I love hearing my brother fuck my step-mom in the next room... One day I'll have to join them, but I'm still too shy. In the mean-time, I'll have to make do with jacking to their moans.
My sister wanted to send some nudes to her boyfriend but the only way she can get hard is if she's being fucked in the ass. She usually uses her toys but occasionally she'll ask me to help her out. As a thank you, she always sends me copies of the photos
My sister and I have a mutually beneficial relationship. When our parents are out, I'm allowed to fuck her in the ass, but only if she's allowed to finish on my face. Getting penetrated turns her on so I usually end up with a creamy mouthful of her load.
