Hi everyone! This is my first fanfic ever so I would greatly appreciate it if you would review it so as to help me become a better writer!

Also, Frank doesn't get as much love (nor smut), so I figured it'd be nice to write an entire story featuring him! And his many adventures of sex to come in later chapters. So without further ado, here's my first fanfic ever!

A quick note! This story will feature Frank getting together with all of the main males of the HoO series. So after this chapter, it will be Frank/Percy, followed by Frank/Nico, then Frank/Leo, and then finally Frank/Jason. If I feel like continuing after I get done with those, the pairings will be threesomes, maybe foursomes, and maaaybe a fivesome. I may repeat pairings though too! Hope you enjoy!


The Gift of Mars

Chapter 1. Frank Gets Down By Himself

It was nighttime on the Argos II. Everyone was peacefully asleep in their rooms. Everyone, but Frank, that is. He was sitting in the crow's nest, bored out of his mind.

"Stupid Leo and his dumb working machine thing,"Frank muttered to himself. Leo had made a bet with Frank two days ago, saying that if his newest invention worked, Frank would take the watch for three weeks. Seeing as the so-called "invention" was made out of scraps, and was leaking oil, Frank thought there was no possible way it would work. His reaction when it started to move was priceless.

"Have fun up there, gorilla boy," Leo taunted as Frank started to climb up the mast. So there he was. Alone in the crow's nest. For the next three weeks. There was no sound except for the wind, as the ship flew across the sky. The bickering between Mars and Ares had miraculously ceased for the night. Not one mention from either telling him to kill Leo for winning the bet. Frank sat alone in silence.

He was only slightly hoping something would attack, anything to relieve his boredom, but unfortunately, the skies were clear. There were no signs of anything. There were no clouds, no landscape, just an empty sky.

Eventually, the sun started to rise. Hazel would be up by now and getting ready. That meant his watch was over. Frank started down the mast, and head to the showers. He didn't really need one, but his eyes were dry after being awake all night, so might as well just clean all over. As he made his way to the shower, he crossed the dining room to get a drink.

On the floor, in the corner, was the ghost king himself. Nico was sleeping with his head in his arms. Even when Percy and Annabeth were in Tartarus, Nico didn't sleep in Percy's room. Now with them back, he seemed to avoid Percy at all costs. Nico shivered slightly, but did not wake. Seeing this, Frank quickly got a spare blanket and wrapped Nico with it. When the blanket was over Nico, he snuggled into Frank's body; a small smile on his face. Frank blushed slightly, but allowed for Nico to stay for a little while.

After a couple minutes, Frank gently got up. Nico frowned and shivered at the loss of warmth, and quickly pulled the blanket closer to him. Frank left and continued on his quest for the showers. When the warm water hit him, he let out a groan of relaxation. Frank watched as the water dripped down his body, cascading into the little ridges of his abs.

If there's one thing that I can thank my father for, it was this blessing, Frank thought. He ran his hands along his torso, still not really believing that it was real. Well, that and finally shutting up. Frank started to massage his chest, feeling every muscle underneath his fingers.

He let out a groan as his fingers ran over his nipples. Frank started to gently play with them with his left hand as his right hand moved downward, going over each bump of his abs. He still couldn't believe that this was his body. Everything felt so defined, and tight. It was something he had to get used to.

His hands' movement across his body, added with the heat of the water hitting his back, caused his cock to stir. Frank spread his legs a little more for balance, and slid his hand to his hardening member. His breath hitched as he grabbed hold of his penis. Frank slowly started to jerk off, while still rolling his nipples with his left hand.

Frank stopped playing with himself in order to grab the bar of soap. He felt his cock and balls bounce around as he took the small steps to acquire the soap. Frank rubbed the soap over his chest, spreading the suds over his pecs and nipples, then to his abs. He took the time to make sure each of the ridges of his abs was covered in suds, before swirling around his bellybutton. He reached out his left arm, scrubbing the bar under his pits. He raised his right arm, and repeated the process before continuing on his body.

Passing his dick, he scrubbed down his legs. Bending back up, Frank took the soap, and started to rub it in circles over his ass, making sure every inch of the wide expanse was covered in suds. Soon, both cheeks were soaped up. With his right hand, he spread his cheeks and started to soap up his crack. Running the bar up and down, Frank took his time to cover its entirety. Feeling his asshole, he gently circled the entrance with the soap. He let out a loud moan, when the bar slipped inside a little.

Frank gripped his penis, and rubbed soap over the hard length with his right hand. He cupped his balls with his left hand as he stepped back into the spray and started to pump his cock. Frank let out loud moans as he jerked himself off. Thank gods Leo made the rooms sound proof. He played with his heavy ballsack, rolling them with his fingers. Precum started forming on the tip of his cock. Frank felt his balls tightening, so he quickly sped up his right hand. Letting loose a loud moan, Frank came all over himself. Two big spurts landed on his chest, with the rest slowly trickling onto his abs and bellybutton. As his cock softened, the remaining cum dribbled into his pubes. He quickly washed away the cum from his body.

Frank shut off the water and dried himself. He wrapped the towel around his waist, and stepped out of the shower. He searched for his clothes, but could not find them. "Really? Gods damn it," Frank said out loud. Making sure the towel was securely around his waist, Frank stepped into the hallway; his face pink. He made a quick dash to his room, ensuring that nobody saw him in this state of undress.

He made it to his room, opened the door, and quickly stepped inside. Frank was breathing heavy after making such a fast run.

"With how fast you ran, you'd think someone was chasing you!" a voice said. Frank turned around to see where the voice came from. In front of him, there was an intimidating tall man. He wore black jeans, combat boots, a leather jacket, and a bulletproof vest. Attached to his thigh was a hunting knife, and he had a baseball bat on his back. On his scarred face, were dark red sunglasses.

"Who are you?" asked Frank, his face pink.

"You mean to tell me you can't recognize your own father, boy?" the man said. His sunglasses grew brighter in his slight anger.

"Mars?" Frank's mouth dropped in surprise. "I thought you were more of the: wearing military uniforms of different countries kind of guy. Not… all of this," he said while he gestured to Mars' outfit.

"Yeah, well I am. Just right now I'm kinda Ares at the moment. Same thing though!" Ares said. Suddenly he doubled over in pain. He flickered for a moment, before standing up again. This time he wore what appeared to be wearing a general's uniform.

"Uh, what just happened?"

"Listen, Frank. It's taking a lot of power to keep us from arguing right now, and even more so being physically here right now, so I'm going to give you the short story." Another flicker of pain. "The thing is, you're praetor now. You need to learn how to give orders. We can't have the children of the Big Three always saving the day. See my daughter, Clarisse, she was a war hero. Took down a drakon single handedly. Mighty warrior that girl is. Anyways, me and my girlfriend, Aphrodite, had this idea. We give you this blessing from the both of us, and you become a better praetor from it. Do you accept?" His form flickered once more.

"That was a lot of information to process," Frank replied after a couple of seconds. "Why would you and Aphrodite want to give me a blessing? Didn't you kind of already give me one?" he said as he gestured to his bare torso, still slightly wet.

Ares/Mars flickered again before speaking. "To make you a better praetor! You didn't get chosen for this job, you had it handed to you under ridiculously special circumstances. You've got to be trained. Seeing as how we're in the middle of a war, there is no time for actual training, this blessing will help you learn faster. Do you accept?" He asked again.

"Let me think about this for a moment!" Frank answered, sitting down on his bed. He spread his legs, before realizing he was only wearing a towel, and that his father could be seeing his junk right now. Frank quickly closed his legs, his entire face a bright red.

"You shouldn't be so shy about your body, Frank," Mars said. "That blessing I gave you earlier was supposed to make you proud of who you are as a warrior. Seeing you now though, makes me see you haven't exactly learned the lesson. So you'll accept this new blessing—a gift more like it!"

Mars snapped his fingers, making Frank get up from the bed.

"What? I did not agree to thi—" Mars snapped his fingers again, silencing Frank. The sunglasses grew bright again, and when Mars snapped his fingers one more time, Frank's towel unraveled and fell to the floor. Frank's cock and balls jiggled at the sudden exposure.

Frank's entire body was soon blushing. When the towel fell, he moved his arms to cover his penis, but he was stopped. "Uh uh uh! This is meant to help you become more comfortable with your body." Mars said as his sunglasses grew bright once more. Frank found he couldn't move his body at all. His arms were stuck to his sides, his junk completely on display. Mars flicked his finger, and pushed Frank onto his bed.

A pink-ish red aura glowed around Frank. He found his cock hardening for the second time that day. Frank was blushing furiously. This cannot be happening His erect penis started to leak a final snap of Mars' fingers, Frank right hand started to move. His hand gripped the shaft and began pumping rapidly. His left hand moved down and behind his ass. With his thumb and pinky, he spread the cheeks apart.

Using his index finger, he slowly pushed the digit inside his entrance. Frank let out a loud groan as the finger pushed through the ring of muscles. He stopped jerking off for a moment, letting his body get used to the finger. When he relaxed a bit, he found himself pumping his shaft once more as he stuck another finger inside his entrance.

Frank began thrusting into his asshole with the two fingers. He let out groans of pleasure and pain as the two fingers moved in and out of his entrance. Precum was flying all over as his right hand glided across his penis, stroking rapidly. No matter how far he thrust his fingers, Frank could just not find that special spot within him. He stopped masturbating for a moment, and began lowering himself down on his fingers as he pushed them further inside. He soon found a rhythm of thrusting and lowering, picked up his hard cock, lying on his stomach and jerked off with all his might.

His fingers brushed against his prostate, and saw stars. Frank slowed the pumping on his penis, and pushed his fingers a little deeper inside of him. This time, the fingers pressed fully on the prostate, and globs of precum leaked from the tip. Frank resumed jerking off with wild abandon, thrusting his fingers deep, hitting that spot each and every time.

With one final thrust to his prostate, Frank came. He shot cum over his head, the leftovers splattering onto his face and body, The moment he came, the pink-ish red aura burst, expanding over every part of the ship. Frank came down from his orgasm, his balls still tingling. His cock began to deflate, landing on his stomach. As it shrank back to flaccid size, it smeared the cum over his abs. Frank's eyes drooped, and he quickly fell asleep. Little did he know, the best has yet to come.
