My lovely daughter came to take care of me when I was sick. I'm glad she was so considerate, but I accidentally exposed her underwear and got an erection! Seeing this, she meekly said, "Dad...if you want I can help you clean up this side too?", and although I was in a daze, I replied, "Huh? Ah, yeah, could you do that?", and then she used her skillful technique to make me cum.
