Chapter Text
In the dim light of the containment cell slim wings flutter and twitch in involuntary movements while coolant rushes too fast throughout cables and around joints, in a vain effort to calm the overcharged seeker currently restrained there. If only Starscream hadn’t pushed Megatron so far this time, if only he hadn’t sassed back that last witty remark to him, then maybe he wouldn’t be in this position in the first place.
With his head hung low, knees becoming sore from kneeling on the cold, metal floor, he ponders when Megatron will come back and release him from this sickly sweet punishment he saw fit to drag him into. No matter how he tries to adjust his footing, the vibe in his valve and the too tight ring fixed to the base of his spike never relent.
Another rush of pleasurable charge runs up his spinal struts and he grasps harder to the chains holding his arms aloft over his head. He can’t help but tug on them and arch into where he’s bound to the floor by his legs despite the futility of the action. Wings flex higher and closer, tight to his form as that damned vibe cycles through its pattern again and lessens its incessant purring, leaving Starscream once again to go slack in his chains.
Transfluid weeps out of the tip of his tender spike and drools down to pool in between his thighs. Even with his valve’s codpiece closed, fluid leaks from between his thighs as well. He must have been in here for hours at this point, writhing on the vibe and bucking into nothing, hoping desperately to release the still growing charge that’s accumulated in him. But between the inconsistent patterns that the vibe stuffed in his valve cycle through and the tight ring on his spike, he just can never reach that peak despite being punched to its very edge time and time again.
Heavy pants come out of his mouth as his fans run on high, trying in vain to cool him down, as the vibe switched cycles again and starts to rumble harder inside him. He flexes his thighs and arms to draw energon back into them and is beginning to curse Megatron’s name when the door to the cell pings red then green, announcing a visitor.
Starscream can barely bring himself to lift his head to see his lord himself standing at the entrance, arms crossed and a terrible smirk on his face when he looks back at Starscream. He sees Starscream in the exact position he had left him in hours before when he started his shift on the bridge. Now, after his shift is over, he sees a new puddle of lube at his feet and a much more pliant and obedient seeker in his second in commands place.
Voice box strained from overuse, Starscream can only whimper lightly as Megatron comes closer and uses a hand to pull him further up onto his knees by his neck when he goes to a knee in front of him. No words are exchanged as Megatron runs a large paw down Starscream’s side, past his cockpit and over his hips, to reach behind him and grasp his aft.
Grateful for something to rest his weight on, Starscream leans into the touch and arches his hips into the heavy servo that massages the heated metal there. With two taps of a claw to his codpiece, Starscream opens and the vibe very nearly slips out along with the steady amount of lubricant that flows out. More whimpers follow as that same claw pushes in and adjusts the toy inside him so it fits snugly again.
Starscream swallows and his spike gives a halfhearted twitch as he relaxes into Megatron’s shoulder. Mind blank and broken, he’s forced to gasp out and pull at the chains restraining his wrists as Megatron forces two digits in his valve and goes to press the vibe directly against the overworked and most sensitive inner nodes in his valve’s deepest places.
Megatron smirks against Starscream’s neck when he buries his faceplate into his chest plate and he bucks back into Megatron’s servo. Gasps and shivers run through Starscream as his hips arch out and back, trying desperately for more friction. His weight settles lower into Megatron’s palm and not even the chains around his ankles can stop his writhing once Megatron's other hand comes to tease the tip of his drooling spike.
Within only an instant, Megatron lets up the pressure on the vibe, giving poor Starscream sweet relief for a second, when his other servo hooks a claw around the elastic band on his spike and snaps it off. The change is instant where Starscream’s whole form shakes and his wings shoot up into their highest position as Megatron pushes hard on the vibe and makes it purr deliciously right against his valve walls.
Transfluid shoots out of Starscream as he earns his name and shouts out in staticky yells his pleasure. His hips rock and arch against Megatron for a few clicks as he writhes fiercely until he goes strut-less in an instant and goes limp against his masters chest plate.
Megatron relents when the last twitches make their way through his second in command and pulls both his fingers and the toy out. Starscream is left venting heavily even after Megatron reaches a servo up to undo his restraints and even later, carries him away to his berthroom. His optics shade and cycle closed as recharge takes him away just as Megatron had.
