So let's just get this out of the way. I'm 5' tall, 120 pounds, long dirty blond hair, and have 32DDD breasts. I'm also adopted and look nothing like my family. When I was adopted I was 12 and I came from a pretty rough home previously. Mother ran out, father overdosed and died. Yeah, it's tragic but I've been over it for some time.
As I said, I was adopted when I was 12. My adoptive family had a son who was 2 years older than me. When I was 13 I hadn't quite grown into the bust I have now. I was somewhere between a D and DD. If you know who Katee Owen is, you can get an idea what I look like naked (though not so much then and definitely not in the face). When I was 13 I saw my adoptive brother masturbating without him knowing I saw him. His room was in the basement of the house so it was easy. He wasn't anything huge or anything. Just average, but uncircumcised. It excited me to watch him jerk off to some playboy or penthouse or whatever it was, lying in bed naked, until he shot all over himself and then cleaned himself up with tissue. I quickly found out he did this nearly daily and after a couple times, when I knew the parents weren't home, I "accidentally" walked in on him. he was pissed, or more embarrassed probably, but I just calmly walked over to his bed and told him I'd like to help. He told me that it was disgusting because I was his sister but I told him I really wasn't and he knew that and I took off my shirt.
I was wearing a red bra underneath, and when he saw it his cock, which was slowly going soft when I entered, started to get hard again. I told him no one would know and asked if he wanted me to take it off. After a long hesitation he admitted he'd been curious about seeing my large breasts so I showed them to him and told him he could touch them. He did and I grabbed his hard cock and started stroking. It wasn't long before he shot spunk all over him and all over my shorts. I quickly went up to change.
The next time I only wore my panties. We did this for two or three more time before I went down on him for the first time. I loved the feeling of him pumping spunk into my mouth. After that it became a daily thing. I would blow him, let him spunk in my mouth and swallow it. He would finger me and use items on me and eat me out, but we never had actual sex. Eventually he got a real girlfriend and stopped doing stuff to me an eventually I stopped giving him head. To this day we don't speak of it, but I think of it often.
