I can’t believe this happened

So we were just downstairs watching a movie with our parents. I was in a tank top with shorts and nothing underneath. Well my brother and I were on the couch and our parents were in their chairs. We got cold so we just cuddled up in a spoon position and put the blanket over us.

Part way through the movie I could feel my brother poking me. He was in a t-shirt and boxers. It was dark in the living room with only the TV on and the chairs are kind of off to the side facing away from the couch.

He started to play with my boobs over my shirts and I'll be honest, I haven't had a lot of sex so I was just going to enjoy being fondled a bit, even if it was my brother. I reached back and pulled his dick out of the front of his boxers and gently jerked him. Trying not to draw our parents' attention.

By this point he pulled the blanket up and was under my shirt playing with my nipples. Nothing gets me wetter faster. I said fuck it and pulled down my shorts, just enough and got him in my pussy.

We had to go slow but the taboo and the risk made it so hot. When he got close, we didn't want to leave a mess to explain. So even though I'm not on birth control, I just let him finish in me.

We put our clothes back as quickly as we could just before the movie ended. Then we spent about 45 minutes talking with our parents. The whole time I was trying to keep my brother's cum from leaking out.

It was really nice but I still can't believe we just did that.
