Five years ago, my wife (Amy) and I took a weekend break to Germany, staying at a beautiful spa facility in the countryside. At the end of our first day, Amy suggested we visit the gym and spa before heading out for tea. I was always turned on by Amy in her lycra, her black leggings tights across her shapely bum, a sports bra fighting to contain her 32DD breasts and her flat stomach on display. Amy threw her blonde hair into a lazy ponytail as she completed her workout, and I watched from the treadmill as I completed my run. After a workout and a brief swim we made our way to the sauna. Peering inside we noted that this particular resort took a continental approach, meaning costumes were off limits. As I hung my shorts and wrapped a towel around my waist, Amy peeled of her bikini top to reveal her full round breasts, and stepped out of her bikini bottoms. We entered the dimly lit room, I sat on the top bench whilst Amy lay her towel across the hot bench and stretched out on the bench beneath me. Over the next 5 minutes the room was interrupted by bursts of cold air and a beam of clear light as other guests came and left, before it was just us two left in the room. Amy laughed and said we get up to anything, and rose to her knees in front of me. Her oiled and sweaty breasts brushed against my inner thighs as she slowly lowered her mouth onto my rapidly swelling cock. At that moment, the door opened again, and another burst of cold air entered the room. Amy, Rose to her feet to sit next to me, and I leant forward trying to use my frame and darkness to hide my erection. A tall German man, with cropped curly hair, and walked in with the confidence that a toned upper body and six pack allows entered the sauna and gave us each a smile as he sat on the beach opposite. Sitting on his towel, my eyes were drawn to his shaved crotch. I could tell Amy's were too as she whispered into my ear, "his cock is bigger than yours" before she casually brushed her hand against my shaft. Time passed, and I enjoyed the tension that sat in the air. Knowing my wife was enjoying this strangers body from afar as he tried to subtly take in her curves. After a couple of minutes, Amy stood, and stretched her body out with disregard for her towel and asked our German guest if she could add more water to the stones. He nodded, but made no attempt at eye contact as Amy walked across the room, she picked up the wooden spoon and placed her hand on his thigh as she leant over him to pour. The poor man never stood a chance. Making a show of pouring the water, Amy replaced the ladel with the ceremony and grace of a dancer, all the while leaving her hand resting on his thigh. As his cock twitched and swelled, Amy turned to me and said "his cock is definately bigger than yours James". With that our German aquantaince placed his hand on hers, and before leaning in to kiss him my wife whispered "I wonder if it tastes as good". They kissed passionately before Amy dropped to her knees, her heels resting against her curved bum cheeks. I watched as she slowly and sloppily worked the head of his cock and shaft, amazed at how turned on I was. She inched her mouth further down his shaft before gagging and gasping for air. She batted his cock against her tits before taking aim and swiftly rolling her hand over his shaft. Our guest twitched and shuddered before unloading four streams of cum. The first shot was across my wife's neck, before she allowed him to alternate between each of her breasts, before giving one long final suck. Standing, Amy turned to me with a broad smile, the cum dripping down her breasts mixed with her sweat, she leant into me, and let her boobs brush against my chest before whispering "yours tastes much better". I asked if it was my turn, to which she smiled and said you can have much more than that after tea tonight... And she was as good as her word.
