Tell the truth; you saw an opportunity to strip and have some fun at home
From Create Your Own Story
You stand in front of the door with your hands behind your back and one foot coyly rubbing the back of your other leg as you shyly wait for the door to open. The door swings open and your parents are both standing there. Time seems to freeze for a moment as their eyes drop down your body, from your flat boobs to your hairless pussy, making your face blush. You also start to feel funny between your legs, like when you spray the showerhead over it.
"Kiki! What are you doing!?" your mom asks. Your dad remains silent, his gaze fixated between your legs. You move your hand to cover up, but then part of you says not to. That you like people looking. That it feels good to be seen. While your shame urges you to cover up, the new emotions win and you simply rub your hand across your inner thigh before putting it back at your side.
"I thought you would be gone for awhile and it feels so nice to not have any clothes on!" you say in defense.
Your dad looks back up to your eyes and asks, "Why were you in front of the window though? Anyone could have seen you."
You realize you have a couple options. You could lie and say you didn't realize you were in front of it. You could lie and say you don't really care if anyone sees. You could tell the truth, that the thought of being seen was exciting.
