First time posting. Surprise visit

I was supposed to be out spending the night at a friend's house while my step dad had a party at home. It was around 3am when I decided I couldn't sleep at my friend's so I went home. I unlocked the door and went inside up to my room, I climbed myself into my bed in the dark trying not to wake anyone up. To my surprise there was a body in my bed. I startled myself and went to jump out of bed but the man reached and grabbed me. I said im sorry I didn't know someone was using my bed tonight, he said its ok its just me your uncle. And he pulled me into the bed. He was pretty drunk and im not fully sure if he knew it was me or not. But he started feeling my body, up under my shirt and continued.
