Carol, Kim, and I then went out on the lake. Carol and Kim went tubing and we had a great time. We started back in and i was standing up, driving the boat and I felt hands on me again. I turned around to make sure it was Carol this time, so since it was, I grabbed her ass. Kim said how come I didn’t do that to her before, and I said, because my hands were busy then, or I would have, since I thought it was Carol the last time. We got back in and ate a light lunch and found Bill and Susan just lounging. We asked them if they wanted to go out after we ate and they agreed. We spent most of the rest of the afternoon on the boat. Everyone went tubing, even me, with Bill driving the boat. The girls were also sunning most of the afternoon and drinking lots of wine. I regulated myself to two beers, and Bill was drinking a few too. We got back into shore around 7 that evening, and Bill and I grilled chicken for dinner. As we ate, Susan asked how I liked it there with them. I said I am having a great time, too bad we have to leave tomorrow. She said they usually come up for a full week in the summer, so maybe next year you two can plan that. Carol said that sounds good to her. I was thinking that Carol already see’s us being together for the long haul, which I was glad of. Kim just rolled her eyes and giggled. Carol said to Kim, well maybe you’ll have a man you want in your life and will bring him too. Kim laughed and said she wasn’t going to hold her breath.
Carol and I got a fire going in the fire pit and sat around with Kim, all of us drinking. Bill and Susan were heading over to some friends cabin, down the road from us. Susan said don’t wait up for them, that they’ll probably be real late. We all said goodnight to them and off they went. Kim laughed and said we know what they’ll be doing. Carol said that it sounds like fun, and then winked at me. I remembered back to us being with Pete and Karen and that fun we shared. Kim caught the wink and said, no way, you two even swing? Carol said that we have and told her bit and pieces. Kim was quiet, yet attentive to every word Carol told her. Then Kim said, fuck, how come I cant find a guy who is so trusting. Carol said they are out there, but that she got lucky in finding me. Kim said, I’d say, and do I have a clone hidden somewhere. I was feeling a buzz now, but the girls were definitely drunk. Kim said, let’s head down to the Ackerman’s, where her mom was and see what they are doing. Carol laughed and said we shouldn’t do that. Kim goes come on, it will be like when mom and dad used to have those parties and they thought we were in bed and we saw them screwing others. So we headed down the road and Kim went up to a window and looked in. she stayed there a minute then came back and told us to come see. When we looked in, Susan was riding some guy and Bill had the other lady on the couch just fucking her silly. Carol was holding me, and then her hand grabbed my cock and started stroking it. Kim said damn, mom looks like some porn queen, damn she is good. Carol said it looks like Bill is no slouch either, and Mr. Ackerman has a nice size cock too. I said you two are so bad and are corrupting me. Carol kissed me and said it feel like you are enjoying it. Kim looked down now and saw my hard cock, and said, wow, you really aren’t little are you. Carol said we better get back to the cabin before someone spots us spying over here. We almost ran back, laughing and giggling the whole way, and thankfully, my cock was going down.
We put out the fire and Kim went in to get another glass of wine for the girls. Carol kissed me and said something that floored me. She goes, do you love me? I said that’s a silly question, you know I do. Good, because I want to take you to bed, but i want you to eat my sister and make her squirt. She never has and I have teased her enough tonight, by telling her all this stuff. I said I cant do that, that’s your sister. She said big deal, just think of her like it is Karen. I said really? She said oh yes. I said she isn’t going to allow that, and Carol said don’t you worry baby, you may have two women tonight, and if she doesn’t want too, you are still going to fuck me, and that you can count on. Plus, my sister is so horny right now, she’d let my ex fuck her, if he was here, and she couldn’t stand him.
We went inside and found Kim sipping her wine, and handed Carol her glass. Carol took her by the hand and took her in the bedroom and closed the door. Who knows what she is telling her now. About five minutes later, and after some laughing in there, the door opened and Carol asked me in. When I got in there, I saw the drapes were closed and a couple candles lit, and the girls were laid out on the bed, but on the edge of the bed, with a space in the middle, between them. Carol said, come here baby, and lay down between us, but with your head down by our feet. Carol then told me to masturbate with them. My cock was almost hard when I got on the bed, but now it was at full staff.
Carol and Kim were sitting up against the headboard, their legs spread, and knees up so I could see both of their pussy’s, and their hand working all over them. I started stroking my cock slowly, with long strokes that I know Carol likes to watch. Kim was moaning, then said, damn this is so hot and Tim, you have a very nice cock. Carol said that we do this all the time and find it so enjoyable. Both girls were moaning a lot and Carol said that it reminded her of their days of masturbating together, and Kim said that she remembers those days too, and they were so fucking hot, then let out a loud moan, like she just came, but kept on going. I was getting close to cumming and told the girls. Carol moved and sat up, and took her hand and grabbed my cock, then lowered her head down and started licking it. My hand gave way to her ministrations, fuck it felt so good, and I told her so. I told her I wasn’t going to last long, and she motioned to Kim to come by her. Kim sat up then leaned over and started licking me too. I was thinking, holy shit, her sister is touching me. I looked at Carol and she just winked and went back to sucking. I was moaning real loud now, not caring if the girls mom came home or not, but why worry, they were down the road fucking too. Kim just released my cock from her hot mouth and Carol took it back in, and while she did, Kim played with my balls. I couldn’t hold off any more and told them I was about to cum, and let out a big stream into Carols mouth, then she lifted her head and Kim took some in hers too. Kim was finishing up whatever I was releasing and Carol came up and kissed me, using her tongue to push some of the cum into my mouth. Carol broke from the kiss, and told Kim to kiss me now, and without any hesitation, Kim kissed me deeply. After the kiss, Kim said, holy fuck, I have never done that with a guy before, then looked at us both and said you two are some kinky freaks. Carol laughed and said, who are you kidding, you enjoyed it too. Kim laughed and said, I never said I didn’t.
