Watching My Brother

This happened yesterday.

I got a really nice sweater for Christmas from my aunt. It came in a really nice bag that had a picture of a really cute guy with no shirt on on one side and a girl standing up naked facing away from the camera. I thought both pictures were really sexy!

I was putting all my presents away from under the tree and realised that I couldn't find the sweater. I looked all over the house and when I went upstairs I could see it lying on my younger (15) brother's bed. I started to walk in and get it when I saw that my brother was laying on the bed completely naked with a pretty hard penis. I had never seen him naked before and certainly not with an erection. He was looking at the picture of the girl on the bag and playing with his penis.

I had never seen a guy do this before so I was very interested. I watched as he rubbed his penis up and down starting slow at first and then getting faster. I noticed as he was doing it his hips started to rock back and forth a little along with his hand. I was so excited seeing him do this that my nipples started to get really hard and I started to get really horny. I had not masturbated in almost two weeks so I was ready!!

As he continued to rub his penis I started to put my hand down the front of my shorts and under my panties. As my fingers slipped through my pubic hair I noticed that I was very wet already and I hadn't even touched myself. I started to rub my vagina with two fingers around and around in a circle. It felt so good I was afraid I was going to fall down.

I noticed that my brother was starting to really stroke his penis very fast and was starting to breathe harder and harder and then all of a sudden his whole body got rigid and out shot a huge glob of semen and then another glob and another until his stomach and his sparse pubic hair were covered with his white semen.

After I saw his penis shoot these long streams of semen I almost immediately began to have an orgasm and it was so intense I couldn't believe it. My whole body shook and quivered for about two minutes. I was just starting to come down from this incredible feeling when I saw my brother get out of his bed, so I quickly ran down the hall to my bedroom. Once I was there I masturbated again and had another incredible orgasm.

Later I went in and took my sweater out of the bag but left the actual bag in his room. I hope that the girl on the bag get's him excited again so I can see him masturbate again!
