Sibling Rivalries

Have been thinking a lot lately.... I don't think there would be many around that can say that they have shared siblings like I have been... Sure some have had sisters, even mother and daughter.... But what about brother and sister??? One of my good male friends, a real ladies man. Shocked me suddenly by turning all gay and bi on me on a night out.... Since then, he has been jacking me off, sucking my cock, and taking it in he's ass raw. We've had about a dozen rounds so far.... And he loves it... Perhaps to much ;)
Recently.... I have started a fling with he blonde sister. Sexy... Gorgeous.... And a dirty bitch in bed.... Its great.... Just like her brother.... She loves giving head and taking it in her ass.....
He knows about me and her but she doesn't know about him and me... Its a great turn on for me.... And he loves it even more.... Strange??? But good....
Just thought I'd share.....
