The saucer picked up Aiko in the early evening as she was walking home. At first she didn't see it for it was descending behind her without lights and the propulsion system was silent. It was only when it was almost upon her that she noticed something was wrong and by then it was too late. The aliens were upon her swiftly and almost immediately she was rendered unconscious.
When Aiko awoke again she was naked and strapped to a table inside the alien ship. Her legs were held in something like the stirrups that doctors use and it held her legs spread wide apart. This exposed and opened her pussy and she soon noticed there was something to see her exposed that way. Since Aiko had a strong exhibitionistic tendency, that exposure immediately started exciting her sexually. Strangely she did not feel any fear the aliens would hurt her, perhaps because if they had been going to do that they would have done it already.
In the room with Aiko were three aliens. Two were male and one was female, it was obvious which was which because all three were naked. Their skin color was green; almost the color of lettuce leaves, but a bit darker. The aliens had hair on their heads but nowhere else, their hair was green, too. Aiko wondered why the aliens were naked, maybe they didn't wear clothes. In a way she was glad they were naked for she thought they were actually quite attractive despite their strange color.
As Aiko lay there on the table strapped down and exposed the aliens were grouped together against one wall of the room she was in. They talked together in soft, high pitched voices, the male voices seeming the same as the female, and of course Aiko could not understand a single word of their alien conversation. The aliens continued to converse together for about 5 minutes and then they all turned and approached the table to which she was strapped.
The three aliens started touching and exploring Aiko's body. Their hands felt cool and smooth to Aiko, not unpleasant at all. Despite the fact she was strapped to the table she wasn't afraid, instead she found herself getting excited by the aliens touching her. The table upon which Aiko was laying was then lowered until her body was just at the level of the alien genitals.
One of the male aliens moved so that he penis was right next to Aiko's face. She studied the alien organ for a moment; it was similar to a circumcised human penis except it was green. The head was a deeper and darker green than the shaft but Aiko did not find it in any way unattractive. Instead the alien's penis excited her as much as the cock of a human male would have. The alien's cock was already erect and he moved it toward Aiko's mouth as if he wanted her to suck it.
