I padded in bare feet the short distance down the hall from the bathroom to her bedroom door, the air cold on my damp skin. It had been a hard sweaty day in work and being able to have a quick bath before we got up to anything naughty was an absolute necessity. I was surprised to not find her waiting for me, usually she'd waylay me as soon as i stepped out of the bathroom and we'd indulge in passionate foreplay right there in the passageway, but tonight was different. I glanced to the right and could see the open door of the living room and the darkness beyond. I still felt odd and not a little vulnerable walking naked around someone else's house. Even though id been calling at her house for a few months the melodramatic paranoid part of me still half expected her estranged husband to step out from a dark corner wearing a ski mask and brandishing a bread knife. This unpleasant thought made me grimace as I looked down at my naked testicles. I shivered slightly, partly from the cold, partly from my vivid imagination but composing myself I tapped lightly on the bedroom door. "who's there? questioned a husky female voice. I smiled as I replied, "it's the car mechanic, i've come to carry out your servicing" she giggled, "oh, you'd better come in then, i hope you've got your equipment ready!" she giggled again. I reached forward and slowly pushed open the door. The ceiling light was off but i could see that the room was lit by the light from two small wall lights placed either side of the bed. But these things were instantly banished from my mind as a cough from Sarah made me look down at the bed. The sight that met my eyes made me stop in my tracks "oh my god! I exclaimed. She had thrown back the duvet and was kneeling on all fours on top of the mattress, head down on the pillow and her feet overhanging the edge of the bed. She wasn't naked, not if you count her short, lacey nightie as clothing. Nightie was a generous description for the flimsy scrap of material which moulded itself to every curve of her body but most striking of all were the parts of her that were left uncovered. Her beautiful white rounded bottom was pantie less, totally naked and thrust up towards me, her hairless pussy pink and pouting, her anus dark and vulnerable. I shook my head and exhaled a half whistle in a gesture of appreciation. Some women I'd met would only have sex in the dark, safely concealed beneath the duvet, " i dont want you to see me, im too fat" they'd usually say, seemingly unaware that by the time they'd got them into bed most men only cared that the woman had all the relevant girly parts in working order and was willing to share them. Even if i didn't already know from past experience, It was obvious from the naked form in front of me that, thankfully , Sarah had no intention of hiding under the duvet. I walked to the edge of the bed and looked down at this wonderful, wanton woman who was hiding nothing from me. "well, what are you waiting for?" she said, raising her head and turning to look at me, "don't you think you should start on that service you promised me?" I managed to drag my gaze away from her upthrust bottom and looked straight into her sultry blue eyes. She nodded towards my groin, " it looks as if your dipstick is ready to check out my oil level !" and she was right, my penis was now fully erect and pointing towards the bed and her warm vulnerable flesh. Leaning forwards i placed my hands on her bottom then slid them under her nightie along her back towards the nape of her neck feeling as they travelled the warm velvet of her skin under my fingertips. As i explored her body my penis lightly brushed against her bottom causing her to push backwards in a rocking motion, threatening to engulf me in her pink flesh, "not so quick!" i said in mock admonishment but secretly wanting to grab her roughly by the hips and take her there and then. I let my hands slide down and around to the mounds of her breasts. They weren't large breasts, but had protruding hard nipples which I rolled gently with my fingertips. "mmm!" she moaned softly. "dont stop there, i've got plenty of other buttons which need pressing" Bringing my hands back around to her shoulders I traced my way down her spine until i reached her soft bottom which i cupped with both hands, my thumbs tracing their way down the cleft of her buttocks lightly touching the edges of her pussy. My left hand again slid around to her breasts seeking out and pinching her erect nipples. She moaned in approval. I hesitated for only a brief moment before running my open right hand between her legs and sliding it down and around her pussy. Slowly I drew my hand upwards, my middle finger pressing between the moist lips of her aroused sex. She was so wet that it easily penetrated her and then slid back out again eliciting a gasp of pleasure as she pushed her bottom towards me. My own lust was rising, but without rushing I continued my upward movement until my finger came to rest on her puckered bum hole, i circled it gently, trying its tightness, my finger still slippery from her pussy juices. I expected her at any moment to recoil in horror from my intrusive hand, "oooh" she squealed, "you're a very naughty mechanic, you're supposed to be giving me a service not fiddling with my exhaust!" nevertheless she rotated her hips around in time with my probing finger. Involuntarily I laughed. " my god Sarah" I said, "you are one very sexy, horny woman," I again traced my finger down to her pouting wet vaginal lips, leaning forwards i kneeled at the foot of the bed to bring my face to within an inch of her glistening flesh. At this distance I could smell the heated musk of her arousal mingled with the scent of her perfume.
