Primus Almighty, Spinister works fast. Brainstorm presses a hand over his mask, but it doesn't do much to muffle the sounds he grunts and whimpers out as the mech takes his node between his fingers. He wasn't aroused when he shot Spin, but heat was lacing through his circuits now as charge began to build, making his node and spike stiffen a bit more.

"Spin--!" he gasps, arching up as his spike disappears down the heli's intake, but he had no more room to thrust up. He was already fully inside, the warm squeeze of the throat rippling around his quickly hardening cord. His other hand stays on the mech's head, holding it as his spike twitches inside Spinister's intake and he tries pushing him slightly to see better.

Even without pollen to help him along, he was a messy mech. As he grows hotter and his spark pulses a bit quicker, a steady trickle of lubricant starts to dribble from the mouth of his valve. It mingles with the wetness on the floor, but then the sprinkler finally shuts off, leaving both of them and everything in the lab rather soaked.
