#robot balls

They jiggle slightly when he trots on all fours. The fact that they sit right there means he feels them when he sits. Usually that isn't a problem, but when he goes into a heat or a rut and his balls get all tender and swollen, he has issues. If he sits, it either hurts or he immediately feels like wiggling his aft to rub his sensitive balls on the floor. When he walks, if his tail brushes against them, he immediately gets a ping to unlatch his panels

Worst of all, when they're like that, he can't even hide them in his root mode. Usually they fit behind his panels. Barely. But when they're all fat and swollen, he can't force them in there. It would hurt and he would also be creaming his panels constantly. If he's in heat, he simply cannot be out of his armour or he will have to walk around with his cute round balls on display

Anyway he should be so embarrassed about this but also someone should kiss his balls from behind and he should gasp and whine and immediately cant his tail to the side to expose his valve cos that drives him insane

His favorite activity after the cons get back from a long shift is shoving his face in each of their balls and licking the sweat off. He also loves the feeling of the big, heavy sacs repeatedly slapping into his node when they fuck him!

I think he also just likes to play with them too. Whenever he gets fidgety, his hands feel too empty or he just needs to focus on something he calls one of the structies over and they pop their panels so that he can use their balls as a stress toy. His favourite pair is long haul’s, who has the biggest, and some nights he even uses them as a pillow.

I can definitely see Sunstreaker getting these, but I also think it would be funny if it were Impactor or Iron Hide; big masculine bots thinking their balls make them look tough, only for their teammates to constantly smack and play with their balls till their crying and leaking. Maybe they thought it would amplify what they lacked in spike length/girth but it just made them look softer

Picturing that bastard picking up bumblebee in one hand while he moves the jockstrap to the side before using him as a fuckin sweat rag. Wiping his nasty balls all over him while complaining about the heat before tossing him to the side like nothing happened like a asshole while snapping his jockstrap back into place.

Bumblebee is either traumatized or doing everything in his power to get that thing to huff how nasty it is whenever he wants

Maybe he tries it one day and Heatwave feels it on the seat

He gets called into an emergency while his nuts are full and he just has to waddle around and pretend that everything is normal (Heatwave absolutely makes fun of him for it)

(Side note, out of the bots, who do you think would be into that for themselves if they had balls? I’m thinking maybe Blades)
