I think Public Sex is going to be bigger than many realize. It's certainly my favorite when combined with gokkun.

Idea: Semen starved MILF leaves the house during the day and tries the suck/swallow the whole town. Arrives home at the end of the day, happy and refreshed and ready to cook dinner! The public venues are endless.

Idea: Semen starved female office workers go into 'special restroom' where gloryholes have been constructed, have 'lunch' and return to their desks smiling and refreshed.

The scenarios are endless; just keep it classy and leave out the misogyny.

You are totally onto a great wave.
I also think public gokkun is where its at. I would LOVE to see a chick get load dumped on her in public. Seeing the utter disgust of the female onlookers would also be part of the turnon, as she just keeps swallowing load, after load, after load.

I don't care for 'dumping on' a woman's face bukkake style but an unexpected ejaculation can be sexy. The most memorable scene in my mind was when Britney Of Cumtrainer was blowing her husband (as always, unfortunately); the first squirt went into her mouth, she tilted her head slightly not expecting the second squirt to be more powerful than the first and it went across her nose, lip and cheek - unexpected, fun and sexy.

Guys standing around, jacking off while distracted by their neighbor's dick and dumping their load on the woman's face (if they even make it that far): not sexy at all .

I know I mentioned some of this in another thread but I'll do it again here:

Blow Job Bars (hetro) in the Far East; probably have them here for all I know but are a big secret for obvious reasons. A 'roaming camera operator" going around and capturing the action. Be sure to hire someone who could keep their mouth shut and just operate the camera with skill and imagination.

MILF or 'girl next door' leaving home for the local adult arcade to blow, swallow, and fuck as many as possible. Massive cream pies and no semen wasted. Show her arriving, departing and extensive outtakes. No mouthy, stupid camera operators-directors and a woman who really loves what she does.

Recent news item where a McDonalds employee (18yo female) was setup by her female boss to blow the boss's boyfriend (boss was fired and boss's boyfriend went to jail); how about a McDonalds (?) employee (female) blowing and swallowing every male who came into the restaurant through a gloryhole - just an idea. Endless possibilities. I'm a big fan of the 'girl next door' types. Aurora Snow and Brandi Belle are two of many that come immediately to mind.
