I noticed this post has hundreds of views and no replies. This, I fear, is because there are thousands of fans like us that love this tactic and no producers featuring it anymore.
Well, I just found one. Riley Reyes just released "Porn Bitch Showdown" on both clips4sale and her site
www.rileylovessex.com. It is scripted, but very well acted. She and Lyra Law do an outstanding job, and I sent her an email expressing my appreciation for her effort. I am not affiliated with her (just a fan), but I hope if we support her by purchasing the video and let her know how absent this subject matter is from this genre, that she will continue to make more products like this.
