Although Rob couldn't see his sister through the blinds of Scott's office, he knew what she was doing in there. There was almost no sound outside in the pre-dawn chill of the morning, and from his vantage point in the pooled shadows behind the auto shop, Rob could hear the cries of the three people inside.
It seemed Amy had some mischief of her own going on.
After Rob's brief conversation with her the night before, Rob had watched Amy closely. He'd followed her from the house to the auto shop, sticking to the shadows, being as quiet as he could. She hadn't spotted him, and he'd waited across the street until Scott's car parked out front. At that point, he'd already put it all together.
Amy was fucking Scott behind her mother's back.
Not only that, but they'd brought another girl in already — Sadie, Scott's young secretary or office gopher or whatever. The thought left him stunned and aroused in equal measure. Apparently their mother had put Amy on the fast track to complete depravity.
Rob felt a pang of jealousy — three women in the last week alone, a mother, a daughter, and the daughter's hot best friend. What the fuck had that guy Scott done to deserve such a bounty?
In the dark, Rob was determined to get some of those riches for himself before it was all over. He could play the depravity game, too.
The cries inside the office reached a crescendo. Rob hadn't yet risked trying to peek through the tiny gap in the blinds — he was terrified of getting caught — but the sounds inside were too enticing to resist. Standing on his tiptoes, he craned his neck to look inside.
Through the narrow slit of light between the blinds and the window sill, Rob saw the three of them in the office — all completely naked, their bodies gleaming with sweat. His sister was on her knees, her elbows propped on the leather couch, while Scott fucked her from behind. Sadie knelt next to him, one hand on Amy's bare hip, the other clutching Amy's hair, holding her in place so Scott could have his way with her.
Rob watched his sister, fascinated. Always expressive, her face displayed every emotion that crossed it; pleasure, disbelief, a hint of sweet humiliation. Rob felt his erection press against his jeans, and himself felt a faint pang of shame. He wasn't sure why — he'd already seen his mother naked only the day before, a situation he'd deliberately orchestrated. Feeling ashamed at this point felt like closing the barn door long after the horses were gone.
But still, it was his little sister.
Amy suddenly stiffened, letting out a series of loud, hitching gasps that ended in a sound much like a sob. Rob suspected she had just come. Scott, who from the sound of things had come at least once or twice already, slowed his thrusts, drawing a few more moans from Amy before pulling out of her. Amy collapsed limply to the couch, while Sadie pressed her lips to Scott's in a passionate kiss.
Scott sat down on the couch, and Sadie crawled into his lap, drawing her bare knees up under her and draping herself across his chest. The three of them began to chat, with elated looks, on what had just happened.
Rob couldn't hear what they were saying through the window, and the sudden intimacy of it bothered Rob. He crept away from the window, shifting his erection in his jeans, and began the long walk back home.
The morning air would do him good. He'd have time to think about how he was going to use this new information. With a little finesse, in a day or so he'd be completely in charge of this demented game his mother had started.

The sun was up when Rob got home. He laid down on the couch and waited for Amy to arrive. After about twenty minutes, he heard the back door open, heard her pad quietly to her room. A few minutes later, she crossed the downstairs hall to the bathroom, and he heard the shower start running. It wouldn't do to come home smelling like sex with her mother's boyfriend, Rob figured.
Amy must have been tired or distracted or both, because not only did she neglect to lock the door, but she didn't even close it all the way. Rob lay in in the dark, biding his time for a few minutes, and then got up and walked to the bathroom.
He slipped through the open door and watched his sister's naked form through the translucent shower curtain. He couldn't see much, but then he'd already seen Amy about as raw and vulnerable as anyone was ever likely to. Rob leaned against the counter and enjoyed the sight all the same.
The shower stopped, and Amy stepped out. Her eyes bulged when she spotted him. She squeaked and reached for the bath towel, clutching it to her wet body. Rob saw a glimpse of taut, pale flesh before she hid it away.
"Rob! What the fuck, get out of here!" Her voice cracked with dismay, the way it had when they were both young and he'd tease her by taking away one of her dolls.
"Sorry," he said with a smile. "The door was unlocked."
"Get the fuck out of here!" she said. "I'll tell Mom."
"I don't think you will," Rob said. "I know where you went this morning, Amy."
He wouldn't have thought it possible, but Amy went even paler. The color drained from her cheeks, and she stepped out of the tub, dripping. "What are you talking about?"
"I followed you to the auto shop," Rob said casually. "I saw your little threesome with Sadie and Sc—"
Amy lunged at him. For a moment he thought she was going to attack him, but instead she slammed the bathroom door shut.
"Keep your voice down," she whispered fiercely. "Mom will hear." From this angle, Rob could see the naked curve of her waist and hip. She caught him admiring it and flinched back, still clutching the towel to her chest.
"Mom's still asleep," he said. "She won't hear a thing... at least not right now."
He watched as Amy's face fell. Her expression was like a rabbit caught in a snare. "Rob, please don't tell Mom about this. She'll freak out."
"I'm sure she would," Rob said. "She's freaking out already. See, she told me how she set you up, how you and her and Scott all got together and had your nasty little incestuous tryst."
"Ugh, shut up," Amy said. "It wasn't like that."
"What was it like?"
She glared at him. "You wouldn't understand. You make it sound all seedy and horrible."
"It is seedy and horrible. And you made it even seedier by fucking Scott behind Mom's back."
Seeing that he wasn't going to budge, Amy let some of the tension in her body release. Slowly, she began to dry her shoulders and neck with the towel, giving Rob more glimpses of her flesh.
"She started it," Amy said. "It wasn't my idea, it was hers."
"That's bullshit," Rob said. "It was your idea, she just made it happen after she found out about it."
Amy looked at the floor with a guilty expression. "Look, please just don't tell her, okay? Yeah, it's screwed up and weird, but Mom likes Scott, I don't want them to break up."
Rob laughed. "Well, isn't that considerate of you."
"Shut up."
Rob licked his lips. "I won't tell her. If you do something for me."
Amy froze in place, her wet hair falling around her face. "Oh, God," she said.
"Don't worry, it's not that." Not yet, he thought.
"Then what?"
"You're going to break up with Ian."
Amy furrowed her brow. "Why?"
"Because Mom started this whole travesty to keep you two from each other. She didn't want you fucking up your college career by being preoccupied with sex. Granted, it turned out to be the world's stupidest idea and one of the biggest backfires of all time, but still. You don't love Ian, and he doesn't love you. End it. Mom will be happy, you'll be happy, we can all put this prurience behind us."
And start a new kind of prurience, he thought.
Amy sniffed while she considered it.
"Fine," she said at last. "And when would you like this to happen?"
Rob ignored her sarcastic tone. "Friday night. And I'm going to need you to do one more thing."
Amy rolled her eyes. "Jesus, what's that?"
"Even though you probably won't be, I need you to act like you're upset about the breakup. You know. Turn on the tears, let Mom comfort you. She'll like that."
Amy eyed him suspiciously. "Why?"
"Just trust me."
"I don't, but whatever. Now will you get out of here so I can put some clothes on? I know you're getting all horned up looking at me."
"What if I am?" He reached out and stroked her bare, wet waist with two fingers. She watched his hand, but didn't pull away, even when he flattened his palm against her hip.
"Pervert."
Rob scoffed. "I'm the pervert? I'm not the one diddled our mom."
"Shut up!" she squeaked, and made to throw a makeup case at him. Rob fled.

Three days a week, Lauren worked at Arthur's, a tiny art gallery in the heart of historic downtown — that was what the marketing copy said, anyway. In reality, it was more like a graveyard than a gallery, and Lauren's job more like a security guard than a curator or impresario.
No one came in to the glass-front shop to look at the modern art paintings and sculptures, and Lauren spent most days either at the counter or in the back office, surfing the Web and thinking of the meager paycheck she earned. At least they let her come to work in casual clothing.
It was on a sunny, cloudless Wednesday afternoon that Rob swaggered in, not even sparing a glance at the art as he walked up to the counter.
Lauren felt dread and embarrassment surge through her. The memory of their encounter in the kitchen, now two days past, still haunted her. The relief she'd felt unburdening her soul to him, the terror when she realized he intended to use the knowledge against her, the awful arousal when he'd taken off her clothes and she'd knelt naked before him.
She couldn't lie to herself about it — Lauren had fully expected her son to pull his cock out and order her to suck it. The vision had unfolded vividly in her mind's eye several times since then.
Even worse, Lauren was fairly certain she would have done it, if he'd told her to. Not because she had to — even though Rob now had enough dirt on her to crash an entire barge of drama on the shoals of her life — but because she wanted to. Because what she'd done with Scott and her daughter had unleashed a thirst for taboo that made her limbs quiver. She'd wanted it not in spite of it being seedy and squalid and wrong, but because of all those things.
Lauren remembered feeling terrified that she'd end up going down on her own son, then feeling disappointment when it hadn't come to fruition. All her feelings in the meantime amounted to a cacophony of guilt and confusion, and she'd avoided Rob since then.
Now he was here, putting his elbows on the counter.
"Hi, Mom," he said with a grin.
