As dawn breaks, a horny cyclist finds a secluded spot, pulling out a compact, portable ciclotron from their pack. The machine's small size belies its powerful thrusts. They strip off their cycling shorts, revealing a wet, hungry pussy. They position the ciclotron, its arm pressing against their clit. They begin to pedal, the machine's thrusts synchronizing with their movements. Their body rocks with each thrust, their breasts bouncing, nipples hard. The sun rises, casting a warm glow over their sweat-slicked body. They pedal faster, the ciclotron's arm plunging deeper, their moans echoing in the quiet morning air. They climax, their body shuddering, pussy clenching around the ciclotron's arm as they collapse, spent, onto the grass.
