My mom caught me masterbating

For one month mom and me were all alone in our house.Mom used to sleep at about9 in her bedroom on ground floor. One night I went at 9.25 to my bedroom in 1st floor.Since I was alone I didn't bother either to lock the door or switch off the bedroom lamp. I lay naked and started masturbating. After about 5 minutes I heard mom asking mildly " my son what are you doing. I didn't hear even her footsteps.With out any further comments she left the room.
Next morning I was embarrassed to face her.But she acted as though nothing special happened previous night. I was happy. But before dinner,she asked me to say goodnight to her before I go to sleep. I was surprised to hear this strange request. After dinner I went to her to say goodnight.She was sleeping covered fully with a bedsheet.I sat on the edge of the bed.She told me " my sweet son what you were doing yesterday was nothing special. Before getting married 90% of boys and 75% of girls do it.Only one thing you shouldn't over do it since it will spoil your health. I instantly replied that I do it only once a week on Saturday nights and I think it was not overdoing. Mom agreed
and asked me to lay on the bed which I did.I pleasantly found that she she was fully naked below the bedsheet.I could not believe that I was talking to her for about 15 minutes just one foot away
from my fully naked mom. She removed the bedsheet and commented " It is too hot and in summer I sleep fully naked. Why can't you remove your dress" I did it with pleasure. I asked mom " My darling mom you belong to 75% girls who
masterbate before marriage? " Mom with a bit of embarrassment agreed.Then she asked me " whom you imagine while you masturbate, your girlfriends ? " I replied I haven't any girlfriends. Mom asked me so you don't imagine anybody. I replied no, I imagine somebody but I am shy to say whom.Mom replied don't be shy you can tell me anything. I hesitatingly replied " I imagine you only.Three years back when I was only 12 years old when we bathed together seeing your naked body I felt sexual urge towards you. So when I started masturbating when I was 14 I started imagining you.Hearing this mom hugged me tightly and asked me " which part
of my body you like more.I replied your
semi dark fleshy thighs and rounded buttocks. Mom was happy to hear this. She asked me " do you like to actually do what you were imagining. I told yes. She told then o ahead.with my right palm I massaged her from her foot to upwards to thighs and buttocks. The areas were too smooth and extremely hot.I massaged her pussy surrounded by black thick pubic hair.On my request she fondled my half erected cock and made it fully erected.On my request she
took the position away from my face exposing her buttocks towards me.I inserted my cock through her ass Crack
and started making to and fro motions
in the area from her asshole to the bottom tip of her pussy.After receiving her guidance my cock reached her pussy hole and I made to and fro motions in her pussy hole.We both were enjoying. Then she lay on her back and I jumped on her and inserted my cock to her wet pussy . It went on for about ten minutes until my cock cummed. During this period I was giving her French kisses. We cleaned ourselves and slept.
These actions we carried on every night for the remaining full month.
