When I was 17, my mom and I started fucking.

It started when she got really horny after sex with my dad (He has a small dick and he cums fast). She came to me when I was playing video games, dressed in lingerie and g-string stockings. I was used to seeing her like this, because she wears bikinis. She's seen my cock because she saw me get out of the shower once. Anyways, she came down to me and sat next to me. She started to massage my back, and one thing led to the other and we fucked. We continued to do it until this day. We do it every day, before my dad gets back from work. My dad doesn't know about it.
