After reading the book a bit longer, Jetfire and Optimus stopped and set the book aside, shocked at what they had learned. Optimus felt his groin plate tighten after reading the book. Optimus tried not to moan as he felt something coming on. He thanked Jetfire for the company, put the book away, and left. Jetfire, curious as to what all that was about, followed the apparently dazed prime.
Optimus soon reached his room and shut his door, though he neglected to lock it. Optimus, unaware that he had been followed, laid down on his bed, opened his groin plating, and noticed that his spike was stiff and leaking. Optimus understood then that he was entering his Own version of heat. Optimus then began to perform self service, using his hand to rub the hot, sensitive metal, all the while daydreaming of mating with Lancex and causing the bot to moan in pure pleasure.
Lost in his pleasant daydream while self pleasuring himself, Optimus failed to hear the unlocked door opening and closing. It wasn't until Optimus was about to overload that he noticed he had an audience – Jetfire. Optimus tried to cover himself and nearly panicked, as this was supposed to be a private moment. Jetfire, on the other hand, chuckled at this own friend, pushed Optimus' hand out of the way, and revealed the Prime's stiff spike. Jetfire asked if the Prime wanted some help with his heat as Jetifre teased the spike with his hand. Optimus moaned and asked Jetfire to help the needy Prime.
Jetfire smiled as he gave the Prime a handjob. As Jetfire was administering the handjob, Optimus moaned and Jetfire chuckled even more. After a bit more time, Optimus overloaded and overload hard. Thinking it was all over, Jetfire began to prepare to leave.
As Jetfire tried to leave, Optimus grabbed the shuttle by the arm, threw him on his back onto the berth, and pinned Jetfire to the berth. Jetfire, who had the wind knocked out of him, looked up at Optimus in the bot's heat state. Clouded by his heat and lust, Optimus made sure Jetfire was going nowhere. It was only then that Jetfire realized that Optimus' spike was still stiff and he gulped loudly.
Optimus, in his dominant voice, said mine and began to breed Jetfire port hard and fast, though with love as Optimus wasn't sadistic even when in heat. Jetfire moaned in pure pleasure and his spike soon emerged, stiff and dripping. After a bit more rutting, Optimus, with his final thrust, blasted his overload deep into Jetfire's port, and both moaned.
After the overload, Optimus collapsed on top of Jetfire and was soon out cold. Jetfire is shocked as well as happy that Optimus' heat is gone and wondered if they would be able to do this again, but this time with Lancex. Jetfire feels his spike harden as he thought about them doing this with Lancex. Jetfire, unable to help himself, gives himself self service and overloaded onto the berth and Optimus. Jetfire could only hope Optimus didn't freak out once he got out of the pleasure induced heat slumber, but only time would tell.
