Finely tooned (slutification)

The genie of love appeared in front of the couple, offering them one wish each. Jane knew what she wanted.

"I want to look more like my favorite character, Elsa, from Frozen."

"Granted, you will progressively become more like her."

Her boyfriend, though, had a different idea for his wish.

"I want a big cock that will turn boring romantics like her into real sluts."

"What?!" Jane shouted. "You ass..."

"Granted, as soon as she'll see your cock, she'll become more and more focused on pleasure."

"Don't grant that!" She complained.

But John had already taken out his one-foot-long cock, and as soon as she laid her eyes on it, she licked her lips. The genie was gone, and her body was already changing to look more like Elsa.

"You're such... such a horrible boyfriend! Making me attracted to your big... hard... wood..."

"Do you want it?"

"Fudge yes!"

Jane had any problem taking his massive dick in her pussy, it never felt that good, he was never that good in bed. If he was, she would have had sex more often. When he came, cum overflowed her pussy in white waves.

Things got trippy after that, the world started to get outlines, colors became more vibrant, and faces changed shape. His hands around her neck, he fucked her more and it felt even better. She was fucked like a bitch and loving it.

"Oooh, John! Take me! Go deep in me! I want to feel it all."

Their house turned into a castle, and hearts sprouted out of thin air, her mind was overwhelmed with pleasure. She loved his hands squeezing her neck and his cock destroying her pussy, she couldn't resist anymore, she was letting it go.

"Fuck me! Fuck me more!! I want your warm cum deep in me! Destroy my tight cold cunt!"

Jane was fully addicted to sex, and as a fairy tail princess she didn't have much to do except fucking in every room in the castle.

The realm turned into a sex addicted orgy where everyone was fucking everywhere, the story distorted by the slut mentality she adopted. John had a lot of mistresses, but she didn't care as long as he fulfilled his duty as a living sex toy for her.
