Stepping Out With Steph

Joanna, already a self-confessed cheater, seized the chance to make things up to her husband by sitting on his face while his cock filled his sister's mouth. She squirmed as he eagerly licked her sex to her satisfaction. She was looking at her husband's incestuous blowjob at Stephanie's hands, and she could not help getting turned on by the sight. It reminded her of why they had gotten into the swinging lifestyle in the 1st place: not only variety, but voyeurism as well.

The feeling of Stephanie's tongue and mouth on his cock finally pulled the semen from Blair's balls into her throat. She deliberately made a point of getting it all, and then she threw herself onto the bed, saying, "Tie me up, bro, and bang me from the rear! I am your sex slave, and this is just the 1st day of my bondage. This is what I've really wanted all of this time. Fuck my pussy, Blair, and make me your bitch!" The realization that his sister not only desired his body, but his control was a major surprise to Blair, but he was not one to complain about good news. He told her, "Change into your majorette's uniform, and report here in 7 minutes, so I can hike up your skirt and cut out the panty part of the outfit."

She swiftly left and returned with the required dress, telling him, "I am your naughty classmate, Blair, and I am ready to service your cock again. Discipline me, brother!" He took out his belt, hiked up her uniform's skirt, and struck her buttocks for a little while, until she cried with enough pain (and masochistic delight) to indicate her enthusiasm for the session. Then, he used a knife to sever the underwear section of the uniform from the rest, which caused her red cheeks to show. He grabbed and spread them, easing his way into her soaking vagina (clearly prepared by the spanking). She gasped for a couple of seconds, as his dick moved further inside her body. He followed this by sticking his fingers into her ass as he diddled her, which were joined by more digits rubbing against her clitoris and labia. He really shoved his cock into her at a mad, hectic pace, giving her no chance to catch her breath.

"Do you like this, Sis? Is this what you craved? Your brother's penis is in your pussy, riding you from behind. I may knock you up- how does that sound, Stephanie?", he taunted her. She only responded with a mute, but knowing smile, as if to suggest that she still expected to pull off the last joke of the night. When he suddenly relieved his scrotum and pulled out of her cunt, she burst out laughing. She just could not help it- it was too late to stop what she planned from happening. "It sounds wonderful, Blair, and it had better, since that is exactly what has just happened! I am ovulating, brother, and I now expect to conceive your 2nd baby!", she announced with triumph.

Blair was both shocked and furious at the fact that he had been tricked, but he was also flattered as to the nature of the trap. "Is that what you have been pursuing, big sister? You wanted to have my seed implanted in your womb. Well, now it's happened, so you can revel in your short-lived victory. What are we supposed to do with this boy or girl when it is born? It will be damaging to our careers, won't it?", he scolded her. "Oh, Blair, I don't care about that anymore! Let other people whisper, because they can't do more than gossip- you have your own company by now, so they will have to shut up and work for you, won't they? I just want the 3 of us to be a family, with you fathering children by both of us. Come on, Blair, take out your anger on my ass! Fuck my butt to your cock's content!", she replied with "naughty" delight.

He did so, pushing his dick into her rectum with little pretense of gentleness, which was precisely what she hoped for from him. He just kept ramrodding her ass for a constant, seemingly infinite time. Every thrust brought home his worry and anger at his sister's reckless, irresponsible (as he saw it) conspiracy to get pregnant by her own brother. He shoved his penis into her butt for a merciless interval. She screamed repeatedly as he took her anally, but she did not really mean for him to ease up on her rump, and he was oblivious to her noises anyway by this time. She relished the sensational agony of being sodomized and stretched out by her brother's cock. After a final push, he unleashed his coital fluid into her sphincter, making her shiver from the total ecstasy of his semen in her colon.

At this juncture, Joanna, who had been the fascinated voyeur for most of the night, dropped to a kneeling posture, dove her tongue in between Stephanie's ass cheeks, and commencing the rimming of her bottom. The sheer, exquisite pleasure of being eaten there was getting Stephanie off, to say nothing of the fact that it was her sister-in-law tasting her crack. Blair placed his own mouth inside the posterior of his wife. He managed to get a momentum going, which pressed Joanna's face further into Stephanie, making his sister even more aroused than before. The double sensory input of rimming ass while having it rimmed was having the effect on Joanna of making her sweat from the excitement of the attention. In due time, she was cumming from the feeling of getting it from both ends. There was no doubt now that Stephanie had emerged the winner of the contest of wills, and that she would get to stay with the couple permanently as their shared slave, which was her plan from the beginning. Big sister had it all figured out from the beginning, all right, and it was working to a tee!

As Blair's dick recovered, he went over to Stephanie, sat on the bed in front of her, and put his manhood between her tits, rubbing it against her breasts in a frantic motion. This pleasant surprise made her squeal with total enjoyment of what her younger, albeit grown-up, brother was doing to her bosom. When he got into a rhythm of fucking her breasts, she lost all of her self-control, because this kind of mammary manipulation was an all-new sensation, for which she was just not braced. As he shot off his next load, she motioned for Joanna to lick it off her boobs, and so horny was Blair's wife, that she went along with the plan, ingesting the salty sperm of her husband to her ravishing fulfillment. Needing to get him hard at least once more, the girls went down on him, taking turns with his cock and balls. 

They then traded his cock between their pussies and asses, switching back and forth, with the idea that the constant change should make his erection last a while longer than otherwise. Stephanie had discarded her uniform by this point, and when he got ready to empty his balls, she and Joanna held out their hands for the cum. They caught it to the last drop, and proceeded instinctively to rub it all over each other's bodies and their own. There was so much semen that it covered much of their flesh as they smeared the cream on it. The last trick of the night was for Blair's viewing pleasure, as Joanna and Stephanie ran their tongues over each other's cum-bathed bodies, licking it off to their mutual satisfaction and happiness.

"So, this is what you had in mind, is it Stephanie?", Blair remarked when he recollected himself. "Well, brother, you have to admit that I succeeded, didn't I? You don't really want to leave me out of your sex lives after night, do you, guys?", she tartly replied. "You have us, there, Steph, but just remember this: we own you from now on, because you want us so much that you'll do anything to have us, and you have proved it!", Joanna warned her. Blair backed her up with a nod, but Stephanie exulted rather than wept at this news, telling them, "Now, you guys, hasn't been obvious that I'm a submissive at heart, anyway? I am your property, I agree, and I will use that to get laid as much as possible, since both of you are dominants, and you need a complement to that, so you can't resist a slave girl, can you?"

After that night, Stephanie was a permanent member of the household, servicing both Blair and Joanna as they needed it, and the rest of the week, aside from the "Stepping Out" nights, didn't seem as relatively boring anymore, as they were always stepping out anyway- with Steph!
