This is a continuation of my stories The Stacks and Back to the Stacks
When I got to the little study niche by the glass room, I looked around and made sure that I was alone. Opening up the envelope, I pulled out Natalie's panties. They were damp; holding them to my nose, I inhaled her scent, the smell of her cum. I was dripping between my legs from the sheer eroticism of the evening and reaching under my skirt, I wiped myself with her undies, mingling my scent with Natalie's. Then kicking off my shoes, I stepped into the panties and pulled them up, snug against my crotch. I wanted to cum in them. Leaning back against a book case, my fingers started masturbating my pussy through the cotton. I pushed the cloth up between my swollen lips, stroking myself, my thumb pressing against my hard clit, two fingers grinding the cloth deeper into me. Imagining Natalie watching me, listening to me, smelling me, observing my orgasm and having her own was too much and I quickly came, exploded really, soaking Natalie's panties; mixing my cum with hers.
As I slowly came back to earth and the roaring in my ears subsided, I thought I heard the rustling of cloth. My eyes flew open and I looked around, but saw no one. Glancing at my watch, I saw that it was nearly 9:00pm, almost time to close the library and lock up. I adjusted my clothes and walked back to the desk. My face felt warm, still flushed from my orgasm. Sarah Casey, my graduate student assistant, looked at me quizzically and asked if I was alright. I told her I was fine, just a little out of breath. I told her to sign out and that I would lock up. As she left, I saw her look back over her shoulder at me, wondering. I didn't have time for Sarah; my mind was still on Natalie and the warm wetness between my legs. As I turned out the lights and locked up I fought the urge to take off my clothes, lay down on one of the sofas in the reading room and really let myself go. Instead, I decided to wait until I got home and into a nice warm tub.
My mind replayed all that had happened as I drove home. Natalie was clearly in control of the situation, and if I wanted to keep experiencing the excitement I had felt these two nights, I had to follow her lead. They had been intoxicating, but I wondered where she was leading. Where does one go from semi-public mutual masturbation? The potential both aroused and alarmed me. By the time I pulled into my driveway, I had explored a hundred ideas, but still hadn't a clue where Natalie was taking me.
Opening our kitchen door, I was hit with the odor of pizza and the sounds of bare feet scurrying around in the family room. Julia's new friend, Kate, was spending the night. I'd met her a couple of times and spoken twice with her mother; they both seemed very nice. Then, almost as if conjured up by my thoughts, the two girls appeared in the kitchen doorway, dressed almost identically - men's white cotton tees and baggy athletic shorts. The resemblance, however, stopped right there. Julia was fourteen and Kate a year older. Not quite five feet tall, and petite, Julia's breasts was barely visible through the thin cotton tee and her legs still had some of their young girl spindliness. There wasn't much of the little girl about Kate, though. She was a little taller and a lot more developed than Julie. A whole lot more. In fact, the way she was filling out her tee shirt, I wasn't sure the material could long stand the strain, especially where her nipples threatened to pop through the cloth! Julia and Kate were both pretty and the boys were already starting to come around, though neither of the girls seemed to be interested in them, at least just yet.
Julia was surprised that I was home so early, until I reminded her that the university was on break and the library on shortened hours. She asked me if I wanted some pizza, but I passed - to her immense and apparent relief - and told her I was going take a glass of wine upstairs and soak in the tub. Walking between the girls, I kissed each on the cheek and told them not to stay up too late. They both looked a little guilty and I had the distinct impression that they had been up to something when I got home. But nothing seemed too amiss and I didn't have any desire to do detective work. All I wanted was to get into the tub, sip my wine and let things proceed at their own pace from there.
In my room, I slipped out of my clothes. Unhooking my bra, I stepped out of Natalie's panties and then brought them up to up to my nose. They were still warmly damp, and I inhaled the intoxicating mixture of our odors. Feeling that old, familiar stirring down there, I stepped into the bathroom to turn on the tub. After adding some oils to the water, I went back to the bedroom and opened my "special" drawer to get my favorite vibrator. As soon as I opened it, I knew someone had gone through my drawer. (Just call me an anal old librarian, but I know when my things have been disturbed.) And since we don't have a maid, that someone had to have been Julia. While my favorite vibe was there, albeit in the wrong spot, two other toys and a couple of VHS cassettes weren't. I had a feeling that the missing items had something to do with the guilty looks I'd seen on Julia's and Kate's faces. But, I had the toy I wanted and, anyhow, it was probably time for Julia to have one of her own. I decided to leave the "respect my property" talk for later in the weekend and took my vibe and glass of wine into the bathroom.
I lay down in the tub, my back against my foam rest, and let the warm water close over me. While my fevered brain tried to divine what Natalie might have in mind, my body slowly relaxed, letting the wine and the warm, oiled water work they silent magic. At some point, I put the tip of the vibe on the swollen lips of my pussy, just below, but not touching my clit. I let it buzz away gently. Soon my button was getting hot and starting to throb. Feeling supremely lazy, I let the vibe do most of the work. Moving it up and down my lips, I avoided my clit until it cried out for my full attention. Then, pressing the tip of the toy right alongside it, I let the marvelous machine vibrate me to three or four orgasms of decreasing intensity. I lay in the tub until I was completely spent and ready for bed. Climbing out of the water, I toweled myself dry, brushed my teeth and got into the bed, falling asleep almost immediately.
