Disclaimer: I do not own Transformers, they are owned by Hasbro. More of my depraved story picking on Sentinel Prime, as I think he has something stuck up "where the sun don't shine". This has slash and M preg. You are warned. No like – no read. This is strictly a fan fic. No flames or harsh comments. Constructive criticism welcome. Enjoy!
1 month after Sentinel Prime was kidnapped and "dealt with"
Sentinel was not feeling like himself. He continued to throw up in the morning and he kept finding himself hornier and hornier until he could no longer take it and had to self-interface, which was something he had never tried before, however, he was unable to overload unless he had something up his aft, as he had his most sensitive wring back there (unlike most mechs who had their most sensitive wiring in the front interfacing port). Sentinel was now also drinking more energon than he had, but he just figured that because he was working more than usual, he needed more energon. And since most of the bots wanted nothing to do with the stuck up Prime, most of them missed the signs that sentinel showed. The only one who did not miss the signs was Ratchet, but he said nothing as it was obvious that Sentinel wanted nothing to do with the old warbot medic.
Jazz and Prowl, being sparkmates, were asleep in their berth when they were disturbed by a very disturbing site. Sentinel Prime was, as the humans called it, "sleep walking." Jazz and Prowl, embraced tightly in each other's arms, watched carefully as Sentinel came closer and closer to the pair. Something was off with the big blue dolt, but Prowl and Jazz were trapped as the sleep walking mech had locked the door and was too big to get around. To their surprise, sentinel ignored them but went toward a drawer where the two kept certain "private" toys. Jazz and Prowl were in shock as they watched sentinel pull out a long "toy" and then quickly stuck it up his aft, and started moaning lustfully.
The two sparkmates just looked at each other in shock as they listened to the horny bot try to self interface, not realizing where he was. Unfortunately, for Jazz and Prowl, hearing the lustful cries from Sentinel began to turn the two sparkmates on. Jazz began to rub Prowl's tiny waist, just above the bots interfacing area, causing Prowl to mewl softly into Jazz's mouth. Jazz, very horny from hearing the moans, fed his hardened cable right into Prowl's interfacing port.
The two sparkmates, were so turned on that they decided to spark merge, forgetting their promise to hold off on creating sparklings until the renegade Decepticons were gone. And while the two sparkmates were interfacing, Sentinel came over, still sleep walking, and asked Prowl to help the "toy" get Sentinel off. Prowl, still thinking more clearly than the other two, managed to capture Sentinel during his whole episode, so he could use it as blackmail later as Prowl knew Sentinel hated him. Prowl, horny from the attention from his sparkmate as well as getting ready to spark merge roughly pushed and pulled the toy out of Sentinel's aft. And as Jazz and Prowl's sparks merged, getting the motorcycle pregnant with twins, Prowl and Jazz overloaded, Jazz into Prowl and Prowl onto Jazz's legs. And as the two overloaded, Prowl shoved the 'toy' roughly into Sentinel's aft, causing the top heavy bot to overload.
After overloading, Sentinel left the room, never realizing what he had done. Prowl and Jazz watched drearily as Sentinel left. After the plow left, Jazz and Prowl curled into each other's arms, neither realizing that prowl was now carrying life within his slender frame. Neither wanted to talk about what they had seen with sentinel, and so they filed the memory away, hoping that it would never be needed, but there in case. The two sparkmates fell into recharge, hoping that this whole thing was just a dream, but in a few months, everyone would realize that this was no dream, as Ratchet was beginning to realize that something was definitely not right with Sentinel and, soon, Prowl.
