Debby arrived home a little after 6.15pm unaware of what her mother was planning for her. Debby had returned as quick as she could from her friends because she couldn't stand being away from the house any longer. She was afraid that Nathan would be back before her and she would miss out on spending more "quality time" with her little brother. Just the thought of what they were going to do to each other later that evening had already started to get her a little horny and wet between the legs. She was trying hard not to show how turned on she was, but it was proving difficult. She really wanted her brothers 11" inch cock back inside her body as quickly as possible.
As she entered the house, she went straight into the kitchen and she noticed that her mom was sitting there at the table flicking through a magazine. Debby was also unaware that at that moment, her mother was trying to act calm and collected, and trying hard to stop herself blushing too much, when she remembered what she had done earlier that afternoon in her sons bedroom and about the question she was about to ask her daughter. Unknown to Debby, her mother was also turned on and was also a little wet between her legs thinking about her son's, Debby's brother's, 11" inch cock and what she would like to do with it. Both daughter and mother were thinking the same thing at the same time. How to get Nathan's 11" cock into their own bodies as quick as possible without the other one finding out. Since this morning both women had become obsessed with Nathan's big cock and would, by now, do just about anything to be able to see it again in all its glory.
Debby's mothers mind returned to the present and she was now prepared to ask her daughter the question she knew would embarrass her daughter no end. She was unaware, however, that the question she was soon going to be asking her daughter as a joke, to make her daughter embarrassed, would soon, and totally by accident, uncover Debby's and Nathan's incestuous secret.
"Did you have a good time at your friends?" enquired her mom, looking up from the magazine.
"Yes thanks, it was great. Just catching up on gossip and things you know" replied Debby.
"Good. It's always nice to have friends to talk to isn't it?"
"Yes" agreed Debby, not knowing what else to say in reply.
"Yes it's really good to have close friends. You can ask and tell them things you wouldn't want to ask, or tell your parents right?"
"I suppose so..." replied Debby, again not elaborating the point. Debby thought her mom was trying to ask her something but didn't want to directly, so she was being a little decisive; "Why?"
"Nothing... It's just that you can tell your friends, you know, embarrassing stuff or really private stuff. Things, for example, you wouldn't want your parents to find out about right?"
"I suppose so" replied Debby, hesitantly, a little unsure to what her mom had just said or what she was implying, even though at the back of her mind Debby thought her mom was definitely implying something; "Why?"
"Oh, nothing much really...I just wondered if there was anything you wanted to tell me that's all...stuff that has happened recently that you think I should know about"
"No" replied Debby a little unsure about what her mom was implying; "I haven't got anything to tell you. Why?"
"Are you sure Debby? There is nothing you want to tell me about?"
"Like what?" asked Debby, her heart beginning to beat a little faster.
"Oh I don't know...possibly something to do with your brother?"
"What about my brother?" asked Debby her heart beginning to beat a little faster still.
"Oh nothing...it's just a bedroom habit of his... I found out about this afternoon whilst cleaning his room...". She couldn't finish what she was going to say due to Debby butting in; "What...what about my brothers bedroom habits?...What did you find?" Debby's voice began to trail off at that point. She felt her stomach begin to tighten up and she felt herself beginning to blush a little. Had her mother found out about her and Nathan? She couldn't bear to think that she had. The consequences would be too terrible to contemplate.
Debby's mom noticed that Debby had begun to blush a little. Her plan was working. She was making her daughter feel embarrassed. She was now sure that Debby new about what she was talking about, and knew what her brother had been doing to himself, in his bedroom, whilst using her knickers. She was enjoying seeing her daughter squirm a little.
Debby's mother continued; "It's just that while I was cleaning your brothers room this afternoon, I learnt something about him...and his bedroom habit...that shocked me..." She paused for effect and as she said the words she was trying to hide a smile. She was slowly building up the pressure for when she would ask her daughter the question she had been waiting to ask all afternoon. After a short pause her mom continued; "and I just want to find out how long it has been going on...and why you haven't told me about it... How come I only found out about it this afternoon?"
Unfortunately, at that moment, Debby's mind was whirling with what her mom had just said. She didn't know her mom was teasing her. She didn't know that they were talking about two totally unconnected things at that moment. Debby immediately began to think the worst. Did her mom definitely now know about her and Nathan? If so how did she find out? What was she going to do to them? Question after question flooded her mind, with no answers to any of them. She began to breathe faster and she could feel her legs begin to shake a little.
"Well?" said Debby's mom looking directly into her daughters eyes; "Care to offer any sort of explanation?... Why haven't you told me about it before?...Why did I had to find out about it myself this afternoon?"
"I...I don't know what you mean" Debby meekly replied, not wanting to give too much away, just in case her mother was just fishing around for answers, for her to confirm her suspicions.
"Oh yes you do...you can't possibly not know what I am talking about..." She paused again for effect for a moment.
"I don't know what you mean" replied Debby, her face reddening a little more.
"Don't give me that...I'm not stupid...the evidence was all around your brothers room...he must have been doing it for some time...you must know what I mean"
"No...no I don't" replied Debby meekly.
"You must do" insisted her mother; "Evidence of what your brother had been doing was all around his room...the crumpled bed clothes...the spunk stains on his bed sheets...his still sticky cum covered boxer shorts...it can only mean one thing can't it?"
Debby's eyes began to widen at what her mom was saying. She had never used words like that before directly in front of either her or her brother (even though Debby had heard her mother say similar things occasionally while her mom and dad were in bed together and she had called out in heat of the moment loud enough to be heard by accident). Her face went a little redder at hearing her mom talk like that. Her mom took this extra reddening of Debby's face as a sign that Debby definitely knew what she was talking about, and she knew exactly what her brother had been doing whilst using her knickers. Debby was sure by now that her mother knew what had been going on between her two children. Her heart sank and she began to get scared.
Then her mother, keeping her eyes firmly fixed on her daughter's eyes, went in for the kill. This was the moment she had been waiting for. If this didn't get her daughter's face lighting up redder than a traffic stop light then nothing would. She placed her hand slowly into her blouse pocket and ever so slowly removed Debby's black thong knickers from the pocket. She held them up in her fingers so as they dangled down in full view of Debby. She paused just long enough for effect, then said very slowly and deliberately for maximum effect, and in the most pretend stern voice she could find; "Care to tell me Debby...how...while cleaning up this afternoon...I came to find your knickers...your black thong knickers...your still damp knickers... in your brothers bedroom...and in his bed?"
