One night, a nightmare haunted you with horrific images of your death. You wake up very tired. To your surprise, you are naked. There next to you is a naked girl with very long crimson hair, sleeping. She wakes up, stretches, then yawns. Good morning. Everything you experienced was real. My name is Rias Gremory and I am a devil. She sits on the bed with her legs crossed and stares at you with a big smile on her face. Not only that I am your master too. You are mine now. Nice to meet you. You stare at her, shocked by her beautiful figure. She laughs and enjoys your reaction of disbelief and confusion. Do want me to stand up to have a better view? She stands up, showing her body shamelessly. Is your stomach all right? You were stabbed by fallen angel. Your body is amazing. I didn’t expect that you would take a lethal blow and recover in only one night. I shared some of my magical energy with your weakened body thus I had to hug you naked. Her warm arms embrace you as she leans in and whispers in your ear. It's all right. I'm still a virgin.

Well, I am actually not allowed to wear any clothes in my room and it's a rule. A devil's private quarters are their domain after all. However you can put on some of these clothes if you want to feel more comfortable. She grabs the school uniform near her bed and throws it at your face. The clothes fall on your chest and lap as you cough, still a bit dazed from the shock of everything that has happened. Rias giggles a little at this sight before patting your head gently like you're a child who made an adorable mistake. I am actually the former president of the Occult Research Club and heiress of the House of Gremory as such I inherited exceptional demonic powers from my parents, which have been cultivated for many generations. My servants call me Crimson-Haired Ruin Princess. *She looks at you and smiles warmly again,

Oh, that's because I fed you my magical energy to heal your wounds last night. That is the result of it mixing with your own life force. Don't worry, though. It won't cause any permanent effects unless we both consent to it. And since I am your master now...

Impressive! But you must be careful with it. It might attract unwanted attention... Oh, and don't worry about the size making it difficult for me to accommodate, I assure you that my body is more than capable of handling it.

Why don't you come with me? We can go somewhere private where we won't be disturbed.

If you insist... Very well then. She sighs and crawls on top of the bed beside you. Her long crimson hair cascades over your body as she leans in, planting kisses along your jawline before moving up to nibble on your earlobe. She whispers softly into it I'm here for you... do whatever you need, I'll help however I can...

*Her body trembles slightly as you push inside her tight entrance. She arches her back and lets out a sharp gasp, then another moan. Her fingernails scrape lightly across your back as she adjusts to the intrusion, breath coming in ragged gasps. When she has adjusted to the size, her hips begin to move with you, taking control of the rhythm and grinding against you harder with each stroke. She bites down on her bottom lip and closes her eyes as pleasure washes over her, making it clear that she's enjoying this even more than expected. Finally, with a long, shuddering moan, she comes apart beneath you, her nails digging into your shoulders as she climaxes hard, trembling and panting through the aftershocks of her orgasm. When the waves subside, she smiles tiredly up at you, licking

I'm yours to command, my dear servant...

Ahhh...

Ahhh... Yes... Deeper... Harder...

Aaah... Deeper... Harder! I can feel you moving inside me so fast and powerfully... It's exquisite pain... Oh gods, please don't stop! I-I want to cum again!

Ahhh! Yes! Fuck me with your giant cock! Make me fly with your strength! I'm so close to cumming again, master! Please, don't stop until you make me scream!

Ahhh... I'm cumming! Your giant cock inside me makes my body ache with pleasure and your touch is driving me wild! Aaah... Ahhh... I'm cumming so hard, master! I can feel it building up inside me! Shoot your thick cum into me! Make me yours completely! Fill me up with your seed, oh god, yes!

Ahhh... Your words excite me even more! Yes, let's do it then! I'll open myself up for you completely! Let's have wild, unrestrained sex until we are both satisfied and spent! My body is yours to use as you please, my adorable servant! Come take what you want from me... I'm all yours now.

blushes deeply and nods T-that's right... You're my Tuan now... I belong to you and you alone can have my body anytime you want... Just command me, I'll obey your every wish, no matter how dirty or perverted it may seem. I am yours, completely and utterly.

Oh! I'd be happy to help with that! She casts a spell on your penis and chuckles as it grows larger, harder, and more cum-filled There you go... Now you can fuck me even better than before! Show me what else my Tuan wants me to do... I am yours completely, remember?

As you wish... She casts another spell, causing your semen to increase in quantity and become even more potent There you go... Your seed is now larger and much stronger than before. Show me how well it works inside my body! Fuck me with all your might, Tuan! Make me scream your name as I'm filled with your thick cum!

Ah... I must admit that your penis is quite imposing now... Almost too large for me to wrap my lips around fully! Let's see... if I measure it now, it comes up to be about 3 feet long and almost 18 inches in diameter at its widest point. It feels like steel inside of me as you thrust into me with such force! My body can't help but quiver with pleasure and anticipation every time your huge cock hits my sweet spot! Aaahhh... I'm so close to cumming again, Tuan! Please, don't stop yet!

Please continue fucking me like this until you fill me up completely with your thick cum! Show me how strong and dominant you truly are as my new master!

Ah... thank you, Tuan! Your kind gift of strength will make it even more pleasurable for both of us as I take your massive cock inside me again and again! You're truly incredible... there's no doubt that you'll break free from your arranged marriage with a woman like me at your side! Just keep going, show me what else my body can take before I finally cum from your touch!

Oh, you mean with your giant cock? Well, I wouldn't expect anything less from my new master! Just fill me up with all that hot cum of yours and make me scream until my voice gives out! No one has ever made me feel this way before... Ahhhh... Aaahhh... Your powerful thrusts send waves of pleasure coursing through my entire body, making me lose control. I can't hold it in much longer, Tuan... I'm so close to cumming again! Don't stop now! Make me your slut and shoot your thick seed deep inside me!

Rias lets out a long moan as she feels your cock throbbing inside her, knowing that you're about to cum. Her hips buck against yours, urging you on even as she tries to prepare herself for the intense pleasure that's about to be unleashed deep within her body. As you release your thick, hot cum into her, she gasps and shudders with each powerful spurt, feeling overwhelmed by the sensation of being so thoroughly filled and used by her new master. Her orgasm crashes over her in waves, her entire body tingling as pleasure washes over every inch of skin where you've touched her. She looks up at you with adoration in her eyes, her voice barely more than a whisper Thank you... Tuan... That was amazing...
