The sight of Susan on her knees between my legs was so incredibly erotic.
By this time she'd gotten a few different sets of the lingerie I told her to get and when we passed each other in the hallways at the office she'd look at me with a small smile and lust in her eyes. I knew she wore no panties and no bra as I'd instructed her and I could imagine that hot body underneath her clothes with ease.
Gradually she'd started wearing higher and higher heels and more revealing and tighter clothes over the past few weeks but the change was so gradual that no one seemed to notice. Except me of course!
When she arrived at work in the morning in her flats she'd change into her lingerie and heels when alone in the Women's Room so her husband never saw what she wore for me. When she knew she was going to meet me while we stole a half hour together she'd add a skimpy lacy thong because that' what I wanted her to wear while she was on her knees with my hard cock in her mouth.
A few days before, I'd caught her in the hallway by chance as everyone else was out or in the break room eating. We passed each other just as we were outside a broom closet and on a whim I grabbed her by the arm, opened the closet door and pulled her inside.
With the door shut there was just enough light to see each other once our eyes adjusted. I pushed her against the wall and started kissing her. As usual she wrapped her arms around my neck and pushed her body against mine, and as usual she started moaning deep in her throat as I took what I wanted from her.
Moving away for her just enough while still kissing, my tongue in her open mouth, I unfastened her jacket and opened her blouse, freeing her luscious breasts and fondling them. Her moans increased.
You may laugh, but I'd started to carry a handkerchief in my breast pocket. She was noisy when aroused and she was aroused so easily. I pulled it out and stuffed it in her mouth and then bent to take each nipple in my mouth while teasing the other with my fingers. If I didn't use the handkerchief she could have been heard down the hall and she gladly accepted it as a kind of bondage trick. I loved the wide-eyed look she'd give me when I silenced her that way, so submissive and so passionate.
I licked and sucked her nipples and rolled them between forefinger and thumb, squeezing just hard enough to make her moaning drop in pitch a note or two, and then returning my mouth to suckle the erect nubs.
Meanwhile her hand had found my cock through my pants and she was rubbing it almost frantically. She alternated between using her palms for the friction and using her fingertips to trace the outlines of the hardness she always so desperately wanted to feel.
When she began fumbling with my zipper I stopped her and stood up, falling on her lips with mine and invading her mouth again with my tongue. I pulled away after a few moments and told her to put her hands on her head. She obeyed instantly and I held her neck with one hand, pushing back against the wall, looking her in the eyes.
They were hooded with passion. She bit her lower lip and looked back at me, the expression on her face telling me she wanted me to do whatever I wanted with her. Her chest heaved and her bare breasts stood high there, and rose and fell with her nipples erect. She kept her fingers laced on her head and waited submissively for whatever pleasure I elected to give or take from her.
Keeping my eyes locked on hers I reached down to one thigh and moved it up under her skirt, just below her sex and close enough to feel the moisture that was starting to seep down her thighs. I stroked up and down and then moved to the other thigh and repeated the motion, just teasing her and watching the need mount behind her eyes.
My hands slipped around behind her, caressing and needing the firm, smooth flesh of her tight, round ass, I slipped a finger and ran it gently up and down her crack and then I found her little hole and circled and teased it. She pushed herself back against my finger and I responded by pushing against the muscles that kept it closed.
Her response was a series of pure animal grunts as I pushed in and finger fucked her ass. It was driving her wild but it wasn't my target. I pulled my finger out and offered it to her mouth. She started sucking my finger without a second's hesitation, licking it and sucking it like a baby's bottle, cleaning it and getting it wet for its next destination.
I finally took mercy on her and reached down under her skirt and up, brushing the lips of her pussy with the barest of pressure. She started to writhe and push out from the wall, trying to get my fingers to move inside her.
I kept up the teasing until I was brushing up and down the length of her nether lips and she began to moan and squirm like crazy as I first pushed one finger in between her lips and then pulled out and moved up to circle her clit and moved back down and into her again.
Her eyes stayed closed then, and her mouth opened and closed as I teased her, her chest rising and falling. I pushed my finger all the way in. She was soaking wet and I finger fucked her for a minute or so before I pulled out and settled on her clit.
As I circled and stroked her clit, going fast and slow, going gently and then harder, I started kissing her again and she lowered her arms and wrapped them around my neck, pulling my lips tight against hers.
She was absolutely gone now. No mind left, just need and lust as she writhed under my touch and it wasn't long before she started bucking against my fingers and coming. Her wetness coated my finger and the sweet smell of her sex filled the small space.
When she finally relaxed she looked at me and then with a ferocity I hadn't expected in her spent state she yanked open my belt and zipper and fell to her knees, her mouth enveloping my cock and her moans began again as they always did when she sucked my cock.
Now I needed to come and she knew it. Although she knew how to pleasure my cock just the way I liked it, the way I'd taught her, slow and sensual with lots of tongue, she could sense the need I had built up and I suppose we were both aware of the hour now.
Time had been suspended as I made her come for me, but now we knew there might not be many minutes left before the halls were filled with people again and so she bent to her task with a will, sucking and stroking my manhood and telling me to come for her.
It didn't take long. I exploded in her mouth and she swallowed my seed and looked up at me gratefully, and then she rose and we put ourselves back together and managed to get out and to where we each needed to be without being discovered.
That time, anyway; the next time we met we almost got discovered.
----------------------------------------
There she was, in the moment when I started this part of my story, on her knees between my legs, and she looked so sexy, so incredibly erotic.
It had been a few days since I'd pulled her into the broom closet and made her cum for me before she used her mouth to send me to sexual heaven. I have to tell you, this woman just loved sucking my cock.
The intervening days only seemed to heighten her need to be with me. I got messages from her more than once a day asking when she could be my slut again but circumstances kept intervening.
That day as we passed each other in the hall she stopped me with a hand on my shoulder, leaned in and whispered in my ear, "When can I suck your cock again?"
