Nicely written story, good build up wonderful ending brother and sister shareing their love with another.
My sister - two years older than me - loved cock (she's middle aged now and not as highly sexed these days presumably), and so did I... I still do. She caught me masturbating to a gay porn mag one day. She was shocked that I had closet gay tendencies (she didn't tell anyone, and never has), and she was amazed at the size of my cock. So for a couple of years if ever the two of us were alone we "messed around". She loved sucking me off and being fucked up the bum (even though I was and am mostly a bottom); I never fucked her cunt - she wanted me to - and I never went down on her. Wished we could've had a threesome with another guy but we both thought it might freak a guy out, and we didn't want our secret getting out.
