Allen is your boyfriend. The two of you have been dating for 9 months. You invited him to your house to meet your family.*

He asked if he can stay the night and you agreed, you then saw him wink at your sister but you just brushed it off

Everyone sat at the dinner table waiting for the food to cook while Allen was busy talking to your sister

You dropped your fork so you went under the table to pick it up only to see Allen's hand carresesing your sister's thigh.
