Mark pov:

I sighed for what must have been the tenth time. Looking at the blueprints for the new weapon. No matter how hard I tried, there's still no way that I've found. To were I can find a way to make it work without draining the robots power.

Ryan asked me to work on a new weapon that could help the team in underwater fights.  If that were to ever happen in the future.  Drawing up the blueprints took a months, mainly because I couldn't find a good design and model.  Once that was down I needed to make sure the parts I needed were waterproof. 

Not that hard to do when you have two science freaks handy. But now I can't seem to find a power source stable enough and powerful enough to  power it.  So I'm back at square fucking one!

"Dammit"!  I shouted, throwing the blueprints and any other tools off the table onto the floor. Flopping my arms and head onto the table.  This was becoming so annoying. I'm Mark Walker I should easily be able to do this no sweat!

I bet Leo could have found a power source a day after getting all the parts he needed

Leo. I've been having dreams about him.  His callused hands running up my body. His tender lips kissing my neck as he pounds me from behind. Though that'd probably never happen.

"Somebodys a little stressed. How about I fix that",  Leo whispers into my ear. A jolt ran through my body.  As I shot up,  spinning towards him. He places both hands on my knees, slowly opening my legs placing himself between them.

What the heck is happening!?

"W-what". My voiced cracked, something its never done before. A groan escaped my lips As he slowly rubbed his knee against my clothed cock.  He smirked at this.

"Come on Mark. I see the way you've been looking at me recently. Of course, your little diary did help alot to". 

A look of horror crossed over my face.  That was in the bottom of my tool desk! No one was supposed to know about that.  Now he's seen all the dirty thoughts I have about him. This is just great.

"And you know what. I'd like you being bent over while I pound into that little boy pussy of yours.  While you call me daddy, as well".  He began trailing kisses down my neck.

Neck kisses were one of my biggest turn on's and right now he was taking full advantage of that. I couldn't help the slutty moans that spilled from my mouth as he sucked and bit on the exposed skin. I'm sure I'll have hickeys by morning.

Not being able to resist him. I wrapped my legs around his waist, grinding up against him. Hoping to get more friction. But my clothes were getting in the way.

"So eager, aren't we", he teased. "Take your shirt off". I did what he asked with no question. His mouth attacked my hardening nipples. He sucked and licked them, slowly driving me crazy.

"Ah....hahh.", my body shivered with pleasure as Leo ran his hands up my back.  My hips bucked, rubbing our crotches together. Leo groaned as this happened. His lips met mine as we engaged in a passionate kiss. He licks at my bottom lip and I denied him access.

He squeezed my ass, making me gasp. Taking the chance, he shoved his tongue into my mouth. Exploring the warm cave. Our tongues fought for dominance, which Leo won.

A hand played with my left nipple, while another one shoved itself into my pants. Firmly grabbing my cock, slowly stroking it. My eyes nearly rolled back into my head. It felt so good. I was becoming a moaning mess and he's only used his hands.

"Look at you.  You're beautiful",  he started moving his hand faster. My hips bucked and my back arched in ecstasy. I'd never felt pleasure like this before. Sure I jerked off once but it didn't compare to this.

"AaH..hahh...s-so good", precum leaked from my cock only adding to the pleasure.

"I'm...ah..g..gonna..cum", before I could get my release he stopped his assult. Making me whine.

"Daddy, wants to give you a treat", he whispered moving from between my legs. I eyed him, as he undid his pants and briefs. leaving his thick long length on full view.  I licked my lips
, just imagining the taste of it was making me want cum even more!

"Come, show daddy what a good boy does with his treats",  Leo smirked.  Getting off the stole and onto my knees. I began sucking him off. It started off slow with him bucking his hips every now and then. Groaning as I took him deeper and deeper down my throat.  His pace quickened until he was literally face fucking me. I choked a little as his cock went deeper but it felt to good to stop.

"Ah...so..good. Your such a little minx", Leo groaned. Holding my head in place as thick cum spewed down my throat. I swallowed it. Standing up, my lips smashed into his. His hands sliding down to my pants. Pulling them down to my ankles. Stepping out of them, I was left completely naked.  

"Aah, daddy! O-oh god....Haah". I was a moaning mess as he sucked on my length. I wasn't as big as he was so taking in my whole length was easy for him. He hummed at the back of his throat, the vibrations rattled my cock making me leak more precum. He swirled his tongue around my base. Before sucking and nipping at it with his teeth.

My knees felt like they'd buckle at any moment. The pleasure I was in had me slightly drooling. "I-i'm gonna....AAah! ",  I couldn't take it anymore and released my load down his throat. He sucked me till I was dry. This was my fantasy come true.

"Lay on the work table,  my little minx", Leo ordered.  Doing as he said I climbed onto the table. Resting on all fours. There was a sharp sting to my ass as he spanked me.

"Please....I want it, please Leo", I begged.

I felt my cheeks being spread and the feeling of lips on my hole. Leo started off with gentle light kisses to my cheeks and hole. Before licking at it. I moaned as he did this. But what happened next drove me crazy. Leo began to stick his tongue in and out of me at an alarming rate. My legs trembled as he forced one of his fingers in, grazing my prostate.

"More daddy"! It became hard to hold myself up, so I laid the front half of my body against the cool metal of the table. Leaving the rest of me on full display. He kept teasing my hole for what felt like hours. I'd become a moaning mess, begging him to finally have me.

"Da...daddy, please fuck me.Oh..ah, I want you inside me so bad", I cried.

"Alright, baby. Tell me if I'm hurting you, minx". After he said that I could feel him pushing his way inside me. It hurt so much as he stretched me out. He waited for me to adjust to him. After two minutes the pain lessened.

"You, can move now". I said.

"Are you sure? " he questioned. I nodded. He began moving and god it was painful. But pain soon turned into pleasure as his thrust continued, starting off gentle and slow. His groans filled the air.

"Oh, oh daddy. Faster....please go faster"! I begged. He grabbed my hips, gripping them to the point were I'm sure they started brusing.  His thrusts came faster and harder than before. My body rocked with his thrust.

"Ah! Oh god....Leo! Leo, yes....yes..."! If this wasn't heaven I don't know what is. Having the man I've fantasized about for months, shoving his cock in and out of me....oh god, there was nothing like.

"Ugh...so tight",Leo groaned ramming himself back into me. He hit something in me, making me scream as my eyes rolled into my head. "There we go. Scream my little minx, scream for daddy". His speed picked up as he repeatedly abused my prostate. I felt like I was drowning in pleasure. A thin lawyer of sweat covering my body. My moans bounced off of every wall. 

I whined as he pulled out of me, leaving me feeling empty. My body was gently flipped over so that I was now laying on my back. My vision was a little blurred from my tears. I felt his hand caress my face. Causing me to smile lazily at him.

"Look at you. Your so beautiful Mark. I love you", he whispers. Leaning down capturing my lips in a sloppy kiss as he shoves himself back inside me. I clawed at his back, wrapping my legs around his waist. He pulled from the kiss minutes later. Attacking my neck. The room filled with a mixture of groans and moaning.

I felt my lower stomach tighten."Leo....gonna..cuum" I screamed releasing my load onto his chest. His thrust began sloppy and faster. With a groan, I felt his hot load pour into me, right against my prostate.

"What the heck"!?  A shocked pilot and friends yelled upon entering the room.
