She's not Cortana. That's what he has to keep telling himself. Cortana was never this bubbly, this… cute. He had to keep saying that, even as he kept trying to fall into old habits again. The Weapon was not Cortana.
Unfortunately for him, that led him to ignore an obvious fact.
She was not Cortana. She was naïve and inexperienced, but she was just as bold, if not more so, than Cortana had ever been, and what she did with it was… He surprising. Really surprising. He had, up until a point, been thinking she'd simply saw him as a friend.
Then, after all was said and done with the Harbinger, and once Esparza was out of their immediate vicinity, John had went to sleep.
He was laying on a bed, in a stark, plain room, the sort of room he'd bunk in, when she'd entered. All human-colored, pink skin with chocolatey-brown hair.
The Weapon gave him a smile, as she walked over, touching his chest. "I've got something for you, Chief. Call it a… hero's reward, hm?"
The Spartan, before he could even really argue, was frozen still, watching as she got on her knees in front of him, and undid the button on his pants. She slipped his boxers down, looking upon the large, thick shaft that sprung free.
Licking her lips, she went in, slowly teasing, pressing a series of hot, quick kisses up and down his length, the rod stiffening in her hand as she moved, stroking up and down slowly, the soft skin of her hand encapsulating it. Her eyes flickered up to look at him, twinkling, as she slowly opened her mouth, and gently took him in.
John, for his part, could only stare in surprise. What had gotten into her, he wondered?
…as she bobbed up and down, looking at him with those wide doe eyes of hers, he very quickly decided to let it be. This was a dream, no harm could come from it, right?
John quietly grunted, resisting the urge to buck and thrust into her mouth, as one of her hands slipped down the front of her uniform pants, the tight fabric being displaced as her fingers worked on herself.
John groaned under his breath, as he felt the pressure building within him, as the Weapon sped up her own fingerthrusts into herself. Before long, John felt himself burst, right into her mouth.
She smiled, swallowing down the first load of his seed, coaxing out another spurt, and another, before she became overwhelmed, and she pulled herself off, breathing heavily, before swallowing.
The Weapon gave him a smile, before she began to straddle his lap, rubbing the soaked crotch of her pants into his bare cock.
John looked down, in rapt attention as her pants seemed to dissolve into smoke, and she lined up his stiff erection with her moist entrance. She sunk down on it, letting out a low, blissful moan…
And then, John woke up.
The SPARTAN shot upright, looking around confusedly.
"Whoa, whoa, Chief, calm down!" The Weapon gasped in his mind. "What's wrong?"
"I…" John blinked, frowning. How to tell an AI that lived in your head you were having sex dreams about her? He'd had those, of course, he was human at the end of the day, but no one had ever asked him to elaborate… "Nothing." He said at last after a long pause. "It's nothing."
"Well, looks like you had a pretty good dream." She remarked, "Your brainwaves are all over the place."
"…I suppose." The Spartan awkwardly shrugged.
"Hm…" The Weapon hummed, clicking her tongue. "Well, I guess it doesn't matter, in any event. I've got a little present for you… Think of it as a hero's reward." She did a little drumroll, "Ta-da!" She put up an icon of the grappleshot on his HUD. "I figured out how to eliminate the cooldown on your equipment!"
John blinked, shifting slightly.
"Hey, are you okay?" She asked worriedly. "I'm showing an increase of blood flow in your body, particularly near the lower regions… You didn't get hit by anything, did you?"
"It's nothing," John shook his head, laying back down after a moment. "…Just don't use the phrase hero's reward for a while, understand?"
