I asked her if I could watch. Tina suggested a threesome. I asked if I would get to fuck her too. Tina smiled and said that after what Brie had said a...bout my love making skills that she would like to find out for herself just how good I really was. I told Tina that I owed it all to her instructions. She told me to come to her bedroom later after Mom and Dad went to bed. Okay! She also told me that she had to give Brie a pair of panties to wear home since I kept hers. I laughed.At home Mom.

Mom sat me on her bed and then removed her clothes slowly for me so that I could enjoy her show. She removed her blouse but not her bra. She removed her pants and her panties but not her bra. She was saving the best for last. Mom sat on the bed and had me undress for her. I was so turned on that I just stripped as fast as I could. That was not what Mom had in mind but once I was naked there was nothing more to do but get on the bed with Mom.Since she was still.
