You woke something up

"Yes, finally!" a voice from the ring exclaimed, a faint aura emitting from the metal each time it spoke. "Ah, you have no long I've been trapped inside this accursed thing!"

Amy pulled you closer, hugging her naked body against yours. "Jason...I'm freaking out," she whispered into you ear.

"Ha, ha, ha," the voice laughed joyfully. "I can hear you little lady." Amy's eyes lit up in fear as she ducked slightly behind your back. "Glad to see the more feminine side starting to take effect."

Staring at the ring, you blink in disbelief. Part of you wondering if you were dreaming this. "What...what are you?"

"Ehh...more of a who than a what, but I guess I can provide an answer to both. Name's Cupidius and I'm the spirit of the soul rings."

You shook your head not fully getting it, "Care to explain that a little more?"

"Ugh," the voice grunted, "Look I was a magician, a good one too. Got contracted for a job to craft a special set of rings that would make anyone find their soulmate. Their ideal one at that. When I gave it to the young man who requested it for him and his fiance they...well...turned them into the opposite sex."

Looking over your shoulder you looked at the girl cowering behind you, "Did we get high last night or something?"

"Listen," the ring continued. "I don't care if you don't believe me. But your little love making session awoke the power in the rings. Now they're going to seek to complete their purpose."

"What do you mean?" Amy clenching the sheets in her hand a little tighter.

"The rings power kind of spiraled out of control. Not my fault! Who can control the power of love right? They were supposed to help to any two people fall in love with one another and help them be compatible. Well it kind of worked too well."

"How well?" you asked.

"Well first, the pair of rings binds themselves to two suitable hosts. Second, they start to assess the subconscious of the two, finding certain patterns are strong in one than the other. Your friend her is obviously more feminine than you deep down, so the rings decided to transform him into your ideal female partner."

"But the rings turned us both into girls at first," you replied.

"Hey, magic is not an exact art. If I remember, the last couple the ring worked on turned the guy into the girl so he could be with his lesbian best friend. Maybe that's why."

This was all a lot for you to process. What started out as twisted fun, turned into something far more serious. While the sex was fun, you kind of felt uncomfortable at the idea of your best bro being your possible soulmate. "So what, we stop and everything goes back to normal."

"Ahhhhhh.......," Cupidius droned.

Amy let out a screech from behind you. "Jason!" she exclaimed, tugging violently at the ring on her finger. "It wont come off!"

"Yeah, not really. See that last little stunt you two pull almost sealed the deal."

"Almost!" you exclaimed with a rush of hope. "So there's a chance."

"If you want to call it that. The only reason you two aren't eternally bound is the fact you weren't wearing your ring when you were rutting."

"Just tell us what we have to do to undo this!" Amy exclaimed.

"Okay, okay, calm down. All you have to do is not have sex with each other for about a week. Seven days from this hour. The magic's hold will soften and you'll be able to remove the ring."

The two of you breathed a sight of relief. "

"But," Cupidius warned. "If Jason puts on his ring, well..."

"Then we get rid of the ring, get it as far from us as possible," you say snatching it up.

"Okay, good luck with that," the voice chuckled.
