It had been weeks since my mind blowing encounter with Rob and Sharon and we had yet to repeat the fantastical sex scenario. Twice I had returned to my balcony watch of the two of them, but it left me empty... only wanting to join in or not participate at all. I had the occasion to romp around the room with Sharon alone twice, but it felt more like cheating than a sexual epiphany so we stopped all together. What had developed however, was a bond between Sharon and I where we would spend time together talking about sexual fantasies and how to play them out. What we found was a shared need to explore my wife together and that thought carried me through to unknown sexual electricity. It seems that Sharon had always had a "thing" for Christine even though she had never really been with a woman before (other than some mild post-puberty experimentation). This, of course, was my dream come true! Quickly, we hatched a plan that would give us all what we wanted. Let me give you some background on Christine first. While a completely vivacious woman with a wild sex drive and an openly creative mind in bed, she is, and always will be a schoolteacher with a puritan sense about her. She has a strong sense of privacy and modesty that only makes her more appealing to me when she displays a raunchy side and exhibitionism. (This is also what shocks her schoolteacher friends!) Anyway, our kids spend a weekend every year with their grandparents at their cabin in Tahoe and Sharon and I had planned our game for that very weekend. While Chris and I often go along on the trip, we decided to stay at home for some "us time". I had dropped the kids off and drove home knowing what to expect when I arrived (since I'd already made the request before I left). Chris knows that I love it when she wears one of her long cotton sundresses with no underwear and only buttoned in the middle. This gives me access to her great breasts and snatch all the while she can stay semi clothed (A visual and tactile turn-on for me). Since I had already plied her with two champagne cocktails before I left, so I knew that she would be frisky when I returned. I was not to be disappointed either. Chris heard me pull in to the garage and met me at the door wearing one of my favorite dresses. Offering me a Bloody Mary as she rubbed herself against the entire length of my body. God I wanted to toss her on the floor and have her right then, but I knew that better things were on the way. She situated me in my favorite chair, handed me my cocktail and slowly began to unzip my shorts while I sipped my drink. Imagine her surprise to find that I wasn't wearing underwear as my cock sprang out in front of her face. She climbed up to give me a passionate kiss and then lowered herself back down, slowly stroking me to full erection as her dress fell away exposing her bush to me. While her tongue ran up and down the entire length of my shaft, I had managed to kick off my sandals and moved my right foot in between her legs. She was deliberate in her ministration as she began to suck my balls in to her mouth. I had, in the meantime, managed to get my big toe in to her slit and began massaging her from top to bottom, feeling the warmth and wetness of her on my foot. I gently caressed her mound and eventually found that the pad of my big toe could put pressure on her clit while I could fit four wiggling toes inside of her. This was a new experience that sent her far over the edge. Eventually, she let loose of my throbbing purple head and just lay her head against my thigh as I brought her to one shattering orgasm after another. After several minutes, she once again began to gobble down on my meat when I gave the signal to Sharon (my hand pressed against the window). Sharon often would baby sit or house sit for us, so it was not uncommon for her to have access to the house. While my sex-twisted wife was paying dividends on my manhood, Sharon walked through the front door, unannounced, wearing cotton shorts and a half top that did little to contain her surging breasts. " I'm sorry", she faked. "I thought you guys were...Oh wow!" It was then that she noticed my raging hard on, still untapped. Christine's mouth and chin, dripping with saliva, kneeling between my legs. "Mind if I help?" she asked. In her post orgasm euphoria, Chris was disoriented when Sharon walked in. So before she could answer, I said "Sure! The more the merrier!" It took Sharon, a little more than three seconds to remove her top and land beside Chris between my legs. Chris, confused at first, quickly got in to the mood as the two of them took turns licking and swallowing my cock. Sharon was fondling my balls and running a ring with her long fingernails around the rim of my ass, as Chris was taking me deep in to her throat. It was the most erotic sight of my life to watch these two pleasure me at the same time. As I was nearing my explosion, Sharon's hand moved down to replace my foot in Christine's pussy (Quite frankly, I had stopped all stimulation while lost in my own world of pleasure) and I could tell from Chris' fluttering eyes, that Sharon had found her "spot". Once again, Chris released my pulsing cock from her mouth and lay her face against it as her orgasm built to crescendo. Seizing the moment, Sharon grabbed my shaft and began pumping it up and down until I squirted load after load in to the air. Landing all over my stomach and both of the girl's faces. While still in the throws of her orgasm, Chris began to lick the cum off of me while Sharon was tonguing my seed off of Chris' cheeks and neck. Eventually, their mouths met in a soft wet kiss that lingered, while they explored each other with their tongues, passing my gooey load back and forth between them. While still in their embrace, Chris began to massage Sharon's breasts while I joined them on the floor and began to remove her shorts. All of the sudden, Christine pulled away and sat upright, realizing her surroundings as she came down from her orgasmic high. "Wait... what? What? What are we doing?" she stammered out. "Ted?" she asked, looking at me. I just smiled and nodded. It was Sharon who took control then. She rubbed her thumb up and around Chris' clitoris and said, "Relax, Christine. This is going to be fun." Chris' eyes rolled back in her head and I knew that she was lost to the hedonistic pleasures that awaited. I finished removing Sharon's stained shorts while Chris laid back on the floor, opening her dress and allowing Sharon access to her soaking wet hole. As Sharon began to tongue her gently, I moved behind Sharon, administering the same treatment to her. Running my tongue up and down Sharon's bald slit, circling her ass and pulling back her folds to reveal her rapidly swelling clit. While Sharon was on her knees over Chris, I turned over on my back and slid underneath her so that I could use my nose against her button while I lapped up her musky juices and probed her ass with my thumb. I could tell that she was getting ready to unleash the beast and intensified my efforts. I could also hear the steadily increasing moaning that was coming from my wife and knew that she was about to cum for the third time today. It seemed like they both came together as the wailing and thrashing about all coincided. Sweaty bodies squirming, humping and gyrating together like some bizarre naked worm inching across the floor. Me? I was just hanging on for dear life, with my tongue in Sharon's crack and a thumb in her asshole. When the girls' breathing came back to normal, we all just laid on the floor, reveling in the glow of what we had just experienced. I suggested a quick dip in the pool would all bring us back to earth and the girls agreed, walking proudly naked to the backyard and diving right in. I gathered a round of drinks for everyone and joined them in the pool. It was while we were all relaxing in the water that Sharon and I filled Christine in on the events of the past several weeks (leaving out the part about Sharon and I alone). I was afraid she would be upset, but the afterglow of hot sex was still upon her and she floated across to where I was and gave me a deeply passionate kiss. Then she slid to the left and gave the same kiss to Sharon. "Is it just me, or hasn't anybody been fucked yet?" Chris asked. That was all the encouragement that we needed. We left the pool and headed back to the house. Chris grabbed some snacks and fresh fruit, while I grabbed the champagne and some bottled waters. Once in the bedroom, the groping began again. The smell of sex hung in the air like a cloud. Then I suggested that the two of them get in to a 69 position. As this was new to Chris, she hesitated at first, but knowing this was also a fantasy of mine, she climbed underneath Sharon. Now Chris has always shaved her bikini line, but hesitates to shave her pussy because of the discomfort when it grows back. But as soon as she positioned herself face first to Sharon's bald patch, she exclaimed that she was going to stay clean-shaven from now on. Sharon's pussy was truly beautiful. A sweet little rose bud with just a wisp of hair above her entry. Christine went after Sharon in slow probing strokes that were long and wet (just the way she likes to be eaten) while Sharon was reciprocating at the other end. I reached my hands between the two of them and began to pinch their nipples and rub their clits between licks. Finally the two of them were in to a full on rug munching competition to see who was going to bring who off first. Since Sharon was again on her knees above Christine, I entered her from behind replacing Chris' tongue with my fully engorged cock. I slid into her just a little at a time as Chris played with her tits and clit. By this time Sharon was screaming in that same guttural cry as before and was coming buckets of juice all over my wife's face and hands. I scooped up some of what was running from her and liberally applied it to the opening of her ass as she squirmed from the pressure. Quickly, I removed myself from Sharon's pussy and pressed myself against her ass as she pushed back against me in one mighty thrust. She was so tight that I knew I would not last long and pounded in to her as hard as I could before emptying my seed deep in her bowels. Sharon collapsed in a heap and spasmed in the sheer physical joy of the moment. Christine lay on the bed, apparently spent, with an angelic smile on her face. Which caught me as ironic given the past several hours of activity. I fell in to the mattress completely ready for a full deep sleep and even began to drift off before Chris spoke up. "Sharon?" she said in a soft tone. "Would you shave me to look like you?" asked Chris. I was quickly awakened by this request and brought a bowl of warm water, fresh razor, towel and shaving cream. While my cock felt like it had no life left, I also knew that poor Christine was the only one not to have a good fuck yet. Sure, she's come several times with tongue, hand and toes, but.... A proper fuck was still missing. After all... this was all for her benefit. Our pleasure as well as her benefit. Sharon lathered Chris up and began to slowly shave her mound and labia as she also massaged her now tender opening while I watched in stunned silence. Christine gets hyper sensitive to touch after sex and was careful not to move too much while still enjoying the attention. When finished she proudly displayed her newly bald patch to me asking if I liked the change. Her beautiful lips were now bare with only a triangle of hair below her pelvic bone remained. The swelling in my cock was answer enough as she quickly mounted me in a 69 position and began to slather my cock with saliva. I was in total ecstasy with my wife's new hairless pussy pressing down against my tongue. Chris wasted no time turning around and impaling herself on me as we rode to orgasm after orgasm in a slow dance that seemed to last forever. I awoke the next morning to the smell of fresh coffee and linguica. Sharon had begun to make breakfast. Chris and I had fallen asleep in each other's arms and stirred at the same time. Walking downstairs to the kitchen, Sharon said that the sight of us making love together was the most beautiful thing that she had ever seen, because it wasn't about sex, but all about love. She excused herself and had slept in the spare room to leave us alone. I had to agree with her, but couldn't deny the power of the sex that we had had as well. "So..." I asked Sharon, "How's Rob?" Christine just winked at me as she sipped her coffee.
