Shepard and Thane lay in their bed on the Port Observation Deck for the first time as Arasiha and Mëhana. Her hair was a mess of flowers and strawberry blonde tresses. The sounds and smells of their passion filled the room.

He knew her body well. Knew where to touch and how to summon the most pleasure in her. He knew where to kiss her and where to lick or bite her. Knew when to dominate her and when to let her 'win'. He'd mastered the art of bringing her close to the edge only to deny her, then take her back with more intensity.

She knew Thane's alien form as well as she knew her own. She knew which folds were more sensitive to her tongue and which ones he liked to have nibbled. She knew when it was safe to pleasure him orally without threat of hallucinations. How to roll her hips to force moans from him.

She pumped her hips and he rolled his. She arched her back and stretched her body so he could see himself slid in and out of her. The sight heightening his desire, bringing him to fruition. He groaned his purring release when he arched into her. His fingers skillfully urged pleasure to the point of pain from the swollen nub of her clit. When he felt her inner walls spasm around his mast and was satisfied with the wetness on his body, the cries of ecstacy from her lips, he griped her thighs and slid out from under her. She fell back onto the bed. He did not give her time to recover or protest. His mouth was on the source of the moisture. His lips sucking on her plump red ones, enjoying the moans and cries she made in response. His tongue caressing and penetrating her sensitive areas, drinking the nectar that her body produced.

"Mëhana..." she moaned loudly, her fingers dug into the mattress. She felt him close his mouth and slide his lips over her delicate flower, humming. A renewed fire of passion bloomed in her loins.

"..mmm... Arasiha." he whispered.

"I.." she panted, ".. want you."

"mm-um." he hummed his denial.

"Please?" She whispered. "I need you, now!" She begged through waves of shuttering bliss.

Thane took her in his mouth aggressively with out answering her. She moaned and gasped for breath before awarding him the elixir he wanted. He drank her and lapped up all that remained before plunging himself into her, only the slippery wetness of his own lubrication between them.

He took her hard and slow, burying himself deep within her. She wrapped her legs around his hips, allowing him deeper penetration. He felt her tighten around him. Felt himself throbbing insider her. Felt the end of him surpassing the 'end' of her. Her cries mixed with his own urged him deeper. He lay over her, his muscles firmly pressing onto her body. One hand held her thigh, the other assisting his tongue with pleasuring her breast or cupping her face as they shared passionate kisses. There was one flaming blue aura around them . They were one.

The made love, strong and loud and wet. She soaked him with her love. He filled her with his. When they were too exhausted to continue they slept. When they were hungry they ate. The Normandy stayed on a steady corse for the Phoenix cluster. They never left the observation deck.

"Commander, we have arrived." EDI woke her with the announcement.

"Thank you, EDI." She groaned. She'd never been so sore or felt so good. Garrus was going to be furious with her for leaving him in charge for so long. She was careful not to wake Thane as she left the bed to look out the window. The Phoenix cluster in the Argos Rho nebula was surrounded by a lavender haze. On the surface of Intai'sei was an apartment Shepard had won, long ago in a game of sorts. She smiled to herself recalling the memory. It was going to be hot down there. She needed to pack light and lots of water. She grabbed a robe and slipped out of the room to go to her quarters and shower.

"Shepard, good to see you. I thought maybe you two died in there." Garrus stood in the hall, blocking the elevator. "I don't think that's proper duty attire, Commander." He eyed her robe, teasing her. His arms were crossed and he had a bit of a grin.

"Garrus, I'm sorry I've left you in charge for so long. I promise, after the honeym..."

"Don't worry about it. I've taken care of everything. Captain Vakarian has taken care of the Normandy in your absence." He interrupted her.

"Captain, hu?" Shepard crossed her own arms and leaned back on one leg. "Well, we'll see how that goes when we get back." She was grinning.

"I see, well, we wouldn't want to up set the crew with drastic changes in command." He was still tesing her when Thane appeared in the door way behind the Commander, clean and dressed in his leathers once more.

"I don't think that will be necessary." He was just as alert as ever.

Shepard shook her head. His stamina never ceased to impress her. He strode up casually beside her, hands clasped behind his back. A small blue flame here and there glinted over his scales.

"Right." Garrus nodded, eyeing the drell. It seemed the groom had woken up on the wrong side of the bed. "I'll be on the command deck, whenever you're ready to leave, Commander." He turned and left it at that.

"I'm going to shower and pack." Shepard said to Thane. "I'll be right back. You should pack a few things as well."

"Where are we going?" He asked, looking perplexed.

"It's a surprise." She grinned and took the elevator to her cabin.

Thane looked out the window of the observatory. The small planet below seemed to be unremarkable.

"EDI." He summoned.

"Yes, Thane."

"What can you tell me about this planet?" he asked.

"Intai'sei, the fifth planet of the Phoenix cluster in the Argos Rho nebula." EDI answered. "It has a twenty-seven point six hour day. An over all average temperature of forty-five pont fifty-six degrees Celsius with an arid climate. There are several human colonies scattered on it's desert surface. Intai..."

"Thank you, EDI. That is all I needed to know." Thane stopped her. A desert planet. One they could both breath on with out aid and did not need to wear enviro suits. Shepard was clever. He smiled to himself. He turned to the dressers to gather the few things he would need.
