My stepuncle knows that I've been worried about growing up. Becoming a man seems like a huge responsibility, but there's no backing out now. My age caught up to me. He tried to make me feel better about it anyway, so he showed me an old family keepsake box. Things only got weird when I asked him about a jockstrap that was inside. I didn't understand why anyone would want to keep that for so many years. That's when he explained that it was a family heirloom, all about honor, respect, and family values. I didn't know respect meant wearing it as I rode my stepuncle's hard cock! But if this is what will teach me how to be a real man, I'll do anything he wants.
