I wouldn't worry about Stifler. Why do you think he had such a limp dick after returning from the outside party? Just because we didn't see it doesn't mean he didn't get fucked. why do you think they changed outfit so many times and left the apartment? The whole evening was exhausting and a seemingly a lot of hard work. It was exhausting to watch and I watched the entire evening. Except for a couple of hours around 11:00 am their time. And before anyone says " you need to get a life", you're correct, but my curiosity got the better of me.
