It looks very unpleasant - a well-pumped guy is trying his best, and the lady's face is covered with a strange grimace. In general it is not clear - whether she enjoys sex or performs an unpleasant duty! And the body of the lady is not particularly that glitters, and her breasts and nothing at all!
Her sister got hysterical over her boyfriend who drew a slutty picture of her - how skinny and flat she was. Her brother calmed her down and measured her waist and hip size, assuring her that she was awesome! Sure, her gratitude was inadequate - sucking her brother's cock, but didn't the girl deserve sympathy? When she wanted to remove her head already, he wouldn't let her - if she wanted to be a grown-up, then swallow it. And it seemed his sperm was to her liking. Now she could always count on him.
