Long time age I saw a comic that have a scene in which a man who is driver for a woman (setting in the back seat). The woman was kind of bossy and she was talking a lot then he becomes andry then stopped the car looked at her and hypnotized her then he order her to come and sit in the front besides him while sucking his cock later on there was a scene where they have sex in the bed and she fought a little bit but no use. It is more likely it is a dc comic but I am not sure.

Another comic happened in a castle in the old times a prince had a purple liquid if he put it in the head of anyone he/she will do anything that he desire.

Those two descriptions sound like they could apply to a lot of things, actually.

Anyway, I have no idea as to your second one. But your first one sounds like "Wildcats Ver. 3.0." which I think came out in the early '00s.

It's funny that you should say that you think it was a DC comic, as it was by Wildstorm Studios, IIRC. Wildstorm started out as a part of Image Comics and was its own thing for a long time, but the studio and the rights to all of its characters would be later bought out by DC. Which is how we got Martian Manhunter joining Stormwatch and Midnighter ogling Nightwing's ass.

Splitting hairs I guess, but I don't know if that particular comic was made before or after the buyout. Regardless, if anyone's still selling it at this point it would probably be DC.
