I just spied on my sister. I had just gotten home and she was in the shower. I hadn't done it in so long but I haven't had a girlfriend for 4 months and everyone was asleep and it was dark (for the nice fishbowl effect) so I decided to go for it.
It's usually pretty simple because on the floor at the entrance to her bathroom there's a white piece of marble dividing the carpet from the tile and the's sufficiently reflective enough to view the shower on the other side of the bathroom. So that was pretty nice, nothing special. Shower stopped, got down on hands and knees, looked under the door, and saw her open the shower curtain and dry herself off. Pretty routine, the view is kinda blurry, can't see the crotch well because of shadows and tits were still perky.
But this time I got so much more. When I saw her wrap a towel around herself and head for the door I sidled into my room and out of view. She exited the bathroom and headed into her room but only tapped the door. It was still left very ajar, she didn't know I was home yet. So I took this opportunity.
I hung half in and half out of my room, looking into hers. For a while she was out of view, I could hear sounds from her closet. Then all of a sudden she stepped into view and laid her clothes on her bed. And then she dropped her towel.
She has a fairly thin, tan-ish body. Not super thin, curvy. Her tits are maybe C's, perky, with darker tan nipples. I watched them jiggle as she dried her hair off a little more. Then she turned slightly and I got a full view of her pussy. Smallish lips; she was shaven but not bare, probably shaved 5 or 6 days ago. At this point I was vigorously massaging the bulge in my pants.
I then watched her a little bit more as she snapped her bra on and pulled black panties on. After all the goodies were covered I took that as my queue to slink away before anything bad happened. I hid in the darkened corner of my room, waited maybe 5 more minutes until she left her room, t-shirt and jeans on with towel around her hair, back to her bathroom (presumably to do make-up,) and then silently darted down the stairs to the basement to type this. I have yet to whack-off; I imagine these images in my head are going to make the next few minutes of my life very enjoyable.
