The Dark Rebirth of Pandora: Revenge of the Abyss

Chapter 673: Grimm Part 3

”...Now, my silly little student, spread your legs wide. I want to study more things about that little body of yours.” She speaks while removing the top that barely covered my breasts and tugging at the skirt, which tears. She also finishes pulling off my panties, leaving me 100% naked.

”H-How could exploring th-this little hole be useful to you or to me?” I ask as she crouches down near me.

”Oh, of course it helps. First, I’m using magic, so I’m mapping your body’s activities. Second, I just now found an infinite and renewable source of tea!!”

”!!!”

”Y-You’ve got to be kidding me, right? Y-You’re really going to want to drink that, of all the things you could want from my body?”

”Uhum.” She just agrees, staring at my urethra as if it were fascinating.

”I need to teach you to release this without having to keep poking. It’s like learning how to pee.”

”That offends me. I’m not a child who needs to learn the basics!!” I say, totally offended, while she twirls the cylinder in her hands.

”Fine then. Let’s do this: if you can fill this cup here by yourself, I won’t do anything. If you fail, I’ll do it however I want.” She places a cup on the floor.

”...” I try to push, but how can I do something I’ve never had to do before? Ever since I became a girl and a Tenebris Abyssus, I’ve never needed to use the bathroom. My muscles aren’t ready, and they weren’t even made for this.

”...” A few minutes pass, but I can’t produce anything. Until a little while ago, I didn’t even know my bladder could do this.

”...I-I can’t do it...”

”What a shame. Well, I’ll teach you. You just need to understand how this works, Pandora.” She touches the cylinder to my urethra again. I feel like I’m going to cry from shame.

”G-Grimm-sensei, th-this isn’t fair to me. I-It’s beyond extremely degrading and dirty! Th-This little hole wasn’t made for you to keep shoving things into!!!”

”Oh, is that so? That doesn’t really matter, does it? I’m going to want my daily cup of tea, and as long as you can’t do this by yourself, I’ll need to help you.” She rubs it against the tiny little entrance.

”Nhhgghghhh!!!” My body writhes with a strange pain as she inserts it. The sensation of the blunt tip of the cylinder hitting against the closed little entrance is something unpleasant.

”Gyaaaaa!!!!” She shoves it much deeper, hitting the bladder wall, and uses some strange magic. I see black marks like lightning appearing on my skin and rising up before disappearing.

”Wh-What the hell are you doing?”

”Mapping. I’m discovering some very interesting things. Did you know that your blood, during regeneration, emerges from the same pure Mana in your bladder?”

”Stop!!! Stop depraving my biology!!! I beg you!!!” If she would at least tell me this without having to be penetrating my urethra, it would be far more acceptable.

”Ghmmm!!” She twists this thing inside me, almost making me collapse to the floor. Soon she pulls it out while more of that whitish fluid trickles out, dripping shamefully from my abused little hole.

”Lie down on the table, Pandora. I want to run more tests.”

”...O-Okay, Grimm-sensei...” I swallow my displeasure, obeying, because that’s what my existence as an avatar is for.

’If my original body ever comes back, I swear I’ll get my revenge’

...

...

...

”...O-Okay, Grimm-sensei...” Pandora says, her face deeply embarrassed. She sits on the support table I created, and I watch as her urethra leaks that delicious fluid.

”Spread your legs, my favorite student!!” I say to Pandora, who, despite her ugly expression, simply obeys. I place a chair and sit down, gaining total access to her vagina.

”Hhmmm... hmmmm...” I touch her urethra with the cylinder, listening to her moans. I start rubbing and gently twirling, using her viscosity as lubricant. She whimpers, but despite that, her pussy won’t stop dripping love juice.

”Gaaahh.” She lets out a little scream as my little toy hits deep inside her, forcing its passage inward. Obviously, I’m using some evaluation magic, genuinely curious about her body.

”Push, Pandora. If you push, you can gush out a lot of my new favorite tea. Don’t forget, I’m going to want to drink this every single day from now on, so you’ll have to get used to it.” It’s such a dense, sweet magic.

”...” Pandora bites her lips, trying hard to expel more of this fluid. A little starts leaking around the object as I train her muscles.

”Come on, Pandora. I’m going to pull it out, and I need you to be able to squirt.” I quickly pull out the object, making Pandora arch her back and cum hard. Along with it, her soft urethra shoots loads of fluids forward in a lewd display.

”See? It wasn’t that hard.” I say, licking my lips to savor what landed on my face. Pandora is having spasms on the table from the totally new pleasure she’s not used to.

”Guuuhhh!!!” Pandora makes a funny sound when I punch right on top of her belly, making her squirt more of those fluids and fill an extra cup I position beneath her. The viscous mixture smells good, almost floral in its fragrant touch.

”You can only handle this, Pandora? So pathetic!!” I shove the tube inside her, making it invade her bladder. But this time, I push much more of it inside, making Pandora writhe on the table.

”This tube is a total of 30 centimeters long. I made it to measure the exact distance from your vagina to your C-spot, but now that I’ve found something more interesting, I want to test how much we can get in.” Pandora looks at me with tears in her eyes, but before she can complain, I start pushing it in, stretching the path.

An obvious mark appears on Pandora’s skin, showing the invasive object as 20 centimeters enter, but her wall stops stretching. It’s within the average I expected.

”Haa... Haa...” Pandora pants on the table. It’s fun catching Pandora off guard with new fetishes. Her urethra really squeezes the thin cylinder tightly.

”Hmm, I think it’s easier to teach you to hold it in than to release it. I think if I stretch this little hole a bit, it becomes easier for you, right? So let’s keep this little thing inside you daily. Every single day for a few months, and we’ll train every day until you’re capable of filling a cup for me.” I analyze the collected data.

’Interesting...’ I map the entire complex internal structure of Pandora’s body. If only I knew all the races used as study bases for Pandora’s race, I could create my own artificial Tenebris Abyssus.

’All of Pandora’s organs, nerves, and bodily functions are like a single interconnected system.’ They aren’t separate things linked to the brain. They are a unique ensemble with varied forms. Her body is indeed a blessing of biological engineering.

’Either way, since this is only an avatar, I will mold it into a cute, well-mannered girl.’ I will turn Pandora into a true girl. Rid her of her bad mannerisms, her cursing, her way of acting!! I will reshape her entirely.
