I grabbed a chipped glass from my bedside table, and headed for the bathroom sink. I'd been drinking at a party in a flat downstairs from mine, and I knew that whether I'd had twelve beers or two I'd definitely have a hangover. The drink of water wouldn't stop that, but it might keep it from being too terrible.
As I filled the glass, I glanced out the window and downward, to see what was going on in the first-floor flat Katharine occupied next door. She'd been partying downstairs too, and I knew well that she never bothered pulling her blinds down. She was careful to dress and undress in a room that was out of sight of the windows, but beyond that she just didn't care β so I've had plenty of chances to see her loiter around her bedroom in only a bathrobe. She has two robes, one green and one blue, which complement her deep tan wonderfully. They're both cut the same way, showing her legs to a point well up the thigh and often slack enough to show the inner curves of her breasts.
I still enjoy watching her, of course β she's a very sexy woman β but she's careful enough that I haven't seen anything new in months, so I don't always do more than glance at her window. When I'm especially aroused, I stand in this doorway and stare, stroking my erection and thrilling at my voyeurism, but tonight I doubted I needed Katharine's stimulation. One of the couples at the party had been very frisky, and the memory of their fooling around in the corner was arousing enough β he'd been openly caressing the sensitive underside of her breast, and often tested to see how far up her skirt she'd allow him. I think he did reach her knickers once; her fingers had clutched his shoulder and her eyes had closed before she moved his hand, and it had been plain that she was very turned on. Actually, from the blush on her cheeks and her chest I was surprised she'd had enough restraint to stop him from continuing.
That is, I didn't think I needed Katharineβ¦until I looked into her bedroom. I sipped my water as I stared at something unusual. Tonight, she would be having a guest; she was dabbing perfume on herself right now, and the reason I knew she was staying in and not just going out again was that she wasn't dressed to leave her room. The silken pyjamas she wore covered even less than her robes did. Two small buttons, sitting at the very edge of the fabric mere centimetres below her breasts, held the top together, and purposefully exposed all that cleavage that the robes sometimes showed accidentally. Tiny shorts sat low on her hips, leaving another foot of skin in the open, including several inches below her navel; her pussy couldn't have been far from the waistline.
The inch of skin she had showed at the party had been tantalizing enough; I'd looked at it often, and whenever I walked behind her I excused myself while tapping the small of her back where it was exposed. My excuse for touching her was to get her attention, but the warmth of her skin was the real attraction. Now, as I watched her brush her stomach lightly, as if she was daydreaming, I wasn't only tantalised, I was as hard as I'd ever been. My cock had shot to full size inside my boxers, and had already left a dot of pre-cum on their fabric.
Katharine, still waiting for her guest, was obviously also aroused. She was antsier than I'd ever seen her at this time of night, walking small circles in her room and letting her hands wander wherever they felt best. Her nipples showed through her top, though from what I'd seen she hadn't touched them yet. Her mouth was open a little, and I imagined her breath was short. She ran one hand through her hair, then lightly rubbed an earlobe; as that hand lingered there, the other brushed her inner thigh then sprang up to skim under her top and spend a moment caressing the sides of a breast. She pinched her nipple, licked her lips β oh, I loved that! β and closed her eyes, and I wondered if she would be so careless as to continue on and cum in full view. I closed my eyes for a moment and pictured her ecstasy, savoring the image. In my mind, her eyes were tightly shut, her mouth was wide open in a loud moan, and her hand had dipped deep into her pyjamas as she shuddered in orgasm.
