Proxy Paige in Mr. Fitzergood

So I had an issue with my brother and I needed a guys opinion on the situation so I decided to ask my brothers soccer coach. So I let him know that my brother saw me having sex with my girlfriend and he just sat and watched for a bit. Now it’s kinda weird between us. Mr Fitzergood told me it’s cool and that he was just watching because that’s what guys do. As I was explaining what my girlfriend and I were doing when we got caught I saw he was a little excited so I helped him out a little bit!
