Orion jerked at Megatron's retaliation, unable to muffle his answering groan. The sharp pleasure surge around his spike and cable-tips was all the stronger for it's unexpected nature.

So he laughed, dragging spike and tentacles out against the resisting tightness.

"Congraduations, Megatron. You've finally surprised me."

He arched up, murmuring in the other mech's audial and throat, biting at a line.

"I like it. Too bad for you 'other half' doesn't mean full control. And I'm the one with the far more useful variation."

He punctuated the words by wiggling a cable out of Megatron's shoulder and having it curl along his chin in a taunting caress.
