I was very study minded in my childhood. I had no time for other activities like some teens do (jacking). But one incident changed my world. I was 18 at that time, playing football with my friends and I got hurt on my right thigh. I got home with a crying face. Mom saw and I told mom I got hurt. Mom was very caring. She took off my pants and saw the sore reddish wound. It was almost in my groin and was painful. She said first to have a bath and then she would bandage the wound.
I had a bath and came out of shower in my towel. Mom was waiting for me with the first aid kit in my room. Mom said to take off the towel. I said mom to wait so I could put on some underwear. Mom said that would hurt the wound, so I took off the towel. I was actually totally naked in front of my own mom. Mom took a cotton piece with spirit and rubbed the wound. It was like poking with pins. But soon I had a strange feeling. My pain was gone. I was getting tickling sensation and my penis was bulging.
I was standing and mom was sitting dressing my wound. Now my penis was fully rock hard. It was swinging right in front of mom's face. Mom saw my erection and said "oh my". I felt shy and said sorry to mom. Mom smiled and said it was natural. After some time mom asked if I masturbated. I said no. Mom said "that's very sad dear. Jacking makes you feel better and releases the tension". Surprisingly mom took my penis into her soft hands and moved the foreskin up and down. Mom used her saliva as lubricant. I was in heaven for a moment. pre-cum was oozing out of my dick. Mom taught me some tips and handed my penis to me. She wanted to see me jacking off.
I stroked my penis looking at my mom's eyes. It was pretty good. In that lustful environment my eyes fell on my mom's bust. I could see the upper part of the breasts as mom was sitting on her knees. I came close to orgasm. I hit a large load over mom's face. She loved it. Mom said "This is it. Now you know how to do it. I will be looking to see how you will improve". Mom watched me every weekend. She is my teacher.
