Soundwave's stamina was unexpected, yes, though it would make sense when Jadewing was thinking clearer. Soundwave had to be able to channel significant amounts of energy to create groundbridges; of course it'd take him awhile to overload.

Whatever the case though, Soundwave clearly needed a bit of an extra push. And soon because the way the younger mech's valve was milking his spike Jadewing was unsure how long he could hold off. His own valve cycled down hard as he reached over and pulled one of Soundwave's tentacles closer. While keeping one hand on Soundwave's hip to steady them both as he fragged him at a gradually increasing pace, the other roamed over the tentacle, teasing biolights. He began to suckle and tease the nearest one with his mouth in earnest as well, scraping dentals lightly over it and only taking brief pauses for panting to cool his heated systems.
