We didn't start this session with the intention of having sex. My sister in law told us that she was going to go take a nap and I wanted to go grab my laptop from my bedroom so that we could watch some shows. My gf came up with me, but I thought it might be fun to give her a little tease. So I pushed her onto the bed and started making out with her and rubbing my hands on her body.

She stopped for a second and then whispered in my ear, "close the door." I got up and closed it and when I came back over to her she said, "I want you so bad right now. You have to put it in me." Now I don't care if a random stranger were to see us or hear us, but I don't want family or friends to see or hear us having sex. So of course I was a little hesitant at first. I told her that she had to be quiet though. She can't moan as much as she usually does. She agreed and then we got straight into it.

I can always tell when she is orgasming because she lets out such a big moan and her body shakes, but watching her body shakes while her hands were covering her mouth was such a hot look. I couldn't contain myself and watching her squirm like that made me cum much sooner that I was expecting to. After watching her orgasm a couple of times, I blew such a big load all over her stomach.

We did our best to stay quiet, and I think we did a pretty good job, but I'm sure we let out some noises here and there. My sister in law never mentioned anything so I can only hope it wasn't noticed haha.

I almost wouldn't even mind having someone watch us now...who knows.
