Robin, aka Dumbslut

Both girls desperately raced to where the ball had landed in the far end of the yard. The sight of their jiggling asses is fantastic as they go to the ball. The race is pretty equal, but in the end Robin reaches the ball first and picks it up with her mouth. When she turns back she goes slower, as she no longer needs to race. While in her face the disgust towards the ball is clear, her new-found obsession with cum carries her through. Julia follows her, looking disappointed.

When Robin reaches you, she lowers her head and deposits the ball at your feet, like a dog, and looks up to you with expectant eyes.

"Good job, Dumbslut, you win", you tell her as you lower your pants, revealing your waiting erection pointing straight at her face. Her eyes grow wide as she sees it before taking it with her hands. She begins to jack you off, slowly at first and then faster as she prepares to suck it. Looking over, you can see Julia is looking at the show with a defeated stare, slightly playing with her breasts.

Soon, Robin is sucking your dick vigorously, intentionally deep throating you in a bid to make you cum faster. Unfortunately for her, you actually still have quite a bit of resistance from fucking Julia earlier. Through your groans of pleasure, you see a small plastic rod lying on the ground, and get a fun idea.

"Julia, grab that rod and fuck Dumbslut's ass with it", you tell her, deciding she should be involved in some way and it would be fun to have Robin be fucked in the ass as she sucks you off. Julia immediately nods and obeys, grabbing the rod.

"Yes, Master", she says as she walks to you. She then sits behind the kneeling Robin and takes aim with the rod. As Robin keeps up her job, Julia jams the rod into her ass, causing her to yelp as your dick is far inside of her, sending waves of pleasure to your dick. Julia then begins to fuck Robin's ass with the rod.

As this goes on, Robin begins to moan, brining you even more pleasure as you near you edge. You groan as you prepare to pump your cum, and briefly wonder whether to pull out or cum inside of her mouth, before deciding it will be more fun to cover her face in cum and see her desperately scoop it up.

As you finally reach your edge, you pull out of her mouth and jack off the last bit necessary for you to come. Your dick covers Robin's face with cum as she opens her mouth wide to catch as much of your cum as possible. She then licks and scoops as much as she can from her face as it slowly drips to the floor. This gives you the idea to later have her and Julia eat you cum out of a dog bowl.

Robin the suddenly moans loudly, and you realize she is having an orgasm. Julia has not stopped fucking her ass with the rod, and this brought her to an orgasm. Robin's face of pure ecstasy, still covered in cum, is a sight to behold as you put your pants back on and tell Julia to stop, but leave the rod jammed in Robin's ass. You then wonder what to do next as you look around the yard, and then through the windows of the house.
