I home at last. It was a really long day. Beth greets me kneeling at the door: " Good evening Dad!" She help down my jacket and my boots. "I started to prepare your bath, 5 minutes and ready. Lilly already went rest." - You are a good little slave, darling. I Kiss her and hit her ass. She wash my body all over. Oh, Dad. The maidbot has arrived. Its charging in your room. When we finish the bath she help me with the drying, and ask with vigorous smile: "Do you need somethin more, Daddy?" while softly rub her tit. - Today not, I will try out Erica. She is disappointed and leave to her room. When I step into the room, Erica lie on her back in my bed. Beth probably play with her, and drain down her batteries. I step to her, rubbing her tits while I play with my cock. Rubbing my penis to her mouth than fuck her is missionary. She was a little dry (I think because of low charge) and her vibration pussy was also out of order. So in the I came on her tits by hand. When I go to rest I hear noises from Beth room. She is moaning, screaming silently while she masturbate. Tomorrow I have punish her. 2 times. One, for I didnt give permisson her for masturbate. Two, she drained the battery of Erica. I'm her Master now, better if she learns it.
