I hadn't meant to stay and watch. Honestly. I was only supposed to be dropping off a jacket to my wife's friend, on my way to the gym. Her place wasnt really on the way, but it also wasn't not, you know? And if I'm being honest, she was a great person, and cute to boot, so yeah. Not exactly a chore. 

That said though, dropping off a jacket clearly did not entail standing at a lounge window, staring in slack jawed wonder.

I'd knocked at the front door with no answer, so headed around to the back. I didn't want to leave the jacket at the front door in case it went missing, and it really wasn't unusual to go to the back. It was as I passed that window though, that I looked in. Oh, sweet fate. There was Kara, vacuuming away, bouncing her head along to something I couldn't hear, and wearing nothing but a simple pair of knickers and a bra. 

My head told me to turn away and move, and for a brief moment I did. But the other head took over when I got past the window proper, and turned me back. There she was. Less than 3 meters away from me, and almost completely naked. I'd fantasized about seeing her like this so often that it almost felt like deja vu. But this was so much better. 

The way she was moving around that room, shaking her gorgeous, shapely ass from side to side, with the wonderful jiggle and roll that accompanied it. The way the black fabric covering her wonderful curves moved and re-positioned itself on her body was mesmerizing, and just served to draw closer attention to her breasts, and her belly, and her ass, and that sweet little triangle at the top of her legs. But especially her ass. Wow. With a capital W. 

I must have pictured myself holding that backside dozens of times. Dozens. Kneeling behind her, or with her lying on her belly with me straddling her legs. Cupping it. Rubbing it. Massaging it. Kissing it and licking it. Biting each cheek. Making love to the crease where the top of her thighs met the bottom of her cheeks with my mouth. Worshipping it. And now, there it was. Right. Fucking. There. 

I'll be honest - I was torn, and I felt terrible. Absolutely terrible. Here she was, in the privacy of her own home. She was my wife's friend for God's sake. This was a violation of her privacy. Of their friendship. Of our friendship. And I truly wanted to tear my eyes away. But for the life of me, I couldn't. I was as hard as a fucking rock, and I couldn't move from that spot even if I wanted to. 

I stood still and watched. Leched is probably more appropriate, but I took my time, and drank all of her in. It wasn't long though, before she was finished. She bent down to turn the vacuum off, right leg on the ground, left leg out behind her in a warrior style pose, with her body slightly offset to me. And as her leg came off the ground, I watched the fabric covering her left ass cheek slide smoothly, and tantalizingly, up, and in between her cheeks. I can't say for sure, but I'm pretty sure I moaned. And if I didn't, I absolutely did moan when her foot came back to the ground, and she reached behind herself to hook her finger under the offending fabric, and pull it back out. Before using both hands to gently smooth her knickers down against her shapely bum. Top to bottom, and back up to the top again. Twice. I'm not proud of myself for watching, but watch I did. Wow. 

She grabbed the vacuum and disappeared off down her hallway, and I took a breath. A deep one. And another. And shifted the bulge in my pants. That urge to spend time re-arranging myself was strong, but even in my current disbelieving, booty crazed state, I still knew that was a line that I couldn't cross. With one final breath, I managed to drag myself to the back door where I hung Kara's jacket before turning to go back to the car. 

I slowed down before the window to take another look in. It was equal parts wanting to make sure she wasn't in the lounge and wouldn't know I'd been there, and wanting to make sure she was in there, and wouldn't know I was there. 

I have no idea what I expected, but to my shock and surprise, she was in there, and she clearly knew I was also there. She was standing right there, behind the window. Staring directly at me. Still wearing just a bra and knickers. Smile on her face, and a twinkle in her eyes. Fuck. 

She pointed towards the back door and mouthed 'Thank you', before turning away. For the second time that morning, I wasn't able to move. I don't think it was possible to walk like she did. To saunter like that. Her walk just oozed sex. It was even more Wow. She flowed across that room like liquid fire.

And as she reached the door to the hallway again, she looked back, absolutely sure that I was still there, and slowly hooked her fingers under her knickers at each hip. Teasing me now, she worked her fingers along the hems, following them down to just below each cheek, where she grabbed the fabric, and started to drag her knickers higher and higher, as I stood there watching the fabric slowly disappear, and more and more of those wonderful cheeks came into view. And they truly were wonderful. I stared for what seemed like an eternity, before my eyes flicked up to see Kara still looking at me, still giving me that smile. She winked and gave her knickers one final tug so they disappeared fully between her cheeks, and let the hems go. I could almost hear them flick back against her flesh. With a small wave towards me, she disappeared back down the hall. 

'Christ,' I thought to myself, 'what the fuck was that?' I wasn't sure what it was, or what to believe. Did that actually just happen? I really didn't know, though my throbbing cock suggested that it had. The only thing I really knew for sure was that I had never needed the gym more than I did now. As if leg day wasn't already enough of a struggle.
