It's all about the size difference! Giant guys, tiny guys, and putting these two extremes together! The "Fun Size" boys are as their name suggest: compact, shorter, smaller, sexy guys. The "King Size" men, tall, huge, hung titans, absolutely love how small those little guys are! They can pick them up, toss them over their shoulder, and manhandle them like toys. The little guys get so excited being next to these giants, standing on their tippy-toes to kiss their tall bodies, wrapped in their big, strong arms, and looking up at them from far below. The stories on FunSizeBoys.com are a real turn-on for fans of gay size difference. The sex is beautifully shot in high definition 4K, incredibly hot, and 100% bareback.
