"Does mom know you're gay?" My brother said, snickering.
"What, no!" I said. "Ugh, you're so childish." Just then I got up and attacked him. I shoved him against the wall and began rubbing his dick through his pants.
"Woah, hey, what the fuck are you doing?!" He screamed and pushed me away. I screamed as well and pinned him against the wall again.
"Oh my god, I can't stop!" I yelled. I felt his dick begin to harden in my hand. "Nononononooo!"
"Jen," *moan* "stop!" He yelled. "I get it, you're not gay! I get it!"
"I literally ca-" I pressed my lips against his, and wrapped my arms around him. My hands drifted to his ass and I squeezed it. He stopped trying to push me away, his hands fell to his side in defeat. I felt my body changing too, as butterflies appeared in my stomach. My thighs burst out of my jeans, and my breasts grew against my bra until they were over flowing! My nipples began to leak, leaving spots on my shirt. My brother set his hand on my hip. "Oh no!" I thought to myself. My brothers hand drifted up my torso to my back. He unhooked my bra and my tits burst forward. I unbuttoned his pants and pulled them down, taking his full girth in my hands. My brothers hands moved to my tits. As he squeezed, my tits oozed more and more liquid. He pulled out of our kiss.
"Wow... This must be a dream, so I'm gonna go with it." He said.
"This isn't a-" I began, but he pulled me in for another kiss. "Drhmmm! Hmhmmph!" His groping became relentless, from my tits to my ass and back again, he threw off my shirt. I pulled down my panties and shoved him on to the floor. I sat on his dick and began riding him. His face became covered in my breast milk. I pulled my hair behind my ear. "This... isn't... a dream... I was cursed... to have... sex with... whoever I... lied to!"
"Sounds like a dream, feels like a dream." He responded. "I'm gonna...."
"Oh no! Don't cum inside m-" my brother released inside me, filling me with warm goo. My breasts and thighs deflated, leaving me with my original body. I rolled off of my brother and laid there, breathing heavily.
"So when do I wake up?" He said.
"You're not going to. I told you... this isn't a dream."
"You must not be lying... you're not attacking me again... so i just had sex with my real sister?"
"Yeah."
"Oh fuck."
