My mother found my sex doll.

I'm Johnathon 20 going to the local university and doing well, except in relationships with girl. I live at home with my mother, father and sister, we aren't rich but comfortable. I've always done well school wise and didn't have many friends, I'm a nerd, geek or a smartass according to other I went to school with. Any I do tutoring of these same people, so they can pass their subjects. That's how I earn my money, some don't want me to tutor them, but their parents disagree. Anyway not great with girls so I got a sex doll via the internet and had been using it for several months. When my mother Cheryl 39 caught in the act, not happy with me having a sex doll she took it and busted it apart throwing into the rubbish in a garage bag. Then returned to have a talk with me, I was expecting a major telling off and was hoping she wouldn't tell my father. Instead she said I shouldn't use a that thing, as I had her to help me. Confused by her response I just looked at her, so she said you could have come to me and I would've helped you. Still confused I asked how, I would've taught you how to fuck and any relate to women. I wasn't sure if she meant me fucking her or something else. Seeing my baffled look on my face, she stripped off her clothes in front of me and told to undress and lay on my bed. She started to stroking my body and worked her way down to my cock and then sucking me off. Then mounted me and fucked me until I blew my load inside her, I was in shock and heaven at the same time. She then told me my father wasn't interested all that much in sex since his car accident and she rarely get sex from him about twice a year she added. Also she said I will help you sexually and it will be our secret and you'll be helping me sexually instead of me having to masturbate to get off myself. That was in November and I'm getting regular sex from my mother, I've rarely asked her for sex. Because she does the asking. We nearly got caught by my sister once, but she didn't enter my room just called out if I've seen mom. I answered no and she left, we finished our fuck and showered together.
