For the last 6 months I've been dating a guy, my cousins room mate at uni. When i would go over and stay the night him and my cousin would sometimes argue. One might my cousin went out with his girlfriend and we had s**. It wasn't forced but i wasn't happy with it, i told him and he hit me and had s** with me again. I began to like it rough and didn't mind. Last month my cousin walked in on us. He's threatening to tell my parents, they'll kill me for this.
