Custom-built: Poison Ivy vs Robin. Robin being caught in your vines, incapable to budge. You walk telling that you should kiII him but you have a better plan, you are going to own him. So you give him a kiss than tease him about it. Now he is completely controlled by you, thinking he is in love. You make him get down on his knees. After kissing your feet, you make him worship you. Then tell him he can have another kiss if he becomes completely yours. I think it would be super hot to say that your lips have a special toxin that makes Robin fall in love. From there some reminders that he has to earn the right to another kiss, by kiIIing Batman or helping you steal or something of that nature.
