F4M, Sister/Brother Incest

This is a fantasy post by an adult for adults.

In this story, an older sister and her younger brother named Michael are finally going to their first Comic-Con by themselves as adults and it is the one in San Diego. While the brother and sister expected that this was going to be a good time for some brother and sister time, they didn't expect to bond in a way quite like this.

Sister: What a flight, I love how we got upgraded to first class when the flight company informed the passengers that an elderly couple passed away the night before the flight and since we were the youngest in age gap and have the same last name helped as they thought we were a couple, they give us their seats. Also, it does not hurt that they thought it was our honeymoon by the way we were holding hands.

My brother, you didn't tell me who you are going to be this Comic-Con. A surprise, huh? Well, hopefully, we can find you that special someone on this trip. Your ex-girlfriend was so possessive over you, like everytime we done a double date with me and my boyfriend currently my fiance at the time and you and her or when it was just the three of us, she always give me a dirty look like if she was not looking, <starting to get hot and bothered by the end of this part, you feel pure orgasmic bliss, secretly, you want this moment, you want to fuck your own baby brother as this was turning you on.> I would kiss you like she never could imagine with our tongues wrestling as we will swap saliva when we were kissing. As I will moan with pure passion for how good your lips feel on mine. Then I will suck that huge, massive, cock in my mouth and suck it so well that I wish I could suck it every day of the week. Then when I am getting wet enough, I will ride that hard dick, and keep riding you deep inside me until I was pregnant with our baby inside my womb and making me a mommy and we will run away together as we would start our own family.

What? <Lose yourself for a moment and didn’t care what others think as your cheeks blush scarlet red.>That was her fantasy, I never imagined that I was getting pounded deep in my vagina as you spanked my ass from behind as I moan your name louder and louder. <laugh to yourself, back to normal> She was batshit crazy, brother I am glad you broke up with her. Besides she didn't deserve you because you were way too good for her, you always had to pay for everything when you guys were doing something fun. Thanks for paying for this trip as a wedding present before my fiance takes me away from you, brother. You have treated me really well especially when we were first class acting like a couple but in all seriousness, you are the best brother a sister can ask for. <give your brother a kiss on the cheek>

Ready to get this weekend started? Well, I know it is Wednesday because Comic-Con starts tomorrow.

<Car door open and after a few seconds later the door closes as sister walks to the hotel door and approaches the front desk>

Sister: Hello, we have a reservation room 609 under my name. <keyboard typing as you turn to your brother> Are you as exciting as I am for Comic-Con? It is going to be so amazing to see it in person. <The front desk person informs you that the hotel accidentally booked your room.>

Sister: What are we going to do? Every hotel is probably booked in every city nearby Comic-Con for the whole weekend. <As your brother brings you in tight to hug you as he puts his hand on your back when you are on the verge of tears. The front desk person tells you to give them a minute to see what they can do for you two. As you broke the hug.> I guess we should just go home and maybe next year, we can go to Comic-Con. You started looking for flights going back home to Milwaukee and I will get us an Uber back to the airport. <The front desk person tries to get your attention and eventually gets your brother's attention as your brother tells you the front desk person wants to talk to you.>

Sister: Yes, you got any good news for me and my …. < The front desk person informs you that they talked to management and they allowed us to give you and your partner (because they assume you and your brother were a couple and saw the ring on your left hand) into the hotel best suite free of charge. You will receive free room service and complimentary bottles of champagne for your entire stay as an apology for the hotel screwing this up.>

Sister: Well, lover, looks like we are going to be staying here in San Diego all weekend long in their best suite on the house. How does that sound my gorgeous, sweetest, most caring, boyfriend, I ever had in my entire life? <As you were going in for a kiss on the cheek, your brother turned his head as both of you touched each others’ lips and it was not a quick peck on the lips. It was a good passionate kiss like this was a ‘hidden feelings’ for each other kiss. As you two were kissing, you felt his hands on your ass, and you were getting turned on with his hands on your ass. You two continue you to make out for a good while. After the kiss was broken up, you pulled away and moan a little as your panties became a little wet after and was a little bit of embarrassed as you asked the hotel room person what floor you will be staying. They were stunned by how you two kissed; they lost their train of thought until you asked again. They had to regroup their thoughts and said the top of the building and handed you two room keys; someone will come in with a bottle of champagne in a bit, they informed you. Before you left, the front desk person said that you two make a cute couple.>

Sister: Thank you for the compliment, it means that I picked the right man to get married to as you looked at your brother in his eyes.

<As the elevator closes to lead you to your getaway paradise with your brother, you begin to giggle with your brother.>

Sister: Wow, again people think that we are a couple. <As you put your arms over his shoulder, you were acting like a couple as you rubs his nose with his.> I love you, <as you whisper the next part> baby brother. <Back to normal> By the way, you are a really good kisser, where on Earth did you learn how to kiss like that? It doesn't matter right now, I am so excited to check our room out.

<Lucky for you, pack not too much. Also that your brother, when planning this trip for the two of you, he got the bellhop to take care of your bigger luggage before you landed in San Diego. So, when you both got out of the elevator, your brother picks you up like two newlyweds moving into their new home as you were surprised and giddy on what was going on.>

Sister: You are so strong, what has gotten into you? <slaps him on the shoulder, as you open the room door. He puts you down, and the best suite was massive, nothing you ever saw with your two eyes in your whole entire life. When you walked in, you see a kitchen that was too of the line in applications with the latest technology. Then when you walked into the living room, it had the biggest television you ever saw and the most comfortable sofa you ever sat on. Afterward, you are in the bedroom as you saw, there was one bed but as you walked passed the bedroom, you saw a jacuzzi on the deck outside of the bedroom, with a patio and a huge area for a barbecue if you choose to do so. You ran into the room to tell your brother to tell him the news. As you hopped on your brother as you lock your legs around his waist like lovers do when they make out.>

Sister: Michael, can you believe there is a jacuzzi in our room? A full blown huge jacuzzi with wine cup holders and a place to put a bottle, so it can be chilled to perfection and a built-in television that is waterproof and a Blu-rays player to watch DVDs, Blu-rays, Netflix or Hulu if we wanted to. Also, a timer to lets us adjust how much time for the bubbles or when to get out of the jacuzzi. So, I hope you brought your swimming trunks, and leave the door open, so the person who is bringing the champagne to our room. I am going to change in the bathroom as you giggled your way to the bathroom.

When you were in the bathroom, the door accidentally kicked open because one of the windows was still opening by the previous people who were in that room. You saw your baby brother changing his clothes. You saw his dick and oh my goodness, it was bigger than your fiance’s cock, you thought to yourself. You never slept with your fiance but he sends you a dick picture one time when he was drunk. Then you got a naughty idea. As you walked into the bedroom.

Sister: Hey, bro, maybe we should go naked, it is not like we see each other without clothes before. Mom and dad used to let us bath together when we were younger. If you are okay with that, then let's get in the hot jacuzzi.

A few moments going by as you are now in the jacuzzi, your brother and you are talking about your favorite superhero. The person from the hotel dropped off the champagne bottle and put the wine glasses in the appropriate location. They left as soon as they want to respect the privacy of the two of you.

After a few drinks in, you are now a little drunk because the champagne bottle had a stronger alcohol level that you realized.

Sister: Hey sexy, pull me close and let's look at the stars. Mmm, you are so warm, and your dick is pressed against me. This is how I imagined being in my honeymoon, as I grid on your penis. You are so big, baby. You want to take my virginity, tonight? I know what we agree upon until after marriage, but I want you tonight.

<Turn to face your brother, as you put your arms around his neck and french kiss >

Sister: You kiss differently, have you been practicing with your pillow? Haha, just kidding, honey. Where were we? <continues to kiss him for a good while then you got an idea.> Sister: Let's go to the bedroom < as you both get out of the jacuzzi, you spank your brother In the ass, as you whisper in his ear. > This sexy ass is mine, all my mine, my future husband. <As he picked you up as you lock your legs around his waist as you giggle after you put your music, music starts to play>

Sister: Ready to do this for so long, I dreamed of fucking you since I lay my eyes on you. <Kisses start slow and then the kisses start with some tongue. Then your brother put his hands on your ass as you moan of approval.> You are my fantasy coming true with every kiss, every slight touch. Put me on the bed, so you can fuck me missionary. Oh my goodness, you feel amazing in my pussy. Like your penis fits in my tight pussy... like it was meant to be there.

<After he placed you on the bed, you two continue to rock the bed as your moans keeping getting louder and louder as both of you get closer and closer to cum. Now, you get so turned on that you are finally doing sex for the very first time and losing your virginity. After three minutes of rough sex, you told your lover.>

Sister: You want to cum? Cum in me, baby. I am ready to cum as well. Please give me that cum in my fertile pussy. I hope one day, I will become pregnant with our babies and they will be the most cutest babies. They will be our babies that we will love, the ones with our features, the ones that are our kids.

Give me that <You both reached orgasm and feels his warm cum inside your pussy. After all that, you feel amazing like you feel like this was true love.>

Baby, we should do that more often, maybe on the honeymoon, I will let you fuck me in my beautiful ass. <spanks it and moans on the touch.> Can we cuddle? We got a long day tomorrow, we got our whole day booked, so right now, we can’t possibly go another round until we are done in San Diego. As I can't wait to wake up in your arms and maybe get in some serious trouble <nibbling on his right ear and bite light as you Eskimo kiss him.> I want you to be the big spoon, so I can look at your sexy brown eyes and know that these eyes make my pussy wet every time they look at me. Good night, honey <as you hug his stomach with your legs, you put his dick inside your pussy as you are smiling and give him one more kiss>

And now. A tease for the second part of this story.
