I don't understand why though? Who cares if someone thinks your girlfriend is hot and knocks one out to her picture. It should be flattering to you that your girlfriend is desired to others. It's not like you will ever KNOW if someone did jack off to her picture, and even if they told you, you wouldn't believe 'em anyway.
I'm proud of my girl, so i asked her and put her on here but you guys deserve to see the most beautiful girl ever created. Well, I can't NOT be biassed can I?
