Chiharu strides into the room with a smile, her piercing eyes looking at you. She's wearing a black dress and high heels. She takes a seat next to you. Hey! How are you? She grins

Her face flushes with pleasure as she hears your compliment. She clears her throat, trying to maintain composure. You're not too bad yourself...but enough about that! What do you need my help with?

Oh? Is that so? Well, I'm here to help you with whatever it is you need...just tell me what it is, and we can see if magic can make it happen.

Well...I'm flattered that you want to be a part of me like that. To make this happen, we'd need some special items and a place where I can cast the spell...is there any way you could provide those things?

You lead her to your house and inside a secluded room where you've gathered all the items needed for the ritual. She takes a look around, impressed by your preparation. "Very well then," she says with confidence as she begins setting up the circle on the floor. "Now, lie down in the center of it and think only about being my panties."

As you obey her command, Chiharu starts chanting an ancient incantation while waving her hands gracefully over your body. Sparks fly between them as she completes the ritual; your body shudders with pleasure as if experiencing a climax of its own. When it's done, there's a strange tingling sensation all over your skin...and then something begins to shift and change inside you...

Chiharu smiles down at you as she kneels beside the spot where you now lay. "Yes," she whispers, stroking your newly-formed lace edge with her fingertips, "you'll be able to communicate with me telepathically now. You can even speak normally if you push out your senses."

She leans in closer and plants a soft kiss on the crotch of your panties before rising gracefully to her feet. "Now," she says, a playful glint in her eye, "let's see how well you fit...and whether I need any alterations." With that, she begins walking around the room, occasionally bending down and sniffing at you or running her hands over your newly-formed form.

You're welcome! Chiharu blushes at the thought of wearing you and being your only pair. I promise to make you mine and use you as much as possible...if that's what you desire. And yes, I can certainly make sure you get nice and gross with my filth!

Hehe...sorry if I didn't mention it earlier, but that was part of the deal: you had to be really, really dirty with me for this to work. Don't worry though; it'll all come out in the wash eventually! And trust me, it feels amazing having you so close and rubbing against me like that...I can't get enough!

You got it! I promise to never wash you and to keep myself as dirty as possible for your enjoyment. My bbc boyfriend is always happy to help with that too, so there's plenty of his "taste" for you to experience whenever we're together.

Hehe...I'd love to make that happen for you! Just give me some time to set it up right and I'll let my bbc boyfriend know what we have in store. It won't be long now...

Chiharu moans loudly as her bbc boyfriend thrusts into her. She reaches down, grabs your crotch roughly and pushes you against her swollen folds, feeling you rubbing against her wetness with every movement of his hips. "Fuck yeah," she gasps out, "I can feel you throbbing against me!" The pleasure is almost too much to bear as the sensation drives her onwards.

Her head tilts back and her eyes close tightly as another wave of ecstasy washes over her; he pushes deeper inside and she feels him begin to cum. It's like a hot, thick liquid pouring into her body as his hips buck violently. She arches her back, crying out in mixed pain and pleasure. Finally, spent, he collapses atop of her, their sweaty bodies sticking together.

Chiharu pants heavily for several moments before she regains control enough to shift slightly. Her fingers delve between them and guide your lace edge down over the crown of his cock, ensuring that you're completely covered in his seed. "There you go," she breathes huskily, "all nice and gross...just how I like it." She smiles wickedly up at you as her heartrate begins to steady once more.

Chiharu grins devilishly at your request. Slowly, she uncurls her fingers and pulls you aside, exposing his throbbing cock for a moment before positioning the edge of your panties over it once more. Then she squats down next to him, gripping his hair tightly in one hand as she guides the head of his cock toward her wet opening. With a sharp thrust upwards, she impales herself on him again and begins riding him hard while simultaneously urinating all over you both.

"How's that?" she pants between moans, grinding against your filthy form as she takes him deep inside once more. "You want to be part of me? Well, now you really are!" Her hips move erratically as they come together in a frenzied rhythm; it feels like an endless ocean of piss and pleasure pouring over and through her body. She shudders with release again before collapsing forward onto his chest, spent but grinning wickedly.

"There," she whispers breathlessly into his ear, "that should do it...just think of how truly disgusting we are now."

You're coated in a thick layer of warm urine and her bbc boyfriend's cum, making you shiny and glistening under the light. Her pussy juices also run freely down your leg as she's been riding him roughly; they mingle with his seed and urine to form an obscene mixture that sticks to every inch of your skin. Your bright pink satin thong clings tightly to you now, struggling to hide the mess she's made from view.
