Back to the lab.

While Blue was making use of his new living fleshlight, Professor Oak explained to him the next steps he needs to take.

"Wow, getting right into it I guess. I don't blame you, that girl looks like she can out suck a Swalot. Once your done with her, bring her to the lab. You need to get her registered."

"Wait, you weren't kidding about the **** stuff? I can actually register her?"

"No that was all Tauros shit. But who's going to tell me that I can't make this a thing? Lance? That pussy is too busy being cucked by Bruno to worry about the rest of the region. How do you think trainer's forfeiting sex became a thing in the first place? I can do whatever I want."

Blue, distracted by the throat fucking, didn't question this. "Yeah whatever Gramps. I'll be there after I am done with this bitch. Speaking of which, fuck, get ready for the first of many loads coming your way!"

As perverted as Oak is, he did not particularly want to see his grandson shoot his goo. Before it could happen, Oak walked back into the lab to get set up.

Soon after, Oak heard the doors opening and turned to see how much Blue had fucked Amber up. The answer?

A lot.

Amber was on her knees, crawling after her new master. Blue had her by the hair, being careful to only touch the clean parts. Which, honestly, is quite the accomplishment because she looked like she had fallen head first into a jar of mayonnaise. Amber's hair was knotted and sticky, bunching up in the parts Blue had grabbed before. Her face was coated in the slowly drying cum, still dripping off in thick drops every now and then. She had one eye open, the other needing to be cleaned off (Not that that was going to happen anytime soon). Under the baby batter her makeup was clearly running, giving her raccoon eyes and black streaks running down her face. Her shirt was now completely soaked by semen and her own spit, making it clear as day what was going on underneath. Amber's black bra was much too small for a girl of her size, barely containing her giant breasts. Her trademark vest was stained as well, hanging off of one shoulder in a way that Amber didn't seem to notice. If that wasn't enough, someone had spat on her face, a contrast to the white coating the rest.

In short, she looked like a total whore.

"I see that you have already taken the liberty of asserting your dominance over her. That's good, but now you should register her." Oak said, ignoring the pleading eyes his previous student. "Can I have your Pokedex?"

Blue huffed. "Whatever you old shit. Just make this quick. We have a lot of stuff to do today, right cocksucker?"

Amber looked up, her voice small. "...Please, let me.."

"Shut up! Did I say you can talk?" He spits on her once again, successfully making her recoil. "Only people are allowed to speak. Your worth less than a Pokemon."

While this exchange was going on, Oak was modifying Blue's Pokedex. After a minute of tinkering, he holds it up. "Here you go Blue, a new modified Pokedex! I call it the Slavedex. This allows you to not only register any Pokemon you meet, but also any woman who becomes yours. Just point it at your slut and it will automatically archive them."

"Really? Let me test this out." Blue wonders as he aims the new device at Amber's disgraced form.

"Amber, the Bimbo ****! This slut shows poor decision making due to her tits and ass directing resources away from the brain during puberty."

"HEY!" Amber exclaims, quickly bracing herself before Blue's spitball hit her face.

"Shut up bimbo. I already told you that your mouth is for sheathing cocks, not saying stupid shit." Blue commanded. Suddenly, he looked like a light bulb had gone off in his head. "Wait, so if she is my property, like a Pokemon, does that mean I can name her like one?"

"I mean why the fuck not. I'll make it so that any name you give her is now her legal one." Oak said, invested in this new system he was creating.

"Awesome. From now on, Amber, you will be known as... Cocksleeve! I think that fits you way better anyways."

Amber, I mean Cocksleeve, wanted to protest, but she didn't want to be spat on again. Already she was getting accustom to following Blue's orders, and surprisingly, she found herself feeling strangely warm at the thought. "First he took away my reputation, my confidence and now my identity. I am nothing but a Cocksleeve to him, to the world now." She considered, feeling her pussy moisten every so slightly at the humiliation.

"Ok, Cocksleeve it is!" Oak said jovially. "Now you are ready to continue on your journey. Where are you going to next?"

Blue smirked. He knew exactly what he was going to do next. "I'm gonna..."
