Jane is your girlfriend. The two of you have been dating for 6 years. You invited her over for dinner to your house to meet your family.

She asked you if she can stay the night and you agreed. You then saw her wink at your brother but you just brushed it off.

Everyone sat at the dinner table, waiting for the food to be served while Jane is busy talking to your brother.

You dropped your fork so you went under the table to pick it up, only to see your brother's hand caressing Jane's thigh.
