Demon / Alien
I like to be abducted by an alien or a demon. The method of seduction I like is to have them befriend me and gradually lure me into a false sense of security. Your reason for abducting me is to 'turn me' to become one of your own kind. It is your kiss that does this. It also acts as an aphrodisiac in my body so it calms me from trying to push you away to begging you to fuck me for the first time.*
I like shapeshifting and transformations (so im open to TS fun) so the way is to gain my trust mimicking a human and just seduce me knowing you will turn me gradually. The reason for having me is to harvest human seed to mix with yours as your sperm alone cannot produce offspring in human females.
