Servicing Momys Needs

I'm living with my mother since I can remember I never met my dad. I have a very good relationship with mum. She always tried to make me have a good life in terms of money. She is also pretty strict sometimes and over the years I learned to not talk back. It started when I was about 14 years old. It was on a weekend and I was sitting in bed playing with my gameboy. It was about noon when mom knocked on my door. I told her to come inside. She entered my room. Her long brown hair was messy and she was wearing a very long kind of tshirt. She took a few steps closer to my bed and lifted her shirt up over her belly. She wasn't wearing any underwear and her hairy pussy was exposed. I've seen her naked a lot of times since we only have one bathroom and sometimes needed to go to the toilet while she was showering. I was confused and asked her what she was doing. She looked at me said nothing and came closer. She was now standing on the side of my head. She lifted her right foot and placed it besides my left shoulder. I asked again what she was doing when she grabbed my head with her palm in my hairs. She pulled my head closer between her legs and my mouth was only a short distance away from her pussy. "Lick me" she said. I was confused and said I don't want to. She pulled my hair harder and said "I'm not asking, lick me". Before I could say anything she pulled my head and pressed her pussy against my mouth. I didn't know what to do so I started to lick. I licked her whole pussy until everything was wet. "lick here and don't stop until I tell you to" she told me and she pointed at her clit with one of her fingers. I put her mouth over it and licked where she pointed before. "Just like that" she said. I did as she told me and after some time she started to moan softly. "Keep it up" she said and I felt my tongue getting more and more tired. I continued and a short time later she began to moan loudly. She pushed my head even harder into her when she started to cum. She softly rubbed herself against her tongue as she let out lustful noises. I felt my throat getting wet and the neck of my tshirt too. She rubbed herself a few last times until she let go off me. She came and squirted on me wetting my tshirt and part of my bed. She pulled her foot of my bed and stood besides it. She told me that I did good and that I needed to lick her more often and after that she left my room again. After that day she would regularly tell me to get my head down and lick her, which I did. Sometimes she came at random times but most of the times I needed to lick her in the morning before school. After I ate my breakfast she sat down to eat hers. She would then expose herself and make me lick her clit while she was eating her breakfast. I was never allowed to stop until she came and she squirted most of the times. After some times she would also pleasure me but that is a story for another time.
