Her ass

"Well, I don't want to risk getting you pregnat until after our trip to St. Mungo's just in case so I think I'll just take your ass before we go" Ron explained to his slave sister

"Whatever you want master. I live to serve you and your cock" Ginny remined him.

"That you do, you little cock slut" Ron stated as he moved to the back of his sister, placed the tip of his cock to the puckered back hole and pushed in without mercy which caused the slave to cry out in pain. It was absolute agony at first for the petite red head but the more he trusted in, the more she pleasure she found in it.

"Oh, master! Your cock feels so big in my ass! Oh it feels so good master!" Ginny moaned

"Yeah, I bet you like it in your ass you flithy whore!" Ron whispered in her ear, which caused her to shudder.

The more ruthlesy Ron pounded his sisters ass the more she felt the need to cum and if she didn't at least ask for permission then there would be hell to pay.

"Master! Master! Please may this cock addicted slave cum!? This ass fucking is just too good master!"

"No cumming allowed from you slave. If you cum then when we get home, you'll be punished dearly"
