Marble almost came right then and there, Swift's words were so explicit and erotic that they actually managed to bring her to the edge of orgasm, however she was tipped over and sent crashing into a tidal wave of pure pleasure that coursed through every nerve in her body and flooded her brain with dopamine when she felt the first crack of the whip on her buttocks. Marble let out a muffled scream as her pussy quivered, fluids squirting onto the bed sheets below which Swift decided not to acknowledge much more beyond a smug smile while he carried on with his relentless assault on her rump. Swift continued to bring the whip smacking down on her cheeks, alternating between hitting one cheek before moving on to the other and hitting both cheeks at the same time with varying degrees of force but never so soft that Marble didn't feel the stinging sensation that came with being spanked. Minutes passed and the consistent thwack of a whip on soft flesh accompanied by pleasured moans and groans was still ongoing along with the occasional grunt they both made whenever Swift was feeling particularly violent and decided to tug on the rope attached to her collar. Marble's butt was now in a much worse state, both cheeks were a shocking shade of red and had several welts and bruises peppered all over them, it was on the final strike where Swift was almost certain that he was close to drawing blood, that he finally stopped.

He leaned forward and removed the ball gag that was thoroughly coated in saliva and no small amount of teeth marks, he gently bit her ear before whispering "How was that?"

Marble giggled softly and somewhat maniacally as she said "It was soooooo fucking good...... I love you so much Swift, thank you for doing this to me......"

Swift starting removing all of the equipment from her body, putting it back in the box and said "You're welcome, do you need a rest before we fuck or would you rather we call it a night?"

Marble looked at Swift with a deadpan look and said "Honey, I'd rather go without sleep for a week than not have sex with you right now".

Swift chuckled and said "Fair enough, how about you take the lead on this one?"

Marble lied down on her side to make room for Swift, holding back a wince of pain as she patted the bed and motioned him to lie down on his back. As Swift lied down, Marble clambered on top of him with her legs either side of his body and facing away from him, giving him a perfect view of her long slender back down to the very butt he had been abusing mere seconds ago, Marble looked back at him with a sultry look as she shuffled about until her pussy was directly above his face. Marble let out a breath of satisfaction as she pressed her pussy lips right down on Swift's mouth and said "Eat that pussy, do a good job and I might suck you off, so get licking!" Marble took hold of Swift's cock and gently pumped it while he began to take long firm licks across Marble's pussy, the fact that was she already so moist meant he got to enjoy her taste almost immediately, the flavor of her pussy wasn't something he was able to describe and no comparisons ever came to mind, the only thing he was sure of was that he liked it and wanted more as he pushed insistently at her entrance until his tongue was granted access, allowing him to delve deeper into her delicious folds.

Marble bit her lip and held back a moan, stroking Swift's strongly erect cock faster, tightening her grip slightly, if he was already performing this well she might have had to make good on her promise to blow him sooner than she thought. It was when his tongue managed to locate her g-spot that she had to give up and silence herself the only way she could and muffled her guttural moans of ecstasy by ramming Swift's cock down her throat in one fell swoop. Swift's eyes shot wide open, he didn't know Marble was so skilled at deep-throating that she could practically engulf his entire member without even thinking about it, not to mention how ravenous she was being. Marble was thrashing her tongue around wildly, bobbing her head up and down at a tremendous pace and sucking so hard it was like she was trying to milk the cum out of his balls before he even had the chance to ejaculate, not to mention her throat seemed to take dick like it was nothing. Marble was reaching her second orgasm embarrassingly quickly, she cradled Swift's balls and as gently as possible gave them a delicate squeeze, attempting to coax his body into emptying the fat cum sacks into her mouth.

Unfortunately, while Marble's technique was having the desired effect, she was far too late. She practically ripped Swift's cock from her mouth and threw her head back, screaming to the heavens "FUCK!!!" Swift had finished her off before she could even get his orgasm to start building, which was made extremely apparent to Swift when the pussy he was devouring suddenly rewarding his efforts with a mouthful of the female fuck fluids that he was so fond of, which he swallowed down without hesitation. Marble was panting and sweating, the orgasm Swift had just given her was particularly strong and she felt a little guilty about not even getting his own orgasm started, she got off of him and said "I'm... sorry babe, that was... phew, that was fantastic...... I think you deserve to cum as well though, anything else you want before we set up a meeting between your cock and my pussy?"

Swift thought for a moment, he did want to make sure he was decently pent up so that when they finally got to the actual sex he could give her the biggest load possible and he felt like he could handle something else before they both got impatient and needed to fuck, then he realized there was actually only one part of Marble's body that he had barely touched, her tits. Sure he had grabbed them a little but everything else, like her ass, her pussy and even her mouth had gotten to enjoy more than just a touch, to be fair he hadn't really fucked her ass though that was mainly just down to a lack of lube, which wasn't required for a half decent tit fuck. Confidently, Swift said "I don't suppose you'd be willing to pleasure me with your chest would you?"

Marble giggled and said "Oh, you wanna play with the girls huh?" Marble waved her tits from side to side enticingly, making them bounce and jiggle before she got on her knees at the edge of the bed and said "Well come on over big boy, let's get your cock all snuggled up and comfortable in between my soft and silky milk makers, then afterwards we can fuck like rabbits". Swift made his way to the edge of the bed and sat directly in front of Marble, who was holding up her heavy breasts, ready to sandwich Swift's cock in between them. When they were both in position, Marble adopted a seductive look and said "You ready?" Swift simply nodded and let out a hum of satisfaction as Marble immediately embraced his member into her warm cleavage. Marble started off slowly, rather than instantly sliding her tits up and down Swift's cock, she first just pressed her breasts together, squishing them up against his hard shaft and then simply rolling her breasts around from side to side and also back and forth.

However, with the energy the two had kept up all night, it was only a matter of time before Marble decided to move on from the build-up and onto the main event as she gripped onto her bust and started moving them up and down, giving Swift a proper good titty fucking. Swift grunted as he gave small thrusts in tandem with Marble rubbing her tits up against his rock hard erection, making the tip of his cock peek out ever so slightly from the top of her cleavage. Through the consistent plapping sounds of her big jiggly breasts colliding with his hips, Swift heard Marble's favorite and most effective turn-on technique, dirty talk. Marble looked at Swift with lidded eyes and said "Yeah, you like my tits baby? You like how these big fucking chest melons caress your thick throbbing cock? Mmm, I can feel how warm and needy your dick is in my cleavage, bet you wanna just jizz all over these fat titties huh? Make me look like a total fucking whore by painting my chest with your cum like I'm some kind of slutty porn star who moans and gets wet at the thought of the full thick load waiting for me, stored up in your heavy swollen balls that are aching for release, desperate to unleash everything all over me, or preferably inside of me..."

That was the last straw, Swift said "Baby, you better get on the bed because I need your pussy right now".

Marble grinned widely and said "Fuck yes! Oh fuck I need you inside me so much right now", she rushed over to her handbag and pulled out a condom, tearing it out of the wrapper with her teeth then quickly returning to Swift to get the slipppery latex cum container on his cock. As soon as the condom was on, Marble leapt on to the bed, got on her back and spread her legs to reveal her soaking wet pulsating pussy as she said "This pussy... fuck it, stick your dick in it and fuck it, ram that fucking veiny schlong into this cunt and make me scream!"

Swift chuckled and simply said "Gladly" as he moved in between Marble's legs. Not wanting to keep Marble waiting, as soon as Swift was poised at her entrance, he heaved himself forward and sank himself all the way inside her until his hips collided with hers, their reactions couldn't have been any more different. While Swift gave out a low guttural groan, Marble couldn't help but scream, it was so loud that Swift was certain that pretty much half the residents of Canterlot were now aware that someone was fucking. Marble wasn't any less quiet when Swift began thrusting, while he simply grunted as he repeatedly plunged his cock into her wet sex, she just squealed continuously like a girl being railed on prom night. Marble wrapped her legs around Swift's waist, squeezing and pulling on him to create more force behind Swift's thrusts, she raked the fingers of one hand through his hair while the other practically clawed at his back, leaving slight scratch marks.

Marble screamed louder than she ever had and pulled Swift's head into the crook of her neck, biting down on his shoulder to muffle herself as she came harder than she ever had in her life, her pussy muscles ached from the constant tensing as a ludicrous amount of liquid came bursting out of her pussy. Swift didn't last much longer and let out a loud moan as, with one deep hard thrust, his thick hot load began firing out from his painfully stiff cock. With every shot, Swift gave one thrust, in her dazed state Marble was surprised he had so much cum to give, it was only on his fifth and final thrust that he had deposited every last drop his balls had to offer.

They both collapsed with Swift still inside her, panting, sweaty and incredibly tired. They fell asleep almost immediately.

• the next morning -

Both of them woke up as the sun's rays flooded the room, as they came to their senses they both chuckled to see that Swift's cock was still entombed in her pussy and it seemed his body had seen no reason not to give him every man's early wake up call, the so called "morning glory". Swift went to pull out when Marble went "Wait! Since you're already... well, y'know... how about a little morning sex?"

Swift said "Are you sure? I can promise you it might not last very long..."

Marble smiled and said "Just do it, neither of us got to enjoy a proper afterglow last night, so let's have one now"

Swift just smiled back and said "Alright" as he began thrusting again, this time however the sex was a lot more passionate and slow, the noises they made were small gasps that barely rose above a whisper. A minute or so later, Swift's sensitive member pumped a fairly small load and although Marble didn't cum, they both got the warmth and comfort of post-sex afterglow they were hoping for. Swift pulled out, tugging the condom-turned-spunk-balloon out of Marble's nethers.

Marble peeled the condom off of his member and as she felt the large amount of cock cream resting in her palm she went "Hmm...... still warm......", without a second thought, Marble poured the thick load from the condom into her mouth and swallowed, licking her lips as if she had just taken a lick of a particularly tasty ice cream then discarded the empty condom into the nearest bin. Swift loved how dirty his girlfriend was.

Marble said "Well, I suppose we should start heading home, did you enjoy your birthday?"

Swift nodded and said "Yes, very much"

Marble smirked as she said "Good, oh and by the way, when we get home we are going to find Pinkie Pie again, we are going to have that threesome and you are going to ram your fat cock up my ass, what do you say?"

Swift simply kissed Marble and said "I'd say I am incredibly lucky to have you, let's do it!"

The End
