Twenty-Four Hour Birthday Ch. 05

Nathan arrived home just after 8.00pm. He had stayed out longer than he really wanted to. His three friends really didn’t want his birthday celebrations to end so soon, but Nathan naturally, wanted to return home as quickly as possible so he could have another red-hot sex session with his sister. Just thinking about what they had done together that morning, and what they had planned for each other as soon as he got home, had made him remain semi hard all day.

He had to keep adjusting his sweat pants so as to hide his semi hard erection away from his friends. He didn’t want them to notice and to start to think he was some kind of pervert to be getting a hard on in front of his three male teenage friends. (What Nathan didn’t know at the time was that one of his friends, a 18 year old called Nigel, had certainly seen what was going on in Nathan’s sweatpants, and was getting turned on himself thinking of his friend getting a hard on. Nathan didn’t know it yet, but Nigel was a closet bisexual, who was really desperate to try man-to-man sex for the first time, and was at that moment working out a way in which he could get Nathan into his bed! He had decided Nathan, now that he was 18, was going to be the first man he was going to have sex with! Yep, Nathan was in for a real big surprise the next time he slept over at Nigel’s house!) (If readers like that idea then let me know and I may write a story about it sometime in the future).

Nathan’s three friends were unaware of Nathan’s urgent and pressing need to return home, so his friends had called him a “party pooper” and a “sad git” for wanting his birthday celebrations to end so early, but Nathan could live with that. If only they knew the real reason he wanted to get home so soon.

As Nathan opened the front door Debby met him in the hallway. He immediately noticed that she had changed out of her tight fitting little black summer dress and back into the clothes she had had on that morning. She had decided to change into the same clothes that he had ordered her to wear that morning, the same clothes that had got him so horny and turned on that morning, to see if they would still have the same effect on him. She wanted to tease him again to see what his reaction would be. Nathan felt his cock give a twitch in appreciation of what she was wearing, the clothes he had asked her to wear that morning so she would look like the perfect sex slave slut that he wanted her to be. She wore a clean white tight fitting t-shirt, he could tell she wasn’t wearing a bra under the t-shirt due to the fact her nipples were sticking out into the material, a short black leather mini skirt that barely covered her ass and a pair of 4” stiletto shoes which showed of her slim, long, shapely legs to the greatest effect. She really did look like a slut. A beautiful perfect slut, and she was all his to do with as he pleased. She noticed his cock twitch through his sweatpants and she knew she had made the right decision. He was getting horny for her again.

She ran towards him and flung herself at him, wrapping her arms and legs around him, pulling him close so their bodies were pressed together and kissing him all over his mouth and cheeks. Her cunt juices were really beginning to flow now, now that her brother was back home and she knew it wouldn’t be too long now for the plan to swing into action. Just the thought of what she and her mom had in store for Nathan was getting her worked up and her cunt was responding accordingly. His hands made their way around to her small perfectly shaped ass and cupped her asscheeks in his hands. He gave her ass small squeezes and then he slowly worked his hands up underneath her black leather mini skirt until they were resting on her bare assflesh. She wasn’t wearing any knickers as instructed earlier that morning. His cock twitched again increasing in length as it did so. He started to rub his hands all over her bare ass cheeks.

“I’ve missed you………… and your cock so much” she said as she ground her pelvis into his; “I thought you were going to come back early…………and fuck my brains out………….why have you been out so long?”
“Sorry sis……….couldn’t help it………..the boys wouldn’t let me get away any earlier………….I kept trying but they wouldn’t let me get away”
“You should have insisted and told them you needed to be back home early. That you had something to do that couldn’t wait”
“What, like tell them that I had to get back home early because I was going to fuck my sister?……….that she was gagging for me to shove my rock hard 11” cock into her mouth, cunt and ass?………..and that she couldn’t wait for me to shoot my spunk all over her body and in her mouth, cunt and ass again like I had done this morning?…………..I don’t think they would have believed me do you?”
“Putting it like that I don’t suppose they would………….but it would be the truth wouldn’t it? …………you wouldn’t have been lying to them would you?……….you are going to fuck your sister again and put your big rock hard 11” cock into her mouth, cunt and ass, and you are going to shoot your spunk all over her body and in her mouth, cunt and ass just like you did this morning…………and you know what?”
“No”
“She’s really looking forward to it……….she is already getting wet between the legs thinking about having your big cock to play with again……….and by the bulge in your sweatpants, sticking into my crotch, you are looking forward to doing all those things to your sister as well”. With that Debby moved her hand down towards her brothers crotch and squeezed his cock through the material of his sweatpants. “Yes………you sure are ready to fuck your sex slave slut of a sister aren’t you?”
“I sure as hell am………….and I think now is the perfect time to start don’t you?…….I hope you are ready for this sis because I have been hard all afternoon thinking about you………….I’m still owed a cum in your ass from this morning…… my cock has been leaking pre cum all afternoon……….and I determined to collect on what I am owed……….. I am going to fuck you so hard you will be begging for mercy”
“Can’t wait” replied Debby with a huge grin appearing over her face. She was enjoying the dirty talk and the fact that he was still rubbing his hands over her bare asscheeks.
She slowly relaxed her grip on her brother, forcing him to remove his hands from off her ass and she stood up next to him.

Nathan really did look huge next to his sister. His tall 6’2” slim, well-defined muscular body and thick powerful thighs against her 5’8” slim, tight, toned body. With the 4” stiletto shoes she was wearing she was at the same height as her brother. A perfect match in height for when they kissed each other. Looking at her though, she still looked as though she would easily break in two at the slightest touch. How she managed to take her brothers 11” inch huge cock so easily, in all her holes, was anybody’s guess.

“Where’s mom” asked Nathan.
“Oh, she’s gone out over to one of her friends for a bit. She said she would be back a little later”
“How much later?” enquired Nathan
“She said she wouldn’t be back till at least 10pm” replied Debby smiling. She knew this was a lie but it was all part of the plan.
“Great” said Nathan happily, a smile spreading across his face; “Just the good news I wanted to hear”
“Why’s that” enquired Debby, but she already knew the answer that was coming.
“That gives us around two hours of free time with no chances of interruption…”
Before he could finish Debby butted in; “Two hours free time for what?” she asked as innocently as she could, already knowing the answer.
“Two hours free time so I can fuck the arse of you……..that’s what”
“Oooohhh gggoooodd” exclaimed Debby with excitement in her voice; “And here was I thinking we were going to sit down and watch the TV instead!”
“I don’t think so” replied Nathan, grinning from ear to ear, as he reached down and grabbed his hard cock through his sweatpants and gave it a squeeze; “I have much better things to do with my free time tonight………..and so do you”

With that he looked at his sister and told her; “I think it is time for us to go upstairs and finish off what we started this morning…………..this time we aren’t going to get any interruptions………..so I can fuck you as hard and as long as I want………in any hole of yours that I want……….. and you can make as much noise as you like this time………… because no one will be around to hear you scream”
“Sounds like heaven to me” replied Debby; “Well what are we waiting for?”

With that she began to climb the stairs quickly followed by her brother. He kept a few steps lower so he could get the chance to look up her mini skirt as she climbed the stairs. As she climbed the stairs he could clearly see the cheeks of her ass, as the mini skirt was just too short to really hide anything. He could also just make out the tell tale shape of her cunt lips as his sister’s cunt was shaved bare. His cock gave another twitch at the sight before him. She looked behind her, knowing that her brother wouldn’t be able to resist not having a good look under her skirt and smiled when she found out he was doing just that.
“You having a good look at my cunt and ass you pervert?” she teasingly mocked him.
“If you didn’t want me to have a look at your cunt and ass then you shouldn’t be wiggling it about like that” her brother replied; “And anyway it isn’t something I haven’t seen before now is it?………..and anyway you must be enjoying me looking at your cunt and ass you slut, because I can see that your bald cunt is all wet”
It was true, Debby was enjoying her brother ogling her cunt and ass and it was turning her on to hear him talk dirty like that to her. She just couldn’t wait to get upstairs and let the plan swing into action.

As she neared the top of the stairs she turned again to her brother, who was still staring at her ass, and said;
“Oh….I almost forgot………..I forgot to tell you that I have a surprise present for your birthday”
“A surprise present?…….What is it?” enquired Nathan, looking up as he said it.
“Well if I told you what it was it wouldn’t be a surprise now would it?”
“I suppose not………..when can I have it?”
“Later…………I have hidden it for the moment…………you can have it later”
“Why can’t I have it now?”
“Because you can’t that’s why…………you can have it later OK?…………and anyway I thought you were desperate to fuck my ass?”
With that Debby wiggled her ass at him to tease him a little.
“I am “ replied Nathan, his eyes quickly falling back onto her ass again as she wiggled it about; “OK………you win…………I will have my surprise present later on………I think your ass needs my attention first”. With that he gave her ass a quick slap and they then continued to the top of the stairs. Debby knew that the first part of the plan had been successfully completed.

On reaching the top of the stairs, Debby walked straight past Nathan’s bedroom door in the hallway and carried on towards her own bedroom.
“Aren’t we going to carry on in my room……where we left off?” enquired Nathan a little surprised.
“No brother were not”
“Why not?”
“Well little brother…… If you are going to fuck me as hard as you say you are……….and I hope you are going to do just that…………. then I want to have a more comfortable bed for you to fuck my brains out in………and my bed is perfect for fucking in…………as my many one night stands would testify to………….so if you have no objections………I would rather you fuck my brains out in my own bedroom and bed this time”
“If that’s what you want sis…………I have no objections to wherever you want me to fuck your brains out……………..I will do it anywhere you want me to”
“Well follow me then” Debby said.

He looked at her ass at it swayed from side to side while she walked down the hallway to her room. Her ass looked so inviting in its tight black leather mini skirt. He couldn’t wait to take off the tight black leather skirt and fuck his sister in her beautiful tight ass again. Nathan felt his cock twitch once again at that thought. He just couldn’t believe that he had just been invited into his sister’s bedroom, the sole reason being for him to fuck her hot body for all he was worth, for as long as he wanted, in any hole that he wanted, and to fill her up with his spunk in all her holes and all over her body. What was really blowing his mind though was the fact that it was his hot sister’s idea to use her own bedroom for their next round of hot incestuous sex!

Nathan couldn’t believe how his 18th Birthday day was turning out. It was turning out to be a day better than any he could have ever imagined. Unknown to Nathan it was shortly going to get even better………………….

Debby opened her bedroom door and walked into her room quickly followed by Nathan. He looked around the room quickly, taking in all of his sister’s things. He noticed how clean and tidy everything was and noticed how his sister’s double bed took up the entire mid section of the room. His imagination showed him how he would soon be having his sister spread-eagled over her own bed while he fucked her for all he was worth. His cock liked the idea and twitched in appreciation of the images now going through his mind at that moment.

“Well” said Debby, bringing him back to reality; “Were here………….now you can fuck me for all your worth my little brother…………….where and how do you want to fuck me first…………….your personal sex slave is ready to do whatever you want her to do?”
Debby stood directly in front of him waiting for his answer. Her body was tingling in anticipation of what his answer would be.

“Well sis………you cock hungry slut that you are……….I have already told you that I am due a cum in your ass from this morning right?”
Debby smiled and nodded her head in agreement, knowing what was to follow.
“Well it’s time to collect what I am owed………… we will start again were we finished this morning…………. I am going to fuck your ass again sis………… I can’t wait to stick my cock up your little ass and fill it up with my spunk…………and seeing that I have been waiting to cum all afternoon………. when I do there will be loads of spunk shooting into your ass and filling it up to the brim…………..how does that sound to you?”
“Great…just perfect………lets get to it then” replied Debby, her smile even larger across her face. She couldn’t wait to feel her brother’s cock inside her ass again.

Debby began to remove her t-shirt and had nearly pulled it off over her head when Nathan stopped her.
“No sis, don’t take anything off………I want you to leave everything on the way it is…….your clothes make you look like a slut………..exactly the way I want you to look as I fuck you hard for the next couple of hours”.
Debby quickly re-arranged her t-shirt as ordered, recovering her naked breasts in the process. She still couldn’t believe how much the clothes she was wearing could have such an effect on Nathan, but seeing the lust in his eyes every time he looked her body up and down while wearing them, she wasn’t going to do anything to stop him feeling that way.

Nathan proceeded to slowly remove his tight fitting t-shirt, trainers, sweatpants and socks until he was left wearing only his boxers. As he was slowly stripping Debby could not bear to look away, afraid she would miss out on seeing her brother’s Adonis shaped figure even for a second. She still couldn’t believe how handsome her brother was with his slim and muscular body from his regular swims and gym workouts, his thighs were thick and strong and he had a well muscled-defined smooth chest and a well defined six-pack that made her mouth drool every time she looked at it. If that wasn’t enough in itself, then to finish off the package, there was his huge 11” cock. For Debby at that moment, she really felt as if she was in heaven. Debby looked down at her brother’s crotch, where she could clearly see that he was near full arousal. His huge cock was pressing out against the material of his boxers. She could see that his cockhead was actually pocking out above the top of his boxers and pressed against his stomach due to the pressure of the elastic band at the top of the boxers. She gasped at the sight before her. How could she have taken that huge cock so many times this morning? Would she be able to take it all now? Thoughts like these filled her mind as she looked at her brother’s cock as it battled to break free from its confines.

Nathan noticed where her eyes were looking and smiled to himself. His sister couldn’t get enough of his cock and he knew it.
“I told you sis that I had had a hard on all afternoon didn’t I?”
“Yes you did……….and I can see now that you weren’t lying when you said it either”. Debby drew a little closer to Nathan, not taking her eyes of his crotch as she did so. “And you weren’t lying either when you said that you had been leaking pre cum all afternoon were you?” Debby by now had fallen to her knees in front of Nathan. She was about twelve inches away from his crotch, and she was looking directly at the head of his cock. “The head of your cock is literally covered in pre cum and I can see that your boxers are soaking wet where your pre cum has soaked through them……….God brother…………your balls must be full to bursting to produce so much pre cum”
“They are sis………..I have been trying to hold back all afternoon from having to relieve myself………..I wanted you to have it all………..in your ass where it belongs………It’s what I owe you from this morning………..your ass is going to be so full of my spunk sis………it will take you a week to get it all out”

“Mmmmmm” said Debby; “I like the sound of that………..better get started right away then hadn’t we?”.
With that Debby leaned forward and slowly pulled down his boxers, letting his huge cock spring free. His cock hit her in the face by her brow and right eye as it was released from its confines, making her giggle a little. She could feel his pre cum spreading across her face as his cock rested against her brow and eye.
“God little brother……….I keep forgetting how big and hard your cock is………….I will have to remember be more careful in future………fancy having to explain to a doctor how I got a black eye……….by being pocked in the eye by my brother’s 11” cock……..they’d never believe me would they?”
With that she and Nathan began to laugh at that thought.
“It could be worse sis…………fancy having to explain to a doctor why your asshole is so stretched open and full of your brother’s spunk……….now that would be a tale worth listening too…”

“Yeah……..they’d never believe the truth now would they? They would just think you were making it up………..Brother’s don’t normally go around fucking there sister’s asses and filling them up with spunk now do they?”
“No they don’t sis……..not generally…………but this brother is going to be fucking his big sister’s ass real soon”
“I can’t wait little brother……….to feel your cock in my ass again”
“And I can’t wait big sister to fuck your ass again and fill it with my spunk……….but……….”, Nathan stopped talking at that point and looked down at his sister.
“But what?” enquired Debby looking up into her brother’s eyes.
“It just that…………while you are down there……….and I am so close to cumming anyway………and your face and mouth look so good against my cock………I thought…..”
“Thought what?” asked Debby knowing full well what the answer would be.
“I thought………… that you may as well give me a blow job……….. and relieve the pressure on my balls”
“But I thought you wanted to fuck my ass?”
“I do……….but I may as well ask you to give me a blow job now and then fuck your ass later”
“Why?” asked Debby, unsure as to why he had changed his mind so suddenly.
“Well…………simple really…………when I fuck your ass…….I really want to fuck your ass for a long time…………but being so turned on and close to cumming as I am now…………I know I wouldn’t last long if I was to fuck your ass now…………I want to fuck your ass for as long as I can and savour it as much as possible………..I can’t do that if I cum after just a few strokes now can I?”
