There is a artist who goes by the name "AnyThingGoes" who's art is MOST spendid and very arousing! He is on tumblr and likes to make sexy animations, such as "samus and face huggers" or a raven getting her face plowed. If you're looking for some HOT smut I highly suggest "AnyThingGoes" *Sings the name like he's about to sing the fucking song.*
