She's learned her lesson, give her a baby.

Alright, you'd made your point pretty clear by now. The poor girl's legs were shaking with pain and exhaustion after fucking her own untrained asshole on your massive cock. The 18 year old whore was now completely yours and you were confident she would behave herself. She'd done a pretty commendable job, all things considered. With some practice, she could be an all-time great breeding slut, seeing as how her pussy was already almost completely trained. Who knows, you may eventually even consider drafting her into a sort of apprenticeship, but first thing's first - half of your meat was still lodged snugly up her ass. Further tutelage under your perennially tough and occasional fair guidance would have to wait. It was time to make a brand new teen mom.

You began to ease your cock out of Erin's battered asshole, very slowly so as to not cause her too much more pain. She still winced visibly as your throbbing cockhead finally popped out of her entrance. Your fat dick had completely stretched out her asshole, and a thin stream of precum was leaking out of it onto the floor. You aren't a doctor, but it didn't seem good. Then again, she's young enough that it'll surely bounce back quickly. Either way, you didn't really want to think about that anymore, so you turn Erin around and press her back against the wall. The bright smile had returned to her cute face as she looked lovingly up at you. She grabbed your slick cock with her tiny hands and began to stroke it, barely able grasp the entire shaft even with both hands. "Thank you for fucking my ass, daddy! I hope it was tight enough for you. Do you want my pussy now? Are you going to make my pussy milk your cock like a good breeding whore?" You grab her long blonde hair and pull her head back, staring into her eyes. Erin licks her lips and begins to stroke your rod faster. "You've been a nice little fuckslut for me. You have my permission to milk my cock with your pussy. Don't get cocky though." Erin giggles and slides her hips towards your pulsing tip. You choose to believe that she was giggling at your inspired wordplay.

You're so much taller than her that she has to stand on her tiptoes to slide herself down your dick. Her cunt is absolutely soaked and she easily slides herself all the way down the shaft, pressing her hips into yours. Erin wraps her arms around you and lets loose with an animated and girlish moan directly in your ear. "Yes, daddy! Let me make your cock feel good. I'm such a needy, slutty whore for daddy's dick. Make me a real slut!" You'd been getting your dick stroked in various holes for a while now, and you could feel yourself getting close. Your primal instincts kicked in, and you began thrusting heavily into Erin's pussy. She dutifully moved her hips back and forth in time with yours to let you shove yourself in as deep as possible. The depths of her young breeding hole were perfectly slicked with juices and it radiated heat all over your shaft. Erin fucked you like a perfect submissive whore, moaning loudly and using her body as a glorified fucktoy. She could definitely take cock like a pro, but there was no way she was ready for the size of the load she was about to receive. Your massive balls churned with semen, and you felt your orgasm building as you recklessly pounded the teenage pussy doing its best to squeeze the cum out of your dick.

You put your hands on Erin's shoulders and push her back into the wall, again staring down into her eyes. "I'm going to fucking cum! Look at me and beg for it like a good slut! Take it all!" you yell as you ram yourself as hard as you can into her pussy and nail her body to the wall. Finally, you shoot the first absurdly large rope of jizz deep inside of your 18 year old breeding slut. She stares at you as instructed, her eyelids fluttering in pleasure and relief. She grabs your hips and pulls them towards her to press your cock as hard as possible. "Fuck yes, daddy! You're making me your breeding slut! Fuck a baby into me like the trashy cumdump I am! Just fucking spray it deep inside me, daddy! I can feel your massive cock pumping such a big load in my pussy, that's all it's useful for! You made me yours with that fat fucking delicious cock! Fuck yes daddy!" Erin screams obscenities in a semi-intelligible manner as your giant penis continues to shoot load after load inside her. It isn't too long before the sheer size and strength of your cumshot pushes semen out of Erin's full pussy and onto the floor. You fire enough spunk to literally fill her up multiple times over before you finally finish spasming as a wave of relief washes over your body. There was something special about breeding young fertile sluts. Or maybe shooting a load in any random pussy just feels good, it was hard to say.

There was a fairly sizable puddle of cum on the floor. A collection employee could retrieve it, but why not let Erin retrieve it first? It was sort of the opposite of cutting out the middle man. "Get on your knees and lick up the cum you spilled," you order. "Yes, daddy! I'd be happy to! I'm so happy you made me a real mommy slut!" Erin giggles and gives you a quick hug before dropping to her knees and lapping up your sticky jizz with her tongue. You get down behind her and plug her pussy with your cock to keep any more cum from leaking out. Erin moans quietly as you gently fuck your jizzed semen even deeper inside her with your softening dick. Well, now what? You had a freshly bred 18 year old fuckslut on her knees, you can probably think of something.
