You've gotta give it to your step mom. She does try. She has booked an entire weekend for a mountain retreat for your family. Your step mom loaded you and your sister up and off you went to the tiny cabin in the woods for a fun family weekend. Everything was fun and games until your sisters phone rang. It was her adviser explaining that she was now on academic probation and would fail if she didn't turn in her term paper on Monday. Your step mom was understanding and took your sister back to town and you and her headed on to your vacation destination. Your dad was going to finish up his day at the office and then head that way. You and your step mom arrive and unpack your bags for the weekend. You have to admit that she looks pretty hot. She is wearing thigh high boots, some type of fishnet lingerie and a flannel dress. Every time she leans over you take the opportunity to take a peek down her blouse. You two are sitting by the fire relaxing when the inevitable happens. Your dad texts her to say that he won't be able to make it. Your step mom rolls her eyes and complains briefly. She then gets a strange look on her face. One you have never seen before. She says that she doesn't want to be bored all weekend and she has something that can keep you both busy. She is acting a little weird and says that before she even tells you her thoughts, that you MUST plan on keeping it between only you and her. She says that you can't even tell your best friend Jake. Her sheer, sexy panties are quickly pulled to the side and she begins to play with her pussy and asks that you store yourself. She knows how good it feels for both of you. She slowly begins to unbutton her cozy flannel dress to expose her big ample breasts. You can't believe that you are actually seeing them! You have tried sneaking a peek for so long now. They are bigger than you imagined and you are embarrassed when your dick pops up and stands to full attention. Your hot step mom teases you by revealing her sexy fishnet lingerie and see through panties. You have never seen a bush like that before. Most of the girls your age are all clean shaven down there. You are so embarrassed because if we are both being honest you could almost blow your load just looking at her. You can't believe this is really happening. She then lies back in front of the fireplace and asks you if you'd like to put your dick in her. Wow ! What a filthy mouth she has ! You have NEVER seen this side of her and didn't imagine she could ever be this way! She is so direct and to the point. Unlike the younger girls your age. she doesn't sugar coat it. She tells you what she wants and how she wants it. She explains that regardless of everything she has taught you, there will be no need for a condom today. She says she wants to feel you skin to skin. She says to pound her pussy hard.even harder before she straddles you and rides your cock to orgasm. She has fucked you like you have never been fucked before and you are at a loss for words. She then says " Let's do this ALL weekend".
