It was chaos. Olivia, as soon as she heard her sister scream, tried to get up from under my body and pushed me, and with my shorts over my heels I lost my balance and fell, taking two chairs with me and causing a huge noise. She then got up and tried to run out of the kitchen, as nonsense as it was, but Isabella took hold of her arm and prevented her from doing so, causing her to start to frantically cry. And, as such, in a few seconds, we went from heaven to hell, from a peaceful, lustful moment to a fucking mess, and the future looked even worse.
While I tried to regain at least some composure, Isabella said, even bossier than she normally was:
"Sit down on the table now, Both of you!"
I got up, my shorts still going back into place, and complied, while Olivia, still crying hard, dragged herself to one of the chairs and sat down, putting her head down onto the table. Once we were seated, Isabella made a theatrical movement and took Olivia's panties from the floor, throwing it on her sister and saying:
"You bitch! You always was' the prettier, the sweetest', the fucking 'mom's favorite', the 'poor one' that lost her father that she loved so much. Fuck you! I was fucking twelve when I had to change countries, leave all my friends, my life, the culture and language I was accustomed to, but it was you, the fucking six-year-old brat, that was 'sooo sad' that mom needed to give you all her attention and care, leaving me to fend for myself as I was 'almost an adult and so rational and pragmatic'... I took care of you, I was almost a mother to you while mom was away near all the time between her jobs and her fuck mates, and you never, ever gave me anything in return!"
I didn't have the faintest idea where all that was coming from. I never knew there was some spat between the two of them, but again I never really had any intimacy with Isabella and Olivia as, until recently - or until I fucked Olivia the night before -, Hellen was the only one I had a more close relationship with. But I wasn't worried about their spat, my main concern was with the consequences of what was happening, so I tried to keep my cool and said:
"Isabella, let's talk about it..."
"Talk about what, your cock buried inside this whore's cunt?"
"You don't need to talk about your sister like that..."
"Oh, no? You don't know anything, do you, you fucking..."
"Hey, hey, hey! Let's slow things down here!"
I was starting to be really annoyed with all that attitude, and I thought that maybe it was time to put things where they belong, so I continued:
"I never, ever treated you bad, Isabella. I can understand you're upset with what happened because of your mother, but it doesn't give you the right to..."
"Because of my mother? BECAUSE OF MY MOTHER??? That fucking whore, that for years and years left me at home to take care of this bitch here and Hellen while she fucked some guy in hotels or car seats??? FUCK HER!"
Now I was really confused and, not knowing what to say, I asked:
"But... But if your mother isn't the problem, then why..."
"Because she is jealous... of me."
It was Olivia, that had finally stopped to cry and, with puffed eyes, fitted Isabella with disdain.
"Jealous... of you?"
Each time someone tried to explain something to me I was more and more lost, so I simply stopped trying to understand and started asking.
"Yes. Isn't it true, you fucking lesbian?"
"I'm not a lesbian! I'm bisexual! And even if I was, what would be the problem?"
"None, if you haven't tried to have sex with... with your own sister, you freak!"
My jaw dropped and I asked, almost as a reflex:
"What???"
Olivia continued:
"Yes, Mark! Miss 'what the fuck are you doing' here tried to seduce me a few years ago, right after my twenty-year birthday party! I was a little drunk, and she started to get all touchy with me at my room while we were talking about the party, and suddenly she kissed me and put her hand on my..."
Olivia stopped talking, and Isabella's face was as red as it could be with rage and shame, but she didn't say anything, and all was quiet for a few seconds. I was still trying to allow all the information to sink in when, all of a sudden, Isabella said:
"You know what? I'll just tell everything to mom and to Tom, it's my duty to do so. This is what you said to me before you told mom what happened that night, wasn't it, you fucking snitch? That it was your fucking duty as a daughter? She was never the same with me again after that day, always trying to keep Hellen away from me as if I would do the same to her and telling me how sick I was for... for loving you!"
"I... I love you too, Isabella... But... But not like that, we are sisters, and we are both women..."
"You don't know a thing about love! I'll call mom right now!"
Isabella took her phone from her pocket, but before she could unblock it, I jumped from my chair and took it from her, saying:
"Hey, hey... Let's talk about it a minute..."
"There's nothing to talk about, Mark. Give me the fucking phone!"
"Calm down, Isabella... If you do this, you will destroy everyone's life, including mine and yours. I always treated you well, didn't I? And you, if you tell your mother this, she will never forgive you too, as she will always remember who destroyed her happiness. And, as you said yourself, she will side with Olivia in the end, her 'dearest', and all this for what?"
Isabella seemed to think about what I had just said, looking conflicted, and I took the opportunity to continue:
"Maybe we can... arrange something, so everyone is happy..."
"Like what? Money? I don't want your fucking money!"
"Honey, you know that I gave you all everything I can. Each of you have a car, an allowance - even with you working and not being asked to help with the house's costs - and a lot more. This is not about money."
"So what?"
"Maybe... Maybe Olivia could make it up to you..."
Olivia looked at me with wide eyes, but I continued:
"You said you love her... Well, I love her too, and I would hate to see her lose her mother's respect, and I believe you feel the same. But everyone could be happy if she would let you have what you want..."
"NO WAY!"
Olivia almost screamed and then added:
"I'll never, ever let her touch me, I'm not a fucking lesbian!"
"Bisexual!!"
"Girls, girls, stop! Olivia, let me be clear: it's that or letting your mother know about us. And, if this happens, the marriage is over and so is the house, car and everything, as your mother will not only leave but will never accept a dime from me, even if I want to help, and I would want to. I would be miserable, as I love your mother and you all very much, she would be destroyed, and you three would go back to the old life in a tiny room and with no money. On the other hand, if you relax and let your sister make you feel good, maybe you can even enjoy it..."
My crude description of a future without money and with her mother despising her had an effect, and Olivia looked conflicted, while Isabella, that until now hadn't give me the OK for my plan, jumped in:
"Oly... You know... You know how much I love you... I would never do anything to hurt you... Look, let's do the following: we do it once, and if you don't like it, if after really giving me a chance you don't want it anymore, it's ok. I... I will not tell mom about anything, even if after this one time you want me to stay away."
Olivia got up from the table and walked around, clearly fighting an internal battle to decide, while me and Isabella waited nervously. Finally, after what seemed to be an eternity, she looked at her sister and said, anger in her voice:
"Fine, but with one condition."
"What?"
"That... That mark is with us. So, I can feel more safe and can relax a little!"
My jaw dropped for the second time that day, and I could feel my heart pumping with the prospect of, a few minutes after thinking I was completely fucked, having two beautiful sisters in bed with me at the same time. Isabella, on the other hand, looked unsure but said in the end:
"O... Ok, but... But you will not touch me, Mark."
"Ok.. I think. So... Let me make it clear: we will be together, the three of us?"
I was still not believing my luck, so I needed to ask...
"Yes, but you will not touch me... unless I want you to."
Isabella was now leaving a door open, going from 'you will not touch me' to 'unless I want you to' in a minute. And that day, that had started like a nightmare, was turning fast into the most fantastic wet dream I ever had.
A few minutes after the conversation took place, Claudia and Hellen arrived to find us three talking normally in the kitchen, trying to act as if nothing had happened. My wife gave me a sexy kiss on the lips and, looking as she had had a few drinks while out, said to her daughters:
"Tell me girls, don't I have the sexiest husband?"
Everyone laughed, although not for the reason Claudia thought we did.

It took us two weeks to organize everything properly, as Olivia was adamant that she wouldn't allow it to happen inside the house. In this short period, I continued my routine of fucking Claudia a few times a week, Hellen sometimes at night when she sneaked out of her room to meet me on the couch, and Olivia only once, since she was too afraid of being caught again. At this point, nobody except Isabella knew what was happening, and even her knew only about Olivia, not Hellen.
