If you look up kiss possession on youtube there are a bunch of videos that look promising. So far I found two that I'm pretty sure are new.
First one is from Candy Strippers (2006) with a bunch of aliens disguised as hot nurses who possess people by transferring a slug into their mouth. You get a girl on girl one which is unfortunately mostly hidden but is something: ihttps://www.youtube.com/watch?v=DCTuYOfjmZ8&t=45s
Next one is from Monster Busters (2009). Shadow entities possess people and they continue to possess others by kissing them. This youtuber uploaded a video with a bunch of the kisses: https://www.youtube.com/watch?v=X6yrk6S8xMc
