A/N: The last chapter seemed to have some mixed responses. Well, this chapter doesn't exactly advance the plot either...but hopefully it makes up for that!

Under no uncertain terms, I had been temporarily confined to our home dimension. Which...was fine, really. I had some objectives I intended to pursue, but they weren't time-critical now that Echidna wasn't about to be released – and furthermore, after that fight I was willing to take a break regardless.

So I spent my time catching up on PHO, being amused at memes of Saena and I, and doing a bit of research.

And...studying the House a bit more. I'd dug deeper into the portal settings and found the "new world" options – there was a sort of progress bar that filled as we 'completed objectives' in our current world. Once it was full, I could empty it to generate an initial portal into a new world. The bar would empty, and we could fill it again by capturing more waifus for the Company, or completing 'narrative goals,' and so forth.

Alas, it appeared that the world selection functioned like a gacha system. There were a few different 'banners' I could roll on, and there was evidence that they could shift and change with time – 'modern fantasy' was one of the current ones, as were 'supernatural' and 'science fiction.' Or, if I was feeling masochistic, there was always 'death world.'

According to the help files, there was a heavy bias towards worlds that I knew at least something about, which would be helpful.

Still, it wasn't quite relevant – we hadn't filled the portal bar for Earth Bet yet. Which...was a bit irritating. In most worlds, I'd assume defeating something like an Endbringer would produce a lot of narrative progress. Then again, in terms of Worm's scale, I suppose it wasn't quite story-ending material. Still, we were almost finished with it, at which point I'd be able to open up a new world of some type.

A vacation from Earth Bet sounded quite nice at the moment, really.

Outside of that, I'd made some preemptive adjustments and increased the size of Riley's lab, among a few other minor changes. I would soon be becoming a dragon, after all, and I was certain that she would want to take a look at how exactly that worked...and I was curious what kinds of brilliant and/or insane upgrades she could conjure up for a dragon.

Speaking of Riley...I glanced down, briefly catching the eyes of the small blonde girl clinging to my chest before she looked away blushing.

She'd returned to my bedroom every night to sleep pressed up against me. Saena had remained mostly quiet on the subject save for a vague feeling of amusement.

I reached up to ruffle her hair and she made a content little humming noise for a moment before placing both her hands on top of mine and looking up at me.

It was...a pretty adorable sight, to be honest. All that was missing was a pair of cat ears, really.

She stared up at me, and I looked at her. She blushed, but held my gaze. Then she fidgeted in my lap for a moment.

Finally, she bit her lip before speaking. "Why haven't you done anything?"

"Hmm?"

"I kissed you before you left, and...and I've been waiting and waiting and waiting but you haven't done anything!" Her pout was in full force now. "Why?"

"I –" Whatever I'd intended to say vanished from my head when she pulled my hand off her hair and laid it on her bare thigh. Then, without hesitation, she slid it further up her leg, underneath her nightgown – and I found myself with a solid handful of her bare ass. I'm sure some unintelligible noise came out of my mouth.

"I kept waiting for you to notice and you haven't. I...I want you to do –" she pursed her lips for a moment, "– to do those sorts of things with me too..." I squeezed her reflexively, and she moaned in the back of her throat, grinding back against my hand. And, like that, any logical thought I had evaporated. "My...I made sure my body's ready for what-whatever you want, just...please."

Evaporated and disintegrated. I lifted her off of my chest (she was so small and light compared to me), and started somewhat awkwardly rolling us over. "Well, if we're going to, then we'll do this correctly."

Then she was plucked out of my arms with a squeak as Saena's wings wrapped around her, pulling Riley up against her torso and gently spreading her legs to either side.

Ah. Thank you, Saena.

{Affirmative.}

"Ah, I, um, I don't really know – I mean, I've done research, and I've...I've watched you, but...uh, wait –" Riley was babbling, blushing brightly...but she was also breathing heavily, her chest heaving between every few words.

I raised an eyebrow as I slowly climbed between her legs. "You watched us?"

"Um...maybe a little...a few times?" She hid her face in her hands.

"Did you enjoy it?" I leaned in, gently kissing the inside of her thigh. I could feel her muscle twitch like she was trying to squeeze down on my head, but Saena was holding her legs in place.

"...yeah. a lot," she mumbled into her hands. When I started trailing up her thigh, she bit her lip. When I nipped at her skin, she let out a shuddering breath. "Um...what do I...what do I do...?"

"Nothing," I told her from between her legs, my focus drifting away from her face. "This is your first time – the only thing I want you to focus on is how it feels." Her pussy was cute, I decided. The inner lips were completely tucked away and hidden...but despite how tight and closed off it seemed, she was still obviously soaked.

"Um, but –" she started.

I slowly drew my tongue up along her pussy, and she cut off with a squeak, reaching down for my head before hesitating and clenching her fingers around the hem of her nightdress instead.

She stared down at me with wide eyes as I explored her. I dipped my tongue between her folds, teasing and testing her lips. I lapped gently at her entrance, becoming acquainted with her unique flavor. I teased along her slit with the tip of my tongue, and I lapped at her entire pussy with long strokes of the entire muscle. Each movement brought new little gasps and whimpers from her as she bunched up her nightgown, torn between lifting it up higher to get a better view and concealing the embarrassing sight of me devouring her.

I lived for those reactions. I teased them out of her carefully, one by one, guided by my own experience and even further by Company fiat. I teased at her clit and quickly found it was too sensitive, at least for now, so I simply let the tip of my tongue wander near to it without quite touching it.

Finally, when she was a panting, quivering mess, I could feel that it was the right time. I wrapped my arms around her legs from beneath, pressing my face tighter against her sweet slit, and pressed my tongue inside. She gasped, legs tensing around me, and I spent a while licking just inside her. Each movement of my tongue brought another little twitch, another murmured word.

And she was ready. I flexed my jaw just a bit and let my tongue extend – not fully, not quite, but just enough to let the tip of it lap at her g-spot.

The moment my tongue touched it she screamed, a high-pitched note of pure release, and her hands immediately released her nightgown and clamped down on my hair as her hips pressed upwards against my face, muscles twitching and quivering as her body fired on all cylinders. I simply kept calmly licking at that treasured spot, tasting her cum as it poured into my mouth and loving every second of it.

Bit by bit, her breathing slowed even as she kept bucking her hips in time with my movements, and her mumbled nonsense resolved itself into words. "W-wait, waitwaitwait, I want...I want more, I want you to...to do bad things with me."

I hummed, tongue still inside her, and she shivered. She tugged at my hair a bit, though, so I (reluctantly) separated myself from her slit. "Bad things? Aren't we already doing those?"

She blushed, eyes glancing away from my face. "I mean...I want...I want you to fff...to fuck me."

Well. If she was going to put it like that. I rose to my knees between her legs and freed myself from my pants, amused at the way her eyes immediately dropped to my dick.

I moved forward, and for a moment I just laid it on top of her slit, enjoying how far up her body it reached. She's so much smaller than me. It feels...pretty wrong, and at the same time amazing.

She licked her lips. "I want...I want that. All of it." With visible effort, she looked into my face again. "Please?"

Fuck, if you're doing this by accident I shudder to imagine what you'll become once you're corrupted properly.

I pulled back, slowly rubbing the tip along her slit, feeling heat and wetness and throbbing with anticipation. She wiggled her hips, grinding against the tip, trying to push against me. "Nooooo," she whined, "don't tease me. You've already teased me. Please, just –" I pushed it in, and her words devolved into a slurred mumble.

"What was that?" I asked, only barely coherent. When she opened her mouth, I pushed in slightly deeper, and a guttural sound emerged from her as her eyes fluttered closed. Slowly, I pulled out, then pushed back in a bit deeper. Bit by bit, I sawed my way into her tight cunt, fighting against the way it squeezed me as her muscles twitched.

The instant I bottomed out in her, Saena released her legs and Riley wrapped them around my hips, squeezing tightly and trying to press more of me inside her. Her pussy twitched and clenched around my cock and a low keening found its way out of her mouth, eyes half-open but not seeing anything.

Did she just cum? Already?

{Affirmative. Amusement.}

Maybe I should take it easy on her, if she's this sensitive.

{Negative. Unnecessary.} I glanced up at Saena, who was looking down at Riley with an inscrutable expression. She raised her eyes to meet mine. {Conquer without mercy.}

I twitched inside Riley and she mumbled something incoherent. Well. You haven't been wrong before. I reached down, wrapping my hands around Riley's tiny waist, and started actually fucking her. Slow, steady strokes with enough force behind them to slap our hips together. Whatever fuck-trance Riley found herself in, she managed to mostly meet my rhythm, relaxing her legs as I pulled out and pulling me back in desperately as I pushed forward.

I lost myself inside her. I have no idea how many times I plunged into her. I kept up a steady, slow rhythm until she clenched around me so tightly I couldn't move, gasping something I couldn't understand. As soon as she relaxed, I'd lost patience.

And so I pounded her. I pulled her waist against mine, slamming us together and feeling my balls bouncing against her ass. Her face had slackened, eyes half-closed and fluttering in their sockets, legs still vaguely attempting to pull me in but without coordination. There's something weirdly hot about fucking the bio-tinker until her brain and body both stop functioning. At that thought, I twitched, and took a moment to catch my breath, buried inside her.

She mumbled, grinding her hips against mine greedily, and I squeezed her hips in my hands. I thought I heard the word 'more' somewhere in those incoherent noises – so I obliged her. I leaned forward slightly, Saena automatically shifting her wings to give me support, and I slammed my hips downwards, bouncing Riley against the bed.

She made a deep, desperate noise with each thrust, her legs going slack...so I slipped my hands underneath her thighs and pulled them upwards, folding her to find the perfect angle.

I mating pressed her into the bed. With the first thrust, she must have gained some semblance of thought again, because her arms found their way up to wrap around me. Well...as much as they could. Her nails dug lightly into my skin as she tried to grip me, tried to find purchase, and I lost my mind.

I don't know how long I pounded the girl into the bed. I don't know how hard I did it, either.

I know when I finally came, I went blind for a solid ten or twenty seconds, and when I came to Riley was completely limp and filled with my seed. I knelt there for a moment, slowly going soft inside of her, trying desperately to catch my breath and wondering if I'd gone too far.

{Negative. Perfect execution. Engage aftercare.}

Expertly, Saena flipped us around, letting me slip free from the girl beneath me and draping her across my chest limply as I laid atop Saena's torso.

I blinked, drained from how intense the sex had been. Should...should clean her up before morning.

{Affirmative.}

The last thing I saw before I passed into sleep was a small ball of my cum hovering up from Riley's waist, on a collision course with Saena's mouth.

I woke to a pleasant sensation. Slowly, I stirred, feeling occasional jolts of pleasure distantly firing. When my eyes fluttered open, they were drawn to movement in my lap.

Riley was laying between my legs, dick draped across her face, gently trailing kisses up it from beneath and making pleased noises. "Mm," she mumbled in between kisses. "Good morning. I didn't...realize how...unsatisfied I'd been before...until I woke up this morning. This...this..." She slid her tongue along my cock in a long lick that ended in a gentle kiss. "This is so much better." Slowly, she teased her way towards the tip, smiling indolently and with dazed eyes.

She gently suckled just underneath the tip for a moment before pulling back, excitement shimmering in her eyes. "I was going to wait for this. Until I'd had a chance to install some extra nerve endings in my throat, you know? To enjoy it properly. But..." She leaned forward, and her next words were slightly muffled by the tip of my cock. "...I just can't wait, I don't think." Slowly, she wrapped her lips around it. "Amf I a bah guh?" She stared into my eyes as she lapped at my dick, waiting for an answer.

I slid my hand through her hair and she hummed wonderfully around my cock. "I think if you keep that up, you're a very good girl, Riley."

She closed her eyes, a happy sound coming from the back of her throat.

Then, she slowly worked her way down my cock, and I realized she'd removed her own gag reflex around the time her lips reached the base.
