I Know We Have Been Talking About Prime! Optimus Having Baby Fever, But What About… Earthspark Optimus

I know we have been talking about Prime! Optimus having baby fever, but what about… Earthspark Optimus with baby fever?

The Matrix wants someone in particular though, that big, strong silver mech who just so happens to have been more friendly with Optimus lately… he'd make such a good sire, filling the Prime with big strong cybertronians, like Primus intended

Hell yeah! I love me some earthspark megop :3

Optimus has been feeling strange lately: craving touch, feverish, and his forge aches. He knows he's charged up and in need of a good frag, but it's never felt like this. The Matrix is messing with him, it's the only explanation - its been begging him to frag and getting angry with him when he attempts to stave it by self-servicing. He knows what it's calling for - a sparkling, and not just anyone's.

Megatron's sparkling.

It's not like the two haven't interfaced before, or even been romantic together, but it's never been made official since after the war. Optimus suspects Megatron feels inadequate, and that if something bad were to happen in a potential relationship, any progress towards peace would be lost. It makes Optimus sad to see his dear friend like this, and offers him comfort and support, but the road to recovery is long and bumpy.

So he deals with it himself. He's a big bot, he can take it! Even if it infuriates the Matrix, he'll wait it out. Even when he feels achingly empty. Even when all he wants is to curl up next to Megatron and fall into recharge with him. Even when he weeps in his room at night because he's so frustrated and horny, and he loves Megatron so much but can't have him.

He didn’t realize that the Matrix was affecting Megatron too, though, because that big, strong mech he’s been dying to clang the bolts off of pins him against a wall one day, panting heavily, optics wild with lust and he’s growling - oooh sweet Primus he’s acting like a wild animal and Optimus melts in his arms. The Matrix is singing with joy, flooding Optimus’s processor with “strong mate”, “safe, protected”, “sparklings will be healthy” and Megatron’s thoughts swim with “protect mate”, “perfect, submissive, sweet” and “good carrier”. Megatron smells of training - fuck, isn’t he so strong? And Optimus smells delightfully sweet.

Megatron practically drags Optimus into his room and pins him on his berth, roughly inserting himself into his valve - somehow he just knew that Optimus wanted it rough. He holds Optimus’s shapely hips and begins pounding into him like his life depends on it. Optimus is wailing and moaning, so overwhelmed by how good it feels - so good to give in and finally get what he wants, he doesn’t know how he possibly made it by with just self-servicing. It’s both so much and just right at the same time, and before he knows it warmth blooms in his abdomen as he’s filled with transfluid. He begs for more, he needs to completely filled, he turns to look Megatron in the optics and pleads, low and desperate, to be bred. As if he couldn’t get more charged up, Megatron fucks him with wild abandon, making his mate cry out. After several rounds, Orion’s valve catches on Megatron’s swelling spike and fuck - he has a knot, he has a knot and the Matrix couldn’t be happier! There’s no way he won’t kindle now.

When Megatron’s knot deflates and he pulls out, he cleans Optimus up with his mouth. Poor Optimus has no energy left, softly moaning and trembling slightly as his sore valve is gently swiped over by Megatron’s mouth. He closes Optimus’s panel manually and whisper to him, “Sleep, dear. You’ll need it.” and Optimus allows himself to slip into recharge. Megatron cleans himself up and deals with some responsibilities, making sure to come back when Optimus wakes up. He kisses his forehelm and treats him like a delicate flower, as if he wasn’t just rearranging the Prime’s internals just half a solar cycle earlier. He presses a servo to his mate’s middle, feeling the warmth he was looking for - Optimus’s forge has kicked online.

A few weeks later they still haven’t looked into Optimus’s spark chamber, too worried that they’ll jinx it. But when his abdominal plating distends outwards ever so slightly that’s when they know for sure.

Megatron’s the best sire a bot could ask for - he’s powerful and strong but so considerate and gentle. He finds the whole situation quite poetic.

And if you’ll excuse me, I’m gonna go think about this FOREVERRRR
