Chapter Text
"I've always wondered Anon... Who was bigger. me-"
he stood in front, his pelvis near and Your arms tied behind Your back, belly pressing against the bedroom wall.
"Or a Centaur?"
He brought The toy to Your face, dripping with lubricant, as were You. He went to Your backside, one large hand fingering Your mouth, making You taste his rough scaled skin as claws raked softly on the tongue. A slap to the rear earns him a groan from You, satisfying to his ears and spreading You apart with the toy.
You two had made a bet. You win, and He has to go a whole day without release with a plug up the ass.
He wins, You have to be his personal seat for a day. Which wasn't that bad, You loved when he sat on You're face.
You felt it prod against You, lube spilling out in gushes, feeling full already from the pumping machine having prepared You before, a makeshift pressure washer retrofitted just to speed things up when You and him were in the mood.
The head disappears inside, You squeeze hard on instinct.
"Slut. Just taking it like a damn champ aren't you?"
You blushed, the head going in further. Inch after agonizingly slow inch, careful not to just ram it inside even though he knew You could take it. You had him in the bag, and he'd be your's to do with as You pleased for the next- wait....
You felt two distinct things below rest against You. That means!-
He started rubbing the XXXL toy in circles round and round, You barely made a noise even as it shoved against Your spot, getting a few moans at most. You felt him grinning before that massive face rests against you, whispering into Your ear.
"You lose..."
Fuck! He was bigger. He was actually fucking bigger than a- Jesus Christ that meant he was actually huge, way bigger than should be humanly possible to take. Granted it took a long, agonizing time to fully take him rough and fast to the hilt.
It started slipping out of Your well trained insides, pushing hard before hearing it fall to the floor and splash against dripping lube.
"Hope You like Being a chair."
You felt him grip You, rubbing between Your cleft, already lubed up and ready to show you just how small those pesky little Centaurs were.........
"OH GOD! OH GOD! HOLY, GOOD GOD HE'S-"
Your thoughts scrambled, Brain fried with pleasure as You clenched hard around him pummeling into You. You saw the outline of Your stomach bulging into the wall, skin rubbing against it with every deep thrust. Wet slapping and squelching, Lube slick and pooling into a waterfall of clear, sticky liquid.
"Can that little Horsie fuck You like this!" He panted, his muscular arms around Your neck, Your hands grasping his forearms for dear life as thrusts that moved Your entire lower body forward slammed into You.
After he was done choking You awhile, he grabbed Your head and held You up by it. His hips deep against Your back, Your arms limp and tired as he used You like a fleshlight.
"Tighten up slut! Show me Your not just a whore who bends over for any Monster looking for some ass!" He growled, slapping You hard and earning a scream out of You tired lungs, vocals sore from moaning.
You clenched Hard but his thrusts only spread You open so wide it was useless, his hands spanking Your obscenely bulging stomach, the imprint of him pressing it outwards.......
You changed positions, he now had You held up with his tail and hand, ramming inside You sideways.
"Can Centaurs Ungh! Fuck You like this?!"
He started pounding even harder. He already found You so attractive he came fast, resting his pelvis on Your hips and audibly pumping inside with a groan.
Your belly gurgled, filled up with him and bulging out, monster seed pumping You near to bursting........
He watched the Game whilst You laid down in bed, head pressed into the sheets and taking in that pungent scent with glee.
He had just finished lifting and was sweaty, his perspiration sticking to Your face, scenting You with himself.
He ground back, only shifting slightly to let You breath ever so often, before placing as much weight as he could on Your face. His tail wagging smugly above You, the announcer on the interspecies TV Network yelling as someone scored.
"Enjoying being my seat, You dirty Musk-Slut?" He growled out, grinding back and forcing Your nose deeper between and closer to his depths, forced to huff him.
"Jesus! He was so musky. Losing my mind...fuck.."
He shifted once more, Your nose going inside and burning with his masculine aroma that destroyed any semblance of inhibition, Your hips thrusting into nothing as You felt the touch less pleasure accelerate through You're body.
"Cumming! I'm fucking gonna cum from this!"
You thought frantically, not Your exact words, but that musk was rewriting every sentence in You're brain so much, smell so overpowering You were shocked to be still conscious.
Your pleasure Took hold and You bucked upwards, moaning into him as he rumbled, pleased and squeezing hard. You Heard sloppy splats hit the floor, his own pleasure hitting him as he came.
"Jesus Christ, I'm such a fucking...."
He tensed and clenched, body trembling ever slightly, Your tongue licking up his sweat and taking in his strong, foreign taste, air low and head light.
You blanked out, greeted to the sight of him hugging you in his arms, nuzzling You and making sure You weren't completely drunk on Alien pheromones.
"You smell like ass. Heheh...let's shower..." He said, trilling out the last part and carrying You.
One warm shower, his hands over You and scrubbing You.
You returned the favor. Especially on his ass, taking Your time feeling it and scrubbing it clean.
You cuddled with him wearing a bath robe, falling asleep together......
