There’s a chance my parents heard me sexing my boyfriend in the basement...

So the logic we had was that if we are in the basement, there are 2 floors between my parents and us.. and then we put the TV on to drown more sound out. When we came upstairs after, my stepmom was asleep on the couch in the living room... idk how long she was there or what she heard... but there was only 1 floor between us, and it wasn’t too far from the basement door... this sucks. My parents think I’m a virgin... or maybe they don’t, anymore.
