That would not go unnoticed! I would post a similar pic but would show almost zero buldge wen hard
It does get noticed. I was on the metro last week and this couple were talking with each other. The woman was pressing her thigh right into my dick. And it just kept grinding. I got rock hard but didn't know exactly what to do about it. I have to confess, I was hoping she was telling her boyfriend and they would switch places. They got off first. I got off a couple of stops later. Fortunately things had calm down a little.
