It was eleven years ago when my Nubile stepmother and daughter started sharing a sexual relationship. It wasn't until that night in early October of my sophomore year that I finally confronted her about the affair, thinking that my insides had been itching just like her panties! She denied all accusations and told me it was either a one night stand or something much more substantial, but when I pressed for details, she said that she and her "boyfriend" had been engaging in a threesome with her daughter and me on a regular basis. This is when I slowly began to get suspicious of her and I could tell from her body language that she was not happy about what was transpiring between her stepson.
