This story and all the characters in it are completely fictional. If the idea of sexual intimacy between a brother and sister bothers you, I would ask that you read no further. That having been said, this was extremely fun to write. For those of you who enjoyed the first story, I'd like to say thanks for the feedback and this one's for you. I hope you enjoy it even more than the first.
*********************************
As they lay there on the shower floor lovingly kissing one another, Aaron's hands started to explore Catherine's body more completely. To Aaron there had never been anything to compare with the feel of a woman's body, and his sister's was no exception. He wanted to feel every part of her, and he did. He started by tracing circles with his fingertips around her stomach and through the seam between her beautiful luscious breasts. Then his hands flattened and traced over the top of her breasts and down to the sides of her stomach. He shifted his position to lie on top of her. His penis, beginning to harden once more, rested on her stomach, and his hands traced their way over the sides of her buttocks and down her wonderful thighs.
All the while his lips had moved down to the left side of her neck. They kissed and sucked in the flesh they found there, and then traced their way to the other side of her neck and up her cheek to her ear. He kissed it and blew in it, then licked the inside of it with his tongue. She reacted to all this with a series of low moans, which he exalted in drawing out of her. If there was no feel greater than that of a woman's skin, there was certainly no sound in existence greater than that of a woman's moans.
Dragging his lips over her cheek once more, he kissed and sucked in the bottom of her chin, then worked his way up to tease her lower lip with a kiss. His hands worked their way back up to her wonderfully soft and smooth breasts. He cupped them and massaged them softly, but steered clear of playing with her nipples for the moment. He wanted her to want it. She would earn that nipple play as well as that next passionate kiss with soft passionate moans of yearning.
Sure enough Aaron's treatment did have the desired effect. The moans were barely above whispers but every now and then her feminine pitch would peak through. Every "Oh!" was intoxicating to Aaron, so her rewarded her by circling her nipples with the tips of two fingers and then cupping he breasts once more, working his fingers around to encircle and then enclose the beautiful hard nubs. The moans he drew this time were louder, and he rewarded them with a passionate kiss on the lips. She met the kiss with renewed vigor, her hands sliding over the sides of his face and combing through his hair to pull his head closer to her. As she did, Aaron's hands pushed into her breasts pushing her erect nipples inward.
Catherine then rolled Aaron over to get on top of him. He'd made her feel so good that she felt she had to reward him. She kissed him passionately then broke it, to work her lips down the sides of his neck, over his nipples and stomach and down to his, once more, fully erect, rock hard cock. She took hold of it with her right hand and with little to no warning, started kissing it. She started kissing the head, and then sucked all along its sides, until finally she brought her other hand to his balls and enveloped his cock in her mouth. She pressed her tongue against the bottom of it, and started moving up and down along its length. Tilting her head slightly sideways she allowed the head of his cock to pound into her cheek, while she circled the shaft with her tongue. She then titled her head the other way, circling his cock with her tongue the entire time, and allowed his cock to pound into her other cheek.
Aaron's dick felt so wet, so warm, so tingly, and so god dam tight he didn't know if he could stand it, but he enjoyed the challenge immensely. Soon Catherine began sucking him straighter and faster. Her mouth drew tighter around his shaft and she would twist her head so that it circled out as she pulled out and circle in as she pushed in. All the wile her tongue had flattened itself to the bottom of his cock. She loved the taste of his manhood, and was now starting to enjoy the pleasure of his soft moans.
To Aaron the feeling of his sister's mouth was heaven. As she went faster he felt more and more intensely the roughness of her tongue and the softness of her lips pressed tightly around him. He was going to cum soon and she was going to swallow it.
"Oh fuck, yeah! More sis, more! Harder! Make me Cum! Oh Fuck! Oh Fuck! Oh... OHHHOOOFUH!"
Sperm jetted out of cock and into her mouth. It spewed out like water from a fountain and she drew out every last drop, and swallowed it.
When Aaron finally recovered his breath the first words out of his mouth were "Holy fuck sis, where in the hell did you learn how to give a blowjob so well?"
"I could ask you where in the hell you learned to eat a woman (refer to the original story for details on that) and tease her body so well. You are the best most attentive man I've ever had at that. God you deserved a good blow job for that."
"Thank you. I take pride in giving women pleasure."
"I could tell."
