My First Time

So I’m 13 and I have a boyfriend so a few days ago his mom gave me ride to their house and, my mom was going to pick me up when she got back home from a doctor appointment. So me and my boyfriend when to the backroom and we were talking and everything was normal and then he kissed me ( I didn’t really think anything of it because we always kiss each other). This is the part where everything goes down hill, so we kept kissing and the he pushes me back and starts to go “downstairs” ( I had a dress on). So I grab his hair and I said stop he kiss me and when down again but this time I let him takeoff my underwear and he ate me out for his first time he was pretty good. So after that we went into his room he got a condom and I’m sure you know were it went from there.
