My dad left my mom when I was 13 and for the longest time I would hear her crying in her bed at night and she became like a zombie as she never got enough sleep.
2 days after my 14th birthday I came home from school and mom was not in the kitchen as usual, I went upstairs to my room and as I passed moms room I saw her naked gagged and handcuffed spread eagled on her bed. My first though was that she had been attacked and raped, I ran in and took the gag out of her mouth and I could see the key to the handcuffs on the floor I grabbed it and said don't worry mom I will get these off.
This was where it got weird, Mom said well yes you could set me free but I am cuffed and vulnerable now and i cuffed myself like this 30 minutes ago. God was I shocked as the implications got through to me and despite everything I developed a raging hard on. Within 5 minutes I was pounding away between my mothers legs and pumping the first of many loads of cum deep inside her hot c**t.
Turns out my mom has always been a sub and losing dad meant that not only did she lose her husband but also her master. Gradualy over the next few weeks I found out what moms deepest darkest secrets were she loved being humiliated (she told me she had been dripping wet at the thought of me finding her on that bed after she had cuffed herself there and deliberately left the key out of reach so she couldnt change her mind. Sh loves being caned spanked and whipped even to the point of drawing blood, she adores having her pussy lips clit and nipples tortured, and me well I have learned how to be a VERY severe master, mom makes a great punch bag and I love her on her knees begging for my cock.
