I have a very special relationship with my mother. We both are lesbians and we have our own partners but some times we still like to have sex. No one knows about this, only my mom and I. A few years back I gave my mom a dildo strap on as a birthday gift, but we never had the opportunity to use it, so my mom promised me she will only use it me. After 2 years I finally was able to fuck my mom with it, and it was still sealed in the box. My mom kept her promise.
