It was getting hard and and I was biting it lightly now. I removed the boxers and started taking the monster inside my mouth it tasted of pee and pre ...cum, salty and gave him a deep blow job but he didn’t come yet.He took of my net boxers and started licking my balls and the area below. And that he started riming me. He rubbed my ass and the ass hole with lots of lube and started licking it. He was tongue fucking me. It felt really awesome. He made me stand on the floor and he stood behind me.. He agreed. ‘Ok, let’s get our showers so we can get on the road.’ My shower didn’t take long. Since I would be sitting on my sons lap for five hours, I wanted to wear something real comfortable. My jeans would be too tight. Plus it was too hot to wear them. I looked in my closet. As I was going though my clothes I found a summer dress I brought. It was the short type with sleeveless arms. It buttoned up in the front. I unbuttoned it and put it on. When I finished buttoning it up, I noticed it. “mom what are you doing?!?!”Lindsey exclaimed shocked that her mother would actually touch the big thing between his legs. But also very curious about it as well. “Lindsey sweet heart, boys like being touched this way. come closer and try” Lindsey wasn’t sure, but she trusted her mother so she quickly moved to the bed, and got down on her knees to give her brother’s manhood a closer inspection.“it’s so big!” Lindsey exclaimed quietly.“it will get bigger as he gets older too” Kathryn stated. I reproduced the effort of swaying back and forth like I had been while pulling my drunk hubby and my breasts were slapping each other silly back and forth. What’s more depending on the angle of the mirror it was entirely possible that my son may have actually seen some hair sticking out down there. I had not yet developed my middle age paunch that would have hidden my triangle of hair from that angle.At first my stomach did flips, I could not believe that I had so carelessly exposed myself to.
