The Lustful Villain: Every Milfs and Gilfs are Mine!

The irony was not lost on Iris as she found herself standing in the dimly lit corridor leading to the guest wing. She had intended to retrieve a spare set of training linens from the storage closet nearby, but her feet had betrayed her.

Her body seemed to have developed its own malevolent intelligence, dragging her toward the one place she knew she should avoid.

She knew their patterns. She knew that despite the rigid discipline of the Nightwing household, Rex and Diana often found moments of illicit connection in the middle of the afternoon moments that defied the schedule of training and duty.

Usually, Iris would be occupied with drills or reports, safely insulated from their intimacy. But today, she had finished early.

And today, fate was cruel.

As she approached the guest room, Iris froze. The heavy oak door wasn’t fully latched; it hung open by a mere two inches, a sliver of amber light spilling out into the hallway like an invitation to her own destruction.

Iris should have turned away. She should have fled.

But her feet remained rooted, and her breath hitched as she leaned forward, pressing herself against the cool stone wall to peer through the crack.

Her heart stopped.

Diana wasn’t wearing her usual commander’s uniform or even her soft linen robes. Instead, she was clad in something absurd and devastating: a black lace bunny outfit, complete with satin ears that bobbed as she moved.

Iris felt a surge of hot shame; she recognized that outfit. She had purchased it months ago, a secret, impulsive gift intended for Rex, a fantasy she had never found the courage to present.

To see it on Diana felt like a violation of her own private thoughts.

"You look ridiculous," Rex’s voice rumbled from somewhere inside, though it lacked any real bite. "Like you’ve wandered off from some tawdry tavern."

Diana let out a throaty, playful laugh that made Iris’s stomach flip. "Oh, hush..."

"Aren’t bunnies supposed to be cute?" Diana’s voice took on a teasing, sultry edge. "Besides, you know what they say about bunnies; they’re in heat all year round, right?"

"Ready to fuck anywhere, anytime~" She paused, her tone dropping to a husky whisper. "Just like you."

Rex let out a deep, genuine laugh that reverberated through the door. "A pig costume would’ve worked too, if we’d had one."

Iris watched, paralyzed, as Rex moved into her field of vision. He wasn’t wearing his armor; his shirt was unbuttoned, revealing the hard planes of his chest.

His large hand reached out, not to touch her waist, but to wind around the twin tails Diana had tied in her hair. Though her hair wasn’t particularly long, the way he gripped the small ponytails forced her head back, exposing the pale column of her throat.

"These twintails really are great though," Rex murmured, his thumb brushing against the sensitive skin behind her ear. "Makes you look almost innocent."

"Thank you," Diana breathed, her eyes half-lidded with desire as she leaned into his touch.

Then, the pretense of conversation evaporated, replaced by something primal.

Iris watched as Rex’s mouth crashed against Diana’s. The sound, the wet, hungry noise of their lips meeting, seemed to amplify in the quiet hallway.

Iris’s own mouth went dry, her pulse thundering in her ears like war drums. She saw Rex’s hand slide down from Diana’s hair to the small of her back, crushing the lace against her skin, pulling her flush against his hardness.

A soft moan escaped Diana, a sound of pure, unadulterated surrender, and Iris felt it like a physical blow to her own groin.

"Rex... oh god, Rex," Diana gasped as he began to trail kisses down her neck, his teeth grazing the spot where her pulse fluttered.

Iris couldn’t look away even as her eyes burned. She watched as the clothes were shed with frantic, clumsy hands.

The sounds became more graphic: the rustle of fabric hitting the floor, the creak of the bedframe as Rex lifted Diana onto it, and then the unmistakable, wet slap of skin meeting skin.

"Fuck, Diana," Rex growled, his voice stripped of all civility. "You’re driving me insane."

"Then do something about it," Diana challenged, her voice breaking into a high-pitched whimper as Rex entered her. "Please... now."

Iris pressed her forehead against the wall, her eyes squeezed shut, but the images remained burned behind her eyelids. She heard everything.

The rhythmic, punishing thud of the headboard against the wall; the guttural, animalistic grunts from Rex as he drove himself into her; and Diana’s voice, no longer the composed commander, but a woman reduced to raw sensation.

"Yes! "Right there, ah! Rex, please!" Diana screamed as he hit a sensitive spot, her climax building in audible waves. "Harder~! "Oh fuck, give it to me harder!"

The sounds were overwhelming: the wet squelch of friction, the ragged breathing of two people lost in each other, and the occasional sharp cry of pleasure that sounded almost like pain.

Iris felt tears pricking her eyes, not from sadness, but from the sheer, overwhelming intensity of the voyeurism. She was witnessing a level of connection she had forbidden herself from ever seeking, a raw display of need that made her own loneliness feel like a gaping wound.

Every moan from Diana felt like a taunt; every growl from Rex felt like a promise she would never receive. She stood there in the shadows, a broken assassin listening to the symphony of someone else’s ecstasy, drowning in the bitter irony of her own desire.

...

Minutes bled into what felt like hours for Iris, though she knew it could only have been a fraction of that time. She remained frozen in the darkness, her breath shallow and controlled, terrified that even the slightest exhale would betray her position.

The sounds coming from behind the door had shifted from the frantic energy of initial conquest to something deeper, more rhythmic, and infinitely more devastating.

Inside the room, the air was thick with the musk of sweat and sex. Diana was no longer straddling him; she had been turned over, pressed face down against the rumpled sheets.

Her hips were arched high, presenting herself to him in a position of complete vulnerability. Rex was positioned behind her, his powerful thighs bracketing hers as he drove into her with relentless, punishing strokes.

Iris watched through the sliver of light as Rex reached forward, his massive hands sliding beneath Diana’s torso to grip her wrists.

With effortless strength, he pulled her arms back behind her back, pinning them against the mattress. He held them aloft like reins, using them to leverage her body upward, tilting her pelvis to meet every thrust.

Thwack. Thwack. Thwack.

The wet, meaty sound of his cock slamming against her swollen folds echoed off the stone walls. Each impact forced a guttural moan from Diana, her face pressed sideways into the pillow, her hair a tangled mess of gold across the sheets.

"Fuck, Diana," Rex grunted, his voice thick with exertion, his muscles rippling with every thrust. "Grabbing you like this... holding your arms like handlebars... it gets me so fucking hyped up."

He let out a rough, breathless laugh that sounded dangerously close to a predator’s growl. "Feels like I’m riding Lily."

Iris felt as though she had been doused in ice water. Her heart stuttered violently.

’Lily?’ The mention of Diana’s younger sister in the middle of this was jarring, almost sacrilegious, but the casual way he compared the two sensations made Iris’s stomach churn with a complex mix of disgust and arousal.

"Don’t you dare," Diana gasped out between ragged breaths, her voice cracking as Rex drove deeper, hitting her cervix with a force that made her whole body shudder. "Don’t you dare bring up my little sister right now..."

"This... this is about me... I’m the one taking this!"

"I’m the one you’re inside." Her hips bucked involuntarily against him. "Focus on me, Rex!"

Rex let out another booming laugh, the sound vibrating through the door and into Iris’s very bones.

"Hahaha, look at you," he teased, his pace quickening, becoming more aggressive as he felt her climax approaching. "You’re getting all jealous... Just like Iris."

Iris flinched as if he had struck her physically. The name felt like a curse.

She pressed her back harder against the wall, her face flushing crimson in the darkness. She felt exposed, stripped bare, as if he could see her standing there in the hallway, hearing her own traitorous arousal building despite the pain.

A wave of intense shyness washed over her, a humiliating, childish feeling that had no place in the mind of a killer. She felt like a child caught peeking through keyholes, small and worthless.

"Iris has nothing to do with this," Diana whined, though the whine quickly dissolved into a high-pitched keen as Rex shifted his angle. "Ah! Oh fuck, Rex, right there—yes!"

The rhythm accelerated. The bed creaked violently, the wood protesting the force of Rex’s movements.

The sounds became a chaotic symphony of lust: the wet slap of flesh, the guttural grunts of Rex’s exertion, and Diana’s voice escalating from moans to desperate, uncontrolled screams.

"I’m... I’m close, Rex, please, I can’t—AHHH!" Diana’s back arched so violently her spine seemed ready to snap.

Her grip on her own wrists slackened as her muscles convulsed around him. "I’m cumming! Fuck, I’m cumming!"

"Cum for me then, Diana," Rex commanded, his voice dropping to a primal register. "Take it all."
