Is it normal that my dad lied about having sex with my bff's mom?
So last night I'm in the the living room and I hear a bed shaking down the hall. So I go down the hall and listen up against the door. The next thing I hear is really ruff and low and moaning. I cracked the Door to see if my dad and my friends mom having sex. I peeked and saw my dad dick and her pussy. So today I asked my dad if they had sex. My dad denied it. But the thing is I have proof. Is the normal the her denied it?
