My name is John, named after my father, so my parents had intended to call me Junior, but when my little sister started talking, she couldn’t say it, so she called me JJ for John, Junior. The nickname stuck, and now everyone just knows me as JJ. I have a beautiful sister Deborah, but everybody calls her Deb, and a beautiful cousin who lived next door named Sarah. We live on a very large estate on the lake, and our houses were at the end of a gated, very long, private drive. The three of us were inseparable, having no neighbors to play with. My dad owned all the land on our side of the lake and had built the two houses side by side, one for us, the other for Mom’s little sister, Mae. The two kitchen doors were attached by a covered breezeway, making it easy to go from one house to the other in any weather. We were raised being told Sarah’s father, my aunt’s husband, had died before Sarah was born, and my dad had taken her in and was taking care of all her financial needs. We never questioned why Sarah had the same last name as we did.

Dad is a very successful real estate investor and stockbroker, owning his own business, without partners. In reality, he didn’t have any clients. He spent his time buying property and businesses as well as managing the investments for our family. My mother has her MBA and is the managing director of a small private specialty hospital on the other side of the lake. They specialize in facial reconstruction of people with disfiguring accidents. She will not do plastic surgery for anyone who just wants to look prettier. They just do surgery for people who have been in bad accidents or have serious medical conditions that have disfigured them. My parents own the hospital and have hired the very best surgeons, and my mom runs it. My aunt is an author and has her writing studio overlooking the lake beside the hospital, in the same building as my father. I have never seen a book with her name on it, but three or four times a year, my parents take all of us out to celebrate the completion of another book, and other times to celebrate when one of her books gets an award or makes the best seller list.

Like I said, the three of us kids grew up inseparable. Deb is just under a year younger than I am. I was born on the 3rd of November and Deb was born on the 29th of October, which means I just missed the deadline to start school, while Deb just made it. Sarah was a few days older than Deb with a birthday of October 15th. This means that all three of us started school together, in the same small school, in the same classroom. All through school, we played together, had class together, did homework together, and played sports together. By high school, we specialized in different sports. I played football, making the varsity team my freshman year and starting quarterback by my sophomore year. Deb was on the tennis team and was ranked 16th in the state. She enjoyed tennis but didn’t want to put in the 12 to 16 hours a day to become nationally ranked. My cousin Sarah was on the local swimming and diving team and had been invited to go to the Olympic Training Center, which she had declined. She said the only way she would not make a splash when she entered the water was to have her boobs cut off. She had waited too long for them to grow, so she was not willing to lose them now just for a pretty medal and ribbon. Our parents were very supportive of our activities, never missing a game or a match and encouraging us to maintain our perfect A averages in our studies. With all of our schoolwork and after-school activities, and with us living so far from other teens, we didn’t date. I had gone out with two of my classmates for a total of four dates during my first years in high school, and my sister and cousin had only dated once each. One day I started really looking at the girls and women in our community and school and didn’t see anyone who measured up to my mom, aunt, sister, or cousin. It was more than their beautiful looks. They were smart, nice, happy, and a real joy to be around. Deb and Sarah are both about 5’3” tall, with long blonde hair, and great figures, while I stand 6’1” and 210 pounds. I have spent my time in middle school and so far in high school, lifting weights in our home gym to gain strength, and all three of us run together around the lake daily, in the early morning during the summer and late afternoon in the winter.

Our house is very large. One wing has two bedrooms, one for my parents, and the other for guests, both with private bathrooms. The other wing has two bedrooms for me and Deb, with a large bathroom we share between our rooms. It was a little inconvenient growing up, having to share the bathroom with my sister, and with Sarah when she slept over, which was often. Our bathroom had a door into each bedroom, mine across from the walk-in shower and Deb’s across from the sink and mirror. Growing up, it was not uncommon for the doors to remain open, and the three of us even shared the shower, but when we started hitting puberty, the door was suddenly locked. Often, I had to make a mad dash to the small bathroom off of the kitchen to pee, when I found one of the girls in my bath.

One day, after our morning run, I had flopped down on my bed, waiting my turn to take a shower. The drapes were pulled in my room, making it dark, as I listened to the shower running in my bathroom. I noticed a space under the door of about an inch with the light of the bathroom shining into my room. I got up and laid on the floor to look under the door, but all I could see was one of the girls’ feet in the shower, and I was disappointed. That afternoon, I went into the basement where my mother kept her stained glass tools, found a mirror, cut a section about three inches square, and ground the edges smooth. I hid the small mirror in my nightstand, awaiting the next opportunity to look under the door. I was rewarded that very evening.

Our parents came home at about 6:00 every evening and we ate our dinner between 7:00 and 7:30, with the typical conversation of what happened at work or school that day. More than half the time, we were joined by my Aunt Mae and Sarah, which changed the conversation dynamics, with the adults at one end of the table and the three of us at the other. About once a month, our parents have a business meeting after dinner. My dad handles all the business and investments for both households. From what I have overheard, we own business property all over the county, including retail spaces downtown, farm property out in the country, and everything in between. I don’t know how wealthy we are, but I think we are millionaires several times over.

Our parents have never treated us like rich kids and expected us to pull our weight around the house and treat others as equals. We had a nice home, but we didn’t get all the other things that most rich kids get. I once asked my father if we could get a boat. The next weekend, he led me into the garage to show me a pile of wood and a set of plans. He taught me what I needed to know as we built a sailboat together. When the boat was finished, he bought me a book, “How to Sail.”

That evening, we had cooked out on the back patio wearing our bathing suits, and after cleaning up from dinner had jumped into the pool. At one point, my father, who is also 6’1”, and I played a game of Keep-Away, where we had all the ladies between us, as he and I passed a ball back and forth over their heads, and the ladies jumped up to try to catch it. This had a big effect on my bathing suit, watching four pair of boobs bobbing up and down as the ladies jumped. Deb and Sarah both have large B or small C cups, while my mother and aunt have larger C cups or small D cups, and all the ladies were wearing small string bikinis. At one point, the string around my aunt’s neck came untied, and her beautiful boobs bounced freely for several jumps before she stopped to retie it. My aunt has beautiful tits with very little sag to them at all. The brown areola was about the size of a silver dollar, and her nipples were the size of the end of my little finger and stuck out about a half inch. The game came to a stop shortly after this, and I had to stay in the water until my hard-on diminished. I did notice my father had also been affected and had a rather large chubby when he got out of the pool to make drinks for my mother and aunt. My sister got out to pour lemonade for us kids. I noticed she was staring at my father’s trunks the whole time they were at the outside bar, and when she came back to the pool with our red plastic cups, she brushed her butt against my hard-on underwater. I’m not sure if it was an accident or not. It certainly didn’t help the condition of my dick.

The sun was setting, and it was time for all of us to bathe, put on our pajamas, and get ready for bed. My aunt and Sarah were sleeping over that evening. Thank God, our wing of the house had its own water heater with six of us bathing at the same time. Deb was the first in the shower. I went into my room, locked the door, took out my little mirror, and lay down on the floor by the bathroom door. I carefully slid the mirror halfway under the door and saw Deb’s backside as she was adjusting the water temperature in the shower. When it was hot enough, she dropped her suit on the floor and stepped in. Our shower is about eight feet long and four feet wide, with an opening on the left side and the shower head and wand on the right. In front of the shower is a fog-proof glass wall, and on the wall by the open door is a built-in shower bench. I watched as she stepped under the water and then started shampooing her hair. I loved her tits. They were a smaller version of my aunt’s with the same dark areola and large suckable nipples. She didn’t have a lot of pubic hair, and what she had was thin and blonde. When she turned to face the glass wall, I could make out the slit of her pussy very clearly. The lips didn’t hang down, and her clit was completely hidden, not like some of the ladies I had seen on the internet porn sites I had visited. This was the first real nude female I had ever seen, and I thought she was perfect. I put the mirror on the floor and quickly wiggled out of my Speedo bathing suit before assuming the position again. It didn’t take her long to rinse the chlorine out of her hair, so she took the wand off of the wall and sat down on the shower bench facing me. She scooted to the front edge of the seat, leaned back against the cold tiled wall, and spread her legs. Taking the shower wand, she adjusted it to a solid stream and started spraying between her legs. I watched as the water jet moved from her clit to her pussy and back again, while her other hand was pinching her nipple between two fingers. Something had her really turned on. In only about five minutes, I watched her knees part further apart, the wand moving faster up and down, and her head leaning back. She suddenly looked wide-eyed across the bathroom in the full-length mirror and gasped. Her stomach muscles started rippling, and she stopped breathing. She was having a massive orgasm that lasted at least two full minutes before she started relaxing. She just sat there, gasping for breath, with the occasional aftershock for about five minutes before a final rinse, and she stepped out of the shower on weak knees to dry off.

I had rolled slightly to my side so that I could reach my dick and relieved some pressure while I watched my sister masturbate, and had blown my load onto the floor when she started cumming. Wrapped in her towel, she opened her door and passed Sarah on the way in. My dick started getting hard again, knowing I was going to watch my cousin bath, as well. Like Deb, Sarah rinsed her hair and body quickly before standing by the door, looking at herself in the mirror, and directing the shower wand to her pussy. She raised her left foot and put it up on the shower seat, holding the wand in her left hand while she used the finger of her right hand to strum over her clit. It didn’t take her long before her right hand became a blur. Like my sister, she was watching herself in the full-length mirror across the room. Sarah was not as quiet as my sister when she came. She started whispering, yes, yes, yes, before her stomach muscles started contracting. I watched as her legs became too weak to stand on and she sat down on the seat and relaxed after her orgasm. I had added a second load of cum to the puddle already on the wooden floor beside me and was exhausted. When she stepped out of the shower to wrap herself in a towel, I got up off of the floor, got a handful of tissues from the bedside table, cleaned up my mess, and fell onto my bed. I had intended to take a shower, but I fell asleep before I could even pull the covers back or put on my sleep shorts.

All summer long, this became my pattern. After our morning run, I would watch my sister take her shower. She seemed to masturbate three or four times a week, and Sarah masturbated almost every time she showered at our house. At the end of the summer, Deb brought it up a notch. She had ordered a pink rubber vibrator that was waterproof. I watched as she carefully lubed it with baby oil and pushed it into her pussy before turning the shower wand onto her clit. She slowly pushed about four or five inches of the pink vibrator in and out of her pussy, building up speed slowly. In the end, she just dropped the wand and attacked her clit with the fingers of the other hand, as she pumped the vibrator in and out. She exploded in a massive orgasm and collapsed back against the wall, leaving the vibrator turned off and neglected. I watched as the pink tube eased itself out of her pussy and fell to the shower floor. Her vibrator looked to be about seven inches long and over an inch across the larger head. It looked a lot like my dick, perhaps a little thinner than mine. This thought went from my mind to my dick in an instant. There was no barrier inside her pussy, and my dick would fit.

Soon after school started, I had come in from football practice, covered in mud and sweat, desperately needing a shower. I stripped in my room and walked nude into the bathroom. I noticed my sister’s bathroom door was open an inch or so, and decided not to shut and lock it, as I normally did. I had been watching my sister and cousin masturbate for months, and I wondered if she would like to watch me jerk off. When I stepped under the shower head, mud went flying in all directions, and I watched the reddish-brown water wash down the drain. After washing my wavy blond hair and running a shower loofah over my body, I sat down on the shower seat. I had taken my small bottle of baby oil with me to the shower. I put some on both hands and rubbed it on my dick and across my balls and slowly started pulling on my dick. It didn’t take long for me to achieve full size, about six and a half inches. I wrapped my whole hand around it and started pumping, allowing the head to slide just inside my hand before going in the other direction. With my left hand, I held my balls, slowly kneading them with my fingers, even running one finger back to my butthole. I was sitting on the front edge of the shower bench with my knees far apart, leaning back against the back wall, watching myself in the mirror, just like Deb did. I was really getting into it, when I saw a shadow pass over the crack in the door through the mirror. I kept my eyes on my own reflection, only watching the shadow with my side vision. The shadow became an eye, as my sister moved closer to the door. The door slid open another inch. I could see her push her shorts down and watched as her hand started moving over her pussy. My dick grew bigger than it had ever been, adding both length and girth, and it was as hard as steel. I felt my balls start to tighten up and slowly become walnuts as I got close to blasting. I tried to hold off for as long as I could, but with the excitement of being watched and knowing she was masturbating, too, my balls erupted with a geyser of cum shooting up my chest almost to my face. I shot at least eight volleys, each a little weaker, until finally the cum just washed over my fist and onto my balls. I had forced myself not to close my eyes completely, as I normally did, and peeked through my eyelashes to see what my sister would do. Her mouth had formed an O, and she had stopped breathing, as the fingers of her right hand had strummed her clit to a blur. When I opened my eyes again, my sister was gone. I washed off the baby oil, dried off, and went to my room with a smile on my face.

I normally jerk off at least once a day, and as many as three times a day. Now, I made it a rule to leave my sister’s bathroom door open a crack at least once a week and let her watch me. It was Christmas vacation when I had the opportunity to jerk off in front of Sarah. Our parents were all at work, and the three of us had just come in from our afternoon run around the lake. I called dibs on the shower first and rushed in to have some fun, taking my baby oil with me. Knowing Deb and Sarah had not gotten to their bedroom yet, I opened their door just a crack before turning on the water to warm it up. I rinsed off the sweat and warmed up my hands and feet from the run before assuming the position on the bench. Out of the corner of my eye, I watched as the door was slowly pushed open about two inches, and two sets of eyes were glued to my dick and balls. I put on the best show possible and lasted as long as I could, but still, I didn’t last as long as I wanted to with both of them watching. I again blew my load, this time with it landing out of the shower onto the bathroom floor with my first three blasts, before finishing the last three blasts on the shower floor. I finished with the last of my cum pumping out of the end of my dick and running down my hand between my fingers. This time, I was very verbal as I jacked off, moaning as I got close and even muttered their names as I came to let them know I was thinking about them while I jerked off, and hoped it didn’t wear them out too much.

When I left the bathroom, I called out to them that the bath was theirs and went into my room. I heard the click of the lock on my door when they claimed the shower. I took my mirror and looked under the door. Before they got into the shower, both girls scooped up some of my forgotten cum off of the tile floor and put it to their lips to taste it. They got in the shower together, and I watched as they washed each other’s long hair and backs. Then they turned to face each other and started washing each other’s fronts, taking longer than necessary to wash their perky tits and pinch their nipples. Both girls were in the bathroom and the shower together. When they reached each other’s pussies, I watched as their feet took a wider stance and their knees spread wide to make their pussies more accessible to the other’s fingers. I had watched the previous week when Deb had shaved her pussy completely bare before she masturbated. I heard Sarah ask her if my sister would help shave her pussy. We had two razors in our shower, a blue one for me to shave my face, and a pink one for my sister to shave her legs. Deb took the shaving gel and lathered up Sarah from her cute little back door to her navel, as she sat on the edge of the shower seat with her legs spread far apart. I could see past Deb’s right shoulder as she took the pink razor and started shaving around Sarah’s asshole and finished over her pussy. She very carefully saved her pussy slit before taking the wand and washing all the gel off. She stepped out of the shower and picked up her pink vibrator off of the countertop and got back on her knees again between Sarah’s legs. I watched as she turned the wand to a pulsating stream and directed it to Sarah’s clit, as she slowly inserted the pink tube into her vagina. Sarah closed her eyes and started breathing like she had just run 10 miles. Sarah leaned her head back against the cold tile wall and closed her eyes with a look of ecstasy on her face. Deb asked her something that I couldn’t make out and Sarah nodded her head. Deb put the shower wand on the floor, pushed our cousin’s knees farther apart, leaned forward, and started licking her pussy as she worked the lifelike dildo in and out of her hole faster. It only took a couple of minutes for Sarah to explode. As she slowly came down from her orgasm, Deb eased the vibrator out of her pussy, rinsed her clean, then leaned forward and kissed Sarah’s pussy. It was obvious this was not the first time my sister and my cousin had played around. I heard Sarah say, “My turn,” and they swapped places. The shower wand was forgotten, as Sarah did a nose dive right into Deb’s pussy. I could clearly hear the slurping even over the sound of the shower wand. Deb was obviously very turned on from eating Sarah to orgasm and started cumming quickly, holding Sarah by the hair to keep her mouth in the right place. She orgasmed violently, lifting her legs in the air and spread wide apart. All this time, I was on my knees on my side of the door with my ass in the air, watching them and pulling on my dick. I had cum in the shower and left two more loads on the floor of my bedroom before they were done. I was exhausted, and my dick was starting to get raw.

I continued to spy on my sister in the shower, as well as my cousin, whenever she was over, and about once a week, I arranged for them to watch me jerk off. One day, while Deb was watching me, I took the saving gel and lathered up my balls and pubic area. I had never had a lot of hair down there, but sometimes it did get in the way while I jerked off. I started saving by my butthole, then up either side of my balls. I carefully lifted my dick, pulling the skin on my nut sac tight, and carefully removed the hair. I then scraped all the hair off from my dick to my navel. I shaved this area twice, getting rid of all the stubble, before rinsing the area of the gel residue. I had been so single-minded at my task, being careful not to cut myself, that I had not looked at the crack in the door, where my sister was watching, and my dick was not fully erect. As soon as I was finished, I smeared baby oil over the entire area and started pumping my shaft. It felt so good, not having to deal with pulling an occasional hair, and my balls were ultra-sensitive, so it didn’t take long to start shooting cum everywhere. With the first squirt, I heard a moan that was not mine. My sister had brought herself to orgasm at the same time I had.

One weekend, while Sarah and my aunt were staying with us, I slipped into the dark bathroom after the girls had showered, without masturbating, and gone to bed. I had a thought, that if my door had a large crack under it, perhaps my sister’s bedroom door had a similar crack, and it did. I took my mirror and took a quick peek into their room. From the angle of the floor up to the bed, I didn’t have a very good sightline, but I could see enough. The girls were in the classic 69 position, with Sarah on top. I couldn’t see well with the dim closet light and their position, but they were having fun. I watched for several minutes until by the sounds of their moans, I knew they had both orgasmed together. Sarah turned around, kissed Deb, snuggled up beside her, and went to sleep.

One day in the spring, after Deb, Sarah, and I arrived home from school, I went into the shower, leaving their door open a crack. I took my shower, shaved my pubic region, and had a nice hard-on. I looked into the mirror and knew they were both watching me, but I didn’t jack off. I turned the bathroom light off and went into my room; but as I did, I intentionally left my bathroom door open a crack. I lay across my bed with the light from the window shining across my body. I had worked out the exact position before I had taken my shower by placing a mirror on my dresser, so I could see the door opening, but the girls could only see me from the chest down. I slowly started jerking off. Several minutes passed before I heard one of the girls come into the bathroom. I looked in the mirror and saw Sarah peeping in on me. Then, I heard her scurry from the bathroom to get my sister, and a moment later, they were both looking at me. Because they could not see my head, they assumed I could not see them, so they pushed the door open another two inches. Lying on my back, they had a clear view of me slowly jacking off with my right hand and rubbing my balls with my left hand, and from just four feet away, not from across the room. Sarah got onto her knees while Deb stood over her and watched me jerking off. I couldn’t see well, but I could see well enough that they both had their hands in their panties, rubbing their clits. I think they both had an orgasm when I did. I aimed my dick straight up to see how high my cum would go.

Once I had cleaned up and slipped on my sleep shorts, I slipped into the bathroom to look under their door. They were both naked, sitting on the side of the bed and playing with themselves while they discussed what they had seen. Deb surprised me when she said, “I want to suck his dick. I’ve heard other girls at school talk about giving blow jobs, and I want to suck on JJ’s dick until he cums in my mouth. One of these nights, I’m going into his room when he is asleep and suck him off.”

Sarah shocked me more when she agreed, “Sandy talks about giving blow jobs all the time while in the showers after diving practice. Now, she is dating one of the guys on the swimming team, and he shaves like JJ does. Sandy says it is even better when the guy is cleanly shaven. All the other girls on the team call her a slut. She’s not a virgin and admits that she loves sex, but she especially loves giving blow jobs. If you give JJ a blow job, I want to join you.”

Deb got very quiet for a moment and finally spoke again, just above a whisper, “Do you know Jacky on the tennis team?” Sarah said she did. “She told me a secret last summer. She and her older brother Bob have been having sex ever since she was a freshman. She loves to give him a blow job before he fucks her. People call her the Ice Queen because she’s a senior and doesn’t date anyone. She told me her brother is going to State this year, and she is going to move in with him next fall when she goes to college.”

“Wouldn’t it be great if the three of us could live together when we go to college in a couple of years? We could have sex all the time.”

“Wow,” Sarah whispered back. “I would love to have JJ take my virginity. I want to feel him inside of me and shoot me full of his cum.”

“Yeah, me, too,” Deb whispered back. “I’ll eat his cum out of you while he does me doggy style.”

Wow, both of the girls want to give me a blow job and have me take their virginity. I am normally a very heavy sleeper, but from now on, I’m going to sleep with one eye open, just in case, and as of tonight, I will start sleeping nude. Two weeks later, after I had showered and shaved, with the door to Deb’s bedroom cracked open and her watching, I had a nice hard-on and stroked it a few times, but I didn’t jerk off. It was late on a Friday night, and I just went to bed, leaving the closet light on, my bedroom door locked and the bathroom door open. I woke up when I heard Deb whisper, “JJ, are you awake?” I was sleeping on my back under a light sheet, without any sleep shorts on. My head was turned away from the bathroom, and I pretended to be sound asleep. I could hear Deb move closer to the bed, and again, she whispered, “JJ, are you awake?” I remained still. I felt the sheet carefully being pulled down off of my stomach, slowly revealing my nudity. When the sheets were down to my knees, I heard her one more time, “JJ, are you awake?” She touched my dick with her fingers and lifted it from my abdomen. I started getting hard as soon as I heard her voice. She sat down on the side of the bed as she kept playing with it. She used her right hand on my dick, and she started playing with my balls with her left, rolling them in her hand, just exploring. When I was fully upright, I felt her lean forward and plant a kiss on the end of my dick, then put out her tongue and lick the pre cum off the top of the head and taste it. I heard her quietly say, “Yum.” She slipped the head of my dick into her mouth, carefully covering her teeth, and began moving her mouth up and down on my dick. My dick continued to harden until I passed my previous record in both length and girth, as my sister continued to suck on the head and move her hand up and down on my shaft, while she rubbed my balls. She had learned just how I liked it by watching me jerk off in the shower. I stirred a little, like I was waking up, and she froze as I separated my legs more and bent at the knee, giving her more access, and acted like I was still asleep. She didn’t move for a minute or so to make sure I was still out of it, but she never took my dick out of her mouth. Slowly, she started moving again. She must have been watching blow jobs on the internet, because I knew this was her first time, and she was doing a great job, not that I was a judge, since it was my first, also. There was a nice amount of suction, and her tongue was playing just under the rim. I couldn’t take much of this action and blew a big load into her mouth. She blocked it with her tongue so that it didn’t go down her throat and was able to keep most of it in her mouth. I felt her swallow and then continue to clean off my dick as it started to soften up. She stood up and whispered, “Thank you,” and tip-toed back through the bathroom door. My dick felt a little wet as it lay up on my stomach, and I was totally relaxed. The last thought that went through my mind before I drifted back to sleep was, “I wonder if Deb is masturbating right now.”
