You tell him

“Now who exactly are you?” Your brother asks as he lays down next to you on the couch.

You tell him everything. He can’t believe it as you recall the phone call and how you’re so horny you can’t help it. “Are you mad that I let you fuck me bro?”

Your brother is silent for a minute before he speaks saying, “you brought up the sister kink, why?”

You blush and admit, “I’ve always wanted to fuck her.”

“Perfect, I got on good confidence that she’s bisexual. You’re her type in this body. I have a plan. You seduce her, then I come in and you convince her to fuck me with you. Then when you’re back in your body she’ll be a converted, incest loving whore. Thoughts?”

“Sounds perfect! I’ll go into her room to wait. She should be home soon.” Standing up you look back at your brother giving him a wicked smile you flash him your pussy. “We’ll be ready for you” you say with a giggle.

You bound off to your sister’s bedroom to prepare for her arrival. You have no idea where that flash came from. This body is horny as fuck. You secretly love the fact that your brother is staring at your ass as you skip away.
