The wall's discreet opening promises untold pleasures. A curious tongue darts out, tasting the faint, salty remnants of previous encounters. A thick, veiny cock pushes through, seeking attention. The tongue licks, the lips wrap around the head, sucking gently, as a hand pumps the shaft. The cock grows harder, the breath quickens, and with a final, deep thrust, it pulses, filling the eager mouth with a warm, creamy reward.
