it's now or never.

You were still a virgin, stranded on an hostile world were pretty much anything could kill you at any moment and to be honest the only surviving member of your crew didn't like you much, saying nothing to how little she respected your authority.

Maybe it was shock, grief, a stroke, or something she ate or breathed, but she just sucked your dick and was begging you to fuck her.

With a life expectancy counted in hours or minutes it wasn't hard to solve this equation, skipping this chance (probably your last one, either you or the last woman available could die at any time. ) to check a vague feeling of weirdness wasn't a good plan.

One girl once told you that she wouldn't have sex with you if you were the last man on the planet, you were now in this situation and were going to test it for yourself.

You removed the heavy toolbelt to get more comfortable and knelt near her naked body. You removed her belt to toss it with yours and her clothes on a pile of moss near you. You can barely contain your excitement, unlike the last time, this time laying naked with Diana would end up in sex.

"Come on Captain my hangar bay is open, dock your ship!" She taunted you.

You had trouble finding anything to reply. Any comment or compliment you tried in your life failed to impress girls, you wouldn’t want to say something that would get her out of her stupor and reject you, not so close to it.

How hard could it be? You had never done it but saw it countless times and humans with no training in it seemed to have managed it just fine for millions of years.

Resting on your hands you laid over her, trying to aim the tip of your dick at her open and welcoming pussy. You had a moment of hesitation as you were unsure how exactly to insert yourself without falling on her. But she was taking a very proactive role in this. She took your dick into her hand and stroked it gently to get it harder, toying with your foreskin.

You were still wet from the blowjob and her pussy was flooding. When she inserted your member into her slit it went right in. She was not very tight (or you were not that big, maybe both) so the feeling, while incredible was teasing more than stimulating.

As she saw that you had some trouble with your posture and getting a nice rhythm to your strokes she closed her legs around you. In a move that showed it had been practiced many times, she rolled you onto your back in the moss finishing on top of you without having your dick exit her hole.

"That's better, don't worry we will manage to get this canon to shoot its load." She told you.

She was now bouncing on you, impaling her pussy on your hard cock, trying like her life depended on it to make herself cum using it. Your hands now free and were facing a pair of giggling boobs, even you could figure this one out, your lack of skill with girls had its limits.

You grabbed gently the mounds of flesh, rubbing her erect nipples with your fingers and watched her squirm and moan as loudly as yours. You must be doing something right because Smith looked very pleased by it and her frantic moves increase on your cock.

There was something you had to try, it was to you more intimate than sex and you didn't knew if her sex crazed frenzy would make her accept it. You dragged her down towards you and without hesitation kissed her on her lips.

She reacted to it by slipping her tongue inside your mouth and returning your kiss with passion. It was to you an accomplishment as it was something that you had being sometimes close to achieve but always failed to get.

You didn't knew if it was having just had your balls drained by the blowjob or that her pussy wasn't very tight but you were impressed at how long you were lasting in her without cumming.

Without years of filtering your senses through your neural implant (few people did it but it helped you to keep being focused on things without distractions.) you wouldn't be able to think at all with what your dick was experiencing.

Diana was starting to contract her pussy muscles in a massage of sort, trying to milk you inside her.

You ability not to lose all sense of reality under the continuous stimulation was crumbling when you notice on your implant's chronometer that it had been one hour since you started fucking her. (It was your first time and you started it to see how long it would last.)

That was wrong, it had to be wrong!

Even with empty balls you would have had a dry orgasm after that long. Hell after an hour you should have been able to cum again anyway. As good as she could be sucking dick you had very often been able to cum in few minutes after an orgasm in some of your wanking sessions before.

The chronometer didn't seem to be broken but it didn't make any sense. From what you've seen or read about lasting that long was nearly impossible, only imaginable during weird tantric sex that was paced to make the man last while keeping him hard. This was not what you both were doing. She was going at it as hard as she could and you felt your pelvis strut forward on each of her moves.

Now that you thought about it she didn't cum either, despite her small moans of pleasure and having started to play with her clitoris for nearly twenty minutes she hadn't yet succumbed to ecstasy.

You hadn't eaten anything today and hadn’t drank for hours but were not bothered by hunger or thirst. You were unwilling (unable maybe?) to stop, the pleasure of the unending sex too strong to do anything that would jeopardize your release.

Diana had started this by taunting you, but she hadn't spoken for more than one hour (you were closing on the two hour mark now) and when you tried to talk to her you found yourself unable to do so.

A piece of the large mushroom above your heads fell down on the ground, it passed the rain of glowing spores that were showering you and landed on one of those by lumps of moss around you in the large clearing around its foot.(you counted more than 200 of them)

The mound of moss that you were bouncing on, that now looked more like some overgrown mold, finally ripped open under the repeated pounding.

Under it were two skeletons, humanoids, larger than humans and each having two pair of arms.

What was now creeping you out was that they were in the same position that Diana and you were right now. Your mind immediately understood what must be happening.

Those creatures like hundreds more, stumbled here, went under this mushroom and fucked themselves to **** before fertilizing the ground with their bodies. This area only had fungi and mushrooms, even the trees were dead ones covered in small fungal formations in sex organs shapes. No animal of any kind, even the large predator chasing you turned back when you entered it.

You were now dreadfully aware of the fate awaiting you but neither you nor Diana were able to do anything about it.

You were going to continue fucking, until there was not a bit of energy in your bodies. Fucking in search of a last orgasm (the first while having sex in your case ), one that would never come.

You so long wanted to find a girl to have sex and stay with...
