Natasha, who was twenty, walked into her sister’s bedroom, Lauren, who was twenty-two. Lauren was on her naughty spot, her nose pressed against the wall, with her hands on her head. 

Natasha said to Lauren, “Mum has said you can come away from the wall and is expecting you downstairs.” 

Lauren turned and said to Natasha, “I heard Mum spank you.” 

Natasha had already been to the bathroom to see her bottom in the mirror, but before answering Lauren, she turned and showed Lauren her bottom, and Lauren gasped at how red and even bruised Natasha’s bottom cheeks were.  

Natasha smiled as she replied, “Wow, yes, she did spank me, and how. It was so humiliating, standing there as she took my knickers down, then raised my nightie up above my tummy, even more so when she put me across her lap, and still more so when I felt her hand rubbing my bottom in circles. However, I just felt so submissive, and, as you and I have discussed, I just wanted it to happen. Well, it happened, and my bottom is really stinging. The spanking was hard enough when Mum used her hand, but, I can tell you, there’s a real reason why, on those spanking sites we look at, the hairbrush is described as the horrid hairbrush, because that really hurt. Nevertheless, I am pleased you told me to take the hairbrush with me so Mum could use it on us.” 

Lauren saw Natasha smile, and so asked, “Did it also get you aroused, Natasha? Are you wet?” 

Natasha was blushing, but still smiling, as she replied, “Yes, Lauren, I am aroused, and I am wet. Now, though, it’s time to see whether the same will happen to you.” 

Lauren bit her lip as she was worried about what was going to happen, bearing in mind that she was already twenty-two and had never been spanked before. On the other hand, when she and Natasha came home much later than they said they would last night, in fact, pretty much early morning, their mum said she had had enough and wanted to introduce spanking as their punishment. 

It wasn’t a surprise, as both Natasha and Lauren were quite used to going online on their computers and watching spanking porn. It came to light when their mum came into the living room and Lauren hadn’t heard her, but was watching spanking porn at the time, and their mum saw that. It was just a short step from there for their mum to tell Lauren that she was going to be spanked the next time she disobeyed her, and every time after that.  

Although Natasha hadn’t been caught watching porn, Natasha had said to her mum, that if Lauren was going to be spanked, then it was only right that she, the younger sister, was also spanked. 

Although their mum immediately agreed that they would both be spanked from now on, Lauren and Natasha weren’t sure that their mum would actually carry out the threat. They had come close to spanking each other, but even though they looked at porn together, they hadn’t taken that step. So, that was why, just two days after Lauren was caught looking at the porn, both girls got home much later than they had said they would, on purpose. 

Their mum, Sandra, was forty-five and divorced. In the morning, she told both girls they were in for a spanking, but she had to go out for the day, and so they would be spanked before going to bed. That gave the girls time to discuss what might happen, and how they were likely to react to being spanked. They wanted to encourage their mum to spank them, so they discussed how they must obey every instruction, not resist, and must thank their mum for spanking them. They both agreed, although they became increasingly tense as the time got closer to when their mum was going to come home, and so closer to when they would be spanked for the first time. 

So, now, at bedtime, it was the first time that they were both going to be spanked, and by their mum, which they agreed was much better than them spanking each other. 

Sandra decided that Natasha would be spanked first, and Lauren was sent to the naughty spot in her bedroom, where she had to press her nose against the wall with her hands on her head. That punishment had been in place for a while, and neither girl complained as they saw it as them being submissive to their mum.  

As Natasha had now been spanked, it was Lauren’s turn. Knowing it was inevitable, and also looking forward to the experience, Lauren smiled at her younger sister, then walked out of her bedroom and went downstairs to find her mum in the dining room. She was still tense, but felt aroused as well, and was pretty sure that her knickers were already damp. 

When Sandra saw Lauren come into the dining room, she immediately instructed, “Right, young lady, come and stand by my side.” 

Lauren was, like Natasha, wearing her nightie with knickers, and was ready for bed. Well, actually, it was only 9 o’clock, but part of the punishment was early bedtime for the two of them.  

Lauren went and stood by her mum, and forced herself not to do anything as her mum eased her fingers inside the elastic of her knickers, and yanked them down to her ankles. After that, her mum lifted her nightie up almost to her breasts, and instructed, “Get your naughty bottom across my lap.” 

Lauren blushed as her pussy hair mound was now on show for her mum. Lauren reckoned that her mum hadn’t seen her pussy hair mound for a while, but then, other women had at the gym. They didn’t touch her, though, not like her mum was doing right then, rubbing her bare bottom. On the other hand, her mum wasn’t being sexual, unless you include kinky sex, and Lauren knew that she was the one who was into kinky sex as she looked at spanking porn.  

Lauren certainly understood the feeling of humiliation that Natasha had explained to her. However, she knew that humiliation was very much part of being spanked, particularly as both she and Natasha were very much up for it.  

Once the spanking started, Lauren wasn’t quite so sure. After all, it didn’t take very long for her bottom to start to sting, and even when she felt her eyes filling with tears, the spanking just continued. 

Lauren wasn’t expecting to be so close to tears so soon, particularly as she had heard Natasha being spanked, and, as she had her nose pressed against the wall, she had kept a rough time of how long the spanking took. Well, if her spanking was going to be as long as Natasha's, then there was still a long way to go, and her bottom was already stinging.  

Sandra was really pleased that she had caught Lauren watching the spanking porn, because she had often thought about spanking her daughters. She never did, and, now that they were twenty and twenty-two respectively, she thought that possibility had long gone. So, when she caught Lauren watching porn, she thought that was the best present ever. 

Sandra had also made a point at looking at both girls' knickers and saw they were stained with their sex juice. That spoke bundles, Sandra happily told herself. 

Now that Sandra was spanking Lauren, she wanted to really thrash her. She wasn’t being vindictive or anything like that, but she reckoned that the harder she spanked Lauren, the more likely it would be that she would want to be spanked again. It did sound as though it should be the reverse, but if Lauren got sexually aroused by being spanked, which, clearly, she did, given the spanking porn that she was watching, then anything other than a hard spanking could be less sexually arousing, and could put her off. 

What Sandra found, possibly to her surprise but maybe not, was that she felt her knickers getting wet as she gave both daughters a spanking. Her original thought about spanking both girls was because they didn’t always do as they were told, and she thought that giving them a spanking would give her greater control over them. Now, though, as well as seeing the benefit of that increased control, she was thinking about what could happen if the girls were as sexually aroused as she was right then. 

So, Sandra continued to spank Lauren’s bare bottom, loving how each bottom cheek flattened under her hand, how Lauren was squirming around on her lap and gasping with each spank, but, quite noticeably, was not trying to force herself up. Nor did Lauren try to cover her bottom cheeks with her hand, so it was all going in the right direction, Sandra told herself. 

Lauren struggled more than she had expected. After all, some of the women on the spanking porn sites had thick welts across their bottoms but didn’t cry, or, if they did, were smiling soon afterwards. The reality, Lauren realised, was different, as the pain was intense and nothing to smile about. 

Even as she started to cry, Lauren reminded herself that Natasha said how much it hurt her, but she was aroused as well. Lauren hoped that meant her arousal would return once the spanking was over. She hoped so, anyway. 

Once her mum started to use the hairbrush on her bottom, Lauren really was struggling. How could Natasha have found this amount of pain sexually arousing, Lauren asked herself? Could anyone? However, she forced herself to stay across her mum’s lap, just letting out yelps of pain as each spank landed, and just told herself that if Natasha could take it, so must she.  

Upstairs, Natasha had gone back into her bedroom, standing with her nose pressed against the wall and with her hands on her head. She didn’t mind that that was how their mum punished both of them, supposedly giving them thinking time to think about what they had done wrong. Actually, all Natasha ever did was play the pictures and videos she had seen on the spanking porn sites over and over in her mind, and the time soon passed. 

This time, instead of that, Natasha was listening to the spanking that was taking place downstairs, and as much as her own bottom was continuing to sting, she knew that she was getting wetter and wetter as she heard each spank land, and felt her vulva throb so deliciously. 

Natasha could also tell when the spanking changed from their mum’s hand to the hairbrush being thrashed down on Lauren’s bottom. Each spank was much louder, as was each gasp coming from Lauren. Natasha supposed that the same must have happened when she was spanked with the hairbrush. Nevertheless, Natasha was really pleased that Lauren had had the foresight to tell her to bring the hairbrush with her, bearing in mind that she was going to be the first one to be spanked. It certainly made the spanking far more meaningful. 

Sandra kept on spanking Lauren until her bottom was not just bright red, but was starting to be bruised. That was how far she went when spanking Natasha, and thought it right that she also did it to Lauren. After all, when Natasha got up from her lap, she had said, between sobs, "Sorry for being naughty, Mum, and I’m guessing that you’ll now be spanking us in future. I fully understand, and, I’m guessing, Lauren will as well.” 

Sandra knew that time would tell on that, and maybe she would find out very soon because she reckoned it was time to stop spanking Lauren, at least this time. So, she stopped spanking with her hairbrush, and said, “Okay, Lauren, you can get up now.” 

Lauren was thankful that the spanking was over, given just how much her bottom was stinging. Would she ever recover, she wondered. However, within just a few moments, she started to feel the sensation of her vulva throbbing, and so now really did hope that this wouldn’t be the last time her mum spanked her.  

She was also thankful that she had discussed with Natasha what to say after the spanking, and, when she got up, made pretty much the same comment that Natasha had made, thanking her mum for the spanking, and saying she understood if spanking was going to be used again in future. 

Sandra took that as a real positive, and, just as she had done with Natasha, she looked at Lauren’s pussy hair mound, knowing that it was so unlikely that Lauren could tell that she was doing that given how her eyes must be filled with tears, and saw that, just like Natasha, Lauren’s hair mound was glistening wet. 

That said, and sure that she would use spanking again, maybe for years to come, Sandra was already thinking about a fantasy she had had for a couple of years now. She had never met anyone new after her divorce, but also noticed that neither of her daughters had many girlfriends or boyfriends, although she knew both were into girls. In fact, she remembered the time when she heard erotic gasps coming from Lauren’s bedroom, and when she went into Natasha’s bedroom, she found that empty. What became clear, was that Natasha and Lauren were into each other, and it seemed in rather a big way.  

So, Sandra was now wondering whether she could barge in on her two daughters and make it a threesome. 

To test that, she waited for Lauren to go back to her bedroom, and then followed her up a few minutes later. She knocked on the bedroom door, because, after all, following the spanking, her older daughter was once again a good girl. When Lauren called out to enter, she saw the surprise on her daughter’s face because she thought it was going to be Natasha. 

Sandra then said, “You and Natasha will be sleeping in my bed tonight. Don’t bother with your night clothes, just go and get into bed.” 

Lauren was surprised at that, as she didn’t realise that her mum knew that she and Natasha made out together so often. She didn’t question it, and instead, pulled her nightie up over her head, put it on her bed, and then walked out of her bedroom, into her mum’s bedroom, and got into bed.  

Lauren was even happier when, just a few moments later, Natasha came into the bedroom, already naked, and got into bed with her. 

What surprised both Natasha and Lauren was that a few moments after that, their mum came into the bedroom and immediately got undressed. She didn’t say anything as she then turned out the light, and got into bed, placing herself between the two girls. 

Even with the light out, Sandra could see the look of surprise on both of the girls' faces. She was ready for that, and said, “Don’t worry, girls. I know the two of you make out, so I will now make it a threesome.” 

The girls were up for that, as, in fact, when Lauren and Natasha had made out before now, they had even joked about their mum joining them. So, just moments later, Lauren was licking her mum’s very wet pussy lips, whilst her mum was kissing and sucking Natasha’s taut nipples. As Sandra exploded in a huge orgasm, she quickly recovered, and started to kiss Natasha’s inner thighs, working her way up to her daughter’s wet pussy lips, and brought her to a huge orgasm. 

On and on, they gave each other a whole series of huge orgasms, until they were all exhausted, but exhilarated at the same time. 

The following morning, as the three of them lay in bed, Sandra in the middle with her arms around each daughter, and each daughter cuddling into her, Sandra said, “Don’t worry, girls, this doesn’t change anything. Well, I suppose it does because I reckon that we’ll be doing this time and again. What it doesn’t change, is that I will still be using spanking to punish you.” 

As Sandra said that, both her daughters hugged her even tighter, and knew that was exactly what they both wanted. What they loved was that their mum obviously wanted it as well. 

Feeling the hugs, and there being no objections, Sandra knew that family life had just taken a major step forward, and one that all three of them were going to get so much from.
