Pairing: RID Drift/Grimlock

Rating: Explicit

Details/Themes: Rough sex, bondage, bestiality (in a sense)

The Dinobot whimpered in arousal through the muzzle he wore as the chain to his collar was pulled, bringing his helm down to be parallel with his master's. His tail curled inwards as he pressed his back against one of the shelves, slumping pleasurably as he watched Drift sink hard onto his spike. He couldn't use his servos to feel the samurai freely because they had been bound together while his legs couldn't exactly do anything except stretch on occasion, the claws of both sets flexing to grab ahold of something.

A servo rubbed the side of his helm soothingly. "My dear pet, your lack of restraint amuses me. I will let you take command eventually; you just have to be patient."

"Yes, Master," Grimlock moaned.

The samurai smiled at how well his student was being compared to last time they played rough and the Dinobot bit him to claim him as his own, thus hence the muzzle. The bite actually felt great but the severe mindlessness of it was a little disappointing. This time, he was training Grimlock to obey and learn self-control.

Drift grasped one of the chains that lined the Dinobot's chest to steady him as he lifted off the massive intrusion then pushed back down at a rapid pace, enjoying how it split his valve and hit clusters of nodes that he never knew existed. Peering behind him, he panted as he saw his reflection in several mirrors all holding delicious angles of his ride on the tyrannosaur mech. He loved how he looked, how his opening was so greedy for the bounty it was receiving.

His "teamy" could fill him better than his past lovers and that was one of the things Drift absolutely prized about his current companion. Shadow Raker was good but never made him feel like he was going to explode. Fracture was a one-time thing and that bot couldn't satisfy his lust either but then there was Grimlock. Bigger, stronger, faster, and rougher. There was no taking it easy with this mech; he was always a powerhouse in the berth and could break the limits his former partners failed to do.

Seeing the Dinobot in such a state of euphoria, growling and whining from the building overload, made him want to be a bit sadistic to heighten the experience. He smirked as he stopped moving and hovered his empty gaping valve over the large member, alerting Grimlock and making the beast snivel at the loss. Briefly, he shot a glance down and saw his transfluid stain the underbelly of the mech. A very beautiful sight. He used two digits to swipe some of it up and held its dripping contents up to the muzzled mouth of his lover.

"You're being such a good pet. Perhaps you deserve a treat," Drift mewled.

Grimlock's glossa slithered out, brushing the coated digits eagerly. The fluids tasted superb to him as he licked them clean in seconds. After he was done, Drift got off the tamed Dinobot much to the latter's dismay and undid the chains around Grim's servos freeing them. He gave his berthmate a wink before giving the leash two tugs signifying to get up.

"Master Drift, are we done? Please tell me we aren't. I want to make you call my name at least once today," Grimlock whimpered.

The samurai laughed, "Far from it, my pet. We are just changing course to your 'Dinobot style' as I believe it is time for you to take control."

Optics widened with glee as the Dinobot rolled onto his front to stand and enthusiastically pranced to his master's side wagging his tail like a puppy. When Drift nodded at him, he roared and pushed the smaller Autobot to a scrapped truck and made the samurai plant his servos onto the hood while his aft was presented. Grimlock snarled lustfully as he placed his own servos around Drift's waist and lined up his throbbing spike to the leaking entrance. His chest nearly rested on Drift's spinal strut perfectly. The orange and red mech still had the chain to his collar and pulled down on it to bring Grim's helm beside his again with a seductive purr which made the Dinobot hiss satisfyingly back.

Drift gave a soft moan when the spike filled him to the hilt, sensors in his valve lining surging like crazy. 'Dinobot style' was one of his most favorite positions because the animalistic sense it copied made him feel very unorthodox and the utmost desire to be fucked without restrictions. It helped that it also hit angles other positions couldn't.

Suddenly, Grimlock rutted against Drift vigorously. Thrusts were hard and quick, stuffing the samurai and stretching him beyond the normal limits. Drift didn't objectify to the treatment as he panted with a smirk and let the Dinobot roughly grasp the underside of his thigh to lift it for an even better angle. He could feel Energon joining the mix of fluids but it bothered him none as this was normal in their interface. The sting of the small rip in the mesh only drove him to move back to meet Grim's plunges and a new flare of pleasure rippled through his chassis.

"Grimlock! Grim-AH!"

Overload hit him faster than he anticipated and the pressure in his valve tightened to an unbearable level. He heard the monstrous bellow of his lover above him and the chain in his servo jerked upward before a marvelous warm rush of fluids filled him beyond his capacity. Flustered, Drift groaned as Grimlock left him open, dripping, and completely vulnerable. To be honest, he was unsure if he could walk properly for a while.

"You okay, Master?" The Dinobot asked with concern.

Drift breathed heavily with a grin, "I am more than alright, my pet."

Twirling the chain in his servo, the samurai could feel all the combined liquids trickling down his legs to the ground. It was a very welcoming feeling indeed.

AN: Grimlock's not actually his pet. He only calls the big guy that during sex whereas in public, they are a kickass team and they treat each other as such. I questioned what I could possibly do to make this pairing a bit kinky and ta-dah! At least I'll go to hell with my pride.
