She rested her head back on my shoulder. I tried to drill her ass with my dick. She looked at me.Me: What happened? You said you would cook something ...o eat, right?Mom: I am very much tired.I turned her towards me and looked at her.Me: Somebody asked me if I am tired.Mom: For the last one week, both father and son have been fucking me all night. And from the last night, you have been doing me continuously. I am not whore.We looked at each other for a moment. I smiled and pressed her waist. She.
