My mother introduces me to sex

My mother and I had been living alone in our small house in the country side for as long as I can remember. We only had each other (although our recent addition was a little kitten called princess) and always got along perfectly with little to no fighting, we hugged alot and spoke about everything. She would always demand a kiss on her cheek before I left for school in the mornings and another before going to sleep. I was 15 at the time with average looks, my mother was in her late 50’s. She had long blonde hair down to her shoulders and a curvy figure, a little bit chubby. Back then there was not much sexuality in the air among the other kids at my school, some of us would still giggle at words such as “penis” and “vagina”, others had a partner but would only ever go as far as kissing and holding hands. We didn’t have playboy mags or the internet for porn. Summer holidays came and I decided to stay at home with my mother to just sit back and relax with some television and soda, most of my friends all went to camps or trips; I honestly couldn’t wait to just stay at home and do nothing. I didn’t have to worry about homework, I didn’t have to worry about getting up early to get ready for school, I didn’t have to worry about anything.
It was extremely hot to the point which you could pass out from dehydration if you didn’t drink enough water and absorbed too much direct sunlight. I’d walk around the house with some old donald duck boxers and a thin white t-shirt, my mother would only wear a long aquamarine coloured shirt which would almost reach her knees. She didn’t even wear any bra or undies, I never found that strange because it just simply has always been like that when it wasn’t cold, besides, I never saw my mother in a sexual objectivity. I remember when my mother used to bend over to pick something up from the floor and I would see her hairy vagina i’d nearly giggle.
Not long after the holidays had begun, I had found out about the pleasures of masturbating when I noticed how excited I got after seeing the naked women in the last pages of a newspaper by accident. They were prostitutes and had a little black and white picture of themselves exposing their breasts next to their advertisement, I don’t know if everybody in their respective countries had this in their newspaper. From that day on I did not brush my erections off as something annoying that would prevent me from peeing or made an awkward tent in my underwear. I never found out why I suddenly built an attraction towards my mother, perhaps because we were so extremely close and she was just simply the only female around me at the time. I knew it was not completely right to have sexual feelings towards my own mother but I really didn’t think much about it, there must be people out there with the same fantasies and some probably even acted on them. I wanted to act on them aswell.

I was awoken by the intense beam of light which slipped through a crack in the curtains. I instictively grabbed my phone to see what time it was. 11:30. It was wonderful, being able to sleep so long not having to care about getting up early. I felt my hard uncut cock rubbing against the sheet, the friction on the head of my cock is probably what made me hornier than normal with this typical morning wood. The sheet must have pulled my foreskin back and forth while I slept, and it most likely was the cause of my wet dream because I saw a white cum stain on the matress. I didn’t really care about it, my mother would probably just think it was swet due to the heat and all. I adjusted myself a bit better and started to masturbate with my eyes closed and cock in the open.
“Hey hun, don’t mind me, I just need to put yesterday’s laundry in here. Dried so quickly!” my mother said as she was walking around in my room with a bunch of shirts and other clothing, completely catching me off guard and pretending i’m not furiously masturbating my 6 inch penis. I instantly threw the sheet over my cock and changed to a sitting position.

“Oh uhm I-“

“Don’t worry sweetie, I knew it was just a matter of time before you started with that, it’s perfectly fine.
