I came home from college for the weekend and walked straight into the living room. Mom was on the couch, legs spread, her thick futanari cock out and half-hard. She didn't even try to cover it.
"Shit, Mom," I said.
"What the fuck?"
She looked at me and smirked. "Your dad knows. Your brother knows. You're the last one. Come here and touch it."
I should have walked out. Instead I dropped my bag and stepped closer. Her cock twitched when my hand wrapped around it. It was heavy, warm, bigger than any I'd seen. Veins ran along the shaft and the head was already leaking.
"Suck it," she said. "I've been waiting for this."
I got on my knees between her legs. I licked the head first, tasting her pre-cum. It was salty and thick. Then I opened wide and took as much as I could. Mom grabbed my hair and pushed deeper.
"That's it, baby girl. Suck Mommy's cock like a good slut."
I gagged but kept going. She was rock hard now, filling my mouth. My own pussy was soaked. I reached down and rubbed my clit while I bobbed on her dick.
Mom pulled me off after a minute. "Strip. Get on the couch."
I tore my clothes off. She pushed me onto my back, spread my legs, and rubbed her cock against my wet slit. No teasing. She shoved in hard.
"Fuck!" I yelled.
Her cock stretched me open. She started pounding right away, balls slapping my ass. Every thrust hit deep. I clawed at her back.
"Harder, Mom. Fuck your daughter harder."
She did. The couch creaked. Skin slapped skin. Her big tits bounced over me. I came fast, pussy clenching around her cock, but she didn't stop. She flipped me onto my stomach and fucked me from behind, one hand in my hair, the other slapping my ass.
"Take it, you dirty incest whore," she growled. "Mommy's going to fill that tight cunt."
She came with a grunt, pumping thick ropes of cum inside me. It overflowed and ran down my thighs. She stayed buried until she softened a little, then pulled out and fed her cock to my mouth again so I could clean it.
We didn't stop there. She fucked my ass next, slow and deep until I begged for more. Then she had me ride her on the floor, my tits in her face while she sucked my nipples. Cum leaked out of me the whole time.
By the time we finished, the sun was down. Mom kissed me on the mouth, tongue deep, tasting her own cock on me.
"Next time your brother's home," she said, "we're all doing this together."
I smiled against her lips. "Can't wait."
