Searching for yaoi manga

I read a yaoi manga about a guy who got into a fight, and suddenly when his enemy want to hit him from the back, someone throws a water bottle to the enemy's head. The guy who throw the bottle end up to be a porn star, damn hot one too. The guy who was gotten into the fight tagged the porn star along and suddenly recorded a porn vid with the porn star. So yeah, care to hell me with the tittle olease, i don't know the tag.
