My blood turned to ice and froze my heart. Kelly wanted Marcy to think she was talking about me.
Marcy hesitated and then shattered me when she said; "I want to taste him first." Kelly looked at Dave, who nodded and was already washing himself off with a washcloth Kelly had brought out, and then said, "OK".
She took Dave in her mouth quickly just like she had done with me and gave him one long suck before releasing him.
Dave lifted his leg over Marcy's chair and straddled her torso. His cock brushed her face. She lifted her head and opened her mouth and took him inside of it. She started to slowly bob her head back and forth. I could see the inside of her mouth working to take him all in. Dave's head fell back in pleasure. If Marcy could tell the difference, she didn't mind it at all. I had never seen her give head except close up, but she was enjoying herself.
Kelly stood and watched the action for a little bit and then started to walk towards me. She knelt down in front of my chair, smiled at me, and then leaned down and took my cock into her mouth. All my pent-up anticipation was released as I felt the inside of her mouth surround me and her tongue playing with the underside of my penis. I had never felt pleasure like this -- it was so intense and so complex, but finally I just relaxed and let myself wallow in it, alternately looking at Dave and Marcy.
Just as I felt myself getting ready to go, Kelly abruptly stopped, releasing my dick from her mouth with a low 'pop', getting up, and strolling back to Dave, who was tensing perceptibly. She grabbed him by the hips and gently pulled him back, reaching around to grab his cock and squeeze the base of his shaft. Then she steered him back towards Marcy.
Dave needed no further encouragement. He climbed on top of my wife and split her with his cock, ramming her quickly and bringing a gasp of surprise and pleasure. Kelly mounted behind him as she had done with me last time and cradled his body in hers, guiding his motions with her body. Marcy responded immediately, beginning another climax.
I struggled against my bonds, wanting to get my share, wanting to be part of the action, but all that seemed to accomplish was to make more blood flow to my crotch. Dave looked bigger than me. Could Marcy tell the difference? Did she care?
Kelly kept Dave in rhythm, almost like guiding a kid learning to ride a bike. He learned quickly, taking Marcy over the edge while having little trouble controlling himself. Kelly let him go and produced another gag and used it to muffle Marcy's cries of pleasure while Dave continued his rhythmic fucking.
Kelly turned away and strode purposefully over to me. She put her feet on either side of my hips, raised herself up, and used her hand to guide my cock into her pussy. It was a scene I had imagined a hundred times in all different permutations over the last days, and when I felt her flesh contact mine I screamed with pleasure and release into the cloth muffling my mouth. Kelly moved up and down on me, mimicking Dave's rhythm. Her breasts hung down tantalizingly perfect in front of me, and I instinctively moved my hands to feel them, pulling against my restraint.
I'm not sure who of the other three came first, but whoever it was triggered the rest of us. I was somehow aware of Dave making an effort to keep his identity from Marcy but giving in to the waves of pleasure cascading through him. She was coming, straining against her bonds and convulsing in pleasure. But that was all in the periphery for me and Kelly. I strained reflexively against my bonds as I felt my balls pumping and fluid shooting up into her and my toes were curling and I was screaming silently and it was lasting forever but it was done to soon and Kelly ripped the cloth from my face and smothered my mouth with her lips in a full deep kiss, pressing her body against mine as she worked her hands up to the mine and loosened those bonds.
Feeling her breasts against my chest and her body wriggling against mine was magic. My arms came down on their own and wrapped around her. We lay there for a moment and listened to the sighs coming from the other chair. Then Kelly broke off, stood up quickly and untied my ankles. She grasped my hand and gently but quickly led me over to the other chair where Dave was disengaging himself from Marcy. She dragged my hand down to Marcy's bonds and released it. Without pausing, she grasped Dave's wrist and led him over to our chair. She pushed him down on it and quickly massaged his quickly growing crotch before mounting him.
I was fumbling with Marcy's bonds while I was watching this but caught on quickly and felt my cock hardening for action as I myself was. I quickly finished untying Marcy's hands, grabbed her hips and gently flipped her over onto her hands and knees, and then mounted her from behind.
She gasped with shock but quickly recovered and began to move in rhythm with me. As we started to really get into it, the sounds from the other chair intensified. Kelly was loud and her pants of pleasure reverberated through us. Marcy supported herself on one arm and used the other to remove her blindfold, looking over to see what was going on. After she got a good look at the action with Dave and Kelly she looked back at me and smiled. I felt my cock harden more and smiled back. A wave of intensity crossed over Marcy' features, fueling me, and she turned to concentrate on moving with me, peaking over at Dave and Kelly every so often. who were also occasionally looking over at us.
Dave and Kelly definitely came first this time, which sent me over the edge. I pumped Marcy with long strokes, coming in her as she tensed in climax and then slowly tailing off as she subsided with me. She collapsed onto the chair and rolled over and I lowered myself on top of her, exhausted. My body was tingling with the best post-orgasm feeling I had ever had, and I blocked out any thoughts that would interfere with that.
After a while we shyly and quickly dressed. It wasn't as awkward as last time, at least not for Marcy, but we declined their invitation for dinner and headed quietly home.
