Billy might identify as straight, but his curiosity leads him to explore the gay porn world on Tumblr. He tentatively watches 3D toon gay videos, his eyes widening as he takes in the explicit details. His hand slowly moves to his crotch, feeling the growing bulge. He tentatively strokes himself, his mind filled with images of the gay sex he's watching. He's never kissed a boy, never taken a cock in his mouth, but the thought of it has him harder than he's ever been.
