I did not know that my son would watch the violin teacher, Jill and me fuck each other. But one day my son asked if he could start lessons. I did not think anything of it. It just meant that he would be cumming four days a week instead of two. So all started out ok. He would teach Billy and then fuck me. Then my son came in one day and put his cock in the teacher while he fucked me. It startled him at first then I noticed how he was enjoying it. When my son finished I watched Joel turn around and began kissing Billy on the mouth. They stood in an embrace.. I was kind of embarrassed. then Billy climbed on the bed with his ass up and Joel climbed up and put his cock in his ass. My son was so happy. My son was sixteen and very nice looking. After Joel left I came back up and laid with my son. He carressed my breast then leaned in and kissed me while his hands worked my pussy. I was riding his hand while our tongues swirled in each other's mouths. Then he got on top and put his cock in me. He had worked me so I was ready to cum so our body's were moving. I creamed his cock as he filled me. I got off and licked him clean. Then he licked me clean. He told me not to worry he liked fucking girls but a cock in his ass is wonderful. He said his dad taught him that one time on a camping trip with his cousins. I guess they fucked each other all night. I asked if his dad fucks him. He said not as often as he would like. I said I would love to watch. he got out some dvd's and so I got to watch my son, my husband and the preacher fucking each other. Now I definitely know that I want to get under those minister's robes.. his cock is long and thick.. I think I need to go and repent... later
