When the siblings came back in the house, their mother was gone. A note was found on the kitchen counter simply saying she needed to clear her head and that she went for a run.
Simon and Nat exchanged a worried look but then Nat shrugged and after giving it a quick thought, she realized it more than made sense. So they both showered in their respective bathrooms like usual and then waited for Lexi to come home. But she didn't come back until much later and so they had to go to bed. When the time came, they both realized they didn't want to sleep alone and they went to Simon's room. Nat had her hair in a ponytail, bright eyes shining in the soft light of the room and so much of her soft skin exposed thanks to the small shirt and soft cotton shorts she was wearing. Without a bra and in that shirt, her breasts looked even more perfect and her brother remembered how they looked back in the hot tub.
As he pulled back the sheets and sat on the edge of the bed, Nat caught him looking at her in that special way, love and lust mixed in his eyes. Things were different now in more than one way and her mind was still trying to deal with it all but no matter how much she thought about it, all she could think was that she loved her brother and mother more than anyone else and even after making love to her own baby brother, she felt better than before. It went beyond the sex, being with him had made her feel so much closer than before and it felt almost right. And then the other side of the coin was that she was attracted to him in a sexual way now, there was no way around it.
Slowly walking to stand in front of him, she smiled down at him and he did the same. "I like sleeping naked, baby bro. Do you mind sleeping naked with me?" And with that she began pulling her shirt over her head deliberately slowly, flat stomach exposed first then her large breasts coming free for him to see. Then she hooked her fingers into her shorts and pushed them down her shapely legs, kicking them off before standing fully naked in front of her brother. She was stunning really, with rounded hips and narrow waist. Her breasts were heavy but high, and there was no trace of hair on her young pussy.
Watching his reaction and seeing that he was hesitating a bit like before, she smiled and laughed softly as she got to her knees in front of them and pulled his boxers off slowly, and that's when he pulled off his shirt. Nat looked down at his cock, so large even when soft. And she knew how much bigger it got when it was hard. So she looked up at him as she got up and walked to the other side of the bed, getting under the sheets and waiting for him to do the same. "Hug me and fall asleep with me?"
Simon nodded quietly and opened his arms and she came close, laying her head down on his shoulder as they lied on their backs and snuggled their naked bodies together tightly. Before they knew it, they had fallen asleep.
The next morning, Nat was the first to wake up and she watched him sleep for a long time while gathering her thoughts before she got out of bed quietly, put on her clothes and stepped out of the room. When she walked into the kitchen, her mother was sitting at the counter having coffee, clad in her robe. The both of them looked at each other without saying a word at first, since Lexi had no idea what to say. Then Nat made a decision and she walked over to her mom and she put her arms around her to hug her. Surprised, Lexi returned her hug with a relieved sigh. "You don't hate me, baby? I couldn't blame you if you did, I..."
Nat pulled back slightly and put a finger on her mother's lips, shushing her and looking into her eyes with a serious expression on her face. "I know, mom. I have no idea what went through your head or why you did it, but it's done and now we have to accept that things are different. Simon explained what happened. But I have to tell you something too." Taking a deep breath, she looked at her mom. "Simon and I had sex in the hot tub yesterday after you left. It just felt right and I love him. And I'm dealing with it in my own way."
Lexi had a shocked expression on her face for a moment as she wrapped her mind around this revelation. She knew she couldn't be mad, and she knew there was no place for jealousy of course. After a minute of silence, she looked at her daughter in a slightly different way. "Why did you do it? I didn't plan for it. He was so upset after school and then it was just a massage, but then he told me about his friends talking dirty about me while bullying him, and then I kept massaging him and...he was so hard so I asked him if he wanted me to rub him. I didn't think about what I was doing. Next thing I knew, I had him in my mouth and then it ended with what you saw in the bathroom. But...why did YOU do it?"
It took a long moment for Nat to process all this and think of her answer. This was a strange conversation to have with your mother about a very strange situation. But the weird thing was that she didn't regret any of it. It somehow put some things in perspective in her life and if it had been wrong, she would regret it. But she didn't. So she looked into her mother's eyes and shrugged. "I'm not sure. He told me what happened and he was upset and worried I was mad and that our lives would go to shit, I guess. So I hugged him for a long time. And felt something inside, which was made worse when he caressed me in a very normal way." She paused as she was almost reliving the events that led them to this point.
"And then I felt him against me and he was so hard, like you said. And so big. So I touched him and stroked him and he did the same to me. And mom...I don't know how to explain it. I was hugging him but it wasn't enough, wasn't close enough. I wanted to be closer to him. So I took him inside of me and made love to him like if I was his girlfriend. And then we went to bed and fell asleep in other's arms. And I haven't slept this good in as long as I can remember. So there you have it." The whole time she was talking, Lexi was staring at her and listening intently, having very mixed feelings about the whole thing. Of course she understood and this was weird and even wrong, but she understood how her daughter felt. From an outside perspective, this was beyond horrible.
