Push it as far as you can

"We need more," you say.

Emma nods.

"What should we do?" she asks.

"Let’s use the video camera for a bit."

"Okay"

You turn on the video camera filming you topless sister.

"Why don't you start by saying how big my cock is and how much you love it and so on, you know to make Cory jealous."

"Cory, you're an asshole with a small dick and you will never get this again," Emma says and starts playing up for the camera, stroking her big breasts.

You move so your cock gets in the frame, pushing it towards your sister. Emma gets what you’re aiming for and she grabs a hold of your massive tool. She strokes it a few times and you can't help yourself but to let out a moan. It feels so good, just having her stroke your cock.

"My brother got a much bigger cock than you," your sister says. She probably didn't notice that she said brother, but you sure did and it made your cock twitch.

"I don't know if I can fit it in my mouth," Emma says, before she starts sucking on your cock, letting her tongue twirl around your cockhead.

"It tastes so much better than yours and just sucking on it makes me so wet."

The pleasure of her blow job is almost too much; her warm mouth around your cock is almost too much pleasure. She's only sucked on it for about a minute, but you’re almost ready to blow your wad. She lets your dick pop out of her mouth and gives it on last kiss. Emma looks up at you asking you if this is enough with her eyes. You shake your head.

"Remove your panties and masturbate a bit for the camera"

"Are you sure?" Your sister sounds a bit unsure.

"He needs to see what he's missing."

Your sister hesitates a bit, before she slides her thong down her long legs. Emma is now completely naked standing in front of you her brother. Your look is drawn to her completely bald pussy; the voluptuous body of your sister is almost too much to take in. You suddenly notice that your hand has started to stroke your rock hard cock. The image of your hot naked sister is something you will never forget.

"Oh wow," you let out.

She lies down on the bed and spreads her leg, moving her hand down to her beautiful pink pussy. Starts slowly, letting her hand move around her pussy, before she finally sticks a finger inside.

"You love my tight wet pussy don't you, the way it feels around your cock"

"You never could fill me up, with your small dick. I got a real dick now," your sister says.

She continues to stimulate herself, quickly moving two fingers in and out of her glistening pussy. Her other hand is running all over her body, but is mostly rubbing her amazing breasts, stimulating her hard nipples.

"Now I'm going to fuck a real cock, with a man that actually have a clue on how to please a woman."

Emma rubs her clit, while she motions you to stop filming. She probably thinks you got enough film, but your cock has been hard for the last thirty minutes or so, you can't stop now. Her pussy is clearly wet from her rubbing and your plan is to bury your cock inside your sister, one way or another. You move over to her with your cock in your hand, lining it up against Emma's cunt.

"What are you doing?" Emma whispers.

You lean over to her, making your cock touch her thighs. Your cock has never been closer to your sister’s wet cunt.

"Just the tip and we will be done," you whisper in her ear, as your cock slowly moves up her thighs.

"We can't..."

"Just the tip"

She looks at you with uncertainty. Just the tip is probably one of the oldest tricks in the book and you both know it. She opens her mouth.

"Okay, just the tip"

You nod. Lining up your cock against her wet entrance, letting it slide up and down her crevice. You can feel how wet she is, she might be just as horny as you are. Just thinking about what you're about to is sending shockwaves through your body.

"And then we will be done," Emma says looking you in the eyes.

She looks so beautiful; her face is a bit red from the excitement. You want to kiss her red lips, but you're afraid it might break the spell. Instead you continue sliding your cock against the outside of her pussy, lubing it up with her juices. You don't want this to end. On the other hand you can't wait anymore, the pleasure you get from rubbing your cock against her outer lips is amazing, but you know it will feel even greater inside.

You start to slowly push yourself inside her, feeling her warmth around your cock as you bury the tip inside her. You can feel how tight she is, the pressure of her inner walls against your penis glans is feeling amazing. You know this is as far as you promised you would go, but you can't stop know. You know that your sister is feeling it too; her pussy is overflowing with her own juices.

You look into her eyes, before you begin to push your rock hard rod further into her tight cunt, feeling her walls pressing against more and more of your cock.

"What are you doing?" Emma asks, but she doesn't do anything to stop you.

You can feel your sister pussy clench against your thick member. The inside of her feels amazing and you're not sure that you could pull out even if she asked you to. You are already on the verge of cumming, just from being inside her. You feel her pussy adjust to your size, before you start pulling out only to bury yourself deep inside her again.

"It feels too good," you say in an attempt to explain why you have started to thrust your cock in and out of her tight pussy.

You can't understand that Cory said it was loose, if it'd been any tighter it would have bit your cock off. You look at your sister wondering what she’s thinking.

"It’s okay John, I feel it too," Emma says; she really is your big sister comforting and protecting you even in a situation like this.

Knowing she wants is too only enhances your pleasure, it's like a weight fell off your shoulders. You don't how much longer you can last, your sister pussy feels better than anything you've ever experienced, you’re not sure if it's the taboo or that her pussy actually feels better.

Your breath becomes more ragged as you wildly thrust inside your sister. You can't stop yourself as you move your face down for a kiss. Your sister looks at you strangely, but she doesn't turn away. You forcefully puss your tongue inside her mouth, seeking out her tongue before she finally succumbs and joins you for a deep kiss. It is almost enough to put you over the edge. You break the kiss as you feel the tingling feeling in your cock.

"Oh god it's so big," Emma screams out.

You've been so focused on your pleasure, that it hits you with surprise than you feel your sister body start convulsing in a huge orgasm. Her pussy is gripping your cock harder than ever before. It's too much pleasure; you thrust one last time inside her, before you feel the pleasure well over you.

"Oh I'm cumming!"

You feel your sperm run through your cock, erupting deep inside your sister's pussy. You've never cummed so hard, you feel your whole body shaking as you continue to pump load after load inside her. You slowly pull out your cock of her amazingly tight pussy, shooting the two last loads onto her pussy, some of the cum even reaches her breast. You can't believe how hard you came; you look at your sister and judging by the satisfied grin on her face this won't be the last time you engage in incestuous activities. She looks so erotic and hit, you look down at her pussy and you can already see huge amounts of cum pouring out of her.

Fucking your sister might have both been the best and most stupid thing you've ever done. You don't know how you'll ever be able to stop. You feel completely spent as you finally collapse besides your sister. You try to snuggle up against her and giving her a kiss, but she brushes you away. She gets up from the bed and you can see your cum dropping down her leg.

"We shouldn't have done this," your big sister says.

She looks really troubled by guilt, you want to say something, but before you can she has already left the room. You hear the shower starting, but you're too tired to get up and you decide to wait until she's done to talk to her. You're surprised that you don't feel any guilt, on the other hand it was consensual sex between two willing adults, there's nothing wrong with that. You can't wait to explain that to her, you're just going to rest your eyes for a bit.

The next time you open your eyes again, it’s morning. You feel hangover and then it hits you. You had sex with your sister last night. You're in her bed, but she doesn't seem to be in it. You remember that you had the best sex of your life last night, but also the look of guilt on your sister. Just thinking about it is making you hard, although part of it might be your normal morning wood.

You need to talk to her, convince her that you did nothing wrong. You get up and a put on your boxers from last night and start venturing into the rest of her three room apartment. You don't find her; instead you find a note on the kitchen table.

................

Hi John! Last night was huge mistake, let’s forget it ever happened and move on with our lives. I'll be back later today and I'll expect you to be gone by then. I erased the video; the whole thing was a stupid idea to begin with. Don't tell anyone what happened or both our lives will be ruined.

/Love Emma

PS. I'm sorry, I never should have let it happen.
