Note: I suggest you read the earlier installments of this story before reading this part.
Carla and Andy followed Sarah back to our table after a suspiciously long time in the bathroom. As Sarah approached, I looked at her and cocked an eyebrow inquiringly. She just smiled back at me and mouthed "later." I suspected something had gone on in there, but knew enough not to push her to find out what it was. Just as they got back our main courses arrived and we proceeded to eat them. Neither Carla nor Andy gave me a clue as to what had transpired, and everybody carried on with the meal as if nothing had happened. I participated in the conversation and hoped that Sarah would fill me in later.
Having had enough wine already, we all switched to soft drinks as we finished dinner and had a delicious dessert. The four of us were flirting with each other, laughing, and having a great time. We had gotten quite friendly with Carla and Andy which, given the circumstances of all that had occurred since they had arrived a little more than 24 hours earlier, was not very surprising. Sarah's a very physical woman, and a number of times I saw her put her hand on Carla or on Andy. A couple of times she even reached across Carla's lap to squeeze my thigh as she laughed in response to something I said.
After splitting the bill, we headed back to our car. As I walked next to Sarah, with Carla and Andy a few steps behind, I quietly asked her what had gone on in the restaurant. She again gave me the same smile as earlier, and said in an equally low voice, "Don't you worry, love, I'll tell you later." With that, she patted me on the ass and continued walking toward the car.
As I got in, Andy started to get into the back seat behind me, and Sarah said to him, "Why don't you go ahead and sit up front with Bob, Andy. Your taller than I am so you'll have more leg room and be more comfortable." Andy said, "Thanks," and got in next to me. Sarah got in behind the driver's seat, next to Carla.
"Bob," Sarah said, "let's show our guests around the town a little bit. They've never been here before, so maybe they'd like to see some of the sights."
I turned around and gave her a quizzical look. By this time it was quite dark and I wasn't quite sure what she expected them to see. "Um, honey," I said, "what did you want to show them in the dark?"
She responded, "Oh, there are certainly some sights. We can drive them around downtown so they can see Main Street, and we can show them the lake from the other side – the moonlight on the lake will be beautiful tonight."
I simply replied, "Okay, whatever," and drove off. We continued our conversation, mostly more gossip about people we knew in common. After a bit of this Andy and I shifted to talking about sports; we're both big baseball fans, but of other teams. Sarah and Carla continued talking in the back; I wasn't really following their conversation, but they were both laughing quite a bit. As I glanced in the rear view mirror, I could see they were sitting right next to each other, thigh to thigh. Sarah had her right hand resting lightly on Carla's left thigh, having inched her dress up quite a bit above her knees.
I drove them around the downtown area, pointing out some of the cute shops and restaurants that dotted Main Street. Sarah and Carla were quiet at this point, both of them looking out the window, as was Andy. At the end of Main Street, I headed north toward the opposite side of the lake from our house. Andy and I resumed our conversation, debating whose team had the best chance of making the playoffs this year.
As we approached the lake, I again glanced in the rear view mirror and was greeted with quite a sight that I could just make out in the moonlight. The top two buttons of Carla's blouse were undone, exposing the top of her large breasts and a lacy red bra. Carla's head was thrown back on the backseat headrest, her eyes were closed, her lips were slightly parted and her legs were even more so. My wife's right hand was gently stroking Carla's breast while her left hand had disappeared underneath Carla's skirt. From the motion of her arm, it was quite evident what she was doing, which was mirroring on Carla's pussy what her right hand was doing to Carla's breast. Unbeknownst to me, Carla wasn't wearing any panties, because they were on her husband next to me!
I elbowed Andy and jerked my thumb toward the backseat. He swiveled his head around to catch a view of what the women were doing back there. He looked over at me for a second with a big grin on his face, and then turned back to watch the show. I felt left out, having to drive, so I cleared my throat and inquired, "Enjoying the ride, ladies?"
Sarah chuckled and replied, "Oh yes, Bob, you're being a wonderful chauffeur," and Carla simply said, "Ummmmmm." Just ahead of us was a small parking area near a private beach on the lake. I decided with all the distraction it was probably best that I pull in there before I got us in an accident. There was nobody else parked there, which was not surprising given that it was a private beach for a handful of houses on that section of the lake and it was quite a bit after sunset.
I turned the car off, but left the radio on and swiveled around to join Andy in watching the show in the backseat. The lights from the dashboard and the full moon reflected in the lake provided enough light to be able to see what was going on. By this time, Sarah had undone another button on Carla's blouse, and had unfastened the front clasp of her bra, freeing her breasts. She was now pulling and squeezing one of her nipples, while her other hand was working more furiously on her pussy. Carla's mouth was now open, her tongue hanging out, and deep moans were coming out of her throat. The smell of sex was ripe in the car, and my mind quickly flashed to whether Carla's leaking pussy was going to stain my leather seats right through her dress. But I was quickly brought back to the action at hand as I heard Carla's breathing and moans getting faster, and she started saying, "Yes, yes, yes, that's it, keep going."
And then Sarah stopped. She continued to tweak Carla's nipple, but she pulled her hand out from Carla's dress, much to her dismay. Carla's eyes shot open, and she looked over at Sarah and snarled, "You are SUCH a shit. I can't believe you did that to me again – I was so fucking close to cumming, you can't imagine."
Sarah just laughed and replied, "Oh yes, my pet, I certainly can imagine, and that's exactly why I stopped." She let go of Carla's nipple as Carla sneered back at her, "Tease!"
Andy laughed, and Carla gave him a dirty look. "So you think it's funny, huh? How would you like it?"
I looked at her and said, "Again?" But before she could answer, Sarah said, "Better be careful, boys, or you don't know what I might do. I'll deal with you two later," and she gave us a wink. She turned back to Carla and said, "Come here, sweetie," opening up her arms for her. Carla gave her a dirty look for a second, but then she leaned over and put her head on Sarah's chest, as Sarah wrapped her right arm around her. I looked at Andy to see if he knew what was going on, but he just shrugged his shoulders.
"I know you're frustrated, but I thought it might be fun to get you a little more aroused."
"Fun?" Carla replied, looking up at her. "Only fun if I can finally get satisfied."
