Gave my first bj and swallowed in St. Louis and my wife has no idea

I gave a college kid head in his car while he was visiting home from college. I felt so slutty because I didn’t even know his name but I sucked his cock until he orally creampied me. We just met up in a parking lot and he pulled his cock out and said it’s all yours. I sucked and swallowed and then he zipped up and headed out. I’ve never felt so used and slutty since then.
