Hundred Theme Challenge, using Doctor Who and Torchwood. Suppose that makes this a cross over of the two genres, but as far as I'm concerned they're in the same Canon. Neither belong to me. Please review! Of course this is going to be Mature, and mostly male on male! Please read and review!
Jack had had lovers aplenty. Green skin? Check. Gills? Check. Odd cooing noises as sole language? Check and mate. Ohhh Mate. Mate mate mate mate. Humans had become proverbial bunnies by Jacks' day. Jack was experienced. Jack knew his way around the block, the octagon, and the dodecahedron. He knew that not all 'sperm' tasted the same, that some species didn't have 'sperm' at all. He knew that certain breeds would change colour as they climaxed, that others would go through a trans-space shift and disappear, coming back into a visual dimension after calming down. Jack Harkness truly thought that he had seen it all. Hell, he'd cataloged half of it for Torchwood. "Jack, we're not sure how this reproduces, mate with it" was almost a bi-monthly assignment.
So it is really was just another day when on duty, for 'the good of the British Empire' he found himself completely entangled with all six limbs of a highly intelligent, misunderstood and quiet creature from Sector M-96. God this thing was amazing. A tentacle like phallic instrument, thick and long but not too much so, gently but relentlessly thrusting into Jacks' accustomed entrance, hitting all the right spots. All five mouths, one on the face, one on each palm, all kissing and suckling. Yes, Jack Harkness was in a form of heaven. Unfortunately, he'd been there for several hours now, and had spent every last drop of his seed. The creature's stamina was amazing, and with each shuddering climax it had, a small bag on its abdomen would empty slightly, but soon refill. Jack assumed it was an appendix of sorts, meant for holding this creatures equivalent of sperm. He was learning a lot, but damn, he was tired. As tired as an immortal could get, at least.
How many times had he accepted the aliens' goo into his gut? How many more shots could he take? He was already starting to feel cramping, bloating... this couldn't be good. Surely, if this continued, he would burst. But, for the sake of science, Jack grinned and bore it, knowing that as soon as it was over, he'd be able to clean up and be fine. And of course, if there was an emergency, he could contact Torchwood... but he'd rather not have this poor things mating rituals interrupted.... and those lips on his back and neck and cheek and lips and nipple all felt so good... it was like group sex, but less awkward, less fighting.
Ah... but way more filling. Jack took a few deep breaths, trying to let the pains in his guts calm down, starting to squirm, and pull away. "That's enough, big fella. All I can take...."
The lost traveler shook its head, pinning Jack firmly with all four arms, two legs between Jacks', thrusting all that much faster, hitting the prostate again and again and again, wanting Jack to be happy, to let it finish whatever its goal was. Jack could do nothing but moan limply, his tired, overstimulated, over sensitive member hardening and preparing to spew again. The Creature beat him to it by a few seconds, this time using one of the many hands to press on the sac, emptying it fully into the slightly less than willing immortal human.
"Fuck, that...ahn, God what the..." Jack ground his teeth in surprised agony, the skin of his torso felt tight. But there was no sloshing, no liquid dripping down his thighs. Even as the creature removed the tentacle, laying beside Jack and running fingers, three on each hand, through his hair, there was no leakage. Tears stung Jacks' eyes. "It hurts...." He whimpered, and the creature made a clicking noise, gently caressing and palm kissing the engorged belly.
"Wh-what did you do? Oh God... I'm gonna be sick...." Jack barely managed to get his head over the edge of the mattress before stomach acid and lunch pushed past his teeth and lips. The creature rubbed his back, made understanding noises, and wiped his mouth with a corner of the sheets when he was done. Jack lay back, his hands skimming the stretched tender skin. He yelped in surprise as he watched something inside press against his palm, stretching the skin even more.
"I'm pregnant?! You little bastard...." He fumbled for his comunicator, rather peeved at his cuddly bedmate. "You could've warned me, you know..."
The creature just made more clicking noises. Damned thing... "Torchwood one, this is Agent Jack, I have a situation, repeat, I have a situation."
That bitchy woman responded promptly. "Agent Jack, we hear you loud and clear, please give details as to your problem."
Jack sighed. "The damn thing knocked me up. Assistance is required."
Jack tried to ignore the laughter he could hear in the background. It was going to be a hell of an evening.
