Martha's blush deepened and spread, and her nipples hardened and she felt hot and open 'down there'. Frank put his arm around Martha and gently kissed...her on the cheek... "There is something else I want you to do; I forgot to mention this before," he whispered in her ear."What?" Martha asked with a combination of fear and excitement."Go back to the bathroom, take off your bra, and bring it to me." No, Martha thought, I could never do that. Every one would know. She was wearing a very expensive. Margaret, never Maggie, she had told me the evening before, had moved to her handbag and was unzipping a side pouch.Returning to the bed, she opened her palm to reveal a pair of chrome nipple clamps. Unlike the ones I had used before, which were fashioned like a stiff tweezer, these were heavy metal rings with adjustable plates that screwed down from either side. Each plate was textured to grip, and the clamps were large and heavy."Keep still," she instructed before putting the first clamp in. As we walked, the route becomes rockier and wet, making for treacherous footing requiring concentration. However, I find myself distracted. Sue is in the lead, and as we climbed the rugged path, her shapely legs plus peeks of tan line butt cheek below her athletic shorts contributed to more than one stumble on my part. I swear she knows the effect she's having on me and pulls her shorts up higher while giggling at my distraction."Your such a damn tease, Sue!" Why Thomas, I don't know what. His cock disappears. The slick, frankly dirty sound of it nudging then entering my throat makes him swell. I draw back, lips closed tightly to pop from the flared end and kiss it. "How's that?" Exceptional."Reaching to my side I retrieve his belt. Hold the buckle and flick the tip around his bottom, grabbing the other end so he's trapped in a leather sling. The shirt tails split either side of his solid, wet meat and I pull the belt ends until he rests against my mouth. Open. Glide, tugging him.
