She can't

Gabby had even of Xena getting all of the good fucking, she pulled Xena off Robby's cock and pushed her down to the ground. She slide up to Robby and held his cock in one of her hands. "Hey, Stud! How about you have some real fun? Bolndes know how to have fun." She pulled Robby's head down so that she could kiss him. With the other hand she plunged Robby's prick into her pussy. She didn't care if it was covered with Xena's juices, she was getting her man.

Robby enjoyed the kiss and the hot pussy that was holding his cock. His hands moved to Gabrielle's small, but perky breasts. Her hands romed his back and down to his ass, squeezing it. He enjoyed having Gabby thrust on him over and over again. He could feel pressure in his cock.

Now he had to choose. More Gabby or more Xena? Which woman would get his first cock juice? And where would he shoot it?
