A young, slim twink, clad only in tight underwear, finds himself in a state of arousal. He tentatively touches himself through the fabric, feeling the growing bulge. With a shy glance around, he slips a hand inside, wrapping his fingers around his hardening cock. He strokes slowly, biting his lip in concentration, his other hand supporting himself against the wall. As his breathing quickens, he pushes his underwear down, exposing his length. He starts to bob his hips, fucking his fist, his eyes closed in pleasure.
