He felt awkward kissing Optimus. Not just because of the gag, but it certainly wasn't making things easier. No, it was just too close, and if he could have gotten away with something less... intimate, he would have.

But Optimus certainly liked kissing, so maybe it could make up for things slightly. Grunting into the kiss as Optimus' valve closed around him, Megatron's optics widened as well. This time he was alert and aware enough to tell...

His engine briefly worked into a straining whine as every little bump, calipher and filament seemed to close around his spike just so, and this was not normal.

Stroking his tongue over the roof of Optimus' mouth, Megatron drew his hips back and then pushed in again with a slight rolling twist. This was just not normal, because even if you had the luck to fit well somehow, and long familiarity between two or more individuals usually rearranged the structure of valve and spike slightly, this well, this soon, should simply not be...

Groan swallowed into their kiss, Megatron had a hard time not jerking away. Too close. But he stayed, even as every single still-covered port flexed as he carefully fed a tiny more amount of charge to his spike as he drew out halfway, and snapped inwards.
