I caught my step-sister fucking my boyfriend and as her punishment, I took her to my friends dungeon, tied her up, suspended her from a hook and whipped her till she begged me to stop! I told her to never fuck him again and that while I still loved her, she would meet an even worse fate if she even thought of his cock again. As you'll see, we did make up with lots of deep kissing and I even kissed her spanked pink nipples and sucked on them to make her feel better. I felt kind of bad so I let her tied me up and spank me but made her promise to never EVER fuck my boyfriend again!!
