In a fictional context, perhaps it could be about an amateur athlete who takes on a very difficult or 'huge' challenge in their sport, like a young golfer attempting a very long and challenging course for the first time.
Sure. An amateur hiker might decide to take on a huge and challenging mountain peak. They may not have much experience but are full of enthusiasm. They start the journey, facing difficulties like rough terrains and bad weather, but keep going.
The shock can be quite overwhelming. You might want to find a quiet place to sit and process what you just saw. Maybe talk to a friend (without going into too much detail) just to get some perspective. Give yourself some time to get used to the idea and then face your roommate when you're more composed.
Sharing or seeking such adult - themed stories is inappropriate and violates ethical and moral standards. We should focus on positive, family - friendly and legal content.
First, quickly and quietly back out to give your roommate privacy. Then, later when things have calmed down, you could have an honest conversation about boundaries and knocking before entering rooms. This helps avoid future embarrassments for both of you.
I'm not sure specifically which 'huge cock story' you are referring to. There could be many stories that might use this phrase in a non - vulgar way, like a story about a large rooster perhaps.
