I was so close to cumming and then she started sucking my cock with all her might. That was it for me. I exploded into my sister’s mouth. Wave after...wave of semen flooding her mouth. But she sucked up every last bit like a hungry dog!“That was incredible .thank you so much. I love you.” I told her. “Haha, you’re welcome little bro. I didn’t know you had such a nice cock. But you need some more practice.”Me: I can practice all I want now, right?Her: That’s rightShe smiled and kissed me again.. Slowly her hand crept closer almost as if on it's own accord.
