Jeff, Erica's fiancé, is on the phone

It is my sister's phone. Someone is calling her while she was about to finally taste my cock.

I grab her phone from her purse and check who is interrupting us.

Jeff. Her damn fiancé.

"It is Jeff, Sis," I told her, showing her the name in the call.

"Ok, let me talk to him, and once I finish, I will continue...gagk."

"No, Sis," I interrupt her pressing her head against my crotch, forcing my cock inside her mouth. "Finish this first."

"Gagk...gagkk... Please...Gagk..gagk," She tries to plead with my cock still inside her.

"You can stop and talk to him first if you want."

"Thank you, Brother," She responds, alleviated, stopping sucking me.

"But if you talk with him without making me cum, you must tell him what you are doing right now. The truth."

She looks at me, then at the phone still ringing, and then at my hard cock, and realizes she doesn't have any choice. She lowers her head to savor my cock, on her own initiative. Once her mouth is working, I unhang the call.

"Don't swallow until I tell you," I command her just before picking up the phone.

"What's up," I finally answer, guiding my sister into my cock with my hands on her head.

"Who are you? Why are you answering Erica's phone?" Jeff ask me, confused.

"Oh, my. You are Jeff. Erica's fiancé. It is nice to talk to you finally."

"Sorry. I do not know your voice. Where is Erica?"

"Relax. Don't worry. She is not cheating on you with another man. I am Greg."

"Oh, Greg! Yes! Her brother! She has told me a lot about you," He continues, alleviated that the unknown man on his fiancé's phone is part of her family. If he knew my sister is already into ****, he would not be so relaxed.

"Yes. That's right. I am her brother. Nice to meet you."

"Can you put me with Erica?" He asks me again about my sister.

"She is not here right now," I told him while looking at my sister. She is indeed here, still sucking my cock with her gorgeous lips, trying not to moan, so he can't hear this scene. She is gentle but slow, not even taking my cock in the back of her throat once.

It is nice to receive my sister's blowjob, but I must train her more. She will learn how to use all of her throat to make it sloppy. I want to be able to ruin her face mask with her tears while she sucks me. But at least she is looking at me. Her eye contact is excellent. After all, I am not fucking any other whore's mouth; it is my sister's. I expect to see her eyes when I look at her doing this.

"Yeah, he was with me spending the afternoon, and she went downstairs to get something that she left in her car. I don't know why she is so slow. How clueless."

My sister takes the hint and increases the speed sucking me, still trying not to make any noise.

"Yeah, " Jeff agrees with me. "It happens to her a lot. She is a little forgetful."

"I am glad she hasn't changed. Even if in those small details, she SUCKS."

"Tell me, Greg. I assume you will come to our wedding."

"Oh, yeah," I answer him pressing my cock deep inside his fiance's mouth. "I can't wait to walk her down the aisle."

"She seems so happy now that you are reunited."

"Yeah, I wouldn't be anywhere but inside her..." I say, caressing my sister's face, bouncing up and down on my cock. "In her life, I mean."

Then he continues talking about himself and my sister, but I let him speak without interrupting him, paying more attention to the feeling of my sister's tongue playing with my cock.

"Are you there, Greg?" Jeff asks me, waking me from my reverie.

"Ehh...Yeah... Sorry...What were you saying?"

"She is taking so much to return."

"Yes, I do not what she is so SLOW... coff coff..." I pretend to cough to spit on my sister's face. "Sorry."

"It is ok. I can call her later."

"No...No... Wait... She is about to CUM..come...I think she is at the door... Wait a moment... I will... release...the door."

"Are you ok, Greg?"

I pull the phone away from my ear while squeezing my sister's head to keep it from moving away, at which point I finally come inside her. The hardest part is to bite my lips to avoid any moan escaping from my mouth.

"Hey, Jeff, still there?" I ask him.

"Yeah, did she finally return?"

"Yes, I pass you with her."

I grab my sister by the hair to move her mouth out of my cock while putting the phone close to her, with the speaker on so we both can talk.

"Heyy...Jeff...How are yo...doing...." She tries to talk with her mouth full of my cum.

"Lick me clean," I whisper to her so Jeff doesn't hear us.

"Yes...slurp...It is..slurp..." She tries to come up with an answer, licking me.

"You bought an ice cream, Sis?" I interrupt them. Maybe it is not ice, but she is indeed eating my cream.

"Haha..." Jeff laughs, " That is why it took you so much."

"Sorry...slurp..it is so hot...today...so I bought one after picking.. this from.. slurp..the car..."

"This is the surprise you wanted to show me, Sis?" I ask her.

"Yess...Is..Is..."

"Common, Erica, " Jeff adds, "I know what it is. You still haven't given the wedding invitation to your own brother?"

"Zorry..O forgo..." She tries to apologize, with her mouth still full of cum.

"Finish your ice cream, honey. I can understand you."

"Yeah, Sis. Swallow your cream," I command her.

She doesn't estate to do it. Once she knows I allow her, she closes her mouth and gulps everything down at once. She even opens her mouth and sticks out her tongue to show me it is empty. But for me, that is an invitation to spit a kiss inside her mouth.

"Ahhh," she moans, due to not expecting the spit. "It was so cold," she tries to remedy it, so Jeff thinks this is only about the ice cream.

"Haha, don't be so anxious, honey, take your time," he laughs, unaware of what his fiancé has actually ingested. "So, you have your invitation, Greg?"

"Finally is in my hands," I answer him, groping with my hands my sister's tits.

"Perfect, Greg. And Erica. I am sorry that we haven't been able to see each other lately. "

"It is ok, honey. I know you were out of town due to work, but don't worry, we will have so much time after our wedding."

"This is what I wanted to ask you. Tonight I am in town, but I must leave again tomorrow morning. I was thinking of having dinner with you."

"Jeff.." my sister tries to respond, looking at me to know what I wanted to say. "You should have told me this morning about this," She protest once she realizes, looking at my face, that I won't let her have dinner with him.

"I am sorry, honey. I suppose you are busy with your brother today."

"Sorry, man," I interrupt them. "I have already prepared dinner for the two of us" I give him a half-lie. There is indeed a dinner read for us, but the one who has cooked was my maid, Binita.

"Don't worry, Greg. It is good that she spends time with you, her family. I know it is in good hands."

"Excellent hands," I ironically agree with him, with my hands continuing to grope my sister.

"Another time, we will eat all three together. I need to hang up now. Love you, Erica."

"Next time, we will do it. Bye, honey," My sister says goodbye to him.

"Nice to meet you, Greg. Take care of her tonight." Jeff tells me.

"Oh, I will, Jeff. I will. Nice to meet you too. Bye."

I finally hang up the phone. My sister looks at me, angry, but no matter how much she tries, a naked woman with her hands behind her back doesn't look any menacing.

"You are so mean, Brother."

"Relax, Sis. There is nothing to worry about."

"What if he realizes what we were doing?" She asks me, frightened.

"With another man, maybe. He could be suspicious," I try to calm her fear, " but you are with your little brother, remember? I am the last man in the world he would believe you could be sexually involved with."

"Yeah, no sane man would believe that I am the sexual **** of my little brother."

"Exactly, Sis. So don't worry about the cuck."

"His name is Jeff," She corrects me.

"No, Sis. When we are alone or with my girls, his name is cuck, understand?"

She doesn't answer but knows she can't defy my orders.

"You will add to your mantra the following text."

I write a few phrases on her phone and turn on the record on her phone and let her read it while rubbing her cunt with my fingers.

"I will marry a cuck...ahh... that I won't fuck because my...ahh... holes are reserved for my brother. I will be sexually involved...ahh... with my brother ...while making my cuck...ahh... be unaware... of it. I love talking with my... cuck at the same time... that my brother is fucking me...ahh... with him being oblivious to everything...yes!... ."

Her mantra is perfect, as always. With this, she won't feel remorse for her cuck. It will make her horney, instead.

"Who has called you right now?" I ask her, putting into practice my new command.

"My... cuck, brother," She answers, accepting it.

"Perfect, Sis. Are you hungry, Sis? I think Binita has prepared a delicious dinner for us."
