A few weeks later Leon and Big Mac were back to working the farm. It was a hard work as always but they quickly powered through it and got inside because today was a big day. It was Big Mac's birthday! And Leon had enlisted Sugar Belle to help make it special.

After they had finished working, Leon got himself cleaned up.
While Big Mac and the rest of the Apple family were having dinner, Leon and Sugar Belle snuck upstairs to Big Mac's room.
As the two got inside Leon quietly shut the door behind them.

"So what do you have planned for the big guy Leon?", Sugar asked as she walked into the room.

She got half an ansswer when she looked at the stuff Leon was messing with, BDSM stuff. Rope, tape, a pair of pink fuzzy handcuffs, a riding crop, a strap on,a bottle of lube, a ball gag, a candle, belt straps, and a block and tackle bolted to the ceiling.

But what really caught Sugar's eye were the two potions sitting on the table next to the bed.

"Leon... what are those?", she asked pointing at the glowing bottles.

"Those are the centerpiece of this", Leon got up and looked at the glowing bottles. "I had Twilight whip these up last week."

"What do they do?", Sugar asked, picking one of the bottles off the table. Inspecting it she found it was labled with her name.

"They're gonna make me and you swap bodies with eachother!"

"What?"

"Yah we sawp bodies, and then I get Big Mac to... you know, do YOU in MY body", Leon explained, striping off his clothes and trying to tie himself up.

"Are they safe?"

"Pretty sure Twilight wouldn't have given them to me if they were dangerous", Leon answered while he struggled with the ropes. Tripping himself up Leon fell to the floor in a tangled mess of rope and belts.

"You need a hoof?", Sugar giggled.

"Yah."

After a few minutes of tieing and cinching Leon, soon to be Sugar, hung from the ceiling.

"So do I drink this now?", Sugar asked holding up the bottle.

"Yes but feed me mine first", Leon answere while his body slowly spun in circles about two feet off the bed.

Popping the cork off Sugar stuffed the bottle in Leon's mouth for him. Leon tilted his head back and gulped down the potion, spitting out the bottle and smacking his lips. "Tastes like grape soda."

"How do you feel?" Sugar asked grabbing the empty bottle off the bed and swapping it for her potion.

"A bit dizzy, but that's probably from the spinning. Go ahead and drink yours."

Sugar popped open her bottle, looking closely at the fluid before shrugging her shoulders. "Here goes nothing."

Sugar Belle downed the potion and placed her empty next to Leon's, "So, how long does it t...."

*bam*

Sugar Belle suddenly collapsed to the floor un-conscious.

"Suger Belle? Sugar Belle!? Oh shit wha...", Leon froze and went limp, as he to lost consciousness.

After about fourty seconds Leon came to, and saw himself suspended above the bed. The potion had worked. He did indeed now inhabit the body of Sugar Belle. Leon got to his hooves and inspected his new mare body. Having already been a stallion, he quickly adapted to being a pony again... although with some new parts.

"This is awsome!", Leon covered his mouth with his hooves in suprise. "Holy crap I even sound like her!"

Leon spent a few seconds looking over his new body. Feeling up his new snout, main, hooves... pussy. Mostly the pussy.
Reaching back Leon started rubbing circles pleasuring himself. He lost himself enjoying the new sensations, compleatly forgetting about Sugar Belle.

"Having fun?"

Leon yanked his hoof away before spining around to see a now conscious Sugar Belle watching him with his own eyes.
"Is that you Sugar Belle?"

"No I'm Leon, the horny human. You're Sugar Belle", She corrected sticking her tongue out with a grin. "So how do you like my body?"

"Oh my god I'm adorable!", Leon cheered prancing about. "This is gonna be soo much fun!"

"Well don't just stand there, go get the big guy", Sugar ordered motioning to the door with her head.

"Right", Leon ran out of the bedroom and down the stairs.

Sugar hung there watching the open door, waiting for Leon to return with Big Mac. She was giddy with excitment when she saw a shadow approaching from outside. Her enthusiasm reduced when instead Applejack walked into view.

Looking into the bedroom Applejack found what she assumed was Leon's presenting himself to Big Mac for his birthday. Applejack looked at the boy and saw this as an opportunity to reverse her and Leon's roles from their previous sexual encounter. Her face contorted into an Grinch like grin as she stepped inside.

"Well looky here, somepony got a little too excited for bedtime", Applejack shut the door behind her.

"Applejack, some privacy please", Sugar asked.

"Right", Applejack turned and locked the door behind her. "I'm gonna take a shot in the dark and say you're lookin to be punished", Applejack grabbed the riding crop and gave Sugar's ass a few wacks. "I can do that!"

"Oweee! Stop AJ!", Sugar yelled as Applejack continued to flog her.

"Leon, you remember when Big Mac gave me over to to you for a night? You was a pony and I was human...remember?",Applejack punctuated her question with a particularly hard wack.

"OWW! Yah you were a jerk to Leon... I mean me!"

Applejack grabbed the strap on off the bed and fastened it to herself. "Well I think Big Mac can give you to me for the night so I can have my turn", she said, grabbing the ball gag off the bed and climbing in fronof Sugar.

Now well aware of where AJ was going with this, Sugar Belle decided to blow her cover to make her understand. "AJ I'm not Leon, it's me Sugar Belle. Me and Leon swaped bodies with those potions oveMMPHHHM", Sugar was interupted by Applejack cramming the gag in her mouth.

Cinching it tight at the back of her head, Applejack Leaned down and looked Sugar in the eyes.
"Shhh... There's no talkin me outta this Leon", Applejack ran a hoof over Sugar's face. "Just pretend I'm the big guy, you'll be fine"

"MPHHH-MMh-mmmhhh!"

Applejack spun Sugar around and moved between her bound legs. Reaching down she grabbed the bottle of lube off the bed and pulled the lid off and shoved the top into Sugar's ass. Applejack squeezed the bottle hard, and a generous ammount of cherry flavored lube went into Sugar Belle.

Pulling the bottle out Applejack used what remained to coat the strap on. "You rutted me pretty good as a pony Leon, so don't be too upset if I have you walkin funny for a few days."

"mphh!"

Applejack pressed the tip into Sugar's ass. Grabbing the ropes that wrapped around Sugar's back, AJ swung the bound girl all the way back into her crotch, burying all of the toy inside in one go.

"MPHHHHM!"

"Oh, quit your whining. This thing aint nowhere near as big as my brother"

Maybe not, but Sugar Belle wasn't used to being fucked as a human. The streching she felt while inhabiting Leon's body was like being a condom wrapped around a cantaloupe.

Applejack pushed Sugar away, and let her swing back into the base of the toy; an action she would repeat many... many times.

"Glad you hung yourself up like this Leon, makes rutting you a breeze. . . for me", Applejack rocked Sugar back and forth as the girl yelled profanities into her gag.

Oh Celestia, Leon please get back here quick!

{meanwhile downstairs}

"No Sugar Belle! Not here!", Big Mac yelled.

The human turned mare had crawled under the table while the family was eating dinner and attempted to "pleasure", Big Mac in front of his little sister and grandmother. "Get outta there!", Big Mac ordered, sliding his chair back and letting Leon crawl out from under the table.

"Aww, what's wrong birthday boy?", Leon asked as he got to his hooves.

"What's wrong with me? What's gotten into you all the sudden?! Crawlin under the table like a dog."

"Woof", Leon mocked with bedroom eyes

"Aww geez, a mare in heat. Alright let's go Sugar", Big Mac grabbed Leon and led him upstairs, not wanting the mare to continue her lascivious behavior in fron of his family.

Reserved as Big Mac was acting, Leon caught a glimpse of his cock peaking out of it's sheath when he walked by, and knew he had gotten him hot-to-trot.

As the two approached the bedroom, Sugar's/Leon's muffled moans and screams could be heard echoing through the upstairs hall. When the two reached the bedroom door Big Mac grabbed the knob and found it was it locked.

*bam bam bam* Big Mac banged on the door. "Who's in there?"

"Take a guess you big oaf", Applejack hollered, not stopping her fucking in the slightest.

Sugar, hearing Big Mac outside, did her best to call for help from her coltfriend.

"MPHHHM!"

"AJ open this damn door!", Big Mac ordered.

"Ummm let me think. . . . . no"

"No? What, YOU!" *bang bang bang* "This is my room girl!", Big Mac yelled, losing patience with his sister.

"Yah well I'm using it right now"

"For what!?"

"Bucking your pet human"

oh shit, Leon recognized what must have happened and felt bad for Sugar Belle.

"AJ we've been through this, you leave Leon alone!", Big Mac yelled.

"Just getting even with the little horn-dog, Don't worry big guy I'll be done in like.."

*BAM!* Applejack spun to see the bedroom door get kicked clear off it's hinges.

"Yer done now!"

Applejack quickly pulled out of Sugar and put her hooves in the air. "Ok-ok... I was just getting the little guy warmed up for ya", She joked smacking Sugar on the ass. Pulling off the strap-on, AJ hopped off the bed. "Lookes like Big Mac don't wanna share ya", she said giving Sugar's ass a smack.

"I don't think he's like that for you", Big Mac remarked as AJ walked past.

"Probably not" Applejack agreed in a nonchalant tone. "Happy birthday big bro."

Big Mac relaxed, rolled his eyes and smiled, "Thanks AJ. Now get outta my room."

After she was gone Leon ran up next to the bed, "You ok Sugar?", he wispered.

"mm-hmm."

"Great cuz I got Big Mac ready for ya."

"Mphmm?"

"So Big Mac, you wanna un-wrap your present?", Leon asked pointing at Sugar.

Big Mac walked over to the bed and grabbed ahold of the pullys suspending Sugar and started hoisting her higher into the air. "Leon can wait. He just had a go with AJ, plus he's not the one who just made a move on me me off in front of my granny."

Sugar now looked down at them in confusion as Big Mac grabbed Leon and tossed him onto the bed. "I'm gonna take care of you first. You need this a little bit more than he does"

Big mac climbed on top of Leon and placed his raging erection at the human turned mare's pussy.

"MPHHH! >:(", Sugar yelled, thrashing around above them as the two prepared to copulate in front of her.

Big Mac looked up at his swinging friend. "You'll get your turn Leon, but Sugar's in heat right now."

Sugar was angry, curious, and starting to chafe, but she would be lieing if she said that this turn of events interesting.
A part of her wanted to see herself get bucked from somepony else's point of view.

Big Mac bucked the first half of his length into Leon's pussy, making the human turned pony writhe in feminine pleasure while the larger male above him bucked away missionary style.

The position seemed akward for Leon being a pony, but he wasn't going to say anything other than, "YES" and,"MORE" and, "I never wanna go back."

"What, no foreplay?", Leon asked Big Mac who ignored him and continued thrusting unabated. Leon didn't really care. For him, having sex as a mare was cloud 9. He never knew pony girls felt this good.

Being taken by his lover as a real girl, and having Sugar watching while Big Mac humped away at what he percieved to be his marefriend was super hotvr. Leon moaned and looked up at Sugar with a coy smile as she watched the human in her body having the time of his life. But then she went wide eyed in terror noticing the telltale signs of her lover approaching climax.

"Do it Big Mac do it. . . do it! FILL ME UP!", Leon begged.

Leon you stupid...!You're gonna get me pregnant!

"Really, you sure Sugar?", Big Mac asked.

"YES!"

"NO!", Sugar tried to scream but... you know, the gag.

Leon held on, wrapping his rear hooves around Big Mac's back as he locked lips with his lover.

Big Mac gave a final, heavy thrust, and buried his cock deep, plowing straight through into Leon's womb. The tip of his cock flared out, locking Big Mac into his marefriend. Leon squirmed in ecstasy as the cock pulsed and pumped tons of viral pony seamen directly into his... Sugar's...

Uh-oh.

"PULL OUT!", Leon yelled realizing what he had done.

Big Mac lightly tugged a couple of times, but the well endowed pony knew it wasn't going anywhere.
"Sorry, too late Sugar."

The two lay together while his cock slowly softened. Big Mac intended to spend awhile there, but turned around when he felt something dripping on his back. Looking up he saw Sugar sobbing above them, her tears were falling down onto his back. His cock, now soft enough to come out pulled free as he stood up on the bed. Some cum flowed out of Leon's pussy but the majority of it remained trapped inside.

Big Mac brought himself to eye level with Sugar. "What's wrong little guy?"

"mmphhh-mmmmm"

"Oh right", Big Mac undid the buckle and pulled the gag from Sugar's mouth.

"You big dummy!", Sugar cried.

"Huh?"

"You let Leon get me pregnant!"

"Huh?"

"Me and Leon swapped bodies."

"Huh?"

"And you were supposed to do me not... him."

"huh?"

"LEON! SAY SOMETHING!"

Leon gave some incoherent, cum-drunk mumbling before rolling off the bed. When Leon hit the floor some more cum blew out of him and pooled onto the bedroom floor.

Sugar Belle hung her head, "UGGH, why does he always take the creampies?"

Big Mac rubbed his head, "You're gonna have to walk me through this Leo.. I mean Sugar Belle"

"Can you get me down first?"

Leon reached back and grabbed the empty potion bottles still sitting on the table and handed them to Big Mac. He read the names printed on the sides and things became clear.

"Sooo, you're Leon and you're Suagr Belle?", Big Mac asked pointing at them.

"Right"

"So how long are you gonna be my marefriend for Leon?", Big Mac asked, grabbing his little pony and placing him in his lap.

Leon rubbed up against Big Mac's broad chest, "however long you want birthday boy."

Sugar Belle was going to yell something about how SHE was Big Mac's when she realized Leon hadn't told her when they would swap back. "Leon how long are we gonna be like this?", She asked, fidgeting around in Leon's body

"It's permanent", Leon said as he curled up like a cat on Big Mac's lap and closed his eyes.

Sugar moved across the bed and brought herself down to Leon's face "What?"

"I mean it lasts until Twilight finishes the counter potions."

"When'll that be?", Big Mac asked, petting Leon like a cat, making him even more comfortable.

"Maybe next week? I'm not in a hurry"

"Next week?!", Sugar exclaimed grabbing his face with both hands. Leon, I'm not staying in your body for a week!"

"Why not Sugar? Let the boy be a mare for a little while."

"I'm not leaving him in my body for a week. He's a mare for one night and he's gotten himself knocked up!"

"We don't know that yet."

Sugar Belle poked Leon's belly, and Big Mac's cum could literally be heard sloshing around inside. "Preggers."

"Well truth be told Sugar Belle, I've been wanting to have a foal with you for awhile now", Big Mac admitted running a hoof along Leon's belly.

"Really?", Sugar asked in confusion. "Then why didn't you ever say so?"

"Every time I asked, you wanted muh seed outside"

"I always said outside because you asking made me think you were worried about it"

The two of them stared at eachother in silence for a moment.

"So what do we do now?", Sugar asked.

"Let's go to bed, it's been a long day"

Sugar crawled under the covers with Big Mac, who then placed Leon inbetween and pulled the three of them together like a love sandvich.

"What are we gonna do tomorrow?", Leon asked.

Big Mac closed his eyes, "I don't know"

{the next morning}

"Wake up yall!", Applejack yelled from the bedroom doorframewith the door still on the floor. "I know you horny ponies wanna spend all day in bed, but we still got a farm to run." Walking inside Applejack ripped the covers from their bodies. "Get up!"

"Aight lil sis we comin", Big Mac moaned as he stirred from his sleep. "Get up Leon we gotta, oh... right", Big Mac remembered their situation and got himself out of bed. He turned to his sister, "these two are gonna need some time off, so Im the only working man you got today."

"Why?"

"You don't wanna know", Big Mac warned as he put on his collar and went downstairs.

Applejack looked at the two still sleeping in the bed, "Geez it stinks in here."
