When this story occurred I was about 18, my step-sister, the object of my observations, was a freshman in college. I was just starting to explore my own sexuality, and the nice round B sized cups of my sister were a good place to start. She was about 5' 2", dirty blond hair; blue eyes and a petite but rounded body. Not big enough to be fat, but a little bit of meat on her so not to be boney, so that when you really start to fuck her, you have a little bit of padding to hit, and the slapping of your ass on her's is a loud smack, smack smack. But I digress...
This was the first time I saw her in the shower. I had seen her change before, in her room, from under her bed. The bed was not quite tall enough, it was only 5 inches high with a sheer bed skirt, just enough to obscure the boxes, or people under the bed. I couldn't quite fit under there with enough space to see my sister's mirror, in front of which she changed. Well, the whole point was to see her in front of the mirror, as when she came out of the shower she was only in a short little towel, barely covering that cute little 19 year old ass of hers. From under the bed, you could barely make out though the sheer bed skirt her ass and her awesome tits. But not her pussy, you could never see her pussy because every time she would come out of the shower, walk into her room, drop her towel, and then bam panties. At first I was amazed by only her tits, but the urge to see her pussy became immeasurable.
My sister's tits were the best thing I had ever seen. They are basically big B's, but as we all know there is a range of great tits. There are the ones that barely make the B level, only to satisfy the girls that they aren't an A, and there are the perfectly formed B sized tits that are a little bit bigger then your palm, squeeze through your fingers as you rub them, barely squeezing though. My sister's were the larger of the two, but with tiny nipples. Little pink nipples. Oh, these were the greatest thing ever, but no pussy.
At this point I had my 'under the bed routine' down. It was simple. I would hear my older freshman sister start the water next to my room and then it was time to go to work. At this time I knew she was stripping down, taking off the bras and panties I had already come in. At this point I had made a point of jerking off in all of her underwear, stealing it from the clean laundry, and coming in the crotch so that my come constantly resided next to her cunt. I figured it was only a little crispy, usually wore our so that her juices were constantly intermingling with my sperm. So as I thought of her little pussy being striped of my come filled panties, I would grab the four blocks of 2" by 6" wood I had stashed, and carefully and intentionally cut, from inside my desk.
Then I would sneak into her room as she showered. The plan was basically to come in, put a block under each leg, sneak under her bed, then watch her undress when she cam out of the shower. Well, there were complications. First, the extra 1.5" of room neither creates a lot of room nor allows for extra visibility from under the bed. As much as you would like to, and god knows I did, stick your head out and take a look around, you have to stay behind the little sheer bed skirt, and see what you could see.
Well, at first this looked like looking out from under her bed and looking at her door, which was to right of her dresser. The dresser had her bras and panties in it, the frequent target of my raids. It was also where she changed. So the plan involved looking from under the bed towards the dresser and the mirror. Here is where I saw my sister sizing herself up, examining her beautiful tits, playing with them casually, and then putting on a bra. Of course after the bra went on, the interest decreased but the commitment could not.
I was now under a bed, not able to go to the bathroom, sneeze, and drink or do anything else. I watched my sister try on cloths, different bras, tight black pants, jeans, or skirts. I was in a divine hell watching my sister change, nude, barely clad, and listen to her talk to her girlfriends about her most intimate secrets. You were trapped and this meant that the 1-2 minutes of greatness left thirty to forty minutes of hiding and waiting. It was at the tail end of the last of under-bed expeditions that I decided I had to step it up a level.
My sister had come out of the shower and I was under her bed. Sneaking and looking around but nothing. From my position I couldn't see shit. I would hear noises, but nothing. She was to the right of the bed, outside of my view because when you were under the short bed you couldn't look either way because your head was trapped either to the left or right because the low height of the bed made it impossible to turn without pushing up the bed. So I was trapped looking left towards the mirror in front of which my sister would display herself, but there was obviously something, at least a lot of noise to my right where I couldn't see. So I was left to make a decision, either turn my head and see what was to my right and squeeze my head into the bed as it rotates, possibly disturbing the bed, my sister, and giving away my position. Or, I can stay where I am and miss the action.
You know which one I chose. I looked right risking her possibly feeling my head from under the mattress (It turns out 'actually felt' as my sister has later told me…). What I saw was hot, mysterious and inaccessible. Her legs were spread apart and moving a little bit. Moving a little bit, more of a shaking, and I could feel her wiggling above me on the mattress. She kept moving, squiggling, and then the muffled squealing and moaning started. I knew she was masturbating, fingering herself, pleasuring herself. Something I'd heard of but never was able to see. Also, the way my head was facing, the complete opposite of the direction I was looking, I couldn't relive myself by jerking off and simply had to sit there. So I sat there, tortured, under her bed as my sister fingered herself furiously on her bed, squealing, moaning, and wiggling above me with her thrashing transferring itself through the mattress into my trapped body that could not be relived because I was trapped. As my sister's fingers finally brought her to orgasm directly above me, she moaned and finally came in the empty house, eventually getting dressed in front of her mirror where I would have been able to see here if I'd still been turning left. At this point I didn't care, I needed to see my sister's pussy.
So I turned to the random piece of military paraphernalia from my father's career that explained various surveillance techniques. The one I selected was developed by East Germany based on the Kodak Pinhole Camera. The camera that Kodak invented is a pinhole, with a makeshift shutter, and film behind it in a completely black box. I only stole the first part, but after seeing what I had seen I wished (still to this day) that I'd had the film and not my eye in it. Regardless, the East Germans were notorious for spying on each other (1 in 6 of the population was employed in some way by the Stazi) and developed interesting and cheap ways to do so. One of those took advantage of the construction of drywall, which is that there is paper on both sides with a composite in the middle. The method is to remove one side of the drywall, slowly and silently remove the composite between the layers, leaving only the paper on the interior of the wall.
