You’re bent over the desk, uniform already torn to shreds as your lower body is exposed to the demon prince that mounts himself behind you. His large hands trail up your back, the tingling sensation of claws against your spine. You let out a gasp, trying to keep your breathing steady knowing what’s to come. Once his fingers reach your neck, he grasps you gently grinding his body against you so you can feel him harden. “Look at you...so eager and ready for me.” You whimper and press against him to signal that you were ready in fact. This would be your first time taking Lord Diavolo since you decided to stay in the program longer than expected at RAD, but it would be worth the wait. His other claw presses against your entrance, wet and covered in thick saliva as he teases you. He retracts the sharp end of his finger, inserting a single digit into you to prep your hole. “Oh wow, you’re sucking me right in. It seems...I have to make some adjustments.” You try to turn your head to get a peek at what he means, but the hand that’s on the back on your neck keeps you in place, your hands gripped on the edge of the desk and your legs barely touching the ground below. Something slides into you again, though it feels much different than the prince’s finger, a little bit larger but not by much. Did he insert two? You feel him adjust his position behind you, scooting up closer as whatever he had inside you shifted with him, your ass pressed against his hips completely. “Now, let me know when to stop...otherwise I’ll keep going.” You’re unsure of what he meant, until it hits you. The length inside you grows thicker, mimicking the size of three fingers in girth. You mewl, rutting your hips. You wanted more. “Again? Okay.” Now the size increases, about 4 fingers. Your walls clung around what you assumed what his cock, growing in increments to match your tolerance. Your mind swims trying to visualize if you’ve ever gotten a glimpse, maybe a hint of a dick print in his pants but nothing comes to mind. He calls your name, asking if you were okay. You cry out for more yet again. “Oh...” He chuckles as he grips your waist. “Let me know if it hurts.” The next size up fills you over compacity, what you guess is more than a fist (human wise) that stretches your needy hole as you drool on the desk. The perfect amount of pain with stimulation hitting your core was more than you could ask for. You plead for him to thrust, you arch your back and grind your hips more. Diavolo understands, placing both claws on your waist and deeply groans as he pulls back before thrusting back into you deeply. Your legs bounce and dangle like string as he picks up the pace, your moans helping him decide just how fast or slow he should go. The more you clench around him, the harder it gets for him to move. You tap out after a couple more thrusts, your orgasm causing you to curse out loud which makes the demon prince laugh in amusement. “I’m happy you enjoyed that. I hope you’re ready to see what all wouldn’t fit in you.” Your curiosity killed you, what did he mean by “what all wouldn’t fit?” Still coming down from the aftermath of being ravaged, he helps you flip over to your back, your eyes widening at the sight. He’s in his usual demon form, the four jet black wings and horns decorated with gold plating, and his royal outfit on display. But then, right between his legs are not one, but two massive cocks. You try to speak but he looks confused before looking down and smiles with a short laugh. “Oh, let me adjust really quick. This isn’t how I normally look.” You didn’t know what you were expecting, but both lengths expand and grow much larger than before, nearly reaching his knee as they bobbed and smacked gently against each other. Small scales and ridges adorned the sides, with fleshy nubs decorating the underside like how you’d see a Jacob’s Ladder piercing. He exhales with relief as if it took a lot to hold it in. “Ah, there we go.” He looks at you with a smirk and walks up to your trembling legs, seeing your arousal trail down from your sex and to your thighs. Without words, he presses the bottom cock against you, grinding so you can feel the nubs trace over your sensitive parts slowly. You waste no time by taking the other by hand and swirling your tongue across the large twitching head, making eye contact with him as his golden eyes gleam and his fangs bear followed by heavy breaths. You keep going, trying to stimulate him the best you can and it works to your favor. He growls, thrusting and rutting against you faster, his own claws splintering the wood in the desk threatening to break it into pieces. He keeps his eyes on you, right before you feel a tremble in the upper shaft. He closes his eyes and moans loudly, both cocks shooting out streams of cum on your body. You’ve never seen so much before, some of it plastering your face and hair with the majority completely covering your belly and chest. The leftover is around you on the desk. He looks up, panting and smiling at you with a look of worry. “I’m sorry about that. We made quite the mess didn’t we?” Though you know you’re in for a massive scolding by a certain demon, you care very little at this moment. Now that you knew about Lord Diavolo’s abilities to adapt his body to yours, it’s like you always figured. You’ve hit the peak of satisfaction by choosing him.
