When I woke Wednesday morning, Jessica was gone and it was 9:30. I found my bedroom empty as well, showered, dressed and headed downstairs. Dad was working and Tommy was reading on the couch. Quietly, he informed me that Jessica had accompanied Jilly to her appointment to have her IUD removed, in case anesthesia were needed, and Angie had gone over to her parents' house to box up more of her belongings that she hadn't had time to pack after Thanksgiving.
He had a grocery shopping list from Mom, so after a quick bite and fixing a travel mug with coffee, we took my car to get the shopping done and stay out of Dad's way at least until lunch time.
"Today is one step closer to getting Jilly pregnant," Tommy said. "Nervous?"
"I'm really not," I answered. "It was an easy decision, once everyone agreed that we wouldn't keep my involvement a secret. Jilly wants a baby who will also represent Mom and Dad's DNA and I can provide that, although not in equal thirds. Unlike your future kids with Jess, this one will be 50% Jilly."
"Because my kids will also have some of Sam's DNA?" Tommy asked.
"25% for each grandparent, on average," I responded.
"You rattle that stuff off so easily. And I thought I was the math geek in this family. But I get lost with all the half-sibling, half-cousin stuff."
"It's basically just figuring out powers of two as fractions, half, quarter, eighth, etc, per generation and each shared ancestor. The difference between full and half is having two common ancestors instead of one. It would be easier to show you the math on paper, though."

Angie, Jessica and Jilly were back by the time Tommy and I finished shopping. Anesthesia had not been needed and Jilly was feeling fine, greeting me with a long kiss and a whispered, "Next week, 'Daddy'."
A chill ran up my spine from being called that.
We put the groceries away, then made and ate lunch, while I showed Tommy the math related to estimating genetic inheritance, which he picked up quickly.
After lunch, Dad resumed work and Jilly left to meet her assistant manager about preparations to open the club the next night.
The other four of us then left to see "The Last Jedi", then in it second week. It didn't reach the high expectations of the franchise's most fervent fans, but those are beginning to feel too lofty for any film to possibly meet, when every casting decision gets criticized as soon as it's announced. Calling the highest grossing movie of 2017 a failure makes no sense, though. As a way to spend two and a half-hours in a theater, I've certainly had far worse experiences, even at movies ranked higher on the highest gross list.

"What are the bed pairings tonight?" I asked, over dinner.
Jilly said, "I'm still bleeding, so I thought I'd go over to my house to get some packing done and then sleep there."
Dad said, "Jess and I will help you, then spend the night, too. Something about wanting to have sex with me in that bedroom at least once before the move."
Angie turned to Mom and said, "It ought to be my turn with Tommy and yours with Derek, but do you maybe feel like a foursome with them instead of being two pairs?"
Mom answered, "That sounds great. I just need to get some of my own packing done first."
Between the four of us, we filled three garment boxes plus two regular boxes of clothes to keep and one for donation, before packing turned into a lingerie show featuring Mom and Angie.
Tommy and I were down to our underwear, lounging on the bed as Mom and Angie kept changing in the walk in closet and coming out in increasingly skimpy outfits to model and tease for us. After a half dozen changes, they stopped at the foot of the bed and began making out with each other.
Whether intentional or not, Mom and I were on the left side of the bed while Tommy and Angie were to my right. So, when he and I crawled to the foot of the bed and stood to join them, I paired with Mom.
She was in a nearly-transparent pink chemise that boosted her breasts into tantalizing cleavage and I buried my face into her boobs, kissing from side to side. Angie was in a black teddy with a plunging neckline and Tommy already had a hand under the right side as he nuzzled her neck.
Mom's hand slipped into the boxer briefs I had on and squeezed my turgid shaft. "Someone's pretty turned on already," she muttered.
"It's hard... not to use the word hard, when I'm near either of you. I've got the sexiest family around, I think."
"You're only related to half of the women," Mom said.
"I meant the seven of us are a single family now. More in the group marriage sense than parents and children, although it's obviously still both."
"A subject for later," Mom responded, as she pushed me back onto the foot of the bed. "Right now, I want to suck on this hard, stiff cock." She slid her way down my body, pulling my briefs off before she got to her knees. Her mouth engulfed me a second later, wet, warm and slithering.
Angie plopped her butt onto the bed beside me, as she pulled Tommy's face between her legs. I turned my head and kissed her, raising my left hand to squeeze her breasts through the teddy's top.
After a short while, I had a flash that Mom's tongue was swirling around my glans in synch with Angie's tongue tangling with mine in my mouth, as if they were one woman loving me with two mouths. Just having that thought produced guilt, like I was treating Angie as an extension of my Mom, but it passed away as the physical sensations returned to being as different as they are. However similar their outward appearances, that's as far as it went. Oversimplified, Mom has always been saltier, while Angie is more sweet. Mom takes charge, Angie goes along more. I loved them both as much for their differences as their similarities.
I realized I was thinking too much and put my focus back on sensation, letting the passion Mom was pouring into me flow into Angie.
Mom sensed I was about to orgasm a second before I did, squeezing the base of my cock to forestall it. She pushed away from my groin, stood up, turned around and backed herself onto my cock, slipping it completely inside her before I really knew it.
She then leaned back, turned her head and took over kissing Angie, while my hands went to Mom's hips and began pushing her away then letting her slip back onto me.
A minute later, Tommy stood and stepped between Angie's thighs as she broke the kiss with Mom to lay back on the bed. He licked his lips and gave me a quick smile as he slowly thrust himself into her warm depths. "So good," he muttered, as he reached under Angie's thighs to lift them, winding up with her knees hooked over his elbows as he thrust harder into her.
Mom faced forward and pushed back at me with her legs, slapping our thighs together as we sped up. One particular thrust caused me to fall back onto the bed and I grabbed Mom's arms to pull her along with me, winding up with her laying atop me, still impaled on my cock. I used my elbows to do a bit of a lobster crawl to get myself more firmly onto the bed, then Mom turned around and moved into cowgirl position. I lifted my feet until I could brace them on the footboard, giving me more leverage to thrust upwards.
Angie reached a hand up to squeeze Mom's left breast, while I squeezed the right. We managed to squeeze Mom's nipples at the same time and Mom let out a deep moan in reaction.
Tommy's thrusts into Angie were making her breasts jiggle on her chest, but I couldn't reach either one. Mom reached a hand over to squeeze each of them, before bracing her hands on my chest. "Oh, fuuuuccccckkkk!" she cried, as I felt her shudder around my cock. "Right there, baby!" I tried not to change a thing that I was doing, but didn't really know what I'd done that was so right. I guessed that I must be hitting her gspot.
As her orgasm intensified, I glanced towards Tommy and spotted the signs that he was close, too. He slammed two more times into Angie before he stiffened and started to cum, just as Angie screamed his name. My body was the last to join in, pumping several streams of my cum into my mother, imagining briefly that I was impregnating her, instead of preparing to do that with Jilly in a short while.
Where had that thought come from? As much as we disregarded the laws when it came to incest, disregarding biology made no sense. Was that what I really wanted, to have a baby with my own mother, DNA be damned? Bonnie had turned out okay, after all.
The train of thought was snuffed out by Mom collapsing on my chest, pressing her boobs into me as her mouth sought out my neck. "That was nice," she whispered in my ear. "You guys should probably go back to your own bedrooms, though. I still have to work tomorrow."

On Thursday night, Angie and I were invited to her parents' house for dinner. Angie said Wendy was going to be there, but Rachel and Bonnie would not.
