All of them

"How about all three?" You groan, feeling yourself push past the point of no return. You quickly grab a hold of your cock, stroking it furiously in front of your submissive girlfriends face.

Stacey's face lights up with glee at your choice and she opens her mouth and extends her tongue out lewdly at you. An arm pushes underneath her big tits making them look even fuller as if to catch any spurts of cum that happen to miss their mark.

"Give it to me Master! Paint me with your hot, creamy spunk!" Stacey cries.

"FUUUCK!" Your orgasm reaches it's crescendo and you feel the first rope of cum shoot out and land into Stacey's open, awaiting mouth. The next two splash against her cheek and chin, while the remaining spurts splatter atop of Stacey's perfect globes, pooling and dribbling down their curves.

Post high, you take a minute to stare at your cum covered girlfriend, appreciating how hot she looks with her mouth full and rivulets of it running down her naked body.

Stacey looks back at you with those large innocent brown eyes and swallows down your load with an audible gulp. "Have I pleased you Master?" She asks, running her hands over her breasts, collecting your cum before absent mindedly lapping it off of her fingers.

"Fuck yes! That was so hot babe!" You cup the side of Stacey's face that isn't covered in your cum and kiss her on her forehead. "Amazing!"

Stacey quivers and bites her lip with a delighted smile. Her thighs wriggle together like just your praise was giving her pleasure.
