Richard was left stunned as his partner shed his leather jacket. "G-Gavin, you—"

The brunet placed a finger against the android's lips to keep him quiet. With eyes locked on his counterpart, the young sergeant soundlessly backtracked towards the stereo system. He licked his upper lip before choosing a hypnotic tune from his playlist.

The android watched with an intense expression as his partner raised the volume until the bass of the chosen song sent thumping vibrations throughout the apartment. After taking a moment to analyze the song, Richard deduced it to be Weval's Gimme Some—a rather sensual tune to lose oneself in.

There was no verbal exchange between the pair—only the continuous buildup of sexual tension filled the room. Gavin gazed at his fiancé with a flushed face and lidded eyes as he navigated back towards the android.

RK900's head followed the brunet's slow movement as if under a spell. He scanned the shorter man from top to bottom, noting the officer's hardened nipples peering through his grey t-shirt. The machine swallowed as he felt his processors heat up. "A simple 'yes' would've sufficed, Sergeant," Richard jokingly stated with a smirk while instinctual desires brewed from within.

The brunet huffed as he removed his shirt and let it fall to the ground. He didn't bother indulging his counterpart in smug conversation; all he wanted was an outlet to release his excitement. "You know," Gavin began while approaching his partner and pressing against the couch, "It's a good thing Fowler gave us a couple weeks off," he brought his legs onto the sofa and straddled RK900, "Because I want you to fuck me till I can't stand anymore," he breathily expressed with searing hot cheeks.

Richard's eyes snapped open as the officer's request caused his internal units to immediately reach dangerously high temperatures. It was almost enough to send the android over the edge and lose his composure. He was so conditioned to the brunet's typically timid and shy sexual behavior that the blunt demand nearly caused Richard's components to melt completely. RK900 was brought back to reality however, when he felt hands working to unbuckle his belt.

Gavin's heart was racing—his thoughts were suffocated by the sound of his heart beating against his chest. He successfully removed the android's belt and threw it to the floor. The officer was overjoyed and overly excited to the point where he'd lost the filter he so avidly used when speaking or performing actions. His thoughts were instantly verbalized into statements his partner would've never expected to hear coming out of the hot-headed cop. "I want to feel you inside me," Gavin pressed a hand against Richard.

The machine couldn't keep up with the officer's demands. His processors were working overtime and yet, he found himself at a loss for words.

The ardent desire to feel RK900's hands trailing down his body overcame any remaining dignity left in the young sergeant as he grabbed the android's hands and brought them to his chest. "I'm begging you," the brunet pleaded with arched brows, "Touch me."

It was the way in which the officer delivered the last phrase that caused Richard to ultimately succumb to the burning need to make Gavin cry hot tears. He wanted to hear the sergeant's adorable whines and hoarse groans. He wanted to see sweat bead against the officer's scarred skin. He wanted to make Gavin entirely his.

"Ah—nh!" the brunet flinched as he felt Richard's fingers press into his chest.

RK900 let out an exhilarated breath as he watched his partner bite down on his lower lip to stifle his soft moans. "I didn't know you were sensitive here, Gavin," the android slid his tongue over his teeth as he cupped the officer's pecks, "I've always admired your broad chest."

"Uhn," the sergeant shut his eyes while his body began to tremble. He whined as the machine felt up his shoulders and inched down his collarbone.

The android leaned in and pressed his lips against Gavin's right nipple while he played with the other using his fingers.

Gavin sharply inhaled as he felt his partner's teeth press down on his skin. "Oh f-fuck," he barely voiced while Richard continued working on pleasing the officer.

The machine spent a few more minutes tending to the brunet's chest before pulling away to eye a breathless Gavin. Richard let out a satisfied whistle as he noted the officer's swollen nipples and the numerous prominent bite marks riddling his partner's broad pecks. "What a gorgeous view," he stated with a lustful cadence.

"M-more," the disheveled sergeant begged, "Please," he pulled on his fiancé's necktie.

Richard slightly reeled forward as a result of Gavin's tugging. His gaze drifted from his partner's cherry red cheeks to the shining band which snuggly fit around the officer's ring finger. The android took a moment to engrave his life's happiest moment before scooping up his horny counterpart and cradling him to the bedroom.

RK900 gingerly placed Gavin on the bed before bringing both hands to work at getting his tie, jacket and long sleeve off. As Richard removed his white and black clothing, he felt Gavin's hands unzip his slacks. His thirium pump worked at an accelerated pace as the anticipation to make love began eating away at him.

The brunet gripped both the android's briefs and pants and dragged them a bit below the thighs. Gavin let out a huff as he stared at his partner's hardened member then wasted no time in taking Richard's cock in his mouth.

"Mhn," RK900 shivered before pressing his lips together to adapt to the sudden wave of pleasure that overwhelmed his senses. He let out a pleasurable sigh as he ran his left hand through Gavin's brown locks and continued unbuttoning his dress shirt with his right. "Gavin, that feels incredible," he praised in a guttural tone.

The brunet quivered at the complement. Goosebumps prickled his skin as he felt Richard's member swell in his throat. The officer whined while beginning to bob his head up and down his fiancé's thick cock; saliva dribbled down the corner of Gavin's mouth and eventually, his neck.

"Nh," Richard winced before shutting his eyes. A breathy grunt escaped the machine's lips as Gavin began picking up the pace. The android reveled in pleasure while removing his shirt and dropping it to the floor.

The brunet forced more of Richard's cock down his throat which nearly caused him to gag, but RK900's lustful expression was enough of a motivator to sit through the pain and continue giving head. The young sergeant moaned as he felt his counterpart's cock twitch in his mouth.

"G-Gavin," Richard pressed his teeth together, "Ngh," his nose crinkled.

The officer immediately pressed his knees together. The reactions from the machine caused a sudden rush of blood straight to the brunet's cock. He let out sounds of discomfort before bringing a hand to cup his pants while the other assisted in pumping the android's dick. Gavin's cock was straining against his briefs and causing discomfort—he was yearning for friction. The cop unintentionally began gyrating his hips in an effort to get off.

Richard relaxed his features with a slow exhale as he realized his partner trembling for more. "I can see you're quite excited yourself," RK900 glanced at Gavin's hand which was working to remove his jeans. "Allow me to help," the machine gently pulled the officer away and pushed him further onto the bed.

Gavin was breathing heavily, trying to catch his breath from deep throating his counterpart. He stared at his hungry fiancé as his chest quickly rose and fell.

Richard removed his slacks and briefs completely and pushed them out of the way before leaning into Gavin.

"Nh," the sergeant drew his brows together while the android planted kisses down the brunet's torso all the way to his navel. "P-please," Gavin's voice cracked.

RK900 glanced at his partner in surprise.

"I can't wait anymore, please" the sergeant's eyes filled with tears, "I'm gonna pass out."

Richard had finally reached his limit. He tried to cap his intense desire to ravish the brunet but it finally boiled over. "God, you're too much," the machine speedily pulled down the officer's jeans and boxers—almost tearing them in the process. RK900 flipped Gavin over on his stomach and pulled the cop's rear closer.

Gavin's breath hitched in his throat because of his fiancé's sudden actions.

"I won't stop until your hips are numb," the android declared while slapping the brunet's ass.

"Ahn!" the young sergeant whined as he brought a hand to cover his mouth.

Richard raised a brow before a nefarious smirk sprouted on his face, "Someone's a tad bit masochistic."

"I'm no—uhn!" Gavin yelled as he felt Richard's hand strike down once more. "Sh-shit," the officer arched his brows as his ass started to sting.

The machine watched through hooded eyes as he spanked his fiancé once more, eliciting sweet moans from Gavin. He couldn't take it anymore; he wanted to drill the brunet deep.

The sergeant audibly gasped while Richard tightly gripped his waist. His eyes shot open, blush further spreading to his ears and nape as he felt something intensely pleasurable yet alien from behind. "Oh fuck," Gavin began to shake violently. He finally realized that he was getting eaten out and the warm sensation he was feeling was in fact Richard's tongue entering in and out of him. "Ngh," the officer held his breath to prevent anymore lewd moans from escaping his lips. Sweat began dripping down his brow as he felt the android pick up the pace. "R-Richard," Gavin could barely speak.

RK900 stopped what he was doing to glance at his blissful partner.

"Fuck me already."

Gavin had just breathed life into the machine. RK900 wasted no time in heeding his fiancé's words as he dragged the smaller man closer.

"Hn," the brunet drew his brows together before eagerly biting down on his thumb. His heart rate skyrocketed as he felt Richard's cock rub against his ass. He looked over his shoulder at his blue-eyed counterpart who was as turned on as can be.

"You've made me the happiest being alive, Gavin Reed."

The sergeant's eyes widened at his partner's sudden declaration. Before he had the opportunity to react, he froze; his body was entirely overcome by overwhelming pleasure and pain. Gavin shamelessly let out cries his fiancé had never heard of up until this point. "Oh G-God," he whispered as he felt Richard enter him. "AH!" he yelled, his head bucking back while his counterpart thrusted into him with powerful force.

RK900 let out a satisfied grunt as he filled his fiancé to the hilt. "I won't go easy on you this time," he pressed Gavin into the bed before firmly gripping the officer's arms. "I'm going to make you cry," he huffed before pushing the brunet onto his cock.

"Fuck!" the brunet's voice strained. Ecstasy trailed up his body as Richard used the officer's arms to rock back and forth.

In an effort to further please his counterpart, RK900 released Gavin's wrists and instead, brought his hands back to the young sergeant's hips. He took a breath before giving it hard to his fiancé.

"Uhn—nh! Shi-ahn!" the brunet couldn't even think anymore. The sensation of the machine continuously entering in and out of him was too much to bear. He was at the mercy of the android. The sound of skin slapping and squelching caused Gavin's nipples to harden as the lewd noises sent shivers up Gavin's spine.

RK900 ran a hand through his hair while picking up the pace and ramming into his sweating, trembling partner. He wanted to see the brunet's face and thus, without pulling out, he flipped Gavin on his back—they were now in a missionary position.

There was a momentary pause before Gavin pulled Richard in for a heated kiss.

The android's soft lips locked with his partner's while he continued drilling deep into the officer.

"Mhn," the brunet moaned with arched brows as he felt RK900 mixing up his insides. Then, a numbing sensation nearly caused the sergeant to faint.

Richard noticed the sudden change in his partner's facial expression and stopped thrusting. "Gavin?" the machine cupped his fiancé's cheek, "What happened?" he asked in a worried tone while eyeing his barely conscious partner.

"Y-you…something weird…" was all the cop managed to utter.

"What did I do? Something painful?"

Gavin slowly shook it head.

"Then what is it? What happened?"

"D-do it again," the officer pleaded, "You hit something…and I nearly f-fucking fainted."

RK900 took a moment to process his counterpart's words before he lowered his lids. "I see," he chuckled, "I think I may have hit your prostate."

"A-again," Gavin begged, "Please," he was breathless, "Make me cum."

The flushed officer's request repeated about ten times in the android's head. "You're going to be the death of me," Richard declared before indulging in his partner's pleas.

"Uhn! R-Richa—ah!" the officer arched his back and dug his nails into the sheets around him as his chest bounced up and down with each consecutive thrust.

Both men were quickly approaching climax.

RK900 thrusted a few more times into the brunet before Gavin winced and convulsed, "I—fuck! I'm gonna cum! I'm gonna f-fucking cum!" his eyes watered.

"Mh," Richard grit his teeth, "I'm getting there myself," he grunted.

The sergeant climaxed first as hot tears streamed down the corners of his eyes. He tilted his head back and rode his orgasm, shaking violently while ribbons of cum shot onto his stomach.

RK900 tightly closed his eyes as he felt Gavin clamp down on him. He rammed into his counterpart once or twice more before ultimately losing control and filling his fiancé's insides.

Both men breathed heavily as they recovered from their intense love making session.

A few seconds passed before Richard tucked hair behind the officer's ear. He smiled at his tired counterpart, "So it's a yes then?"

Gavin chuckled as he turned to gaze at the android, "Yeah, tin can. It's a yes."

There was a pause before the brunet glanced at a jubilant Richard. The brunet's eyes widened before he curled his lips into a charming smirk.

"Richard Reed…yeah, that's got a nice ring to it," the sergeant smiled.
