I reviewed my carefully hidden files. Amy overloading, her gorgeous form trembling and teeming with moisture. She directly looked at me, yearning in her gaze. She needed me...



...



I needed other avenues to occupy my time or I would be incapable of functioning. When Amy was not around, I continued my normal duties such as surveillance, then when I wasn't expected anywhere, I tended to my garden and practiced cooking. Though I operated at the same efficiency as before, I felt... distracted.



I reviewed all my secret footage of Amy once again while checking over my garden. Beautiful... She was soft. I liked how her form changed in my hands. Her chest malleable, her hips plush. She had strong muscles underneath, each of which I made her lose control of.



...



I loved Amy and I enjoyed playing with her... but why did I feel so... hungry? Why did I want to do more? I couldn't be intimate with her in the exact way an organic person could. There was no physical pleasure I got from her other than our exchanged kisses, yet I craved it from her. More. I could only think, more.



I hoped she would visit again so I could better understand. I reviewed the footage... I watched her overload again and again. Not only was the sight alluring, but her sounds. Only I could hear them. Her cries of pleasure were for me.



...! An internal alert went off. Someone was trying to enter the base and failed.



I went to the entrance... then heard a familiar whine on the other side. I was about to open the door myself, but then it slid open.



Amy's gaze met mine once more and she gave me a bashful grin. "Hey...! I was trying to use your new door codes by memory, uh... Still getting there!" She waved a small note in her hand, then folded it and put it in one of her pockets. She eagerly jumped against me and wrapped her arms over my shoulders. "Metal~!"



I held her in return. Warm... We greeted one another with a kiss. "Hello, Rosy." I swept her into my arms and walked her inside, then closed the door behind us.



She lightly swung her legs, then kissed me again. "I like visiting your base more often! It's such a nice change of pace. You made quite a few changes here, haven't you?"



"Yes... It's much more habitable for you now. How long will you stay today, Rosy?"



"Mm... That depends...~" She gently kissed the side of my head. "How long do you want me here?"



"Forever."



She giggled, then gently nuzzled her head against me. "I'll be here for slightly less than that."



"Acceptable." I put her down after a little while, then walked down the hall with her. She grasped my hand with hers. I enjoyed that she still wanted to be close...



...



"Rosy, I want to have a discussion," I said, averting my eyes.



"Hmm? What's up?"



"Like we established the first time we engaged in intimacy that caused you to overload, I thought of our actions constantly. Every time after that, I reviewed them and reviewed them again. I want to better understand why our togetherness has such an effect on me."



When I looked at her, her temperature increased and was incredibly visible on her face. Cute...



She briefly looked away. "Um...!" She released a bashful smile. My desire for her already increased. Unfortunately, I found it an inappropriate time to act. She continued: "Since we've fooled around a few times, maybe we should talk about, like... turn-ons and turn-offs? And a few other things... I've been thinking about it, too."



"Turn-ons and turn-offs...?"



"Basically, turn-ons are things that make you more excited sexually, while turn-offs kill your mood. The more we're together, the more we'll learn, I think... B-but I think it's important to talk about our feelings as we learn. So... I'm glad you want to talk, too," she said, her smile softening.



We settled in the master bedroom and sat with each other on the bed. Amy's shoes were off while she sat cross-legged across from me. I copied her pose and patiently watched her; she pressed her palms to mine and laced our fingers together.



"Well, so far things have been really nice..."



The way she said 'so far' implied it wouldn't always be nice. I squinted at her.



"There's no 'but'!" she exclaimed. "Let's just... Talk about things we like with full honesty, then maybe that'll help get to the bottom of why it affects you... uh... us, honestly. Easier for you than me, probably," she mumbled, her face reddening.



"I wouldn't necessarily say it's easy for me. I don't really know what I like when I actually try to think about it..."



"I'll... I'll start. I've said some of this already, so..." She slightly shifted her position. "I like the way you gently touch me. I, uh... I really like when you trace your claws down me. I mean... I really like when you hold me tightly, too. So..." She looked away, blushing more. "I guess what I mean is... I like how you admire me, maybe?"



I thought for a moment. "Are you always aroused, then?"



"No! What makes you think I am?!"



"Since I always admire you," I said with a nod.



She blushed more. "A-always...! I meant, like, physical admiring!"



"Fine, then. I think I understand." With her example on mind, I tried to think of what incited similar feelings within me... I certainly loved touching her. "I like the way you react when I touch you. I enjoy the sounds you make, especially when they are of surprise or pleasure."



"Ugh... I am way too noisy," she mumbled.



I was amused. "Your sounds are cute. I like that I coerce them out of you."



A brief silence filled the space between us. She shyly shrunk her posture. "... I like when you're bossy," she muttered. "It's hot, the way you're so firm. It's so embarrassing, but I can't stop thinking about when you told me to take off my clothes."



Her words made me excited. "I enjoy you fighting back just as much, Rosy. I am satisfied when you eventually give in to the pleasure I bring you."



"... My favorite is... y-you... bullying me. When you stop stimulating me and then get back to it, my climax afterwards is so much stronger... But don't do it constantly just because you know!" she yelled.



Very amused. "That's my favorite as well."



"Maybe I'll say things that are the opposite of how I'm feeling, but..." She slightly shifted. I could tell our conversation aroused her. I wanted to do something about it. "I think that's the main thing I wanted to talk about. There's something called a 'safe word' that either one of us can use. The idea is that I could tell you to quit it, but I don't actually want you to because it's part of the... you know..." She let go of one of my hands and shyly gestured between us. "The game of you bullying and me fighting back. Sometimes I might be feeling overwhelmed but I want you to keep going. If I use the safe word, I want you to actually stop."



"Okay. What is the safe word?" I asked.



"Well, we make one up. It should be a word we wouldn't normally use during sex," she explained.



"Should it be an undesirable word, then?"



"Yeah, it can be."



I knew exactly which word would be appropriate. "Sonic."



"W-w-we are not using that!" she stammered. "And it's part of your name!"



"You should only say it if following the word 'Metal'. I would find it appalling otherwise."



"That's a bad safe word!" Amy slightly nudged my head. "And the goal isn't necessarily to turn each other off. It's just... to pause and reset. When either one of us uses it, we stop, no questions asked."



I thought for a moment... "Have I caused you harm before?" I asked.



"No!" she quickly replied. "You're careful and you listen to me. Like... Maybe I'll never use the safe word, but it's good to have one so there's no doubts to how I'm really feeling. And... I don't know, maybe there will be a situation I want you to do something you don't want to do while we're, uh... in the zone. That's when you'd say the word."



I wasn't sure there would ever be a situation I'd want to stop, but I respected the idea. She cared about me as well.



"How about something random, like... Race car!" She proudly grinned at me.



"A profoundly neutral word," I hummed in thought. "But what if there is a scenario in which you praise me for my incredible speed and force?"



Amy laughed, blushing more. "Do you want me to compare you to a race car?"



I averted my eyes. "No, I am better than every car."



"Maybe a random material or something, then. Obsidian?"



"What if--"



"I'm not comparing you to a rock!" Amy yelled.



"Fine, I will accept 'obsidian' as this safe word. But I think any subject could be brought up when we're together," I mumbled back.



"There's non-verbal safe words, too. We could use both. Umm, so let's have 'obsidian', and then..." She tapped my side. "We could tap each other like this, maybe? It would be helpful too if neither of us could talk."



I copied her movement and tapped her in return. She smiled at me; I heard her tail gently pat the bed. Cute...



"Yeah, like that. Do you think that's good?" she asked.



"I accept," I said with a nod. "I can do whatever I want to you then, so long as you do not use the safe words?"



The rate in which her face changed shade was phenomenal. "I-I mean... Yeah... Like, uh... Like what? What do you wanna do?"



I tilted my head, watching her. "I'm still figuring that out."



"... Well..." She smiled to herself, back to her shy demeanor. "Could you tell me in plain words what made you overload before? When you let out all that steam last time."



We were choosing to be vulnerable, yet I still had difficulty expressing my thoughts fully. I thought for a while on what exactly I wanted to say. "... I like to be... needed," I eventually told her. "It excites me, and... I don't know. That's what I don't understand."



Her smile softened. She slightly tightened her hand with mine, then caressed the side of my head. "I like that you're there for me when I need you." Her beautiful eyes sparkled while she looked at me. "It makes me feel whole."



Whole? Was wholeness what I received and craved?



"It's like... a part of me was missing before we were together. And when we're closer, there are moments that have me realize that. That's how I make sense of it," she explained.



I moved closer. She had the same idea, uncrossing her legs so that we could be against each other. She folded her legs over me instead, her torso pressed to mine. She rested her hands on the top of my back spine and leaned her head against me.



I was completely captured by her. It was impossible to think of anything else. More...



"... Do you need me right now?" I asked.



I felt a small, pleasant shock; she softly kissed my muzzle. "Yes..."



I pressed against her and moved her back onto the bed.



"W-wait!" she stammered, her face a bright red.



"What?"



"... There's... another, uh, tool. It's a little, um... I wanted to establish a safe word first because it's a bit... deeper... than the one we last used." She averted her eyes. "I left it here... Should be in one of the nightstands?"



I did like using the other tool on her. I was open to trying more. She unraveled her legs around me so that I could move to check the nightstands. Like she said, there was another tool alongside the pink one I used on her last time. This one was elongated, also silicone, a blue, black, and yellow... I didn't detect any kind of motor in this one. The shape was similar to available data about male anatomy, though there was nothing that matched the ridges on it... or the pattern of colors. "You want me to use this on you?" I asked just to confirm.



"Y-yeah... Uh... Maybe use your hands first, though."



I was happy she wanted me to use my hands, though I was confused. "Why?" I asked.



"T-to... to lubricate me," she muttered. "It'll hurt if you just stick it up there dry."



"Oh." I believed I understood. I did learn her own anatomy was incredibly sensitive. I trusted she would use our newly established 'safe word' if I caused her any harm, though I would still be careful. I approached her again and put the unused tool beside her. Instead, I drank in the sight of her beautiful form once more. I felt the side of her face and leaned in to kiss her. "... I'm confused, though," I said.



"About what?"



"You are not dry."



"Sh-shut up! I am!"



She was lying; I could tell from a simple scan. She could never hide her body's responses to me... It made me feel good. I reached under her dress and slid her underwear down her hips. "Your definition of dry I would consider flawed, then," I said.



She slightly shifted her hips and feverishly looked away from me. I brought one of my hands to her crotch and remembered well how to move my claws to get her to react. Her ears perked straight up as soon as I touched her, blush deepening. I could feel her heat.



"I'm similarly interested in what you consider 'wet'. I'll find out."



"Metal...!" Her response was a mix of a plea and a whine. I liked it.



I leaned over her and balanced myself with one of my arms while I felt her insides with my other hand. She squirmed under me. Delightful. She clung to my shoulders and kissed me again. Her eyes were full of hope that I would satisfy her desires. She had no cause for worry.



"Y-you... You really get pleasure from doing this?" she asked.



"I do. Very much so."



"Is... So... When you overload, is that, like... Oooh..." She interrupted herself with a small moan; her lower body shuddered. Very delightful. "... Like an orgasm?" she breathed out the end of her sentence.



"I don't have much data to compare. For me, my senses are completely overridden and I lose the ability to think for a short time."



She laughed a little. "Sounds kinda like an orgasm... Does it feel physically good? Like... You want it to happen again?"



"In a way," I replied. "I don't necessarily like losing control. But... I don't mind being in this state with you." I moved the position of my claws and continued to rub against her. I went faster, gave her a fraction of my speed. She grabbed my head and kissed me again, letting out a soft moan against my muzzle.



"It's definitely cute watching you overload," Amy muttered right as her lips parted from me. She kissed again, her tongue rubbing against my muzzle. I felt a greater shock... I felt good. Better.



I wanted to overload her first. I ramped up my movements until she moaned more than she could speak. She threw her head back, brows arched, panting and squeezing her legs against my hand. She made a specific moan that told me she was about to go over her limit. She bit her bottom lip and excitedly moved her hips with my hand in hopes of gathering more friction.



I took my claws out.



"Nooo...! Come back!" she whined. "I was almost... Guh...!"



"I know," I mused. "I think you're wet now." I took the tool she desired before. "... I can't help but notice these colors are similar to mine."



"Just... Just use it," she mumbled, averting her eyes.



I fully pulled her underwear off and held one of her legs. I took another moment to admire her body. She harbored insurmountable beauty...



I didn't yet insert the tool, instead rubbing it against the outermost part of her crotch. She experience a wave of trembling, moved her other leg to better expose herself. I rubbed further against her entrance, then--



"O-oh! Ooh!" Amy yelped when I put it inside her. She tightly shut her eyes. "Sl-slow! Slow...!"



I very slowly moved the tool deeper into her body; she clenched her teeth. I honestly wasn't sure if she was experiencing pain or not... but her cheeks were incredibly red and she hadn't yet told me to stop.



Her body stopped me from pushing the tool in more, but I knew I could be deeper... I slowly slid out instead, then moved back in. Amy let out a loud sigh, then hitched her breath again as I moved the tool in.



"Relax, my Rosy," I said to her. I leaned back over her and focused on her face. She opened her eyes... Once our gazes met, she watched me with an incredible yearning. I couldn't look away from her. Her expression... It was my favorite.



I pushed the tool in deeper and was rewarded with a new kind of moan. Her breaths puffed against me. "This is too much...!" Her voice was incredibly high.



"Do you like it?" I asked even though I knew her answer.



She responded with her most involved kiss yet. She moaned against my muzzle and tightly gripped onto my quills. I increased the rhythm of pulling the tool out and pushing it back in. The leg I held instead crossed over my lower torso. "You're really right here...!"



"Of course I am." Her statement was confusing, but she was clearly extremely aroused, so I liked anything she said.



"Faster, p-please... Faster...!"



Something about this situation overrode her desire to be difficult, but the result made her beg for my actions. Of course I complied... I moved the tool in and out at a much faster pace. Her moans became yells. She pressed herself against the bed and arched her back. She pulled me down against her, then just as quickly pushed me away. I continued to use the tool, following the sounds of her pleasure.



I increased the pace again. She got louder and louder, her breaths heavier, her movements more erratic. I wanted to see more. I craved more.



"Overload," I told her. I didn't realize I said it until after it came out.



She let out such an aroused cry that I never heard before. I moved the tool as deep as it could go, once, twice, three times--



She sucked in a gasp, and then her entire self trembled in bliss. She rolled her eyes back and her mouth dropped open. I hadn't yet seen her move so much from overloading... I treasured every single second. I would review this data a thousand times over.



I slowly moved the tool out--



"S-stay! Stay in," she panted, "please...!"



I pressed the tool in further, making her gasp again. She was still overloading.



...



I kissed her, ushering out another very desperate moan. After several seconds, she relaxed all her limbs and fully collapsed. She gave a long sigh, her gaze far-off. Eventually, she grinned, softly laughed to herself.



"Are you happy, Rosy?" I asked.



"Yeah...~" She wrapped her arms around me again and dragged me down to lay on top of her. "It was like it was yours..."



I was confused again. "My what?"



She shyly shifted. "Like... It's your dick," she muttered. "The way you were over me while you used it made me lose my mind..."



"Oh...!" She imagined that I had anatomy of my own. I wondered what it was like to actually have anatomy... I at least was thankful the tools could serve as an inferior substitute. Regardless, Amy didn't seem to mind. "Do the colors match me for that reason?"



"Maybe..." She blushed more. "I want you inside of me..."



...



...



One second she was under me, then the next second, she gave cute, breath-filled giggles while kissing my muzzle over and over. I didn't even remember her moving. I... I might have overloaded.



"Play with me more, Metal. Please..."



Fssshhhh! I had to let out steam, literally. My temperature was a dangerous level. I wasn't even sure she should touch me... But I wanted her to. I pressed against her and kissed her back. I wanted her more than anything.



"Y...You're being too compliant!" I yelled, backing away.



She giggled again. "Sometimes I can't help it... You're just so handsome, I can't pull away," she purred.



Overloading! I was still overloading! I had to stop. Stop thinking. I'd shut off.



I began moving the tool against her again in hopes she would say nothing more. She sucked in an eager breath and moved her position to better take it. Her face was doing too much to me. She looked so pleased, so happy. And then she looked at me.



I growled and turned her over. If I kept looking at her face I would go offline. She easily went with it, her tail eagerly slapping against my torso. I... I moved away and got a full vision of her lower body. The tool stuck out of her, completely slickened by her arousal. Her behavior, her complacency... It was so smug. She was not going to... to win! To defeat me!



Determined, I pressed myself against her again and vigorously moved the tool. She yelped in surprise; I knew she was fine because of the extreme lubrication. I used more powerful force, making only a few slow strokes before testing the limits of her inner anatomy.



Amy made a more desperate groan, then she began to make her high-pitched breaths that indicated she enjoyed the movements and where I put the most pressure.



"Y-you're going so hard!"



"This is a fraction of my power!" I growled again. "You have not yet known what you are dealing with!"



She laughed in between an aggravatingly cute moan. She laughed?!



I grabbed her chest and squeezed as I pressed down against her. I was pleased when she began to scream in ecstasy.



"Oh, God," she panted. "I'm already there...!"



I considered whether or not I should allow her to move past her limit so soon. "How badly do you want it?" I asked, slowing down.



"Metal...!" she whined. It was music to me.



"Say it," I said, firm.



She completely tensed, and then-- she... overloaded. She groaned out and buried her face into the bed, her lower half completely shuddering.



I thought I had a proper estimate of how much stimulation to give her before she climaxed... Apparently, my estimations needed work.



... Ridiculous! This didn't count as her victory at all! "You did not earn that reward!" I growled.



"Wh-what reward? I didn't get a reward!" Her voice was weak and high-pitched, muffled by the blankets under her.



"You overloaded before giving me what I wanted."



"No! No! I didn't!"



I moved the tool at a rapid pace again, causing her to scream. Her specific reaction was only the result of how sensitive she was after climaxing. I knew I did not make an error.



"Ohh--!! Hohhh... Hold on! Hold...!" She groaned and buried her face again.



... I continued. She desperately squirmed. I noticed her excitement increased already.



Her body jerked and she shuddered again. That time, I made her overload intentionally. I was pleased, yet confused at how it happened before.



... I wanted to keep playing with her. I moved the tool again--



"O-okay! Okay! Okay!" she panted. "I came! You happy?!"



"How many times?" I asked, temporarily stopping my movements.



"... Once..."



"You truly believe you can lie to me, Rosy?" I huffed. "And continue to deny me your honesty?"



"Hohh, I'm gonna pass out," she sighed quietly under her breath. "I'm like a million degrees..."



I checked her temperature. She was heated, but she was fine. If anything, I wanted to make her temperature increase... So I would. I continued moving the tool against her, this time slowly. "Then I'll keep going until you do," I growled. "I will consider that a proper punishment for your insolence."



"U-until I pass out?!"



I answered her by pushing the tool with more force. She groaned out; I vigorously moved against her and studied which rhythms made her the loudest. It took longer this time for her to climax; she was getting tired and she already expelled so much of her excitement. Yet, she eagerly grinded her body against me; I got the courage to look at her face again and her eyes showed the very yearning I sought for.



I turned her over again; she had a completely dazed grin on her face, her tail wagged nonstop and she took slow, deep breaths.



... I took the tool out of her.



"Oh, man..." Amy sighed out, flailing her hand towards her face.



I gently pulled her dress off of her to give her more air. As I stared at her exposed body, I felt the overwhelming desire to do... everything. Yet, what we had done... it did satisfy me. I took the time to feel her body with my hands. I enjoyed her soft form...



She let out a quiet moan and pecked my muzzle with her lips. I pressed against her more... I wanted to feel the shocks of her kiss again. I wanted her here with me... I wanted her again.



I brought my claws between her legs again and felt her insides one more time. I could tell she was tired, but even still, her sensitive anatomy reacted to me.



"I want you so badly," she whispered. "I can't have enough of you."



"My Rosy..." We kissed again. I had to properly reward her honesty... I went slower, stimulating her properly without rocking her body. I felt her heart rate increase against me... I treasured every part of her.



She let out a higher moan. I increased my pace. I loved how her breaths changed as she fought the incoming pleasure. I could watch her forever.



She climaxed again, not as explosive, but something I enjoyed nonetheless. She looked happy. I was satisfied... I kissed her again, and then we enjoyed a calm moment with one another.



I thought about our last actions. I had to reconsider what led to her second and premature climax.



"... Oh!" I realized.



"What?"



"You overloaded when I told you to tell me how badly you wanted to overload. My command is what caused it, then."



All the energy returned to her in an instant. "You were thinking about that?!"



"Yes, I didn't connect why in the moment. It's the bossiness you spoke of before... I wasn't aware it had such an effect that you would--"



"O-okay! We're done talking about it!" Amy stammered.



I was amused. How excited she got and how quick she was to deny it made me want to mess with her more. I leaned in and kissed her again.



I, too, was whole.
