“You know why you can’t fuck me?” “Err, because you’re my sister!” “No, it’s because even if I weren’t, you wouldn’t have the balls!” Every fucking day was like this, and I was sick of it. There she was, parading round the house in next to nothing, fondling herself, stopping me from passing her when our paths crossed in the house. I’d had enough. “Don’t have the balls huh?” I said as I lay on the couch, undoing my belt. She looked on, smirking, until I got on my feet and pulled down my jeans along with my boxers, my big dick flopping out. “These balls?” I asked again as I walked over to her, rapidly tugging my growing shaft. She was lost for words, and while I masturbated in front of her face she snatched my cock off me and started jerking it for herself. I ran my fingers through my sisters hair, encouraging her to put it in her mouth, as soon as she did I grabbed hold of her head and decided how fast it took me. She gagged as I exited her mouth, she put my dick in her hands once more and led me to her room. As soon as the door closed behind us we fucked extremely rough all afternoon. That was the last time she’d ever doubt me. -- source link
