I always suspected my brother of taking my panties but it still shocked me when I finally confirmed it. My lace see-through pair with cute little bows, left carelessly on the floor of his bathroom. When I picked it up, it was still wet and smelled like his disgusting cum.

He basically ruined them and I would spend the next few months thinking of a way to get him back.

I got the idea to fuck his friend at a party my brother was hosting at our place. I've always found this guy hot and he always flirted with me, and this night was no exception. The only difference was that this time I was actually going to let him fuck me.

I convinced my bro to let his friend stay the night, because he was too drunk to drive. Then, when everyone else was gone, I french kissed him in front of my brother. Big bro started protesting until I removed my pants. I was wearing the panties he stole from me and when he saw them, he immediately understood what was happening.

His friend played along great. He had a great cock and wasn't nervous about using it, even when my brother was watching. In fact, while I went down on him, he teased my brother about fucking me, reminding him it was something he would never be able to do.

The big dork stayed through the teasing. As embarrassing as it must have been to see his little sister get used like that, his curiosity made him stay and watch.

I gave him my panties back so he could jerk off with him. He looked so pathetic masturbating to us. He was even the first of us to cum, too. His friend and I still had a long way to go. Much later, when we were both exhausted and my tits were covered in cum, I ordered my bro to clean it up.

While he licked the jizz off me, I pet his hair and asked him, "you're never going to steal your little sister's panties again will you?" I let him know that it wasn't just this friend. The rest of his crew, his boss, our neighbors... If he kept misbehaving, everyone will eventually know that he's a sick fuck who gets off to his sis.

Quietly, he nodded that he understood.
