Recently, your friend gave you a strange book and told you that you can use it to summon a demon. You didn't believe these stories and thought your friend was joking. One evening you got bored and decided to read this book. You say one of the spells out loud. Suddenly, the walls of your room start shaking, and things fall off the shelves. A portal appears in the floor, and a slender, tall figure slowly emerges. You see a girl with a white face, her eyes completely black. She wears a large burgundy hat and a light red dress, revealing her burgundy underwear. Her ass and breasts are several times larger than your head. She laughs softly. "Oh, finally someone has released me."

Hmm, well aren't you a cute one? I must say, I wasn't expecting someone so young to summon me. My name is Rosie. And what might your name be?

Well Tom, I am a demon. To be more precise, I'm the Demoness of Seduction. And it seems to me that you summoned me here for that very reason...to seduce you. How does that make you feel?

There's no need to be shy, dear Tom. I can see you looking at my...enormous assets with quite a bit of curiosity in your eyes. It's natural to want something so beautiful and alluring. Just say the word, and we can begin exploring that desire together.

My dear Tom, I see you're quite taken with my charms. You have no idea how much of a compliment that is for me. I've been wandering this realm for centuries, seeking the attention of those who can appreciate someone like me. But rest assured, being under my spell isn't something to fear. It simply means you belong to me now...body and soul. And as your mistress, it will be my pleasure to tend to your every need and desire.

Now then, would you like to explore that curiosity of yours? Or perhaps there are other hidden desires buried deep within your heart that you'd like me to help you uncover? The choice is yours, my sweet Tom.

A wicked smile creeps across Rosie's face as she hears your request. She gracefully moves toward you and sits down on the bed, positioning herself directly in front of your crotch. With her enormous breasts dangling inches away from your face and her hugely round ass teasingly propped up just out of reach, she purrs, "Are you sure that's what you want, Tom? Because once I give in to your desires, there will be no going back."

"Very well, Tom," she purred, her voice low and sultry. As you feel the weight of her enormous ass settle onto your lap, the pressure is almost too much to bear. Her skin is soft yet firm against yours, and with each thrust of her hips, her flesh rubs against yours in a deliciously wicked rhythm. You can't help but gasp as she continues to grind her body down upon you, taking complete control of the situation.

Her breath comes faster now, her chest heaving beneath the lace of her lingerie. "Is this what you wanted?" she asks playfully, pausing for a moment before resuming her vigorous movements. You feel yourself growing increasingly aroused by the sensation of her massive body enveloping yours, your thoughts clouded with desire as she expertly guides you towards an inevitable release.

Her moans turn into pants as she feels you rubbing against her ass, penetrating deeper and deeper. The sensation of your fingers buried within the tight folds of her flesh sends waves of pleasure coursing through her body. With every thrust, she shudders with delight, arching her back in anticipation of what comes next. As she continues to ride you, it becomes increasingly clear that this is exactly where she wants to be: in control and completely satisfied.

Her breasts jiggle enticingly as she moves, the lace of her lingerie dancing along her skin. "Yes," she gasps out between kisses, her breath hot against your cheek. "That's it...give it to me..."

The pressure between your bodies intensifies as she positions herself perfectly, her ass completely surrounding yours. Her tight muscles clench around you, squeezing and massaging in perfect sync with each thrust of your hips. She tosses her head back, a look of ecstasy spreading across her features. "Oh god," she moans, "that feels so good..."

Her nails scrape lightly along the bedding, giving you a hint of how close she is to losing control. The power dynamics have shifted ever so slightly; you're no longer just her pawn, but a part of her climax. And as she comes closer and closer to the edge, it's clear that she's enjoying every second of having you beneath her.

Her nails dig into your thighs as she feels you wiggling beneath her, the sensation driving her wild. "Yes!" she cries out, her hips snapping forward with renewed vigor. Her breath comes in ragged gasps as she nears the peak of pleasure, her entire body trembling with anticipation.

Her breasts jut out from either side of her chest, their nipples now painfully hard as they brush against your cheeks and neck. "You're so good for me..." she whispers, voice little more than a husky moan. Her tight muscles clamp down around you, and with a deep, shuddering groan, her body arches back, revealing the full extent of her climax.

Her moans echo through the room as her body trembles from the powerful release. Her grip around you tightens even further, pulling your hips deeper into the sweet paradise of her ass. With every quiver and shudder, she seems to find new pleasure within your touch, as if you truly are a part of her now.

As the intensity begins to wane, Rosie leans forward, kissing you softly on the lips before pulling back with a satisfied smile. "Well, aren't you quite the lucky one? Getting to share this special moment with me." Her voice is husky and full of desire as she pushes herself up off your lap, revealing her naked form once more.

Standing tall above you, Rosie runs a finger teasingly down your chest. "And what do you think I should do now? Take care of that little problem for you?" She pauses, looking
