My name is John and I have always been very bi-sexual. I can't imagine anything better than a nice pair of tits in my face and the thought of a cock in my mouth or in my ass makes me harder than granite. Joe, on the other hand, is straighter than a ruler; even the thought of lesbian sex holds no thrill for him. My wife, Kelly, is very bi-curious and Joe's wife, Sarah, is a committed bi-sexual.
Kelly and Sarah met at college. They were both taking an independent degree program for adults who were past the traditional college age, Kelly was 37 and Sarah 34. Usually such people couldn't attend regular college classes because they held jobs and had lives. The courses were basically self-designed and pursued with the guidance of a college professor acting as advisor. Kelly and Sarah came together at the monthly group discussions. Kelly was working on an environmental study and Sarah's subject was something she called "sex and society." Sarah wanted to get a degree that would allow her to become a sex therapist for married couples.
At middle-age neither woman has the body of a model. Kelly has delivered two children by Cesarian and has the belly to prove it, but she also has a 40DDD chest on a five foot frame. She has long brown hair which hangs down just below her shoulders, a wide, sweet ass, and a pussy she shaves regularly. Sarah is taller, closer to 5' 6" and heavier with a large ass and 48DD tits. Her shoulder length hair is brown and she doesn't shave, but rather trims her bush neatly. I am 44, 5' 8", and a little thick around the middle with a 7" cock that's about 1.5" thick. Kelly and I had started exploring BDSM earlier that year, so my cock, balls, and ass were clean shaven. I would come to learn that Joe is taller than I am, coming close to 6' tall, heavier with a larger gut, and his cock is a bit thicker and closer to 8" long surrounded by a dense black thatch.
Kelly and Sarah became friendly and with my urging Kelly broached the subject of bi-sexuality, partner swapping, and group sex. The ladies had a lengthy, sexually charged, chat one Saturday afternoon. If they hadn't had to return to class so shortly they might actually have tried to find a quiet, out of the way, disused classroom but as luck would have it that would have to wait. Sarah was frank about her bi-sexual nature and made it plain that Kelly was attractive to her but regretful that such pleasures were nothing Joe had any interest in. Kelly suggested swapping porn and seeing where things went. It was a happy coincidence we all lived in the same town and an odd one that we'd never met before, it being a small town.
I suggested to Kelly that we have them over for dinner and a movie one night, just to break the ice, so to speak. After a flurry of emails, it was arranged. We sent our daughter on a sleep-over with her friend and that evening Sarah and Joe came over. Dinner was a simple affair and the table conversation started light but soon became charged with sexual innuendo which rapidly developed into an open discussion of sex. Kelly was wearing a blouse with a plunging V-neck showing a grand canyon of cleavage which Joe had been eyeing all through the meal and when he finally loosened up, he told her she had a great pair. Sarah talked about her favorite toys and Kelly her favorite positions. Playing off an off-hand comment, I mentioned that Kelly gave the greatest head and we all talked about the strangest places we'd had sex.
After dinner we went into the living room and I offered a choice of some movie or porn. I was not surprised to be told to put in the porn film and selected Dark Paradise, quite possibly the best BDSM film I've ever seen. Despite his claim to not care for girl-on-girl action, it didn't take long at all for Joe to be visibly excited as he shifted uncomfortably trying to relieve some of the pressure on his swollen cock trapped by his pants. Joe was seated between Kelly and Sarah on our futon and I was sitting nearby on the floor.
Kelly leaned over to Joe and softly asked, "Would you like some help with that?"
Joe was clearly surprised, unsure what to say, and cast a quick nervous glance at Sarah, who studiously ignored him and focused on the whipping going on on the TV. He looked sideways at Kelly and, barely above a whisper, said, "Yes."
Kelly's hand slipped over, rubbed his swollen groin, then undid the restraining button and unzipped his fly. The sound of the zipper was loud and if Joe had looked at Sarah, as I did, at that moment, he would have seen her wide smile. He was more than a little overwhelmed by another man's wife slipping her hand into his underwear and grabbing his cock and didn't dare to look at his own wife from whom he completely expected at least shock if not outrage. Sarah just smiled and winked at me and I smiled back.
Kelly was slowly and steadily stroking Joe's cock while Sarah and I were alternately watching the TV then her and him. Joe's attention was fixed on the ceiling but every few moments he'd turn to look at Kelly. He was far too afraid too look at his wife but curiousity, or guilt, finally got the better of him and when he turned to see if she noticed that her husband's cock was in her friend's hand she smiled again for him and turned to me. She made sure he was still watching with a quick glance out of the corner of her eye, pulled up her skirt and spread her legs wide, revealing her panties. She began rubbing herself over her panties with her pointer finger watching me the whole time except for an occassional quick sidelong glace to make sure Joe saw.
Kelly slid Joe's underwear down as he sidled around on the futon, pulling his cock free. With a mischevious grin and a lick of her lips, she leaned over his lap and licked the dollop of precum oozing off the head and glistening on her hand. Joe lost all self control and moaned loudly. Kelly took that as an invitation and dropped her mouth over the head and shaft of his cock, working in slow moves, up and down. Sarah laughed, pulled her panties aside, looked me right in the face, and in a commanding tone said, "Eat me!"
What's a guy to do? I scooted inbetween her knees and went to work. Spreading her lips apart with two fingers, I lapped at her pussy a few times then slid my tongue into her as deeply as I could and licked everywhere my tongue could reach. Sarah placed a hand on either side of my head and held me so close to her pussy that her pubic hair was itching my eyes. She kept me going like this for a few minutes then pushed my head away and took a deep breath.
"I'm not quite ready to cum just yet, John," she said grinning as she sat back. Her smile disappeared in an instant, she looked hard at me, and said, "now strip!"
I shucked my clothing as quickly as I could and stood before her with a raging hard on, which I expected she'd suck on as my wife was doing for her husband. She caught me by surprise when she looked up at me and said, "On your knees!"
I stood there for just a moment too long. Kelly and I had played at D/s and I knew what was expected, but I just didn't expect it from Sarah. She rapped my cock with her open hand and said, "On your fucking knees, cocksucker!" Kelly had spanked me a few times and used a small whip on me, but she'd never actually hit me. I dropped to my knees but that wasn't enough, she said, "Down!" and I dropped to my elbows looking up to her from lowered eyes. My cock was harder than I could remember it being.
Kelly came up for air and asked Joe if he wanted more to which he nodded. "That's not an answer, Joe," Kelly said.
Joe said, "Yes."
"Yes? Is that yes, it's not an answer, " Kelly teased, "or yes you want more?"
"Yes, I want more, please," Joe groaned. He sounded almost desperate.
Sarah asked me, "You think Joe wants more cocksucking, John?"
I said, "I think he does," eager to be getting into the action.
