The space freighter Serene Dawn had taken off for the planet Zeron 5, a journey that would take nearly one earth year to complete. Steve the skipper and Tony the navigator put the craft into warp drive, set the automatic control system and had started to relax. They took off their spacesuits and were just wearing tee shirts and little shorts.

There was, however, an essential difference between the two crew members, Steve was human and Tony was an android. Androids looked exactly like humans, had human emotions and needs, the only difference was that they couldn't reproduce. For this reason amongst others, many male androids who worked closely with male humans developed feelings for the guys they worked with.

The prospect of living at close quarters with Steve excited Tony from the moment that they met. Both had rugged good looks and superb bodies, and when Tony saw his skipper taking a shower just before the flight started, his circuits went into overdrive. He was determined to talk Steve into bed before the trip was out, and started sounding him out at the first opportunity.

"Steve, have you ever had sex with a guy?"

"No Tony, I'm not gay."

" Well you don't have to be gay. I mean a lot of guys in prison get fucked, that doesn't mean their gay, just realistic. They know that there is no chance of any women, so they just make they best of it. We are stuck here together for the duration of the flight, and you are going to feel awfully horny sooner or later. You might get by with your hand for a bit, but believe me the time will come when you want something more. What I am saying is that we will be fucking each other at some point in the trip so why wait until you are wanking yourself silly?"

The skipper thought for a moment before saying, "Ok, Tony, say I was feeling horny beyond belief, you're a robot, a very sophisticated robot, but a robot all the same."

"You're quite right," replied the navigator looking deep into his skipper's eyes. "I'll tell you the difference. The human ass isn't naturally equipped for being fucked, mine has automatic lubrication; I'd be the best fuck that you had ever had. I give the best blow job this side of the Crab Nebula, and when I fuck you I can adjust my length and girth to give you maximum pleasure. Oh, by the way Stevie baby, I forgot to say that I can keep it up for ever."

The Skipper managed to last out for nearly a month, but not only was Tony hitting on him with ever more powerful arguments, he was putting something in Steve's coffee to increase his libido. Steve found himself thinking constantly about fucking and being fucked by his fellow crew member, even at night he was invaded by vivid dreams of gay sex.

One day Steve showering, when feeling a surge of primitive lust, he started to massage his painfully erect cock. Suddenly Tony was beside him in the shower, taking the erection in his hand, he sunk to his knees while the water sprayed over both of them. The android took his skipper's cock between his lips, lashed the cock head with his tongue, then got down to some serious sucking. The human was in heaven, he had no strength left to influence what was happening, so he just leaned against the
