I'm still reeling from my recent breakup, and I confide in my sister about the whole ordeal. She listens with a mix of sympathy and "I told you so," reminding me of the time I ditched my ex at the movies. But when I reveal that my ex claimed I had a small dick, my sister can't resist teasing me about it. She even offers to judge for herself, and I take her up on the offer. As soon as I reveal my cock, her teasing turns to shock, and then to lust. It's clear I don't have a small dick, and my sister can't get enough of it. She forgets that it's her brother's cock she's playing with, and I'm left wondering how things escalated so quickly.
