It features aliens with telepathic powers and mutating powers to create all kinds of shapes/tentacles with their forearms and hands. The telepathic part can mess with the humans minds and induce sexual feelings and vivid fantasy's. While mutating hands provide an unlimited supply of shapes and textures. The aliens would be like similar to a human being in shape and form but have minor adjustments.
The story is there is a trading vessel running though the galaxy and the aliens want to abduct the humans for testing purposes. The aliens are the first to capture live humans and put them in containment cells and begin to run studies and do brain analysis. While doing brain analysis they see what the humans are thinking at the time in pictures and memories. And they see the humans have lots thoughts about sex which is unknown to the aliens. So they explore and tell them to have sex or they will be tortured. So the humans have sex (sex scene) and its fairly normal. One of the female aliens finds this very erotic and starts to talk to a different woman in one of the containment cells through her telepathic powers and induces sexual urges in the human woman to fuck the alien woman. The alien sees she likes shapes inserted into her vagina through her thought process. So the alien ask if she can do further research in a different room where she can concentrate (less noise from the couple fucking) So she take the human woman to her room and inserts her hand shaped like the images she saw while she was fantasizing. (sex scene) Then the alien tries her tentacle shape which the aliens use for sex and finds she loves it. They go at it and some way though the act she induces a fantasy which drives her wild and she has multiple orgasms. (possibly add a squirting part here)
Then later the humans are sleeping and the aliens begin to do their business. And go to sleep. The next morning they arrive at the aliens home planet where they do further studies on the humans but find out that the aliens had sex with them and they are banished from their planet and have to fend for them selves stealing and looting other ships for supplies. And selling them on the black market. The aliens like their new sex toys though and they work together to ensure their survival is the universe and fuck often. (ending an a gangbang sceen)
Of course I'd have to come up with some specific lines and what not for it.
What do you think for a porno it would have lots of effects and lots of space battles. It would be like Star Trek Porn or something. This would just be a basic guideline for the story.
Do you think it's a good idea? This is the first draft of the basic story line.
