Yes, with sex

Mark was shocked at the gravity of her request. No not request, an order. Like sex was the simplest thing in the universe, like they are supposed to just do it, without any morals, no attraction, just a means to get to an end. Well, there was some attraction, but never in his wildest dreams Mark would expect to be with someone like that.

"Just like that?"

"Just like that."

She confirmed, finally taking off her jump suit, her large breasts got released. She had a tattoo on her stomach, a spiral with some sort of unrecognisable letters.

"Are you a prude? Take off your clothes. Or is it some kind of primitive religious thing. Holy big-giant head, you are not in a celibate? Asking, cause fucking hand job might not be enough."

"No, no." Mark raised his hands and began to undress himself. "It's just... Unexpected. And forward. Usually it takes a bit more for human girls to, you know. Get that."

She approached him confidently, put an arm around him and then, closely, in his ear, whispered:

"I am no girl. I am Alearan woman." She switched to his other ear. "The number three hottest pieces of ass in the galaxy. And you..."

Kaliasi pulled back and looked at his naked form.

"Wow, you are... Muscular."

She admired. For Mark it was nothing special, just keeping himself in shape, he wasn't even as ripped as he was on Earth, probably because he spent a couple of weeks in space, most of which was with no artificial gravity.

But for her he clearly looked jacked, like a sculpture.

"You know, I had my doubts whether I should take you with me or not, but now I know that you will be very, very useful."

She approached again, wrapping her arms around him, and planted a deep kiss on his lips with hers. She tasted like strawberries, sweet, and he craved more. This lasted for couple of second until she stopped and placed a finger on his lips.

"Good, no allergic reaction."

"Wha-"

"The most dangerous part is behind us. A lot of species in the universe are not compatible."

She explained.

"Well, I'm glad we are."

She looked down, eyeing up his manhood, already stiff, ready to conquer the lands unknown.

"Oh yeah, we are very compatible."

Kaliasi pushed him gently on the bench bed. She hissed in pain, the shock cuff detected an ill intent in that action.

"Let's get rid of these things."

Mark agreed and lied down.

She stretched her leg to the other side of the bench, and sat on his thighs, taking his manhood in her hands. Only now he noticed that she had no nails, no claws or anything, just some pinkish markings at the end of the red hand.

Kaliasi moved up and down his cock, jerking it a few times. Mark moaned and there were even a few droplets of pre cum, already spilling out of his raging hard member.

Next, he semi expected her to go down on him, begin with a blow job, and make use of that interesting tongue of hers. He couldn't be more wrong, as she just fixed her position, and sat on his crotch, taking in his member into her pussy.

And that pussy felt fantastic, it was like several girls at the same time licking and sucking his cock, it was unlike anything he ever experienced during sex on earth. She was tight, but - as she lifted herself and then dropped again - also easy to slide in and out. There was also something extra inside that kept caressing his shaft, adding to overall experience.

She used her hands to lift herself again, and drop, and then over and over, continuously riding his cock. Mark extended his hands and put them on her breasts. His thumbs went to her nipples, playing with them. Her facial orgasmic facial expression told him that she like it.

"Fucking... More."

Kaliasi looked hungry, and wanted it, wanted him. Mark felt a sudden warmth on his right hand, the cuff began to expell a lot of heat. Clearly they were on the right track to removing there, so there was no stopping now. Not like he ever would want to stop that.

Switching his hands position, he pulled her in, sitting up, and while she was still riding him, they began to kiss and explore each others bodies with hands. She was soft in all the right places.

Her pace increased, she was grinding on him, and Mark noticed something weird going on with her skin colour, it was changing, becoming brighter, turning quite quickly from red to orange.

And that turned him on even more. When he was sure that she was steady, he grabbed her ass cheeks and then stood up with her, lifting the sexy alien up while still fucking, not even interrupting the rhythm.

"Give me... Yourself..."

Kaliasi whispered passionately as he felt he was close. They were both heavily panting, intent on just ignoring the pain coming from their cuffs, and focusing on just each other. The two lost souls, needing each other, somehow fate mixing them together and creating...

"Whoo, the cuffs security is broken!"

Kaliasi almost screamed into his ear, and she pulled back, from him, and landed gracefully on the ground.

Mark, with his bare, covered in unknown juices, extremely hard and ready to cum cock, stood there, like frozen statue, not sure what just happened.

"You alright there, Mark?"

She asked, her skin was already coming back to her previous colour.

"Umm... Yeah, why did you stop?"

"We achieved our goal. We are on a time limit." She answered.

"But... Fuck, I was almost there."

He shook his head, and still, with a hard on, he began to dress back up.

"I know. I'm saving some of that for later. And it's fun to see you like that, hahaha."

She laughed, and Mark felt like he was the one fucked over in this situation.
