“It's so... tight,” I said, carefully holding my spoon between two massive fingers.

“Mm?” Robin looked up from her own cereal on the other side of the counter. “What was that?”

“Like....” I took a spoonful of cereal and swallowed it. “I tasted that. Don't know how, but I did. And I felt how cold the milk was on my tongue. I can feel this bra,” I said, gesturing at the simple black number on my chest, “and these panties.” They were black to match the bra, and just as plain.

Robin tilted her head to the side, slurping up the last of her cereal. “Of course you can, Jen.” She was sitting down at the kitchen counter. I had to stand, for fear of splintering our poor chairs.

“But, if I pay attention....” I lifted my arms and hugged myself. “I feel the suit, too. Not just feeling with the suit. I feel the exoskeleton pressing on my body, squeezing my skin... and then the outer suit, pressing on that.” I grabbed some skin by my midriff and pulled, and with my strength it stretched a bit more than regular skin would. “And that's not even getting into the, uh, inserts,” I added, letting it snap back into place and wincing a little.

Robin frowned for a moment, and before I could think to ask why, she smiled and leaned forward. “And how does that make you feel?”

I pursed my lips. “Good.” No, that wasn't quite the right word. “Comfortable, I guess... secure? I feel safe.”

“Yeah? That's great!” Robin nodded, still leaning forward. “Honestly, that sounds like a lot of what I love about bondage.” Then she winked as obviously as possible. “Hint, hint.”

“Hmm, I guess... except that if I were tied up, I couldn't do this!” Before Robin had a chance to lean back, I reached across and grabbed her with one hand, then picked her up across the kitchen island. I hefted her over my shoulder like a duffel, laughing at her little ineffectual kicks as I carried her over to the couch.

“No fair!” She pummeled at my upper back with her fists, but feebly enough that I could tell she was only playing.

In a fluid motion I laid her out on the couch and leaned over her, our mouths close. “You couldn't stop me even if you wanted to,” I aid, smiling like a predator.

And she smiled back. “Is that a challenge?”

I leaned in and nibbled at her neck. She shivered and moaned, “S-s-so unfair.”

–

I couldn't exactly lie down on the couch, not if we still wanted to have a couch. So instead I picked it up, put it in a corner (god, imagine how easy vacuuming would be like this), and pulled off all the cushions to lay them where the couch had been.

From there, I lay on the cushions, and my girlfriend lay on me. Apparently my breasts made perfectly fine pillows for her, and I wasn't complaining. “You're warmer than I thought you'd be,” she murmured, pulling up some streaming service or another—who could keep track these days—and choosing our favorite Christmas movie. “And you're nice and soft when you're not flexing.”

I tousled her hair as Die Hard started up. I was acclimating pretty fast to the suit, and I wasn't even worried about bruising her head.

So, when you pull up a movie like Die Hard while cuddling with your girlfriend, you don't really do it to be enthralled by the gripping drama and edge-of-your-seat action. Particularly not while you're sealed inside two layers of busty blonde fucksuit. Most of the following hours were spent making out, copping many feels, and exploring each others' bodies; I felt like a humanoid playground for Robin.

Among the things I learned: nipples were very good. We'd never done much with the ones on my regular body, but maybe twenty minutes in, Robin reached over and started pinching and teasing one of mine, and I squirmed with pleasure. Not to be outdone, I reached under her panties and pushed a finger inside her, and learned something else new: my middle finger alone was enough to fill her up.

Other things: fingering my new pussy was okay, but it could take Robin's whole fist just fine, and a decent chunk of her forearm into the bargain—and that felt much better. On the other hand, when she tried surreptitiously slipping a finger into my rear, I clenched up so hard she yelped—more from surprise than anything. I mentally filed that one away under 'needs further testing'.

Before we knew it, the movie was done. Robin stood up, yawned, and stretched. “Back in a bit, I wanna check something.”

For my part, I took a bathroom break with zero difficulty—other than having to crouch over the toilet, rather than sitting on it directly, for fear of shattering the porcelain. If nothing else, it emphasized that the suit was intended for long-term use.

When I got out, I saw Robin lying on the couch cushions, reading a little pamphlet. I scooped her up without any ceremony, lay down beneath her, and placed her on my torso, and this time she didn't even react. “What's that?” I said.

As I looked over her shoulder, it quickly became clear what it was: the exoskeleton's instruction manual. I'd neglected a lot of pages, pretty much all of them past the first, so this was new to me. Apparently, the instruction manual did mention the anal probe, and recommended practicing holding things with extreme caution, and—

Robin snapped the book shut.

“Hey!” I said. I reached for it but she held it tight to her chest. “I was reading that.”

“I don't want you to read that,” she whined.

“Why? It's my suit.”

She grunted. It sounded annoyed. “What?” I said.

“First of all.” She twisted around so she was facing me. “Spoilers. If you read the whole thing, there won't be any surprises for later, and didn't you like this surprise?” She pointed a finger and booped my nose, and I flinched a little.

“And second. I thought you said you were gonna be Jen all day, so why are you acting like plain old Mark in a woman suit?”

I blinked a few times. “I... am Mark in a woman suit. How else am I supposed to be Jen?”

She stared at me for a few seconds before her expression softened. “Nevermind.”

“What? Wh-what's wrong?” I craned my neck forward to look at her.

“I was just being selfish, is all.” She just turned over and buried her head into my chest. “This is the greatest Christmas present you've ever gotten me, and I love you so much, and thank you,” she mumbled, her voice muffled. It tickled to have her breathing air into that spot, and I giggled and squirmed. “Is something the matter?” she added, looking up innocently.

“Don't you dare—” I began.

It was too late. She pressed her face back in and started motorboating me, and I shrieked like a teenager.

–

The day passed without much further event. We opened the rest of the gifts, played some video games (stopping after I pulped a controller by mistake), and had dinner by candlelight—followed by sloppy candlelight makeouts.

By the end, I was feeling pretty tired, considering how little I'd actually done all day. We'd been indoors the whole time, but spending that time in a heavy exoskeleton—even a heavy exoskeleton that did almost all the heavy lifting for you—made it a lot more draining. Finally, as Robin was getting ready for bed, I yawned, disrobed, and stuck a finger inside my vaginal opening.

“What are you doing?” she said through a mouthful of toothpaste.

“Getting out for the night,” I answered, as my fingers looked for the seam.

“Actually, one sec!”

Robin spat out her toothpaste, then took me by the hand and led me into the bedroom, where she picked up the charging cable I'd ignored earlier that day. Now that I looked at it, it was pretty odd: there were prongs to go into a wall socket, but the other end was smooth and circular, like a stethoscope's diaphragm. “Check this out,” she said, and plugged it into the wall, holding the other end to my bare waist.

A little lightning icon lit up on the circle, and when she let go of it, it stayed attached to my waist. “It's got an electromagnet that keeps it on,” she explained with an excited grin, “and it charges your insides through your skin! You could stay inside twenty-four seven if you wanted to!”

“That is... really cool.” I sagged. “But... I am so not up to that. I wanna—Mark wants to go to bed.”

She sighed. “Okay, fair enough. Just... let me leave the room first.” She sidled around me and backed out of the bedroom. “I don't wanna watch you turn yourself inside out.” I shrugged as she closed the door. “Oh,” she called through the wood, “to exit you say: Erotech Override, Disengage Suit.”

I frowned. It was the second time she'd wanted me to be more... Jen. What did that mean, exactly?

Getting out of the suit was pretty easy, compared to getting in. I pulled the vaginal opening wide, then down over my legs, revealing the sleek robotic undercarriage beneath. From there it was a simple matter to pull the skin up my waist and over my head, like a tight-fitting shirt. I dropped it on the floor, leaving a bare robot body. After taking a moment to ensure the suit was facing the right way out, I glanced at the mirror, did a little wave goodbye, and said, “Erotech Override: Disengage Suit”.

The back opened with a little hiss, and the probes pulled out of my body—I winced as they left, but luxuriated a little at the cool air on my regular human back. Then I pulled myself out—taking extra care with the dentures and nose tubes—and carefully lowered myself to the floor.

Now that I was out, and just Mark again, a few things became noticeable. My skin was covered with a fine layer of sweat, my ankles and wrists were a little stiff (but nothing too bad), and it was definitely easier to breathe. But more than all of that, I felt so... small. Such a tiny regular human.

When I opened the door, and saw Robin standing at basically my own height, I couldn't help but feel disappointed. Thankfully, that feeling went away when she stepped in and gave me a kiss as passionate and tongue-filled as any she'd blessed Jen with. “You,” she said as she pulled back, “were so good.”

“It was great for me too,” I said, laughing a little. “Thanks for everything.”

“Don't thank me yet.” She smiled. “We've barely even started.”

The bed was still very broken, so we pulled sheets and blankets from it and lay on the couch cushions, leaving Jen alone in the bedroom. Robin fell asleep quickly at my side—she was the quickest, heaviest sleeper I had ever met in my life—but I stared at the ceiling a little longer.

Why are you acting like plain old Mark in a woman suit?

–

I took a deep breath, held it for five seconds, then let it out. Then I sat on our new couch, picked up the pencil with my giant fingers, and wrote, Hello, my name is Jen on the piece of paper. The pencil's little scratches, and Robin's snores from the bedroom, were the only sounds in the apartment.

The pencil didn't even crack.

I smirked with Jen's mouth.

It had been a few days since Christmas, and they had been great days. Pretty much every day after work (or just in the afternoon for weekend days), I'd suit up as Jen, grab Robin, and fuck her until she couldn't see straight. Robin, meanwhile, had wasted no time buying new furniture: a reinforced bed, a sturdy couch, and a bunch of other items that could stand the weight of someone like Jen. And I hadn't hesitated to fuck her on all of them.

But I couldn't get that question out of my mind. Why are you acting like plain old Mark in a woman suit?

So, after Robin had gone to bed (thank goodness she was such a sound sleeper), I'd suit up again.  Night after night to practice walking around, writing, typing, all sorts of things. I wasn't sure what it was Robin was looking for in Jen, but I figured that whatever it was, I'd stand a better chance of pulling it off if I had full control of the suit's functions.

I sighed, pushed myself off the couch, then dropped down for my third set of crunches that evening. Besides fine motor control, I'd been working on endurance. My aim was to be at least as energetic in the suit as Robin was out of it, and considering that the suit was somewhat draining to wear, that was a challenge.

By the time I finished my reps, I was gleaming with sweat. One thing Robin had told me about the mechanicals of the suit was that it had an internal store of water, replenished whenever I drank, that got used for everything from saliva to vaginal secretions. I still didn't get what was stopping her from showing me the rest of the manual: she'd hidden it and I didn't know where to look.  

In any case, it was too late for this. I walked over to the bedroom and reached for my slit. As I was reaching, my intent was to pull Jen off and get in bed; by the time I'd actually gotten down there, that intent had dissipated. To hell with it: I was too tired to deal with that.

With a yawn, I fell into bed as I was, right next to Robin. The mattress bounced her a bit, and she murmured for a second, but didn't otherwise react. Thank goodness she was a heavy sleeper.

My left hand reached out, grabbed the charging cable, and pressed it against my hip to adhere there. My right hand stayed buried within me as I let my head fall limply to the side, staring over at Robin. Her short black hair fell messily onto the pillow, framing her pretty little face.

(a little ring of pressure, of pleasure, ran up and down my trapped member)

She was so beautiful. My motions got faster, less careful and less quiet, and I started making little grunts, pushing more fingers in.

(the ring got wider, moved faster, gripped harder)

I hadn't yet climaxed from masturbation as Jen. After all, almost all the time I wore her was time I was spending with Robin, and whenever she saw me taking care of myself, she'd jump in and take care of me instead. But Robin was asleep now.

(it was vibrating now, intensifying as I sped up, and there seemed to be no limit to it)

“Oh,” I whispered, “oh, oh.” I groped at my breasts with my free hand. The bed rocked as I squirmed, and pressure built in my nether regions. My right hand was moving so furiously that I was snagging bits of my hair as I went. I closed my eyes, imagining for a moment how I must look—flushed, desperate, longing.

(couldn't hold out any longer)

As I opened them, and as I saw Robin again, I climaxed.

My hips bucked half a dozen times, and my hand got slick with the suit's cum. I let out a satisfied sigh, wiped it on my midriff, and then rolled over a little so I was facing Robin with my whole body.

Slowly, I leaned in and kissed her forehead. “I love you so much,” I whispered. I reached one gentle hand around and pulled her closer to my body, so that I was draped over her. In that comfortable position—though really, every position was comfortable for Jen—I fell asleep.

I just wish I knew what you wanted.

–

“Hey,” said the little whisper.

I felt all swaddled up and warm, and very lazy. I didn't wanna wake up.

“Wake up, sleepyhead.” A hand was rustling through my hair.

I rumbled and opened my eyes. Robin smiled back at me. “Good morning, Jen,” she whispered.

Oh. Right. I was still in the suit.

“So how was it?” she asked, scooching a little closer under my arm.

I smiled. Then I pushed my right arm under her body and held her in a tight hug—not tight enough to hurt, but enough that she wasn't getting out. “Noooo, I need to go to worrrrrk,” she whined, but she didn't sound all that concerned.

“Call in sick,” I said.

“That sounds great. But seriously, I should probably—”

I leaned in close to her ear and hissed, “Call in sick.”

She got all still and flushed. “Okay,” she whispered back.

–

That was the day before New Year's Eve, and the two of us had both the eve and the day off. When I finally got finished with wearing Jen, I took her off and got a shower, luxuriating in the thoughts of the two days we'd spend together....

And then I got out, toweled myself off, and saw Robin packing up. “What's up?” I asked.

“What do you mean, what's up?” She didn't look up from her packing.

“Like... where are you going?”

“Spending New Year's with my college friends?” She gave me a stare. “You know, from theater class? Come on, Mark, I told you about this like three weeks ago.”

“I... guess?” I squinted: it was hard to be sure. “I kind of figured we were gonna spend more time... together?” I raised my eyebrows twice, meaningfully.

“That sounds amazing, and you were so good today that I'm almost convinced, but I kind of promised them.” She sighed sadly. “I've gotta get going quick if I don't wanna miss my train. Don't have too much fun without me!” She hefted her duffel and walked toward the door.

“Uh... Happy New Year?”

“Happy New Year,” she said, smiling back at me. Then the door shut.

I went to bed quickly that night, leaving the suit in the closet. Robin wasn't even going to be here. What was the point of practicing?

–

“Thirty eight, thirty nine, forty. All right. No pain, no gain. Forty one, forty two....”

The voice was familiar, although I wasn't sure why. But it wasn't the familiarity of the voice that woke me up, that got my eyes wide with concern. It was the existence of the voice. In my apartment, where no one else should be.

And then I glanced over at the closet. And it was empty.

“Forty seven, forty eight, forty... niiiiiine....”

Okay, not completely empty. There was the usual assortment of bedsheets, formal wear, and out of season clothes. But when you're used to seeing a seven foot tall robot woman in your closet, the closet definitely looks empty when the robot is missing.

And now I knew why the voice was familiar, yet strange. It sounded different when I wasn't the one using it.

My heart pounded as I crept out my bedroom door and saw Jen. Jen, in loose-fitting track-pants and a sports bra which I'd never seen before, standing next to a rack of weights that we didn't own. She faced away from me, which meant I could see how her massive hair had been wrangled into a loose ponytail. In her hands were the two weights from the bottom of the rack, and she was doing curls.

Jen. Moving, as far as I could tell, on her own.

“Fifty!” With a little shout of triumph, Jen brought the right weight up one last time; then she crouched down and placed both of them on the floor. She stood and did some stretches with her arms, still facing away from me.

“Um,” I finally managed.

She stopped mid stretch, then looked over her shoulder. “Oh, hey. You're her boyfriend, right?” Keeping her eyes on me, she turned around slowly, showing off a front that was just as coated with sweat as her back had been. “Hm. Thought you'd be bigger.”

“Hh. Uh?”

“I guess I woke you up, huh.” She shrugged in a rotating motion, apparently trying to release tension in her shoulders. “Yeah, your girlfriend said I could make myself at home, and at home I always do my morning reps first thing, so... tough, I guess.” She stuck out her hand. “Nice to meet you. You're Mark, right?”

“Erm.” I took her hand. Then winced as she shook it, squeezing hard enough I was worried something would crack. “Uh, what are you doing here?”

“Just passing through. Robin said if I was ever in the area, I could crash at her apartment. Got a problem with that?”

“Rrrright.” I got my hand back, and held it gingerly with the other one. “But... uh, who are you?”

Her eyebrows furrowed. “That's insulting. She really never brought me up?” A smirk broke out on her face. “The name's Jen.”
