Lucas, a lanky twink, is discovered by his roommate playing with Legos, his concentration broken only by the sound of the front door opening. The roommate, a hulking, hairy bear, enters, catching Lucas in a compromising position - on his knees, hands busy, pants tented. The bear smirks, his eyes wandering over Lucas' slender form, taking in the young man's hard-on straining against his jeans. "Looks like you're building more than just toys, aren't ya, Lucas?" he says, his voice a low rumble. Lucas blushes, but his eyes gleam with a newfound curiosity as the bear approaches, his own bulge prominent. The room fills with the sounds of their heavy breathing and the soft clatter of Legos as Lucas eagerly takes the bear's thick cock into his mouth, his earlier innocence replaced by a hungry, new passion.
