Mom protested "we can not have sex, I am your mother this is so wrong!" "You can have strangers fuck you and cum inside you, then you can let me fuck ...ou" I said as I pushed my cock into mom's tight little pussy. "please, do not do this, this is not right." I started to pound mom's pussy hard and she started to like it. Mom was meeting my thrust and really getting into it. I was like a porn star pounding away, and I could tell mom was nearing orgasim. I kept up for another minute and was. One day when again I went to Bank, I went to her cabin, she greeted me and offered me cup of tea which I readily accepted as I thought this would give opportunity to talk to her.I asked about her family, her husband is also in the Bank but in PATIALA and comes on weekends. Her child is in Hostel doing Engineering.She asked about me I told that I am bachelor, then the lucky day came. It was about 7 PM , I saw her in one store she was buying groceries. We exchanged pleasantries and I offered her. She hoped because the nanites were so eager to help her that they had taken the initiative to paint her nails as well.With her heart in her mouth she wriggled her fingers, flashing the ruby red nails in front of the mirror. She said with a lopsided smile, “Love what you’ve done but I think this is a little over the top. You see, I’m going to the office and I think that it would be just a little too distracting.”In an instant her nails changed into their natural color and she smiled warmly to. Now let us geton with some serious training... Stand up? she said and then she turned away tofind some thing in the bag. She came back with 2 collars and 2leashes. She put one collar on my neck and the other at top of my balls. Soonmy balls turned purple. Then she attached one leash each to the collars. She then tied the leash form theneck collar to hook on his wall behind and turned the other around a doorhandle. She gave an evil smile and said ?Ready ?The she started pulling on theleash.
