I think I am going nuts trying to remember what story this scene is from: The MC, who has invented a VR blowjob machine that allows users to trade blowjob sessions, is recording a session with an Asian Adult Star that I think he met at an Adult Toy convention in Las Vegas. After the blowjob session is finished, it leads to full on sex. I also want to say that the MC's girlfriend knows and encourages the MC to get the blowjob from the adult star.
Thanks for any help.
