The goes on.

The huge load covered Sue´s face so her nose was closed by the sticky slime and she must open her mouth to breath. So a lot of Johnny´ semen poured into her mouth and Sue had **** but to swallow it. It made her cough.
When the three men saw this they began to laugh. Sue tried to spit the semen out but suddenly Johnny grabbed painfully her chin.
“Oh no, Sis! You don´t do that. This is a gift from your beloved brother. You´ll not spit it out, you´ll swallow it all. Hear me bitch? You will swallow it! Here, drink more!”
Johnny had sled forward and kneeled now over Sue´s chest. With a malicious grin he guided the head of his cock between her soft lips. More cum was spurting of his dick into her throat and Sue was **** to swallow it.
“Good so, Johnny. Make her drink a lot more. It is good for her! She soon will need lots of Protein!” Reed laughed when he stretched his neck to bring his head nearer to this scene.
Sure, in the human world she was his wife he had sworn to love and protect her, - but here and for the aliens that controlled him she was only a woman that should be fucked and humiliated.
And this he does. With the same scientific precision he had worked before. Nobody knew better how she hates to swallow cum. Or to get a dick into her ass. So his obsessed mind enjoys to lead his comrades to the best way to **** this wench in the most disgusting way she felt. And now it was his part too. Why should only the others have fun?
He had ever liked the taste of her love juices, dripping from her tight cunt. And he knew how he must handle her to make her cum.
With one of his flexible arms he spread her long legs and hold them apart. With the hand of the other he spread her pussy-lips and tingled her clit while he licked simultaneously her smooth inner flesh. Reed formed many little strings from his hand to fondle her sensitive flesh. Sue tried to struggle but with no success. He used his tongue variantly with swift soft or hard strokes, - then, suddenly he let her grow to the size of a penis and rammed it some times deep into her vagina. The stimulation had the effect he wanted, - her juices flew rich and he sucked them greedily from her cunt.
Johnny had spurted some more cum in Sue´s mouth before he grabbed her head by the hair and **** her to suck hard on his dick.
Sue felt dizzy, but to her own surprise she reluctantly obeyed his order. After some minutes whilst he **** his dick so deep into her throat, that she gagged she was “rewarded” with a new, huge load of cum which he gushed down her gullet. For her it felt like a hose stuck in her throat and a sticky, hot fluid was pumped through it into her stomach. Unable to resist she nearly fainted as load of load of his cum flushed down her throat when simultaneously Reed licked her nearly to an unwanted orgasm.
With half closed eyes she looked up into Johnnys diabolical grinning face with the evil burning red eyes.
“Hey, Sis. Was it good? Oh, your Lips are so soft and your throat is so tight. Do you enjoy your brothers cum? Was it enough? Tastes good, right? Should I give you another load?
What do you mean Sis, would Crystal like it when I fill her bowels, after I fucked the shit out of her little Ass?
Hm? Or would she found it inhuman? Ass-fucked and filled to the Limit with hot semen? I think I should find it out. - Later! When we are through with you, little whore-sister! ”
In this moment Sue´s body stiffed when suddenly Reed rammed a gigantic cock into her pussy.
“Hey, Stretcho! What about your Partners? I want fuck this little whore again. I think she needs it. But first of all, - I need it! “ the Thing growled.
“Me too!” Johnny sayed.
Reed rammed his cock some more times into Sue´s cunt, before he came with a loud grunt of pleasure. He smiled wickedly.
“Of course! She has enough holes to pleasure every one of us simultaneously. Which one would you prefer ?”
