Optimus hissed silently; the sound of his engine and his own servos straining against the cuffs gone unusually loud with the lack of words.

Stubborn glitch. He just wasn't going to stop! A part of Optimus was surprised the mech was willing to go face-first to attempt to work his panel back open, but at least that meant he wasn't harassing his audials any longer. For now, his anger was enough to keep the pleasure from that warm lick at bay - but it wouldn't last.

He offlined his optics to keep the sight of a mech's head between his legs out of his processor. Seeing it was just as bad for his Consort libido as feeling it.
