It's summer on the London Underground, and it feels like there is no air left in the train cabin. There is also no space. Part of that is my fault. I am visibly taking up two seats. But I'm not rude, I'm just physically huge.
Each of my thighs, barely held in by 4XL denim shorts, takes up an entire seat. The sweaty meat of each quadricep, spreading as thighs do when sitting down, strains against the thick denim of the shorts. Trickles of sweat are threading between my coarse, dark leg hair, wetting the edges of the shorts. You are watching a droplet now, work its way down the inside of my thigh, fall and lightly splash on the train seat. I am watching you watching, though you haven't realized it yet.
I take a deep breath, though it feels like there isn't enough air in this entire train for me. The breath lifts my thick, muscled chest into the air, pulling my back up straight and making me, for a second, even larger. Everyone else plays the game that you're supposed to play: sneaking quick glances at the muscled giant, trying to figure out if I am 7 foot or 8 foot, pretending they were looking at the advert behind me. When my chest inflates, their interest increases in the advert. Predictably. You are still looking at little beads of sweat spring from the dark twists of hair poking from my too-tight shorts. I catch you licking your lips.
I'll play a different game with you.
I drop my hand to my crotch, feel the slight damp of my own sweat. Looking elsewhere, I idly thumb my package, rubbing a thick, calloused thumb over my bulge, tracing its contours. I keep rubbing, very slowly, for about half a minute. Just enough so that my cock starts thickening. The strain on my shorts gets more intense, and anyone looking can now see a drumbeat pulse at my crotch. My thighs feel like they are beating too, swollen with blood from a tough workout, desperately wanting to be free of the choking denim.
You're still watching. As my finger glides over the swelling in my pants, I see something similar happen to you. Similar, but not at all the same. A small lump appears in the front of your pants, that you easily hide with your hands. I'm a mountain next to your molehole. I drop my massive, barbell-hardened hand over the mound of my bulge, just to show you how little it covers.
