I lowered my head and sucked my sister’s tits into my mouth one at a time. Sweat from riding my cock had dampened my sister’s skin, and I sucked her nipples like a child in need of comfort.
Trust her, I told myself. Trust your sister.
“I’ll let you fuck Mom and the other Moms,” Diana panted, “if you don’t get mad when I tell you who I want to fuck.”
I growled and lifted my sister as I stood. I bounced her on my cock, her wet pussy slipping and sliding from my knob down to my balls. Her golden hair flew about, wild and free, and her moans filled the room as louder than they ever had before. My balls spanked the bottom of her ass, and my cock sloshed through her wetness, her cum-slippery hole sending rockets of pleasure through my cock.
“Who?” I growled.
Diana laughed.
“Who?”
“Lana,” Diana cried out as I went deep. Her pussy clenched my cock hard then, her cream flowed, and her muscles tensed. My sister was about to come. “And you–in the ass.”
My balls tightened, and I came, the surprise shocking me as I filled my sister’s cunny with cum. She whimpered as I held her tight against me, as my entire body spasmed in one intense shockwave. Diana’s relaxed as I spurted my jizz into her, and then I sat on the bed, driving my prick further into her muff.
“Ooh,” Diana moaned. “Your cock hits deep.”
“Sorry,” I said, shaking my head. “I didn’t mean to come.”
“Bad fucking brother,” Diana whispered in my ear. She grabbed a handful of my hair and squeezed, pulling my head back as she did. “You only get to come first when I let you come first.” She grazed her teeth across my chin. “I’ve been too nice to you lately. I’ve been letting you punish me. I’ve been letting you force me to fuck.” She bit down hard on my chin, hard enough to make me wince. The slight pain felt so fucking good that my cock twitched. “I’m going to punish you now because you’ve forgotten who’s in charge.”
And punish me she did.
Timmy out.
