11:00 PM... an hour and thirty minutes after Button Mash's 18th birthday party concluded with the dirtiest foursome featuring his best friend and his two favorite girls, his girlfriend Sweetie Belle and his mom Cream Heart. The two girls were so exhausted from the out-of-control orgy that they passed out on the floor of the shower. They both let out a big yawn as they wake up from their sexually induced slumber. They find themselves on the shower floor both draped in bath towels and sitting next to folded up towels that served as pillows.

"W-what happened?" Sweetie Belle asks rubbing her tired eyes.

"Mmmgh... well we hosted a sexy birthday party for Button Mash that I think ended with the two of us getting pounded by studs with 14-inch logs of meaty goodness." Cream Heart replies, barely able to comprehend the last ten minutes of their slutty celebration. It's all a blur for her and Sweetie at this point, all they could remember from the last ten minutes was them turning into bimbos for burley men with exaggerated features. They knew it would come back to them as soon they fully regained consciousness, but for now they wanted to go to bed and dream of more cute boys. Sweetie Belle and Cream Heart get up off of the floor feeling bloated from the cum Button Mash and Rumble shot up their asses when Cream Heart realizes something. "Hey Sweetie, did you intend to spend the night here?"

"Yeah, I told Rarity that I would probably not be home tonight in case I actually slept with Button Mash. Of course I didn't think your plan involved fucking in the shower after me and Button lost our virgin status." Sweetie responds,

Cream Heart chuckles, "Sorry about that."

"Please, no need to apologize." Sweetie Belle reassures, "I loved it to bits. It served as a great addition to our original endeavors."

"I'm glad you loved it as much as I did." Cream Heart says, "Could you check to see if Button went to bed yet?"

"Sure thing!" Sweetie Belle replies, she
slowly walks out into the hallway, her hips sore from the all of the sex she had. She sees that the door to Button Mash's bedroom is closed and the lights are off, a definite sign that he had gone to bed coupled with the fact that it was eleven o'clock at night. She walks back to the bathroom where Cream Heart is putting back the towels that were folded up. "He's out," Sweetie says.

"Hmm..." Cream Heart thinks for a moment before something clicks in Sweetie Belle's head.

"Oh no, my bag is in his bedroom..." Sweetie says putting her hand up to her forehead, "...the bag that I used to switch into by swim bikini." If she didn't end up drifting off on Button Mash's bed, she would've been prepared to change back into her normal clothes and leave. But since she instead drifted off on the floor of the bathroom her bag was out of her reach, and she didn't want to disturb her boyfriend as he slept.

"It's okay Sweetie..." Cream Heart says, "...you can get it tomorrow when he wakes up." Sweetie Belle was confused, until Cream Heart pitched an idea to her. "I have a plan..." Cream says giving Sweetie Belle a sensual glare.

"You want us to take advantage of the fact I'll be here tomorrow?" Sweetie Belle asks, "How so?" Cream Heart and Button Mash have a pool in their backyard and Sweetie Belle had presented herself to Button Mash wearing a two-piece swimsuit tonight. Cream Heart figured that since Sweetie Belle would have the proper attire, and the fact that if she were to wake Button Mash up while she was naked they'd probably end up having some morning action, that they may as well have some fun by the pool. After all, Cream knew that her son would love to see both of his favorite women in the world in skimpy swimwear, and maybe even rub sunblock on their large assets too. Cream Heart explains her plan to Sweetie Belle as they get ready for bed.

"mmm, I like it" Sweetie Belle purrs. Cream Heart puts on a red nightgown that hugs her curves while also letting them breathe. Sweetie decides that she's just gonna sleep in Cream's bed naked tonight, as Cream Heart's sleepwear is too big for her.

"Tomorrow will be fun" Cream Heart says as she gets herself tucked into her queen-sized bed next to Sweetie Belle.

"This bed seems like the perfect size for sex Cream Heart," Sweetie Belle says.

"Yeah, I have used this bed for my sexual encounters..." says Cream Heart, "...and now maybe someday I can get my hunk of a son in here."

"And maybe you should borrow one of my nightgowns to wear for him, though they may not be the right size" Sweetie replies with a chuckle.

"Hey, it's not my fault that my features are as big as they are," Cream Heart chuckles, "though I'm kind of surprised that my sleepwear was too big for you considering our figures are pretty similar." Sweetie Belle blushes from Cream's compliment.

"You mean we're similarly sexy?" Sweetie Belle asks with a seductive look on her face.

"Well Button Mash loves both of us doesn't he?" Cream Heart playfully asks,

"Yeah..." Sweetie says putting her hand on Cream Heart's left boob. Cream Heart puts her hand on Sweetie Belle's gorgeous booty in response. "You're such a naughty girl..." Sweetie Belle purrs as she plants a kiss on Cream Heart's lips before resting her head on her shoulder. Cream Heart plants a kiss on Sweetie's forehead in response.

"Goodnight precious..." Cream Heart says before the both of them fall asleep in each other's arms.

It's 11:00 AM the next morning and the two girls wake up to get ready for their post-birthday fun with Button Mash. Cream Heart goes out into the hallway and sees that Button Mash is up. She goes out into the kitchen in her nightgown and sees that breakfast is on the counter and Button Mash is putting away dishes, presumably having already eaten.

"Good Morning son," Cream Heart says

"Good Morning Mom," Button Mash replies,

"You made breakfast for me and Sweetie Belle?" Cream asks as she makes eye contact with two plates of pancakes coupled with eggs and bacon on the side.

"Yeah, I figured after you two threw me the best 18th birthday party ever last night that, well I wanted to pay you both back," Button Mash responds. Cream Heart gets a fluttering feeling in her chest. The fact that her son was willing to slave away this morning preparing this meal for her and Sweetie Belle made her feel so loved and cared about. She walks up to Button and gives him a big kiss on the cheek, her breasts slightly rubbing against his shoulder as she did so.

"Thank you so much for that, you're so thoughtful," Cream Heart swoons, making her son chuckle a bit.

"I hope you like it, the eggs and bacon might be a bit lukewarm," says Button.

"It's fine," Cream says, "I'm sure Sweetie Belle will enjoy too."

"Speaking of which, where is she?" Button asks.

"She's getting changed into her swimsuit," Cream Heart replies, "we're gonna be going out to the pool today...would you like to join us Button?"

"Why of course," Button Mash responds. He wasn't going to turn down the opportunity to swim with his two favorite girls in equestria.

"Great! Me and Sweetie will be out as soon as we're done eating," Cream Heart says. Sweetie Belle finishes changing into her swimsuit and goes back into Cream's room for a brief moment. Button Mash finishes with the dishes and goes into his bedroom to change into his orange swim trunks. Sweetie Belle sees this as an opening for sneaking into the kitchen and joining Cream Heart for breakfast. Meanwhile, Button Mash goes out back to where the pool was. The area had a patio with two chairs, an umbrella, and a table set up by the pool. There was one section that had a bathtub that Cream Heart would use frequently in the evening if she felt like she needed relaxation. And then of course there was the pool itself. It was an 18x6 rectangle and the deep end was about 9 feet deep. It looked very inviting, especially considering the weather, and Button Mash was looking forward to having some fun in the sun with two people he enjoys having around.

Button Mash, wearing nothing but his swimming trunks and a pair of sunglasses, takes a tube of sunblock and pours some onto his hands before beginning to rub himself down. The feeling of the lotion was cooling for Button Mash's skin that was exposed to the heat of the summer sun. After he finishes applying the sunblock onto himself he decides to let it sit for a moment while he was on dry land as to not accidentally wash it all off. He takes his phone and puts on some beach wave ambience as he lays down on one of the chairs letting the sun give him a little tan. Another 10 minutes pass and Button Mash feels himself starting to drift off from the serenity of the ambience. That is, until he hears the sliding door open behind him and a familiar voice call his name.

"Oh Mashie-pie!" Sweetie Belle calls. This gets Button Mash's attention as he rolls over to see Sweetie Belle in the same swim attire she wore the previous night as well as his mom in her own special swimwear. Cream Heart wore a metallic fuschia colored G-string micro-bikini with a top that left most of her boob flesh exposed and a thong that left her bottom bouncing freely as Cream walked over to her son with Sweetie Belle. The two girls are carrying glasses of ice cold lemonade in their hands, Sweetie Belle was carrying two saving one for Button. Sweetie sits herself down on the chair next to her boyfriend and places both drinks on the table. "How's my favorite fella?" Sweetie Belle asks while taking a sip of her lemonade.

"Doing pretty well, thanks for the lemonade, " Button Mash replies. Sweetie Belle grabs the sunblock and begins rubbing it on herself. Meanwhile, Button Mash grabs his lemonade and notices his mom setting her drink on the table before setting up a third chair next to him. Cream Heart bends over a couple of times to try and set up the chair, giving Button an enticing view of her moneymaker. His attention is broken however, when Sweetie is done applying sunblock on her frontal area and makes a proposition to him.

"Button darling, would you mind helping me apply some sunblock on my back?" Sweetie Belle asks with a purr in her voice.

"Of course babe," Button Mash responds. Sweetie turns over on her chair and Button begins the application. He squeezes some sunblock on his hands and gets to rubbing it on his sexy girlfriend's smooth and firm back. Button Mash decides to give Sweetie a little massage as she lays there moaning and relaxed from the sensation. He interrupts his back massage to move on to rubbing sunblock on his girlfriend's sizable ass. He squeezes some more of the lotion onto his hands and places both of them on Sweetie Belle's bikini-dawned rear.

"mmm~, good boy... <3" Sweetie Belle moans. Button Mash continues rubbing his girlfriend's ass and legs as Cream Heart grabs the sunblock and applies some onto her hands. She rubs some on her son's back making him grunt in pleasure as he finishes on his girlfriend's body. Sweetie Belle's soft and smooth skin now had a little glimmer in the sunlight that made her half-naked body look even more enticing.

"Now that I'm done with your back son," Cream Heart says, "how about you apply some sunblock..." Cream Heart moves up to Button Mash's ear and whispers "...all over my body?" Button gets a chill up his spine upon hearing his mom talk so seductively and his trunks couldn't get any tighter. He nods his head in response, takes the tube of sunblock, and Cream Heart stands in front of him ready for herself to be touched like no other man has touched her before. She gives her voluptuous titties a little shake as Button Mash squeezes some sunblock onto his hands and begins the application. He rubs his mom's massive mammaries with his lotioned up hands and gets a feel for the combination of textures. The cool and creamy lotion being rubbed into Cream Heart's soft and squishy breasts made her moan in pleasure. Button Mash finishes applying the sunblock onto his mom's fuckable fun-bags and although he would be happy just massaging her tits for the entire day, Cream Heart has other plans. "I think Sweetie Belle can get the rest of me honey, I'm sure you would love to rub some lotion on my fat ass-cheeks wouldn't you?" Cream Heart purrs. Speaking of Sweetie Belle, she was sitting on the patio chair completely naked and pleasuring herself as she watched his boyfriend's manly hands explore Cream's huge mammaries.

"Oh yeah baby," Sweetie says while directing a devious look at Cream Heart. Cream walks over to Sweetie's chair and Sweetie stands up so that she and Cream are inches away from each other looking as if they could kiss at any moment. Button Mash hands off the sunblock to Sweetie Belle, who applies some extra sunblock onto Cream Heart's supple breasts and onto her own hands before handing the tube back to him. Sweetie Belle rubs her lotioned hands onto Cream's belly, arms, and legs as Button Mash gets her back. He eventually makes it to his mom's thong clad ass and Sweetie undoes Cream's tiny top that did nothing more than to cover her hard nipples before giving her mounds a naughty rub. Cream Heart moans from the feeling of her assets getting kneaded like dough, it made her want to also get pounded like dough, her juices made her thong look like she had just had a swim.

"Someone's a naughty girl today," Cream Heart moans.

"Did you think I was gonna forget our pillow talk last night?" Sweetie Belle purrs, "You think I'm sexy."

"Nnn~ yeah, you're perfect for my son," Cream Heart responds, "oh... You two make such a cute couple." Button Mash takes the liberty to remove his mom's thong exposing her dripping pussy to Sweetie Belle. Sweetie lays back down on her chair ready for her and Cream to have a little passionate make-out session.

"Go on girl," Sweetie says seductively, "show me how much I turn you on. More importantly, let's show our man." Cream Heart doesn't even hesitate to crawl on top of Sweetie Belle and plant her lips on the girl that was banging her son. The two girls wrapped their arms and legs around each other and moaned into each others mouths like the horny sluts they were. They knew that Button Mash had a fetish for watching two naked oiled up bimbos perform girl on girl action on each other, and they wanted to show Button Mash that they were his lesbian sluts.

Cream Heart shakes her massive ass, inviting her son to do literally anything he wanted with it. Button Mash takes off his swim trunks, letting his itching member fly free, before placing his dick in-between his mom's ample rump cheeks. He pours some sunblock all over his meat and his mom's buns and gets to work humping like a dog. His dick was squeezed in-between Cream Heart's beach ball sized ass-cheeks as he laid down some on his mom's back. Meanwhile Cream Heart and Sweetie Belle were enjoying the arousal they were feeling. Their loving tongues dancing around in each other's mouths, fucking each other's needy pussies as the man they loved enjoyed his ass-fuck. The sounds of the love the three of them were making echoed all throughout the backyard and they felt like they could blow within seconds.

"oh.. son~ would you like for us to be on top?" Cream Heart asks with a moan. Button Mash agrees and lays himself down on the chair next to the two girls who get ready for more action. Only this time, Sweetie Belle is the one to give her boyfriend a steamy assjob.

"Yeah, babe. How do you like this fat ass?" Sweetie purrs as Cream Heart and her continue making out in front of Button Mash. The two girls' plush sets of fun-sized boobies were rubbing up against one another, creating a pleasuring sensation for the two oiled up sluts. Button Mash meanwhile adored the sight that was in front of him. His girlfriend's thick and juicy rump grinding against his throbbing cock got him closer and closer to bursting.

"Oh yeah, you girls are so fucking sexy, Nnn~" Button Mash moans.

"Nnyaah <3, come on boy, cum for us" Sweetie Belle moans. They continue until Button Mash shoots his spunk everywhere on himself and even some on Sweetie's ass. The two girls moan in unison as they reach their wet orgasms. Sweetie Belle looks back at her boyfriend and smacks her own booty, making it jiggle on impact. The two girls decide to do something else very special for their hunk of a stallion.

"Mmm~ look at the delicious looking mess," Cream Heart says while looking down at her son's hard semen-covered log.

"I got a couple of sponges that can help clean that up." Sweetie says putting her hands on her jugs, giving them a little shake. She kneels down in front of Button Mash's sizable member a gives it a good lick before wrapping her soft titties around it. She uses her hands to squeeze and slide her tits up and down Button Mash's thick cock. The feeling of his girlfriend's big and soft melons hugging and loving his erect man-log makes Button Mash bite his bottom lip in order to stifle a loud moan from alerting the neighbors. After a couple of minutes of this orgasmic sight, Button Mash's view is obstructed by a couple of big balls of booty hovering above him. Cream Heart sits her phat ass down on Button Mash's face and begins grinding and twerking it for her son to enjoy.

"Mmfohmmfnnaah~" Button Mash moans incoherently. Sweetie Belle starts kissing and sucking on his member, making her mouth mold into the shape of a trumpet. Sweetie's tongue moving all around Button's tip plus Cream's honking caboose depriving him of precious oxygen is enough to make him roll his eyes to the back of his head unable to think straight.

"Oh yeah, you like mommy's ass in your face?" Cream Heart moans. Button Mash could only respond through his moans of pleasure. He loved the feeling of girlfriend's plush set of honkers fucking his meat and the experience of getting a face full of his own mom's booty. These two girls were horny for him, and Button Mash was just as horny for them.

"Hey Cream, you gotta try this. He loves it!" Sweetie Belle says. She noticed just how much Button Mash was twitching in between her tits and she wanted to see how he'd react to his member getting lost in a bigger pair. Cream Heart walks over to her son's swelled up dick and kneels down in front of it before trapping it in her cleavage. Button Mash can't help but thrust his hips in unison with his mom's titty-fuck.

"Oh mom, fuck~ nnn your tits are amazing!" Button Mash exclaims. Cream Heart was admittedly surprised hearing her son say something so vulgar and dirty. But she couldn't help but get even more aroused by her son's exclamation of pleasure. She removes her hands and gives her chest a good shake while her voluptuous fuck-pillows were still encasing the erect cock. Sweetie Belle creeps up behind Cream Heart and grabs her titties from behind before continuing the titty-fucking. She gives Button Mash a sultry gaze as she uses Cream Heart's supple breasts as his dick massager. Cream Heart moans as her breasts get played with by her son's girlfriend. She could feel her son's 18-year old cock twitch and leak pre onto her melons.

"If you think this is sexy, you haven't seen anything yet handsome." Sweetie Belle purrs. She lets go of Cream Heart's
plump marshmallows and moves to kneel down on Button Mash's left while Cream Heart settles herself on his right. The two girls get ready for a double-titfuck that will make Button Mash lose his mind. They squeeze their humongous jugs up against Button's throbbing hard member, the feeling of each other's titties sending wave after wave of pleasure up their spines and down to their dripping wet pussies. They use their hands to fuck Button's dick with their pillowy boobs for a good while before they place their hands on each other's shoulders and lean in for a kiss. They wrap their arms around each other to make sure that their tits are squeezed tight around Button Mash's cock. They pull each other into their kiss as hard as they can to ensure that Button Mash can feel his dick getting massaged by their fun-bags. They switch between this and using their hands as they continue to either make out, suck on Button's tip, or both at the same time. Button Mash's wildest fantasies were coming true, and he could feel himself losing control.

"Keep going girls, ooh~ I'm gonna blow a fat fucking load on ya!" Button Mash moans.

"YES! Cum on these fat boobies! Aah <3" Cream Heart moans, gasping for air after her and Sweetie Belle's passionate kissing. Button Mash throws his head back and arches his back as he spurts load after load of hot semen onto the two sets of slutty tits. Button Mash comes down from his hard orgasm to see his mom and his girlfriend covered from hair to breasts in his juices. The two girls stand back up and collect themselves after such an explosive orgasm. Button Mash softens up a bit, at least until he notices Sweetie Belle and Cream Heart licking his cum of of their tits. The two of them stared right at Button Mash as they did this, hoping the sight would spring him back up downstairs.

"That was a fat one wasn't it Cream?" Sweetie asks,

"Oh yeah, I wonder how much he has left?" Cream Heart replies.

"Depends on what other fetishes he has," Sweetie Belle says. Button Mash isn't sure what they could possibly do to make him cum a third time. He was getting a little winded and he hasn't even gone swimming yet. "How about you stand up for us honey?" Sweetie Belle asks, Button Mash complies and is standing in front of the two girls who suddenly kneel down in front of his member. "We appreciate you making breakfast for us, but if you don't mind...we're still a little hungry." Sweetie says as she licks her lips at Button.

"Perhaps you would like to fill us up yourself?" Cream Heart says sticking her tongue out, "whose throat do you want first?" After his mom said that Button Mash knew exactly what they wanted. He was gonna fuck their faces.

"Damn, you girls have thought of everything," Button Mash says. It's true, he had a fetish for face-fucking. And he was going to make sure these two bimbos opened their mouths for him. He grabs Sweetie Belle's head first and places his dick on her tongue. She responds by closing her mouth some to get herself prepped for what was to come, both figuratively and literally. Button starts off slow and short, making sure he didn't go too far back as he went slowly. But his slow speed was short-lived as he starts fucking Sweetie Belle's head like it was her pussy. Cream Heart continues to clean the spunk that was on her face as Button Mash makes his girlfriend look and feel like a mindless slut. The sound of Sweetie's gulps and the look on her face makes Button Mash go crazy with pleasure. He eventually pulls out to let his girlfriend breathe and switches to his horny mother. Cream Heart laps her son's cock with her tongue before Button grabs her by the head and does the same thing with her. Button Mash watches his mom's eyes roll to the back of her head, her eyelids twitching as if she was about to pass out, as he almost literally fucks her brains out.

"Be careful, he loves almost making us faint," Sweetie Belle warns. Cream Heart however, couldn't care less if she blacked out from this. She almost wished he'd fuck her while she was asleep. But she knew her son was too much of a gentleman to take advantage of her like that. Even though she and Sweetie Belle were letting him take full advantage of them, it was all consensual. Button Mash slips himself out of his mom's mouth to let her catch her breath before moving back over to Sweetie Belle. He continues to ram his cock down their throats making the two girls moan and giving them dumb expressions as their minds melt from the sensation. They came close to passing out at a couple of points but are able to keep their composure thanks to the fact that Button Mash would let them breathe. Eventually Button Mash loses his edge and the two girls lean their faces into each other and stick out their tongues as he cums into both of their mouths. Button Mash goes to take a swig of his lemonade to hopefully replenish his energy. The three of them are covered in sweat and semen.

"Woo! That was fun, wasn't it guys?" Cream Heart asks.

"I think so," Sweetie Belle replies, "What did you think Button Mash?"

"That was definitely an experience!" Button Mash responds, "thank you guys for that."

"No problem," Sweetie Belle says.

"And if you want to do anything else with us, don't hesitate to ask." Cream Heart says.

"Well right now, I can only think of one other thing," Button says.

"What's that darling?" Cream Heart asks.

"SKINNY DIPPIIIIING!" Button Mash yells as he runs over to the pool and dives in. The two girls watch in amusement as Button Mash swims naked in the pool. They look at each other and then down at themselves, their mounds still covered in cum. That's when they decide to join Button Mash in the pool to clean themselves up with a little swim.

"WOOHOOO!" They jump in, happy that their 18th birthday party and after-party for Button Mash was a complete success.
