I was 13 years old and my older sis was 15. She looks pretty nice and she has small breasts with a fine body. One day I had basketball practice but it was cancelled so I went home.
When I got home I thought I would surprise my sis who is usually alone because my parents were at their work places. I went into the living room and I saw my sister naked on the floor on her back while she was watching porn.
I immediately got a hard on she saw me and asked 'do you masturbate?' I never heard of it before and I never ejaculated so I said 'no, what is it?' And then she says 'come here' I sit next to her on the floor and she tells me to take my clothes off. I was pretty nervous but I did so. I layed down and she sat down with her knees on the floor on each side of my thais. She started to give me a hand job and this was the first time I experienced such intense feelings. In just a matter of minutes, I cummed all over her petite breasts. She licked her nipples of all the cum and she asked me 'do you want to try?' I said yes being so curious. I licked my own cum off her chest. It was a satisfying taste.
I will never forget the words she said: 'you are now a man'
