As Boulder watched Heatwave writhe in pure pleasure, Boulder stroked his own needy spike as he wondered when it would be his turn with the submissive fire engine. He dared not challenge Hightide though for now. After just a bit longer, the hand that danced around Heatwave's port stopped and he whined needily. He needn't have whined as soon his wet and slightly loosened port was feeling like it was being stretched something fierce. Hightide was sliding his thick spike into the fire truck. Hightide started a bit slow as the port was pretty tight, but soon found he was able to thrust hard and fast into the port. Heatwave moaned and mewled in pleasure, his optics seeing stars from all the pleasure.
And while Heatwave was completely pleasure shot, Hightide was at least aware enough to notice that Boulder was eagerly waiting his turn. Hightide smiled and invited Boulder to join in on the festivities. Needing no further invitation, Boulder soon comes over to join in. Hightide goes back to his fast thrusting. Heatwave moaned even as he felt a weight next to him. The stars had faded and Heatwave was able to see Boulder right next to him. And while Hightide continued thrusting, Boulder planted a deep kiss on Heatwave and began to stroke the bot's needy and lonely stiffened spike. The pleasure shot up even higher for the submissive bot. All three unaware this much pleasure could trigger the fire engine to potentially become sparked even without a spark bond, but then none seemed to care either.
Soon enough, all thee hit overload, Hightide into Heatwave, Heatwave onto Boulder's hand and Boulder onto Heatwave's back. All three feel their cooling fans kick on as they come down from their pleasure high. It takes a few minutes for any of the bots to get back to somewhat normal functioning.
Once they were cooled off, they cuddled together. "So, have long had you two had a crush on me?" Heatwave asked.
"Since the rescue bot academy, but I figured you probably weren't interested at that time" Boulder stated.
"First time I met you on earth" Hightide replied. Heatwave nodded, happy with what had occurred, still unaware his submissive protocols were active and would be for some time. The other two drew near to the fire engine and soon all three fell into a pleasant slumber. Heatwave, while sleeping, was concerned what the Burns family and the other bots would think. He could only hope that they would accept this. Only time would tell.
