Somnus Nox Series Mind-Control Erotica #4

“That was good, huh?” I ask my son, Ian, as we leave the gym. I clap his shoulder, making sure to grasp him tightly. “You feelin’ the adrenaline?”

“Damn right,” he breathes, laughing. “That was pretty good.”

“Yeah?” I grin. “Tell me what’s going on. Any changes going on?”

At that, he starts to blush, swallowing. “I guess more testosterone,” he admits. “I’m more… like, I don’t know.” He laughs awkwardly. “I mean, the muscles are definitely coming along. I don’t have noodle legs anymore.”

I snort as we get into my car, all sleek leather seats and a black exterior. Fucking big, fucking expensive, a goddamn luxury. Just because my boss, Kyle, won’t fully indulge in the luxuries I do, doesn’t mean I won’t.

I drive off the gym lot and head home, which is less than 10 minutes away. I live in a gated house on the outskirts of the city. It’s a large area of land with a white-bricked mansion fronted by a large courtyard where five cars are already parked. It is all mine, all pristine and beautiful.

Ian chugs the last of his water. His dark hair is slicked back and shoved off his face. He has his mom’s features, all long dark lashes that make him look like a pretty boy.

“You found a way to blow off that steam?” I ask just as we turn into the driveway after a long bit of silence.

“I… I’m working on it,” Ian mutters. He brings a fight to the gym-always wanting one more rep, always going the extra mile on the treadmill, always fighting to impress me. As he should.

I smile, turning away from him to get out of my car. See, my son is special. My second born, my only son… God, the plans I have for him.

“Good,” I answer. “It’s the next phase of my goal for you.” When he doesn’t answer, I continue, “C’mon. Let’s go see what your sister’s up to.”

We get out of the car, and as soon as I hear the water from my outdoor pool, I don’t even bother going into the main house. I key in the back gate code and wait for the click. I let us both in through the gate, going straight for the beer cooler.

The back garden boasts a massive pool, sun lounging area, a barbecue pit, and a sitting area with lights wrapped around a pergola my wife built.

“Think fast,” I call out to Ian, tossing him a beer bottle.

“Have fun at the gym?” Connie realizes we’re there and comes to the edge of the pool, folding her arms on the edge. Ian cracks open the bottle as I sit with him.

“Sure,” Ian mutters. “Dad had me on twenty kilos.”

“Damn,” Connie whistles. “In no time at all, you’ll actually see an inch of muscle somewhere.”

“Shut up and swim,” he snaps, drawing his legs up to his chest. In his thin black gym shirt, I have to admit Connie’s right. I’ve started Ian slow and light on his workouts, and we go five days a week, but he’s really not seeing a whole load of progress.

He will, I remind myself.

Ian watches his sister as she swims laps in the pool, her ass lifting above the surface every now and then in a dolphin-like stroke. Her hair is a sleek sheet behind her as she cuts powerfully through the water. Her mom always loved swimming.

Ian sips his beer enthusiastically, gulping it down.

“Hot, son?” I tease.

“Yeah,” he mutters, not taking his gaze off Connie.

She splashes over to the edge of the pool, rising up like a damn siren. Water pours off her as she pushes up, easily hoisting herself onto the concrete edge before standing. Her eyes close, and she pushes her wet hair from her face. I take the opportunity to watch my son-my son who is watching my daughter.

It’s not like I haven’t noticed it before, the way his eyes track her whenever she comes down in something slightly revealing, or too short, or wears a shirt without a bra on. I notice him doing the same as me; we both watch her like she might be ours.

The only difference is that Connie is mine and has been mine for the past year. Only she doesn’t know it.

His thighs, pressed to his chest, can’t quite conceal the boner he’s popped, but I’ve noticed that before, too. I bite back a laugh. I can’t blame him; Connie’s gorgeous, only two years older than him, fresh out of college, and utterly living her most glamorous, gorgeous life with every beauty expense she demands covered by me. I’ve had more than a taste of her tight body, honed by her own workouts. Her skin, glowing with both false and a natural tan, complements her wide, round eyes that are the color of my morning coffee.

The bulge in Ian’s shorts only grows the more Connie toys with her hair now, her black bikini leaving nothing to the imagination. Her thong bottoms frame her hips, and the mound hidden beneath is visible through the flimsy fabric. Her nipples press against the bikini top that wraps around her neck, the tiny triangles covering… not a whole lot.

Her body is a row of muscle and gorgeous, unblemished skin, spotted with freckles.

“Hey, weirdo,” Connie calls, and Ian jumps, his gaze clearly gone too far south to notice her eyes opening. I watch Ian’s face flush. “Quit the staring. Don’t you get enough watching porn?”

“I…” He trails off, his hands falling into his lap to hide his boner. “Um-”

The blush on his face deepens, and Ian scrambles off his sun lounger, racing into the house. I growl as I glare after him. I’m trying to teach that out of my damn kid-this shyness, the hunching run, the lack of confidence. If he wants something, I want to teach him to take, not to run. I won’t have a son with low self-esteem, especially not when it concerns family.

Connie teasing him whenever she catches him staring doesn’t help.

“You know, you could be better about the teasing,” I tell her as she sets herself up on the sun lounger Ian just vacated, stretching like a cat in the sun. “Build him up a little, help his confidence. He doesn’t need you putting him down. He’s workin’ hard.”

Connie scoffs and gives me that look, the typical attitude-ridden one every father gets from his daughter when she’s of age enough to have her own mind. She shrugs, turning to face and look up at the sun, her eyes closed. I let myself indulge in the sight, fighting off my own arousal.

Her breasts push up with how she lets her arms rise above her head, and I can’t help but wish I could fold myself over here right there and lick up her stomach. I want to suck the soft skin that she slathers in coconut oil, and want to have her all to myself.

But an idea has been occurring to me lately.

Something in darker depths than I’ve already ventured.

I keep thinking of my boss, Kyle, and his words. My girls, side by side, loving on each other. There was no better feeling than that, not for a father.

I was hardly surprised when I learned that Kyle fucked around with his twins, and I’m definitely not one to judge. My eyes flicker over Connie, the curve of her breasts, the parting of her thick, muscled thighs, the dark suggestion of hair just visible on either side of her bikini panties.

What will Ian do if given the opportunity to have his taste of Connie?

If he can let out all those sexual frustrations on his sister, the very person who teased him endlessly?

My next step is for Ian to lose his virginity-and who better to help him through the process than his father and sister?

Tonight, my boy becomes a man.

I shoot a text to Alex, the programmer of Somnus Nox, the thing that will let my son and daughter bond tonight.

You wanted that data on a woman and two men? You’ll get it tonight.

I smile to myself before relaxing further into the sun lounger.

“How’s Mom getting on with Grandpa and Nana?” Connie asks later that evening as she settles into her seat in the cinema room, burrito clutched in her hand.

“Good,” I tell her. “She said your grandparents are happy with the prices they’re getting.”

“I can’t believe they’re actually retiring to Florida,” Ian says. I shrug.

“They’ve worked hard enough for a good life out there. Your mom’s just making sure they get the best prices for what they own.”

I swallow, thinking of my wife out in New Hampshire with her parents. If I had any shred of decency left, I’d feel bad for only thinking of her absence as an opportunity. I’ve been sneakily indulging in my daughter behind my wife’s back for almost a year-for once, I won’t have to tiptoe around my own pleasure.

The movie begins with a blaze of music and narration. Ian’s focus immediately hones in on it. He’s always been a movie nerd, that sort of kid in college with Back to the Future posters on his walls. Connie was always different, more confident.

I’m only half-watching the movie, more so keeping an eye on my children as we eat burritos and fries. Usually, I’ll cook for them a full gourmet meal, but tonight, my focus is elsewhere.

Halfway through the movie, I can’t help but spy on Connie, who’s spending more time on her phone than watching the movie. She doesn’t even look up at the shirtless scenes of the main guy as he zip wires over treetops.

I wish I knew what sort of brainless guys fills Connie’s thoughts.

“Hey,” I whisper to Ian. “Come over here a second.”

Connie’s too engrossed in her phone to notice us moving away. Confused, Ian follows me as I press a pair of earbuds into his hand. I’ve already come prepared.

“What-”

“Put them on,” I instruct my son. “And go back over there. Don’t sit down.”

There’s a moment where his confusion wins out, and he thinks about pressing further, but ultimately, I’m his father. He does as I tell him. He presses the buds into his ears while I pause the movie. Again, Connie’s unaware, completely focused on her typing.

I keep an eye on her as I connect my phone to the cinema room speakers and pull up Somnus Nox. I scroll through the function menu, hesitating before I select sleep mode. Seconds later, a soft sound filters into the room.

“Dad, what-”

“Shush,” I tell Ian, my eyes on Connie. She looks at us, confused for a moment, and then her body gives out. She slumps into her chair, her head lolling to the side. Her phone falls from her grasp. From beneath the control center where I paused the movie, I take out a blanket from the cupboard. It’s thick and fluffy, comfortable enough. I spread it over the floor in front of where Connie’s slumped.

From my pocket, I pull out a watch. I eye Ian as I fasten the watch onto my daughter’s wrist.

He’s speechless, slack-jawed in wonder, in confusion. His eyes still dance over his sister’s body.

“I-what the fuck just happened?” Ian asks in a rush. I’m too busy rearranging Connie onto the blanket, letting her body limply lay back. I kneel next to her, looking back at my son.

“You want to be a man, don’t you?” I ask him, cocking my head. He nods eagerly, his eyes unable to stay off Connie for too long. I already know what he’s thinking because my own thoughts used to linger there for so long. Except I did something about my desires, as perverted as they were.

“Why-why’s she asleep like that? And what was the music?”

“Magic,” I mutter sarcastically.

“Is it to do with your job?”

“Yes.”

I notice Ian moving closer to that confirmation as if he realizes that he's not alone if he pursues anything his wicked little brain is conjuring.

“And-and you’ve done this before?” Ian asks, sliding forward another inch. He looks almost okay in a baseball jersey and jeans, if not for the hunched shoulders and posture that reeks of insecurity. But he’s coming closer, he’s giving in, and it’s not proving to be as difficult as I thought.
