Loving Mother and Innocent Son Pt. 03

"You feel so good, sis. And you're so wet. I never want this to stop." He whispered in her ear, feeling her hard nipples against his chest and her hands stroking his back tenderly.

Smiling to herself, Nat ran her fingertips up and down her brother's spine as she just enjoyed having him so deep inside of her, kissing his shoulder tenderly. "I'm glad you like it, because you can have it anytime you like. Don't ever feel bad or hesitate if you're horny or you just want me. Just kiss me, or touch me, and take me." Her voice was low and soft, and she kissed his neck several times before whispering to him. "You can take me any way you want, anytime you want. And I know mom feels the same. You could even have both of us at the same time. Maybe tonight."

The mental images that popped into his head were enough to cause Simon to swell inside of her and moan softly, and he began fucking his sister slowly but as deep as possible with long steady strokes that had her trembling beneath him in no time. As he made love to her, she took his head in her hands and brought his face to hers and kissed him tenderly, then slowly deeper as he got used to it. Minutes passed as the siblings made love and kissed, Simon becoming better and more comfortable at both as it was all happening so slowly and in such a relaxed way. Soon their tongues were dancing against each other and the kiss became more passionate and hungry until Nat broke the kiss and looked at him for a moment as he stopped moving.

Slowly, she rolled him on his back without sliding him out of her until she was sitting on his cock on top of him. She leaned down to kiss him softly, then she smiled and pulled herself up the long length of his cock, grunting softly as it rubbed inside of her so intensely every damn time. Then she turned to face away from him, looking over her shoulder as she took his cock in her hand to guide him between her legs. "Mom told me what you did, baby bro. And I want you to do it to me, but longer." As she said that, she pressed the head of his big cock against her ass, Simon looking down at what she was doing. "I want you to see your cock slide in and out of my ass Simon. I want to be dirty with you." With these last words, the head forced the tight ring of muscles open and slid inside with some effort, getting a loud moan from his sister.

Simon was staring at her ass now, watching himself penetrate his sister's butt like that and it was tighter than his mother and harder to get in, but she did all the work as she slowly pushed herself down until a couple of inches were inside of her. Then taking her time, she carefully moved up and down, every time taking a bit more of him up her ass. It felt so damn good, he couldn't help but grasp her asscheeks and keep staring as after a few minutes, she pushed herself down one last time to sit on him fully, his entire length buried inside of her backside. Nat couldn't believe how big he felt there, and while it was slightly painful, it felt amazing. "How does it feel bro? You like your big sister's tight ass?"

The dirty talking was new for Simon of course but he found it to be a huge turn on. As his sister looked over her shoulder while slowly lifting herself up his hard cock, making them both moan at the feeling and with her ass squeezing him so tight, Simon nodded and looked at her as she pulled herself up almost all the way and then slid back down, taking him all the way up her ass again. All he could do is moan and watch her beginning to move her hips up and down and fucking herself on his huge cock that felt like it was in her belly.

Eventually, Simon couldn't help but move his hips up and before long he was thrusting up into her, both siblings making obscene sounds of pleasure as her sexy ass bounced in his lap. Looking back at him again, Nat grinned a bit. "Maybe tonight you can fuck mom in the ass in front of me bro. I'd love to see that. You know she licked my pussy this morning before you came in? God it felt good. I wish you could have been in my ass while she was eating me, would have been sooooo hot." In a way, she still couldn't believe she was saying these things and doing these things. Life had changed a lot in the last 24 hours and it was a bit like an erotic version of their lives, except it was all real.

That was too much dirty talking and sensations at the same time for the poor, formerly innocent boy. Hearing his sister say these things and learning what their mom had done was too much, and his fingers clenched Nat's asscheeks tightly as he shook and grunted, and she could feel him cum so hard deep inside of her ass so she just stopped moving and sat on him, keeping him deep and smiling back at him as she watched him ride the orgasm in reaction to her words. She found that she loved feeling him cum inside of her, but next time she would have to swallow him.

Simon opened his eyes after his most intense orgasm yet, catching his breath and shivering when she pulled herself off of him and his cock slid all the way out of her ass. He saw his sister quickly reach for the bedside table and grab a few tissues from the box, putting a few between her legs and then using some more to lightly wipe his cock even though it wasn't dirty, then she tossed them all into the small basket next to the bed and crawled back in his arms, sighing deeply. "Well that was fun. I'm ready for a quick nap now, then maybe we can have a shower together? But no more sex. Need you ready for tonight baby bro." And she grinned at him before laying her head on his shoulder and closing his eyes, snuggling in close.

Her poor brother couldn't relax so easily or so quickly. His mind was so full with everything that had been happening, and all he could do was think about it for a long time. Feeling his naked sister and her large breasts against his side was enough to convince him it was all real, and he looked at her the whole time before finally falling asleep.

Maybe it was all a dream and he would wake up from it.
