Automatically clamping his hand down right after Optimus jerked his hips up, he cursed his divided attention. He'd been more concentrated on several other things (like making sure his hand was in the way for the panels, stroking that stomach grille, and kissing Optimus) than paying attention to the strength he used to keep his hand where it was.

Drawing back to give Optimus' nasal ridge a bite, he dove into another kiss, grumbling quietly.

::That may be true, but while my favourite method in a situation like this is to inflict several overloads in a row on whoever I'm with, this time that isn't the aim. So no, I'm not going to 'get on with it'.:: Even Megatron's comm. voice was a quiet, pleasant purr, and now, in addition to pressing down with the hand laying over Optimus' pelvic armour with enough strenght to hopefully keep him from thrusting up into anything substantial, Megatron further angled that arm a bit so the spike wouldn't have a chance to rub against anything.

What he wanted to do was build Optimus up higher each time he paused, making sure he didn't overload until that very last moment. Thus, he couldn't have several overloads going on, no matter how tempting.

::I know it might be a bit much to ask, but patience, please.:: Megatron had a feeling that he'd come upon the wall of Optimus' patience when it came to being aroused and things taking "too long" to get to overload however.

That didn't mean he wouldn't give his Prime a chance to rein himself in.
