~~~~~
I woke to my cellphone alarm at 7:00, with Mom draped over my left side, her breasts warm against my side, her left knee thrown over mine. I would have loved to snuggle with her, all day. Unfortunately, my bladder was calling me to get up. I eased myself free of her and made my way to the hallway bathroom. No sooner was I finished than Mom rushed into the bathroom for the same purpose.
I gave her a quick kiss while she peed. "Good morning, Mom. How can I help today?"
"We showered last night, so how about you run downstairs to start some coffee while I get dressed, then you can come back up. I've got to prepare the stuffing, get the turkey out of the brine, stuffed and in the oven by about 9 AM, then start in on vegetables and side dishes, so we can eat around 2 or 3."
We had just put the turkey into the oven and I was helping Mom with peeling and cutting vegetables, when Dad returned home, with Jilly and Jessica arriving with him. Jilly looked much the same as I remembered, but Jessica had only been 15 when we had last seen each other, having attended different schools in the area. Born just two days after me, we'd felt as close as twins when we were younger. Cute as a teen, she had become a beautiful young woman, sharing her Mom's auburn hair and a physique that vaguely reminded me of Angie's.
Dad seemed unusually quiet as he walked up to Mom and whispered to her. I saw Mom's eyes go wide for a moment, then Dad turned to me and said, "Take a seat, Derek. Something's... ummm... come up."
"Okay..." I said, moving to the living room couch. What was this about?
Jessica plopped into the seat next to me, gave me a quick kiss on the cheek and whispered, "Missed you," then settled back. Jilly sat on the other side of Jessica, also pretty quiet.
Mom and Dad took the love seat adjacent to me, then Dad asked, "Derek, did you do one of those ancestry DNA tests recently?"
I answered, "Yeah, about two months ago. I haven't received the results yet. Angie's dad Jake was adopted, so he knew nothing about his ancestry. As a Father's Day gift, Angie bought a bunch of those tests, got her Dad to take the first one. He's apparently found out who his father is, based on that. She also handed some out to relatives on her mom's side of the family, to establish a baseline for understanding the results. She had one left over and gave it to me the night before I went back to campus and I forgot to take it until the beginning of October."
Jessica turned to me and said, "I'm one of those relatives Angie gave a test, Derek. She and I are second cousins. At least, we're
supposed
to be second cousins. We realized during a class we had together during freshman year of college that my Grandma Hannah Tirman and Angie's maternal grandmother Rose Simpson are sisters. She gave me one of the tests when she started the search for her Dad's relatives. When my results came back, it identified a few relatives but I didn't recognize any of the names, neither did Angie. However, she had the expected matches that should have been our shared relatives, but I wasn't listed among them. I chalked it up to my test being botched somehow and didn't retest."
"What does that have to do with my test?" I asked.
"This morning, I got an email that I had new matches. You are listed as a match, along with one of my mom's cousins, who had done the test independently. You and I have 24.8 percent genetic commonality. That level indicates an aunt, uncle, nephew, niece, double cousin or... half-sibling."
"You... you... think you're my half-sister? How?"
Jessica smiled. "The usual way. Our parents started swapping well before we were born, Derek. I've known about that for a while now."
"I just found out a couple of days ago," I said. "Along with finding out about your mom's club."
Jessica said, "Okay, so both men had sexual contact with both women, so it's possible either of them could be our shared father. Given my lack of matches to Angie's family, I'm thinking it's probably Stan."
I was so shocked, I barely noticed how quiet my parents were being about this news.
Jilly said, "Looking back, your parents were trying to conceive you and I had just stopped taking the pill, but wasn't planning to actively pursue conception until the next month. Stan was taking his condom off to enter Marcy and ejaculate in her, while Sam was using condoms in both of us. Where we possibly screwed up was that Sam wasn't changing condoms after being inside Marcy before entering me, unless he came in it. It would have been possible for Stan's sperm to transfer from Marcy to me on the outside of his condom. At the club now, we have warnings posted next to the condom supplies about using the same condom in consecutive partners, for STD prevention, but enough members opt to take the risk to go bareback that I should probably add a pregnancy warning, too. Just so you know, you and Angie will be considered guests and will need to use them. You need to present a clean STD test to become members."
Jessica nodded, then said, "However the pregnancy happened, the question now is to confirm which man is our shared dad. We need you to log in and see whether the site has any other matches for you that could confirm or deny that."
"Ummm, let me grab my tablet. I have the login info on there." I sprinted up the stairs to my bedroom, feeling my world spinning around again. I pulled my tablet off of the charger and walked back to the living room, quickly seeing an email notification from the testing site that I had matches and logged into it.
"Okay, I'm in," I said, sitting on the couch again. "Ummm, matches. There you are, Jess, 24.8% like you said. I also see one of Dad's cousins, Maria Giambetti, and a couple of her kids. That confirms that I'm a Rosetti, so you must be, too."
Jessica said, "I remember the Giambetti name from my matches, but didn't know who they were."
"Oh, my god, I have a sister!" I pulled Jessica into a hug, which she resisted, for some reason. Puzzled, I pulled away and looked around the room, seeing cautious expressions, when I expected excitement. "Okay, what's up, everyone? I would expect this to be happier news than the faces I'm seeing. Is there another shoe that has yet to drop?"
Jessica took a deep breath. "There is. Last night, my mom and I... we had a threesome with Uncle Stan... with our dad. He committed incest, without knowing it."
I looked my Dad's way and he was avoiding eye contact with me. I shifted my gaze to my Mom, who said, "No secrets
within
the family, baby."
I turned back to Jessica and said, "You aren't alone. I had sex with my mom, after getting home from school two days ago, and again yesterday. I'm going to be the last one to look down on either of you for incest, whether you choose to continue it or not. I hope to continue with my mom."
It was Jessica's turn to be shocked. "What? How?" She turned to Jilly and asked, "Did you know, Mom? You don't look surprised."
Jilly said, "I suspected it when Stan called and said he wanted to come over, without Marcy. I knew six years ago that the reason why they stopped swinging and being my lovers was because of an agreement they made to keep Marcy from seducing her sons once they turned 18. I tried to talk them out of it, to get Stan to accept the incest as moral, so we could continue being lovers. Marcy getting Stan to change his mind would be the number one reason why Stan would come to see me without her, while she was home with Derek alone. But I didn't get a chance to ask Stan about it last night or this morning, because you were right there the whole time."
Jessica asked, "You're okay with incest, Mom? If I wanted to have sex with... my father again? Or Derek? Or with you, for that matter? I can't believe I just said that."
Jilly giggled, taking one of Jessica's hands in hers. "Honey, I'd love that, because I love you. I was so tempted to make a move, last night, but didn't know how you or Stan would react. The idea of incest never bothered me at all, other than the need for it to be a secret, when I prefer to be open in my relationships. But don't ask me if it's okay to have sex with your father again. Ask him."
Jessica looked over at our father, who was still looking down at his hands. "Uncle Stan? Dad? Look at me. Please?"
Dad finally raised his eyes, looking from Jessica to me to Jilly and back to Jessica. Taking a deep breath, he said, "Jess, I love you and your mother every bit as much as I love Marcy and my sons. I tried my best to be your father figure after Sam died, short of divorcing Marcy to marry your mom and become your official stepdad. If I could have married both of them, I would have. You still became my daughter in my heart, maybe my subconscious even recognized the truth. At the same time, I grew up being told repeatedly that incest was wrong. I only stopped being around your mother and you to try and prevent incest between Marcy and the boys. I finally gave in, allowing Marcy to be with Derek two days ago, after his girlfriend Angie came to me to say that Derek was attracted to his mother and I realized I already knew it was true. If not for witnessing them together and beginning to accept it can be a loving act, I doubt I could have made love to you last night, even thinking of you as only my almost-step-daughter. Then I find out this morning that you're my
real
daughter? I'm in shock, frankly, feeling like a total hypocrite."
Mom asked, "What does your heart tell you, Stan? Do you regret loving Jessica physically now? Do you want to continue? You know I'll support whatever you decide."
Dad looked Jilly's way and asked, "Her birth certificate says Sam is her dad, right? Nobody else knows I'm her father?"
Jilly only nodded, but I said, "Dad, just because you haven't taken one of these tests, it doesn't mean that people like the Giambettis couldn't figure out why they match to Jess, especially if they now see me matching to the same degree. It would be even more obvious if someone like your brother Don matched to her as an uncle. You pretty much have to act like Jess being your daughter is public knowledge now and keep the sex the secret, even if it's just a one-time thing. That's the question that's been posed, though. Do you want to continue intimacy with her?"
Jessica slipped off the couch and knelt at Dad's feet, in front of mine. Looking up at him and taking his hands in hers, she said, "Stan, you are the only dad I can remember. I've loved you my whole life and been attracted to you since I knew what that meant. I wanted to have sex with you last night because of that bond, not in spite of it. Please be my lover as often as we can be safe. You can't have sex with me at Mom's club like we talked about last night, but I do want to continue. Please,
daddy
