I was spent as Paul climbed into bed with his Dad and my mom. I was slowly realizing what was happening. I had just had the most incredible orgasm in my life, and my mom was in the same motel room in another bed getting fucked as well. Mom and Kevin had stopped long enough to watch me ride Paul until I screamed with orgasmic excitement. Paul didn't cum when I did so mom had invited him to join her and his dad. Mom had been riding Kevin but Paul said he wanted to compare her pussy to mine and had her climb onto her knees so he could doggy style her while Kevin moved into position for a blowjob. I laid on my side as Paul pounded mom's pussy and Kevin did the same to her mouth. Mom's groans were growing louder and faster as both guy's rhythms got faster and harder. Paul bottomed out his cock inside mom and came with a loud announcement, Kevin did the same thing as he emptied his load in mom's mouth. Mom kept Kevin inside her mouth until her orgasm was over. I could see the goose bumps all over her body as all three of them collapsed on the bed. What a night we had as the guys got dressed and said our goodbyes, I was secretly hoping for a repeat the next night.
Mom was getting out the shower as I awoke the next morning and was still naked as I moved beside her at the sink to brush my teeth. As I rinsed my mouth I asked mom if that that was her first time to be with two guys. She told me that after her and Brad had broken up she ran into two guys she went to school with and ended up at one of their house where they both had gang banged her. I remarked that she looked like she enjoyed it and told her tonight was my turn. She asked me if I had ever took a load in my mouth or on my tits, which I hadn't, but that I wanted to. I also confessed to mom that I had watched her and Brad have sex on several occasions. She didn't seem surprised and only asked if I had enjoyed the shows too which I replied of course.
We shopped thru out the day and decided to go to the spa which was inside our hotel. We went for the full treatment which included a mud bath and massage. After leaving the spa we went back to our room to shower and get ready for that night. I told mom it felt like I still had mud in my hair even though we had washed off at the spa, she said the same and suggested we took a shower together so we could get good and clean. I had never took a shower with a girl before much less my mom but I didn't think anything of it and agreed that was a great suggestion. We each took turns washing the others hair and back, it was innocent, as innocent as it could be between a mother and daughter. We turned and faced each other, our breast pushed against each other as we embraced in a hug. Mom pressed her lips softly to mine and told me how much she had enjoyed the weekend. I was taken back by this even after all that I had seen and been a part of the last few months, this was my mom kissing me. Little did I know this wouldn't be our last intimate encounter of the weekend.
Mom had given Kevin her cell number and as we were getting dressed for the evening she received a message telling us to come to their room. Paul answered the door and let us in. There was only one king size bed, but the room had it's own hot tub. Kevin went towards mom but I grabbed him and told him I had first go with him. We all stripped and set in the hot tub for a while. Kevin and I made out as mom and Paul did the same.
