Chapter 11

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.
