In the dimly lit, anonymous booth, a mysterious figure awaits. The door slides open, revealing a tantalizing glimpse of the unknown. A gasp echoes as a massive, veiny cock appears, throbbing with anticipation. The initiate, unseen, takes a deep breath and tentatively extends their tongue, tasting the salty pre-cum. Encouraged, they take the entire length, gagging slightly, then finding a rhythm. The cock pulses, ready to burst, but the initiate shows no mercy, eager to prove their worth in this taboo initiation.
