Chapter Two: In the Gym

Palmer leaned against the door of the gym and smiled, her dark black undersuit hugging her curves tight. She bit the bottom of her lip as she watched John on the bench press, his muscular body rippling with every rep. Already she could feel her crotch moistening at the thought of what was to come.

He hadn't noticed her yet, and discretely she checked the hallway behind her. Seeing no one, Palmer slowly slid the door shut and locked it behind her. The Commander's hips swayed side to side as she marched towards her intended prey, the Master Chief still totally oblivious to her presence, earbuds drowning out any noise of the approach.

John was laying flat on his back on the bench press, his eyes entirely focused on the bar as he pushed the weights up and down. Two-hundred pounds at a hundred reps, and he was just starting to feel fatigued. Suddenly his vision was blocked, Palmer's predatory face appearing above him.

Before he could make a move her lips were on his, her tongue searching his mouth hungrily. For a moment John was paralyzed, his mind racing as Palmer's aroma completely surrounded him. After several seconds John finally came to his senses. He hung the bar up with a loud clang, grabbed both sides of Palmer's face, and wrenched her lips off of him.

"What are you doing?"

Palmer laughed as she popped the headphones out of his ears. "That's what are you doing ma'am." She moved in for another fierce kiss, biting and swirling her tongue against his. She grinned internally as John began to kiss back. Their tongues fought for supremacy, but Palmer easily won that battle. She needed to set the terms of this little encounter early on. She was, after all, his commanding officer.

This time she slowly pulled away from him, leaving John breathing heavily. Palmer moved to whisper into his ear. "I bet Cortana has never kissed you like that," she said, biting his earlobe.

"No," John gasped. His normally calm and measured mind was in a deep swirl of contradictory emotions. His loyalty was to Cortana, but at the same time his body was experiencing a level of arousal that he had never thought himself capable of. Far greater lust than Cortana had ever been able to elicit. It was almost like he was on a drug, the euphoric high clouding his normally sound judgement.

"We can't do this," he said breathless.

"We can," Palmer said as she trailed kisses along his neck. "We are."

John shook his head. "Cortana…"

Palmer giggled evilly into his ear. "Oh poor little Cortana." Palmer stretched out her hands and raked her finger nails along John's chest. The Commander just barely heard a low deep involuntary moan escape from John's lips.

"She doesn't deserve you," Palmer whispered. "And I'm going to show you why."

Palmer pulled away, leaving John's line of sight. When she returned her undersuit was completely gone, her gloriously tight fit body on display for John to see. The body of a warrior goddess. The body that only a Spartan woman in her prime could have. The body that John had secretly been eyeing for months now.

The Master Chief was completely transfixed.

Palmer knelt gracefully down between his legs, but even in this position of supposed submission, Palmer still generated an aroa of complete commanding dominance.

Her neat manicured nails dug into John's skin as she toyed with the hem of John's shorts. He offered no resistance as Palmer pulled them down, his erect member popping free when she did. He was so hard that it hurt.

Palmer grabbed his cock and began stroking up and down. Not in the slow, timid way that Cortana had done with Fred, but in a swift determined fashion that exuded confidence.

Palmer knew that she was hot. Knew that she was desirable. Knew that she could have any man she wanted, and she wanted John. Nobody would stop her. Not even him.

Palmer began licking up and down his member, her tongue swirling around ever square centimeter of his shaft. She gave his cock a few more strokes, and then took him into her mouth. John's eyes widened as he watched her take inch after inch of him, his cock sliding into the back of her throat without so much as a gag. At last her head reached his pelvis, and Palmer brought her mouth back up again.

She continued bobbing up and down in a rhythmic fashion, her hand squeezing and playing with his balls as her tongue worked wonders on his shaft. Her ponytail bouncing up and down as her head bobbed.

John's mind went blank, all thoughts of Cortana momentarily vanishing. Tentatively he reached out a hand to touch her, only to have it brutally slapped away.

"Were you given permission to touch?" Palmer said, releasing his cock from her mouth. Her voice was full of command, and John felt his body reflexively go rigid.

"No ma'am."

"Didn't think so," Palmer said. She gave his cock one last lick before going back to rhythmically stroking it.

"Cortana has never done that for you has she?" Palmer asked, already knowing the answer.

"No," John said, his voice strained, his hands gripping the bench underneath him.

"No what?" Palmer barked.

John's body went rigid again. "No ma'am."

"Hmmm," Palmer said. She swirled her tongue around the head of his cock, deliciously teasing him. "Poor Cortana," she said. "Always in need of rescuing. Always in need of a strong man to save her." She grinned up at John. "But we both know what kind of man you are. You don't give orders, you take them. A woman like Cortana would never be able to satisfy you. To give you what you really need. But me?"

Palmer deep throated him again, and this time John did groan out loud.

"I'm not on any birth control," Palmer said, her nails digging into John's inner thigh as her other hand continued to stroke. "I've been fucking Lasky for months," she said matter of factly. Under normal circumstances this revelation would have stunned John, but now he was in such a lustful haze that he could just barely focus on her words.

"I haven't let him cum inside me though," Palmer said, flicking her tongue along the tip of his cock. "Spartans should only have children with other Spartans. Strong, superior children." Her mouth broke out into a wide hungry smile. "And that's exactly what you are going to give me."

Palmer moved with a grace and swiftness that only her class of soldier could possess. She straddled John's hips, but did not take him inside her pink folds. Instead she grinded the outside of her pussy along his shaft, stimulating her clitoris and leaving John intensely aroused and frustrated.

"This is your last chance to say no," Palmer said, steadily grinding her pussy against him as her hands went up to play with her breasts. "Last chance to leave and go back to Cortana. Once your cock goes inside me your mine. Once you fuck me you'll never be allowed to fuck anyone else ever again. Your cock will belong exclusively to me."

John swallowed hard. It truly was like a drug. As if there was something, some force overriding his normal morality.

Palmer would have had an ample word for it.

Lust.

"So what's it going to be Chief?" Palmer asked, her pussy moving with ever increasing speed. "Yes, or no?"

"Yes," John breathed before he could stop himself. "Yes ma'am."

Palmer grinned in triumph as she lifted her hips, lined John's cock up, and slammed down.

She bounced up and down on him, her hands going crazy on her breasts, pinching and tweaking her nipples as loud moans escaped from her lips. Her pussy gripped John's cock like a vice grip. He had no idea how she could possibly be so tight and warm. It was nothing sex with Cortana, who never made any noise except for small petite moans. Palmer's face was primordial and animalistic. Like a lioness who had finally captured her pray. Her ponytail was only hanging on by a thread, her normally pinned up hair threatening to break loose from the sheer ferocity of the sex.

John watched as his cock slid in and out of her. The sight was mesmerizing. He reached out to touch her hips, to feel her tight ass with his own rough hands.

Again his hands were slapped away, and Palmer descended upon him. She pushed her breasts right up against his chest, a strong hand grasping his throat. She whispered ferociously into his ear, "What about asking permission to touch did you not understand?"

"Nothing ma'am," John gasped, his breath slowly being cut off as Palmer tightened her grip.

"If you want love you can go back to Cortana," Palmer sneered. "I am your commanding officer. I own you." She began rocking her hips again, stimulating John even as he fought for air. "You're not equal to me. No man is. I am your goddess, and you will treat me like it. Is that understood?"

"Yes ma'am," John groaned, Palmer giving him just enough air to voice his compliance.

"Good," Palmer said. She leaned back away from him, but still kept her hand firmly on his throat. "Now let's make sure you remember it."

Palmer began fucking him, her pussy tightening around his cock even as her fingers tightened around his neck. She fucked him like a woman possessed.

John could hardly breath, and darkness was slowly creeping into the corners of his vision. It was the most intensely erotic thing he had ever experienced.

Suddenly Palmer threw her head back, her body contorting and a loud cry coming out of her pink lush lips as an orgasm ripped through her. Her vaginal muscles contracted and she slammed herself all the way down, taking John in as deep as he could go.

John's fingers tore at the bench underneath him, and he gritted his teeth as he felt cum rocketing out of his cock deep within Palmer's womb. An explosion of colors rocked his vison. It was the most intense orgasm of his life, and Palmer felt spurt after spurt of warm cum deliciously fill her womb.

Palmer let go of John's throat, her nails leaving behind deep indentations in his skin.

John gasped for air as he looked up at his goddess, her body covered in a shiny layer of sweat, her breasts perfect and inviting.

"Permission," he gasped. "Permission to touch ma'am."

Palmer smiled. He was finally learning.

"Granted Master Chief."

John sat up, his hands moving to cup her firm ass. His mouth covering her breasts.

"There you go," Palmer cooed at him, running her fingers soothingly through his short brown hair as John feasted. "I've seen you looking at them. I know how much you've wanted them."

Palmer then grabbed a fistful of hair and pulled his head roughly back. She stared deeply into his eyes.

"I'm going to give you one more chance," she said. "I'm not your girlfriend and I'm never going to marry you. I'm never going to love you." She began to move her hips and down, John's cock sliding in and out of her. "But what I am going to do is fuck you. I am going to use your body as I see fit, and you will worship me in return."

She smiled at him wickedly. "Who fucks you better? Me or Cortana?"

"You," John said, his fingers digging into her ass as she slowly continued to fuck him.

"Will you ever fuck her again?"

"No ma'am," John said. He was beyond any morality at this point. Would have said anything Palmer wanted him to say.

"Good," Palmer said. "Now fuck me. Fuck me like you never fucked her. That's an order Spartan."

John willingly obeyed. He was a good soldier, and he would not disappoint his superior.

He grabbed Palmer fully by the waist, and the Commander braced herself on John's shoulder's. John held nothing back. Did not go soft as he always did with Cortana, and neither did Palmer. It was visceral, and the weight bench underneath shook and threatened at any moment to break as Palmer was repeatedly slammed down on John's cock, only to be lifted back up again.

Palmer continued to use her pussy muscles, squeezing John's cock with all her might with ever stroke, their hips colliding together with enough force to injure a normal human.

The Commander arched backwards, the full glory of her body on display for John to see, his eyes transfixed on her breasts as they repeatedly bounced up and down to the rhythm of their intense fucking.

John felt his balls begin to tighten, and the pace became quicker and more frantic. Palmer leaned back into him, kissing and biting his neck. Leaving bite marks and hikeys all over him.

"Do it," she growled at him. "Do it. Knock me up. Give me what you'll never give her."

John groaned into Palmer's shoulder blade as his cock erupted deep into her womb, Palmer cumming with him soon afterwards. Somehow he seemed to cum more than he did the first time, spurt after spurt flowing into her in an endless stream.

Palmer relished the feeling, a warm glow surrounding her as John filled her with enough of his seed to make it nearly impossible for her not to get pregnant. Their genes mixed together, and Palmer relished the victory. He truly was hers now.

Palmer kissed her ferociously, and John did the same in return, their hands clawing and grasping at each other's bodies without any regard to the bruises and scratches they left behind.

After a while Palmer whispered in his ear, "My room."

"Yes ma'am," John said. He knew an order when he heard it.

Within moments the two were dressed and out the door. To anyone walking by it would simply have seem like the two had just had an exceptionally vigorous workout.

Less than a minute after John and Commander Palmer had left, and extremely flushed and fulfilled Cortana poked her head out of the sauna door. Her and Fred had been too busy fucking each other's brains out to notice what had transpired between John and Palmer, and Cortana breathed a sigh of relief when she saw that John had left.

Despite what she had said to Fred in the heat of the moment, she was not yet ready to break it off with Chief quite yet. At least not until the right moment when she would be able to put him down gently. He deserved that much.

The two emerged from the sauna drenched in sweat but fully clothed. Fred came up behind her and hoisted Cortana into the air, causing her to giggle playfully.

"My room," Fred said. Cortana responded by kissing him passionately. They continued to make out as Fred carried her to the door, only setting her once they were ready to go through.

The door slid shut behind him, but the smell of intense and passionate sex lingered on well afterwards.
