Ethics In Marine Biology Pt 02

This is Part 2 of the series, so go and read Part 1 if you missed it. I'm not sure this will make much sense otherwise.

Our heroine has lost her tentacle virginity to River, and is looking to return the favor. She's going to focus on them, but she might still get something out of it. We rejoin her in the afterglow of her first orgasm.

As they wipe me clean and collect what they can, I fluff out my tangled hair and sit up. There's not much point in being coy. "River, what can I do to make you cum? Clearly two tentacles inside me worked pretty well."

They glance at me, appearing embarrassed. "I'm not sure. The combination of the two didn't seem to overwhelm me, but I have more tentacles than you could ever attend to."

I'm almost offended. "Well, hold on now. I'm not going to give up that easily. I'm a scientist; I need to find out if you can even cum, and I'm not stopping until I do. And I get off on giving pleasure, so we're still getting you fluid at the same time."

River still seems apprehensive. I probably was when I was a virgin too. I'll have to be delicate.

"Look, I'm not going to force you to do anything you don't want to. I just want you to feel good. How about we go slowly, and focus entirely on you?"

They set the bowl down, looking at me and smiling. "I suppose that's alright. I feel as though I can trust you, and I can't deny curiosity in the matter."

That'll work for me. I grab a tentacle and pull them down on the couch next to me. I plant a quick kiss between their eyes and swing my leg over them, straddling them on the couch. I lean back onto their robes and feel a mass of tentacles swirl underneath me. Enough of them swirl across my still-aching clit to make me grind my hips against their lap, but I quickly remember what I'm supposed to be doing. I shake my hair out and run my hands over my chest, vamping while I think of what to try first. River appreciates my efforts, staring hungrily at every inch of my naked body.

I smile, loving how quickly the roles have reversed. Something about the give and take of power always drives me crazy; the dom becomes the sub and we keep switching until we pass out. The mass of tentacles on River's face wiggle in anticipation. That gives me the perfect idea.

I put my hands on River's shoulders and cock my head to the side. "Humans are mammals, remember? So females have two very sensitive spots that need constant attention. Do you think you can do that for me? Attend to my needs?"

River gulps, managing to finally meet my gaze. I smirk, recognizing the helplessness of this virgin in my experienced hands. I bring one hand behind my back to undo the clasp of my bra, letting it fall to my lap. My nipples pop out, sitting dead center upon two pale, rounded breasts. I pull my arms in to push my tits together, making them appear fuller and perkier. I've always been proud of my tits, but it doesn't hurt to go the extra mile.

River is still silent and transfixed. I lean in, hoping they get the message. Whether they do or not is a mystery to me; I can't see their expression as I push my tits in their face. But their body reacts correctly. I can feel the squirming mass of tentacles tickle my breasts, poking and prodding whatever they can reach. Eventually, a pair pinches my nipples and starts to pull on them, reminding me that I'm still coming down from my orgasm.

It feels wonderful, and I moan gently to let River know they're doing something right. I twist my torso side to side, grinding my sensitive nipples against every tentacle on their face.

I want to know if this is working for them, so I lean back. River's expression is of bewildered glee, as though nobody had ever pushed a full rack in their face before. I can't blame them; my tits are pretty perfect.

I'm so taken with the look on their face that I blurt out my desire. "Can I kiss you? It's such a simple thing, humans usually start with that. I guess I don't know if you even have a mouth."

River nods, looking for the right words. "I'm afraid I don't have human lips under here. The closest thing I have is this," and they part their beard of tentacles to reveal a flat, thicker tentacle above their chin. It reminds me of a tongue, but it's definitely longer and greener than any tongue I've ever seen. I can work with that.

I don't voice my intent, though. I just dive right in.

I gently take River's face in my hands and descend upon them, pecking them all over faster than they can react. I lick and nibble on the beard of tentacles, making sure to attend to each of them in turn. I nuzzle my face into the writhing mass, hunting for that elusive tentacle. When I find it, I immediately lick every inch of it clean. It's bumpy like a tongue, and feels just as powerful. I circle my hand around its base and shove it down my throat, letting it explore every nook and cranny in my mouth.

It slides much deeper than I expect, but I manage not to gag. It's difficult to use my own tongue, with how much room it takes up in my mouth. I do my best, wrapping my tongue around the tentacle, pulling it deeper down my throat. To my surprise, it starts to vibrate. I slide my lips off it and realize River was trying to talk.

They sputter, "sorry, I should have mentioned that. I vocalize through that tentacle, so it vibrates whenever I speak."

Usually, I'd be fascinated by the implications of an external vocal cord that works just as well as a human's without needing to be attached at both ends. But right now, all I can imagine is a long, thick, vibrating tongue inside me. I open my mouth to beg River to do that, but remember who's supposed to be getting off right now. I'll save that for next time.

The attention I've been giving River's face seems to be working. Their mass of tentacles are squirming desperately below me and their eyes are pleading for more. I can see droplets of pre-cum dripping from every tentacle in their beard, so I'm sure the ones beneath their robe are just as bothered.

I ask, "Can we keep going? I want you to touch every part of me... Every. Part." I reach down and circle my clit with my finger, making sure that River can see how sensitive I still am. My other hand massages my tit.

They nod eagerly, not appearing to know how to verbalize their desire.

I fall on the couch next to them, lying back and spreading my legs. "You're going to need to wrap me in tentacles. Every inch of me..." I move my fingers slowly up my body, dancing over my most sensitive areas, "needs every inch of you."

They stand up and reveal too many tentacles to count. Before I can guide them, the tentacles begin circling my body until I'm lifted from the couch. I'm hoisted up like I weigh nothing, and it makes me feel like I'm floating in space. I could fall asleep if I wasn't being molested in every sensitive nook and cranny.

The closest thing I've ever felt to this was when I got my ex to try full Shibari. I had to teach him all the knots, and he was exhausted by the time we got me naked and hoisted. He barely had the energy to fuck me, and then untying me was even more difficult.

This is infinitely better. The tentacles are soft and strong, holding me gently despite how high I am. My arms and legs are restrained, but my weight is distributed evenly. River even supports my head, propping me up with a couple tentacles so I can look right into their eyes.

But River hasn't cum yet. I ask them to let go of my arms, and try to find the two smallest tentacles in the tangle. I find the perfect pair, each about 2/3 the size of the largest ones. I gently wrap them around each other, ensuring I kiss and stroke them throughout the process. River doesn't complain, so I'll have to assume they like this.

Once I have a twisted pair of tentacles, forming a rod much larger than any single one, I push it down towards my pussy. River doesn't quite know how to control their new appendage, which almost makes me laugh. It wobbles clumsily, and eventually smacks down on my clit harder than River intended. I gasp in pleasure and thank god that I'm still so aroused. That would have hurt like hell if I wasn't.

I take the unholy creation in my hands and align it with my entrance. It's almost pouring pre-cum at this point, soaking my pussy more than it already was. I lock eyes with River, asking for consent one last time.

They gulp, nod, and push it inside. Even with as wet as we both are, it's not an easy fit. I pull my thighs apart and hold my breath, wondering if I bit off more than I can chew. The head pushes inside, and I let out a little scream in pleasure. I think the worst is over... but River was pushing too hard.

The first thrust bottoms out inside me and nearly knocks me off the bed of tentacles, and I scream in surprise. They catch me at the last minute, wrapping around my ass and pulling me back up.

So now I'm full to the brim, having difficulty breathing, wrapped in prehensile dicks, and staring at my yet-to-cum partner. Usually this isn't the part where I have to explain things, but River not moving indicates otherwise. And I'm too impatient to let them get there on their own.

Between gasps, I say, "This is- amazing- I'm so full- of you- Can you start- moving-? And tell me- if it feels good."

They nod, reassured that I'm not taking too much. I close my eyes and wait what feels like an eternity before the tentacles inside me pull back, then thrust inside just as hard as the first time. I can't hold back my voice; I yelp with every thrust and breathe in when they pull out. When I finally remember to do so, I look down as River to see how they're taking this.

Their face is contorted in what I have to assume is pleasure. They're making little grunts when they thrust in and don't appear to realize it. I'm practically sliding around on my back with how much pre-cum is leaking out of the tentacles below me. I let this go on for a while, riding the high of being fucked by the thickest dick I've ever had. My whole body moves when they thrust, and I'm pulled back just in time for another. Penetration always amazing after I've cum, and I can feel another orgasm building. If I time it right, River and I might be able to cum together.

In the moments between River bottoming out inside me, I pull tentacles out of the tangle below me. I wrap one around each of my tits, making sure the heads rub against my nipples. I pull one into my mouth, leaning back so I'm effectively spitroasted. The last two I keep in my hands, jerking them off with their own pre-cum. We're basically back where we started, but now my pussy is twice as stuffed. I pop the tentacle out of my mouth and check on River's status.

From what I can tell, they're barely holding on. I ask anyway. "Are you- getting close?"

They don't respond right away. When they do, they're almost as strained as I am. "I'm not sure... it feels like I'm getting there... but I can't seem to... get over the last bit..."

Talk about high-maintenance. Luckily, I've got just the thing. I let go of their tentacles in my hands and reach down below the dick fucking me. I spread my cheeks to reveal my asshole, drenched in pre-cum and winking as my pussy gets stretched.

"Fuck me- here too. Just use a- small one- I'm not super- experienced with- my ass-"

This time, they don't hesitate. A smaller tentacle presses against my asshole, trying to worm its way inside. It doesn't take long with how soaked that whole area is. It pushes inside me, and I scream long and hard. I'm fuller than I've ever been. My pussy and ass squeeze the tentacles hard enough to destroy a normal dick, but River looks hornier than ever. I jerk off two more tentacles and nod to River, begging them to fuck my brains out. All three tentacles thrust in at once, and the wind is knocked out of me. They pull back, and I can breathe for a moment. But then they're back in. And out. And in. And out. And in.

At some point, the tentacle I was sucking off finds its way back into my mouth. It fucks my throat mercilessly, using me like any other warm hole. I'm barely aware of it; nothing can distract me from the pressure between my legs.

I feel whole when they're smashed deep inside me, and empty when they recede a single inch. I don't remember what it was like before I had tentacles inside me, and I don't want to. I don't know if I'm even screaming anymore or just taking it like a common whore.

My growing orgasm brings me back to reality. As amazing as I'm feeling now, it's about to drastically improve. River has begun moaning outright, and I can tell even without seeing them that they're going to join me. The last thought crossing my mind before the world goes white is whether human-octopus demons are sterile.

My pussy and asshole squeeze like a vice around all three tentacles, and I wail in ecstasy around the tentacle in my throat. That pushes River over the edge, and the results are explosive. My womb, stomach, and lower intestine are flooded with cum. It spurts inside me, immediately overflowing. The tentacles seize as they struggle to push their payload as deep inside me as possible, but nearly all of it fails. Cum is bursting past my lips, streaming down my legs, and pouring out my ass. I can't believe they're still cumming; it's been almost 30 seconds now. I guess they've been saving it up.

After depositing a lifetime of cum, River slowly slides their tentacles out of me. I cough as the first leaves my mouth, trying and failing to catch my breath around all the cum left behind. It tastes a lot like human cum, but it's slightly saltier. I don't even bother to try to swallow any; I got plenty already.

The tentacle in my ass pops out and my ass remains gaped open, needing some time to return to its proper shape. The tentacle in my pussy drags its way out, and a fountain of cum erupts after it. If there's any chance of pregnancy, I am well and truly knocked up.

River falls back onto the couch, and I'm dumped on the loveseat across from them. Their tentacles sprawl about, covered in white cum and my own fluids. Without meaning to, I pull the one closest to my face into my mouth, sucking it clean. I'm falling into my old ways, acting like a cock-hungry slut without shame. The cum tastes so good, despite how full I am.

After a minute of catching our breath, River and I look at each other. Another eternity later, they speak first.

"I suspect that worked. It was truly a magnificent experience. I'm not sure I can separate my own fluids from yours, but I can't say I regret doing that. Thank you again."

Something about their earnest appreciation makes me proud. Like I did my good deed for the week, even if I was a horny mess while I did it.

But I'm quickly returning to reality. Now that I've cum twice, I notice what a disastrous mess my lab is. It's been an hour since I clocked in, no experiments have been done, and I need an explanation for all those stains on the couch. And River has some curse they're still trying to cast. Maybe we should start with that.

"Hey River. What kind of demands did Doris have? You said she wanted to rebalance the power dynamic, but did she have specific requests?"

They hesitate for a moment, appearing to have forgotten why they were even summoned. "Oh yes, Doris's request. Her stated demands were that the octopuses of the lab be given one day off a week without experiments and two guaranteed treats a day, regardless of performance."

That can't be it. "Wait. That's it? That's what she wanted?"

They shake their head in frustration, misunderstanding my question. "I knew you wouldn't give up power so easily. This process could have been enjoyable, but I'll take no further pleasure in extracting your essence."

I have to clarify. "No, River. That's totally doable. I honestly didn't even know they were sentient; I would have been treating them so much better! I can do exactly what she wants, you don't need to curse me. We can stop collecting fluid."

They look surprised, but not agreeable. "Be that as it may, my charge is unchanged. I am to ensure your cooperation, and I'll be using this curse to do it."

They pull out their spellbook again and read from the text. "...or other substance in which the victim's essence can be derived, is required for this curse to function. The victim must be of virgin purity, mature age, and sound mind." They look at me with annoyance. Wait, what was that last part?

"River... what do you think the phrase 'virgin purity' means?"

They cock their head to the side, as though the answer is obvious. "Well, I always assumed it had something to do with the type of prey you consume. Do you keep a proper diet?"

I can't help but laugh, and it takes me a while to stop. River doesn't seem to get it.

Once I recover, I put a hand on their shoulder. "River, I'm so many things. But I'm most definitely not a virgin. I'm sorry your curse won't work, but I'll do exactly what Doris asked. Your job here is done."

I see the realization on their face, followed by embarrassment, followed by frustration. They say, "I've never failed a task before. Demons are rarely summoned, and I doubt I'll be summoned again soon with this embarrassing performance."

Now I feel bad for them. "You really didn't fail, I'm doing exactly what she wanted. And I'm so glad I met you, I truly don't know how I would have felt something like that without you."

It occurs to me that I might never see River again. I'm well out of the Fog of Lust now, but I can't help but be mad that I finally found the perfect partner, only to lose them. But maybe I don't need to? How can I get River to stick around?

I seduced my way into this problem, so maybe I can seduce my way out of it. "If you feel that bad about it, maybe you could stick around for a little longer? Just to see if I'm keeping my word. Doris can send you back whenever you're convinced. And I..." I reach out and grab another tentacle, still twitching by itself, covered in cum, "could probably find something for the two of us to do in the meantime." I hold the tentacle in both of my hands, gently squeezing it while I lick it clean. Can't forget to clean up after myself.

River looks defeated, but can't manage to hide their joy. "I suppose that might help. I'm curious about further... sexual experiments we could perform. I've only cum once in my life, of course."

I smile, knowing I'll never have to think about my ex again. This is going to be one hell of a shift.

I lie back down on the couch, surrounded by spent tentacles and the smell of sex. I stretch my arms and legs, feeling limber and sexy, not caring about a thing in the world. I rub my clit gently, checking how sensitive I am after my second orgasm. Turns out, I'm just sensitive enough.

I spread my legs, letting another load of cum spill out of my pussy. I look at the demon in front of me, all the desire in the world written in my smile. "I've got an hour left in my shift, River. Want to run another experiment?"

---

Two weeks later, I'm checking into the lab again. River comes and goes as they please, popping in and out of the demonic plane at their convenience. I barely have any time for my job with how much we fuck. I won't see them today, as this shift is shared with my boss Helen. I haven't quite figured out how to break the news to her that demons exist, they're at the beck and call of our test subjects, and I've been consistently getting my back blown out on the clock. She'd probably be jealous of me anyway.

Helen opens the door and says hi, getting right to her desk and pouring over this month's data. She looks a little more disheveled than usual, so I decide to ask. "Boss, how're you feeling? Did your date go okay?"

She looks at me with exhaustion. "Not even close. This guy was stunning, sweet, and probably hung like a horse. But he told me he was waiting for marriage, and didn't even want a handjob. So I was up all night for no reason." She's usually a bit more professional, so she must really be bothered.
