(To change things up, this part is told by Ross. Warning, Ross will have sex with someone else in this part, but it is a one-time thing and was important in his progression; I issue this warning for those who were upset about the twins having sex with other family members.)
I did love Lily, but I knew it was wrong to love her in this way. There was a block, something stopping me from fully involving myself in this affair.
Lily cried out in pleasure as I jabbed my dick in and out of her sex. While we always started with slow gentle thrusts, Lily needed me to thrust faster in order to finish. I had already shot my cum into her, but I refused to leave her unsatisfied. My hips rocked back and forth, and I focused only on her. If I let my mind wander for even a moment, I'd remember I was fucking my sister and stop.
Finally, she let out a final cry. This cry was different than her previous ones, this one was more faint and longer. It meant she had climaxed. At once, I rolled off of her. I stared into her eyes, trying to lose myself, but I couldn't.
"We should get going," I said. "Are you all packed up?"
"Can't we stay another day?" Lily whined.
"No. Vanessa's bringing the kids home today, they start school in a few days."
"Why can't she keep them till school starts?"
I sat up and looked away from her. I knew Lily wasn't a fan of children, and might never want to have any, but Victoria and Ethan were not going to be pushed to the side. I was not going to be that father, the one who chose love over kids.
"I didn't mean it like that," Lily blurted out.
I turned to look at her.
"I only meant that I wish the summer hadn't gone by so quickly, that's all."
"Me too, Lil. But I have to take the kids school shopping, and they need a few days home to adjust before being thrown into their school routine."
"I only meant that Vanessa could take them shopping and give us an extra day or so, but if its best for them to come today, I understand."
"Here's a thought; why don't you take them school shopping," I said. "You should start spending more time with them anyway since we're officially together now."
"I doubt that's the best way to approach this," Lily said.
I sighed and got up. "Fine. Next time just say you don't want to."
Lily jumped up. "That's not what I meant!"
I turned to her, giving her a chance to explain herself.
"The kids don't know about us. If their aunt, who has never shown much of an interest in being involved in their life, suddenly starts doing all these motherly things with them, they'd find it weird, don't you think?"
"Or they'd just be happy you're taking an active role in their life, they are only kids, Lil. I doubt they'd question it."
"Except, they aren't little kids anymore. Victoria is 10 now, she's more than old enough to start noticing things. That's why I told you yesterday we should tell them now."
"Again, I don't think they're old enough."
"Okay, they're your kids. And just to make this clear, I do not have a problem with your children or having them in my life."
I still wasn't fully convinced but I felt a bit of relief hearing her say this.
"I'll take them shopping tomorrow. I used to love back to school shopping when I was a kid, so it'll be fun," Lily said.
"Really? You'll take them?"
"Yes."
The drive home went smoothly, and when we arrived at my mother's house, my children were already there waiting for me. They raced over to me with giant smiles on their faces and tried to push each other away to be the first to hug me. Wrapping my arms around both of them, I planted a kiss on top my daughter's head, and ruffled my son's hair.
Once the commotion died down, I noticed the newest addition to the family; a small bundle wrapped up in a blanket resting in Millie's arms. The other children ran around the living room. Liana and Kyler were arguing over something, the other four and threes and twos were engaged in a game of tag, and the babies were waddling around. Those not old enough to walk, lay in their parents' arms. I walked over to Millie and peered down at the baby.
