i was drinking with my dad on his birthday and i asked him what was one thing hes always wanted to do or have. He moved close to and smiled at me before running his hand up the front of my dress and stopping just on top on my panties. I tried to push his hand away and he told me to be still that he was trying to show him the one thing he always wanted to have sex with me. i stood up and tried to get away from him but he pulled me to him and kissed me on the lips while playing with my ass. he just laughed and told me to calm down that it's not gonna happen that hes just messing with me, but i felt like he wasnt that he really was gonna force me. idk what stopped him but im so scared of him now i get really nervous when im alone with him. what should i do?
