Chapter Text
Face down in pillow, one hand on Mumbo’s hip keeping him there… those panties just dragged to the side, for Grian to run his fingers against his hole teasing the man… probably not as much as the cock ring was doing. It was buzzing away gentler now, keeping Mumbo just mindlessly bucking once in a while, as if it would finally let him cum. “Good boy, keep that ass nice and high for me.” Grian coached as he pressed in a single slick finger.
Mumbo shuddered and pressed back before bucking forwards again. The man was whimpering, almost crying mess, his cock continuously dripping, soaking his panties. “Sir…” He managed before rocking again, already fucking himself on just the one finger. “Please.” He groaned weakly before burying his face into the pillows.
Grian gave him a swat on the ass, seeing his pale skin bloom with the strike and the way Mumbo cried out just made Grian ache. “Good boy… You are so pretty like this… So fucking beautiful like this. Just an eager little slutty puppy with a needy little fuck hole…” He purred and gave him another swat. Grian wanted to turn his ass the same red as his panties. Grian rubbed his well smacked cheeks. Mumbo shivered at the touch, confusedly rocking as if he didn’t know what his body wanted. “Oh yeah… I wish you could see how fucking beautiful you look right now. You are so fucking sexy.”
Mumbo whined lowly, his voice now a hoarse whisper. “Oh fuck Sir… Please… I… I am just…” He broke out into a loud whine, grinding back on Grian’s rocking finger. The slick noises of him being filled almost echoed around them as Grian fucked into him hard and fast, giving Mumbo no break. He didn’t deserve one or probably wanted one. Not when his cock twitched and dripped like that.
Grian added another thing, stretching him open roughly, driving little eager whines from his partner. “You are just a good little slut for me.” He informed him, quickly going to three fingers, bullying the third in making Mumbo gasp and spread his legs wider. “Good boy, you just want to be fucked and filled don’t you? Just begging for my cock.” He grunted, and curled his fingers upwards to brush Mumbo’s prostrate but only a teasing brush.
“I’m…” Mumbo managed wetly, sounding just almost out of it. “Yessssir.” He managed after a weighted moment. Grian tried to help him by pausing his fingers but instead it made Mumbo rock harder. “Oh fuck… please… more… just…” He whined louder now. “Please… Sir. Fuck…” Mumbo rambled, trapped cock aching.
Grian pulled his fingers out before settling properly behind him. “Don’t worry puppy, I am going to give you everything you want and more.” He promised, before grasping his cock and rubbed his cock against Mumbo’s hole… not entering yet even though he could feel the way Mumbo’s hole twitched begging to be filled.
Grian didn’t wait for Mumbo to answer before he moved and drove his cock into his body, feeling the way his hole almost crushed his cock. He was so damn tight still… even after 3 fingers and a lot of lube. Grian didn’t wait… didn’t let him adjust before he thrusted hard into him. “That’s it, baby… so fucking tight… I am going to fuck you open… shape you to my cock.” He told him and ground into his body. “Make you mine inside…” He told him, not even sure if it made sense at this point. He was just doing his best to thrust, do dirty talk and not just cum immediately.
Mumbo was still face down and whimpering with every hard thrust, driving him almost into the cushions as Grian did his best to use him. “Yesssssss.” He managed eyes shut, face all pink. He looked almost fucked stupid. Grian felt so fucking proud for being the one to do that. To drive his partner to the brink, to fuck him so stupid that he was just a babbling fool.
Grian grabbed Mumbo’s hips hard enough to leave bruises as he pulled him back to meet each punishing thrust. He realised that he should have put a leash on Mumbo, to give himself something to hold on to, and choke the man as he used to pull them back onto his cock. “You ready puppy?” He asked before fumbling with the cock ring around Mumbo’s length, turning it onto high.
The effect was almost immediate. Mumbo bucked hard and Grian held onto his hips the best to keep his cock inside of him. He felt Mumbo’s orgasm more than his own, as the pair didn’t last too much longer, with Mumbo clamping down on Grian’s length as they both finished.
