As I looked down at my pulsing d**k, I sighed unhappily. Now that I was older and "knew better," it was depressing to have such a big fat d**k. The high school girls I dated wouldn't dream of sucking it for me. It was just too much for their little mouths to take. I couldn't imagine it would be any different for my sister. Knowing she loved having a d**k in her mouth, I still couldn't picture her taking my oversized d**k head between her lips.
What I constantly fantasized about was sucking her t**s before I jacked off and shot my c*m all over them. In those fantasies, she always got off on it. Now I felt like that fantasy was shattered. My "innocent" older sister was sexually active, and she would no doubt be repulsed by my d**k the way my last two girlfriends had been.
That didn't stop
