Finally the four weeks that Mrs Samantha Kane, the human female from Terra Prime had to spend with Prof Gronxok, the Pishaach male from Ultor Prime, to 'help' him through his period of heat, were over.
Gronxok was now out of danger and no longer needed to mate. After one more week, he would become incapable of mating at all, that is until the commencement of his next heat after two Earth years (or one Galactic Standard year)
There was almost perfect silence in Gronxok's cabin. The only sounds that could be heard were, "Mmmm...hmmmm...slurrrrp...gllop...glok...slurpp...hhhmmm...pcchhhh....mmm.... hhaaa...hnu huu...glob...glug... gluggg...mmhh...hmmm...!"
Samantha was lying on top of Gronxok, stark naked; they were both naked. Her pink pussy was on his mouth and she was holding both his dicks in her hands, licking and sucking them, alternately as he diddled her clit with his fingers and ran his tongue over her labia.
Samantha suddenly stopped sucking him off and rested her head on his pelvis, crying out, "AAAAHHHHH?!"
Gronxok had inserted one finger into her cute butthole while continuing to play with her clit with his other hand and licking her pussy.
Then as he thrust his tongue inside her, moving it around, searching for her g-spot, she gasped and held her breath with her sweet mouth open, frowning and shutting her eyes tight.
Then as he held one of her round buttocks in his hand, one finger still inside her anus and diddled her clit with the other hand while continuing to probe inside her velvety pussy with his tongue, she whimpered, "Aaa...hhunnh..ahh..auuhh..huunhh...!"
When his tongue hit her g-spot, she cried out, "AAAAHHHHH!... OOOOHHH... I'M CUMMMINNNG... I CUMMING CUMMINGG... OOOOHH GRONXOOKKK....OOOOUUU...HA AH..AHHH..AH..AHH...OUUHHH...YESS...YES...YESS!" as she squeezed his cocks in her hands.
Her enticing round white ass jiggled sexily as Gronxok continued to finger her and tongue her and she kept moaning and cumming on his mouth....
-----
This was Samantha's fifth week with Gronxok and she didn't really need to be with him now. But the formerly devoted and faithful wife now found it difficult to let go of the ugly goblin-like alien with two dicks.
She had requested Dr Denfe to keep the entire deck under quarantine for one more week as she 'sorted out her feelings' and 'got it out of her system'. She hadn't listened to the doctor when she advised Samantha that the best way to get it out of her system was to stay away from Gronxok and start the therapy that she had prescribed for her.
Dr Denfe was of the opinion that Samantha's hormones had gone into an overdrive because of all the aphrodisiacs and meds she had had to take in order to be able to endure the almost continuous fucking of the last four weeks. The meds would take a few days to clear out of her system.
But controlled by her hormones and her emotions, Samantha had insisted that she was fine and gone back to Gronxok's cabin.
Dr Denfe noted that the beautiful human ambassador would probably also require some psychological therapy when this week would be over.

It was the last night of the fifth week of Samantha's mating with Gronxok.
She had spent this last week, fighting her feelings of guilt, giving in to her desires and finally, slowly coming back to reality when she noticed that Gronxok's libido was decreasing as his heat was coming to an end. Even her dancing for him, getting him to spank her or to electrocute her nipples, running a holographic simulation or speaking to her her husband in front of him, didn't do much to arouse Gronxok.
He would still occasionally get hard though. Then Samantha was guaranteed at least a couple of hours of sex.
That night, she was slowly riding the Pishaach, facing him, his cocks once again inside her ass and pussy, his gray alien hands on her full, lovely breasts.
She was moaning softly as she moved her round hips back and forth, up and down.
He had already taken her from behind once and then face fucked and titty-fucked her.
Now, as she squeezed his two dicks with her pussy and ass muscles, he pinched her pink nipples and kneaded her big breasts.
Then taking one of his hands off her breast, he spanked her, making her yelp, "OW!"
But she understood what he wanted and sped up the movements of her hips, moaning and gasping as she fucked him.
After a couple of minutes of this, Gronxok suddenly sat up, holding her sexy back to prevent her falling onto the bed. He then held her by her ass and embracing her tightly, stood up on the bed as she clung to him tightly, wrapping her long shapely legs around his waist.
She cried out as the alien began to fuck her hard, standing up holding her in his arms by her ass.
She came over and over again as he slammed into her, holding her like a rag doll.
Then, he dropped to his knees, still holding her, still inside her and pushing her onto the bed, lay on top of her as he continued thrusting into her, this time filling her up with his seed.
The next morning after they had both freshened up, Samantha started giving him another blowjob. But it had no effect on him.
He said to her, "It's done, dear Samantha. My heat is over. I won't be aroused until the next heat."
Samantha felt tears well up in her eyes, "Over? Just like that?"
He replied with a kind smile, "Yes my dear. It's over. I'll never be able to thank you enough for saving my life... Now that I can think rationally, I can't imagine how difficult this must have been for you. So I really appreciate what you've done for me."
"Can't thank me enough?" Samantha said, now flying into a rage, "I'll tell you how you can thank me! Get those cocks hard again and fuck me!"
"Samantha, you know I can't...."
"I BETRAYED MY HUSBAND FOR YOU... DISRESPECTED HIM.... I DESERVE BETTER THAN THIS... YOU BASTARD... YOU SELFISH BASTARD!"
"Prof Gronxok to Dr Denfe." the terrified Pishaach called to the doctor over the communicator.
