Of my 3 programs Erotic Revenue will have the longest tube clips (and in HD). Porn Nerd Cash has many longer than 5 minutes, too. Aggressive Dollars is new to me so there's not much there (yet).
I would recommend signing up for all 3 tho. Contact me for some more clips, too, I have many that are not on the APs yet. Wicked Sexy Melanie would be great for you plus many others.
Good luck as always!
