I would like to set up a fake cuckold session with a local dom. There are certain things that are great in fantasy but not in real life. Example; I would love to be tied up and forced to eat fake cum out of a providers ass. I would not want to eat real cum, nor do I want some other dude in a session with me. It's my fantasy.  
They actually make fake cum for the porn industry. https://www.amazon.com/dp/B00AFOR4EG/ref=cm_sw_r_cp_dp_T2_tiMCzbBY9VY02

Wait, all those Bakukake shots are not real? ?!?!?

Submarines are full of seamen.

which is what I always figured the fake cum was anyways.

I shot a scene where we worshiped the cock of a horse god then rubbed the god's semen all over us while trying to impregnate a woman...lol anyway we used the powdered j-lube and kept the consistency thick so that it looked milkey like semen. It didn't really taste like anything either! Might work well for your scene???

You can purchase piña colada mix from the grocery store. It's basically the same thing. They use it for porn all the time
