The Ex and I went to a house party one time, she was more into it than usual this time, very excited about going this time. We got there and it started in the backyard, using the pool and having a barbeque there were about 15 couples attending and a few singles. After a few hours of mingling with others, people started heading indoors to cool off and enjoy the basement setup, mattresses and couches and a big screen with porn playing. Everyone was feeling good from the alcohol and weed and clothes started coming off. I head in looking for the Ex and as I get inside stop dead in my tracks. Her and another wife are both naked putting on a sex show for everyone with about 10 people around them, in a 69, putting the video on the TV to shame. Hips were really moving and their moans got everyone else in the mood, I watched as wives started stripping, a few started blowjobs, basically it was turning into an orgy, when the hostess says we need to thank the two ladies for the inspiration and all the men need to take them. For the next few hours, I saw her in all types of combos, MMMFM, MFFM, you name it, she was airtight most of the time. When they were done with her and she was relaxing, she had the biggest smile on her face as she proceeded to finish me off giving me one of her deep throat blowjobs. Later when I asked why she was so turned on all she could say was tonight her slut outcoming. From that point on she was the hit of most parties
