This guy here runs a porn site for semi amateur porn. He's always out at the clubs to recruit new, young cute talent. Your boy and his boyfriend decide they want to make some quick extra cash and agree to both go film for his site with the agreement that they'll both just jerk off for the camera and that's it. The problem is, once it's your boy's turn and he's alone and tempted with this guy's dick, he just can't help himself.
We can discuss how we want to handle things in the line after. He could hide it from the boyfriend and ask to film something solo too when things are done so the boyfriend doesn't know. They could strike up something where it becomes more regular and he comes back for more. Or he could keep shooting more hardcore scenes and the boyfriend just never finds out because they get loaded onto a different website. Or he could end up telling his boyfriend he wants to get fucked by different men on camera and he needs to deal with it! We can go any direction we want.
If you're interested, let me know who you'd like to play for your boy!
