It was a cold snowy day in Ponyville and everyone was all ready for Hearth's Warming. In one of the house we see two brothers in there. One was a dragon with yellow skin, red spiky hair with black streaks, orange eyes. The other was purple with green scales. They were Inferno and Spike. Now Spike was packing up for a trip and Inferno was curious. And both of them were 19 years old.

"Hey Spike-O? Where you heading off to?" Inferno asked.

"Well my girlfriend Rarity invited me to stay with her for Hearth's Warming so im going to spend the Eve with her." Spike answered.

"That's nice. And Spike I hope you ain't mad at me but I invited my girlfriend Sunset to stay here with me while you were gone. Hope it was okay." Inferno replied.

"Oh it's no problem. You and Sunset are dating so I don't see any problem with it." Spike told him.

"Oh thank goodness. Well I hope you have a good time there. And if you need anything just gimme a call." Inferno replied.

"I will. I'll see you on Hearth's Warming Day." Spike said as he headed out for Rarity's place as Inferno smiled.

A few hours went by and night time came in and Inferno was reading a book about his favourite hero. Suddenly he heard a knock on the door and he got up to answer it. To his surprise he saw his girlfriend smiling at him. She was a anthro pony with marigold skin, red hair with yellow streaks, and aquamarine eyes. She was Sunset Shimmer.

"Hey there's my little Sunny." Inferno said.

"And there's my handsome blazing dragon." Sunset replied as he let her in and shared a kiss.

The two walked into the living room and sat on the couch cuddling each other.

"So Sunny. What's been going on? I haven't seen you in a while since you decided to stay in Equestria." Inferno asked.

"I've been busy helping Twilight preparing for the Hearth's Warming Party that will happen in a few weeks. But im glad that I got this time off to spend with you sweetie." Sunset answered.

"Me too. I just hope that Twilight doesn't go into freakout mode when something isn't right like last year." Inferno worried.

"I assured her that this year's party will be okay. She wouldn't freakout again. But enough about me. What have you been doing honeybuns?" Sunset asked.

"Oh nothing much. Just helping out my brother and all that. But in all honesty I was hoping to see you again for some fun anytime soon." Inferno answered.

"Aww. You big ole softie. That's sweet that you were thinking about me. And if it doesn't embarrass you were also thinking about my.....booty?" Sunset purred.

"Oh yeah. Millions of times. Your ass is like a pair of jumbo marshmallows." Inferno replied.

"Well then..if that's the case then shall we have some fun tonight?" Sunset offered.

"Oh you naughty girl. Of course I like to have some fun tonight. My room?" Inferno asked.

"Yes. Lets." Sunset said as the two headed to his bedroom. In there Sunset changed into a hot sexy santa outfit that showed off her breasts and butt real good. Inferno couldn't contain it and felt dizzy.

"Ok what am I looking at? Is has gotta be a dream." He replied.

"It's not a dream dear. This is really happening. Now come here and kiss me you fool." Sunset begged.

"Oh you come here!!" Inferno replied.

He needed no more encouragement as the both of them puckered lips and leaned in til they touched. That started their makeout session as both tougues were exploring each other's mouths battling for dominance. He took one hand and rubbed her back while the other was squeezing her butt. She moaned in the kiss loving that treatment. It lasted for 10 minutes til they separated and looked into each other's eyes.

"Mmm. That was a wonderful kiss." Sunset replied.

"It sure was. Now lemme see what you're packing in your chest." Inferno said.

"Your wish is my command master." Sunset purred.

She took her top off releasing her massive E-cup breasts and Inferno couldn't take it. So he stuffed his face in her bosom and started to suck and kiss her right tit while massaging her left one. This made Sunset coo, moan and purr like a cat. Inferno went back and forth on her tits making sure they both got equal attention. This lasted for 10 minutes til he stopped and looked at Sunset's blushing face. Then she had an idea. She took her breasts and squished them between his cock and starting titfucking him. He moaned in pleasure from her tits and she starting giving him a blowjob. Inferno loved this even more and moaned louder than ever. This lasted for 20 minutes til he blew his load into her mouth and licked up all the juices.

"Mmm. That was good. So did you enjoy that?" Sunset asked.

"Most definitely dear. And I loved playing with your boobs." Inferno answered.

"Then could you rest your head on my boobs? I want to know how soft you think they feel." Sunset said blushing.

Inferno gave her the answer she needed and placed his head on her breasts. He loved how soft they were and was about to fall into a deep sleep til Sunset tapped his shoulder which made him look at her.

"How did you enjoy my chest pillows?" Sunset wondered.

"They were so soft and so cozy. I almost didn't want to leave them." Inferno answered.

"Glad you think so and....." Sunset said but heard her belly rumbled. That caused her to grow into a giantess and Inferno was now a little scared but confused and turned on at the same time. When she stopped growing all her clothes were in pieces and was naked.

"Oh dear. I was hoping that wouldn't happen." Sunset worried.

"What happened to you Sunny?" Inferno asked.

"If you must know back in the human world Twilight had me try a potion that makes anyone grow giant and become real horny. At first I thought she was joking when she did that. But I now see that she isn't." Sunset explained.

"Well how am I supposed to squeeze your butt if your a giantess? There's gotta be a way to shrink you back to normal." Inferno said.

"There is one way. You need to pleasure my giant body well enough to shrink me back to normal. According to Sci Twi she says it's the only way to reverse the affects of the potion." Sunset offered.

"If it's the only way to reverse the affects then I shall do it. Where do I start?" Inferno asked as Sunset picked him up in her hand.

"Start with my boobs. I know you can't resist them." Sunset answered.

"Okay. Here goes nothing." Inferno said as he jumped straight into her boobs as she moaned.

Then his inner perv awakens now as he went to her tits and tried to squeeze them together with a little help from Sunset, he was pressing his face in between them as he enjoys the softness and the warmth. Pulling away, he let go of the right tit and grab the left with both hands. Bringing the nipple to his mouth, he wrap his lips around it and gave a suckle on it.

Hearing his girlfriend moan cutely above him, he squeeze the mound and knead it with both hands. Gently biting the nipple, pull back to let it snap back, making the breast ripple slightly. Using his left hand, you pull the right breast closer to your face as he begin to suckle on the right nipple. After 30 minutes of sucking her tit she began to shrink a little. But still had to keep pleasing her.

"It's working! Try pleasing my pussy next." Sunset purred.

"Alright. Let's see if I can pleasure a giantess's pussy at this size." Inferno said as he went to her giant dripping flower.

Once there he shoved his face into her pussy and started licking away. Sunset moaned as loud she could but was lucky that no one else heard her.

"Man. This is some next level shit dude." Inferno replied and continued going all over her giant pussy and licking like crazy.

Then after 20 minutes she sprayed her cum all over his face. He licked up all the juices and stared at her face. He also noticed her shrinking a little more after that.

"How was that my love?" Inferno asked.

"Great. But im still too big for you to squeeze my butt. Can you think of anything else to pleasure me?" Sunset wondered.

"Maybe a footsie? Where I can rub your bare feet? Lemme try that." Inferno replied.

He went to one of her giant feet and on the left foot he began using his hand to rub it. After 5 minutes he got an idea. He climbed on loot and reached the toes. Then he started licking her giant toes as she moaned for that. Afterwards he got off and repeated the process on the other foot. Then after 40 minutes Sunset's feet were all pleased and she shrank a little more.

"You're footsie idea worked perfectly. But im still too big. Keep going. In fact lemme lay on my belly and let you explore there." Sunset replied as she laid on her stomach.

Inferno went climbing on her backside and went on her giant ass. He noticed that he wanted to squeeze those cheeks but can't right now. So he thought maybe he try something else. He then wondered if her ass was bouncy to jump on. He jumped and turns out it was bouncy. So he kept on jumping and having fun on her ass as Sunset smiled see him do that.

"Jumping on my ass now are you? Well this is making me smile so I will leave him to it." Sunset thought to herself.

After 20 minutes of jumping. He stopped and landed on her back and slipped. Then she shrank a little more and was almost at normal size.

"Your almost there! Just do something on my back and I will be back to normal." Sunset said.

He nodded and tried to figure out what he can do on her back. But everytime he tried standing up he slipped. He then noticed that Sunset moaned from that. So he decided to skate on Sunset's back and sometimes use his hands for extra pleasure. that made her moan even more. Then after 50 minutes Sunset felt so relaxed and shrank down back to normal. Inferno smiled seeing his girlfriend at normal size again.

"You're back to normal! Come here sweetums!!" Inferno said opening up his arms.

Sunset came to him and the both hugged and kissed.

"So now that I returned to normal..... wanna pleasure my booty now?" Sunset purred.

"Oh you don't have to tell me twice. Lemme see that tight ass." Inferno replied.

She stand up and Inferno laid back down and saw her massive butt above his face. Then she slowly brought her rear down and covered his face in her butt.

"Ok babe. Be a dear and pleasure my butt." Sunset purred.

Inferno gave her butt a tight squeeze and started playing with her cheeks. He also licked the crack tickling her as she moaned a little. Inferno then picked up the pace and licked faster and squeezed more often on her butt. She loved it when her boyfriend is doing this. That lasted for 30 minutes til she sprayed more cum on his face and he licked up every last drop. She got off his face and laid next to him.

"Oh Inferno. That was a wonderful massage. My butt feels much better. You should be a masseuse." Sunset offered.

"Maybe I will someday. Now let's end the night by fucking each other's brains out." Inferno offered.

"I like that idea. And don't worry. I took a pill so you won't get me pregnant. Now get over here and fuck my ass." Sunset begged.

She got on Inferno's cock and began riding him cowgirl style. He panted and moaned from that and he grabbed Sunset's chest and started to squeeze her pillows making her moan since he didn't want her doing all the work. That lasted for an hour til he blew another load everywhere and she licked up the juices. Then they switched positions and Inferno grabbed her butt and stuffed his cock into her ass which popped her cherry. She cried a little but he rubbed her back calming her down. Then he started fucking her nice and slow as she moaned softly. Then Sunset begged Inferno to pick up the pace and he started going faster. Then he ravaged her like an animal as she moaned and yelled so loud with each and every thrust she took. Finally after 2 hours he blew a final load into her butt as she screamed in pleasure. Then he took his cock out of her and they both laid down all sweaty and panting while cuddling. Then Inferno did one final thing for Sunset. Worshiping her body. He rubbed his hands on her hips, legs, breasts, back and butt for 2 hours til she stopped and kissed her again. After that they stared into their eyes.

"Oh Inferno. That was lovely. Thank you for showing how much you love me." Sunset thanked.

"Your welcome. Im your boyfriend for a reason. Im suppose to love on you. That is a way of me saying that I care for you." Inferno explained.

"Yes sweetcheeks. But you really tired me out. Let's rest for the night." Sunset offered.

"Yeah I could use a rest myself." Inferno replied as he turned off the lights and cuddled with Sunset.

"Goodnight honey." Sunset said.

"Goodnight sweetums." Inferno said back.

And so the two drifted off to sleep and dreamed of what holds in their relationship. But they know nothing is going to break their love for each other.
