Thankfully Soundwave had already prepared everything, because if Blitzwing was alone right now, heâd panic and lay his eggs under someoneâs bed, like a cat birthing kittens in an unsuspecting ownerâs closet.
The pregnancy (or âeggnancyâ, as Knockout had snickered about) started out easy enough. Blitzwing was a good boy and took a whole 13 eggs from Soundwaveâs tentacles. By the first month he had decided to forgo his abdominal plating, showing off the goods. He had been chastised at first but as his belly grew, he received more gaping stares than scoldings. Even Soundwave was prone to losing himself while working when Blitzwing sauntered by.
Halfway through, Blitzwing demanded sex almost constantly. Soundwave could hardly keep up. Eventually heâd grab Blitzwing with his tentacles and fuck his leaky valve while working- not that he was getting much done with such a spectacle next to him, but still, itâs the thought that counts.
Near the end, Blitzwing was like a whiny cat. He was bed bound at that point due to the eggs (or Knockout just liked seeing his new favorite patient be helpless), so he relied heavily on Soundwave. Icy whimpered for physical affection, Hothead snarled and demanded his craved food, while Random made noise just for the sake of getting his partnerâs attention.
Soundwave wasn't bothered. He enjoyed seeing his lover like this, his protomesh swollen and spilling out. The rest of Blitzwingâs body had proportioned itself as well- he abandoned his chassis piece as soon as he started staying in bed, letting his new swollen breasts hang out. Sometimes Soundwave came home to find Blitzwing leaking bright cyan energon-rich milk everywhere, his valve and spike soon following suit with cobalt lubricating oils.
They spent many nights curled up together on their shared berth, Soundwave massaging Blitzwingâs fat in any way possible. Most times, Soundwaveâs tentacles suckled Blitzwingâs breasts, his servos rubbed Blitzwingâs tummy, and his large spike plugged Blitzwingâs valve. Blitzwing was simply in pure paradise.
Now, when his water broke and his genital plating was leaking fluid, Soundwave gently carried the triplechanger to the prepared birthing nest. He grabbed each limb with a tentacle to position the eggbound mech properly. Soundwave made a reassuring chitter when Blitzwing whimpered, then slowly opened up his plating to see his heavy, leaking valve.
To their surprise, the first egg was already almost there. With a simple push, it plopped out onto the soft bedding.
Randomâs face chattered excitedly. âLook! That one would be good hard-boiled.â
Soundwave made a disapproving noise and a tentacle lightly smacked the back of his helm.
Icy spoke next. âAh⊠good thing they're not fertilizedâŠâ He grunted and pushed the second egg out, a spurt of fluid soaking his thighs.
Soundwave was unusually âtalkativeâ, making all sorts of noises to encourage Blitzwing. Even the stupidest of mechs could see that he was, indeed, actually worried- Blitzwing was in bliss now but there were many things that could go wrongâŠ
The third egg got stuck, resisting several attempts at pushing. Hothead snarled in irritation. âStupid mech! This is all your fault!â He snapped.
Soundwave wasn't bothered, knowing this was a natural reaction- apparently it was a stereotype for pregnant humans to blame their partners for the pain. But the egg soon popped out thanks to Hotheadâs passion and Blitzwing resumed whimpering in pleasure.
The next egg caused Blitzwing to moan wantonly. He couldn't take it anymore- he popped out his halfway inflated spike and began to rapidly stroke himself. He ignored Soundwaveâs annoyed huff, fondling one of his own breasts while stroking.
âIt feels so good!â he whimpered, his right optic fluttering shut before the faces changed again to Random. âOoh! I want to lay eggs in you, next, Wavy! We can sound your spike and eggs will fill up those beautiful balls of yours and-â
Soundwave silenced him with a tentacle in his mouth he could suck on. Blitzwing took it happily, still rapidly jerking himself off.
Soundwave leaned forward helped ease out the next few eggs before he bolted back, sitting on his haunches. Blitzwing had unexpectedly overloaded on his faceplate. Random was giggling at him before Icy switched back in.
âSorry, mein liebe. I believe that will be the first of many, ah, cumshots, as the humans say.â His motions continued, his spike leaking even more dark blue lubricating fluid.
Finally, after a few more of Blitzwingâs overloads and eggs, it was the final stretch. The eleventh egg was crowning when Blitzwing decided to stop pushing and massage his puffy purple valve.
Soundwave rang in annoyance, attempting to swat Blitzwingâs servo away, but Hothead growled at him.
âHold on. I want to enjoy this!â He grit his teeth and groaned, his hips sputtering. He suddenly squirted everywhere, soaking the already-dampened fabric that lay around them. He let out a high-pitched moan, surprising for the face being displayed. Pure pleasure was resounding throughout his body, through his abdomen and causing his spark to sputter in excitement.
Soundwave took pity on the triplechanger and rubbed his servo digits on Blitzwingâs node. Another spurt of squirt came out when the next egg made it out and plopped onto the wet pile.
It felt like sparks flew through Blitzwingâs body, lighting every nerve on fire. His optics widened and he shouted as the final, thirteenth egg popped out, another overload taking him. He must have had at least half a dozen orgasms by now, Soundwave already calculating how much energon heâd need to retrieve after the affair.
Blitzwing slumped into Soundwaveâs arms and tentacles. Soundwave chittered and purred for him. He massaged Blitzwingâs abdomen with a tentacle.
âArenât you horny?â Blitzwing mumbled. âI figured youâd be touching yourself, too.â
Soundwave paused. He looked down at himself and realized that his own genital plating had been leaking electric blue lubricant the entire time.
