Sister-Lover Seduction: A Forbidden Family Affair

This story is fictional; any resemblance to real life events is coincidence.
--------------------------------------------------------------

Yesterday my mother and I came up with a plan for me to seduce my brother, Ryan. She believed it was safer for us to discover and explore with each other, than with someone else. She convinced me that the attraction I felt towards my brother was normal and acting on the attraction was socially unacceptable, but perfectly ok behind closed doors.

I had spent most of the morning in my room cleaning and thinking about all the things my mother suggested I do to find out if Ryan is interested in me. I headed down stairs and found my mom watching TV in the living room, dad and Ryan where outside mowing the grass. When my mother saw me come in she smiled and waved me over.

"I talked to your father last night about our plan. Not only was he onboard with the idea, but he got extremely hard as I discussed the details. Our conversation lead to some really good sex. Our door was closed but, I hope we didn't wake you."

"I didn't hear anything, I was pretty tired when I turned in."

"So shall we go shopping today?" I felt my nipples harden. Glancing down at my chest my mother said, "I'll take that as a yes." I smiled as she grabbed her keys.

While shopping I didn't pick up anything too racy. I mostly stuck to cotton, silk and lace; a few bras with matching thongs, hiphuggers, and Cheekies. I didn't want to be too obvious as to what I was doing by going with leather or crotch-less. I also picked up a bikini, and I have to admit, it looked really good on me. It fit my body perfectly and it hugged my curves well. I picked up a few short skirts that would be easy for me to give him a peek without being obvious, and a few low cut tops that should allow just a hint of my new lacey bras to be seen when looking closely.

My mother commented that he didn't have a chance. She indicated that if he wasn't interested before, after our little shopping trip, he would be now. We also picked up some flavored lubricant after my mom said, "You never know when you might need
it." She suggested keeping a bottle in my room and a small bottle in the upstairs bathroom.

When we got home I went up to my room to change. Even though Ryan was outside I left my door slightly open to start getting in the habit. I came down and sat on the couch in front of the TV. Behind the TV was a large window and patio door out to the backyard and pool. I could see Ryan still working outside, but he had his shirt off. He had a great chest and nice abs. He was slightly sweaty from all the work which gave him a sexy shine. I sat in my skirt with my legs slightly apart just in case he happened to look inside. I sat and watch him for a while acting like I was watching the TV. The rest of the evening I looked for opportunities to give him a peek up my skirt, without doing so every time I sat down. I saw from the corner of my eye a few times when he would notice he could see up my skirt. I even noticed him trying to look a few times I wasn't trying to give him a view. This was definitely going to be fun.

I decided to take a shower that evening and tried to time it so he would head upstairs after me and walk past the bathroom. I left the door open slightly, but the hall was too dark for me to see if he stopped to watch me, or even if he walked past at all. After my shower I noticed that I should be able to see my room from the cracked door, so if I left my door open I should be able to see light coming from the room. I still wouldn't be able to see who was at the door, but I should be able to tell if someone was there since they would block the light behind them.

This teasing went on for a few weeks, and I could definitely tell he was interested. I was also enjoying the attention. When "the boys" were out of the room my mom and I would confirm with each other that he was definitely taking an interest and sneaking glances. The light in my room worked great when I was taking a shower and I found him delaying going upstairs or down till I was taking a shower or changing my cloths. I also saw him looking at my chest when my nipples would get hard, which of course made them harden often around him. I often saw him get hard when noticing my nipples or getting a shot up my skirt. I found out that I could hear him come up the stairs and walk past my room if I paid attention. I got very excited each time I heard him pause on the way past to watch me undress. I started wearing shirts that left my stomach exposed and micro shorts to bed or long t-shirts that just barely covered my panties rather than the loose shirts and pajama bottoms.

One night he went to bed earlier than me which was a little disappointing. I headed up to my room and out of habit left my door slightly open. As I was changing into a short shirt and shorts I heard him come out of his room and stop at my door. After I finished changing he headed back into his room I waited a minute or two and as quietly as I could crept over to his bedroom door. I put my ear against the door and could hear a slapping sound and a soft grunt here and there. I was already damp from the show, now I really started to get wet. I held off on touching myself because I knew I wouldn't be able to be quite about it. I stayed at the door till it sounded like he might have finished and I slipped back to my room.

I closed the door, ripped off my cloths and hopped onto my bed. I started rubbing up and down my lips avoiding my clit. I started thinking about what just happened. I slipped two fingers inside myself getting them nice and wet. I held my breast and pulled slightly at my hard nipple. I used the tip of my wet middle finger to lightly brush my clit, a moan escaped my lips. I released my breast and put two fingers of that hand into myself and started sliding them in and out. My finger tips on my other hand continued to tease my clit picking up speed. I also continued to moan softly.

Ryan had just made a deliberate trip to watch me change, and then went back to his room to masturbate. My orgasm hit me like a truck. I cried out followed by more moans and yes's as I rode out my orgasm. I decided that tomorrow it was time see if Ryan was ready to go farther. I didn't bother getting dressed or covering up, enjoying the air on my tingling skin. I drifted off to sleep excited about tomorrow.

The next day I wore my bikini under my jean shorts and shirt. I continued wearing my old one piece swimsuit as I continued swimming regularly in the backyard. Ryan normally sat outside on the patio furniture or on the couch watching TV. My mom told me that even when he was in front of the TV he was doing a lot more watching me than the TV. After lunch I decided to go for a swim. I waited till Ryan was in the kitchen before going outside and getting into the pool.

I swam for a while like normal doing a few laps and just enjoying the cool water on a hot day. I wasn't sure if my nipples were hard from the water temperature or what I hoped was about to happen. When I was pretty sure Ryan was looking past the TV at me I got out of the pool. I could feel the water running off my hair down my back and off my breasts. I glanced inside as I faced the house and reached for the towel I had left outside earlier.

Ryan’s jaw was just about on the floor and I wasn't sure his shorts weren't going to start blowing stitches. I used the towel to remove some of the water from my hair, hopefully stretching in ways that were interesting for Ryan. I then patted myself mostly dry turning around a few times during the process to be sure Ryan got to see everything. I hung the towel over my right arm so it wouldn't block his view of me as I walked past him. He had recovered enough to shut his mouth and it looked like he had adjusted his shorts, but they still seemed to barely contain him. I smiled at him as I walked past him heading for the stairs.

Once in my room I left the door a little further open than normal. I finished drying off and stood with the towel in my hand and back to the door. I only had to wait a few more seconds before hearing the familiar sound of Ryan coming up the stairs. When he stopped outside my door I tossed the towel off to the side on my floor and reached up behind me untying my bikini top. I lifted it over my head turning slightly so my left side could be seen from the door. Then I turned at the waist fully exposing my left breast to the door and looked Ryan right in the eye. He froze.

I was glad he froze rather than trying to duck around the corner. While I continued looking him in the eye I reached down and slowly pulled the string untying the left the side of my bikini bottoms. Seeing the movement his eyes left mine and looked down at what I was doing. I untied the right side more quickly and pulled them off tossing them over near the towel. His gaze quickly looked up at my eyes again then back down at my trimmed pussy. His right hand slowly moved toward his crotch as his eyes slowly moved back up my body to lock with mine again. I smiled seeing his hand moving. Seeing my smile he moved his hand more quickly the rest of the way to his zipper.

I looked at my bed and walked over to it. I crawled on to it on all fours and looked back at him as his cock sprang from the front of his shorts. I sat down in the middle of my bed and moved my right hand to slide a finger into myself.

All the glimpses I had given him of me were always “innocent”. I did not let him see me masturbate or anything else overtly sexual. His right hand wrapped around his cock and started furiously sliding up and down the length. The tip was glistening heavily. "Oh yes," I said watching him moving my finger to rub circles over my clit. He continued pumping while his eyes roamed up and down my body meeting my eyes each time they came to the top. I watched his hand in a blur looking up and deep into his eyes while small moans again escaped my lips. I reached up with my other hand and pinched my nipple. This was too much for him and grunted deeply as the first jet of cum flew to land on the floor of my room. "Oh God Yes!," I cried seeing several jets of his cum fly into the air. My body started shaking and I had my strongest orgasm yet. My eyes were forced closed as I rode wave after wave before I was able to open them and look over at Ryan. The last bit of cum dripped from the tip of his cock to land at his feet.

"That was so fucking hot," he said.

"That was amazing," I replied.

I lay on my bed still tingling and trembling slightly. Eventually he looked away from me to his cum on my floor. "Sorry about the mess."

I got up, steadied myself for a second and said, "No problem" as I walked to my drawers. I opened one and pulled out a pair of white cotton panties. "I'll take care of it." I walked over to his cum furthest from the door and wiped it up with the panties. I continued till I got to the spot at his feet. I dropped to my knees and wiped up the last bit. I stayed on my knees, sat back, and looked up at him. His cock twitched as I said "I better put some clothes on before dinner." I smiled up at him as he put is cock back in his shorts. He stepped back and I stood up and closed the door.

I decided to wear a short skit and shirt that exposed my stomach to try and remind Ryan of all the skin he saw earlier. The evening passed as it normally does with all of us having dinner, and then sitting down in front of the TV. My parents sat on the couch together while Ryan and I sat opposite of each other in chairs. Small smiles passed between Ryan and I throughout the evening and my mom took notice. My dad got up and headed to the kitchen to make a bowl of popcorn. As he walked past me I caught Ryan’s eye and spread my legs a bit. He looked down saw I was wearing the white cotton panties I used to clean up his cum from my floor. He immediately stood up and headed for the stairs calling over his shoulder that he was going to turn in early. I smiled at his back as he walked away and mom slid over to me. What was all that about.

I told her about him watching me change last night and masturbating when he got back to his room. Then details of how I got him to my room and the mutual masturbation that followed. Then I told her about the cum covered panties I was wearing. During the story her nipples became very clear through her shirt. When I got to the part about the panties she looked down at my skirt and back up to me smiling. I told her I wanted see if I could catch any of the show upstairs before turning in. I stood and headed for the stairs.

When I got upstairs I headed to Ryan’s room hoping for a glimpse of him jerking off again. Unfortunately his door was closed and when I put my ear to the door I didn't hear anything. I was disappointed; but between the anticipation of what was going to happen, what happened, and putting on the panties I had already had five orgasms today. I guess that was enough for one day...well maybe one more before I drift off to sleep. With that I headed to my room.
