The door creaks open, revealing a shocked onlooker, their eyes widening as they take in the scene. The young man, startled, freezes mid-stroke, his cock glistening with pre-cum. The intruder, instead of turning away in embarrassment, steps closer, their gaze locked onto the young man's throbbing member. The tension in the room is palpable, the air thick with unspoken words and unsated desires. The young man, emboldened by the attention, resumes his stroking, his grip tightening, his pace quickening. The intruder, unable to resist the allure, reaches out, their fingers brushing against the young man's cock, sending a jolt of electricity through him, pushing him over the edge.
