deep into the jiggling ass. Her pussy was gushing like a waterfall, with Posey Shy giving desperate moans and begs to Spike, still twerking her behind to invite him in.

His cock entered Posey’s cunt, effortlessly sliding into her body, his groin slapping against her ass. Desperate moans of delight escaped her lips which soon gave way to shrieks as Spike pushed his big fat dick deeper and deeper into Posey.

“Oh fuck! Please Spike! Please right there! Please! More! More please!” She begged, her face now a scarlet red as a depraved smile spread across her face. Spike saw no reason to reject such a polite request, as he increased his pace. His cock slapped into her well-lubricated pussy like an animal, and Posey enjoyed every second of it.

“You must be such a slut!” Spike grunted as he fucked her. “You’ve wanted to get in my pants since Fluttershy told you she had a boyfriend. That’s why you were wearing that outfit, that’s why you’ve been fucking me with your eyes all night. You’re such a dirty slut, I bet you’ve been waiting for Fluttershy to get a boyfriend just so you can steal me from her. You’re such a MILF slut, tell me the truth!”

“AAH! It’s true, it’s all true! I’ve waited for this day for so long! I’ve been dreaming all the time of stealing a hot stud like you away from Fluttershy! It’s so evil but so HOT!” She squealed as Spike rammed particularly hard into her. He was being particularly rough with her as if punishing her for her perversity and from the way her tongue rolled out of her mouth, she seemed to enjoy it.

“You feel that? That’s what it feels like to be really fucked. You love it, even as your pussy becomes ruined for any other pony. You can feel that too, can’t you?”

Posey gave an ear-splitting scream that couldn’t possibly have been missed outside the bathroom. And indeed Spike noticed out of the corner of his eye that it hadn't.

"Yes! Yes, I can Spike! Please keep going, please ruin me! My husband was never this good! Please make me yours!” She pleaded as she thrust herself back onto Spike’s dick. She was almost ready to cum, but Spike had other ideas.

"No," Spike said firmly, pulling out of her so suddenly that almost gave the poor MILF whiplash.

“What!? No! Spike I need it!” She begged, trying to unsuccessfully thrust herself back onto Spike’s cock. “Why Spike? I need you so bad.”

“You want me to fuck you, then you’re going to have to agree to my demands,” Spike explained, keeping his hands firmly on her ass, preventing her from thrusting herself onto his dick.

“Anything!” She gasped, chewing on her lips in a vain attempt to hide how desperate she was.

“And you’ll keep your word?” She nodded. “I want you to be my sex slave. You’ll come to me whenever I call you, and let me fuck your brains out. You’ll follow any order both in and out of the bedroom. Support me in every single one of my desires, no matter how lewd or immoral, and perform whatever fantasies I desire.” He slapped her ass, sending a lovely moan escaping her lips. “And you’ll do it all without question and in exchange I’ll fuck you whenever I feel like it. What do you say?”

“A-anything, Spike! Just fuck me!”

“Anything what?”

“Anything, Master!” She screamed and Spike smirked. He rammed his cock back into her, and now felt his own orgasm coming on. So he leaned in close and mauled both of her beachball-sized tits in his hands and gave her first order.

“Cum.”

She obeyed instantly. A shudder rippled throughout her body with another ear-splitting scream as the MILF was thrust into the largest orgasm of her life. Spike too felt his own orgasm coming as he shot a vat of cum into her womb, and since Posey was so desperate to have a grandchild Spike decided to give her a new daughter.

“That was wonderful…Master,” Posey said with a big stupid grin on her face as she started to massage her pussy, feeling the vat of Spike’s cum leaking out of it. “So you want me to be your sex slave? You perverted stud of a dragon, it’s no wonder you were so glad to fuck your girlfriend’s mother. Perhaps I should be glad.”

“Oh Fluttershy isn’t my girlfriend, my real girlfriend is a whole lot more beautiful than her, or you. But perhaps you should ask her yourself,” Spike suggested, glancing at the bathroom doors. Posey followed his gaze and realized to her horror that Fluttershy had been standing at the door, with her fingers stuck deep in her cunt.

"Fluttershy!" Posey gasped, hands scrambling to cover her breasts and pussy. “I was just…it’s not what it looks like… I mean.”

“Fluttershy, why don’t you shut your mother up?” Spike suggested, and Fluttershy had a shy yet perverted smile on her face.

“With pleasure, Master.”

“Wait Fluttershy what are doin-MMMPFF!” Posey Shy was shut up as Fluttershy pressed her lips against her mother’s mouth. The MILF scrambling in shock and surprise.

“Do you enjoy that? Incest with your daughter? Your master is certainly enjoying it," Spike said. Slowly Posey's hands stopped struggling, and then started embracing her daughter as she started to return the kiss. Eventually, though they broke away.

"You're okay with this? I mean I thought Spike was your boyfriend?” Posey Shy asked, failing to keep the relief out of her voice.

“Haven’t you been paying attention, Mom? I lied. Spike isn’t my boyfriend, I’m not worthy of being his boyfriend. He’s my Master and I am his sex slave, just like you,” Fluttershy purred, her delight dripping from her mouth like honey.

“So you’re not upset?” Posey Shy asked, her face twisted between confusion, shock, relief, and most importantly lust.

“Don’t worry Mom, I’m not upset, at all. In fact, I’m very happy to hear that I’m not the only pervert in the family.” Their lips met again, this time Posey was much more enthusiastic, and the kiss was quickly becoming more lewd before being interrupted by Spike.

"Nice show, girls, but why don't you both wrap those massive tits around my cock?” Spike asked, sitting back on one of the toilets as mother and daughter brought their massive racks over to him. They wasted no time in wrapping their tits around his cock. Posey’s larger but softer breasts contrasted against Fluttershy’s relatively smaller (by a shade) but perkier breasts.

"So if Fluttershy isn't your girlfriend Spi-Master?” Posey asked, frowning.

“Rarity, she’s my sex slave too but she’s my favorite. The diamond in my horde, you obey her when you’re not obeying me. Understood?” Spike said firmly, and Posey nodded eagerly.

“So Mom what about Dad? What are you going to do with him?” Fluttershy asked and before she could answer Spike interjected.

“You’re going to tell him the truth, all of it. How you wanted to steal me away from Fluttershy, how I’m a much better fuck than he was, how you became my sex slave, how you made out with Fluttershy, you’ll tell him everything. That’s an order,” Spike told her firmly, watching as her face went white.

“Surely that would-”

“That’s an order,” Spike repeated firmly. “Don’t worry about it. Will your husband be glad?”

Posey seemed to be concerned, but Spike knew there would be no reason to worry. Instead he just leaned back and allowed the two to massage his cock with his breasts, hoping her husband wouldn’t get too impatient waiting.
