::I'm quite gentle, really.:: Orion laughed, engine purring as he repeated the gesture on a more significant portion of Megatron's lip; less delicately than before, but nowhere near any level that might cause pain.

He certainly wasn't interested in that.

More interesting was the hand at his aft. He moaned around Megatron's lips, thighs splaying in the huge mech's lap to expose more hip joint - and interface paneling - to examination.

::But I'm not certain what you mean?:: The question was coy; he could guess, most certainly, hand at Megatron's jawline shifting to trail a thumb along a prominent neck cable pointedly.
