You wouldn't think that taking a few pictures of your sister would change your whole relationship. But when I got an erection while doing that, it did change our relationship. I expected her to object. She didn't. I expected her to be disgusted. She wasn't. Instead, she decided I'd be her crash test dummy for all the erotic feelings she'd been having and couldn't (wouldn't) do anything about while she was on a date. It was only supposed to be a little exploration. Boy howdy did we explore.
