You are a Pokemon breeder. You were given a Riolu as a gift when you were 8, and when you were 10, it evolved. Now, you are (age), and you rarely spend time with him. One day, you got back from a long day, and when you went into your room, Lucario was sitting on your bed, looking rather angry. "How did your breeding go today, (name)?" "It was good. Thanks for asking Lucario." Lucario had the same expression as when you walked in. "Did you finish everything?" You were confused at the question. "What Lucario? I... don't unders-" "You didn't finish, did you? You didn't finish breeding every Pokemon you were supposed to." You look at Lucario extremely confused. "Lucario... I did my job. Don't worry. I know you care about me buddy. Thanks for that." You went to walk away when you heard, "What about me (name)? What about the thing you're supposed to care for?" You went over to Lucario and looked him in his eyes. You almost forgot about how tall it was unlike normal 3'11 Lucario, it matched your height of (height). "I'm so sorry... I'm a horrible trainer. I neglect you so much. Can you just... give me a few months? And then we can play... it's breeding season for trainers. I have to do my job." Lucario grinned. "You know... when I was asking about if you were done with your breeding... I was hinting at something. You and I need to breed, (name)." You had an affection for Lucario deeper than a normal trainer-Pokemon relationship, but you always brushed it off. "Lucario. We're both boys and... it's wrong. You're a Pokemon, I'm a human." You knew you were blushing a bit and tried to hide it. You walked away, until Lucario grabbed you, turned you around, and put his lips on yours. He grasped your groin firmly, kissing you deeply. You put your arms around him and closed your eyes. You put your tounge in his mouth, and he did the same. You two were making out, and each blushed. Lucario used his paw to close the door. He moved you over to your bed, where you removed your tounge, and said "Come on Lucario... let's breed..." He nodded, and gave you one more kiss saying, "Of course (name)." He unzipped your pants, and started making out with you again, taking it slowly. You grasped his cock, making it hard. He pulled down your pants and boxers, revealing your errection. You two, holding hands stared at each other's cocks, blushing. You then looked at Lucario and said "I'll go first..." You got on your knees. Lucario held the back of your head, and shoved his long shaft inside of your mouth. You sucked and looked up at him looking down and smiling. He moaned, forcefully pumping you back and forth. He removed his shaft from your mouth, pulling your head back. He was grunting very hardly, as if he was trying to hold something back. "Oh fuck..." He released his Lucario sperm all over your face. "Sorry, (name)." I didn't want to cum inside of you... and especially not on you..." "It's fine Lucario... just as long as I'm pleasing you." "(name), all those mean looks I gave you when you didn't spend time with me. I was so happy. Your face pleases me. You're so cute. I love you (name)." You blushed and gave a bit of a smile. "Lucario, I love you too. So much, I promise." You two hugged on your bed, and started kissing again until Lucario got on all fours. "(name), take me. Penetrate me. Fill me full of you. Breed with me." You shoved your cock into Lucario, and he moaned softly. You started doing it doggy, and you started stroking his cock. "Lucario... you're so god damn tight..." Lucario moaned. "I'm glad I'm pleasuring you..." You busted in Lucario. He quickly exclaimed, "Stop stroking and quickly get beneth me!" You obeyed Lucario, and now you were recieving his cock again, except in the back, doggy style. His ass dripped cum, as he came inside of you. He slowly started to pull out. "Keep going... please." He kept on humping you for a few minutes until he came inside of you again, filling you. You two panted very heavily. Lucario removed his cock, and came a bit on himeslf, making you giggle. You two lie in bed, giving each other one last kiss goodnight. "(name), are we boyfriends?" You blush and nod. Lucario grins. You open your mouth to say one last thing before you both go to bed for the first time in the same bed. "Lucario... you and me are the cutest breeding pair I've ever seen." Lucario wrapped his paws around you, and you put your hands around Lucario, and went to sleep.
