In the dimly lit gloryhole booth, a eager twink kneels, ready to service. A thick, uncut black cock slides through the partition, glistening with pre-cum. He hungrily takes it in, saliva dripping as he works the shaft, feeling it throb and grow harder. The anonymous stranger on the other side groans, fucking his mouth, balls slapping against his chin. The twink jerks himself off, leaking precum, lost in the taboo thrill.
