The alien was lying on the floor where he had fallen. He had a number of wounds in various places on his body from the explosion.
I needed him alive to help me get off Mars, so I had to attend to his wounds. He seemed totally unconscious, as I cleaned and stitched closed each wound, which was good, because I didn't know how to anesthetize him for the pain. He wore no space suit or clothing so that made it easier to get access to the damage.
His neck appeared to have gills on either side, which opened and closed slowly. It seemed odd to have gills on such a dry planet, but maybe he came from elsewhere In the galaxy.
His arms and legs were very long. Overall, I estimated him to be about 7 feet tall.
When I finished stitching all the wounds, I started cleaning the blood off of other parts of his body. But, when I reached his crotch area, I paused. I don't know what I expected, but not this.
Three appendages were attached to its body between his legs. They were coiled in tight spirals, like ropes.
Some of the blood from one of the smaller wounds above it had dripped down between several of the coils. I wrung the soft rag out in the bucket, the soapy, warm water sliding out between my fingers. I pushed one of his legs aside a bit and knelt between them.
Taking a deep breathe, saying "Here goes nothing", I started by rubbing along the surface of one of the coils, working the soft, slippery rag between the many folds of skin, moving carefully to get all signs of the blood off of the appendage. I assumed the purpose of it was the same as in a human man, although it was much much longer, maybe 2 feet in length overall and there WERE 3 of them, of varying lengths. What the hell do you do with three huge cocks, I thought? Did the females have three vaginas? When they get their period, do all three need to be dealt with at once? Yeesh!
As soon as I started rubbing the organ, It started to uncoil and straighten more, while expanding in girth as well.
"Oh, you like that, huh?" I purred, as the shaft grew. "No different than any man on earth I guess. A woman gets anywhere near them and they get big and hard and just want to fuck you."
This did make it much easier to clean, as the wrinkles had disappeared. It had dramatically changed shape to become a long, tightly curved, oblong shaft, a full 3 feet in length. It was pulsing about once per second and expanded in girth and length
As I cleaned my way out to the very tip of his organ, I could see that it had expanded into a small tight ball of flesh, surrounded by seven short soft tentacles positioned evenly around something that could only be described as a small mouth, but with no teeth. It had a circular rounded ridge surrounding the opening, resembling one continuous lip. The tentacles were soft, like smooth fingers, no suckers evident, with rounded tips.
As the appendage uncoiled and grew firm in my hands while I cleaned, I discovered that my body was reacting to this apparent arousal of his body. He was still fully unconscious, and the only movement on his body was from this enormous cock. (I had decided to think of them as cocks and call them cocks because they seemed to react like a cock did on any human man when a woman touched it.) I was a 30-year-old woman who hadn't had sex with a man in five years, so I guess it shouldn't be a surprise to get turned on by a huge hard cock, pulsing in my hand, alien or not.
I noticed that the "mouth" on the tip was now gaping open a bit and was dripping a pink substance that smelled of fruit, oranges perhaps. I was extremely curious as to what it tasted like, and for some reason I was certain it would not harm me, so I held the staff steady with my left hand and slid a finger into the end of the little mouth, capturing one small drop of the liquid. I brought it closer to my face to examine it and rubbed it between my thumb and the wetted finger. It was extremely slippery, much more so than a man's semen, more like a good silicone sex lube. The light citrusy smell made it feel clean and desirable to put in your mouth.
I touched the tip of my finger to my tongue. The taste was very different yet familiar at the same time. It was quite sweet, with a slight background flavor of a perfectly ripe orange (which I hadn't tasted in over three years). There was obviously something very different in this sweet liquid though. As soon as it touched my mouth, my entire body was engulfed in a warm glow. My breathing grew deeper, heavier. I reached down, unzipped my white uniform a bit and slipped a hand inside to cup my right breast. I could feel that my nipple was no longer flat. It stuck out rigidly, had doubled in size and was very sensitive to the touch. I moved the zipper down further, until the stop was even with my snatch. As I dropped my other hand down inside the jumpsuit and slid it between my legs, I realized my panties were now very wet. There was obviously an extremely strong aphrodisiac in the liquid. I didn't know how it worked on THEIR women, but with human women, if even a drop of this got into any one of them, this alien was definitely going to get VERY lucky, and in a hurry.
