"Oh god, I need all your cum on my face baby brother," I said, rubbing harder on my clit. That seemed to be all the motivation my brother needed. He started to move his hand up and down on his long shaft. I watched him bite his lip and close his eyes as he did. And when he did, oh my God! He sort of changed from my nerdy, but sexy, little brother into an absolute stud. I can't explain, it was just part of that moment. I felt my orgasm building.

But I guess not masturbating for a month and then watching me fuck myself with his tennis racket...
