Silver's eyes locked onto the double-ended adult toy next to her marefriend Scootaloo on the bed, her nether winking rapidly in need at the sight of even a faux stallion's cock. "Wow, that's...a pretty big one." Silver said, noticing that the dildo's girth and length surpassed her own eight-inch dildo by at least three inches in length and one inch in circumference, the medial ring on it much more pronounced as well. She felt a tinge of nervousness given it was so much longer and a third thicker than what she was used to, but her lust overwhelmed it more. She needed something inside of her, and that pseudo-cock certainly fit the bill. "But...I kinda wanna do something else first..." Silver said as she got another idea instead.

"Oh yeah? What's—" Scootaloo started, only to find herself tumbling onto her back from a force pushing her back. Atop her lay Silver, who had knocked her over, grinning impishly and getting a roll of the eyes from Scoots. Silver squirmed closer, Scootaloo watching as their crotches shifted closer, her breathing quickening in anticipation. Silver angled herself as Scootaloo helped by lifting her own rump and back leg. As their pussies soon met, both mares gasped at the sensation as their clits simultaneously winked in response to the stimulation. As their two sensitive nubs kissed, each gave out a soft 'aah!' of pleasure, their hips instantly, instinctively starting to grind against their mate's.

"Oh my Celestia..." Scootaloo groaned, feeling a mix of Silver's and her own fluids drooling down onto her leg and bed, suffusing the sheets with the scent of heated mares.

They scissored like that for a good long while, their pussy grinding against their lover's, clits winking occasionally and only adding to the sensation as they met in a kiss of their own. Scootaloo kept trying to take control of the act, but Silver's position gave her more leverage, plus with her being an Earth Pony it gave her a natural advantage of physical strength. Each time she tried, Silver gave a cheeky grin and ground especially hard the next time, making Scoots whimper in pleasure.

So instead of overwhelming her mate in pure brawn, she instead used her own natural Pegasus dexterity and appendages to her advantage in getting the upper hoof. Scoots slid a sneaky wing down to Silver's and her own joining, hearing a sharp inhale followed by a whimper as she started rubbing Silver's clit with her thick pinion feather.

"Scoots...I...I..." Silver stammered after only a minute more of this, before grinding especially hard once more with a sharp inhale, Scootaloo feeling Silver's pussy convulsing and winking rapidly as a torrent of fluids and a cry of passion came from her. Scootaloo felt as her lover's grinds were saccadic and twitchy as she shivered, grinning as her mate clearly came hard. She kept her feather doing its tickling rubs in sharp circles, only stopping when Silver started whimpering at the clear overstimulation.

Eventually, Silver slowed her grinds, giving Scootaloo a dirty look. "W-wings...are...cheating..." Silver gasped out once she'd caught her breath, only getting a sly grin from her lover.

"All's fair in love and war..." Scoots replied, sticking out her tongue. It was her turn to be surprised as Silver leaned over and licked her tongue, sending a surge of sensation down her spine and reminding her of just how much she needed release herself. "Right, so, I'm super horny now...let me get that dildo on. I bought this one special, just for us. It's built so both mares can get pleasure." Scoots indicated that one end was a normal dildo, while the other end curved upwards into another, somewhat smaller phallus.

"Wait, you planned this? Getting me drunk, then..." Silver asked, feeling a bit manipulated and hurt. Diamond Tiara had tried this once...

"Nah, whoa, it's nothing like that!" Scoots explained in a bit of a panic, "It's just, I knew we'd want to have 'relations' eventually and I figured it'd be either after we got married or...possibly during our heats, and I wanted to be prepared." She then placed a hoof on Silver's cheek, "I promise, I'll never manipulate you into doing something you don't want to."

"I know..." Silver said, giving a bashful expression, "...sorry, I'm being a dummy and hormonal. Damn heat. Besides...I kinda wanted this eventually either way."

"That's OK," Scootaloo said, giving another smirk, "cuz you're my dummy."

Silver smirked back, before rubbing noses with Scoots. "Love ya babe. So...shall we? I can't wait to feel that in me." Her smirk then faded, "But wait...aren’t you still horny? I've cum four times, and you've only gotten one. I mean, I want to please you too..." she said, before feeling a hoof land on her shoulder.

"Hey, it's OK. I want tonight to be all about you, alright? My heat isn't that bad after I came, and I want you to be as happy and satisfied as I can make you." Scootaloo replied, giving her a kiss, "You just worry about you now, and you can worry about me later or tomorrow when I feel worse, alright?"

"OK..." Silver said skeptically. She wasn't used to being showered with attention like this. When she and Diamond Tiara were briefly dating, she was always treated second-rate, Diamond expecting to be treated like a princess while she gave no such treatment in return. Scootaloo...Scootaloo was the complete opposite, always focusing on Silver's wants and needs before her own. "I swear, I'll pay you back for this later."

"Don't worry about it. Just relax..." Scootaloo said, having been putting on the strap-on harness during this time, moaning softly to herself as she felt the curved end of the dildo slide easily into her very ready vagina to the base, Silver hearing a soft 'snap' as the dildo was attached to the harness, "...and let your mare take care of your nasty little heat."

Silver gave a little eager whimper as she looked at the long, thick, black dildo attached to her mare's body, imagining that instead it was a real cock, the one Scootaloo said that certain spells or potions could give a mare. Her mind was saturated in hormones, the strong urge to reproduce bringing the thought of foals to her mind; how cute a foal made by her and Scootaloo would look chief among them. Before she knew it, she'd lifted her rump up off the bed while her upper half remained down, her tail swishing to the side, flagging to the mare standing on the bed behind her. "Please...I want your foal." Silver said, giving Scootaloo a wink.

"Ah, so you are into that kinda stuff, huh?" Scootaloo asked, giving a smile, "Well in that case..."

"...I'mma get you pregnant with triplets."

Scootaloo mounted swiftly, Silver moaning deeply as she felt the weight on her rump and grinding on her croup, pushing up her hips instinctively to the 'stallion' to show her eager willingness to be bred by him. Her clit was winking constantly, spreading her wetness all over her vulva to make penetration easier, her back arching up for the same.

"You're not a total virgin, right?" Scootaloo asked, getting a nod from Silver.

"Yeah, I've used a dildo before during my heats and broke my hymen during my first like most mares, and have done some rubbing with my hooves too." Silver said, before her blush grew deeper, "You're my first pony though."

"Really?" Scootaloo asked, a bit confused, "But Diamond said..."

"Let's not talk about Diamond now, OK?! You're my first, no matter what lies she told!" Silver snapped with a little more force than she intended, wincing and looking repentant after. "Sorry about that...but can we just focus on us right now?"

"No, it's my fault...I know how you and Diamond were. Lemme make it up to you." Scootaloo said as she lined up the dildo with Silver's winking slit, the feeling of the toy's flare on her entrance making Silver let out a shuddering breath.

"P-Please do." Silver said simply, then moaned deeply as Scootaloo shifted her hips forward slowly, easing her way into her marefriend before hilting easily soon after.

"N-No need to go slow! I'm beyond r-ready! R-rut me as deep as you can!" Silver instantly demanded despite the size of the pseudo-cock penetrating her as Scootaloo's first thrusts were slow, shallow and sloppy, much to Silver's displeasure. "Breed me!"

"One breeding and foal, comin' up!" Scootaloo said, feeling the curved portion of the dildo shifting inside of her own passage with each thrust, helping to sate her own pleasure needs as she rutted her mare's pussy. Silver quickly devolved in a whimpering, squirming mess as Scootaloo gave hard, full-length thrusts into her, soothing her body by giving it exactly what it needed.

This wasn't the passionate, loving first time Silver always dreamed it would be, but she wouldn't have it any other way, her estrus demanding to be satisfied with a good, hard rutting. Demanding to be bred by her 'stallion'. Silver knew what Scoots had said about her getting a foal from this obviously wasn't true, but her body reacted to her words almost as much as the thick slab of black silicone inside of her, pleasure bubbling up ever higher as her hips rocked back into each hard slam into her, yet something else came to mind. "S-Scoots, stop please..." Silver whimpered out despite her entire being telling her not to.

"S-Silver? I'm not hurting you, right?" Scootaloo asked, her humps instantly stopping. She felt Silver still gripping the dildo inside, her muscles kneading and clit winking, but she wanted something else.

"N-nah, you're doing so good...I just...I kinda..."

"Yeah?"

"I want it...up my butt."

"Sorry, what?"

"I SAID I WANT THAT THICK DICK UP MY PONUT!"

Scoots was a bit taken aback by the vulgarity but complied with a chuckle, sliding that long dildo out of her pussy, aimed higher, and placed the wide flare at her lover's ass. Silver moaned, trying to loosen her tight sphincter as Scootaloo eased it in, the feeling different yet similar to when it had been within her foal-passage, if a bit more uncomfortable. "T-That's goooOOood..." Silver cooed, pushing back into the thrusts.

At hearing her asking her to step it up, Scootaloo nodded as she slid out again, then let her hips move at a more moderate pace against the tightness of Silver's rectum, the wet smacks of their crotch and ass meeting resounding through the vaulted ceiling of the bedchamber now, Silver's louder moans and Scootaloo's grunts of effort and pleasure joining them in a cacophony of sated desire.

"S-Scootaloo... yes-yes-y-yeeees!" Silver moaned out, then gave a quiet yelp of surprise at the sudden, intense sensations that Scootaloo's dildo being plunged deep into her ass caused, but she was by no means protesting. She started to give quiet moans as she was held in place around the barrel, feeling that wonderful pseudo-cock once more buried deep, bringing her close again to the peak of her summit. It wasn't long after, with pleasure flooding her senses and the feeling of pleasing fullness coming from below, before Silver finally could take no more.

Not even able to give a warning, Silver moaned deeply as she tensed up, her hips starting to instinctively grind against Scootaloo's crotch and painting it with the profuse off-white fluids that she squirted out all over Scootaloo's crotch and the bed behind her, cumming hard as she released her day's frustration. She felt as her whole lower body convulsed with each contraction, feeling Scootaloo remain deep inside of her and only gently humping now, giving her powerful muscles something to squeeze and milk while Silver gripped a pillow as an anchor, trying to keep herself from getting lost in the ocean of bliss she was nearly drowning in.

Finally after what felt like days, but could only have been mere seconds, Silver slumped limply upon the bed, still occasionally trembling as her body recovered from such an intense release. "Mmm-mmm..." Silver moaned softly after recovering for a couple minutes, "...by Luna, that was wonderful..."

"Mmmmhm..." Scootaloo cooed in response, feeling as Silver rolled off of her and instead held her in a hug, with Scootaloo crawling up burying her mare-cum-soaked muzzle into her lover's neck. "Celestia's holy dick, I'm bucking soaked already and I haven't even cum myself yet!"

"L-let's fix that then, shall we?"

After recovering from being a twitching, cumming mess, softly kissing Scootaloo the whole time, Silver stood and took the harness off of Scoota with her help and cleaned it. After putting it on herself, she soon mounted Scootaloo and slid into her very ready marehood. Then, after only a couple of minutes of rough, sloppy humping, she felt Scootaloo having a massive orgasm; feeling the contractions trying to suck the dildo deeper into herself as Scoots trembled and whimpered, Silver letting her lover have her own mind-blasting pleasure after so long of only getting small tastes.

"I l-love you..." Scoots weakly said after she herself recovered, cooing softly as she nuzzled into Silver's neck and cuddled with her lover.

"I love you too." Silver replied, softly ruffling her mare's mane playfully.

Silver, before falling asleep, considered going to Scootaloo's zebra friend Zecora to see if what she said about there being a potion to turn mares into stallions, or at least partially, for a while is true. Thinking that perhaps in this fertile time, they could add a little foal to their family, or perhaps two at once if Scootaloo was willing. Silver smiled at the thought of her love and herself being pregnant at the same time with the other's foal, before finally sleep claimed her.

Both were soon fast asleep in each other's embrace, spooning together and eagerly awaiting the next day’s morning sex. After all, they had multiple days of their estrus to share together still, and possibly in time a foal or two to share as well.
