My father caught me watching porn. It was a transexual film, with a cute woman with a big dick.

"You like girls with huge dicks?" my dad asked.

"Uhm, yes," I said, blushing.

"Then why not me?" he asked. He unzipped his pants and showed me his large member.

"I have a big fat dick," he said. "I could be a girl for you."

"Dad," I said, "you're my dad!"

He pulled out his cock and pointed it at me.

"Lick it," he said.

"No way! You're my dad!" I protested again.

"I've seen what you write online. You want your dad's big girl dick." My dad slowly stroked himself in front of me while looking into my eyes.

"Yes," I confessed. "But it's incest..."

"That's the point," he said. "Why shouldn't we do this? We're both adults. And if it feels good, then it is good."

"Dad..." I didn't know what to say.

"Look how hard my cock gets when I think about being a girl. Do you want that feeling too?"

"Yes... oh god yes!"

"Tell me," he ordered.

"I want to be a lesbian with my dad," I said, as I looked at his hard dick and stroked mine.

"That's right," he said. "Now come here. I'll make us both happy."

My dad grabbed me by the hand and led me to his room. He pushed me onto the bed and got on top of me. His cock was so big and thick that I felt overwhelmed just from getting fucked by him.

"Oh yeah, suck my cock," he told me.

I wrapped my lips around his shaft and started sucking. I'd never done anything like that before. But I loved having my mouth full of his dick. As soon as I had taken all of it down my throat, he shoved his whole length into me.

"Fuck, I'm going to cum..." he moaned.

"Cum inside me," I begged. "Please, please fill me up."

"Oh fuck," my dad groaned. He shot load after load into me.

When he finished, he collapsed next to me and fell asleep. My own cock was rock hard, however, so I decided to fuck his mouth while he slept. When I came, I filled his mouth with my sperm.

The next day, my dad tried to pretend nothing had happened. But when I masturbated in front of him and asked him if he wanted some, he said "yes."

We've been fucking ever since.
