you're hanging out with me (your sister) and at first we are just making small talk but soon i say i need to come clean about something: i saw you in your underwear the other day and i KNOW you're not packing much down there! it's okay though, i think it's adorable! in fact, i've even come up with a nickname for you: BBYDICK! isn't that cute? i'm gonna call you bbydick every time we are alone now that i know your penis so small! in fact, i've seen our other brother in underpants and even he looks bigger than you! isn't that humiliating since you're the oldest brother?? i wonder what other people think in the locker room when they see you! after some teasing, i even convince you to get totally naked so i can see that bbydick! you take it out and i continue to tease you, holding up my pinky next to it & eventually even stroke you with just two fingers! how adorable it is how hard your bbydick gets and how fast just two fingers make you cum!
