Walking through the evolution pit, Kerrigan's steps were quick and determined. She didn't want to think too hard about what she was doing, because if she did then she might feel ashamed. It was hard to admit that she had been thinking about doing this for a long time, and now she had finally caved to her desire for sex. With so many planets already conquered for the Swarm, life had become easy. Boredom had set in for her, and it wasn't healthy. This will be good for both of us. I need this, and he needs to feel useful. Besides, I can't lead the Swarm when I'm slowly going mad from a lack of touch, she thought to herself.
Abathur appeared, hearing Kerrigan's approach. His demeanor appeared closer to his usual self, and Kerrigan wondered why.
"New essence source detected?" he asked. Kerrigan shook her head.
"You know we own this part of the universe, now. We'll be cruising for a while before we find someplace untouched by us. Why aren't you grabbing me and shoving me inside you?" she asked.
"Discovered ability to relieve self manually. No need for assistance," he said drolly. Kerrigan crossed her arms, and leaned on one leg.
"Yeah, is that really better, though?" she asked.
"Simpler, quicker, more efficient. Less messy," he said. Kerrigan rolled her eyes.
"All right. I hear you. I get that. You don't like to rely on others. That's fine. I suppose I have something else that you want, though. You never did get to study my primordial zerg sequences," she said. The long, fanged arms on Abathur's back twitched.
"Beyond my understanding?" he asked cautiously.
"We could find out. I know how badly you want to explore this," she said. His back arms waved about in excitement, and he wasted no time slithering closer to Kerrigan, and reaching out to grab her. Using her psionic ability, she sparked his finger, causing him to quickly withdraw.
"It's a trade, Abathur. You know what you need to do for me, if you're going to get what you want," Kerrigan said. His eyes narrowed, and he interlaced his fingers under his face.
"Trade accepted," he said. He reached out quickly again, and encircled Kerrigan with his hands. Drawing her into his body, she found herself once again in his glowing green innards. It felt cool and soft, with undulating waves of movement pressing all around her. Pushing aside her reservations, she reached down and felt his wiggling member, which curled itself around her fingertips.
"New augmentation. Increased area of nerve enriched tissue. Can feel you in many different areas now," his voice boomed around her.
"Oh, yeah?" she said. Pressing her face against the tissue in front of her, she sucked the soft flesh into her mouth. The walls around her pressed in on her, and he rumbled with pleasure.
"It's everywhere now, isn't it? I thought you weren't fond of this augmentation," Kerrigan said.
"Increased nerve tissue causes faster relief. More intense, more satisfying. Less time spent feeling desire," he said.
Kinda like a vagina now, I guess, Kerrigan thought. Never thinking that she'd find herself in an alien vagina, she reminded herself that the universe was a strange place. She ran her hands against the flesh around her, and was rewarded with his pleasured rumbling. Opening her thighs, she watched the lower tentacle stroke her vulva, and then slither inside of her. It swelled inside of her, filling her completely and tightly, and pulsing in and out. He thrust inside her, and she moaned as the sensation hit her in waves that coursed though her body. Enjoying the sensation, she was in no hurry to orgasm. Turning over, she felt a renewed pleasure as he screwed her from behind.
As her hands pressed against the flesh before her, they started to burn. Around her, the glowing membrane closed in on her, and where it touched her skin it torched her nerves with pain.
"What?" she said.
"Will study while accomplishing task. More efficient. Will honor bargain," he said.
"Not exactly what I agreed to," Kerrigan said. She cried out in pain, as he probed the very depths of her DNA through his membranous tissue. The pain was at the cusp of being bearable, and there was also the intense pleasure of his artfully sliding in and out of her vagina. He'd gotten better, likely from exploring his own erotic tissue created from Kerrigan's donated Terran DNA. The tentacle swirled around inside Kerrigan, and rubbed against her rough spot with perfect rhythm. He pressed the tentacle all the way inside, and at the root he rubbed her clitoris against his inner wall. It brought her close to the edge of orgasm, without pushing her over. Her skin was alive with both pleasure and pain, and for the first time in her life she began to think that she liked pain. Small finger-like appendages grabbed Kerrigan's arms and legs, twisting them back and pulling them until her tendons stretched. The green fluid inside Abathur spread across her skin, reading her DNA sequences and leaving hot burns in their wake.
"Sequences complex, yet clean. Swarm sequences full of imperfections. Queen's sequences interlocking concisely, no wasted space, no junk. No viral sequences. No hinderances. Question how can exist in nature," Abathur purred. The tentacle swelled inside of her, as he grew more excited by Kerrigan's extraordinary nature.
"You think you can do better than eons of evolution, then?" Kerrigan breathed, her speech staccato and jolted.
"Nature is erratic, unplanned. Through randomness comes order, when survival at stake," he said. As he said this, tentacles held her chin, and ran themselves across her face. She cried out at the biting pain they caused, and struggled to escape their grasp to no avail.
"True, cannot create primordial zerg sequences. Can maybe imitate. Need more time to study, plan," Abathur said. The crawling fingers on Kerrigan's body quickened, and she began to feel the pain ramp up. She struggled to speak, as her mind set off warning signals and told her to run.
"Abathur, I'm willing to let you continue working on me, under my conditions. I can deal with this much pain, but any more is too much," Kerrigan said.
"Need to delve deeper," he said. Kerrigan paused to take some breaths.
"How about this. We take it slow. You can get a lot of information from the surface, so there's no need to rush. I'll let you delve deep once per session with me," she said.
"Pain short term, benefits of study vast," he said.
"You say that. But Terrans remember pain. It's not good for us. And, you do want to stay on my good side, don't you? Once per session, that's it," Kerrigan said, pain making her sentences short.
"Terms acceptable. Will go deeper now," he said.
It felt like ghostly fingers were pushing their way into Kerrigan's body. It was the kind of pain one felt from getting stuck with needles, sharp and electric. Kerrigan yelled, but as it continued she began to adjust to it. Her zerg body could handle pain far better than her Terran body ever could.
He didn't stop fucking her, either. As he probed her body, his member writhed and slithered more quickly inside her.
"You enjoying yourself?" she asked.
"Enjoyment greatly increased," he said.
"I think you like causing pain," she said.
"Will test theory," he responded. An invisible hand reached in and squeezed Kerrigan's heart, causing pain so intense that her vision turned to static. She wanted to cry out for him to stop, but she couldn't speak. Instead, she thrashed around and fought to escape to the exit.
"Wait!" she managed to call out.
"Make you stay?" he said. He closed in on her, and she could barely move. She endured the crushing pressure inside of her chest, while Abathur intently rubbed himself against her and inside of her. The intensity of his lust for her fed Kerrigan's dark desire for him, and she couldn't help herself. She found that she was able to orgasm, despite the pain, and maybe a little bit helped by it. The combination of Kerrigan's orgasm and the indulgence of his sadism caused him to climax with gut-wrentching intensity. He was so pacified by it, that he relaxed his insides and released Kerrigan.
She fell out onto her hands and knees, and stayed there for a moment to catch her breath. Getting up, she turned and looked at him. His green eyes stared at her intently.
"Maybe experience with you better than auto stimulation," he said.
"It better be. Maybe we can discuss using a safe word, Abathur. We probably should have done that sooner," she said.
"Never heard of 'safe word'," he said.
"I'm sure you haven't. Well, you sure have your uses," Kerrigan said.
"Abathur, most useful zerg in swarm," he said.
"I guess you are, huh?" she said.
