Blair and Elijah froze. His hands still on her exposed naked breasts and his cock still shoved into her tight pussy, both of them twitching for a release. From his position in the doorway, their father spoke, "Oh please, continue. I've rather been enjoying myself watching my children fuck for the past 20 or so minutes. Blair, your face is beautiful when your brother makes you cum."
Still, Blair and Elijah stayed still even though his cock was twitching to fuck her more and he could feel her pussy pouring juice out all over him. Their father, Paul, stood there with a bemused expression for a moment before he growled, "I said continue now" Elijah began to pump his cock in and out of his sister's tight hole again and twist her nipples as their father stood there and watched.
Paul moved silently into the room, his own cock expanding with each step, until he stood directly in front of his beautiful little girl. He unzipped his pants and pulled out his own massive cock, and shoved it into Blair's mouth telling her to do what he had taught her. Blair began to suck her daddy's cock while her brother fucked her from behind. After only a few minutes and without warning, daddy shoved his cock deep into Blair's throat as he came.
Elijah had Blair cumming the next moment as well as himself, filling her to overflowing with his hot potent cum. Before he could extract himself, their father said, "Here, pull your cock out and put this in. Blair, you are no longer on birth control, not that you ever really were." Daddy handed Elijah a special plug that wouldn't allow his semen to escape Blair's pussy.
Later that morning at breakfast Elijah and Blair were both on edge, dad didn't seem mad or upset at all about catching his children in such a compromising incestuous position, in fact he seemed amused.
Elijah was concerned about what his father had said to Blair before shoving his dick down her throat, "'do it like you've been taught'" how long had their father been molesting her and to what extent? After breakfast they were headed upstairs to their separate rooms when their father stopped them, "You two, den now." he commanded. He had used his I'm not kidding voice which put them both on edge.
After they entered the den, their father indicated for them to sit on the couch before he started to speak again. "First, let me say your mother will not be home for quite awhile. She is taking an extended vacation at a spa and then she's going to her sister's for awhile. Second, let me address Elijah's unasked question. I started training Blair on how to properly suck dick the day she turned 18. So almost a year ago and yes that's all I've trained her in. Third, while we are all here together without the presence of mommy dearest, here's what's going to happen, you two can fuck wherever and whenever you please, birth control is not allowed, and if I so choose I will join in or watch whenever I want. Does everyone understand?" They nodded yes in unison. "Good. Also, Blair you will not wear panties or bra of any kind unless that's the entire outfit, you will also be sure to wear only your shortest skirts and dresses, the tighter or more see through the better. Do you understand?" "Yes father." "Good, that's my good girl. Now, stand up please. Elijah, pull the plug, let's see if you're soon to be a father or if it all runs out, shall we?" Elijah reached between his sister's legs, ran his fingers up and down her slit a few times before grabbing the plug and removing it.
Cum came pouring out of her cunt and down her legs, still hot and thick. "Elijah, take your mouth and clean up your sister's thighs, but don't touch her pussy. Elijah quickly dropped to his knees and went to the task, licking his own cum off of Blair's legs and thighs. Once he was finished, Paul told Blair to lay down on her back on the couch, as soon as she did, her father pushed her knees open wide to see her pretty little pussy and to note that it was very wet and shiny with her juices and her brothers. He leaned down, inhaled her scent deeply, and then plunged his tongue into her pussy, licking up and down her slit slowly, before using his fingers to spread her lips apart and plunge his tongue deep into her cum hole. After licking and sucking it clean he moved up to her sensitive little nub and began to flick his tongue over it before latching down and sucking on it.
Her father was eating her out. Her father was eating out her freshly brother fucked pussy and seemed to be loving it. The look on Elijah's face was one of amusement, shock, and jealousy. Blair reached for his cock to suck on while her dad continued to work her clit with his mouth and was now sliding 2 fingers into her tight pussy. Daddy apparently did know best. As her dad licked her clit and rammed his fingers inside of her, Blair latched her cute little mouth onto Elijah's massive cock and started sucking and working his dick like she'd never get another taste. Elijah was starting to cum, letting the hot spray go down Blair's throat as she continued to suck greedily on his cock. Blair was brought to orgasm at the hands of their father, rewarding him with a face and mouth full of pussy juice. When she came she sucked so hard on Elijah's cock he almost hit the floor from the intensity. Dad stood up, face dripping and said, "This should be a very interesting summer." Then turned and left the room.
Elijah and Blair went to their rooms as he to nap, and she wanted to take a nice hot bath. She must have dozed off in her bath because she awoke with a start and the light from the window indicated it was mid to late afternoon. She stood quickly and rinsed off the remaining bubbles, then went to get dressed. She selected a mini skirt from 2 years ago that was 3 inches too short now, barely covering her ass, and a fitted sheer top. Blair headed to the kitchen for a quick bite to eat and then headed to the family room to watch TV. Elijah was in there staring blankly at some TV show, so Blair sat opposite him on the couch.
After a few minutes he snapped out of it and noticed her, "Hey sis, come sit with me." Blair slid over next to him and laid her head on his shoulder. After a few minutes, Elijah spoke, "Blair, are you ok... I mean with everything that's happened the past few days?"
"Surprisingly, yes. I know I should feel bad and I know it's supposed to be wrong...but it just feels so right. Granted it was a bit awkward when dad joined us, but really? Even that's ok."
"Well, if you're sure." With that Elijah began to feel one of his baby sister's titties through her flimsy top, teasing the nipple through the material.
