I’m single lady looking for serious relationship

My gf and her mom were home so, dad went on a trip, so she called me home as a friend in front of her mom. We were in the same room at night, we started having sex, I was fucking her very hard and her mom heard her scream very loudly, we dressed up asap and her mom came in. My gf convinced her that she saw a lizard and that scared her, as soon as she left we started again but she came back again, seeing us naked. It was awkward and she just left without saying anything. Now we were shamelessly fucking again, and I left early in the morning before her mom woke up.
