Here's a potential scenario about the Wheeljack request last time. Imagine, there was no more war and Cybertron was rebuilt and perfectly fine with everyone living in peace and harmony having a great time with each other. And Wheeljack is hanging out with his old wrecker friends before and after the war at a bar/club (your choice) having a drink and chatting about their lives and, then the conversation changes to betting one another to do something stupid and when it was Wheeljack's turn he gets a bet to hookup with someone else at the bar/club. He was hesitant because it has been a while since he'd done it and his friends calls him either scared or that he doesn't have the guts to do it, so of course he is arrogant and egotistical so he accepts the bet and then one of his friends pointed out to Y/N that was also at the same place as them and, told Wheeljack to go hookup with Y/N as the dare and after that he gets a few cash in return. Reluctantly, he agreed to the bet and decided to man up and go up to the big ass Predacon and hit on them and, before he knows it his valve was getting wrecked with a large spike that was ramming in and out of him over and over and then he gets that sensation of the transfluid spilling inside of him.
