William slowly opened his eyes as the morning sun crept in the window. He turned his head and smiled. Lying next to him, on her side with her back to him was Becs. His sexy, amazing, oh so fuckable younger sister. He could smell the sex on her. Another night of incredible fucking in the rearview mirror. He slowly lifted the blanket so as not to disturb her and took in the beautiful sight next to him. Her small 5' 3" frame, hot legs, that incredible tight little ass, the smooth skin of her back and her shoulder length brown hair a mess around her head. He felt the familiar twitch in his cock as he drank in the sight of his sister. He lay still and listened to the soft breathing of her slumber as his cock grew hard. Slowly he turned onto his side and ever so gently draped his arm over her, his fingers finding the stiff nipples of her perfect 34A breasts. She stirred with a moan. Pushing her cute, little butt back into his stiff cock she moaned a bit louder.
"Good morning Becs. Sleep well my sexy little slut?" He kissed her neck as he played with her firm tits.
"Of course I did, after the all night fuck session you gave me I was exhausted." She reached her hand behind her and gripped his rock hard cock. "Oh? Feels like somebody is ready for more." She laughed as her fingers traced the length of his veiny shaft.
Almost simultaneously they each reached for the drawer of their night stands and pulled out a breath spray. One thing Becs could not stand was halitosis. They always laughed when they read Lit stories together and people would wake up and fuck. Becs always said, "I don't care how nice your cock is, nothing will dry this cunt up like a shitty case of morning breath." Having taken care of their nasty breath, they turned to each other dove into a long, hot, passionate kiss. William pulled her over onto his body and held her tight to him. His hands slid down and cupped her gorgeous ass. Becs broke the kiss and gently licked and kissed her way down his body not stopping until her face was even with her brother's cock. She took in the sight of it. She loved his cock, a perfect 7", nice thickness and the sexy, swollen mushroom top. She loved that he was circumcised, it made it look perfect. Her small hand cupped his full balls as she dragggggeeeedddd her tongue up and down the length of his hardness.
"MMMMM, god I can taste us on your cock. So fucking good."
William moaned softly as his sister went to work, doing what she did best, pleasuring him. She was his own personal little fuck toy. A nasty fucking slut for her brother and she was proud of it. She loved letting him use her, treat her rough when he wanted. She loved being his submissive little cock whore. She was willing to anything sexual he asked and she was even more willing when he didn't ask, and just took what he wanted. He watched as she started sucking him, bobbing up and down, his spongy cockhead bumping into her throat as she sucked him deep. She took him all the way in and pressed her cute little nose into his pubic hair. That was one of her proudest moments, the first time she was able to deep throat him. She knew he wanted it so she worked on it relentlessly until she did it.
As she gave William a perfect morning blowjob he spoke, "I have a surprise for you my naughty little sister." She didn't stop sucking but gave him a questioning look with her eyes. "What's the one thing you've always wanted to try?"
This time she did stop. She lifted off his cock. "Shut-up!!! Don't fuck with me."
"Come on Becs, tell me. What's the one fantasy you won't let rest?" He was almost laughing.
"I want......fuck! I want two cocks in my cunt at the same time. Fuck, you better not be teasing me you fucker."
"I met a guy, at the gym. We got to talking about our girlfriends and it turns out she is a bit of a cock slut just like you and has the same fantasy. If you're up for it, he said he would...."
"Fuck yes!" She interrupted. "Fucking when? Call him, I'm so fucking wet just thinking about it."
"Jesus, settle down you nasty little slut," he said laughing. "Here's the deal, we agreed to work together to make both of your fantasies come true. We can do it one of two ways, I go to their house and do it with them and he comes here, or we get together as couples and just let the fun begin."
Becs stopped, her mind racing as she thought about the options. "We've never did anything with other people. What if they freak out when they find out what our relationship is? What if she's super-hot and you fall in love with her and leave me so you can fuck her skank ass all the time?" William smiled as she talked. His sister was actually very introverted in public but when they were alone, she could be a real chatterbox. "What if his cock is so fucking amazing that I become his little slut and you never get to fuck my hot cunt again?" Now she was starting to laugh.
"Ok, look my sexy little sister, first, there isn't a bitch in this world could lead me away from my favorite little fuck toy. Second, I saw his cock, in the locker room, I'm not worried," laughing, "and third, my sweet cock sucking sister........ready? They are brother and sister as well."
