Flash With Benefits

Flash With Benefits
-by Drace Domino

It had been a bit of a rough year for Flash Sentry. First, the girl he was dating turned out to be some sort of evil horse girl from a horse dimension. Then, he managed to have a crush on a good horse girl from the same horse dimension. When the bad horse girl went good and the good horse girl went back to said horse dimension, a non-horse girl showed up that just happened to look like the second horse girl. Then, despite the fact that Flash was easily able to transfer crushes between horse and non-horse, that girl started dating the first used to be evil but was now good horse girl.

...it had been a rough, long year.

But it wasn’t all bad! He was still doing well in school despite all the mayhem that seemed to go down every couple of months, he was still one of CHS’ top athletes only behind Rainbow Dash, and on the romance front...well...that cute cross-eyed girl seemed to like him! Through it all, Flash Sentry had persevered and managed to stay standing, even though of all the students at CHS all this extra-dimensional horse nonsense always seemed to negatively impact his love life.

He was moving past it all - happy and content that Twilight Sparkle and Sunset Shimmer had found each other. They were cute as they darted through the halls together, having nerdy conversations and holding each other’s hand. Between the two of them techno-babble was akin to baby talk, and it chattered on almost endlessly when they were near each other. Flash was genuinely happy for them because, even after all that nonsense, he was still a hell of a nice guy.

Which was most likely why that day after school, he got a text message from Sunset Shimmer with a very blunt, very unexpected message.

“Hey, want to get your cock sucked?”

Flash had been walking home from school, and now he stared at the phone resting in his palm reading the text again and again. It was clear from his contacts that it was from Sunset Shimmer, not to mention the fact that the girl used a comma, a question mark, and proper spelling. Who did that with texts, anyway? Flash bit down on his bottom lip, and took a deep breath as his thumb began to sweep over the keys in response. It had been a long, long time since he got to feel Sunset Shimmer wrap her mouth around his dick, but...this had to be a mistake.

“this is flsh not twilight” He texted back, let his finger linger over the send button, and finally pressed it. He wasn’t jealous of Twilight Sparkle; per say, but he had definitely noticed that Twilight had something in common with him and Sunset - all three of them were hung. Not that he had been trying to look, but...well...when you were a teenager with flaring hormones, certain things were evident went the jeans were tight enough. It didn’t bother him that Sunset Shimmer was sucking on Twilight’s cock these days...but he had to admit, a part of him missed it. Hell, a part of him missed sucking on hers.

With a tiny sigh Flash tucked his phone back into his pocket and kept moving forward, eyes back on the sidewalk. Maybe it was time to ask Ditzy Doo out? She was sweet. She was adorable. As far as he knew she didn’t have a penis, but...they could work around that. Maybe. The young man didn’t get more than ten steps or a third thought about calling Ditzy before he got another text, and grunted as he fished his phone from his pocket once more. Fully expecting to read a half-hearted apology, what he instead found on his phone shocked him.

“Who do you think is going to help me, stud?”

Attached to the message was a picture - one of Sunset Shimmer and Twilight Sparkle, arms linked around each other’s waist and with clear intent. Both girls were dressed in outfits that could be called slutty only in the most understated of terms - Sunset with kneehigh leather boots, a matching corset that lifted her exposed breasts, and long gloves befitting a dominatrix. Twilight Sparkle was wearing what could only be described as an abbreviated schoolgirl outfit, with kneesocks, a short skirt that did little more than add a hint of plaid around her waistline, and nothing above it other than her glasses. Both girls had their cocks fully exposed and sticking out, and thanks to the magic of the high-definition image, Flash could even tell they had either been sucking on each other’s dick...or had been lubing them up for something else.

“...sweet ponies on a cracker!” The boy whispered to himself, dropped his bookbag, and rapidly began to text with both hands. His thumbs flew as his heart began to race, and the front of his jeans were already tenting.

“when and where please ill be right there!!!!!!!” Smiley emoji, wink emoji, smiley emoji, eggplant emoji. Hopefully he didn’t seem too eager!

Flash Sentry stood there on the sidewalk clutching his phone with both hands, his eyes wide and his heart racing as he waited to hear the reply. Even still, a part of him was trying to keep his expectations in check. Sunset Shimmer had always been a “dirty girl” during their time together, but...but this was something else entirely. It had to be a prank! A joke! A scam!

His heart beat all the faster as his hands tightened on the phone, and he saw dots at the bottom of the chat letting him know the response would soon be there.

***

...it was definitely not a joke. If Flash Sentry knew anything, it was that much. The young man groaned with a noise of profound pleasure as his head rolled back, and he spread his thighs just a little bit further to afford room for the girls to work. He had only just arrived at Twilight Sparkle’s house a few minutes ago, and already he was enjoying something he had dreamed about on plenty lonely nights since his breakup with Sunset. The two nerdiest girls in school were sucking his cock.

“T...Twilight, Sunset…” Flash whispered, his head lifting up so he could cast a glance towards them. In that moment Sunset Shimmer was holding his spit-covered dick by the base as Twilight bobbed her head up and down, taking his inches past her lips and sweeping her tongue wildly back and forth. Both girls were dressed just as they had been in the picture, and everything was even easier on the eyes up close - especially their pair of well-lubed, stiff cocks. Flash trembled with pleasure and moved his hands down to his shirt, slowly starting to lift it up and over his head while he spoke. “What...what the heck brought this on?”

“Twilight’s parents are out of town for a conference.” Sunset Shimmer smiled, and as Twilight kept working bobbed her head down to press a kiss to her girlfriend’s cheek. “We always wanted to introduce a third dick into the mix for some extra fun, and I knew you had a great one. We just needed to wait until we had the place to ourselves so we could really let loose.”

“...thanks for thinking of me.” Flash beamed at his ex-girlfriend, and reached a hand down to stroke his fingers through both of their head. The girls responded to it in their own way; with Sunset Shimmer pressing against his palm and Twilight Sparkle sucking cock all the more eagerly. Her eyes were shining behind the frames of her glasses as she worked, gazing up along Flash’s toned, exposed chest once he managed to get the shirt off. “When we were dating you always had, uh...a plan. A schedule.” He arched a brow as he regarded Sunset, and spoke in an almost worried tone. “...do you still do that?”

“Ha! No, I’ve calmed down some.” Sunset Shimmer beamed, and allowed her fingers to slip back into Twilight’s hair at the base of the girl’s neck. For the moment she took the offensive; pushing her girlfriend’s face back and forth, making her take Flash down as far as she could go. At one point she even pushed Twilight’s head forward so far that the girl’s purple nose touched Flash’s belly, and she held it there to make her nerdy girlfriend keep him deepthroated and throbbing while she spoek. “Some! I know I used to be a real demanding witch in bed, but I--” A soft pause, even as she kept Twilight’s head down and her throat stuffed with dick. “--you don’t want to argue that?”

“No, that’s accurate.” Flash merely nodded and smiled; taking almost as much pleasure from the look on his bratty ex-girlfriend’s face as he did from the deepthroat blowjob of the other girl. Almost. Sunset merely rolled her eyes and chuckled, and when she released Twilight’s hair from her grasp she began to slither forward on the couch. As she braced a knee against it and lifted herself to lean against Flash, the young man slinked one arm around her waist as his other hand invited itself to reach lower. By the time Sunset was pressed against him Flash was fondling his ex-girlfriend’s well-lubed cock, and Twilight had returned to a more reasonable pace of gentle, friendly cocksucking.

“Well, not tonight. You could say that Twilight’s broken me.” She cooed, even though that clearly wasn’t entirely accurate. She still dressed like a fiery dominatrix, after all! Still, Flash wasn’t about to argue as Sunset walked her gloved fingers up his chest, and leaned in dangerously close for a kiss. “Tonight, it’s a free for all with you, stud. Nothing off limits between the three of us. Every cock is in play and every hole is fair game. Sound good…?”

Flash looked from Sunset to Twilight, who was already working him towards his very first orgasm of the evening. He would’ve been a lunatic to refuse this moment even if Sunset gave him a strict schedule to work with, and so naturally the boy didn’t have a single complaint on his tongue as he looked back at his ex-girlfriend.

“Sunset, that sounds great.” He announced, and then followed it with an equally important declaration. “...and I’m going to cum in Twilight’s mouth any second now.”

There was no lie in his statement. No sooner did Sunset Shimmer look down at Flash’s lap did she see Twilight’s cheeks suddenly puff out, and Flash himself tensed in pleasure as his cock twitched, pulsed, and throbbed. Jets of his cream rushed against Twilight’s tongue as the nerdy young woman coped with it all, swallowing what she could while still managing to keep a nice, healthy mouthful contained. When Flash’s length finally calmed Twilight Sparkle was careful and critical as ever - slowly pulling Flash’s cock from her lips and keeping her lips sealed tight. She crept up onto the couch on the opposite side from Sunset Shimmer, and as she did so Sunset lowered her hand to fondle at Flash’s sensitive, softening, but still young and eager dick.

“...well, maybe I did plan a few things.” Sunset murmured in coy fashion as Twilight Sparkle moved to trap Flash between them; bookending the young man in hot, teenage flesh eager to throw down in a lusty and wild threesome. Twilight Sparkle was beaming as she drifted close, squeezing her bare breasts to Flash’s chest and looming ever closer with her cheeks puffed out with a mouthful of thick, tasty cum. Sunset leaned in at the same pace, and Flash gave a gasp of delight as he realized just what was about to happen. The only words that came before the messiest and most intense kiss of Flash’s life so far were those of Sunset’s whisper; each one laced with erotic joy from the dirtiest, sexiest woman he had ever known. “Open up, Flash…”

What followed filled all three of them with glorious delight. Flash’s hands had moved down to fondle the asses of each girl; squeezing his fingers tight into Twilight’s purple rump while the other helped itself to Sunset’s. With both women pressing against him Flash savored a creamy, cum-coated kiss that filled his mouth with flavor - the taste of his own seed as licked and slurped from the lips of the two girls he had harbored crushes on in the past. Breath was shared between the three hot and heavily, and while any two sets of lips were locked another pair moved back and forth, kissing away stray strands of cum and eager to steal the moment. Sunset held her girlfriend and ex-boyfriend close, Twilight gladly offered up the heaping mouthful of cum she had earned, and soon both girls were letting their hands explore everything they could. Each other...Flash...anything they could manage to touch.

Flash Sentry’s cock had stiffened considerably as the two girls kissed him with that creamy treat, but even though he was hard enough to go again he wasn’t able to steal all the limelight. As the kiss weaved between them Flash let his head sweep to the side, letting Twilight and Sunset kiss as he moved his mouth to the purple girl’s ear. There he offered her a tiny whisper that Sunset couldn’t hear - though Twilight Sparkle seemed eager to obey.

“...that’s a wonderful idea, Flash.” Twilight giggled, and quite readily started to stand up. Sunset was left missing the kiss of her girlfriend, but it didn’t take long for her to realize just what was happening. Soon Twilight stood on the couch cushion; balancing against the wall as she offered her thick purple cock up between the other two. It was heavy, surprisingly thick, and glistening with the lube they had coated it with...though it could always go for more.

“I’m so glad we stayed friends, Flash.” Sunset Shimmer beamed as she slipped her hand away from his cock up to Twilight’s, and gave him a devilish wink. “Close enough that we can suck my girlfriend’s dick together.”

“Any time you like.” Flash beamed in response, and moved forward to do just that. With the taste of his own cum still on his tongue he moved with Sunset to suck on the purple cock offered up to them, tongues sweeping forward and slipping underneath the tip of her sensitive length. Flash and Sunset wiggled those pink muscles back and forth as they drew in the taste of the lube - the same sweety, flavorful goo that Sunset used back when they were still dating. Knowing Sunset and her meticulous mind, that was no mere coincidence. She wanted her ex-boyfriend to feel comfortable in what could potentially be an awkward threesome.

“Ohh...w-wow, you two...that’s...woooow…” Twilight Sparkle trembled as her cock was sucked, and she let her hands glide down to press against the back of their heads. She rocked her hips from side to side and gladly let them share her length, watching with blushing joy as Sunset dipped her head down to start greedily sucking at her purple balls, only for Flash to bob down a split-second later and join her. With both of them working to pleasure her undercarriage Twilight’s cry rose even sharper in the room, and one of her eyes twitched behind the frames of her glasses. “S...So good! You two are...hnnn…!”

Sunset Shimmer winked at Flash while the two kept working, pleased that Flash’s willingness to suck on a plump, lovely girldick hadn’t faded since they stopped dating. She rewarded him by moving her free hand down to fondle him a little further; doing her best to mimic the pleasure to his balls that they were bringing Twilight’s. From time to time she even let her lips cut a sharp corner to give him a hungry kiss, and more than once it was delivered with Twilight’s throbbing tip trapped between their lips.

Twilight Sparkle’s knees trembled, and the young lady’s face went dark with a blush that darted like wildfire across her. She was breathing heavy, her small chest was rising and falling, and it was easy to see that they were racing towards the second big climax of the evening. Mere seconds before her moment came Sunset gazed to Flash with that plotting smile once more, and licked her lips as she slipped her hand to the back of Flash’s head.

“Watch this, stud.” She cooed, and moved to trap her mouth around Twilight’s tip just as she pushed his head forward, making his mouth meet her balls. Flash was left moaning with his mouth pressed flush to Twilight’s sack, his tongue sweeping back and forth as he could actively feel her trembling on his lips. Twilight Sparkle’s adorable cry of release filled the room around them, and just like the nerd before her Sunset Shimmer’s cheeks started to puff out from cum. She gulped down only the minimal amount while preserving all she could, and by the time she let Twilight’s tip leave her lips there was still a squirt for Flash to enjoy. Just a squirt! A sweet taste, and he was sure to get more later.

What came next convinced Flash more than ever that even though this evening was something of a free-for-all, Sunset had planned every step. Or at least...the first few. She was moving too confidently not to have, and everything was going according to her plan. Twilight Sparkle took over controlling the back of Flash’s head; guiding him to look down at his own lap and that thick, spit-covered, pulsing dick waiting for attention. He trembled when he realized just what was coming next, with Sunset Shimmer pulling her head down and leaving her eyes meeting his own.

“...S...Sunset...you…”

She was. While keeping full, passionate eye contact with her ex-boyfriend, Sunset Shimmer opened her mouth and rolled out her tongue, unleashing Twilight Sparkle’s load all over his cock. The wet warmth that started to coat his length was truly a joy, though the pleasure of it paled in comparison to the visceral display before him. Sunset was pouring her girlfriend’s cum across his cock like she was frosting a cake, letting it all glaze his member in a thick white veil. And then, without a single word of explanation, she spun around and got onto her hands and knees right in front of the couch. She braced herself there with thighs spread and her amber-skinned ass exposed; stiff cock hanging between her legs and that tight, rear pucker glistening. She was already lubed - and now thanks to Twilight’s cum coating, so was Flash.

“Fuck my girlfriend in the ass, Flash.” Twilight whispered after crawling back down to the couch, pressing against him and giving him a tiny kiss. Just as soon as she did she bounced off his lap and down to the floor, bracing herself on hands and knees right beside her girlfriend. With a glance over her shoulder Twilight beckoned him over, wiggling her purple rump and letting her cock slap back and forth between her thighs. “And then fuck me, too! We’ve got all night!”

Flash Sentry’s throat tightened as he gazed at the pair of asses before him - each ripe and ready for the taking. His own cock was as hard as it had ever been, coated in a glaze of Twilight’s cum.

...dealing with all that horse dimension nonsense was suddenly worth it in a big, big way.

***

Between Sunset Shimmer and Twilight Sparkle, Flash wasn’t sure which ass to cum inside! Good thing he had all night to make sure to try them both out. As Flash dropped to his knees and slid his cum-covered cock inside of Sunset Shimmer, it was like a trip down memory lane...even though in the old days, Sunset didn’t let him be the one doing the thrusting all that often. Back then she was usually always in charge and always demanding pleasure, using either of Flash’s holes until she was finished. Sometimes, she didn’t even help him cum! Truly, the girl had undergone one hell of a change now that she had discovered friendship with Twilight and the others.

As Flash fucked her from behind Sunset leaned to the side so she could kiss her girlfriend, and the two girls were murmuring sweetly to each other as Flash drilled himself into Sunset’s amber hole. Twilight’s cum ensured that Sunset was getting a creampie from the very first thrust, and the heavy dose of lube ensured that every push forward was warm, wet, and filled with nothing but thrilling sensations for Flash. After a few moments of hammering away at his ex-girlfriend’s ass Flash quickly shifted over; letting his cock pop out of her rear as he turned to Twilight, moving his hands to take her waist and slapping his prick against her purple rump.

“...I can’t even tell you how much I’ve wanted to try this one.” He murmured, mere seconds before lining himself up and thrusting inside. Twilight, just like Sunset, was wonderfully responsive as she was assfucked by the young stud. Her cock throbbed and twitched as he fucked her, and when she wasn’t kissing Sunset she was looking over her shoulder begging Flash for more. Her hole offered him the same warm and inviting grasp as she tightened her rear around his length, and when Flash popped out of her in order to move back to Sunset she even gave a little pout.

“Aww…” She didn’t have anything to really pout about - there’d be plenty of cock for all of them to go around by the time morning came.

Flash ended up cumming inside of Sunset Shimmer when presented with the option, launching his hips down to the base and letting his prick pulse with waves of hot, creamy spunk right into her rear. Sunset howled in delight as she was filled, her muscles tightening and her rear squeezing his shaft in tense, milking grasps that begged for more and more. By the time Flash was finished Twilight had already moved to pull his dick from her rear, and after giving it a tiny slurp with the tip of her tongue immediately turned to press her mouth against Sunset’s ass and start sucking out every last drop.

“Ohh...oh Twilight, yes…” Sunset shuddered, her own dick throbbing and twitching - the only one of the three of them that hadn’t yet cum, and so very, very eager to do so. “...g...get in there deep…”

Flash Sentry merely stood back and wiped the sweat from his brow, watching as Twilight so eagerly ate her girlfriend’s ass. It was touching to be invited into the mix that night, and when Flash spoke up once more he did so with a charming smile and his hands stretched out.

“Twilight? Wanna show us to your bedroom?” He asked, offering his grip to both girls to help them up. “I think we need to get Sunset Shimmer off.”

The night just kept going in that fashion, with the three lovers enjoying each other’s body without any restraint or hesitation. Once they were safely in Twilight’s bed Flash Sentry moved to brace on his hands and knees, and he made the girls the same offer they had to him - a nice, tight ass to use in order to get them off. In a joyful reversal of the past session Twilight and Sunset kept taking turns fucking Flash’s rump, though Sunset Shimmer couldn’t go for very long before she had to keep pulling out - holding back her climax, knowing that only a few wet, warm thrusts could push her over the edge. Flash wasn’t sure just why she was holding back, but...that didn’t stop Twilight from filling his ass with cum, or him from enjoying it!

It was almost a full hour later and Flash and Twilight had found their peak several times over. The naked teenage stud and the schoolgirl-clad nerd had enjoyed their fair share; cumming not only in each other but in Sunset Shimmer several times. Whenever Flash spoke up about getting Sunset off the girls seemed eager to distract him or change the topic; usually by Twilight thrusting her dick into Flash’s mouth or both girls suddenly dropping down and sucking him off. Finally; though, Flash needed answers.

“T...That’s...whew…” Flash was still catching his breath from the antics that took them over the one hour mark - sixty-nining with Twilight Sparkle while Sunset kept rolling them over and eating the ass of the one on top. It had led to Flash and Twilight pumping plenty of cum down each other’s throats, and his face was still marked with spit and Twilight’s cream as he pulled himself up to his knees. He smiled as he looked at the pair of girls, from Twilight’s spent figure to Sunset Shimmer’s leather-clad form - her amber cock still rock hard, looking almost painfully tense and aroused. “Hey...Sunset, let’s do something for you already. Please?”

Once more the question was presented between the three, and once more Flash could see the flicker of hesitation. Sunset looked nervous, tense, nibbling on her bottom lip. It only took her a second before she spoke up, and started to spin around as if to present her ass.

“H-Hey, I have an idea! How about...how about you two take turns fucking me?!” She asked, swinging her rear from side to side. Cum was oozing out of her hole - they had both already taken turns. It wasn’t until Twilight Sparkle finally spoke up that the truth was ready to be unleashed, the nerdy young woman’s nose scrunching up as she grabbed Sunset’s wrist and pulled her back into place.

“Sunset, enough!” She scowled, and gestured to their mutual friend. “Flash is our friend! You have to get over this!”

“...Sunset?” Flash blinked, arching an eye and resting back on his knees. All three of them stood there with hard cocks and glazed with sweat, nectar, and juice...yet the heavy stench of sex in the air didn’t diminish his concern. He put a hand to Sunset’s shoulder, coaxing her attention. “Something you’re not telling me?”

“I...I just…” There was emotion on her face; trembling, almost whimpering. For the chief orchestrator of a thrilling threeway, she looked far too upset. She didn’t want to be honest in that moment, but unfortunately Twilight was forcing her hand. “Flash, I just...back when we were dating, I was so selfish! I was so mean to you! I always fucked you and I made you jerk off without me, and...and I liked teasing you, and...oh, I was a horrible girlfriend!”

Flash Sentry merely blinked. It wasn’t the confession he was expecting to hear; nor the apology he ever planned on receiving. Sunset was nearly on the verge of tears as she spoke, and Twilight Sparkle patted her girlfriend’s shoulder to console her. It wasn’t until Flash spoke up; however, that Sunset’s head finally lifted and her trembling ceased.

“Sunset? I had a great time with you back then.” He smiled, stepping in close enough so that his cock joined the pile - the three of them touching tips back and forth while he spoke. “Sure, you were a little...demanding, but they were still good times. If there’s anything to forgive, it’s forgiven. And…” He quirked a brow, and gazed to Twilight before back to Sunset. “...right now? Twilight and I think you’re being pretty selfish by not giving us your cum.”

“Mhmm!” Twilight chirped up, grinning widely at her girlfriend. She was leaning against Flash, and her cock just happened to be the middle of the three-dick sandwich at their laps. “So what do you say, Sunset? Gonna stop being selfish?”

Sunset Shimmer - a tear in her eye and a blend of two people’s cum oozing from her ass, looked fondly at the other two. How could she be so lucky to have such a great girlfriend and such an understanding ex?

“I...really want to cum inside of Flash while Twilight fucks me in the ass.” She admitted her wish, with a healthy blush on her face.

Thankfully, they would be more than happy to make that wish come true.

***

It was late, late in the evening before the girls finally fell asleep. Flash laid in the middle of Twilight’s bed, holding an arm around each of their shoulders and happily letting them fondle him - and each other - in their sleep. One hand was on his cock while the other was on his balls, and there was a genuine delight in not knowing who was grabbing what. He stared blissfully up at the ceiling of Twilight’s room - marked with glow-in-the-dark star stickers that were absolutely astrologically accurate in placement and size. The room was utterly filled with the scent of their combined lust, and Flash Sentry drank it in gleefully, savoring each and every breath.

Together, the three of them did just about everything they could imagine...and he knew that in the morning they’d probably think of a dozen new ways their bodies could intermingle. He tightened his arms around both girls and relished in every last sensation in that moment - the scent, the feel of them against him, the cum that still filled his ass and seemed to churn with every breath, and the soft drip, drip, dripping of their flaccid girlcocks leaking tiny bits of cum against his thighs. It was a moment of pure joy and utter delight for Flash Sentry - the apex of a perfect evening with his favorite couple.

Maybe tomorrow night, he’d ask that adorable cross-eyed girl to go to a movie. And maybe next time Sunset invited him over, they could make it a double date.

The End.
