My mom used to have sex with my stepdad really loudly to piss me off. He was a coward. So I would threaten him, he'd cry, and then she'd get pissed at me. Got molested by my stepmom, pretty sure at the request of my dad, which was fun, so I have a really weird sexual dynamic with them. used to try to be sexual with them as I got older, but all of it stopped around age 10 for me. Glad I got out of that.
