She decides to use her fingers (big mistake)

As Johnny and Luna were making out, without thinking, Luna shoved her fingers up his ass and begin to finger fuck him. Johnny opened his mouth as he was about to say something, but Luna cut him off.

"You love being fingered in your asshole, don't you? It's more pleasurable than anything else."

Johnny's words were lost in a moan of bliss, as his body ached in pleasure from being fingered by Luna. His body squirmed, twisting back and forth as he moaned in unparalleled bliss. Finally, his eyes rolled upward, his body arched, and a load of cum shot out of his dick. He lay still in bed, stopping for minute to catch his breath. Luna extracted her fingers from his ass, but she was too in the moment to notice that the ring she had been wearing was now missing from her finger.

"Oh you're not done yet, sweetheart. Now it's my turn." She said.

She stood up and took off the strap on, followed by her panties. She then climbed on top of him and straddled her pussy over his face.

"Eat it."

Despite being tired and somewhat sore, Johnny stuck his tongue into her pussy and pleasured her with all the strength he had left. Luna, already so wet from the sex they had been having, began to feel a wave traveling throughout her body. Within 5 minutes, she came on his face, screaming in bliss. She climbed off his face, and lay next to him. Both of them lay still, breathing heavy, staring up at the ceiling. Johnny's once perfect makeup was now ruined, mascara and eyeliner streaming down his face.

"Holy fuck, that was probably the best sex I've ever had." Luna said.

Johnny, who was still breathing heavy, looked over at her. "Do you mean that?"

"Yes, I do!" Luna responded immediately. Suddenly, something felt wrong. She had meant it, didn't she? Of course she had. But she couldn't escape the feeling in her head that something was off.

"I think there's something in my ass. Maybe I can pull it out." Johnny said.

Suddenly, Luna realized with a sense of dread what had happened. The ring was still wedged up his ass. Trying to hide the panic in her voice, she said "It's ok! Maybe I can get it."

Johnny, possibly noticing her panic, said "What's wrong? Don't you trust me with the ring?"

"Of course I do, but I really really need it back."

"How come?"

"It's really important to me, it...it belonged to my mother." frantically trying to reach her finger into his ass to grab it.

Johnny grabbed her hand, stopping her. Now he was really suspicious. "Will you tell me the truth about the ring?"

Luna, without thinking, as if compelled to do so, blurted out "Whatever question you ask while wearing the ring becomes true. No, wait-"

"So if I told you I had huge DD boobs, would that be true?" Johnny asked as flesh surged forward, expanding rapidly until a nice pair of DD breasts sat on his chest.

"Yes, of course. Oh god, did you not have them before?"

"-And if I say you will always follow my orders, and that you have no control over me, would that be true?"

"Yes, but that ring is mine! You have to give it back now!" Luna shouted, but it was too late.

"The ring belongs to me, doesn't it? And you respect that?"

Luna stopped trying to grab the ring, realizing that it didn't belong to her. It belonged to Johnny, and there was nothing she could do about it.

A smile crept over Johnny's face.
