I was 15 at the time and bi but  still interested in girls. My brother, who was 18, had just gotten home  from school and was still in his baseball uniform. My dad was at work  and my mom was out of town so it was just the two of us. We both needed a  shower so I told my brother to get in first and I would take a shower  after he was finished.
I  heard the water turn on when I realized I had left my cell phone in the  bathroom. So I knocked on the door and my brother opened it. Her was  standing ther in just his jockstrap with his cup still on. My brother  was about 6 foot 2 inches with dark hair and rather skinny. I on the  other hand had blonde hair and was only 5 foot 6 inches with a muscular  build. I was a freshman football player.
When  my brother opened the door he just kept getting ready to get in the  shower. Well I was not brazed a bit because we were pretty close. We  would play around slapping butts and wrestle and I was just getting to  the point that I could pin him. So I went in the bathroom to get my  phone and he dropped his jock strap well I had just remembered that my  mom had wanted me to ask my brother if he could pick my sister up from  her friends house that night. So I asked him and we started talking  about baseball and other sports.
He  was in the shower but had it cracked so he could here me well our  shower was a big one with a seat. I had to pee so I went to the toilet  and dropped my shorts to pee. Well my brother asked my about girls all  the time but this time he asked my how big I was. Well I was about 6  inches erect. I asked him how big he was and he was about 7 and a half  inches erect. We were just joking around about that when I got a txt  from my sister that said we had to pick her up in 20 minutes.
Well  my brother was in the middle of washing himself so I just decided to  get in the shower so we could still pick my sister up and I would be  clean. My brother didn’t mind a bit. I was cleaning my self when my  brother started to get hard. Well I started to laugh at him so he  grabbed my balls. We started play wrestling in the shower when I started  to get hard for my brother. I had never realized how hot he was.
He  saw my erection and asked if he could give me a hand job. I said sure  and he started rubbing me I was so horny that I just grabbed his ass and  starting eating. We got out of the shower and went into my room and he  gave a blow job. He was amazing at it and I started to cum right away. I  asked him if I could fuck him and he was over joyed. So I but my 6in  cock into his tight hole and it just slid in it amazingly well. We had  so much fun that day.
