The unfortunate side effect of Fluttershy deciding to enjoy herself more as her orgasm began to approach, was that Twilight somewhat lost her concentration and the grip she had on holding back her release began to slip, eventually she couldn't handle it anymore and grabbed onto Fluttershy's hips and held her still as she began to roughly thrust upwards as deep as she could into her pussy, her hips a blur as she furiously pumped Fluttershy's fuck hole with her hips colliding with her smooth unblemished and jiggling ass cheeks.

Fluttershy let out a noise that was both a mixture of surprise and ecstasy as Twilight started to give her a good pounding, bringing her about halfway towards her orgasm. It was not to last however, as the constant impact of flesh on Twilight's pussy, even through the fabric of her pants, was having a profound effect and she let out a guttural groan as she hilted the strap-on in Fluttershy's baby factory, soaking her panties with her female fuck fluids. As they both got their breath back, Twilight blushed and said "Sorry babe... I was uh... a little quick there huh?"

Fluttershy chuckled as she stood up, removing herself from the strap-on and said "Oh don't worry, I'm sure you can make up for it...", Fluttershy turned around and pushed Twilight onto her back before clambering on top of her, roughly shoving the strap-on back into her aching cunt, ready to give Twilight a ride until she got to finish as well. Leaning down to draw Twilight into a deep and passionate kiss, Fluttershy let out a sigh of contentment shortly before beginning to piston her hips up and down, fucking herself on the faux phallus. While Twilight was enjoying this, she thought it was unfair that Fluttershy was doing most of the work and decided she needed to get back into control again, with a smirk she broke the kiss and using a surprising amount of strength forced Fluttershy to roll over so that their positions swapped before reunited her lips with Fluttershy's and beginning to thrust down into her sopping wet pussy as Fluttershy crossed her legs behind Twilight's back. Twilight sped up, ramming into Fluttershy as much as possible to bring her to orgasm, putting every ounce of force in her body towards the effort of having as much power behind her thrusts as possible.

Both of them were sweaty, out of breath and making various noises of pleasure that were muffled by the two of them refusing to stop tongue-wrestling, Fluttershy thought she was about to lose her mind with how good she felt when her orgasm somewhat caught her by surprise and she tensed up her leg muscles, stopping Twilight from pulling out as her vaginal walls clenched as hard as they could as if, in a vain attempt, to milk the strap-on for any spunk it could deliver as liquid squirted out around the intruding cock facsimile. When they both calmed down, Fluttershy released Twilight's waist from the vice-like grip of her thighs and allowed her to pull out as she practically collapsed on her back next to her. When they were both recovered from the exhaustion of rough animalistic fucking, Twilight simply said "You do know that we're not finished yet... right?"

Fluttershy nodded and said "Babe, I did notice the lube and paddle, considering you know that I like butt stuff I'd be pretty pissed if you didn't use those things", Twilight chuckled, she loved how in the bedroom Fluttershy went from shy and demure to cranky and lustful in a matter of seconds.

Twilight got off of the bed and went "Alright bitch, get up off your fat ass and bend over the bed, I wanna punish my naughty bride before I fuck her again", Fluttershy giggled and immediately did as Twilight demanded, keeping the dress resting on the small of her back as she stuck out her butt, ready for Twilight to make her move. Twilight didn't waste any time as she picked up the paddle and began to teasingly glide the length of it against Fluttershy's buttocks, she knew Fluttershy loved having her ass played with both inside and out, though she liked to make Fluttershy beg for it because she knew Fluttershy was always so embarrassed having to ask Twilight to indulge her in that particular kink.

Fluttershy whimpered as she felt the paddle tenderly caressing her skin, this wasn't what she wanted and she knew that Twilight wouldn't do it until she actually said so, "Please... please Twilight d-don't tease me... just fucking do it..."

Twilight played dumb and said "Do what? What is it you want me to do? I can't do it unless you tell me what it is......"

Fluttershy blushed and whispered "Spank me..."

Twilight rolled her eyes and said "You wanna speak up there honey?"

Fluttershy again, slightly agitated went "Please... please spank me..."

Twilight said "Louder you whore!"

Fluttershy, now getting really impatient finally gave the satisfying answer Twilight was looking for as she went "For fuck's sake just fucking spank me already! Punish me! I'm a dirty disgusting filthy slut and I deserve to be taught a lesson for being such a bad horny girl, now spank me!" Twilight smirked and swung her arm back before bringing the paddle smacking up against Fluttershy's soft defenseless rear, Fluttershy let out a small squeak before groaning as she felt the slight stinging sensation on her skin and saying "Oohh yeah... that's it motherfucker, give it to me good, fuck this is so hot and I'm so fucking wet, I-Aah!"

Fluttershy was silenced when Twilight once again clapped the paddle up against Fluttershy's cheeks and said "Shut the fuck up and take it...", the next few minutes continued with the only sound being the great thwack of the paddle against Fluttershy's sore cheeks and the small whimpers of painful pleasure, it was on the eleventh hit where Fluttershy's butt was burning bright red and she was close to orgasm that Twilight decided to stop, she could feel her pussy was moist and aching, it wouldn't take much to make her cum. Twilight said "So... ready for something a little more intrusive in your back door?"

Fluttershy shook her head and said "No... just one more, one more spank then I'll be ready..." Twilight shrugged and granted her request, giving a final and very hard smack against Fluttershy's bottom with the paddle, Fluttershy clenched her fists and grunted in discomfort as the orgasm that had been building in her groin was almost forcibly triggered and was nowhere near as pleasurable a sensation as it should have been. Twilight discarded the paddle and picked up the lube, unscrewing the cap and pouring a good amount out onto her hand.

As Twilight began sliding her hand up and down the strap-on to get it as slick as possible, she simply said "OK babe, ready for your fucking?" Fluttershy just nodded and took the initiative by crawling onto the bed, laying her front half down and reaching her hands back to spread open her ass cheeks as wide as possible, her tight pucker on full display and winking in anticipation of getting a good stretch. Twilight licked her lips as she saw Fluttershy presenting herself so explicitly without a single trace of shame, she got herself into position behind Fluttershy and buried her face in between her cheeks, applying long drawn out licks and kisses to her tight ring before spreading the excess lube on her hand around it, making sure to work a finger inside in preparation for the much larger item that she was going to insert inside her beloved girlfriends rump. Twilight pressed the tip of the strap-on up against Fluttershy's rear entrance and, after some considerably hard pushing, was able to squeeze the tip inside before sinking at least the first half of an inch inside.

Fluttershy let out a breathy gasp, the feeling of something entering her ass never got boring and she was never sure if she preferred it over vaginal intercourse, both were excruciatingly pleasurable in their own unique way. Twilight leaned forward and grabbed a hold of Fluttershy's tits as she continued to slowly slide the strap-on into Fluttershy's ass, grunting as she said "Damn babe... for a girl who loves anal, you sure are fucking tight..."

Fluttershy made similar noises as she said "Well... nng... maybe y-you should... ah... oohh fuck my butt mmm-m-m-more often if you w-wanna... damn... fucking stretch me out... shit this feels good..."

Twilight's hips finally met Fluttershy's buttocks as the last few centimeters of strap-on cock were lodged firmly in Fluttershy's ass, Twilight chuckled and kissed Fluttershy's neck before saying "Well... I never said being tight was a bad thing, don't want you too loose, where would be the fun in that?" Twilight pulled back until she was halfway out and then almost instantly surged forward again, plunging the strap-on all the way back in, once again the clap of her hips against Fluttershy's butt made a satisfying jiggle, Twilight squeezed Fluttershy's massive rack harder as she began fucking in earnest. Both of their were shockingly moist, Fluttershy's pussy was lubricating itself so much that her juices were started to flow down her thighs, Twilight's panties were equally soaked possibly to the point where she might have to throw them out rather than simply washing them.

Fluttershy finally let go of her ass to instead play with her pussy, which only allowed her fat ass to wobble even more and consequently make Twilight feel the need to fuck faster and harder with every passing second. Minutes went by with the two of them getting sweaty and exhausted but neither one daring to stop increasing the pace, things finally came to a head when Twilight gave one final thrust and held herself there as she cried out in orgasm, her pussy was again falling prey to the simple sensation of a beautiful booty sending vibrations through her crotch, not even two seconds later Fluttershy gave a similar squeal as her pussy practically gushed an absolute tidal wave of female fuck fluids onto the bed below, her whole body seeming to quiver from the ordeal. As they both calmed down from their final bit of sex for that evening, Twilight went "So... think you'll wanna do this kind of thing again?"

Fluttershy giggled and said "Maybe... but on one condition......"

-a few months later-

Fluttershy was leaning up against the bedroom wall wearing a white tux, admiring the view of Twilight on her knees in a black wedding dress eagerly attempting to get the strap-on Fluttershy was wearing into her throat. Truly, nothing says love like wearing the clothes your parents wore on their wedding day and having kinky sex in their bedroom.
