Kaz was quite nervous not really knowing what to wear and what the party would be like. As we arrived a middle aged guy came out to greet us. He arran...ged the partys and was very likeable and friendly. He got a young guy to carry our bags to our room and invitied us down after we had changed to meet the other couples who were here.Kaz was unsure what to wear so went for a longish summer dress with a low cut front with just two thin straps holding here ample boobs in. As we entered the room. “Can I do it now?” she asked. “I'm really horny and I can't think of anybody better to help me fulfil a fantasy."For the moment, I was absolutely dumbstruck but the spreading warmth in my crotch was taking control of my mouth. “Err, Okay, go for it."Was I really going to be a spectator watching my friend get herself off? She quickly answered that...She stood up and removed her jeans and panties. I had never seen her naked before and seeing her neatly trimmed bush glistening with wetness left me. She then gets all crazy with her tongue. Up and down my cock, around my balls, back and forth across my taint all the while of jacking me off. Making my ass wiggle all over the bed she grabs me by the hips, pulls me to the end of the bed. Spreads my ass wide open and lunges her tongue into my ass hole. FUCK!!!!! I SQUEEL LIKE A LITTLE PIGGLET, I crawled backwards across the bed, up the headboard and stuck to the roof. WHAT THE FUCK!!!She laughs...…….. then says, as there is a 3rd person in the. Painful at first but good, different. And she needed a cum. I started changing condoms and our friend Greg said he had to get going home as his fiance is probably wondering why his dinner went so late. I think we thanked him but I really don't remember as he dressed and left. After I was refitted with a rubber we went back to the standard missionary position and started a nice, medium paced fuck. I told her how much I enjoyed her and how nice she looked and felt under me. It took awhile.
