Sue looked at herself in the bathroom mirror the next morning and couldn’t stop smiling. Nothing looked different, she still had the same oval face, brown shoulder length hair, and the largest set of tits in her class, but she knew something was different and she just couldn’t stop smiling as she felt her father’s cum drip out of her cunt lips to slide down inner thigh.
“Morning sis,” Dave said as he stepped through the open bathroom door to slide behind her. Sue watched her brother in the mirror as he got behind her and slipped his hands around to grope her tits. “So, how did you like losing your cherry?”
“I loved it,” Sue sighed with a blissful grin as Dave played with her tits, pinching her nipples when they popped erect under his fingers. “And I love what you’re doing too.”
“How would you like to do something more?” Dave asked as he ran his left hand down his sister’s flat belly to her drooling pussy.
“You must be reading my mind,” Sue moaned as her brother played with her clit. “Or at least my cunt. I’d love another morning fuck.”
“So would I,” Dave said, leaning forward to put his lips next to her ear, “I already fucked Cindy and Janet, but I’m ready for another round.”
“Good,” Sue said, pushing her ass back so Dave’s prick poked her between her cheeks. “But if we fuck now will you be able to get it up for the orgy this afternoon?”
“You’re joking, right?” Dave asked as he continued playing with his sister’s tits and cunt. “Dad is the only person I know with more fucking stamina than me, and I can give him a run for his money.”
“Then it sounds like we’re going to have ourselves a fuck,” Sue said as she reached back to grab Dave’s hard cock. “But now you have to make a choice.”
“What do you mean?” Dave asked.
“Last night I decided that I wanted my first baby to be dads,” Sue explained. “That means that until I miss my first period and the stick tests positive daddy will be the only one cumming in my cunt. So I’ll give you a choice, you can wear a condom to fuck my pussy, or you can fuck my ass, or my mouth.”
“I know how good your blowjobs are,” Dave admitted, “but I’ve had them before and right now I want something new. And since I hate wearing a raincoat I guess I’ll choose your ass. What do you want to do for lubrication? I think there’s some KY jelly in the medicine cabinet.”
“Yeah,” Susan said thoughtfully, “but I prefer something natural this time. How clean is your cock? You said you already fucked Cindy and Janet, did they suck you clean afterward or do you have some cum on your cock?”
“Oh, they sucked me clean,” Dave said with a happy grin.
“In that case stick your prick in my fuck hole a few time to lube it up and then go for my ass. Just make sure that you don’t stay in my cunt any longer than you have to.”
“Ok,” Dave said, giving his sister a happy grin as he brought the head of his cock up to her pussy lips. He held Sue’s hips steady and shoved his cock into her fuck hole with one quick thrust.
Sue groaned in pleasure as Dave’s cock tickled her cervix, for a second she was tempted to give up her decision to only let her father cum in her. She took a deep breath and held to her original decision in spite of how good her brother’s cock made her feel as it fucked in and out of her.
“Hey Sue,” Dave said with a grunt as he made one more thrust before pulling out of his sister’s cunt and shifting to her puckered asshole.
“What is it Dave?” Sue asked, letting out another groan of pleasure as her older brother slid most of his cock into her ass.
“I was just wondering, since you’re giving dad exclusive rights to your cunt until you have his baby in your belly,” Dave said as he shoved the last inch and a half of his prick into her ass with such force that his balls bounced off her cunt.
“Yes?” Susan said with a hiss of pleasure.
“How about giving me exclusive rights for your second baby, sis?” Dave asked in one quick breath. He could see the look on his sister’s face in the mirror as she considered his question and he suspected the answer even before spoke.
“I’m sorry, Dave,” Sue sighed as her brother fucked her ass. “I’m going to have enough trouble giving dad an exclusive for this baby. Do you have any idea how hard it was to let you pull your cock out of my cunt? I was tempted to forget my decision and let you cum in my cunt, I’m glad you pulled out before I begged you to shoot off inside my fuck tunnel.”
“No problem sis,” Dave said as he bent forward to kiss the back of her neck as he played with her tits and clit. “As much as I’d like a chance to father your first baby, I can understand how much you want to have dad’s baby first. But once dad takes care of business I think you’re going to be the slutiest girl in town, Cindy and Janet will have nothing compared to you.”
“I hope you’re right,” Sue gasped as she felt an orgasm building up in her belly as Dave’s shaft slid in and out of the depths of her bowels. “I just hope I can hold out long enough to have dad’s baby in my womb before I start fucking every cock in sight until I have so much cum stuffed in my fuck hole nothing else will fit.”
“I look forward to the day that happens,” Dave chuckled. “Because I think I’ll have more cum in your fuck hole than anyone else you hot little slut.”
“You make me so fuckin’ hot, big brother,” Susan said as Dave slammed his cock into her ass like a piston. She could feel her cunt vibrating on the verge of her orgasm as Dave played with her nipples and clit. In the mirror she could see both their faces, hers wide eyed with pleasure and his contorted in concentration.
Sue’s orgasm hit her like a ton of bricks and her ass hole clamped Dave’s cock so hard that he couldn’t move it for a few seconds. As his sister’s cunt and ass spasmed a jolt of sexual energy hit Sue so hard that Dave had to support her as her legs gave out on her.
“Hang on, sis,” Dave said as Sue caught her breath and tried to support herself on wobbly legs. “I plan to give you at least one more cum just as good as this one before I cum myself.”
“Oh goody,” Sue gasped as Dave started fucking her ass again, “I can’t wait to have another orgasm like that one.”
“And I can’t wait to spray you full of baby juice,” Dave said thrusting two fingers in his sister’s tight cunt as he slammed his prick into the girl’s ass. “Even if you won’t have my baby first it’s only a matter of time before I knock you up.”
“I hope you’re right,” Sue groaned as her fuck tunnel sucked her brother’s invading fingers as they pushed her toward another orgasm. “I’m going to cum again, Dave.”
“Good for you you little slut,” Dave grunted, he could feel his balls tightening at the base of his cock and he knew he was about to cum too. “Let’s cum together Sue.”
“Yeah,” Sue screamed as Dave slammed his cock deep into her bowels and held it there as he sprayed his sister full of cum. Susan could feel her brother’s baby juice fill her asshole as another orgasm shot through her body again and she collapsed on the counter, trapping Dave’s hand under her quivering tits.
“Oh God,” Dave sighed, giving his sister an open mouthed kiss and wrestling with her tongue. “You are one hot little slut.”
“Thanks Dave,” Sue said as her brother pulled away from her lips and her ass. “How about showering together?”
“Sounds great,” Dave said with a lopsided grin, “but I don’t think I can get it up for another fuck right now.”
“I don’t care,” Sue said, “I just want to shower with you and that’s all.”
