I almost made it out the door on my way to the party but my son, Chris , stopped me. I quickly told him that the babysitter was in the other room and would heat up some mac and cheese for him when he was hungry but he wanted to talk. And as LOTS of questions. What is this bulge in my pants? Should I touch it ? Why do you have a collar and a leash around your neck. I reluctantly opened my large jacket and told him that this was no ordinary party but my weekly Orgy. In my open bra and crotchless panties I sat on his bed and talked to him about his erection and his first ejaculation. I dumped the bag of toys that I was carrying on his bed to show him each one and explain the types of filthy things his mommy does at an orgy. the more I sat there and talked to him the larger his erection grew. I have been waiting for the day that would come soon that he could come along with me to my sex parties. One thing at a time I told him and showed him how wet his erection was making my puissy. I told him to slow down when he felt like he was about to cum and run his thumb across the head when he was ready to explode. I told him to wait until i was ready for him to cum. When I was ready and  knew he could not stand it any longer I put my face and open mouth close to the tip of his penis and let him cum for the first time all over mommy's mouth and face.I was so proud of him! His first initiation into puberty.!!
