About a little over a month and a half after Aquaformer had sparked but before any of the other sparked bots had reached the point of sparking, Lancex was resting on the Prime's berth. He had moved in there as there were no other rooms for him, besides, Prime would likely soon be his mate. But this day, as Lancex read a book, he found his body heating up and each touch he put on his own body felt super sensitive. Lancex had experienced heat before, but never like this. But then he never had potential mates before. And before the sniper knew it, he was laying on his back, groin plating open and his partially stiff spike and dripping port showing. He couldn't help but rub on his skin as it felt so good.
Cosmos, having been on his way to the berth room was the first to smell the powerful hormones, especially as his own senses wee heightened as well. Cosmos made his way in and saw Lancex laying there, exposed and ready to go. Cosmos wanted to be sparked, but Lancex's systems were even powerful enough to make Cosmos want to take the bot. Cosmos soon walked up and startled the bot, who tried to cover up. But Cosmos stopped that and began to stroke the exposed, heated metal to make sure it ready for more.
Then, once Cosmos was sure things were ready, he climbed up on Lancex. "well, well, well. Looks like we have a horny, needy submissive bot who desperately needs a good fragging" Cosmos whispered into Lancex's more sensitive audio, causing the bot to moan. Cosmos then opened his own groin plating, and in a bit of a shocking move, Cosmos positioned himself over Lancex's spike and then slid on to it. Lancex couldn't believe the pleasure but dared not move to much as Cosmos was smaller than him. Cosmos began riding the bot.
And as Cosmos rode Lancex, Optimus and Grimlock, the next to smell the hormones, headed back to the room. They hoped their systems were right as this meant their other mates were not only ready to full bond but both also were ready to be sparked. They headed towards the room, their own groin platings moving aside as they headed back. They could only hope this went where they thought it would.
