I’m a twenty-four-year-old grad student and my sister Rose is just over 18. We both live at home with mom and stepdad in a really big and really old 2-family house. Rose and I share the upstairs unit which consists of 2 bedrooms, a living room area and a full kitchen and bath. There’s a 2nd doorway between Rose’s room and the bath. It’s a door we never actually use; in fact it was painted shut long before either of us were even born. The door itself is original to the house, with an antique glass doorknob and big old keyhole. Thank god it never occurred to my sister to cover up that keyhole…
About three years ago, my stepdad evicted the tenants they rented the upstairs apartment to so I might have ‘a place of my own’ to live after college. Well, that place of my own never came to be; my little sister Rose had campaigned fiercely for half the space and beat my parents down. I didn’t have too much of a problem with it; Rose and I got along really well and had lived together growing up, so…we laid down some ground rules when I moved back home and we’ve shared the place ever since.
I never noticed the keyhole in the door between her room and the bathroom; I wasn’t living at home when my dad had the upstairs renovated or when Rose moved her stuff up.
She had a big queen bed with a large wooden headboard that almost hid the fact that there was a door there at all. The bathroom side of the door always had bathrobes, towels, etc hanging on clothes hooks that covered the doorknob (yeah, sharing a bathroom with my sister was sometimes a bit of a drag); I guess I knew it was there but it never really registered. Until one day she asked me to help re-arrange the furniture in her room. I bitched and moaned about it but really I was happy to help. We moved her bed up against the opposite wall from where it used to be; there was the door! Still, I really didn’t give it a second thought. I hung up a full length mirror on it for her; she said the door looked stupid there, and the mirror mostly hid the door for a second time. But not that keyhole.
Just a few nights after that, I went to the bathroom to take a shower. I opened the bathroom door and before I could flip on the light switch I noticed a laser-thin beam of light entering the darkened bathroom from the other bathroom door–from my sister’s room. I stopped dead in my tracks. Hey…I thought to myself. I wonder…I left the light off and walked over to the keyhole. Bending down, I placed my eye directly over the small opening. I felt a shock of devilish delight as I scanned the entirety of my sister’s bed, directly facing me across the room. Rosie wasn’t in it, but I could see all four corners, all of her stuffed animals and the end table in the corner.
Wicked thoughts entered my head and I found myself squeezing my dick through the towel I was wearing. ‘C’mon, Pete; you wouldn’t peep in on your own sister, would you?’ I asked myself. ‘You know Pete,’ I replied, ‘I think I just might!’ Before I could continue with this inner debate, Rose crossed in front of the mirror and quickly out of sight again. My heart stopped and I couldn’t breathe. Then, once again, she entered my line of sight. Well, the inner debate was over. The verdict was in: I was peeping on my sister!
No question: Rosie was a hottie. She was wearing white cotton panties, a white tank top and was clearly bra-less. That had never been a big deal; her generous 36-C boobs were something I always teased her about when we were younger, but I saw her in extra-casual mode around the place all the time so seeing her bra-less was nothing new. But there was something about seeing her this way, through the keyhole…I couldn’t take my eyes off of her gorgeous cans. She grabbed a hair brush from her make up table and began brushing out her long blonde-ish hair in the mirror I had hung on the door. I was terrified that I might be found out…she was about 5 feet away! She would see me staring! She would know! But no. She had no clue. She just kept brushing her hair with a distant look on her face.
When she gathered her hair back to pin it up for the night, it looked as though her tits were just inches in front of my face. After years of keeping my brotherly cool, the man in me could finally stare right at those beauties and not catch hell. My hand went for my cock again. I looked down across her flat, tanned teen-aged stomach and found a new sight to obsess on: the panties that covered her pretty little cunt They looked so soft and clean and barely concealed the treasure within. I could make out the shape of her pussy lips and her inner thighs were flawless. When she sat down on the edge of her bed to click on the tv, I watched her titties jiggle and continued jerking my cock. She spun around and sat cross legged on her bed facing the television, and I scanned her long, lean, 18 year-old legs as they passed my view. She was completely oblivious to the fact that someone was watching her every move. I was furiously working my dick. WOW, I thought. What have you stumbled across here, dude! I turned on the shower and got in. Jerking off furiously, I tried for a second to think of anything other than my sister’s beautiful tits, luscious legs and the crotch of those panties. I failed and went with it.
In the months that followed, I found my self slowly and subtly changing my schedule so that I might be in the bathroom when Rose was in her bedroom, wether early in the morning or later at night; even during the day if she were just hanging out. I had to be careful, though–this was a goldmine I did not want to ruin. I suppose I felt guilty about it from time to time when thinking about it too much, but the intense boners I got when gazing through that keyhole erased all sense of shame from my mind.
Most of the time I saw nothing much–Rosie sleeping, completely obscured by blankets; Rosie talking on the phone with her new boyfriend Kevin; Rosie watching TV or doing homework. But I got a charge out of these harmless scenes, too. My sister’s body continued to invade my thoughts. I wasn’t dating anyone and found that whenever I masturbated, the fantasy woman was always her. I tried to think of former conquests, but I couldn’t. In my dreams it was Rose fucking me. Rose sucking me. Rose beating me off. It got slightly difficult just to interact with her at home as we normally would; memories of the secret forbidden shows played over and over in my mind. It would soon get worse.
Many more sneak-peeks sessions came and went; still most of them consisted of really mundane scenes of TV watching, homework, or an empty bed. But I was obsessed. My first big treat came in the second month. One Friday night, my parents were out of town, and I was going out with some friends. Rosie had invited Kevin over to watch a movie. She asked me when I might be getting home, and I was no fool; I knew that that meant there might be a little hanky panky going on that night. This was too good an opportunity to miss. I checked out with my friends a little early and headed home.
As I crept into our apartment, the tv in the living room was all snow; I saw a half eaten bowl of chips on the couch, some empty beer bottles, a plastic rental-video box…and one of Rose’s blouses was on the floor. Jackpot! I pounced into the bathroom. Looking through the hole, I couldn’t believe my eyes. There, right before my eyes, were Rose and Kevin, petting like mad! Her stereo was on and I couldn’t hear the two of them but they were really going at it. Rose’s bra was hanging off one shoulder, one soft round tit clenched in Kevin’s hand. He was sucking hard on her nipple; her eyes were closed and head tilted back. With her left hand, Rose was jerking Kevin off; his pants were pushed down to about his knees and he was hard as a rock. He was pressing into the crotch of Rose’s still-buttoned jeans with his free hand. [read more](https://realsexstoriesx.blogspot.com/2021/05/through-keyhole-pete-peeps-on-sexy.html)
