Already covering two decks with their frantic fucking, cumming again and again who knows how many times (they didn't count for sure!), screaming so much that their throats (but not their genitals!) became sore, they decided to take another shower, this time in the crew quarters. Soon however Ashley leaned against the wall when James ate her ass until he pulled her onto the floor where they tried the 69 position. She was on top with her legs on both sides of Vega's head and his cock in her mouth until the frantic oral action ended with them both squirting their juices into the other's mouth.
After another quick shower, they went to the elevator again, kissing and masturbating each other. This time they left in the machinery deck, just next to the huge windows towering over the hangar. This time it was James who found himself pushed against the glass when once again Ashley sank to her knees to blow his gargantuan cock in the hope of receiving his thick gunk as a reward for a good performance. This time however he didn't stay idle, instead grabbing her head and face-fucking her so hard that if not so many rounds of oral sex before even she couldn't take it. But her moans and slutty look she was glancing at him with told him she enjoyed it as much as he did.
Looking at the door to Javik's quarter they both agreed the Prothean was too creepy even for them, but the room Diana Allers - who still remained on the Normandy in Council's attempt to make themselves look better in the public eye (especially asari and salarians, who made very questionable choices during the war) - resided in was a different case - especially as it turned out she left her camera onboard. Feeling more adventurous than ever, Williams turned it on while James set the lights and they fucked like crazy on the reporter's bed. Vega knelt behind Ashley, pulled her arms, and pounded hard, while both of them stared straight into the camera lens with expressions that could make most of the pornstars blush. Afterward, they sent the video to themselves and deleted all traces of it.
"And if there's something left," James said, "Diana will have something very special to watch" - it aroused Ashley so much that she ultimately dragged him to Javik's cabin too; after all, the Prothean would already sense the traces of their sex marathon all over Normandy - wouldn't he be offended if they omitted his quarter? There they fucked on his desk, with Williams' fingers unintentionally dipped in mysterious liquid kept in vessels on both sides of it - made to enhance Javik's psychic abilities, it enhanced her senses as well and she orgasmed harder than ever, kind of terrifying James who for a second thought he really fucked her into a coma.
But it wasn't an orgasm to end all orgasms for sure - that's why they continued. This time it was James who dragged Ashley further, toward the engine room... but then they noticed stairs leading to the lower level - and that proved to be too alluring location for their current, horny state of mind. In no time Ashley found herself lying on the stairs with Vega pounding her hard from above; the edges of other stairs should've felt uncomfortable on her back, but under such a pleasurable assault she didn't even perceive them. After her first (in this place of course) orgasm she was lifted by James and he turned them around - this time Williams' upper body ended on lower stairs than her bottom, but she just braced herself and took another pleasurable pounding. Next, vulnerable after two consecutive peaks, she allowed Vega fuck her throat when she stayed in her upside-down position but still swallowed his thick sperm with loud gulps he found sexy as hell.
Already on the bottom of the stairs, they noticed the bed set in the lower deck room - and of course, took it for the ride. Fucking in missionary position now, both using the full strength of their hips to drive his hard cock deep into her tight pussy, they also kissed hornily, biting each other's lips from time to time in a lewd display of passion. Passion the not-so-solid bed couldn't take and when their orgasm hit, the furniture collapsed under them, sending them on the floor. Luckily Ashley was a soldier gal, not some delicate princess, so she left unscathed even with James crushing her with his own weight.
Now however they needed to get back to the upper deck - and that meant stairs, and that meant another round of hot, passionate sex. This time Ashley was on top, once again riding James' cock like an Amazon - and then a lewd idea appeared in her mind. Grabbing the upper stair she squeezed his cock with her pussy - and then practically dragged him up by his dick, using all of her powerful leg muscles. One step at a time, she repeated that move until they were on the very top of the stairs when she continued her ride until another powerful orgasm hit them both and another batch of potent sperm filled her womb - with how much and how often James was cumming, Ashley wondered if her eyes already turned white.
Now they finally got to the engineering room... and Ashley kind of lost it. Being in the room Tali'Zorah - her former boyfriend's new girlfriend - worked daily, the dark mist clouded her mind. Yelling at Vega to fuck her harder and longer than Shepard, she dragged him from a console to a console and from a railing to a railing, taking his cock with wild abandon from upfront when she was perched on the console and from behind when she braced herself against the railing. At the same time, she didn't allow any of them to come - thus frequent changes of location - until they were fucking in the engine room. There, they experienced one of the greatest orgasms they ever had, also because of the humming of the engine resonating in their bodies, sending their genitals into pleasurable vibrations.
When the dark cloud left her mind, Ashley sat on the floor kind of depressed, but then James showed that he was more than a gargantuan cock, agile tongue, and superhuman stamina. Holding her in her arms he told her that everyone has a dark side, and her outburst meant that she still had some bottled-up emotions. And now, when she released them - in such a sexy way, he added - she could finally continue to live free of the past. That's very lovely of you, she answered, and then grabbed his cock and led him back to the elevator, her gaze alone promising even more sex for them. And her kisses this time weren't aggressive, but sweet and passionate.
To the hangar they went this time and ignoring all the consoles set there - Ashley had enough of them - they went straight to James' corner. There, they performed an amazing feat of strength together, when they both grabbed a pull-up bar and started to do pull-ups - but very soon his dick slipped into her pussy and they were straight-up fucking while exercising. They both teased each other to let the bar go while doing so, but they managed to keep themself in the air long enough for another orgasm.
With that, they had sex almost all over Normandy... but not in Kodiak. So in no time James lifted Ashley again, carried her to the drop shuttle, and slammed her against its side. Next, he proceed to fuck her against it, his thrust so powerful that it shook even such a heavy vehicle. After she cummed, she dragged him onto the front and rode him on the hood till his own peak, and then they finished with fucking inside of it, on both front seats and in the back, doing it doggy style with his hand taking a hold on her hair and both of their hips working to a common goal: filling her pussy with more of his thick seed.
Eventually, they lay on the floor of the shuttle, panting hard, covered in sweat. White ooze was leaking from Ashley's well-fucked, cum-filled pussy and even James' ever-ready cock shrank and softened, and was now resting against his tight.
"We have to go for our clothes," Ashley said calmly, as if they hadn't just finished an hours-long fuckfest. "We left them in Shepard's cabin."
"Let's go then," James answered and they helped each other to get on their feet. "Damn, Ash, you really drained me! My muscles, my cock... It couldn't get up even if I wanted to." After he spoke that, a weird gleam appeared in Williams' eyes. A gleam that got explained the moment they entered the elevator again.
"Challenge accepted," she said, kneeling and pushing the button which would get them from the lowest deck they were on (5th) to the most top which held the captain's cabin (1st). Before the door closed, she grabbed James' flaccid cock. When they were on level 4, she was furiously masturbating him, feeling how it was becoming harder and bigger under her assault. When they were on level 3, she put it in her mouth and licked all over it; James closed his eyes by then, leaning against the wall. When they were on level 2, she pushed his cockhead into her gullet and squeezed her throat muscles before bobbing her head fast. Finally, when they reached level 1 she felt Vega's cockhead expanding and before the door opened, he was cumming into her mouth, filling it with another big batch of semen - not as big as his previous ones, but still enough to put most of his fellow men to shame.
