I found summer boring after Shell left for college. I ended up staying home more often than not. I watched way too much porn, and I masturbated more often than I'd like to admit. When I did hang out with my friends, it wasn't as fun without Shell. It got old quick especially without any women around. There was Steve's girlfriend, Kim. She is rather cute, but she's hung out with us for so long, I might as well count her as a guy.
Jamie, my older sister, recently came home from a 30 day summer session at college. I never really thought of my sister as anything more than an annoying decent looking girl that I could catch a few flashes of skin now and again because she was right there. Growing up in a strict home, I knew incest was terribly wrong, but I never had any real desire for Jamie. My only desires were to catch a look at a naked girl up close.
But in 4 weeks since graduating high school everything has changed. The sudden jump start to my sex life combined with its equally quick complete stoppage has caused my hormones to go crazy. I have found myself looking at my sister in a different manner. Instead of trying to catch a view of her skin, now I cannot get her off my mind. She is medium height maybe 5'6" or so with dirty blonde shoulder length hair. She has the hourglass figure of a college freshman who had a little more beer than exercise in her first year of college, but she still was in decent shape. Her tits were easily a 36C if not D cups. The biggest difference in my sister since high school is the large amount of cleavage she shows off now. It's not often that she isn't wearing a low cut tank top.
Our parents were out of town for the weekend, and I decided to try something, anything with her. I wasn't sure how far I wanted it to go, but I wanted to try. I knew it was wrong to want your sister, but I needed to find something new to get off on. Thoughts of my sister's tits helped me make up my mind. It was early Friday evening when I heard our shower turn on. I walked over to the bathroom door to quietly test it. It was locked. Being a Jack and Jill style bathroom shared by two siblings of the opposite sex, both of the door locks face my room. Leaving both latches facing my sister. If the bathroom is open to my side, I can get in the bathroom, but she can lock her room. And if she's in the bathroom, she can lock the bathroom door to my room from inside the bathroom. The only downfall earlier in life was that my sister could then come into my room anytime she wanted through the bathroom, but I couldn't use the bathroom if she had the locks turned.
I waited a few minutes after the water started just to make sure she was in the shower, and I fiddled the lock on the door open. I didn't really intend to jump in the shower with her or anything. Actually, I had no idea what I intended by going in there. But she was now 4 feet away with her totally naked body glistening in the shower. My cock started to harden under my mesh shorts and boxers. Having only seen two fully naked women in real life before, it was an instant turn-on to see Jamie naked, even if she was my sister. Two or three strokes had my cock fully hard. She was turned away from me facing the shower while running her hands through her hair. With her elbows pointed to the ceiling and her shoulders back slightly, it made her breasts seem more pronounced than I have ever seen them. That stance also pronounced her luscious ass and legs. I licked my lips as I stroked. Then Jamie turned around and met my eyes.
"What the fuck are you doing in here!?!" she yelled as she tried to cover herself. One arm wrapped around her chest to cover her nipples but barely covering her large breasts. The other arm reached down covering her pubic region with her hand. "Get the fuck out you pervert!" she continued to scream at me.
I think all that I could get out of my mouth was something about needing something or other from the bathroom. I rushed back into my room closing the bathroom door, as something else hit the back of the bathroom door. Back in my room I felt totally fucked. Should I be trying to do something here, or is it just totally wrong to want your sister? I felt conflicted, but entirely full of desire. This was different than my desire for Shell. I loved Shell and thoroughly enjoyed fucking her. Wanting Jamie was far more enticing right now. Mostly because it was taboo.
I knew that she was going drinking with her friends tonight. Often she comes back from the bars horny, and I can sometimes hear her masturbating in her room. The thought of my sister masturbating disgusted a younger me. But today it got my mind going, how could I make sure that happened? Was there anything I could do to ensure I could watch Jamie touching herself? I felt dumb, but the thought of her naked body turned me on so much I wanted to try something else.
The idea I came up with was stupid, and never should have worked. It was like a five year old trying to con their parents into their way. But I had two nights to fuck Jamie before our parents came home. I knew the bars closed at 2:00 A.M. so she would be home sometime in the next hour or so after depending if they stopped for food or not. I put the hottest porno I own on in the DVD player in the living room, then went back upstairs.
Waiting. I felt like going downstairs a 100 times. Put an end to this stupid plan, but I never did. I didn't know what she would do when she came home. I hoped that she would think that I jerked off watching the porno on the big screen, finished my business and just forgot to turn it off before going up to bed.
3 A.M. Laying in bed playing a video game, I hear Jamie stumble in the front door, drunk. Probably more than just drunk, wasted as usual. Hopefully, I hear something. Did she bring home some guy tonight, or what? I try to listen, but I can't hear anything. I try to give it a few more minutes to see what happens.
3:05 A.M. Still nothing. Nothing at all. I should wait longer to check just so I don't run into her on the stairs or anything.
3:10 A.M. I walk down the hall and look over the balcony. The sight is just what I hoped for. My sister is half-laying on the couch rubbing her crotch over her jeans. Holy fuck, this is awesome. But being me, I want more than just watching this from up here. I quietly but very quickly walk back down the hall and down the back stairs through the kitchen towards the living room.
I tried to be quiet walking into the family room, but there was no need. The scene on the television showed two big tittied lesbians moaning while one was fucking the other doggystyle with a strap-on. In any other situation, the scene on the television would have kept my full attention, but the action in the room had me exited. Jamie was laying on the couch with her jeans and panties down around her knees. Her tank top was pushed up over her breasts to the top of her armpits. Her ample breasts were spilled out over her push-up bra that kept her tits pushed together. They looked massive. Her eyes were glued to the screen and both hands were wrapped around a large pink vibrator pushing it in and out of her pussy. She must have had that in her purse or stashed somewhere in the room. I could hear the muffled sound of the vibrator's pulsing each time she pulled it out. I got this far, but had no plan what-so-ever of what to do next. So I did the first thing that came to mind. I stripped off my clothes and proceeded to walk into the family room hard cock in hand. Finally, I sat down on the couch between her and the entrance to the kitchen.
"Can I watch with you?" I asked.
She sat up actually leaving the vibrator in her pussy saying, "You fucking pervert, I'm gonna tell mom and dad."
"You're gonna tell them what? That I interrupted your dildo session while you were watching porn on the big screen in the family room? I'd like to see that," I joked back.
But instead of leaving, she moved further down the couch. "Stay if you want," she said. "But you need to stay over there." I was shot down, but I did catch the way she eyed my cock.
With her full attention back on the movie, she sat up fully and kicked her jeans and panties off to the ground. She pulled the tank top the rest of the way over her head too. Leaving only her bra on with her tits on full display spilling over the top of it. Her right hand went back to the vibrator starting to slide it in an out of her pussy again. Her left hand found her way to her giant nipples. She pulled and tugged on the ends of her nipple making her areolas darker and more pronounced. My hands having been on my cock this whole time continued to stroke at as slow of a pace as I could make myself. My head was on a swivel, alternating between watching my sister play with herself, and every time her pleasure seemed to intensify I would glance to the screen to see the hot action on the TV. The one of the lesbians was riding the other cowgirl style using an L shaped dildo instead of a strap-on now, so they could both fuck each other. That was so hot I wanted to keep watching, but I couldn't lose my focus. Jamie started to sigh with long breaths as she fucked herself. I tried to match her breathing with my own. My strokes now keeping up with her dildo. Then she started to glance at me in between watching the lesbians on screen. All my senses were starting to get overwhelmed and knowing she was trying to watch me or even trying not to watch me. I didn't know, but she was glancing over at me. I couldn't hold back any longer. I started to cum, blowing my load all over my stomach. Moments later Jamie's whole body started to convulse and shake. She then became very still as she let out several long moans with her head tilted back as far as it would go. I saw her right hand pushing the vibrator in and held it in at its full length. I leaned over to her body, and lapped my tongue over her exposed hard nipple before engulfing it into my watering mouth. She allowed my sucking until the moaning during her orgasm subsided. Then used her other hand to push my head away. She was obviously still feeling the sensations of her orgasm as she stood up and walked away with her vibrator in hand calling me a pervert. She left the porno playing on the television and her clothes strewn across the floor. I watched for a little while longer until exhaustion started to overcome my body. I decided to head up to bed ignoring thoughts about trying anything more with Jamie tonight.
The next morning I was awoken all too early by a phone call from Shell's mom asking me to come over to help her move a couple large things around the house. I agreed to come over shortly, but got an extra hour of sleep before heading over. Apparently there was no furniture needing to be moved, which made for an extremely enjoyable morning. I had left Shell's house an hour or so before her dad was supposed to get home from work.
Not long after getting home I found myself laying in bed naked watching porn on my laptop. I've found that the more often I have sex, the more often I am turned on when I'm not having sex. This has led to a vast increase in my masturbation schedule as opposed to before that Sunday afternoon with Shell and her mom. I found myself thinking of those large breasts that were recently cupped in my hands. Shell's mom's skilled hips riding me. Her ability to let me slowly enter her followed by a compelte release of my cock. This allowing every nerve along the ridge of my cock to feel the sensation of be engulfed by her pussy. Followed by a full change of pace to furious humping urging my body torwards release. And of course slowed back again, to a creep prolonging the teasing until my impending climax was built up to the point of nothing being able to hold it back.
Wishing for the feeling of Shell's mom back on top of my cock, my bathroom door opens. Jamie walks in asking, "Watcha doing? Having some fun are you?" For whatever reason I quickly tried to cover myself up with a pillow, but offered no verbal resistance to her being there. "You didn't get enough this afternoon with Mrs. Anderson? Yeah, I know what you were doing today, or should I say who you were doing."
Jamie looked pretty good right then, with her dirty blonde hair pulled up in a folded over pony tail thing so the ends of her hair were come back up. She was wearing a bikini top and jean shorts with the button undone and the zipper part way down. I could see her bikini bottoms above the zipper. I love this look on anyone. On a blonde like Jamie with big tits, I liked it even more.
