Thane visits Shepard the night before they go through the Omega-4 relay and they turn their spark of connection into a roaring flame. He's ashamed at how much he wants her but she turns it into something wonderful...
Amplexis (or Amplexus) is a frog thing where the mating pair is locked together for a certain amount of time after coupling. Since the Drell are Frog-like I tweaked it to work for them ;) I WAS SO EXCITED TO REVISIT SHEP AND THANE'S FIRST TIME ONLY WITH ALL MY NEW TALENT FOR THE SPECTRE SEDUCTIONS GIFT EXCHANGE for @bebravedearheart
Also on AO3
“Siha, I—I have known I will die for many years. I’ve tried to leave the galaxy better than I found it. You’ve helped me achieve more than I thought possible. We’ve righted many wrongs…I’ve spoken to my son. I should be at peace on the eve of battle. But…I’m ashamed. I’ve worked so hard. Meditated and prayed and done good deeds. Atoned for the evils I’ve done. Prepared. But now, I consider my body’s death and a chill settles in my gut. I am afraid, and it shames me.”
She crossed the room, her presence a comfort as she stood beside him, closing her hand over his fist and bringing it to her lips to press gentle kisses to his abused knuckles. “Thane…be alive with me tonight.”
He’d accepted that he was going to die and had made his peace, but now he had to deal with the guilt that he had been given something he wanted to live again for: her. She’d come barreling into his life and he’d felt a spark of instant connection, and now he didn’t want to leave this life behind, didn’t want to leave her alone and without him. Thane’s hand cupped the back of her neck as their lips met in a passionate kiss; every thought he had, as of late, was of her and he wanted her—wanted this: them together as one, his desire for her overpowering any other rational thought. He was going to die; if they survived going through the Omega-4 Relay then his Kepral’s would finish what it had started so many years ago. But, as he wrapped a lock of her hair around his fused fingers and tugged her head back to trail kisses down the column of her neck making her moan and arch towards him, pressing their bodies together, he suddenly didn’t want to think about his disease or their suicide run, instead he wanted to lose himself in her; the way she smelled, the way she tasted, way she felt as she moved against him and the little sounds she made whenever he touched her.
He claimed her lips with his own again, inhaling her exhale as her hands frantically ripped the belts on his jacket out of the buckles so she could pull the zipper down, Thane groaning into her mouth when her hands touched bare skin, soft fingers sliding over the exposed microscales of his stomach and chest as she pushed the jacket off his shoulders. He let himself get lost in her caress, having forgotten how good it felt to touch and be touched before he gripped the hem of her shirt with both hands, yanking the fabric of her tank top upwards and ending the kiss reluctantly as she stretched her arms up so he could pull it off of her, his lips crashing back against hers as the garment cleared her head. She nibbled at his bottom lip, before bracing her hands against his pecs and pushing him a step back, teasing fingers dipping under his waistband, Shepard pushing his pants off his hips before moving to her own body, shimmying out of her shorts, the fabric pooling around her ankles before she stepped out of it, standing naked before him and letting him drink her in.
There was the sensation of motion as he backed her towards the bed, the mattress bumping into the back of her knees, the kiss breaking as she fell into the center, her eyes roaming over him, as she parted her legs in invitation, baring her most intimate part of herself to his gaze, his cock hardening at the sight and black eyes blazing with affection. The edge of the mattress dipped under his weight as he crawled up after her and settled himself between her thighs, his hands roaming across her bare skin, mapping her body with his touch. She was absolutely breathtaking. Shepard draped one leg around his hips, pulling him closer, the two of them moaning in unison as his hardened dick rubbed against her core. He’d been thinking about this for far too long and had wanted to get this right, so he’d gone to both Dr. Chakwas and Mordin for advice and they’d given him several things to read on human pleasure as he had no sexual experiences with other races to draw on—but he was a fast learner, and the sounds she was making told him he was on the right path. Thane caught her hand in his as she reached for him, pressing a kiss to the inside of her wrist, her palm and her fingertips, the gentleness with which he was handling her nearly undid her right then and there.
Her head fell back on a moan, chest heaving as he rubbed his cock through her folds coating himself in her arousal. She rolled her hips, creating a delicious friction between them and making Thane groan before slowly entering her, letting her feel every inch of him as he filled her to the hilt, her walls stretching and shifting around him. Shepard canted her hips, taking him deeper inside her and whispering his name almost reverently as he reached between them and pressed the pad of his finger to her clit. The scales around his eyes crinkled slightly as he smiled down at her; every inch of her skin flushed as she watched him, before she cupped the back of his neck, bringing his lips down to meet hers again. She rocked her hips back and forth, impaling herself on his cock, the coil inside her winding higher each time he pressed her clit with his finger. Her walls clenched around his shaft as he pulled back, only the first inch of his erection still inside her, before he snapped his hips forward, the two of them rocking together and seeking their release.
He surged forward, her insides stretching to accommodate him as he rocked his erection against the roll of her hips. Her breasts brushed his chest, nails scraping lightly down his back as they sought his rear, soft hands cupping his ass and pulling him deeper within her, his hands ghosting over her breasts and pinching her nipple, the bite of pain amidst her pleasure had her gasping. She eased her hips backwards then arched up again taking him deeper, Thane pressing into her again as he gripped her hips and thrust slower and deeper. His lips closed over her pulse point, her heartbeat fluttering under the stroke of his tongue as he tasted her skin, sucking hard before pulling back and smiling as a dark red circle bloomed on her neck. She was his and now she had the mark to prove it. He used her hips to guide the speed of his thrusts, her back arching and insides clamping down around his cock as she bucked her hips against him.
Need hit him like a tidal wave as he thrust forward again the tension inside him climbing higher, a shiver racking his body; he wasn’t going to last much longer.
“Thane…” She breathed as his fingers trailed back down her body to circle her clit, a whimper of pleasure escaping past her lips as he touched her with just the right amount of pressure and at a pace that had her seeing the same stars behind her eyelids that she did whenever they kissed.
“Let go for me, Siha.” He rasped, sucking at her pulse point.
He felt her muscles contract beneath him as he rocked his hips once more, the friction sending her over the edge of ecstasy, her orgasm racking her body with tremors, but as she climaxed around him, he felt it; the ring of glands of the base of his crown activated, swelling ever so slightly and secreting a special fluid that locked them together and forced his own orgasm, his release spilling inside her. He felt the horror settling in that he'd neglected to mention the amplexis before they started this, but in his defense, it had been so long and he'd only ever been with Drell, who all knew about it and expected it, that he’d completely forgotten.
“So that’s what that feels like. I’d wondered.”
She was taking this rather well and Thane glanced at her in surprise, his heart fluttering in his chest as she smiled up at him—he wasn’t the only one who had done some reading it seemed; she’d wanted this as much as he had, he realized as she caressed his thigh with her toes. His cock twitched inside her as he held her hips, guiding them onto their sides, face to face on the bed, one of her legs draped over his hip; might as well get comfortable, as they were going to be joined for the next hour or two. He didn’t know how different a Human-Drell coupling was to two Drell, so the timing was a mystery, but something in him was excited to find out…which only made everything worse, but he couldn’t bring himself to stop this, not when he’d been so lucky as to find her. His Siha.
“None of this is fair to you, Siha. Loving a dying man.” He whispered, a slight warble in his voice betraying him.
She shrugged one shoulder before cupping his cheek with her hand. “The heart wants what the heart wants…and besides, nobody’s promised tomorrow, especially not me. I’m a soldier. One of the best, and I never know if a mission is going to be my last. Alchera was. And then I got a second chance and I met you, so now I just take it one day at a time—I’m not going to walk away just because the future’s uncertain. Most people only get one life, and I want to spend every moment I can of it, with you.”
He gazed at her, a smile dancing about his lips before he brought her mouth to his, her thumb grazing the red fringe on his cheeks, as she wiggled her hips experimentally, the amplexis still affording her some movement. She rolled them over so she was straddling him and bent to claim his lips, his tongue tangling with hers before she pulled back, smirking. She pushed up on her knees before sinking back down onto Thane’s cock with a moan, his head falling back onto the pillows, black eyes screwed shut in pleasure, both of them enjoying the slow drag of their hips where they were still connected
