Fucking her in front of her parents

My gf and I were on the couch, spooning on her parents couch. We both decided to quietly fuck as her parents were downstairs. So we pulled our pants off and I slowly slid my pulsing cock Into her wet pussy. We fucked slowly as we listened for any noises. Next thing I know, I hear her parents coming up the steps. We both froze. They both came up and sat on the couch and started talking to us. Her parents were extremely religious so this made it more of a scare. Soon they turned and started watching the movie. I didn't know what to do but I was pulsing so hard inside of her. After a few minutes I slowly begin fucking her. Barely moving. Next thing I know, I'm about to cum but I didn't know what to do. I didn't want to make any sudden movements. I stopped moving and tried to stop myself from cumming but I couldn't. I was pulsing and cumming so hard and shooting cum deep inside of her. I squeezed her arm and looked her In the eye, she looked concerned as she could feel me pulsing inside of her. After I came, we laid there for another 10 mins with my cock still inside of her until her parents got up and went to another room. That was the first time I had ever cum inside of her.
