There is an answer to the eternal question: why do you need a big dick, when you always have a dildo of your favorite size at hand?
I noticed that the little redheaded girl practically does not use her hands when the male is attached to her from behind, she twists her ass and thrusts on the cock with her mouth. If only her tits were bigger, she would have rubbed them yet, but what's available is as it is, and so it will do!
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.
