This happened in a bus, at the time I was a student, twentysomething getting my bachelor's. It was pretty late, but the bus was still somewhat full. A few people had to stand, however, toward the back I could see a single empty seat, a group of people my age, probably from the same college, hovered around with no intention of using it for some reason, so I made my way.
There I figured out why. A big fat older guy was using half of it. It wasn't like he cartoonishly used both seats, but enough awkward physical contact was made on my seat claiming process.
My phone was almost out of battery, and with nothing else to occupy my mind, I just started looking around. The fat guy besides me was absent mindedly looking through the window. The college group now standing close to me was made up of an attractive couple and a somewhat ugly guy. They talked about some show I never heard of. Past this group, an older woman sat playing something on her phone, pretty dull fare.
I still remember the most interesting thing at that moment was the way my leg made contact with the guy besides me. He occupied enough space that side contact between our legs was basically unavoidable, it felt pretty solid and warm, not all together a bad sensation.
It was then that something grabbed my attention viciously--the shape between his legs.
These days it's easy to see pretty much anything online, It's easy to just treat everything as mundane after you've seen a picture or video of it, like when you see a picture of a moose. You don't even really process how big those things are until you see one in the flesh and are washed in surprise and awe.
I was having a pretty similar feeling right then toward what I was seeing. Nested between his thick thighs, obscenely marking his jeans, was one of the biggest bulges I had ever seen, you could clearly see a tube shape sneaking its way sideways. I was transfixed for a few seconds. The feeling of his attention turning toward me snapped me out of it. I tried to make it like I was always paying attention to something else, unsure if that had worked, I could feel myself blush.
Only the ugly guy stood next to me now, the couple probably left and I didn't even notice. After a moment I glanced at the big guy again, he was back to admiring the night through the buss window. Here was the first time I actually looked at him, superficially he is not really my type so I had barely paid any attention.
He wasn't particularly good looking, but, dark eyes, a short brown beard and a weirdly shaped nose. Easily over 6 feet tall though, he dwarfed me in my 5'8 pretty hard.
With his attention not on me it was pretty much impossible not to stare again, was it bigger now? The curving shape I could discern alone was already close to 8 inches. When he moved again, I was mindful enough to pretend something elsewhere was way more interesting than his bulge.
A couple minutes passed, the ugly college guy sat across from me now, the buss had emptied a bit. My large target of admiration was covered now, the big guy was somewhat covering it with one of his hands now.
All at once, the awkward but titillating moment shifted into pure discomfort. Was I just staring at a probably straight guy having an involuntary erection? It was probably a good idea to change seats now that I had the option, but right as I was preparing to stand.
