Love giving head down on my knees and I swallow. Ask me nicely n politely n next thing you know I am down there sucking all the cum out. Honestly as long as you are not loud obnoxious and/or rude then you will get your dick sucked.
If only all women would understand how gorgeous they look while sucking a cock all the way to the balls, they'll let go of their makeup and would just walk around with their mouth plugged to a cock and jump to the next one as soon as that went limp! What a marvelous world that would be! ;)
