Thane's blood was on fire. Shepard was pressed against him as he held her pinned against the wall of her quarters. Their mouths slanted against each other, almost as though they were each going to devour the other. He had one hand on her thigh, pulling her leg up and around his hip, as the other braced them both against the bulkhead. One of her hands was on the back of his head, holding his lips against her. Her other hand was busy trying to undo the closures on the front of his shirt. He groaned in equal parts frustration and arousal, and let her leg down in order to remove the clothing impeding them both. His hand slipped from the wall to tangle in her hair as he swiftly undid the buckles and zipper holding his jacket on, before turning his attention to her clothes.

"Ah, Thane," she murmured as he move his lips from her mouth to her throat. They broke apart as she removed her shirt and bra, and both paused for a moment to look the other over. Her skin was flushed, the gentle curve of her breasts moving with each breath, and her lips were swollen from his kisses.

"You're beautiful, Siha," he whispered reverently, and she reached her hand to trail her fingers lightly across his chest, and then they flung themselves back together, his hand only just reaching forward in time to prevent her head from crashing against the wall. Hands scrabbled over fastenings as they both attempted to remove what was left of their clothing without separating. He lifted his fingers to cup her breast, and her resulting groan caused his throat to rumble with a sound of arousal that he didn't think she could even hear. Her nipple was a tight little bud against his palm, and Shepard let out what almost sounded like a whimper as he pinched it lightly.

Breaking off the kiss, he turned his mouth to the other breast, laving the pale skin there with his tongue before scraping his teeth over her nipple, which elicited another sigh from the back of Shepard's throat. Her hands were also busy, scratching her nails down his back and sending jolts of anticipation through him. His cock was hard, throbbing, and he needed to touch her everywhere, to find the release that he knew only she could provide. He knew that he need only lift her leg over his hip again and he could sink into her warm wet heat, and the thought was making him crazy. He also knew that his Siha deserved better that a fast, heated coupling against a wall. It was a war between instinct and heart, but in the end his heart won out. With as much tenderness as he could muster, he pulled her away from the wall, intending to lift and carry her the few steps to the bed, but Shepard was no delicate flower, content to be passive in their lovemaking. He found himself being backed up towards the bed, their mouths back together as she trailed her fingers down the back of his neck and around to his throat frills. Another growl sounded from him, and he laced his fingers into her hair, hovering somewhere between trying to draw her closer and pushing away from the intensity of sensation. The back of his knee hit the bed, and they both fell back, he using his body to cushion her landing. The position they landed in had his erection pressed against her center, and he could feel the warm wetness, teasing him. Shepard could obviously feel it too, as she groaned and ground her hips against him, making him hiss with the tantalising feeling of being so close to her.

"God, Thane," she whispered against his lips, "If you don't fuck me I think I might die." He would have chuckled at her hyperbole had he not felt the same way. Her hips shifted against him again, causing his cock to twitch and making them both moan. It was exquisite torture. He could spend a lifetime teetering on this precipice with her, driving them both mad with wanting. They didn't have a lifetime, though, and the way that Shepard was shifting herself up and down against him was quickly making it impossible to think of anything besides driving himself up into her. He reached down between them and found the small nub that was the center of her pleasure and rocked his finger back and forth against it, wanting her ready for him, not wanting to hurt her.

"Ah, god, Thane," she cried out, her hips pushing back against him with every movement of his fingers. She scraped her nails along the frills on one side of his pelvis and he lost any semblance of control that he had been holding onto. It was too much. He could feel how wet she was against him, and he couldn't wait any longer. He just hoped to god that she was as ready for him as he was for her. He placed a hand on her hips, urging her to lift upwards, and she immediately understood what he was trying to do. Lifting herself up, she used one hand to continue teasing his frills while the other grabbed hold of his cock, guiding him slowly into her.

Thane's head tipped back as a rumble of pure pleasure was ripped from his throat. Shepard lowered her hips, impaling herself on him, and mirrored his action, throwing her head back and moaning. She was so hot and wet and tight, he had to hold himself back to keep from thrusting up into her. She rolled her hips, gripping him snugly, and he almost shuddered with the effort it took to keep still.

"Please, Siha," he entreated, "Am I hurting you? I don't- I can't-" he was cut off as she lifted herself up off him slowly, and then pushed herself back down.

"For the love of god, Thane," she said, "If you have any mercy at all you'll stop talking and fuck me!" It was all the invitation he needed. With a growl that sounded animalistic even to his own ears, he pushed himself upwards, rolling at the same time so that Shepard was beneath him. He thrust his hips forward and they both cried out. He withdrew slowly, drawing out the remarkable sensation as her inner muscles gripped him, trying to pull him closer as he moved back. He began to move with a rhythm, slowly at first. Shepard wrapped her legs around him, her nails digging into his back as her neck arched. Each time he thrust she let out a soft groan or whimper, each sound urging him on.

"Faster," she whispered, and he was only too happy to oblige. He moved his hips faster, then reached his hand down between them and found her clitoris again. Her breath hissed out as he pressed his fingers against her, and he knew that he would have markings on his back when they were done. He wanted them; he wanted her to mark him. He leaned forward and nipped gently at her neck, dragging another moan from her. His hips moved faster, light dancing behind his eyes as his pleasure increased. Shepard was meeting him with each thrust, grinding herself into his fingers and squeezing his cock. He wasn't going to last much longer, but there was no way that he would let himself come before his Siha had found her own pleasure.

Gritting his teeth to maintain control, he tilted Shepard's hips forward so that each thrust brought him in contact with her clit. He held her waist with one hand, and balanced his weight on the other, and he could hear when her breathing started to hitch, coming faster and more desperately.

"Oh god, Thane," she keened, "I'm so close. Don't stop don't-ah!" She broke with a cry, her walls spasm around him as he continued to pump into her, keeping pressure against her centre to prolong her pleasure. Just as her cries faded he found his own release. He stilled, calling out her name as his seed shot from him, holding himself to her as he came back down. He kept his eyes closed, wanting to hold onto the moment for as long as possible. Shepard brushed her hand down the side of his face, then leaned forwards and kissed him gently.

"Siha…" he breathed, contentment spreading through his body. He withdrew from her slowly, causing them both to groan.

"Careful, Thane," she said, humor evident in her voice, "We don't have time for round two."

"There are forty-five minutes remaining before we hit the Omega-4 relay, commander," EDI's voice rang through the cabin. Shepard and Thane stilled instantly and exchanged a shocked look, before the commander addressed the AI,

"You better not have been listening to that, EDI, or I swear…"

"Of course not commander," the voice answered, and both Thane and Shepard relaxed for a moment before she continued, "I was watching." Thane knew that his horrified look must have been similar to the one on Shepard's face. He was about to suggest that they dismantle the AI core piece by piece, when EDI said, "That was a joke."

"Fuck off, EDI," Shepard said, laughing.

"Logging you out," came the answer, and they were alone again.

Thane almost started to speak, wanting to say something, explain his earlier behaviour maybe, but the tired look on Shepard's face made him change his mind. Silently, he shifted over on the bed, and pulled her to him so that her back pressed against his front. She sighed softly, and nestled her head against him. He held her until Joker called to give them a fifteen minute heads up. It was time to go.

"Siha, I-" she shushed him as she had before, her finger against his lips,

"I know Thane," she said, "I know." She leaned in and kissed him tenderly, and then the moment was over. They both rolled off of the bed and put their clothes back on. They had a suicide mission to complete.
