You get dressed. The arousal finally subsided. But you feel a bit guilty having cheated on your boyfriend. It doesn't matter as long as Alexis doesn't find out. Jealous as he is, it would have a boring quarrel.
Daryl has a smile on his face. He missed getting fuck by a big cock. He hesitates, then he asks if his boyfriend can use the cock ring. Daryl tells you that he is the man of his life, but unfortunately, he has one flaw. You will happily help him.
Ruben arrives fifteen minutes later and Daryl makes introductions. His boyfriend is a handsome guy from Belgium. Tall, muscular and pale-skinned. He's really hot. Daryl tells him about the temporary swap penis cockring, and that it could become permanent.
Ruben doesn't like his dick. It is about 5 inches (13 cm) long, thin and suffering from severe phimosis. He never dared to be circumcised but he often thinks about it. The opportunity to change his dick is a great enthusiasm and he wants to try it.
You take the cockring out of your coat's inside pocket. Ruben pulls down his pants and slips it behind his dick and balls. A slight apprehension seizes him and prevents him from getting hard. You reassure him and ask him what type of cock he would like to have.
"8 inches at least!" interrupts the impatient Daryl
"Let me think about it!" replies Ruben laughing
Different measurements run through Ruben's head. Can he really ask what he wants? And since he's using this amazing object, why not try... a phimosis-free, thick, uncut black cock?
This bold request surprises you. You don't even know if it's possible. Especially since you can write only one word to the app. You think and it clicks in your brain. You simply write "BBC" and press the exchange button. You and Daryl watch at Ruben but nothing happens... The app shows a spinning circle with the "Searching..." text. A minute passes, then two minutes. You knew it couldn't work.
Ruben suddenly jumps and screams. You then see a long black penis, approximately 6 inches (15 cm), hanging between his legs. Yes, it's soft still. There are also two very big balls swinging behind it.
"Oh my god, my god!" says Ruben, his cheeks turn red.
You look at him with your mouth wide open. Ruben grabs the black cock held by the ring and can't believe he is feeling his fingers touch it. It's starting to harden. The shlong straightens up, widens and lengthens. Ruben presses it against his stomach and see that it goes beyond his navel. 9 inches (23 cm)! 9 fucking inches. A real massive black cock stuck on this handsome man's white body. That's crazy!
It looks fake, but Ruben can now feel his both hands gripping the long shaft. He plays with the thin foreskin easily sliding over his new head. It's prodigious, he doesn't need to get cut anymore.
"I love it! Can you keep it for a while so we can play with it?" Daryl asks.
"Um, I don't know. I wished for this as a joke. But why not, it would be great if I could keep it for few days" Ruben replies
You ask him if he's serious. It's really weird. Ruben confirms what he just said.
Alright. You explain them the method to make the temporary exchange go permanent. The trick is for Daryl to take Ruben's original dick. Damn, Daryl didn't expect that. At first, he didn't want to use the ring on himself. Ruben encourages him to do so. You also try to convince him. Daryl could make a small temporary sacrifice so Ruben could keep that big cock for few days. Daryl finally accepts.
We must act quickly before the black man who owns this junk interrupts the exchange. You guide Daryl to insert his cock into the ring. Alas it doesn't fit. The large black cock takes up all the space. So, you have to wait for Ruben to soften. To do so, he reads the war news on his smartphone. It only took him two minutes to soften.
Daryl moves closer against his boyfriend and gently inserts his semi-hard penis, then his balls. Then Ruben pulls slowly. He pulls his big package out of the ring with difficulty. Then he takes a step back with the long black cock still attached to his pubes. He did it! You have a hard time realizing that a white guy now owns a Big Black Cock. It's unreal! Then you see Ruben waiting for your confirmation.
"Yes, it's yours now" you stammer.
Daryl gets on his knees to take a closer look at the connection between Ruben and the BBC. You also get closer to see his skin clearly change from white to black, like a graft, but without scars.
It's Daryl's turn to let out a little yelp of surprise. A sharp pain was felt down below. He stands up to find his above average sized cock replaced by Ruben's smaller one. He pulls his new skin with two fingers. The disconcerting sensation of no longer being able to pull back the foreskin struck him. He takes off the cockring, hoping this may cancel the exchange. But Ruben's dick remains between his thighs. Daryl grabs the balls and the base of the dick in his hand. He pulls hard and shakes it to make sure it is real. By doing this, he feels how deeply Ruben's dick is implanted inside him; and undoubtedly become HIS dick. As he feared, this change heavily impacts him. He already misses his nice cock.
Ruben bursts out laughing as he sees his former dick now attached to Daryl. It's so funny.
"Wait, wait! Daryl's white cock is now attached to the unlucky black man who gave me his BBC? Ha ha!" laughs Ruben
Daryl doesn't laugh. He hits Ruben's shoulder with his fist.
"What do we do next?" Daryl asks, turning to you.
You tell him he can change to another cock if Ruben's one bothers him. To do this, you have to start the exchange procedure again, but this requires a third man participation in order to trick the cockring and steal another cock.
That's right, Daryl is embarrassed having Ruben's phimosis dick. He would really like to take another, more normal one. He and Ruben are looking for someone they can trust in and who may be available now. Unfortunately, the peoples they are thinking of either don't answer the phone or are away from here. Daryl then asks you to be the third man. You have to refuse because you don't want to lose the beautiful big cock you found. Daryl is very disappointed but understands your decision.
Too bad for Daryl. But is it really that bad? He is the couple's bottom one, after all. He'll keep Ruben's dick for now. They are going to have fun with Ruben's new Big Black Cock for few days. When they've had enough, you will bring back the cockring so that both can take a new big cock, and why not, keep it forever. On that day, they will need to find a third person who will be used as a receiver in order to make the exchanges permanents.
