Getting jiggy again

Soarin got dressed in his BDSM wear and eyed up the slutty mare flicking her tail every once and a while, revealing her entrance wich turned him on. He chained up Spitfire’s hooves to the posts of the bed, spreading her legs apart.
“Oh, look what we have here, a bad slut that needs to be punished,” Soarin said in a sultry voice while smirking.
He started by slapping her ass, causing her to cringe and moan in a mixture of pain and delight. He then continued slapping her cheeks as his tongue danced on her folds, moans increasing in intensity. He started slapping more frequently as his tongue sunk deeper into her tunnel her moaning started to be more frequent and high pitched and squealed when he found her clit. He seized licking and slapping her butt. he reached for his side table for a whip
“ Ass slapping doesn't seem to be punishment enough, you fucking cunt.”
Spitfire screamed both in agony and ecstasy as the leather pounded her ass. Soarin increased how hard he swung at her. Spitfire yelled loud enough for the entire barracks to hear. Soarin grabbed the gag he reluctantly forgot to put on Spitfire’s muzzle and put it on.
“ Quiet, bitch, we don’t want anypony walking in on this, as even more kinky as it sounds. We could get in trouble for getting caught banging in the base.”
“Mmmphh,” replied the gaged Spitfire.
Soarin quit whipping Spitfire as he stuffed his member in her lover’s mouth. He sped up and started to play with one of her tits in one hoof and slapping her ass with the other. Going in deeper, his balls slapped her mouth as he moaned in delight as his member was being coated with saliva. He pulled out and stopped slapping her ass.
“ Now since you’ve been a good slut I’m going to rut you hard and fast,” said Soarin in a seductive tone.
He mounted his mare, slowly at first, he didn’t want to ruin the moment too soon. He continued to slap her ass harder than before. With the combination of the two, Spitfire moaned with a muffled tone from the gag. He pushed harder and faster, sinking in a couple inches down her tunnel, causing the two to moan more intensely. He pumped now even harder, hitting her clit causing Spitfire to make a muffled scream of pain from the ass slapping and rutting. They both came in ecstasy as Soarin was unable to continue to slap her from the intensity of the orgasm.
He unchained her and they both lie together, panting from the act, as he was able to gain his breath before starting to speak again,
“So how was it to be submissive,” asked Soarin
Spitfire huffed then replied,” Surprisingly, it’s a little better than being in control. What with being insulted and painfully pleasured and defenseless, it brings out another side in me, and that turns me on more than wearing silky lingerie and whipping somepony senselessly.”
