"Shit...What we going to do?...If she comes upstairs and finds us like this... She will...She will...She will fucking kill us...Oh shit...What we going to do..." She blurted the words out quickly hoping that her brother would provide some answers to their problem. Her eyes told him the full horror of the situation they were now in.
"Hallo, anybody here?" they heard their mother say again from downstairs.
Fear gripped her body and for a split second she was unable to think or do anything to help alleviate the situation. All that she could think of is that there she was, stark naked (apart from stiletto shoes) in her brothers bedroom, squatting over his naked muscular sweat soaked body, she had her fingers pushed deep into her cunt masturbating herself, and she also had six inches of his 11 inch rock hard cock sticking into and stretching her ass and not only that, if that wasn't bad enough, they were both on the very edge of cumming.
Her head started to spin from the situation, a mixture of fear of being caught in that position and also from the fact she was desperate to cum. She desperately wanted to carry on fucking her brother's dick until she came and to make matters worse she could also feel his dick twitching inside her ass as he neared his own point of no return. All the teasing her brother had recently done, bringing her so close to cumming and then depriving her, not once but twice of her release, and now she was so close again and yet she knew in the situation she was now in, that she wasn't going to be allowed to cum yet again. She knew all it would take was a few more thrusts of her fingers into her cunt and a few more thrusts of his dick into her ass and she and he would be over the edge and would cum together. She seriously thought for a split second about carrying on as they were, ignoring the situation completely, and quickly getting to their joint cum and hoping that they wouldn't be discovered until after they had had time to recover and clean themselves up.
She knew though that that idea was a non-starter and that they would have to stop what they were doing and answer their mother. If they didn't she would no doubt come upstairs looking for them and eventually she would find them in her sons room fucking each other's brains out!
"Shit" she commented as she withdrew her fingers from her cunt and lifted herself up enough so her brother's dick slipped out of her ass; " I had better go and answer her before she comes upstairs looking for us...You won't believe how close I was to cumming then...Shit...Third time unlucky eh?
She made her way to the door and opened it slightly looking out to see if their mother was anywhere to be seen. She heard a noise downstairs and knew that for the moment they were safe.
"Hi Mom your home early. Anything the matter?" she said trying to sound as normal as possible.
"At last!" replied her mother; "A reply...It's about time...What you been doing up there Debby? It took you long enough to reply"
"Eeerrr... Nothing...why? I had some music on in my room and didn't here you that's all" replied Debby, her heart pounding hoping she sounded convincing.
"It figures" replied her mother; "Is Nathan up there as well?"
Debby looked back at her brother who was now standing up in the middle of the room facing her, his dick sticking out in front of him at full mast.
"Yes" she replied.
"Well what's he doing up there?"
"He's in his room and he's hard..." She looked down at his dick and with a smile spreading over her face she looked him in the eyes and carried on talking to her mother; "He's HARD..." She paused for a moment and then continued: "at work studying for some exam I think". She could barely contain her laughter at what she had just said to her mother. Her brother just looked at her with an open mouth not believing what his sister had just said.
"Well you tell him to finish what he is doing. I am just about to start lunch and I want you both downstairs in five minutes OK?"
"Ok mom I will tell him" with that she closed the door and walked back over to her brother a big sigh escaping her lips. They were safe for now.
"I can't believe what you just said to mom" said a startled Nathan.
"It just seemed the most obvious thing to say for some reason" she replied standing right in front of him so that they were about six inches apart.
She looked down at his dick sticking out from his body and put her hand around it.
"Pity we have only got five minutes. I still need to come so badly. I think you do too right?"
Nathan shook his head, his dick twitching in her fingers.
"Well it looks as though we will have to wait till later for us to get off doesn't it? We can't risk doing anything else yet, not with mom just downstairs". With that she released his dick and reached forward and kissed him quickly on the lips.
"I am going to have a quick shower and freshen up a bit". She turned to leave for the bedroom door and at the same time started picking up her discarded clothes from around the bedroom floor where they had landed this morning after being taken off. She turned and did one last quick scan of the bedroom as she reached the bedroom door. She was happy that she had got all her clothes and that no evidence of their morning of incestuous sex remained for anyone to find.
She opened the door and walked into the landing, on turning back to pull the door shut she noticed Nathan still standing in the middle of the room with his dick still sticking out in front of him.
"Hey brother, better get decent. Mom wants you downstairs in five minutes don't forget" with that her eyes dropped to his dick and added; "That's if you can get decent with your dick standing up like that! I'm glad I'm not the one who has got to try and get it back inside a pair of boxers!". With that she pulled the door shut and headed off down the landing to the bathroom.
She went into her bedroom first and placed the clothes she had retrieved from her brother's bedroom and put them in a pile on the floor next to her wardrobe. She then removed the 4" stiletto shoes she was wearing and placed them on the top of the clothes. She was now completely naked. She looked at herself in the mirror attached to the wardrobe door. Her body was covered in beads of sweat, her blonde hair was all damp with sweat and was sticking to her back. Her face, breasts, stomach and most of her skin was covered in drying spunk that her brother had shot out and covered her in for most of the morning, her pussy lips were red and wide open from the numerous poundings of her brothers dick, and when she turned round to look at her ass in the mirror she saw that it too was covered in drying spunk, and she could clearly see that her asshole was gaping open from the stretching it had received from her brothers numerous anal assaults on it using his big hard 11 inch dick. She concluded that she looked just like a sex slave would after serving her masters every whim. She also thought of what her mothers reaction would be if she saw her daughter as she was at that moment – covered in drying spunk and with her cunt and asshole stretched wide open. She bet she wouldn't be very happy at all!
Debby then chose some clean clothes out of the wardrobe and then made her way into the bathroom ready for her shower.
Meanwhile Nathan had struggled to put on a clean pair of boxers over his hard dick. At first the head and the top few inches of his dick stuck out above the hem of his boxers but eventually his dick started to go a bit softer and he managed to tuck himself in. He pulled on a clean pair of socks, some sweatpants he had worn the day before (mainly on the hope of disguising his still half hard dick) and a clean tight fitting t-shirt that showed of his muscles and an old pair of trainers.
He used his dirty pair of boxers he had had on that morning, to mop up any blobs of his spunk he could find on the floor and then he left his dirty socks, boxers and t-shirt he had worn the previous day on the floor by his wardrobe door. He finally threw the bedclothes over the bed not bothering to try to make the bed properly.
He then made his way from his room and downstairs into the kitchen, where his mom was preparing lunch. He sat down on a kitchen chair by the table.
"Hi Son" said his mom; " Happy Birthday". She looked him up and down as mothers do and thought to herself how strong and handsome he had become. He would be a real catch for any girl she said to herself. "What's it like being all grown up then..." as soon as she said that her mind subconsciously went back to that morning and she blushed a little at the memory of what she had seen, when she had gone into his bedroom to see if he was awake, so she could wish him a happy birthday before she went to work.
As she opened his bedroom door, the light from the landing highlighted the room enough for her to see that he was fast asleep in his bed. He was lying on his back with his body angled slightly towards the door. He had his left hand above his head resting on the pillow and his other was dangling down over the side of the bed. The bed sheets were in a pile at the bottom of the bed as it had been too warm to have them over him. That meant that his body could be seen fully from where she was standing. Without thinking her eyes automatically began to look up and down his body. She slowly took in his young lithe muscular body. She noticed how tight and muscular his chest was and how hard the muscles in his abdomen were.
She felt herself let out a small sigh as her eyes took in her sons youthful toned body. As her eyes travelled down his body taking in every detail she suddenly let out an involuntary gasp as her eyes settled onto his crotch area. He was wearing a pair of boxer shorts but they did nothing to hide the huge bulge that was sticking up inside them and tenting out the material. It looked as though the material was going to give way and tear at any moment such was the pressure of his hard dick against the thin material. She looked up and down the bulge a few times not really believing what she was seeing. Could her son really have a dick that size? She couldn't seem to tear her eyes away from her son's crotch, it was as though she was caught in some spell she couldn't free herself from. Looking at her son's hard massive dick jutting up in his boxers made her think of things she shouldn't have done. Thoughts and questions filled her mind along the lines of; I wonder what it looks like in the flesh? How big is it? How much spunk does it shoot? What would it feel like to have that monster dick inside you? Would it hurt? Would it all fit in a girl's cunt? What would it feel like to have that monster dick inside my cunt? Would all of it go into my cunt?
That last thought jolted her back to reality. Here she was, in her son's room, standing there, staring at his nearly naked 18 year old body with his big dick sticking up in his boxers, and she had just thought of what it would be like to have it in her cunt! The idea repulsed her but that didn't stop her realising that she had become a little turned on looking at her sons naked body and thinking about his huge dick, and about having his huge dick inside her cunt. She could feel that she had become a little wet in her knickers. With guilt racing through her brain of what she had just been doing and the dirty things she had been thinking about, she decided the best course of action would be to leave her sons room as quickly as possible and put those images of his near naked body and her disturbing thoughts about his huge dick and what it could do, to the back of her mind. She pulled the door to his bedroom gently shut and continued to get ready for work. She had tried hard all day to forget what she had seen and thought about in her sons room that morning but seeing him there in front of her had just brought it all back to her.
She regained her composure enough to carry on with what she had started to say before drifting off with thoughts about this morning; "You are now a fully fledged adult. I bet you can't wait to do all the things you can do legally now right?". She hoped he didn't notice her blushing too much.
"Hadn't really thought about it much yet today mom" Nathan replied; "Been too busy doing other things". Nathan hoped his mother didn't see him blush a little as he remembered what he and his sister had been doing all morning while she was out at work.
"I know. You've been studying hard all morning for some exam according to your sister. Fancy studying on your birthday, you should be out enjoying yourself, not stuck in your room on your own, hard at work on some exam".
"It's Ok mom. I enjoyed it. I really learnt a lot this morning".
