Tim had been forewarned. Kon laid it out in no uncertain terms - his Kryptonian genes had mingled weirdly with his human genes and even Kara had been unable to fully help him understand how the hell his body worked. But the bottom line was - his dick was prehensile and tentacle-like and he definitely had some sort of heat cycle. 

This was all fine.

The problem was that this tentacle was now worming its way into places it definitely did not belong.

"Kon! What the hell? How the hell is it doing that?" he yelled, pointing between his legs.

Panting, Kon peered over his shoulder and stopped short, eyes growing wide.

"So… I'm guessing that's not supposed to happen?"

"You think?"

"I don't know! It's my first time doing this whole 'sex' thing."

"Kon, these parts of my body aren't even connected. Your dick ripped a hole in me somewhere."

Kon contemplatively sucked air in through his teeth with a whistle, cringing. "Maybe it… phased through?"

It had started off with a pleasurable pressure at the base of his dick, then spread down the length to the tip like the world's slowest and weirdest orgasm. But just as Tim was relaxing into what he thought was oncoming bliss, something tiny and blueish poked out of the tip of his cock and wiggled around. 

The tip of Kon's prehensile alien clone dick.

And then it kept on coming, growing wider as it pushed out to stroke the underside of Tim's cock, wrapping around the base of its head. 

Tim had screamed. A little.

And now they were both staring at it without a clue as to how this could possibly happen and Kon still hadn't stopped humping him.

"Pull out. Slowly, though."

Kon moaned. "You've got to be joking. I told you I can't stop when I'm in heat."

"Fine, you can stay here and jerk off after you pull out. While I get myself to a hospital, apparently."

"Just. Just let me come. And then I'll fly you there. It'll be the same, time-wise."

Tim's next considerably more irate and panicked reply was cut off by a moan as the pressure in his dick increased and he watched it swell to be wider as the tentacle pushed more of it's length out of his urethra, growing in girth and stretching his dick around itself. He groaned in pain at the stinging in his tip, but his knees spread wider on the bedcover. Even possibly dying from som really fucked up internal injuries, he was the horniest and hardest he could ever remember being watching his dick bored out to one and a half times it's usual thickness.

"Hey, Kon! You home, buddy?"

Tim's eyes flew to the open window, where Kyle Rayner flew in feet first, landing just two feet from the bed and straightening to full height before he registered what he'd flown in on.

Still grinning and quite pleased with himself, it took Kyle several seconds for his eyes to grow wide and for him to take a step back. "Uh."

"Oh, perfect." Reaching past Tim, Kon's hand shot out and grabbed Kyle's wrist. "Kyle, you horny, buddy?"

"What do you mean, is he horny?" Tim said, not able to either back away into a humiliated corner or pull off and run away, watching as Kon manhandled a confused but not entirely resisting Kyle onto the bed with them. "Kyle, scram!"

"Uh," Kyle looked between the two of them. "Love too. Superboy's grip is no joke, though. Sure, I'm always horny, but looks like you guys have got it handled, so I'll just-"

"No, no, this is exactly what I need. Come on, Kyle, take off your pants," Kon said, already tearing through Kyle's Lantern uniform and turning him around to kneel in front of Tim.

Kyle gave Tim a look of concern and whispered loudly, "What the hell is happening right now?"

"Kon's in heat," said Tim deflating, realizing he had no contingencies for how to deal with this and never in his wildest dreams could he have come up with any for something so fucked up. "We were trying to have sex for the first time. You and I might need to go to the ER after this."

To his surprise, Kyle relaxed, grunting as Kon pulled him close enough to rub his ass against Tim's tentacle-wrapped cock. "Oh, so one of those days, huh? Bit of xeno action? Alright, I'll patch us up if it gets too crazy." He waved his right hand slightly, his white Ring catching the light and shining pearlescently. 

Kon's dick meanwhile, was unwrapping itself from Tim and feeling its way across Kyle's ass. As soon as the tip poked its way into his asshole, the rest of it surged forward, leaving Tim groaning in discomfort. He looked at his tip, which had been reamed out, his urethra now large enough to fit a whole other dick inside it, with faint traces of blood mixing in with his precome and the lubricant the tentacle was trailing after itself. His ass also felt like it was being stretched much wider than at the start, and yet nothing hurt.

"Fuck, just realized you probably secrete some analgesic."

Kon, who had been gasping into Tim's shoulder with convulsing shudders, looked up. "Huh?" Tim had never seen his eyes so glassy and vacant.

His thoughts were cut off by the warm press of Kyle's rim around the head of his dick. Tim shuddered, thrusting up into the tight heat, his way eased by the tentacle already penetrating Kyle and dripping lubricant in its wake. He looked up fearfully, looking for permission or forgiveness.

Kyle was looking back at Kon with a frown, his hips still held in Kon's grip. Their eyes met and Kyle shrugged. "Not even the most unexpected or strangest sex I've had this week. Outer space is fucking weird, man. Don't sweat it." He shifted his hip back and pressed deeper onto Tim, his lips parting over a contented sigh. Tim watched the curve of Kyle's mouth, fascinated by how much more attractive the man was up close and horny. Not like Kyle was normally lacking in good looks. 

Though he couldn't see it, Tim's dick felt like it was swollen to the size of a fist. He feared that any moment now, the horrible pain would start and it would split down the center like a sausage breaking its casing and the horrible visual only made him want to come harder.

Time seemed to dilate. He found himself caught between endless pleasure and dreams, head rolling back onto Kon's shoulder and Kyle's voice coming from somewhere far away. "Huh. Yeah, I really don't think things are meant to do that."

His dick was twitching and he could no longer tell if he was coming or even awake.

Tim shook the sleep from his eyes, propping himself up on one elbow as best as he could, still connected to both Kon and Kyle. All three of them had been lying on their side. So he must have lost consciousness after all.

Kon was out like a light. 

Kyle had his head cushioned in one arm and was idly playing with the tentacle that was peeking from his dick, curling around his fingers lazily. He looked up at Tim with sleepy eyes.

"My advice?" He paused to yawn and stretch, his ass squeezing around Tim's soft dick. "Get Bats to make you some custom condoms. You think someone's dick going in your ass and coming out your dick is weird? Don't wait to find out what getting knocked up by an alien is like."

Forget condoms.

Tim was never bottoming ever again.
