Fighbird found himself enjoying the thing he had seen in Dash Max's human movies. It was just a little test of his, one that he hoped he could perform smoothly. Judging his senpai's reaction, he was doing very well, though his jaw was a little tired.
Kneeling between Exkaiser's thighs, he sucked on his superior's pressurized cord. Helm bobbing at a slow pace, he watched as Exkaiser bit into his red knuckle joints to hide his sounds. One servo rest on Fighbird's helm, rubbing affectionately around his audial fins as the mech sucked him off.
Exkaiser's feet were propped on the desk, and he thanked whatever gods out there that everyone had left for the night. Anyone walking in now would get a full view of his frame arched and Fighbird's lips on his straining cord. He started to buck gently, careful not to gag the jet mech, and the hand over his mouth moved to grip the arm of his chair as he moaned deeply. That was exactly what Fighbird wanted, and he upped his pace to hear that sound again, humming a little. Exkaiser's optics dimmed, fans rapidly whirring to cool himself off as he continued to make short moans, hips jerking. Fighbird smiled a little around the cord in his mouth, continuining with his experiment until he felt Exkaiser's cord spasm and lubricant hit the back of his intakes. His loudest moan yet echoed in the room, and his frame tensed. Fighbird's glossae lapped at the underside of his cord slowly, drawing more soft sounds. When Exkaiser was reduced to shudders and panting, Fighbird moved to sit on his superior's lap. Exkaiser's servos placed themselves on the other's hips as Fighbird cuddled close.
"What...was that for, Fighbird?" the older officer asked, once his fans had slowed some.
The jet mech smiled softly. "I missed your voice all day, so I thought I would do something to hear it."
