Upon reaching the berth room, Grimlock and Optimus smiled, both stroking their own spikes as they tried to figure out just how to join in. The Optimus coughed and got both bot's attention. "It would seem we have two very needy, horny submissive bots, right Grimlock?" Optimus asked, his normal voice sounding even more commanding. Grimlock nodded. Cosmos and Lancex could only moan, as they made sure the other two enjoyed the show for now. "Now it is time to claim what is ours."
At that, Lancex overloaded deep into Cosmos, which caused Cosmos to overload himself. And while it felt good, it wasn't quite satisfying. Optimus came and lifted Cosmos off of Lancex and handed the small bot to Grimlock, sending a private comm to the dinobot to remember that Grimlock needs to make sure his powerful strength doesn't hurt the bot. Grimlock silently acknowledged the comm and began to use a finger with a claw to wet Cosmos more while Optimus prepared Lancex's port.
And once said bots were ready, both Optimus and Grimlock slid into their respective bot. Grimlock made sure he didn't go too hard, but still pounded in and out of Cosmos, who enjoyed the rhythm Grimlock set though it was a little harder than Cosmos liked. Optimus, though going in and out of Lancex hard and fast, still kept it safe and loving. Lancex was surprised at just how aware Optimus was even under the throws of intense hormones. Lancex enjoyed the loving dominance Optimus displayed, knowing full well Grimlock would pound the bot like there was no tomorrow come his time, and while it felt good at the moment, it left him a bit sore afterwards as well.
Then it was time for the switch. Optimus had an overload into Lancex before switching, while Grimlock seeded Cosmos's interior. Grimlock then plowed into Lancex without waiting or prepping, and though Lancex was enjoying this, he was glad that Optimus wasn't like this primative style as it was a bit much.
Cosmos, on the other hand, having had it a little rougher than he liked, was very happy when Optimus slid in, as even hard and fast, Optimsu kept in mind Cosmos' needs and size. Something Cosmos thoroughly appreciated, and it showed as he moaned louder as Optimus took him. They continued rutting, knowing that they needed just a bit more before the big overload came.
