Hi, long-time lurker here, found this on Pornhub a while ago, and I think it fits.

In this nice chunk of Lesbian Theatre, one woman forces herself on another after chasing her down. However, as the first kisses give way to more, the "victim" becomes more and more receptive, Lady-Love ensues, and at the end, you see them both pursuing a third woman, implying they're now working together.
Implication is that the kissing has a wonderful little Charm/Hypnosis effect, and that further kissing means further charming. As an added bonus, that little end scene implies it's something that can (and will!) be spread to more and more women.
So yeah. Check it out.
ps. Been having trouble getting the vid to load. Let me know if anyone else encounters the same problems, I'll try to scrounge up some kind of DL.
