Unseen hands part the gloryhole curtain, revealing eager eyes and a hungry mouth. The initiate, a curious young thing, leans in, tentative yet excited. A thick, veiny cock pushes through the hole, pulsing with anticipation. The newcomer's breath hitches, then they tentatively lick the tip, tasting pre-cum. Confidence grows, and they take the shaft in their hand, stroking it as they take it deep into their mouth, gagging slightly but eager to please. The anonymous cock responds, throbbing and leaking, as the initiate gives their first ever blowjob.
