Happy Birthday To You

What a day. Today has been the best birthday you could ever hope for. The gifts you got from each of your friends was pretty amazing. The food was delicious, the music was lit and everyone else had a wonderful time celebrating your big day and now, everyone was leaving. The first to leave were the Rainbooms, your bestest friends since Canterlot High. Your other friends were the Crystal Prep girls. Despite the fact that they came from a rival school, they still made for some pretty company all in all.

Then, of course, we have the Dazzlings. Adagio Dazzle, being the leader of the group. Ever since they gave up on returning to Equestria and learned to co-exist with the people here, they wound up eventually turning over a brand new leaf and are finally good. They even became more independent with their lives, doing the things they love and it wasn't long before you eventually hooked up with Sonata.

You and Sonata became boyfriend and girlfriend some time after the Starswirl Festival and after graduating high school, you and Sonata got your own house. It's not much, but it is functional and you and Sonata couldn't be anymore happier with each other. And so right now, as everyone has left the house and the only ones left are you, Sonata... and Aria.

Turning around, you look at all the gifts each of your friends have given you and are fascinated by each individual and very unique present. "Man... today has been just about the best birthday I've ever had in all my years, I can't thank you and everyone else enough."

"I'm glad you enjoyed your special day, babe. But..." Sonata pauses and leans in, whispering into your ear, giving you the good goosebumps. "...I still have one more surprise for you, babe." Another surprise, even though the party's ended? Hmm, this should be interesting. "Now, close your eyes and whatever you do, don't open them until I tell you to, okay?" she instructs with a cute giggle.

"Okay." You close your eyes and wait for something to happen. Then, a few seconds later, you feel a pair of lips, which you assume to be Sonata's, kissing you. Not only that, but you can feel her arms wrapping around you, so you do the same.

She even adds some tongue, which you don't mind. "Open them," says Sonata. Wait... how is Sonata talking to you if you're kissing her? Shooting your eyes open, you realize it's her sister, Aria, who's making out with you and Sonata's watching with her usual cute smile, giggling. "Surprise!" she exclaims. After she reveals the surprise, Aria pulls away, big blush appearing across her soft cheeks.

"Uh... wow... that felt good, but... Sonata, what's going on here?" you ask.

"Here's the thing, babe. My gift to you is that I was hoping to share you with Aria. And the reason why I wanted to surprise you like this... is because she's also had a crush on you, before I became your girlfriend, but she never had the courage to tell you in person. She's never had a boyfriend before because guys are too scared of her "tough girl" attitude." When Sonata explains this, it leaves you shocked to think Aria felt this way towards you, but even moreso for Sonata to arrange this surprise.

"Unfortunately she's right," Aria confirms, looking away, ashamed.

"Aww, Aria... I'm sorry. I didn't know you felt that way towards me. Though, I can understand why you had trouble trying to confess to me. Come here," you open up your arms to her and approach her, giving her a big hug, which she hugs you back more tightly.

"So, does this mean you... you accept my feelings?" Aria asks.

"Well, Sonata's willing to share me, so who am I to deny your feelings?" you confirm. Aria smiles at you, happy to hear those words and now feeling like a heavy stone has lifted off her heart. Just then, Sonata jumps in and hugs you both, making one more announcement.

"And the fun's just getting started, so I hope you're ready!" Sonata says.

You're confused and are about to ask why, but just after she says that, Aria's mood changes back to her usual bad girl self with that confident smirk. "Not another word, lover boy. You'll see what we've got planned for you, so shut up and just role with it," she orders. She and Sonata both grabs your arms and pull you into the bedroom... your bedroom and that's where they lay you on the bed.

'What the...' you think to yourself, sitting up. Then, a delicious sight meets your eyes. A sight which you'll never forget in years to come.

Sonata and Aria begin to strip right before your very eyes. They twist and sway their gorgeous, sexy bodies to get you plenty excited for what's to come. Eventually, both girls are now showing off their mostly-naked bodies, with Aria wearing a black bra and panties. Sonata, on the other hand, wears a red bra and panties, but despite how cute and sexy they are... you still feel a bit skeptic about this.

"Listen, I... I get that Aria's been crushing on me for quite some time, but still... are you sure you're alright with sharing me with her? I mean, what if it messes up our relationship?" And before you can question them any further, Aria shushes you with her hand.

"Oh, just shut up and relax, you big baby," Aria grins. She gets on top of you, then grinds her fine ass on your growing boner while Sonata climbs onto the bed and sits herself right next to you. This still feels like some kind of wet dream, even though it's happening right in front of you. Your girlfriend, whom you've been crushing on is now sharing you with her tough girl sister, who's actually been crushing on you.

"S-Sonata, I--" But you're stopped when Sonata kisses you briefly.

"It's okay... just let it happen. I'm actually okay with this. I don't mind sharing you," She assures, giving that oh so adorable smile that melts your heart. After that, the sweet taco-loving cutie then cups both of your cheeks and pulls you in for a make-out session. You abandon your doubts and swap spit with your sweetheart, all while Aria takes the initiative and removes your pants and boxers. As soon as she sees your cock spring up, the tomboy then licks her lips at how delicious and big it looks.

She grabs it with one hand, stroking it with her surprisingly soft hands. She lolls out her tongue and licks your phat cock like a giant lolipop. Her wet, soft tongue on your cock makes you shudder.

Aria starts off nice and slow just to work you up and tease you. You and Sonata are still making out with each other, hearing her cute humming as your tongues dance together. You wrap one arm around her and grope one of her E-cup breasts, fondling it through her bra. Sonata moans softly in the heated kiss, deepening it, then runs one of her hands under your shirt and feels your manly chest and pecs.

It feels like a hurricane of pleasure, having your girlfriend make out and feel your manly chest while her sister jerks and licks your man sausage. Not even your dad was this lucky.

Soon, Aria takes in the entire length and sucks on it hard and fast. She even hums on it and goes so far as to deepthroat you without any troubles. Now you REALLY have the goosebumps. Aria's bed skills are out of this world, but she doesn't even stop there. Aria even goes beyond and grabs your ballsack and fondles your family jewels while bobbing her head up and down, making lewd sucking noises. Your body trembles from the sweet sensation all over and can't... or won't do anything to stop it.

Her tongue swirls around your massive dick as she continues to blow you. Sonata then stops making out with you so she can remove your shirt. She does so and checks you out.

"Mmmm, still as healthy as an ox," Sonata says after licking her lips. She then goes full-on sexy mode, licking your manly chest and dancing her fingers against your manly abdominals. You're not exactly a suped-up body-builder, but you do find the time to keep in good health. Before, you used to be a bit on the skinny side and that was during the beginning of your relationship with Sonata. But after some visits to the gym, pumping a bit of iron and a little cardio, you've turned your life around dramatically.

But enough of that. These two sisters keep working and loving your body to no end. You stroke Sonata's beautiful hair, even her cute ponytail. She stares up at you with her big, magenta eyes.

Aria proceeds to go super fast on your cock and sucks harder than before. Even fondling your ballsack some more, quickly driving you close to your first orgasm of the early evening. She gives a throaty moan while sucking on your massive dick. The pressure down below is quickly building up and you can't do anything, except twitch from this amazing pleasure. Sonata then goes so far as to suck on one of your manly pecs, swirling her tongue around your manly nipple.

These girls' combined efforts eventually push you over the edge and you thrust your hips upwards, shooting your cock into the back of Aria's throat, cumming hard.

Her cheeks inflate from how much cum is pouring into her mouth and down her throat. But she's no wimpy beginner and moreso a bold one as she gulps it all down in big gulps. You keep groaning from every few spurts, it feels so breathtaking. Sonata then removes herself from your pec and turns to her sister to see how she's doing so far with handling her very first blowjob with you.

"So, how'd you enjoy it?" she asks her.

Aria removes her mouth from your still-hardened cock, sighing in satisfaction. "Damn... that tasted so good, I even savored the taste of it," Aria replies as she removes her underwear. You watch as she stands herself up and reveals her dripping wet pussy to you. Sonata then sits herself on the edge of the bed while Aria proceeds to climb on top of you, grinning down on you seductively. "So, big boy... you ready for the main event?"

You don't say a word. Instead, you get into the mood and spank her fine ass. She moans, biting her lip while grinning, getting turned on bit it.

"I'll take that as a yes. Then, here I come," she says as she lifts herself up. She grabs your cock and then sinks down on top of it, sinking the entire thing into her warm, tight, wet pussy. "FUCK!!! Mmm, you're hella bigger than I thought you were." she comments. You spank her again, she moans again. "Mmm!!! Yes, punish me some more, daddy, I've been such a bad girl lately!" she says, getting into the mood. You do so and spank her jiggling ass repeatedly all while she begins riding on top of you.

She lets out these erotic moans. She bounces and rides you, all while taking her "punishment" and liking it like the bad girl she is. You gotta admit, the way she blushes and smiles while being punished and fucked hard makes her look very cute.

You can't stop yourself but sit up and hug her while thrusting your hips together with her and then making out with her and spanking her ass until it's rose red. While you're doing this, Sonata watches from the sidelines, masturbating to you fucking her sister. She fingers and rubs her soaking vulva, letting out cute moans as if picturing you drilling her at the same time. She also gropes one of her boobs and fondles it.

Obviously, you can hear your girlfriend pleasuring herself and glance at her direction, feeling a bit bad that she has to watch from the sidelines. Once you're done with Aria, you're gonna make sure Sonata gets equal treatment and fuck her good.

However, what you don't seem to know is that Sonata always fantasized about watching you fuck another girl... preferably one she trusts immensely and masturbating to you two. And because it's Aria, she's finally getting her wish and can enjoy her fantasy to the fullest. She blushes deeply, still having her eyes glued on you, her handsome and adorable boyfriend... and her rough-edged sister who's been crushing on you.

For the moment, Aria pulls away from your lips. "FUCK!!! I was so fucking stupid for not telling you how I felt... I should've been honest from the start!" she yells. Clearly she full of regret.

But then, you stop for a moment and kiss her, not out of lust, but love and stroke the back of her cheek with your thumb, easing her distress. "It's okay, Aria. I understand. It's never easy telling the one you love most how you feel about them. After all, the way I see it now... underneath your tough exterior, love was waiting like a shy child to speak out... but it never got its chance. Until now..." you reply with sincerity.

"You... You mean it?" Aria asks with a sad smile.

"Yeah. So let go of all your regrets and replace them all with love... and intense pleasure," you assure her before hugging her close and she hugs you back.

"I love you so much," Aria finally says.

"I love you too, Aria. You... and Sonata," you reply.

"Awww, how sweet," Sonata comments, touched.

And so, after having poured out her feelings for you, the two of you resume moving your hips in sync, jamming your cock in and out of her pussy and drilling deep inside of her. She moans loudly, holding onto you for dear life and Sonata continues to watch and masturbate from the sidelines. Her lady juices keep leaking all over the bed sheets and she moans loudly, unable to stop.

Having both of these beautiful ladies moan constantly is like a beautiful symphony. You decide to pick up the pace and thrust harder and faster, keeping one arm wrapped around Aria's waist.

Aria's mind feels like it's going blank as your cock drills her hard and fast. Her pussy being shaped to only fit your massive, manly, beefy cock. "Mmmmm, fuck! Drill me harder! Deeper! Faster! Come on, show this bad girl what you've got, daddy!" she urges as she draws closers to her climax. You're also not that far behind and even Sonata's loud moaning signals you of her upcoming orgasm.

You don't stop there. You keep going and grunt and growl like an animal. Aria's pussy tightens around your manhood and your cock grows and throbs, ready to blow like a volcano. Aria's getting turned on by your vicious, predatorial growl, liking how dominant you sound.

Sonata keeps rubbing her wet womanhood fiercely, moaning even louder. And just as she's about to reach the end, Aria beats her too it, screaming as her orgasm hits hard. This causes you to cum hard inside of her, filling her up in multiple large spurts. Sonata is the last to scream and cum all over the bed sheets, arching back from how good it felt, watching you two fuck in front of her. You twitch in pleasure, as does your cock, spurting its last bit of cum inside Aria's warm passage.

After that, Aria then collapses on top of you and begins to make out with you. This lasts for at least a minute before Aria finally rolls onto the side of the bed next to you. Both of you panting heavily and then look into each other's eyes, smiling.

"You were fantastic, Aria," you say softly, stroking her soft cheek. She winks at you before you feel Sonata climb directly on top of you and sinks your joystick directly into her love hole. Normally, anyone else would be tired from one or two rounds, but thanks to all the times you keep in shape and the many love sessions you had with Sonata in the past, you can last another round, 5 rounds maximum.

"Okay, guess who's turn it is to ride your tasty cock!" Sonata says.

After taking her position on top of you, the taco-loving airhead starts riding your dick. Her cute, round ass jiggles every time she slams them against your crotch. You thrust your hips upwards in a perfect rhythm with your girlfriend, giving her a really good time. Sonata stifles her moans, biting her lip, but just can't seem to stop smiling or blushing simultaneously. She looks so cute when she's having fun.

Just then, your attention is turned to Aria, who grabs your cheeks and pulls you in for a deep, passionate kiss, then wraps one of her arms around your upper torso. You grope one of her D-cup breasts and fondle it, getting her aroused and kissing you deeper.

Sonata starts to speed up her rhythm, as do you and your cock drills her deeper, knocking against her welcoming womb entrance repeatedly. Sonata always loves it when you hit her deepest and most sensitive parts whenever you both you're in the mood for sex. Your sweet taco girl even fondles her own boobs, getting lost in her own world of endless pleasure. Aria glances at her sister while still swapping spit with you.

Aria also keeps moaning as you treat her body with love and respect and then pulls away from your lips, dancing her hand around your manly chest.

"Look at you... scoring a 2nd girlfriend on your birthday and fucking her on the same day. You must feel like the luckiest fucking guy in your whole life," Aria says, then turns to her sister. "Hey sis... don't go bragging about this to anyone, but... thanks for giving this amazing night. For an air-headed taco-loving maniac, you're not such a bad sister after all."

"You're welcome, Aria," Sonata giggles. She keeps on riding your meaty joystick and you keep pumping it inside her love tunnel like a steam piston.

At the same time, you begin to pleasure Aria some more, groping one breast, then sucking the other on the nipple and finally... using your vacant hand to finger her pussy and rubbing it intensely, causing the tough girl to moan more erotically and tremble at your touch. She squirms and holds you close to her bosom, dancing her fingers across the locks of hair on your head. No other man has ever touched her the way you are right now and it feels so damn good to stop now.

"Fuck!!! That's it! Keep going! My pussy and boobs are yours! Work 'em like you own 'em! Don't you DARE fucking stop you handsome son of a bitch!" Aria hollers in pleasure.

Sonata's pussy continues to squeeze your massive cock and lather it with her womanly juices and soon, her inner walls get tighter, ready to cum soon. Sonata's increase in volume is a sure givaway. By this time, Aria then stops you and climbs onto you and sits on your face. At this point, her pussy had been cleaned out and now... it's officially time to go for the gusto. You thrust your tongue inside her tight quarters and slurp her lady juices, now causing her to moan as loud as her sister.

Your shaft starts growing and throbbing, building pressure and ready to explode soon. You also moan, but it's muffled by Aria's wet pussy. All three of you were reaching your limits. The pleasure's becoming so good, Aria and Sonata eventually hold hands.

"Come here you damn airhead!" Aria orders, leaning in halfway, Sonata meeting Aria and pressing her lips onto her sister's, kissing each other. You cannot believe what you're hearing. Now things are REALLY heating up, especially now that the tomboy and the cutesy airheaded taco lover are making out while they ride your cock and face and you keep enjoying your sweet and sour beverage.

And finally... altogether, the three of you shout at the top of your lungs and cum at the exact same time, shooting your liquids out. Aria's liquid honey spraying into your mouth, Sonata's love nectar spraying all over your cock and balls and finally... your meat volcano erupting and painting Sonata's womb white.

This... is by far... the BEST climax all of you have had. All of you twitch from how good the sensation hit you all and eventually, you and the two girls finally calm down.

Minutes later, you're all now laying on the bed, completely drained from the wild sex.

Aria's currently laying on your left and Sonata's on your right. The sweet cutie-pie then leans in and pecks you on the cheek and cuddles close to you. "So, babe... did you like your present?"

"Like? Oh, I loved it. I've never experienced a threesome before. You... and Aria... you both made me feel like a whole new man because of this. And for that... I thank you," you reply.

Both girls blush at your praise. Aria then cuddles up close to you. "Thanks, but we both know I was way better than Sonata ever was. I should know since I DID make you cum faster than she did," Aria says, giving Sonata a smug look, but Sonata just laughs it off.

"Please... I was just being merciful. I can make him cum in less than a minute if I tried next time, but you're welcome to try again... if I get to watch," Sonata replies confidentally.

"Uh... wait, you mean to tell me that you LIKE watching me and Aria fuck?" you ask. Sonata nods, then explains to you how watching you fuck another woman who's trustworthy and masturbating to the both of you is a huge fantasy of hers. Guess you got paranoid over nothing. Your girlfriend is certainly full of surprises... only now you have two girlfriends by your side. How lucky are you?

"Also... I'll take you up on that challenge!" Aria brings back up.

"You know... I'm actually looking forward to it in the future, too," you also agree. You then give Aria and Sonata a kiss on the lips goodnight each. "Goodnight, girls. I love you both so much."

"We love you, too," Aria and Sonata reply simultaneously. Afterwards, Sonata gets out of bed and goes to turn off the lights in the whole house before returning to bed.

She and Aria snuggle up to you and sleep soundly into the night. As you fade out of consciousness, you can't help but feel so happy as to how this birthday turned out for you. Good friends, lots of fun games, simple hang-outs... and in the end... a fun-filled relationship with two of the most beautiful girls in your life. This has been, by far, the best birthday ever.
