Mark is excited.

Mark put the whip down and stepped up behind Julie, reaching around to grab her tits and squeeze them. “So, I get to fuck you however I like now and cum in you.” I heard Julie moan. “And are you stopping birth control?”

Julie turned in his arms, “Yes,” she said.

I was still riding my father’s fat cock but moaned at the exchange nonetheless. “You have no idea how long I’ve wanted to knock you up for,” Mark said. “Now I get to try.”

Julie kissed him, and it seemed sweet and romantic. “Everyone else in the group kissed him,” she said.

Mark smiled, “Yeah, but I have a good feeling.” He put his hands on Julie’s shoulders, and she obediently kneeled and fished his cock out of his pants. As she started to suck on his cock he looked over to me and Dad, “So, when’s Kimmie going to get surgery? I think it’s going to be hot, getting her made into the perfect slut.”

Dad was guiding my motions, holding my waist as I fucked him. “We will need to get agreement from the other members of the group, but it shouldn’t be too long, maybe a month.”

Mark nodded, “I can’t believe how hot it is watching my girlfriend ride her father,” he said. “And I guess that now it’s almost a given that I will propose.” I moaned, and so did Julie. “Though by the time we get married, you will have extra tits and some horns.”

He wrapped his hands in Julie’s hair and pulled her closer, throat fucking her. “I’m looking forward to being able to do this with your horns,” he told me.

I moaned, “So am I,” I said. “On our wedding night, in my wedding dress, face fucking me with my horns.” I shuddered on top of dad and he groaned, he was lasting a while, but I assumed that was because he had already cum a couple of times today.

Mark laughed, “God, this is going to be fun.” He pulled Julie back from his cock and took a seat beside my father. Julie quickly settled into his lap, facing him as I watched his cock sink into her black cunt.

“So,” Mark said with a grin, “seeing as I am going to be proposing to your daughter, should I start calling you Dad?” he asked.

I couldn’t help but laugh as the stupidity of all this, my father was fucking my, my boyfriend was fucking my best friend. I was going to get modified to be the perfect slut for my family’s incestuous **** ring, and here Mark was asking if he could start calling my father dad.

Dad didn’t respond. He reached around me and grabbed my tits. “I’m looking forward to you getting your extra tits Kimmie.”

I moaned, feeling myself close to cumming again.

“Julie,” Mark moaned, “I think your cunt feels even better knowing you aren’t on the pill anymore.”

Julie moaned, “God, I can’t believe I agreed to this, but just watching Kimmie be used made me so hot.” She moaned as Mark sucked on one of her nipples.

“So, Mark,” Dad said. “If Julie signs a full contract, what would you like to do to her?”
