Dr. Caspian Rayne had been passed over by every major lab in the city. Five rejected patents. Three publicly mocked proposals. One divorce paper signed, unsigned, signed again. His peers had gone on to design defense suits, kinetic armor, anti-radiation drones. He'd been left alone with a basement full of prototypes, a bitter taste in his mouth, and one last vial glowing softly in its containment tube.
Project EROS-9. It was supposed to be a neuro-enhanced soldier serum--designed to increase strength, reaction time, and obedience. It had tested well on rats. Mostly.
The serum had an unintended trait: it didn't bond to the bloodstream--it bonded to behavior. The first sexual climax after injection created a permanent neurological lock to the first person the subject received semen from. It didn't matter if they were a scientist or a soldier. Whoever filled the subject first, owned their pleasure system forever.
Caspian had rewritten the logs, buried the behavioral data. But he knew the truth. This wasn't a soldier serum. It was a sexual reprogramming agent. One dose. One fuck. No way back.
Still... he had a plan.
His wife, Elise, had been distant for months. Cold. Critical. She barely touched him anymore. He thought she was tired. Overworked. But last week he found unfamiliar underwear stuffed in the laundry she never folded. And tonight she came home late, makeup smudged, hair freshly showered.
He asked where she'd been. She said nothing. He asked again. She said "don't start."
Caspian didn't say another word. He offered her tea, a foot rub, and told her he wanted to show her something he'd been working on.
Elise looked bored when he showed her the serum. "Is it another rejection?" she asked.
"No," he said, smiling. "It's something different. Something that might save us."
"Us?" she scoffed. "Caspian, it's not science we need."
"No," he said. "But this might help."
She shrugged.
He slid the needle into her neck before she could ask what it did.
She gasped, slapped his arm, then swayed. "What the fuck, Caspian--what did you--"
Her eyes fluttered. Her nipples stiffened. She clutched her thighs together.
"I feel... hot..."
Caspian guided her gently to the bedroom. "It's okay. You'll feel safe soon. I just need to... seal the connection."
She groaned. "I feel like I need to be fucked... Caspian... I..."
Her pupils were dilated. Her breath came in shallow gasps.
Caspian reached for his belt.
But before he could unbuckle, his phone buzzed.
A text. From her. Sent to someone else.
Come over now. He's still in the lab.
He turned his head. The window. A silhouette. A heavy landing. Boots. Someone had just landed on the back porch.
She laughed, drunk on heat. "You're too slow, babe," she whispered, just as the sliding door opened.
And in stepped a man.
A tall, muscular, glowing figure in matte black armor trimmed in white--a visor shaped like a solar eclipse.
Sol Sentinel.
Caspian froze.
Elise rolled onto her knees, crawling toward the hero like a starving bitch in heat. "Silas," she moaned. "I need you--now--before it goes away..."
He looked confused, but not enough. He unzipped.
She opened her mouth.
Caspian shouted, "No--don't!"
Too late.
She wrapped her lips around the head of his cock, moaning like her brain had just rebooted. Her whole body pulsed. Her skin flushed. Her tits visibly swelled under her shirt. Her hips twitched, thighs spread. She came. Hard.
And as Silas groaned and unloaded into her throat, her mind surrendered.
When he pulled out, Elise collapsed onto her elbows, tongue hanging, cum dripping from her mouth. She looked up, dazed, smiling like a fucked-out porn star.
"Silas... I feel so perfect..."
Caspian backed away in horror. She didn't even look at him. She crawled to Silas, nuzzling his leg.
"Need more... fill me again... I'm your slut now..."
Silas looked stunned. "What the hell did you do to her?"
Caspian's voice was hollow. "I invented her."
The hero zipped up, eyes wide. "She said... she wanted it. She didn't tell me--"
"It doesn't matter," Caspian snapped. "You're bonded to her now. She'll never want anyone else. Her body belongs to you. Her brain... her orgasms... every drop of cum she produces is calibrated to your pleasure."
Elise moaned. "Please... I'm ready again... use me..."
Silas looked like he wanted to vanish. But instead he knelt beside her, brushing her hair back.
"She's really gone, isn't she?"
"She's not gone," Caspian said. "She's just... evolved."
Silas stood. "Then we need to talk."
The two men sat in the lab while Elise crawled between their legs, licking at Silas's pants, moaning, fingering herself and whining like a bitch in heat. Caspian didn't stop her. He couldn't. He was hard. Furious. Jealous.
But mostly hard.
"I didn't mean for this," Silas said.
"Neither did I," Caspian replied. "But you came inside her. And now she's Velvet Halo."
"Velvet what?"
"It's what the serum does. It rewrites everything. She's optimized for sex. Seduction. Bonded arousal. The name just fits."
They watched her bounce on her knees, begging to be used.
Silas exhaled. "She can't be a wife anymore. Not like this."
"No," Caspian said. "But she might be useful. A distraction. A tool. She's built for pleasure. And you--you're a symbol."
Silas looked at him. "What are you proposing?"
"We use her. We use the serum again. This time... carefully. Pick our target. Build a team. You do the fighting. I make the weapons. She keeps the villains wet and stupid."
