What aliens do to you once you have been abducted in to their space craft. Many abductee's claim this has happened to them, usually the alien probe is inserted in to the anus.
I cant explain to you why they like that particular intrusion.
"i got abducted by aliens in my sleep last night. I went in to their spaceship and they probed me up"
"that fuckin green alian sick fuck stuck his probe in my ass"
"if aliens abduct me, my over and under shotgun should end their little probe party"
