"I want to get taken out by a Gutter," said Dan.
"That's against orders," Christofer objected, but he felt his prong begin to stiffen in his uniform trousers. "They've already taped a couple of studs being taken out that way, so count me out."
"It sure beats some things I can think of," said Dan. "Checking to see if Giles's latest find is poisonous isn't my idea of a fun way to go. So . . ." He tossed aside the last of his clothing and stood, stark naked in the sunlight that filtered down through the fern-trees. "Besides, I got an idea."
"Yeah? The last time you had an idea --"
"That wasn't my fault; how was I to know we were betting our balls on that game? I still say it was worth the risk, just counting the fun we had, even though we barely broke even."
"Yeah, yeah. So, what do we do now?"
"First, we strip," said Dan. "Then we get nice and hard. Here's a pill." He gulped down one pill, handed another to Christofer. "And after that . . . ah, here comes one now."
Christofer saw a donkey-sized, long-snouted animal stroll towards them. "But . . ."
"Come on -- strip -- that's it. Now, lie down on your back -- yeah. Now I grease up your prong -- you got a nice, long one, y' know, and I know you've been hot to ram it up my ass ever since we met -- right, stud? Well, now . . ."
Christofer obediently stretched out on the mossy ground- cover. A couple of twigs dug into his back; he sat up, brushed them aside, stretched out again. He looked up; Dan straddled Christofer's narrow hips, facing Christofer's head, and knelt, carefully impaling himself on Christofer's rigid shaft.
"Tight fit?" asked Dan.
"Yeah," said Christofer. "Take it slow, or I'll shoot before I'm all the way in. Like you said, I've been hot for your butt ever since -- you know."
"Now -- the real fun," Dan said, as the Gutter ambled toward the two naked Space Marines. "The Gutter takes me off while you spike my ass for a two-way fuck-and-suck."
"Yeah?" Christofer asked as he began to thrust his long, hard prong up into Dan's butt. "You could do the same thing sandwiched between my prong and a good cocksucker."
"Well, for one thing, there aren't any good cocksuckers in the Space Marines. And for another, Gutters beat any other kind of sex from here to Arcturus and half-way back."
"Yeah? It's gonna be kinda hard to explain how come I let you get taken out by a Gutter while I'm fucking your ass -- even though you got a nice tight one."
"Okay -- okay; how 'bout I toss in my balls too -- when the critter cuts 'em off, you can have 'em."
Christofer reached down, weighed Dan's big, warm testicles in his hands. "Okay, okay, we got a deal." As Christofer thrust and thrust again up into the tight passage that gripped his shaft, he watched the Gutter stop alongside himself and Dan, watched the carnivore's trunk-like snout settle onto Dan's upright shaft and begin tightening and relaxing, tightening and relaxing on Dan's glans.
Within a dozen strokes, Dan's muscles snapped into etched relief as he reached climax and pumped his load into the feeding tube that was eating him alive. And as Dan climaxed, Christofer rammed himself to the hilt in Dan's spasming ass and shot his own load.
The two naked Marines panted for a few moments while the Gutter kept feeding on Dan's shaft and Christofer kept thrusting himself up into Dan's muscular body. Then, gradually, pressure built up again in the roots of Christofer's prong, released at last in another jet of hot ball-cream just seconds after Dan's second climax.
"How's it feel?" asked Christofer, when the pair had caught their breaths again. "Is it really worth it, being castrated like this?"
"With this thing grinding away on my cock and your prong hammering up into my ass -- is this ever worth it!" Dan reached behind his butt, groped Christofer's balls. "You're a real well- hung stud yourself."
By the time the Gutter's trunk reached Dan's balls and severed them, both Marines had lost track of how often they had shot their loads. Christofer devoured Dan's balls, bag and all, savoring the taste of fresh, raw meat. Dan climaxed again while the Gutter was eating his prostate glans. The pair chatted quietly for a few minutes with Dan still sitting astride Christofer's hips, impaled on Christofer's cock, and Christofer still lying on his back, but now with his head and shoulders propped up on his arms for a better view of his naked fellow Marine.
Dan was describing how it felt, being gutted, when suddenly Christofer realized that something was exploring his own prong inside Dan and -- a moment later -- had seized it. Christofer stiffened, tried to pull back, then relaxed as he realized the Gutter's snout was beginning to rasp away his own glans.
Dan asked, "What's the matter?"
"Instead of gutting you, the critter's eating me."
"Want me to --"
"Might as well stay put -- it won't let go easy, once it's started feeding, and I'd rather be castrated all the way than come back with a half-eaten prong." Christofer squirmed, relaxed, then thrust up into Dan again. "I think I've got at least one shot of cream left, maybe two. And after that --"
"Your balls." Dan was silent for a moment. "Like I said, you're a real well-hung stud." He licked his lips. "If . . ."
"Are you hinting that, just maybe --"
"Well, yes."
"After getting me into this fix? No way."
"Not even -- just a nibble?"
Dan put on his most plaintive expression. Christofer scowled, then said, "Just a nibble -- okay, half a ball, then. And I think I'm coming to a boil again." For a few moments, Dan rode Christofer while inside Dan's body, the Gutter's snout fed on Christofer's prong, rasping away at the juicy shaft until the friction coaxed out another jet of hot cream -- a few moments later, still another -- and a final spurt as the Gutter carved Christofer's balls from the base of his shaft.
Dan retrieved Christofer's balls, bit off half of one, and wordlessly passed the rest to Christofer, who ate them as the Gutter reached his prostate and wrung out a final but spermless climax.
"Now what?" asked Christofer as the Gutter slowly withdrew its snout from their naked bodies.
"Let's head back to base."
"Report to the Lieutenant, or . . ."
"Check in at the mess tent," said Dan, getting a bit stiffly to his feet. "We can invite the cook and the guys on KP and anybody else who drops in to take turns, fucking us before we get cut up into steaks and chops for dinner."
