Both great choices but will go with bukkake. This is because of the larger quantities of cum in bukkake and can always do other anal training with or without cum.
They’re both hot as hell but I’ve gotta go with Bukkake! It’s so hot watching cocks pump load after load of cum into an asshole and when it drips out. Especially if another whore is there to eat it up! But bukkakes are amazing because you have this slut who’s the center of attention. All those hard cocks jacking off with the thought and intention of cumming all over the sluts face. At that point, she’s nothing more than a beautiful cumrag. I fucking love it!
