You'll be staying at your girlfriends mother's house for a few weeks and meeting her for the first time. Your girlfriend has told you all kinds of wild things about her being into a "free use" lifestyle and you are excited to see if it's true. Upon arrival she greets you and can't stop gushing about how cute you are. She mentions being free use multiple times and offers for you to use her right then, but your girlfriend tells her to lay off. Despite your girlfriends warning she continues to flirt, stroke your big dick and jiggle her plump ass in your face. The next morning she wakes you up in bed next to your girlfriend, wearing only a sheer robe. She's stroking your big dick again and asking if you want to take her up on her offer. You can't resist so she begins fucking you right there. Her warm tight MILF pussy drive you wild as she talks dirty and you two fuck in multiple positions. Once you are both ready to cum she begs you to cum inside her pussy raw while in missionary, talking dirty and encouraging you to fuck her deep and unload your balls inside her.
