It was probably a mix of of the collar's subtle influence, Megatron's own burning arousal and tiredness, and the fact that admitting wasn't begging. Further, he hardly had any issues with admitting... demanding, even, to be spiked. He could do either side equally well, but currently, as those cables slid out from their sockets and he couldn't quite keep the full-body vibration from escaping him, what he wanted, what he needed was... those.

Linking up to exchange and share energy and sensory feedback and looping it was of course a thing you could do quite easily, but even taking away the basic sort of connection and link these jacks and ports created, they simply seemed to work on a different level than the standard set of exchange linkups.

"No? Perhaps you'd like to enlighten me then---" His vocaliser clicked and fuzzed off as he was suddenly hauled up in the air and neatly deposited on Optimus' lap. Megatron's optics narrowed as he shifted around, but the curl of the cables around his limbs - almost perfect - made it hard to be completely annoyed.

"What's the point, or do you want an explicit invitation?" Mocking little snap in both voice and the tilt of his helm as Megatron gave into that pulsing, flickering need-heat and opened up... nearly all of the ports. The plates covering his spark chamber, and thus the final three, stayed close even as the Highlord of Cybertron twisted in the grip of those cables, just to feel the scrape of them against his metal.
