I did actually intend for it to be read as multiple dicks lol ;) glad you caught onto that. Maybe they’re slightly translucent so you can see eggs travel thru while breeding their mate? I also imagine they’re kind of prehensile and soft in the way that they can move to further push inside. Him stuffed full of as many tentacles as possible, taking clutch after clutch with eggs, his protoform and valve expanding and stretching to accommodate?

Sunstreaker bundled up safe and snug in the hive's nest, attendant drones making sure he's comfy as he's constantly mounted and bred full of eggs...

Being empty aches, he's unresisting as the next insecticon climbs on his back and he feels the inquisitive little tendrils probing his slit. His now constantly-dripping valve is spread open, larger tentacles gliding into him effortlessly. The aperture of his tank can't close anymore after laying so many eggs, and the ovipositor is right on target as it starts stuffing Sunny's tank with them, hundreds of squishy little orbs that will spend weeks growing inside him

Finally, the insecticon gets to the best part: making sure the eggs are fertilized with lots of transfluid and ignited by lots of Sunny's overloads. Dozens more tentacles invade his valve, writhing against his walls, as the iris of his tank is stuffed with the tips of as many as physically possible

His first overload hits him hard when he feels the transfluid spraying into his tank, but the insecticon uses the opportunity of his flexing valve to stuff it with even more tendrils. Sunny never gets any time to recover as the tentacles target his internal nodes, firmly pressing into every sensor as his valve is filled to max capacity

The insecticon stays locked on his back for days, the wriggling tendrils in his valve never stopping. When it finally decides the job is done, there's one last step before it can dismount...

A tentacle spends the final few hours filling him with a jelly-like fluid that will harden and plug his hole, keeping the eggs inside him until they've grown large enough to survive without incubation. Poor Sunny can't have anything else in his valve anymore, but there's always an attendant sucking his outer note to make sure the eggs still get energy from Sunny's overloads

When the plug dissolves, the eggs spill out of his loose valve, warm with newly-ignited sparklight <3
