Serena POV.
"Damn succubus, wasting my time," GLaDOS growled between kisses, then pulled away and growled. Because of the height difference, I had lifted GLaDOS with ease, so when she stepped back, she ended up floating slightly. Her two tails twitched rapidly before she ripped my clothes off. "I just have to make you orgasm, right? " GLaDOS said, closing her eyes slightly.
I raised an amused eyebrow before snapping my fingers, and creating a bed behind us. I sat on the edge and looked at her expectantly.
"Do you think you can do it? What were you planning? " I asked playfully. GLaDOS just snorted.
"I find it... offensive that you would even doubt my abilities." GLaDOS growled with a snort. I chuckled under my breath.
"Even when it comes to sex?" I asked playfully. GLaDOS rolled her eyes.
"For a sentient being to reach orgasm is simply a physiological response to a certain amount of stimulation in its pleasure centers. I'm more than capable of doing it." GLaDOS said dryly. I chuckled.
"Hmm, I suppose you could, after all, you've been spying on us constantly." I said playfully. GLaDOS's eye twitched slightly.
"I was just collecting data," she said simply. I smirked broadly.
"If that's what we call casual voyeurism. Okay." I said playfully. GLaDOS glared at me.
"Shut up and lie down already." GLaDOS growled, pushing me onto the bed. I laughed as I slid down. GLaDOS just stared at me, examining my body as if it were a math problem or something she was trying to solve. Finally, she floated down and sat beside me on her feet.
I watched curiously as her two tails, used to absorb magic, extended and reached for my body. They both positioned themselves over my nipples and began to vibrate. I hummed along as I sighed in pleasure.
GLaDOS's tails moved around my chest, squeezing it lightly as the vibrating tips continued to move and rotate around my hardened nipple. It was… faint, but I could begin to feel the pattern in GLaDOS's movements. It was all so… clinical and calculated, yet I couldn't deny I was enjoying the experience.
Especially when GLaDOS's tails detached and crawled down my stomach, stopping over my belly. They lightly pressed their vibrating tips against my uterus, making me sigh tremulously with pleasure.
Finally, both tails descended onto my pussy. The tips began to slowly explore my labia, and I moaned with pleasure. One of them slowly began to play with the entrance of my pussy, lubricating itself with my juices before entering. No… it wasn't the thickest object that had ever entered my pussy, so it felt strange, especially when it began to move and snake inside me as the vibrating tip began to stimulate every nerve ending within my pussy.
Meanwhile, the second one continued to play with my lips and clitoris with the same skill. Both tails worked in unison to maximize my pleasure. I gritted my teeth as my back arched.
GLaDOS's tail seemed to go deeper and deeper into my pussy, curving, bending, and moving inside, precisely hitting every part of me as it slowly moved. I could feel the slight pressure of being filled more and more inside my pussy.
Finally, I let myself go and came from the pleasure. I closed my eyes in ecstasy before catching my breath. Finally, I looked at GLaDOS, who had a smug smile. I chuckled.
"Just one?" I challenged GLaDOS. GLaDOS merely narrowed her eyes before her tails twitched once more. "You'll just... use... your tails?" I asked between moans. GLaDOS just grunted.
"My fingers serve a purpose beyond satisfying a repressed succubus," GLaDOS said dryly. I would have laughed if I hadn't half-heartedly felt the tip of her tail inside my pussy hit my G-spot.
GLaDOS continued playing with my pussy using only her tails for several minutes, and I had no complaints. Was it weird? Not as weird as creating magic penises, really. So I just enjoyed the ride. Especially because, despite how clinical and calculated it all seemed, I was actually enjoying it.
I moaned with pleasure once more before sighing with delight. Once I recovered, I gently grasped GLaDOS's tails and pulled them away.
"Are you finally satisfied?" GLaDOS asked easily. I laughed slightly.
"Oh no, no, no, no," I laughed as I sat up, pushing GLaDOS down. GLaDOS was below me, squinting. "Your voyeuristic acts must have shown you that I'm not satisfied unless I return some orgasms. I love giving pleasure to my partners," I said huskily. GLaDOS just stared at me.
"It's data collection, not voyeurism," GLaDOS said simply. I chuckled and then looked at her.
"So, how do you like to do it?" I simply asked. GLaDOS just looked at me like I was stupid.
"I don't do that," GLaDOS said, as if it were obvious. I looked at her, confused.
"You've never touched yourself?" I asked incredulously. "Are you a virgin?" GLaDOS looked at me with disgust.
"First, virginity is a human construct, both physical and social, determined by a thin membrane that I definitely don't have, and this is also my main chassis, not a real body. Only someone with some kind of fetish would think about sleeping with a piece of metal and a synthetic vagina, and the first thing they'd think is whether it's a virgin or not," GLaDOS said dryly. I burst out laughing.
"When it is a pussy as sexy as yours? Not my fault." I said with a crooked smile. GLaDOS just snorted.
"Yes, it is. It's your fault you're a horny succubus who can't control yourself," GLaDOS said, rolling her eyes. "And besides, why would I?" she asked, grimacing. "I have no need or interest in that part. It's only there because of you," GLaDOS said dryly. I just raised an eyebrow.
"And even if that were the case, I'm surprised you haven't experimented with them," I said to GLaDOS playfully. GLaDOS just snorted.
"I don't need to experiment on them. I know everything I need to know." GLaDOS snorted. "I know every nerve ending inside them; I don't need to know anything else." GLaDOS growled. I chuckled.
"Isn't it the same as the SV Aperture P-1?" I asked playfully. "If you already know your calculations are correct, is it necessary to prove it?" I asked mockingly. GLaDOS stopped before she could growl.
"It's different," GLaDOS said, blushing slightly. I chuckled before leaning in and kissing her again. GLaDOS didn't resist, though she barely made any effort to return the kiss. Less out of indifference, more out of not knowing how to reciprocate. I chuckled and pulled away.
"So, tell me... what if we do some experiments?" I said hoarsely, looking at GLaDOS. GLaDOS stopped and glared at me.
"Don't you dare," GLaDOS said through gritted teeth. I laughed almost sadistically.
"Experiment one. Let's see how fast I can make you orgasm," I said to GLaDOS as I ran my teeth along her fake skin. GLaDOS grunted in annoyance but made no effort to stop me; instead, I sensed a twinge of excitement and interest from her.
I leaned down, and my tongue immediately found its way to her small, tiny breast. I circled her nipple with my tongue, eliciting a moan from GLaDOS that sounded more like a small squeal of surprise. GLaDOS's hands gripped my shoulders tightly as I began to eagerly kiss, suck, and lick one of her nipples.
The synthetic skin, or whatever GLaDOS's skin was made of, felt exactly the same, though it didn't taste the same. Her skin tasted almost sterile and completely clean, unlike the slight natural skin flavor of the others, but it wasn't a problem.
I continued treating GLaDOS gently. My hand closed over the small cluster that was her other breast, and I began to play with her nipple. My fingers moved easily, alternating between stroking, pushing, pinching, and tugging as I tried to gauge GLaDOS's reactions.
Her body, however much it resembled that of a person, wasn't human, so her reactions and sensations were different, and I had to get used to reading her body language. Luckily, GLaDOS seemed to have no defense against sexual provocations. She was being overly vocal and physical in response to every stimulus, which definitely made my job easier.
Finally, I released her breast and lowered my hand to her crotch. My fingers lightly grazed her vulva, causing GLaDOS to arch her back. She was completely wet, more than I expected. My fingers pressed against her small, soft, and tight vulva, and I slowly began to trace the lips of her vulva.
Finally, my fingers fell upon her clitoris, and I pressed it lightly. That elicited a deep moan from GLaDOS as she came for the first time. I gazed at her, fascinated, as I felt GLaDOS's thoughts completely cease for the first time, and I smiled broadly.
I continued stimulating her pussy while she continued her orgasm and whispered in her ear.
"6 minutes and 23 seconds, experiment complete." I told GLaDOS hoarsely. GLaDOS only moaned louder as her pleasure center rewarded her with another wave of pleasure at the same time as it stimulated her clitoris, and the second orgasm was ripped from her body.
I stared at her, fascinated, as a smile spread across my face while GLaDOS finally collapsed onto the bed.
"Second test. Let's see if you can last longer or shorter with my tongue in your pussy." I said to GLaDOS huskily. GLaDOS was barely recovering and tried to grunt a response. I just went down and planted my face on her wet pussy.
The smell was… it wasn't bad, but it definitely wasn't what I was used to. It smelled similar, but my sense of smell was terribly sensitive, especially to this. Still, I took a deep sniff as I tried to memorize GLaDOS's scent.
Once she was completely satisfied, I dragged the flat part of my tongue all over her pussy, making her moan as the taste filled my mouth. I moaned with pleasure. It wasn't bad, and it was definitely artificial, but it still tasted like GLaDOS, and apparently that drove me wild too. I would definitely enjoy it.
I began to eat her pussy with great pleasure. I closed my lips over her pussy and began to move it while my tongue locked itself inside her hole. Once again, it was almost imperceptible, but I was a damn succubus; I could feel that it was fake skin, but that didn't change anything. I continued devouring her pussy while I began to memorize every one of GLaDOS's pleasure points.
GLaDOS's hands gripped my hair, though without real strength, as her body began to writhe with pleasure and she moaned. Finally, my ministrations paid off as I brought GLaDOS to another orgasm. I used my fingers to continue stimulating her before pulling away slightly, my face still wet from GLaDOS's fireworks, and I lightly licked my lips.
"4 minutes and 57 seconds. Experiment complete." Just like before, GLaDOS's pleasure center activated, causing her to moan loudly. I sucked hard on her clit as I brought GLaDOS to orgasm once more. I chuckled as GLaDOS's hands closed tightly around my hair, her mind going blank. Finally, I gave her pussy one last kiss and pulled away before pausing to look down. "Wow, you've got a cute asshole," I said huskily. GLaDOS only mumbled slightly before registering what I said.
"D-don't you dare." GLaDOS tried to say, almost panicking. I smiled slightly, my finger slowly trailing over her asshole and circling her several times. GLaDOS moaned as she writhed.
"I didn't know you had one," I said, genuinely curious, as I played with GLaDOS's hole. GLaDOS just moaned.
"It's your fault!" GLaDOS exclaimed with pleasure. "T-this body came like this!" she squealed with pleasure. I smiled slightly.
"Ooh... so... it really doesn't have any 'functional' use, and it's just for pleasure, just like your pussy?" I asked GLaDOS, my smile widening. GLaDOS's body tried to stop.
"No-" I cut off GLaDOS's protest as I ran my tongue over her anus without hesitation. My eyes gleamed slightly. Interesting, this really did have more pleasure nerve endings than it should.
"Next experiment. Will you be able to orgasm by stimulating only your cute, tight asshole? " I said mentally. GLaDOS didn't answer; she just kept moaning loudly. I smiled even though my tongue was hanging out of my mouth as I hungrily licked her tight hole.
Her hole resisted slightly, so I pushed harder with my tongue until it finally gave way. I felt the warmth of the hole and began exploring it completely with my tongue. Once I was familiar with her ass, I didn't hesitate to attack all her sensitive spots, and she had plenty.
GLaDOS began writhing with pleasure, and I had to grip her hips tightly to keep her from moving. I even heard her reciting numbers in her mind. Or at least, trying to. My eyes flashed with defiance before I began using Parseltongue.
GLaDOS's thoughts stopped as I elicited a loud moan from her. My tongue vibrated inside her asshole as I pressed on all the spots that drove GLaDOS wild, even magically stretching my tongue to reach all the most hidden corners of her ass.
GLaDOS simply moaned uncontrollably before finally reaching orgasm. Even so, I didn't stop. With great pleasure, I continued stimulating her.
"Experiment complete," I told GLaDOS, and her body arched forcefully. "Can you come twice in a row?" I asked huskily. GLaDOS didn't even take more than a few seconds to come. My eyes flashed. "Experiment complete. How about a third time in a row? " I asked mentally as GLaDOS was once again stimulated in her pleasure center.
I could feel the inside of her ass starting to heat up, and I could even feel her body beginning to work faster and faster. Even so, I didn't stop. Once she had an orgasm, I started adding another and another and another. I even began stimulating her pussy and clit with my fingers to maximize her pleasure.
GLaDOS kept having orgasm after orgasm after orgasm, stimulated by my tongue and the reward center that sent euphoria and pleasure throughout her body. Her body was burning as I brought her to another orgasm—the seventeenth. I was about to add the eighteenth.
"Stop-" GLaDOS finally seemed to reach her limit, and I could hear her entire body freeze, going completely limp. I finally stopped and stepped back.
My chin was dripping wet. So I looked cautiously at GLaDOS, used my fingers to wipe away the wetness, and then brought it to my mouth to taste.
After a few moments, GLaDOS shuddered, and her eyes opened.
"GLaDOS v7.36 is Online \\ Hello." GLaDOS's body said before her eyes blinked without focusing on anything, although she seemed completely fine, even though her thoughts seemed somewhat confused.
"GLaDOS, are you okay?" I asked with a shit-eating grin. GLaDOS focused on me, then blinked a few times.
"No," she said immediately, sounding half in denial and almost horrified. "That didn't happen," GLaDOS said through gritted teeth. I laughed.
"Oh, I'll pass, and I won't let you forget it." I said petulantly. GLaDOS glared at me and tried to attack me with her tails. Although they seemed to move clumsily. And that only made GLaDOS glare at me even more.
"Shut up and help me up. We have a ship to assemble." GLaDOS said, looking away. I laughed hoarsely.
"Oh, GLaDOS... you said you'd satisfy me. This... this was just the appetizer." I said hoarsely to GLaDOS. GLaDOS froze in place and stared at me in horror.
"I think... I've made a miscalculation," GLaDOS said, almost panicking. I laughed, then grabbed GLaDOS's leg and slung it over my shoulder. GLaDOS was sorely mistaken if I didn't seize this opportunity to devour her completely.
The flight to Wolf 1061 would have taken less time.
