James grunted as his hand moved faster, pumping himself harder as the water thundered down on top of him. He had chosen now to shower, knowing that the rest of the crew were busy with their duties, meaning that, not only would the water pressure be better, but that he wouldn't get disturbed.

EDI had observed this ritual from Lieutenant Vega on a number of occasions. It seemed preferable here than his bunk. She had wondered why at first but a pattern had emerged quickly and that one was isolation. In the shower room, he could be alone and sort himself out. EDI always detected a hint of shame from him when he finished himself off and she wondered why he felt ashamed. After all, this was a perfectly natural thing.

As a synthetic being, EDI had wondered if she could actual feel physical pleasure. She had explored her physical platform thoroughly, checking that it was functional. It had heat and pressure receptors in its surface, a function added to help with the infiltration part of the platform's design. But she had not really explored their usage. Also, there were areas of the platform that lacked such receptors, or at least the density that could be found in the human body...even though its epidermis was constructed to be a replica of it. It was an intriguing comparison.

From her findings on the extranet, there were many who would probably have found the picture of Lieutenant Vega, naked, dripping wet and masturbating furiously to be highly arousing. And she wondered if she should too. After all, the Lieutenant conformed to a number of parameters that were deemed desirable in a human male's body. However, what EDI had also discovered was that there was no standard for what humans found attractive or desirable. This caused further questions and observations.

Did she find him physically attractive? He was very different from Jeff, not just because he didn't suffer from Vrolik syndrome, but in terms of his skeletal structure and genetic make-up. Lieutenant Vega seemed to have been bred to be big whereas Jeff was slighter. But no, she decided that she wasn't physically attracted to him. Her own parameters didn't necessitate a huge, hulking mate.

Lieutenant James Vega could easily be described as a beast of a man. He was huge and easily dwarfed most of the male crew members aboard. He was well built, sturdy and heavily muscled. His frame had instantly drawn the eye of Reporter Allers when she had seen him. In fact, she had flushed immediately when he entered her eyeline, her reaction instant and chartable for EDI to use as a basis for future observations. And yet, Commander Shepard did not reacted in the same way at all.

His face wasn't classically attractive either, complete with a number of scars across his visage. However, although Specialist Traynor had no interest in men, she had commented on them a number of times, saying they made him look dangerous. He'd puffed out his chest at this, much like Wrex had done when he had strutted for Eve. She had also said that he had kind eyes and a sweet face, when he wasn't being moody. But Liara had wrinkled her nose at his posturing as he told Traynor about how he'd fought off a horde of crazed Collectors to gain those scars but made no comment.

A moan cut the air as James continued to fist himself, his hips starting to buck into the close confines of his hand, the other reaching down to fondle himself further.

In all the times EDI had watch him 'jerk off', as Jeff was so fond of saying, she had noticed that he did so in silence, with only bitten back groans and moans coming from him while he was busy. As if all his focus was on what he was doing, as he always stared down through the whole process, rather than on vocalising the sensations he was feeling. Maybe this also was part of his liking for isolation. EDI wasn't sure.

She had watched many of the crew pleasure themselves in various ways and each reacted differently to the process, although all did so in a muted way, a by-product of a life lived in the pockets of others aboard a ship. James was always quiet and focused. Jeff talked while he stroked himself, almost absentmindedly...both the talking and his movements. He said dirty things to himself about others. Sometimes it was specific, but most of the time it was general but it all depended on what was going on or what he'd been watching at the time. By contrast, Flight Lieutenant Cortez took a much more varied approach...sometimes wild, sometimes measured. His eyes always closed while he worked himself to his climax and sometimes he muttered a name. Always the same name. Always 'Robert'...what changed was the timber and tone of his moan. Sometimes it was soft and sweet, other times sharp edged, sometimes needy but always with a hint of sadness. She knew that it was his late husband that he spoke of when he came and it made EDI a little sad when he did.

'Fuck!' James blurted out and sagged, one hand shooting out to rest on the wall to stop himself falling over.

This surprised EDI; James never spoke, even when he reached his orgasm. He just ejaculated, sorted himself out, cleaned up and carried on as if nothing had happened. She wondered what had changed to make his so agitated, despite the properties of his recent act supposedly reducing such agitation.

She watched as James placed his head on the brushed steel wall and caught his breath, the water still gushing down him and washing away the evidence. He panted and EDI watched as his heart slowed and his external temperature started to decrease, but with each passing moment the tension in the room seemed to build and EDI would've bitten her lip has she a lip to bite right now.

'Jesus Christ Lola, what the hell are you doing to me?' he asked no one in particular before he finished his shower and left.

EDI was speechless for a moment, replaying all of recent the encounters between the Lieutenant and the Commander, looking for instances where the Commander had done something to him. She focused on the 'dancing' that they had done before he had gone to the shower. The two had sparred after Tuchanka; James had instigated it when he had seen that Shepard appeared down by the death of Mordin. He had said he thought it would cheer her up. They had sparred for some time, harder than when they had 'danced' on the way to Palaven. Blood had been drawn on both sides this time, but Shepard had still won.

Did James Vega like a woman that could beat him? It seemed that he did, for Shepard had won and he had had to go into the shower and masturbate and blamed her for it. Perhaps Jeff would like it if she dominated him? It wouldn't be difficult for her to dominate him. In fact he had a fair few vids of woman whipping, spanking and physically abusing and chastising men. She would have to research this but suspected it wouldn't be appropriate. Even minor force would hurt Jeff, really hurt him.

More investigation was clearly needed.
