As the bus roars by, the teens inside are oblivious to the world outside, lost in their own little universe of flesh and desire. The blonde's juices coat the boy's cock as she grinds on him, her hips moving in a rhythm that's both natural and new. He thrusts upward, meeting her rhythm, his fingers digging into her hips. The cash, forgotten, scatters as they move, a reminder of their transaction, but it's the raw, teenage lust that's truly driving them now. They switch positions, the boy on top, his body tensing as he fights to hold back. The girl takes control, pushing him to the edge, and then, with a final thrust, she sends them both tumbling over.
