William loved the post orgasmic glow that was coming off of them all, especially Jake who seemed incredibly happy about all this. "Care to make a trade, son?", he asked as he smirked to him, "Your little sister seems quite eager to get a taste of her little brother and I'm sure you will enjoy her tight body. I tell you, every time I spend time with her it feels like I'm taking her virginity again, it's amazing". He laughed and smiled down to her. It was true that all the girls had something special about them, Avery's lack of a gag reflex, Amy's unending tightness, Holly's breast milk he counted as he loved it. He let his hand gently cup Holly's tit as he waited for his son's answer.
