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.
