My Current Masturbation Fantasy

I thought some of you might be interested in the fantasy I’ve been working on over the past month or so during my masturbation sessions…

~ ~ ~

My sister-in-law Beth comes over one day to visit, but I can tell there’s something on her mind. I don’t push and let her come around to whatever it is on her own as I serve tea and chit-chat with her with her about nothing. Beth is an attractive woman. I always thought my brother deserved someone a lot prettier, but I’m probably biased. She’s just a couple inches shorter than me, wears her dirty-blond hair straight, and keeps herself fit. Breasts are about the same size as mine, though she’s more prone to show off some cleavage than I am. My brother’s wife has me beat in the booty department, but (in my humble opinion) I’ve got the edge when it comes to legs.

She finally comes around to what’s on her mind.

“This will probably seem like a weird thing for me to ask you, but I wanted your advice on something. Something very…personal. And it has to stay just between us.”

She has my attention. “I’m listening.”

“It has to do with sex…with Nick.”

Beth and I had never shared “girl talk” about our husbands before. I’m dying to hear what kinds of kinky things my big brother gets up to with his nice but generally “boring” wife. “Okay. I think I can handle it. Go on.”

“He told me a few years ago that he has a fantasy about being with two women…in bed. You know…”

“I get it, Beth. I think most men have that fantasy in their top three.”

“I’ve never been crazy about the idea, although not because I’m not curious about what it would be like with another woman.” She’s having a hard time looking at me as she speaks about these intimate secrets. “I just didn’t think I could ever find someone I could trust.”

“I can see how that would be a tricky part of it all.”

“Right. So, Nick’s birthday is coming up, and I want to make his fantasy come true as his present this year.”

“Wow. Does he know yet?”

“I want it to be a surprise. But before I go any further, I wanted to see if you thought I should go through with it.”

“Why me? I’ve never had a threesome before.” I wonder briefly if she knows about my hidden online identity.

“No, but you’ve known Nick a lot longer than I have. Do you think a three-way is something he would really want to do? Or is it just a fantasy and nothing more?”

She really put me on the spot with that. I knew nothing about my brother when it came to sex. In my fantasies, he was open to a lot of things, but that was just in my mind. I’m tempted to tell her to give up on the idea, but I can’t resist encouraging her with the sole hope that she’ll share the details with me after it happens.

“I say go for it.” I notice her face become a mix of surprise and excitement.

“You mean it? You think it would be okay?”

“If it’s something you both want, then you should at least give it a try. If it works, great. If it doesn’t, just forget about it and move on.”

“And you don’t think I’m some kind of perverted slut for wanting this?”

“All guys fantasize about threesomes, all women fantasize about being with another woman.”

“Even you?” She seems a little too eager to hear my answer to that question.

“From time to time.” I try to turn the focus away from me. “Now you just have to find a woman you can trust.”

“I trust you.”

The words hang in the air for several long minutes. She can’t be saying what I think she’s saying.

“Beth…what are you…?”

“You see, Nick has another fantasy.” She goes back to fidgeting and avoiding direct eye contact. “He fantasizes about having sex with you.”

A frenzy of conflicting emotions well up inside me. It’s a dream come true, but scary at the same time. “He said that?”

Beth nods. “Last year for his birthday, I…I pretended to be you when we made love that night. He called me by your name, and I said things to him like I was you. It was the best sex we’d had since before Adam was born.”

I’m almost too blown away to talk. “Wait…all those outfits you’ve been borrowing over the past year…?”

She blushes at that, making her cheeks even redder than they already are. “So I could dress up like you. Sometimes I would do stripteases for him in your clothes, or sometimes he just wanted to do me in one of your dresses. He loves it. And so do I.”

“I don’t know what to say.”

“I want to give your brother the real thing for his birthday this year. I want him to have you.” She looks at me and bites her lip nervously. “I don’t even have to be involved if you don’t want, but I would at least like to watch.”

I try to process it all, but my rational side is numb while my libidinous side is going crazy. A chance to finally fuck my brother and not risk ruining his marriage has just been plopped in my lap.

“But what I really want is for it to be a full on threesome,” Beth continues with a sense of needy urgency. “I trust you more than anyone I know, and I think you’re sexy as hell. You have no idea how often I masturbate and think of being with you, Rachael.”

That makes up my mind.

“Yes.” I take my sister-in-law’s shaky hands in mine. “I’ll do it.”

Beth is in a pink teddy. Nick is blindfolded and moves haltingly as she leads him into the bedroom.

“What have you got planned this time?” he questions and sniffs the air. “Mmm…you got my sister’s perfume, didn’t you?” At this point Beth removes his shirt. “What else?” She undoes his pants and pulls them down.

I can see my brother’s hard-on in his boxer shorts. My tummy fills with butterflies.

“Did you manage to steal a pair of her dirty panties? You did, didn’t you?”

Beth shoot me a wink and shimmies down his underwear. I see my brother’s cock for the first time. All doubt leaves me and for the first time I’m one-hundred percent sure this was the right choice.

“Ready?” Beth checks with her husband, then pulls off the blindfold. “Happy birthday!”

He blinks and smiles big as he spots a naked lady on his bed. He blinks some more and as his vision clears the smile fades.

“Rachael?” He looks at Beth confused. “What…?”

“I told her everything,” Beth admits, stepping close and taking hold of his erection. “Your sister wants to play with us. She’s agreed to make your fantasy come true.”

He looks at me, unable to believe it. “Rachael…are you sure?”

Instead of answering, I open my legs, spreading them wide. The sight of my dripping pussy is all it takes to convince him.

“Get over here and fuck your horny sister’s cunt while I eat your slutty wife’s pussy.”

The two of them kiss, then Nick is on top of me. “I’ve been wanting this for so long.”

“Me, too,” I whisper back.

I cry out with unrestrained ecstasy as my brother fills me with his cock.

Beth has stripped out of her negligee and joins us on the bed. “That’s it, Nick, fuck your sister’s hot pussy. Give her what she’s always wanted.” I’m too distracted by my brother’s thick cock pushing deep into me over and over again to be able to enjoy watching Beth masturbate to the sight of our incestuous union. It’s everything I ever dreamed of and more.

“Can I cum inside you, Rachael? Please say yes.”

“Do it. I want your cum in my cunt, Nick. Give it to me!”

We both orgasm together, with Beth getting herself off along with us. We waste no time before switching into a new position. Beth lies down, I turn over and bury my face between her legs while my brother slides into me from behind. Ten minutes later we each get off again. I barely have time to catch my breath before I’m straddling my sister-in-law’s face and she’s sucking her husband’s cum out of my pussy. Nick watches and strokes himself while he fingers his wife’s cunt. That’s when I notice something.

Someone is peeking in from the doorway. It’s my nephew Adam. My instinct is to scream and cover up, but his mother’s mouth on my clit feels too good to stop. It soon becomes obvious that he’s jerking off as he watches his parents fucking and sucking his aunt. I quickly decide that I don’t care if he watches. In fact, I want him to watch. I love that he’s watching his mother suck me off and eat the two loads of his father’s semen that I have inside me. I cum on Beth’s mouth, then push my brother onto his back and mount his big cock. Beth gets on his face and the two of us make out while we each hump Nick. I wonder if Adam can see my asshole as I ride his dad’s prick.

Our threesome goes on for a couple more hours. Things slow down, but none of us wants it to end. I suck my brother to orgasm while his wife licks his balls. I don’t get much of a reward, but just being able to taste my brother’s sperm is enough for me. Beth and I eat each other out some more, and even grind our cunts together. I’m dying to tongue fuck my brother’s asshole, but I want to save that for the next time we play together. And I know there’s going to be a next time as long as my husband doesn’t find out what I’m doing.

Adam is no longer in the doorway. “I think we woke your son,” I say during a lull in the action. “He saw us.”

“Yeah, we should have warned you.” Nick kisses one of my nipples, cupping my other breast lovingly. “He’s been spying on us for a few months now. I was going to have a talk with him, but Beth wouldn’t let me.”

Beth pauses tickling her own clit for a moment before saying anything. “Nick noticed him first and told me. I was pissed, but then the next time he peeped on us while we were doing it I got so turned on it was insane. It’s so fucking hot knowing that my son is watching me get fucked.” She plunges two fingers into her well-used hole and begins masturbating. I quickly join her. It’s only a matter of seconds before my brother is stroking his half limp cock.

“I found some pictures of you in a bikini on Adam’s tablet, y’know,” my brother mentions as the three of us brought ourselves closer to our final orgasms of the night. “He’s been jerking off to fantasies about his sexy aunt.”

“Well, fantasies do sometimes come true.” I zero in on my sore clit and work it as fast as I can. “Doesn’t Adam have a birthday coming up soon…?”

~ ~ ~

It started out with the conversation between me and my sister-in-law. I was getting myself off just to the idea of her inviting me to be in a threesome with her and my brother. I was then able to get as far as me opening my legs for Nick. Damn, would that be fucking hot! Eventually, I was able to progress to the actual sex. The addition of my nephew only cropped up earlier this week for the first time. This was an unexpected development, but I think we all know where this fantasy is going next…

    That is one incredibly hot fantasy, my pussy was dripping as I was reading it. But why would I expect anything less from you!! I can’t wait to see where it leads with Adam. Now if only Beth had a daughter too!

  2. Rachel what a very hot fantasy. Really enjoyed it thoroughly. Look forward to seeing where your hot fantasy gose with Adam. I am sure I will enjoy it too like the way your dirty mind thinks. XXOO

  3. Well, while Adam was “wanking” and watching his family.fuck, I was “wanking” while I was reading your great story Rach.

    Maybe.you should use that word more often than jerking as it turns.you on so.much…..

    Another wonderful fantasy, beautifully written and highly erotic.
    I’m sure I can add it to my own fantasies but of course you might just be involved somewhere…….

  4. What a raunchy and moisture inducing story Rach, I hope you have had many a cum to those images and thoughts. The addition of Adam is so naughty, oh my you make me shiver! xxx

  5. This is so hot and erotic… and being from you, of course, well-written.

    Looking forward to more hot installments.

    Thanks for warming things up with the temps here in N.E. so cold!

  6. I love the snapshot aspect of the story! So quick and hot and dirty. And I love the “voyeur” witnessing the incest, first the sister-in-law and then the nephew. I’m working on a new very long story that is going to have that element to it. A mother watches her twin sons satisfy another woman and her daughter. All for Rachael and all for her dirty mind! And you all are invited as well.

  7. Rachael, I love you sharing your fantasies with us. Your creativity & writing skills make it even more exciting. I was hard thru-out the entire read. I’m just very curious….How old will Adam be on his next birthday?
