The bus is packed, but these two tanned, straight-looking guys have found a quiet corner. They exchange a secretive smile, their eyes lingering on each other's crotches. The first guy, feeling bold, reaches down and grabs his growing bulge, giving it a squeeze. His companion follows suit, their eyes never leaving each other. The bus jerks to a start, and they use the motion as an excuse to grind against their hands. They're careful, subtle, but the message is clear. They want each other. The first guy's hand slips into his pants, wrapping around his hard cock. His companion does the same, their strokes becoming more urgent. They're taking a risk, but the thrill of potentially getting caught only makes their gay encounter hotter.
