It was wonderful. I had this beautiful black cock in my mouth while Josh's handsome face was around my white dick. His strong hands held onto my hips, while I held his. Gently we sucked in rhythm, wanting to prolong the enjoyment. No bedclothes to get in the way: the perfect 69, hanging weightless inside our spacecraft.
We were well practised, so usually manage to come pretty much together. We sucked and swallowed and massaged to get every drop out. Of course, we enjoyed it, but it was also standard operating protocol, blobs of spunk being unwelcome in zero-g. In our regular manoeuvre, we moved our hands round each other's body to rotate and kiss, while Natasha and Philly put the little garments on us which would catch any further dribbles.
The temperature is kept at a level so that we are totally comfortable naked, which removes the need for clothes and washing. We wipe each other down for hygiene.
It was a relief getting back into space after our time on Mars. We had hardly any sex as we worked on our mission. Lots to do and limited time till the launch window. Now we had little else but sex to occupy us for the next ten months.
Forget "carrying out experiments". Yes, we had some tasks to do, but most things were automatic and the journey was boring. We were fifteen light minutes away from home so there would be no practical phone calls or interactive games, just videos sent each way.
Later we watched the two girls pleasure each other orally. I never got tired of seeing the two of them: Natasha with her stubble of ginger hair and dusky Philly bringing each other to a beautiful orgasm. Sometimes they went 69, but mostly they liked to do it in turns, one hanging on to the other's legs while burying her face in the cunt, the other holding a grab handle to avoid drifting, and gripping her lovely companion with her legs when she came. Natasha flushed a beautiful pink and groaned, while Philly was unrestrained in her cries. There were no neighbours after all. In space, no-one can hear you come!
Unlike us poor men, they usually gave each other two orgasms in a row. I think it was to tease us and show the sexual superiority which we were happy to acknowledge.
They were slim and not large breasted, but how beautifully those breasts looked and moved when free floating! Josh and I also looked forward to the time in a few months when their hair would be long enough to float around as well. We had trimmed and shaved on Mars so we were all smooth, but would get quite shaggy as the months progressed. We were all of modest size, weight being at a premium and height being a disadvantage. You had to be less than a certain height to join this particular ride! And it helped for spare parts if space-suits were interchangeable.
In space, oral sex rules. Fucking is possible but is more complicated, and we would have our share of that. I would fuck Josh and both of the girls, and he would fuck me and the girls. That was the rule. Fair shares. Perhaps not entirely fair. The girls were the only ones to be double penetrated, but I would sometimes enjoy being fucked and sucked.
Next day was a fucking day. We have a treadmill we all have to use every day to reduce the loss of muscle in zero-g. It has a harness and elastic straps to substitute for gravity and give us something to push against. It doubles as a bed for sex. Philly stood in front, harnessed elastically in place to a pad and I stood behind or lay on top, depending on how you viewed it. With the elastic in the right direction I would have to pull backwards similar to lifting the weight of my pelvis on Earth. This simulated lying down. I pumped and pumped joyfully against that beautiful round brown butt, supporting my virtual weight a little on my elbows, but not too much as she likes the rare feeling of weight on top of her. She never comes this way, but does not mind since both girls get far more orgasms than us guys, but enjoy a long fuck just the same.
It was a great ride, as it usually is, but the fun was not over. Natasha floated in to help Philly out and deal with my condom. She milked my cock a little to get any late sperms out, and carefully removed it in the correct space procedure, then added the absorbent cover which would take care of any later dribble. As the biologist in charge of our bioreactors, she would take the spunk to feed some tame fungus which would in due course give us our favourite pรขtรฉ. The thick condom would be cleaned and used again. Our pee and poo were also recycled biologically, or the missions would be impractical. We are more or less a closed environment, and almost nothing goes to waste.
Josh rearranged the pad and harness so that I was bent over, and directed the elastic so that we both seemed to be standing. With a precisely measured amount of lubricant, he then proceeded to fuck me. I quite like being fucked when I have already come, because I can appreciate the sensations, and because I like to feel the pleasure that Josh is getting from me. Yes, I love him. We all love each other, which is why our crew will survive the two years that the round trip to Mars takes. We were halfway through and on our way home! But for the moment I imagine I am standing at home, bent over the bed and being loved, while my two women watch. I pretty much know how long he will take, and am prepared for those stronger strokes when he comes. I also like to see his face when he fucks or is sucked off by one of the girls. Love does not come any greater than what the four of us share.
