I think about this a normal(lie) amount for Primus and Unicron. Because these mfs are so fucking huge, they have nothing to brace against except each other and their own gravity cores. In fact, I like to think that Unicron has to clamp onto Primus' limbs and drag him in while firing his thrusters whenever he spikes his brother. And Primus would have to disable his gravity well and succumb to his brother's pull.

Maybe to compensate from the inertia, Unicron's spikes (plural because I bet he has more than one model) definitely have prehensile self thrusting mechanisms to pound Primus' pussy, which would have magnets and rollers to drag that fat cock deep inside for sure. Maybe they'll find a stable orbit around a star before they settle down to fuck, or maybe they don't give a shit and just fuck while drifting through the universe, obliterating whatever insignificant poor bastards in the trajectory while they're lost in their lust.

Another headcanon I have is that each meta class of Cybertronians actually experience the passing of time differently. So a regular mech's vorn is like a quartex to a titan. This would mean that a single round of sex between two cybergods may outlive the lifetimes of multiple stars before either of them even cum, so it's not that Primus is taking forever to birth out their babies; it's that the babies are growing up so quickly, mommy is literally still in labour by the time they've faced multiple incidents of Armageddon and threats of extinction-🔌

aaaah yes I love that actually... their zero gravity planet sex takes down stars and galaxies, they're just so huge they barely register anything around them... Unicron and Primus just live for so long, mommy hasn't even stopped giving birth and the babies are already all grown up and scuffling. Poor little things, only alive for what seems like a few hours or days to Primus and already so silly with their civil wars, so strong.
