Will has just had an explosive encounter while straddled atop his seemingly unconscious sister. His sister, Devin, meanwhile is determined not to let his sense of honor or shame stop her from getting what she wants.
***
Will and Devin finally reached home, far earlier than expected, but in good spirits. Will was convinced his sister truly had been asleep, or she'd never be holding his hand on the way back. As they reached the front door, she put her hands on his chest and leaned up to give him a quick peck on the lips.
"Thanks for the fun date little bro!"
She flashed him a heart-stealing smile as she turned to unlock the door. Will couldn't help but grin either as he followed her inside. They weren't quite sure what to expect when they got back, but it certainly wasn't the sight of their mother laying passed out on their chaise, clad only in a rumpled corset and garters, thigh-high nylons spaced unevenly. An empty bottle of wine and a tube of lube were on the coffee table. The green, cupless corset fit her like a glove and propped her tits up to an admirable degree. A large dildo and vibrator lay abandoned between her legs, and a reflective sparkle from down further revealed a jeweled butt-plug inside her as well. Her hand lay between her legs, chestnut hairs curling lightly around thing fingers as they reached for her sex. Such was Will's view.
Devin, however, was more preoccupied with the video that had been left looping on the tv. She stood transfixed with a mix of horror and lust as she watched her father tie her mother up, her ankles in the air secured to a set of posts. Belatedly she realized the camera was not mounted, but rather that there had been a second man there with her parents filming their session. She gasped as her father slapped her and her mother whimpered "more, daddy, please". By now, Will stood beside her watching events unfold with an equally rapt expression. They were becoming upset with their father, though they gathered from his awkward efforts with the slaps that she had probably requested that treatment to begin with. Steve at last ripped off his whitey-tidies exposing a dick with a warped fat head, but of perhaps four inches length. Will's brow furrowed as his sister let out an involuntary snort. They both gasped though as the cameraman moved to get a better view, several more men became apparent in the frame.
Practically before the camera could capture their Dad sliding into their mom, he groaned in pleasure as he allowed himself three quick thrusts. He seemed disproportionately proud of himself as several of the men tried to hold back their amusement. A man with a large white cock had managed to slide most of the length of it down her throat. She began patting the man's leg urgently.
"Y'all good Lise?" the man asked her as he removed the length of his cock from her mouth. She muttered something inaudible to him. The man asked her to repeat herself, laughing as he cut her off midway by roughly shoving his cock down her throat. She flipped him the bird but kept sucking. "She said you know the drill and to get back down there Steve." They watched as their dad slid between the bed and a very thick looking black cock. As he dove in to her cum-filled muff, shame and eagerness clearly writ on his face---
The scene cut away, as the movie began looping from the much more innocent beginning. Brother and sister both shook their heads as they avoided looking at one another. At some point their hands had clasped tight. They reluctantly released each other as they looked down at their mom.
"Who knew mom was such a freak?"
Will looked scandalized.
"What? I mean, unless you think all of that was only dad's idea..."
"No... but... I still love her, no matter what she does."
