Look at her go, sucking every cock in sight! But when one of the boys grabs on her titties, she turns into a raging ginger whore. She wants to bite his cock off.
I like to believe this has less to do with his cock and more to do with her vagina. Some girls are just extremely sensitive down there, and I think that even a 3 inch pecker such as my own could produce the same results. Don't pity me for having hope.
