HUNTB-690 — My Younger Sister, Who Is In The Midst Of Puberty And Wants To Act Grown Up, Saw Me Masturbating And When I Hurriedly Hid It, She Said, "I Know That Much Too! Shall I Do It For You?"

My sister saw me masturbating and when I hurriedly hid it, she said, "I know that much too! Shall I do it for you?" ... She made a surprising suggestion! I ejaculated within seconds after she gave me a handjob! However, my sister was wondering why my dick didn't go down even after ejaculation, so I made a desperate excuse saying, "It won't go down just because I came from a handjob like that," and then she took my dick in her mouth. As expected, I ejaculated with a blowjob. This time, my sister's expression changed! ? "I have to go all the way..." I crossed the forbidden line.
