Summary to date:
Philip and Serena have fallen in love within the crucible atmosphere of an intensive training session, in Princeton, NJ, that their company runs. Philip visits an old flame, Mandy, in New York, while Serena is off with Steve, her lover, who predates her affair with Philip. Mandy decides to come to Princeton (from New York) to check out her competition, and Philip tells Serena that Mandy is his sister, so she won't suspect their relationship. That doesn't work, and Serena invites her brother, with whom she has long been incestuous, to come up from Philadelphia, where he's been working recently. It's a dangerous situation as we rejoin the goings on.
***********
This is the conclusion of the story of Serena and Mandy (and Clark and Philip, with complications like Steve and Old Man Potter)
************
Serena's brother Clark arrived first, at 10AM. Serena and I were both in our Training Session, but luckily it was a half day. When Serena got the text that her brother Clark had arrived, she told Professor Taylor she had a migraine headache, and could she please be excused? She had to go lie down to let it pass. As she left I handed her a note. It said,
Don't you dare have sex with Clark while I'm stuck here in this bleeping class
I heard Serena suppress a giggle as she left the room. She headed to her own apartment.
A half hour later I got the analogous text, mine of course from Mandy. I texted back that I was in class until 1PM, but to let herself into my apartment if she liked. I told her I had left the front door unlocked. She texted back thanks.
When I got home Mandy attacked me with some ferocity, and it was all I could do to keep her from having sex with me. She had washed the dishes, made my bed, vacuumed the floors, and was washing the windows when I entered. I could hear the washing machine enter its rinse cycle. The dishwasher was working, too.
"We're not married, you know. You don't have to play the domestic role," I said. "You do, however, play it amazingly well."
"How can you live like this? I found these in your unmade bed. Are you wearing panties, now? Cross dressing? Kinky, Philip," Mandy said, as she brandished a pair of Serena's panties, dangling from a finger. Seeing my face, she said, "Hey, I don't judge. Whatever floats your boat."
"Why did you have me tell Serena that you're my sister?" I asked.
"She won't get so jealous, that way. Besides ...wait a minute. You don't know??" Mandy said.
"Know what?" I was not having a good feeling about this; there was something in Mandy's tone of voice.
"Your Dad never told you?" Mandy asked, her voice full of incredulity. Now I was truly flummoxed.
"My Dad told me lots of stuff. He drilled me on 2+2=4, for example. He taught me to ride a bicycle and to drive a car. What are you getting at? Spit it out, Mandy!"
"You actually
are
my brother. We've been having incest," Mandy said, smiling broadly. "And to think, you didn't even know!"
"What in the world are you talking about? Are you drunk or something? You're speaking nonsense," I said.
"How shall I put this? Your Dad is your Dad, but your mother is my mother. My Dad is your Dad, but my mother is my mother. We have the same two parents, biologically speaking. You didn't know?" Mandy said.
"What have you been smoking?" I asked.
"It's true. Our bio parents had two kids, you and me, and then decided they couldn't stand each other. They both remarried, to the people they were each cheating with. One of the newly formed couples got you, and the other new couple got lucky, and got me. Simple, right? I can't believe nobody ever told you!" Mandy said. "You were three, and I was only one year old at the time."
"Are you serious? You're my full-blooded sister? Really? I don't believe it!" I said. I was staggering. "My Mom is not actually my Mom? How can that be?" Mandy told me later that the blood drained from my face and that I was as white as a sheet.
Mandy took out her phone. She called her Mom. "Philip doesn't know. You know what, c'mon, don't be dense. Tell him," I heard her say on the phone. Mandy handed me the phone, a triumphant smile on her face.
Mandy's Mom said hi, and we exchanged banalities. Then I heard her take a deep breath and she told me she was actually my own Mom, too. She apologized for never having told me. I gave the phone back to Mandy and sat down heavily on the cheap couch in my apartment. I was stunned, and couldn't speak.
"I'm in love with my sister. I've been fucking my sister. We're incestuous. Scotch whisky is in the cabinet over the fridge. Get me some, will you?" I was in shock. I was fighting off a panic attack. Mandy had known all the time. She had known we were siblings when I first seduced her. She had known when we first fucked, and she fell in love with me, and she let me fall in love with her, anyway.
She knew and - apparently - she didn't care. Maybe she even liked the idea? Could she be that strange? Could I? I always knew I had a kinky side; Mandy knew it too, of course. Fully aware incest, as opposed to unwitting incest, however, was over the top kinky. What was I supposed to do about this?
Mandy brought me a hefty glass of Scotch, since she realized I was in shock. I had taken one sip of the healing, amber liquid, when Serena and Clark walked in. Serena looked ravishingly beautiful and sexy like she always did; I'm sure Mandy was intimidated. However, her brother Clark made Brad Pitt look ugly by comparison. They made a fabulous couple. Too bad they were siblings, right?
Just like Mandy and me, I thought, and I felt sick to my stomach.
"That looks good," Serena said. "What are you drinking? Getting a head start, are you?"
Serena had that freshly fucked look she gets after we do the deed. I knew it all too well. I felt like throwing her words right back at her, but I was in no shape for clever repartee. I was barely able to function.
So, Serena had just fucked her brother. What else is new? I'd been too busy learning of my incest, with my very own bleeping sister(!), than to have fucked her. Well, the night was still young. Would I even be able to get it up, knowing now that she was my sister?
I looked at Mandy, scanning her luscious body from head to toe. I had enjoyed her body over the years more than I could say. I remembered the first time I had laid her, the first time we had made love; how vulnerable she had looked, how her body had responded to my every touch, and when I entered her...
