The rest of the week was an emotional blur. I hung around Mom like a puppy, with it getting to the point that she had to jerk my leash.
"Stop it, Kevin. You're acting like a lovesick fool, and if you think your father and sister aren't going to notice, you'd better think again. I've already seen Jan looking at me strangely. Act normal, Son. We'll have our time together."
Then there was Jan. She stayed turned on. I couldn't satisfy her. Every night she would sneak into my room. We'd whisper, listen to Mom and Dad, and then succumb to our own urges.
I don't remember ever hearing Mom and Dad go at it before, when Jan and I were teenagers, but they were sure going at it now. It seemed that almost every night the bedsprings would be squeaking.
I couldn't decide if Jan was going for Mom or Dad, or both. She had become very affectionate with both of them. One night instead of sitting on the couch with Mom and me, Jan playfully climbed into Dad's lap to watch our programs. I was watching, as was Mom, as we held hands under the throw. Jan leaned down and whispered something into Dad's ear, then they both laughed and she wriggled her butt on him. To me, it spoke volumes, but until the next day I didn't know if Mom noticed.
As we sat in the kitchen drinking coffee, Mom asked, "Have you noticed Jan acting a little strangely lately?"
I almost choked on my coffee, because only a couple of hours before I had my dick buried to the hilt in Jan's pussy. "She's always strange, isn't she?"
"You know what I mean. Did you see her last night on your Dad's lap? If I didn't know better, I'd think she was trying to get him interested. You don't think so, do you?"
I stood up and walked behind her, bending down to kiss her neck while I cupped her breast. "Would it be so bad? I mean, look at us."
Mom gave a throaty laugh. "I guess not. They're both adults. I've just always wondered about Jan. Sometimes she sends off sexual vibes that she doesn't seem to care in which direction they go. You know what I mean?"
I cleared my throat. This was an opening I had hoped for, but I had to tread carefully. I didn't want to get Jan in trouble or compromise her with Mom. How do you tell your Mom that her daughter wants to jump her bones? "Jan is a very sexual woman, Mom. Surely you must know that. She's your daughter, and you're the most sexual person I know."
"I guess so," Mom laughed. "I remember when I was her age."
I spoke a little hesitantly. "I hope I'm not compromising a confidence, so don't let her know I told you this."
"What?"
"Jan told me once that she loved beautiful men and she loved beautiful women. She said we shouldn't be so quick to label people."
I expected Mom to gasp or cry or something, but she didn't. She mused, "I thought so. I don't care, you know. I just want you kids to be happy. My thinking has always been that love is such a precious thing, that we should celebrate it wherever we find it. Who cares if it's a man or woman, as long as there's love?"
Wow. Mom was much more open than I expected, so I thought I'd ramp it up a notch. "She's always thought you were beautiful, Mom. Who knows? Maybe she's going after you and Dad, both." I laughed when I said that, to take the edge off a little. I feared I might be walking too close to the edge, but Mom and I had had some pretty deep discussions lately.
She laughed and pushed me away. "Oh, get on, you. God, now you're telling me I have both my children after me?"
"I'm just saying."
I sat back down and Mom continued. "I don't think so. Maybe your Dad, but I don't know. It's different between daughters and fathers, and mothers and sons, you know. It's the power differential. Society frowns on daughter-father sex and, when the children are young, well it should. That's just wrong. But consenting adults? That's an issue to be debated for centuries, I guess."
I nodded. I knew exactly what she was saying. I couldn't imagine any man feeling victimized if he made love to his Mother, but we were always reading about women who felt victimized by their Dads. Kind of like the female teachers in the news for sleeping with young men in their class. As long as they're over 18, who cares? Plus, every man who read such an article thought, "I wish we had teachers like that when I was younger." But reverse the scenario and make it a male teacher with a female student and, even if she was over 18, the response was, "Yuck."
"Besides," Mom said. "I can't see your father doing that. He's pretty strait-laced, you know."
I laughed at that. "It doesn't sound like it at night."
That made Mom laugh. "I guess we have gotten pretty hot lately. It's just that you have me so worked up I can't stand it. Your Dad seems the same way at night."
We looked at each other, smiling. "Jan," we said together.
Then Jan walked in, rubbing her eyes. "I don't know what got into me last night. I slept like the dead."
I looked at her and smiled. I knew very well what had gotten into her last night. Me.
Jan got her coffee and the three of us sat chatting. Mom seemed particularly animated and after her initial jolt of caffeine, so did Jan. Sitting there with my Mother and Sister, both of whom had sucked my dick, was one of the most exciting experiences I could have imagined. Several times Mom or Jan had to jolt me out of my revery. I did notice, though, that the conversation flow seemed to be concentrated between Jan and Mom. They made a lot of eye contact. "Hmmm," I wondered. "What is this?"
After breakfast the sun was beaming down, so we agreed to adjourn to the pool. Jan and I went to our rooms to change into our suits, and I gave her a quick synopsis of the conversation Mom and I had. Jan's face beamed. At the pool, we all three got in and horsed around a lot. I managed to get surreptitious feels of both of them, and both of their hands found their way to my hard dick. The real fun, for me at least, was watching the horseplay between Jan and Mom. Once I was looking away and when my focus returned to them, both hanging from the diving board at the deep end, I was almost certain I had seen Jan's hand on Mom's ass. Mom gave no sign of it, but when Jan's eyes met mine, there was a hungry smirk on her face.
When we had our fill of swimming, we moved to the lounge chairs. For the past few days at the pool I had been responsible for putting sunscreen on Mom, but I was supplanted by Jan. I was laying on my stomach with sunglasses on, and I took advantage of the lesson Jan was giving on sensuously applying sunscreen. Her movements were gentle and smooth, where mine had been more aggressive. I squirted the sunscreen on Mom's back and then rubbed it in, while Jan squirted it in her hands first. After finishing Mom's back, Jan didn't hesitate. She put some lotion in her hands and started on the backs of Mom's legs. Maybe I was wrong, but I thought Mom was making slight little hunching motions against the lounger. There was no doubt that Mom spread her legs for Jan, who took advantage of it and rubbed the sunscreen right up to the edge of Mom's pussy.
