I have been having an affair with my step sister. I know it’s wrong but we love one another so much. I am 25, she is 21.
Mum and my step-dad went away for the weekend when my girlfriend was at her sister’s party, so my step sister and I were alone in the house.
We had a bottle of wine and watched a movie, snuggled up together on the settee. It felt so comfortable, we turned to each other and kissed to say good night, but the kiss was electric.
