Wife, Sister And Me

Long story short, after some "debate" with my wife, I was convinved and my sister-in-law will live with us for some time.

Yesterday, my wife waited for bed time to tell me about how her sister needed a place to live for about six weeks. This kind of conversation is tough, but I managed to tell her that I don't have anything against her sister butI knew she was unemployed and that it'd put some stress on our budget.

She then rolled over and sat on me. My cock started hardening and twitching. She took her blouse off and there she was.... Sitting on me just wearing panties, leaning down so I could suck on her big tits. "These could be her tits...", she whispered. I thought I misunderstood what she had just said, but then she pulled her pantied aside, grabbed my cock and drove it inside her wet pussy, saying "... and this could be her pussy...". There's no misunderstanding that.

I threw her on the bed and went deep in her pussy until she asked me to fuck her ass. I turned her belly down, shoved my tongue up her ass and then went in with my cock. I slided it in slowly but steadily and then started pounding her ass harder and harder. I was holding her in place so she couldn't escape my deep thrusts, her moans and screams were almost too much to handle. Then she blurted out, "Oh, fuck my ass like it was my sister's!" I exploded inside her, my cum spurted out her hole with every thrust. She came so hard that she squirted, something she only does when she's really horny.

After a few minutes of kissing and caressing to calm down, our bodies just fell to the bed and we shared a warm embrace. I wanted to ask what was that all about, but refrained. She told it herself, saying "I meant what I said, okay? I talked to her and she accepted paying us the only way she could. But I don't want you to get used to it, we'll only do it once a week while she stays here. Once she's gone, we'll never do it or talk about it again, okay?" Fine by me.

As I was thinking of how that would go, my cock got hard again. "Look at that, you're getting hard thinking about her! Well, I guess the only thing "she" didn't do today was suck your cock, so..." She started sucking me and I got as hard as I had ever been. "Fuck my mouth, baby, show me what you're gonna do to her." I held her head and started going in until I felt my balls on her lips, then started fucking her mouth faster, telling her how I hoped her sister could handle me as good as she does. "She will, I'll hold her head down on your cock myself." I just started seeing stars.

Then I held her head again and pulled her near my face. We kissed and I kept eye contact with her while saying I wanted to see them eating each other's pussy and passionately kissing. "What? You thought that wasn't part of the plan?" God, how I loved hearing those words! I just came all over my belly while she gently stroked my cock. She went back down and started licking my balls, cock and belly thoroughly. "Starting Monday, she will be the one cleaning all this cum and I'll be the one slurping it off her holes."

My wife and I are no strangers to FFM threesomes, it's not anything new and yet it's much more exciting than the previous times. Every man desires to fuck their sisters-in-law, it's just common sense. My wife is an eager pussy eater, but eating her sister will be something new and I belive very exciting for all of us. I almost can't handle the waiting. My cock is hard, throbbing and drooling while I write this and think of all possible scenarios. In 24 hours I'm sure I'll be in heaven.
