First sex expiarance

My first expierance was with my brother I was 12 we started playing cards in a barn it was strip poker my brothers penis was a little bit bigger than mine.we just used to wank each other to start with then it went onto sucking each other off.
This all happened over a 8 month period.
We used to share a caravan our parents used to do bed and breakfast so the van was well away from the house.
One night I was woke up with his penis in my mouth it was great then after a bit when we had been wanking and sucking he tried fucking my arse it was very tight I thought I was going to birst but it did feel good its well worth trying.
