Starscream was still furious with Megatron for siding with Shockwave during an earlier argument. But he’d never been one to turn down a frag. So he stubbornly kept his mouth shut as Megatron thrust into him slowly, gently. He braced himself on his forearms over Starscream and dark red optics squinted down at him.
“You’re quiet tonight,” Megatron rumbled. He paused in his careful thrusts, bowing his helm to ghost scarred lips over Starscream’s delicate throat cables.
Any other night, Starscream would have lost himself to the awe of these rare moments when Megatron was gentle and attentive, even borderline vulnerable. Tonight, however, he glared up at his much larger partner. When he didn’t answer, Megatron’s expression hardened, guarded once more.
“If you didn’t want this,” he growled, slowly easing out of Starscream’s tight heat, “you should have stopped me.” He pulled away to sit on the edge of the berth they sometimes shared. His spike curved towards his belly, throbbing and leaking prefluid. He didn’t touch it.
Starscream let out an irritated huff, his valve achingly empty and his slender spike twitching. He snaked a servo down himself to massage the tip of his spike. Megatron’s help whipped to the side, his optics locking on Starscream’s servo. He snarled, expression dark, and snagged Starscream’s wrist away from his spike.
“What do you think you’re doing?” Megatron snapped.
Still, Starscream bit his tongue.
Megatron bared his fangs. “Fine,” he growled. “You’re mad at me.” He shifted on the berth, shoulders pressing Starscream’s thin thighs open wide enough to burn. Megatron dipped his helm, licking a slow stripe from the bottom of Starscream’s valve to the tip of his spike. “But you do not get the privilege of ignoring me. Ever.”
Starscream shivered, fighting back a moan when Megatron swallowed his spike to the hilt in one quick motion. He felt the slightest bit of guilt, but he was still hurt over Megatron almost allowing Shockwave to harm him.
Megatron worked his intake over Starscream’s spike hard and fast, his frustration bleeding into his denting grasp on Starscream’s hips. He scraped his dentae carefully over his small partner’s spike, finally eliciting a sharp cry from Starscream. Megatron doubled his efforts, slipping one servo down to piston two digits deep into Starscream’s leaking little valve, thumb rubbing harshly at his exterior node.
Starscream arched off the berth, optics blowing wide from the overwhelming pleasure-pain of the dueling sensations. He couldn’t stop the high pitched whine that escaped him. His servos gripped Megatron’s helm as his hips thrust frantically into the larger mech’s hot mouth. His cooling fans kicked into overdrive and he trembled, teetering close to overloading.
Megatron completely detached from Starscream’s array, a cruel grin stretching his lips. Starscream whimpered, hips desperately chasing after Megatron’s digits and mouth.
“Oh, were you close?” Megatron taunted. He made a show of sucking the fluids from his digits. “If only you’d told me.”
Starscream groaned, writhing uncomfortably on the berth. “Megatron, please,” he whimpered. “Please, Master, I’m so close—”
“Enough,” Megatron barked. He lifted to reposition himself, lining his spike up with Starscream’s weeping valve once more. “You will not shut me out again,” he commanded, driving his spike home in one brutal thrust. “And you will overload when I allow you to.”
