I'm actually 16 not 18. My boyfriend rolled me over on my stomach and was having sex with them then pulled out of me and pressed it up against my butthole. I didn't want this and tried to move around and away. He forced it into me and proceeded to have sex in my butt for another 10 minutes or so and then he shuddered, rammed it all the way in me and came. When he pulled out I pooped all over us. He was grossed out, I was embarrassed and I had to clean both of us up, and did my sheets in the laundry finishing re-making the bed as my mom came home from work. The house and especially my room smelled terribly. My boyfriend won't talk to me now.
