When your bumping uglies with a broad doggie style right before filling her pie with your cream you quickly take out your mushroom tipped yogurt slinger and cum in your hand discreetly, but they key here is not letting her know you Busted your load in you're hand, you just play it off and keep going and then a few seconds later you slap her in that makeup caked face with the hand full of semen (she's probably going to start fucking losing it so make sure you're holding on tight) then keep on smashing that ass cause it will then turn into a rodeo until she bucks so hard you fall off. Then run cause she'll be ready to chop off your beloved tallywacker.
