Before the day was over, Kristen, Duane and myself all had another shot at skiing and then it was time to head in and get home. We were all exhausted and had more that our share of sun for the day. Leaving the boat moored, we put out shorts back on, carried our stuff back to the SUV and before long, we were ready to be on our way back home. Just as we were ready to go, Kristen pulled me over to the side with a conspiratorial look.
“OK, you had your fun, no small thanks to me i, night add. What do you say we give Duane something to remember on the way home?”
I knew exactly what she was leading up to. Whenever Kristen said something about giving a guy, “something to remember”, it invariably involved some memory of him fucking her. Duane was cool and he was by no means shy or afraid to be a little aggressive in public when it came to sex (why do you think I love him so much?), but he DID have his limits. While I may have been stretching those limits a bit with things like sitting on his dick while in the boat, he still wasn’t at all comfortable with being seen fucking me by my parents and the same would apply to doing Kristen with her mom watching. Even then, it wasn’t that he didn’t WANT them to watch, he was still operating under the mistaken impression that my parents were like most other parents and didn’t want to see their daughter fucked in front of them. Someday we would cure that impression but for now there nothing I could do that wouldn’t have had potentially dire consequences.
“Hang on Kristen, you know we can’t do that,” I sighed, “Duane isn’t ready for that yet.”
“Well ... when’s he going to propose to you so we can get this over with?” Kristen teased me. I just pretended to pout although I have to admit, the idea wasn’t all that unattractive.
“Tell you what, I’ve got a better idea,” I said to her, a grin breaking out on my face as an idea came to mind. “It’s been ages since we raced. Wanna do it with Duane watching?”
Kristen giggled and looked at me to make sure I wasn’t kidding. I looked at her and waited for a response, as if I didn’t know what it was going to be before I even asked.
“What’s the payoff?” she said, taking my challenge seriously.
I thought carefully and then I knew just the bait for her. I looked over at Duane who was talking to my mom and aunt as they checked over the last of the stuff in the SUV.
“Winner gets my boyfriend when we stop for supper.”
Kristen’s face lit up and she grinned nastily at me. “Ha! You’re going to regret THAT bet. No way I’m losing this time.”
“You’re on!” I challenged her and we kissed to seal the deal and headed to the SUV.
“What’s with you two, eh?” her mom said, seeing us giggling and playing with each other as we ran back to the SUV.
“Oh nothing,” Kristen lied through her teeth. Her mom looked at her in total disbelief. She knew her daughter better than that but she also knew her well enough to not ask again.
Poor Duane had no idea what he was being led into. This time he automatically took the middle seat, as uncomfortable as it was, while Kristen and I flanked him again. Maybe the looks on our faces, but something seemed to tell him we were up to no good; he just couldn’t quite figure out what that something was. We waited until we’d been on the road about fifteen minutes and his alertness began to sag as we talked about the day’s events. Kristen was the one to finally get things started - as usual. She motioned for me to come in closer and we both got up next to Duane.
“You know Duane, Kelly and I have always been a little competitive in case you haven’t noticed,” she started off. Duane laughed and started to reply but Kristen kept going and cut him off.
“When we were teens we use to see who could masturbate and get off the quickest.”
Well THAT got Duane’s attention and he looked at me and I just shrugged with a “what can I say” look.
I took over the narrative at that point, saying softly to him, “So what do you say, wanna referee us?”
Duane looked a little confused, obviously not sure what I meant for him to do so I tried to explain further saying, “All you have to do is watch and determine who cums first.”
Duane looked at me, then at Kristen, and then at me again as if we had become two aliens from outer space.
“I’m dead SERIOUS,” I said to him, trying to get him to accept what we had told him.
He still seemed to think we were pulling his leg so Kristen backed into the corner of the seat and slipped off her shorts and thong, sitting bare-bottom on the leather seat. She put one foot up on the seat and turned to face Duane, spreading her hot little pussy apart with one hand while she cupped a perky boob in the other.
“I think she’s ready to go,” I giggled, “Are you? Just sit there and watch, it’s all you have to do.”
He didn’t say anything but still I think he thought any moment we were going to laugh at him and tell him it was all a prank. If he WAS still thinking that way, it probably stopped when I did the same as Kristen was doing on the opposite side of the seat. He couldn’t see us both at the same time so it was rather comical to see his head twist back and forth to try to see what we each were doing.
Meantime, my mom and aunt were carrying on like nothing in the world was going on in the seat behind them. I knew it was a bit of an act as there was no way they couldn’t have known something was happening. They were just cool enough moms to ignore us and let us have fun. Duane didn’t know it or he might have felt a lot more anxious than he seemed to be now.
Kristen and I started masturbating in earnest, each of us having our own distinctive technique and style. Personally, I’ve always been a finger girl myself, preferring to push a finger or two into my pussy and pretend they were a boy’s dick in me. My clit was also a favorite target and usually I tried to pay some attention to my boobs although my crotch was the primary focus point of my attention when I was really trying to simply orgasm and get it over with. Sex toys such as dildos and vibrators are not usually part of my masturbation routine although now and then they make for an interesting diversion.
