Your boyfriend gets out of bed. He wants to use the ring to swap his dick for another. You do not agree. You just started using it and want to keep playing with that big cock while it's there. But your boyfriend sticks to you to kiss you, whispering "Please...". At the same time, he grabs the ring between your legs. He inserts his dick in while dislodging your balls. His rod next to yours, he gently pulls out "your" cock from the ring while inserting his small balls into it. You let him do it. Finally, he whispers in your ear "Thank you".
Alexis rushes into the living room to take your phone. The StarDust app is still open. Alexis' goal is to give you the same strong orgasm you gave him. To do this, he writes the word "thick" and presses the "swap" button. Unfortunately, a message appears on the screen: "Error: swap already in progress"
"Babe, I got a problem!" he shouts towards the bedroom.
"Me too..." you say with a smile.
You stand at the living room's entrance. Alexis sees the big cock is still hanging between your legs even though you are no longer wearing the ring. The swap should have been cancelled. Yet there you are, wiggling your hips to shake the long, flaccid cock as it were yours.
You wonder how this is possible. You take the phone from your boyfriend's hands. You press the "help" button. You read the brief documentation to know out if there is a delay before the swap stops, or something like that... Result of your search: No, it's instantaneous. It shouldn't have happened.
Alexis takes your smartphone back to try to swap his dick once again. Unfortunately, the message "Error: swap already in progress" still appears. Looks like the ring no longer works. Disappointed, your boyfriend pulls it off his dick. At this moment a luminous flash occurs. Just like you, Alexis jumps because of the sharp pain he feels.
Without knowing why, the ring finally does his job and just replaced Alexis' member with a circumcised one. It's strange. It doesn't match the word "thick" he wrote in the app. Its flaccid size is bigger than Alexis' original dick but it's still low average. Alexis is a little disturbed no longer having foreskin. He examines "his" exposed head. As for the testicules, they are bigger and are hanging down.
You notice a familiar mole. You recognize this dick. It's yours! There is no doubt as soon as he's hard. Your boyfriend is shocked too. How could your dick have appeared on him?!
You and Alexis are shivering with excitement. Something unexpected just happened. Is there something wrong with the ring? Because at this time, none of you are wearing the ring. Yet, nice cocks that belonged to someone else minutes ago are now firmly embedded between your thighs as if there were yours.
You understand it's because of Alexis' little game. Earlier, the ring did not detect you were removing it because Alexis had inserted his dick in addition to yours. Doing this kept the link between the rings, except that Alexis became the wearer. He took your place in the swap, taking you and your 8 inches cock out of the equation.
It doesn't change his dick in any way. Except that by taking off the ring afterwards, Alexis initiated a swap cancellation. Causing a second swap, between Alexis and the other man who had been enjoying your 6 inches dick all this time.
In short, you've discovered a way to make permanent swaps. You are now endowed with an uncut 8 inches penis. And without wishing it, your boyfriend now owns your old 6 inches dick. He's not going to complain about it.
Thinking about it, you assume Alexis will never be able to get his original dick back. Unless you find the unlucky guy who made the exchange with you.
Thousands of miles away, the guy screams in horror. His 8 inches member didn't come back. It has been replaced by a 5,5 inches long dick. In other words, you stole his cock.
