My 15th Birthday Present From Mom

This confession took place on my 15th Birthday (15M). My mom had me when she was 16 and my dad was never part of my life. I was raised as an only child to a single mom and was a real mommy's boy and my mom was very protective over me. Growing up i was used to seeing mom naked as she rearly wore much clothing around the house and more often than not we shared a bath together. It was actually during one of our bath's when i was about 12 that I got my first hard-on in front of mom. She was very understanding about it and when she spoke to me about it later that day she asked me if I had started masturbating, to which I replied YES. She asked me what I used to think about when I masturated and if I would cum when I jerked off. I had always been open and honest with my mom about anything and everything so i told her that I always pictured her and her beautiful naked body. Mom said that she was actually flattered that someone my age would fancy her and asked if I ever thought of sex with her when jerking off. Again I said yes. She told me that she wasn't willing to allow any physical contact between us but if I would like it she would let me jerk off with her watching and she would be naked for me. I told her i would love that and told her i loved her and she was the best. She gave me a kiss on the forehead and to let her know when I wanted to give it a go. Fast-forward to the day of my 15th birthday and mom and i were having a bath together. I had a massive hard-on which mom obviously noticed. She then asked me if I wanted a special Bithday g*ft now that I was all grown up. I said yes please and asked what this g*ft was. She then explained my special g*ft and the conditions i had to agree to in order to receive the g*ft. She told me that she was going to play with my cock and make me cum but i wasn't under any condition allowed to touch her but she would be able to touch me. Also, there would be no penetration. I couldn't believe what she was saying but was happy to agree with her offer. She stood up and told me to do the same, so i followed her instructions and stood facing mom, my hard dick pointing straight up to the ceiling. She reached out and wrapped her right hand around my prick making me gasp and slowly started stroking up and down. She moved even closer and started to rub the head of my cock through her pubes and over her clit and between her pussy lips, squeezing her thighs together and sliding my dick between her thighs and along her slit giving me a pussy job. She could sense I was close to cumming and took my cock in her hand againg stroking and rubbing on her clit and pubes until i shot my cum onto her black pubes....
