You want to fuck her

Any price is worth it, just to sink your naughty python into her bad wolf.

Rose Tyler smiles her toothy smile. "Did you ever have any choice?" she says. "From the moment we met, we both knew that this was inevitable." She walks over and plants a kiss on your lips, then bends over in front of you. "Don't you just love this ass of mine, though it'll be a part of the price you pay for fucking me." She starts to roll down her stockings, while your eyes stay fixated on that perfect peachy ass of hers. "Just to warn you, here's the price: I'm going to sit on you and fart in your face when we're finished."

You feel a sense of relief. As prices go, that's a bargain.

Rose stops bending over now, getting back to full height, arching her back, her breasts jutting forward, as her hands move to her bra strap. She looks down at your bulging erection. "I see that you can't wait for me to get out of these tight clothes, reveal my perfect body to you." Her hands move to her bra strap. "Me too."

She removes the bra slowly, teasingly, but finally she drops it to the ground, releasing her perfect breasts, more fulsome and magnificent than even you'd imagined. "Your eyes just can't resist this body," she says, as she removes her black panties, revealing her clean-shaven pussy. "Neither could mine, as poor Rose succumbed to all that vortex energy. I'm surprised I could even squeeze into her, but no need to maintain appearances anymore."

Your eyes pull back from that glorious pussy, and you notice that Rose now seems to be putting on some weight, her figure now resembling that of her mum Jackie.

"I can finally be myself," says whoever Rose is now, letting out a fart, her fingers moving to her forehead and opening her skin, a bright light shining from it. The next thing you know, a big green lumbering alien is stepping out of Rose's discarded skin.

The Slitheen stands before you, blinks and smiles. "So, lets get jiggy."
