I gave up the game and drew out her arms, kissing her palms and fingertips. I stroked the sides of her ribs, and then eased my hands under her to squeeze and pull at her butt, before raising it onto my knees, bringing her pussy back into view. Her lips were swollen and parted, a little bath water dribbled out. I put the base of a palm to her, fingers pointed up to her belly button and began to knead, and then slipped my thumb inside her, hooked upwards.
She groaned and settled her feet and shoulders more comfortably in the tub, and began to push back, demanding a faster rhythm. Her slightly raised posture allowed me to run two fingers along her crack, and then I probed and pushed my middle finger one knuckle deep into her ass. Her pushing stopped for a moment with a little gasp, and then a smile spread across her face. She resumed her rhythm, a little more slowly now. I let my finger rest where it was, until I felt her relax around it, then as she upped the pace again I pushed up to the second knuckle. This time she did not pause, and to the same beat I circled with my palm, flexed my thumb in her pussy and gently fucked her ass with my finger.
She lifted a foot to my chest, the bucking in the water growing faster and faster, and braced herself against me for more leverage. The other foot followed, trapping my hand between her legs. I took my finger from her ass and pulled her left foot to my mouth, sucking on her big toe. My finger went back in, more easily this time, and I increased the length of the stroke to almost the whole finger. Water splashed chaotically, and she seemed to be growling with pleasure. Then suddenly she pulled her foot from my mouth, and with both feet pushed hard on my chest. My hands came away and she arched in the water, and then splashed down again with a gasping moan, drawing up her legs and pressing them tightly together. Little spasms rocked through her. The blindfold had come off, but her eyes were still closed, and she was flushed bright red.
Her orgasm subsided slowly. She looked at me with half lidded eyes, then put her feet on my thighs, and spread her knees wide and began to masturbate. In time with her own strokes she took my member between her feet and stroked up and down the shaft, the leverage from her butt pushing her pussy against her left hand, her right hand was running along her body, which was now only part submerged.
I couldn't decide where to look, her breasts were still heaving breathlessly, her right hand roamed teasingly, her left hand gave glimpses of her cunt, and her pretty feet were wanking me energetically. I put my hands on her knees, and looked into her eyes. I came first, a spurt leaping from my cock, and then dripping over her feet as I broke the silence with an "Oh Yes". She didn't stop the foot job, but kept going until she too came, less violently this time, but at the moment of crisis squeezing me almost painfully between her heels, before settling tiredly into the remaining water.
I pulled her forwards, and then stood, and slipped behind her, so we were both facing towards the taps. She ran the water again, letting the cool and half empty bath refill. We lay back, her head resting on my shoulder, my arms loosely clasped around her.
