I am sorry for the late update, I have been busy with my job lately, but now I'm able to update some stories especially this one.

Y/n POV

I couldn't believe what I was seeing. Cortana was staying in front of me with an actual physical body. I was completely amazed at what was in front of me and I was completely blow away from this sight. My A.i. begins to show off her smoothly, long slender body. My mind was blow away from her sexy blue body that I couldn't take my eyes away from her body. I watched as she slowly began to turn her body around to give me more of a look at her sexy body.

When she was fully turned around my eyes roam down her body, I couldn't help but stare at her perfect ass, it was nice and plump, and it looked very soft and squishy. I kinda wanna squeeze it and play with it.

Y/n's mind: "For an A.I. she has a very good looking ass."

I couldn't believe what I was saying, I was actually talking about my A.i. being sexy, and she's my A.I. for crying out loud. Not only that but I couldn't even figure out how it was even possible for her to have a physical body. Did Dr. Halsey give my A.i. a new upgrade or something?

If so how did she do it and why didn't she tell me so I could have been aware? And Why didn't Cortana tell me about this until now? I was trying to process this and I didn't notice Cortana shaking her butt in front of me. And I can't help but stare madly at her ass.

Third Person POV

Cortana began to shake her butt at Y/n, she was teasing him, she then turned around and she noticed Y/n looking at her butt without looking away and she smiled. Her plan was working.

Cortana: "Enjoying the view~"

Cortana shakes her butt a little as Y/n quickly looks away as he was blushing.

Y/n: "Sorry!"

Cortana walked over to him and she started touching his chest. Slowly she drags her finger down my chest while dragging it down to my crotch.

Cortana: "I don't mind~"

Her hand goes down his chest and she grips his area and starts rubbing it as Y/n gulps and blush.

Cortana: "Wanna have some fun?"

Y/n glups.

Y/n: "You sure that you wanna do this?"

Cortana: "Yes I want to. Why, do you not want to?"

Y/n: "It's not that I don't want to... It's just..."

Cortana: "Chief, listen to me, you are a great soldier and you did a lot for this universe, and for humanity. So I think you deserve to be rewarded."

She wasn't wrong about that, I have saved the universe and the world countless times, and I never usually ask for a 'thank you' in return. Maybe she was right I think I should be rewarded for all the hard work I have done over the years.

Y/n's Mind: "You know what, FUCK IT!"

Lemon starts🍋

Cortana crawls on bed over to him and kisses him while wrapping her arms around his neck, as Y/n blush and he decided to go with it, so he kissed her back and he slowly grabbed her butt, giving it a nice squeeze and Cortana moan in the kiss. Her body pressed up against his, her breasts pressed up against his chest, and the spartan moaned into her mouth.

While they were making out, Y/n grabs Cortana's ass and gives it a gentle squeeze, the young woman moans into his mouth as he squeezes her ass. It was clear that she actually liked it and he was actually loving it.

Y/n moves to sit down on the bedside, Cortana gives him a quick kiss before going on her knees, and sitting she began undoing the front of his shorts as Y/n takes a deep breath.

Then Cortana pulled down the shorts and his underwear and she saw his dick and it was big. She blush since she was now up close to his dick and then Cortana looked into Y/n's eyes before giving his dick a nice long lick.

Y/n gasps and Cortana started licking the tip of his dick making him moan a little. Then Cortana slowly started taking him into her mouth and started moving her head up and down pleasuring him.

Y/n moan feeling Cortana's mouth on his dick and it was amazing. It's been awhile since he's done something like this, he hasn't done it with any of the female Spartans because he hasn't had a lot of time she spent with any of them. He's hasn't been to hook up with anyone he's close to since he's always busy with saving the world and the universe. But he has seen some of the female Spartans naked before but tries not to make it look like he was a pervert for looking at them.

Cortana continues moving her head and down on his dick more faster. She never thought that she would be able to do this with Y/n, or that sucking him off would taste this good, and be this big because she secretly have been watching him every time he toke a shower, trying to get a good look at his sexy body and up at how big he was up close but also try not to get caught by him noticing her. But right now she thinks that she found out how to make him feel more relaxed. She was pleasuring him with her mouth.

Y/n moan enjoying Cortana's mouth and she took him deeper into her mouth. She gagged a little but didn't stop because she wanted to go even deeper. The Spartan rubs her soft blue hair to make sure she was okay and she pulled off his dick with spit on her chin and Y/n's dick was covered with her spit and Cortana cough a little bit while catching her breath.

Y/n: "You okay?"

Cortana: "Yes, I'm fine, don't worry about me."

Cortana immediately took him back in her mouth and deep throating him and moved her head up and down faster. Y/n moan and she was smiling because he was enjoying it as he grunts.

Y/n: "Cortana I'm gonna cum!"

When Cortana heard his words, she didn't even think about pulling away, but she wonders what his seed tastes like, because she wasn't a fan of enjoying the taste of the seed from the male spartans or any other male she works with but she's wondering what human seed tastes like. So she continued sucking even faster as Y/n was breathing heavily and he was about to explode.

Y/n: "Ruhhhhhhhh!"

Cortana felt his seed shooting in her mouth and to her surprise his seed was tasty. It was a little salty but a little sweet at the same time and she started a hard time to swallow it. And he did shot a lot even more then she expected.

Y/n sighs and Cortana swallows all of his seed and she pulled off his dick, then lick it cleaned, tasted the remaining of his seed because she really enjoyed the taste. The spartan groans in pleasure from the blue woman.

Y/n: "Okay that was good, I never thought you know how to do that Cortana."

Cortana: "Well that's because I have secretly been watching you while you're showering and I have watched you masturbate before."

This caused the Spartan to blush, knowing that his AI was watching him the whole time, and he felt really embarrassed.

Y/n nodded and then Cortana got up off the floor and helped him take off the rest of his clothes. Now they were both completely naked in front of each other. Cortana's breasts were pretty big, they were a perfect size for him but legs made her look even more sexy but Y/n was wondering what is she doing.

Y/n: "Cortana, what are you doing?"

Cortana: "what do you mean what I'm doing? We're continue to the main event?"

Y/n: "I mean I do but I don't know if we should do this because I don't wanna get you pregnant or I don't know if I can get you pregnant but I don't wanna take that risk."

Cortana: "Why are you worried about getting me pregnant?"

Y/n: "I'm not ready to be a father yet I'm too young for it."

This only causes the AI woman to smile more as she just rolls her eyes.

Cortana: "You shouldn't worry because I can't get pregnant."

This seems to confuse the Spartan.

Y/n: "What do you mean?"

Cortana: "You shouldn't worry because Dr Halsey designed my body to where I can't even re-produce so you have nothing to worry about."

The Spartan looks at her dumbfolding not realizing she was telling the truth. He felt really stupid for being worried about getting her pregnant.

Cortana smiled and she goes against the wall of the room placing her hands and she turns around to Y/n and she shakes her butt to him, teasing him to take her.

Cortana: "Go ahead~"

Y/n couldn't resist and he goes over Cortana, placing his hands on her nice butt, squeezing it a little making her moan, and he grabbed his dick and slowly slide it in her anus. It was really tight but he noticed Cortana was groaning in pain.

The young A.I. was new to this feeling and it was her first time as well.

Y/n: "You okay?"

Cortana: "You're a lot bigger than I expected. It's hunts."

Y/n: "You don't have to do this."

Cortana: "No I want it."

Cortana keeps groaning in pain and Y/n started kissing her neck and grabbed her breasts to get her mind off the pain and she smiled.

Cortana: "Okay I'm ready."

Y/n nodded and he grab her butt again and slowly started thrusting in her pussy, Cortana moan but it did still hurt, but it later on started feeling good and she began to moan.

Y/n was moaning like crazy, feeling the tightness of her anus, it was griping his dick so tightly it felt like he couldn't pull out.

They both moan together, Y/n started thrusting faster as he moaned feeling the tightness of her anus on his dick. He grunted as Cortana kissed him as he continued thrusting in her.

Cortana: "lie down."

Then they switch positions Y/n lays down on the bed and Cortana slowly begins to straddled him as she traced her fingers along his cock, before angling it up and allow it to prop up against her lips. Both gasped as his tip was swallowed by her, and Cortana ground her teeth as she slowly sank down onto him. Y/n whimpered and twitched as she sank all the way down onto his cock until he was deep inside of her uterus.

She planted her hands against Y/n's chest as she slowly raised herself, try not to make a lot of sound as she felt her Spartans thickness shift within her. Both of them let out a quiet moan as she slowly lifted herself up then sank onto him once more.

Slowly Cortana grinding herself on his dick and slowly began bouncing on his dick. She moans holding his shoulders and Y/n tightly holds her butt helping her bounce on his dick as he grunts. It was becoming easier to move, so she continued and settled into a slow rhythm against Y/n. Y/n grunt in satisfaction as cortana's rocking became constant, relishing in the warmth and tightness of being completely enclosed by this woman.

This is beyond anything his fantasies have ever come with the experience of sharing intends feelings with the woman he had a relationship with. Cortana moaned happily as she ground against him, and he looked up at her and smiled. Her face was flushed but she appeared more than content, panting slightly as she rocked. His eyes floated down to the sight of her breasts jiggling slightly against her chest and grinned. That was a site he never stopped looking at.

Y/n: "how're you doing?"

Cortana smiled, her blue eyes attempting to focus on him and only him.

Cortana: "I'm good. Tough at first, but this is good."

Cortana kissed him while bouncing on his dick, sticking her tongue in his mouth, as their tongues rub against each other. Y/n gives her butt a little hard slap making her moan while continuing bouncing on his dick.

After what felt like an hour Y/n was about to explode and he slowly stopped thrusting and pulled away from the kissed and looked into the blue woman's eyes.

Y/n: "Cortana I'm about to cum."

Cortana: "Do it! Cum inside me PLEASE!"

Cortana started bouncing on his dick a lot harder and Y/n grunts grabbing her butt and started thrusting they moan together and they cum together.

Y/n: "Ruhhhhhhhh!"

Cortana: "Ahhhhhhhhhh!"

Cortana felt his shooting inside her, filling her butt and Y/n moan holding her tightly as he released inside her pussy. The blue woman loves the feeling of him filling her pussy up with his seed. They kissed and made out to enjoy their time, they broke apart from the kiss. Y/n slowly pulled his dick and a little of his seed leaked out of her pussy.

Cortana: (Panting) "That was amazing..."

Y/n: "Yeah it was."

Cortana gives him a quick kiss before cuddling up to him. The Spartan pulls the covers over them as they both slowly fall asleep.
