Vacation drain

“Mmh, does it matter?” The young mare answers with a playful smile, and silences further questions with a kiss. Her front hooves on your chest, the mare in swimsuit can comfortably reach your lips by rearing in front of you, something that’s a bit of a novelty.

 

These ponies sure were little after all, or so you’ve been telling yourself since you arrived in Equestria. With most mares being only a bit short of 4 feet of height, you’ve been having more than a head over the crowds when you started to walk among them. Being on the smaller side, your marefriend, Silk Spark, could not get eye level with you so easily as far as you remember.

 

You and the little unicorn live in Manehattan, but are currently enjoying some vacation in Las Pegasus. Before leaving, Silk Spark showed you a pendant of some sort.

“I’m finally gonna achieve my dream look with this! Just you watch!” You remember her boast. At this moment, you merely found the piece of jewelry quite pretty, but didn’t think much of it. But now that she’s been wearing it while you were swimming in the hotel pool all morning, you’ve come to notice some really unexpected changes in Silk Spark.

 

Namely, her body felt larger when you hugged her, and coming out of the water, she definitely was taller than before. Now she stood even, if not a couple inches taller than most mares. Seeing that she seemed obviously both aware and delighted of the situation, you thus dragged your marefriend to a quiet spot to get some explanation, but she didn’t seem like she was in the mood to comply.

 

“Really, is there any problem here?” Silk Spark says after letting go of your mouth. “You know it always bothers me when ponies mistake me for a filly. And I bet you’re going to enjoy it when there’s more of me to love.”

“But… I don’t think that’s exactly a normal thing to happen, right? Can you tell me how it works? Is it permanent?”

“Oh, you better believe I’m not shrinking down now.” Silk Spark grins.

“Come on! I’m just worried, Spark! Are you even sure that what you’re doing is safe?”

“It. Is.” She says, looking straight in your eyes. “And like I said, stop worrying. How about you look at the other advantages of this.”

 

There, with her eyes still locked with yours, the mare directs your hand to her crotch, and you’re surprised to find two pliable mounds there. You’ve been suckling on her little nipples during private times, but she was always quite flat. But now, there’s was definitely some volume here you could smush your face onto.

“Woah…” You feel the red come to your face, and can’t refrain a dumb smile to appear on your face. This seems to satisfy Silk Spark.

“So, are you ready to trust me and just enjoy the ride?”

“Well… I sure don’t feel like trying to argue right now…”

“Attaboy!” Silk Spark shows you a victorious grin before rewarding you with another passionate make out session.

 

The next days were surreal. Every time you looked away from her, you’d find out Silk Spark a little taller, or with more curves, or both, and always very happy about it. You’ve been enjoying the evolution too, your hands meeting more plot to play with every night, and her teat filling your hands more each time before overflowing them entirely to the point you could motorboat them. Bigger all over, she was now also strong enough to keep you and your face wherever she pleased. Needless to say, with the choices she made, you had no complains about her direction.

By the end of your vacation week in the resort, Silk Spark was taller than you on all four. During the night she could lift you against the wall to suck you off, something that you used to do with her instead. Hands against the ceiling, you loudly cried in bliss under the powerful suction of her mouth and the ministration of her expert tongue.

“Is that okay?” You later asked between two pants, while you were embracing each other under the covers. “I don’t think I can lift you like that anymore.”

“Mmmh… That’s fair.” Silk Spark nods, resting her big head against your chest. “A small price to pay for the rest. I’ll find new ways for you to please me soon enough.”

 

The last day of your stay, after another steamy night, you woke up at somepony knocking on the door with insistence. After pushing away the large amount of mare that was still hugging you and taking a towel to cover yourself, you go open the door.

 

“Hello Sir.” A colt from the hotel staff politely bows. “I’m deeply sorry, but there’s seem to have been a magic phenomenon of some sort in the hotel. Have you or anypony you know experienced some, ehm, loss of height…?”

“Huh?”

“We’ve found out that nearly thirty of your customers inexplicably shrank by a couple inches these last days.” The worker pony explains. “We suspect some magic that went wrong is involved. Do you know anything.”

Reflexively, you turn toward the bed where your marefriend who’s big enough to occupy the whole space of the mattress lies. She avoids your glance with a mischievously look on her face.

“Ehm… We’re… We’re alright.” You blurt out to the staff pony. “I don’t think anypony shrank, here.”

The colt leaves soon after, and then you turn toward your mare friend.

 

“Silk Spark!” You call your marefriend, appalled.

“Whaaat?” She pouts. “They’ll deal with being a little shorter. I’ve dealt with worst and I survived.”

“So it IS you! You stole height from other ponies! You did it with your necklace, right?”

“What if I did?” She scrunches further, looking at you defiantly. “You want me to stop?”

“Of course not!” You retort. “I don’t want them to catch you! You’re gonna need to be more careful if you want to grow bigger.”

 

Silk Spark blinks in surprise while you sit on the bed near her.

“Listen, how about you stop it but just for now?” You continue. “Ponies are getting suspicious in this hotel already. We have to cover our tracks. I don’t think you can grow more in here… And taking size from ponies we can meet at home could make ponies suspect you too. So I say we should be patient now, and in three month we’re gonna make a trip to Canterlot where you’re gonna be able to go all out again. What do you say.”

Silk Spark remains dumbstruck at first, but then a wonderful, slightly devious grin.

“Oh, I say we can plan it all out later.” She purrs. “First let me show you how glad I am that we’re on the same page.”

Silk Spark pounces on you, too strong and heavy for you to push away, but you had no plan to deny away the now bombshell of a mare anyway. You didn’t leave the hotel room for this last day.

 

A few years later, you would marry Silk Spark who had reached double your height. Nopony had found out how she did, but the magazines called her the mare whose puberty never stopped.

And indeed, Silk Spark had no plan to stop growing yet.
