Cum in Arya's mouth

You feel your impending finish as you look down at your little sister dutifully caring for your cock.

"Little one, I'm going to finish now. I don't want you to be surprised. When I do, taste it. Hold it in your mouth like a good girl does."

And you explode, half a gallon of hot, fertile seed rips into Arya's waiting mouth. You place the tip of your cock on her bottom lip and continue squirting into her open, receptive mouth. Her eyes stare up at you, in praise and admiration as her mouth fills with your come.

"You're beautiful, sister." You placate her. "Never have you looked more womanly than right now, servicing a man. Your loving brother, no less." You smile at her and she moans in appreciation around the mouthful of jizz.
