To say the last two days have blown my mind would be the understatement of the year. I wasn't a virgin by any stretch of the imagination, but I also wasn't what I would call uber experienced. I'd had sex with my current girlfriend Amanda on a semi-regular basis and a few past girlfriends from time to time before Amanda came into my life.
I wondered how the new changes to my sex life, Jenny's desire to have an ongoing sexual relationship and even my own mother seeming to want the option of tapping my cock from time to time, were going to affect things. How much of this would I or could I or should I ever tell Amanda?
We still had a few more days of vacation for me to consider all this before I had to face Amanda again. Part of me felt guilty about what I'd done, especially with Trish, Amy and Donna, but that was in the past and I can't go back and change it, even if I'd wanted to. For some reason I felt much less guilt about Jenny than I had the girls. In retrospect my sister wasn't the ogre I'd made her out to be. In fact, once you got her juices flowing she was a very sweet, intense, active sexual partner. I wouldn't at all mind having a little more sex with her, but now that we were almost at the lake, there was little chance that would happen.
Mom... well I don't even know what to think about that. She clearly is getting enough from dad, so why she sees the need to fuck me as well is, well, a mystery to me. I wasn't all that sure Dad liked the idea, but he seemed to accept that it happened and let it go, not blaming me at least. I had no idea what conversations they'd had about it when I wasn't around, but now that dad had done Jenny, he really couldn't complain about mom doing me, at least not in my opinion.
Lake Powell is an interesting lake. It's probably about a hundred miles long, with lots of twists, turns and back bays. I shudder to think how many hundreds of miles of shoreline it has. It is, for lack of any better way to describe it, a massively long canyon that is full of water. The shoreline varies between small gravel or muddy, sand beaches to vertical cliff walls. It's a popular destination for houseboat vacations, which is exactly what we were doing next. Out of the hot sweaty, desert and into a nice wet lake.
My parents hadn't been particularly forthcoming on what the plans were, but from what I could pick up overhearing their discussion on the way from Bryce, we were meeting my mom's sister, Aunt Mary, there for three days on the lake.
Ever since I was a much younger boy full of hormones I had to admit that Aunt Mary was a turn on. I'd only normally seen her in the winter, at Christmas and such, but on one occasion when I was a lot younger, I had the chance to see her in a bikini. Back then I likened her to what I considered a Playboy model to look like. I often wondered if she realized how much I fantasized about her hot body. She was several years older than my mom, probably about forty-five or six. I'd always thought she was pretty straight laced, until my mom told me about the two of them doing Uncle Jack when he graduated high school. I could almost picture the two of them naked, one sitting on his face and the other on his cock, both of them completely naked. Just thinking about it now was giving me a pretty good hard-on.
"Here we are!" my dad said cheerfully as we pulled off the highway into a large marina. He drove down to the office and stopped. "Be right back," he said as he climbed out of the cab. I climbed out to stretch my legs, which had gotten pretty stiff on the four hour ride from Bryce canyon.
I stretched my arms over my head and bent over to stretch my back. I felt a hand slide across my ass and down between my legs, grabbing my half hard cock through my shorts. "Too bad we're not going to get to play more. I could really use a little more of this."
"Stop," I hissed quietly, looking around as I stood up.
"What's the matter? Not used to being groped? Us girls have to put up with that kind of thing all the time," Jenny said quietly with a grin.
"Somehow I don't think you were doing that to teach me what a girl goes through."
"Not really. I just wanted to feel your cock," she said with a giggle.
"So you don't mind if I just do this?" I asked, sliding my hands up under her shirt and grabbing both of her boobs, gently squeezing them.
"Not if you don't mind me playing with your cock," she grinned, grabbing me through my shorts in response.
"Really you two?" Mom said as she walked around the truck to where we were grabassing. "I'd have thought you had enough of that this morning."
"Just getting my fill now. Doesn't sound like we're gonna be able to do much of this on the boat," Jenny said as she let go of me.
"Well, probably not," my mom agreed.
"All set!" Dad called as he came out of the office. I pulled my hands from her shirt and opened the truck door to let Jenny slide in before I climbed in after her. My dad started the truck and we wound down to the water's edge and drove down an access road that led to no less than two dozen large floating docks lined with assorted kinds and sizes of boats. He finally stopped by one lined with a variety of what I had to say barely looked like a boat at all. Dad got out and headed down the dock, pausing once to let mom catch up. They walked hand in hand down the metal dock, dad checking the berth numbers until he came to fifty-seven. He stepped across from the deck plating of the dock onto the boat and stepped to a patio style door on what I would call the front deck.
"SUZANE!" I heard my Aunt Mary call loudly as my mom stepped in through the open door.
"After you," I said to my sister. She shrugged and walked in and I followed her, Aunt Mary moving to hug her and then stepping to me for an equally tight hug that pressed her big breasted chest tightly against mine.
"We're so glad you could all make it!" she gushed with a huge smile. "The girls are up top sunning and Russel is futzing around doing something upstairs too."
"We need to unload some stuff from the truck first," my dad said, intending the comment for us to not disappear.
"Oh my goodness. RUSSEL! GIRLS!" she called out the patio door. "Go on up and I'll send them as soon as they come down," she added to my dad, as if that explained everything.
My dad led the way out and we followed, walking back to the truck to get our gear. I grabbed an armful, including my duffel bag, and turned to head back to the boat, bumping headlong into a cute blonde that looked a couple years younger than me. "Oh sorry," I said quickly as she backed up a step. She was a little shorter than I was with long blonde hair pulled back in a braid. Her breasts were full and round, easily a nice C cup, the tiny red string bikini exposing huge expanses of her breasts.
"No problem," she answered sweetly, stepping to the side to let me pass before stepping to the side of the truck to collect a cooler that my dad was holding.
I looked back at her as I walked away, her back half looking totally naked except for a few little red strings holding the triangles of red cloth that struggled to cover her front side. I nearly walked off the edge of the dock and into the water I was so busy staring behind me.
