My sister is 5 years older than me, so when her friends came round i got my first bonners to a few of them. One of them was my favourite, we once went swimming with her and I remember loving her body, me as a 13 yo boy. Fast forward to me at 25 and her 30, she's divorced and getting over shit. She moves in with my brother (as a house mate) and I start to get to know her again. I know my sister wouldn't allow us to get together so I just played it safe and kept the flirt to a minimum. Until one party, very drunk I ended up in the toilet with my cock in her mouth! She made me cum and she swallowed it.... she quickly left the bathroom so no one saw us together....but then someone saw us kissing and all hell broke lose. The dust finally settled and we all went back to our normal lives... until the next party. She was there and we decided to do it again, only this time we needed to fuck. We slipped out of the party and rushed back to hers. My brother was out, so we fucked loud and hard, we loved it and I came deep inside her...like a dream. Then....he came home. He couldn't find out. Luckily she had a ground floor bedroom. So she went to chat to him while I jumped out of the window and ran home. We snuck around for a while after that, fucking a lot, but eventually it fizzled out. It was so exciting, this older woman who I'd wanted for so long and it was forbidden!
