#SexStoriesSaturday EPISODE 10: My Girlfriend's Sister!

                         
It has been awhile since I have had a really great sexual experience.

I do have a steady girlfriend but she is the type of girl who will have sex but does not like it that much. It is not my fault, she just has some emotional problems and is not a very sexual person. Don’t get me wrong, she is an extremely beautiful girl with a gorgeous face and an amazingly fit body. She is also great to be with but sexually, she is very frustrating.

I have been with her for almost two years and have got to know her mother and 18 year old sister very well. In fact her sister, Jane, says she is totally comfortable with me, like a brother. I know this is true because of the way she walks around the house in her swimsuit without caring that I am there. (Most girls are very self conscious of their body at that age.) It is hard for me to be just as comfortable when she does this because her thong bikini is very revealing. This wouldn’t matter much if she didn’t have a gorgeous body. But she does. She is about 5’8″ and 115 pounds. Her legs are so long that I can imagine the way the would wrap around me. Of course she doesn’t help my sexual frustration when she wears the tiniest shorts that just barely show her lower butt cheeks. This girl has got to be perfect.

Over the last year I have spied on her while she watched T.V. on the couch with her legs spread open and her panties showing through the sides of her shorts. I knew that she was a very sexual 18 year old when she casually asked me one day why she had some very erotic dreams about a guy from her school.

Once when I was sick, I fell asleep at my girlfriends house. The door was open in my girlfriends room and Jane had just finished taking a shower. She knew I was in the next room but thought that I was still asleep. She walked past the room topless and I caught a glimpse of her perfectly rounded firm breasts. I had always imagined that they would be great to grab a hold of and cum all over. Although I was sick, I still managed to grab a hold of my bulging cock as I came all over my girlfriends bed.

On another day I sat with my girlfriend on the couch and her sister was laying on the floor. I peeked out of the corner of my eye at Jane’s perfect ass that always gets me hard. It is the type of ass that is not big but not so small that is doesn’t show through her short jean shorts.

I always dream of fucking her from behind. She then got up to go to the bathroom. From where I was sitting, I could barely see the door of the bathroom around the hallway corner. Jane must not have noticed this because she left the bathroom door open as she sat down on the toilet.

She must have thought that I was not going to get up and that I could not see her. I didn’t want her to think that I was watching so I kept my head pointed towards the T.V. but stared with all my might out of the corner of my eye as she finished up. I thought this was great but my dick stiffened immediately when she stood up and faced towards me with her shorts at her knees as she wiped. For that 5 second period I saw what I always dreamed of.

Her bush was dark and neatly trimmed. Her hips were tout and she rotated them ever so slowly in my direction as she pulled her shorts back up. I instantly came in my pants at this gorgeous sight and focused my eyes back on the television as she walked back in the room, not knowing what she had done to me. Jane wanted to sit on the couch so my girlfriend and I laid on the floor. Now I had become comfortable around both of these girls so I did like all guys do when watching T.V. and put my hand down my pants. I knew that Jane could see my hand going down. I then lifted my hand upwards so my pants were pulled away from my waist, exposing my hard dick to anyone above me. Since I was laying down, Jane was above me.

I knew she was watching television but kinda hoped she had looked down to see my big hard dick. I wanted to return the favor. I heard Jane shift on the couch and I imagined that it was because she wanted a better view.

Just then my girlfriend, Susan, said she was going to run to the corner store to get a drink. I told her that I would rather watch this show and so she went by herself. Jane got up and went into her room. I fondled my dick now that I was extremely turned on and was finally by myself.

Just when I was about to cum, Jane’s sweet voice came from her room and was asking me to come and help her with something. I got up and walked toward her room. I noticed that her door was shut. I moved closer to the door and heard a faint buzzing sound. I waited curiously but then knocked on the door. Jane very sensually asked me to come in. I almost died when I saw her almost naked body lying on the bed with a 12 inch vibrator.

She was only wearing some lace pink panties but they were scrunched to the side, exposing her love canal. The vibrator was halfway inserted and buzzing loudly. She moaned as she asked me to come closer. Confused but excited, I walked to the side of her bed. She left the vibrator inside her and used her hands to reach towards my crotch. Quickly, she ripped open the button fly of my jeans, and my rock hard dick sprang out. She cooed with pleasure.

Slowly she began to fondle my cock with her hands as the vibrator buzzed inside her. She then pulled me onto the bed and slowly positioned her mouth in front of my bulging cock. Her lips parted and her tongue moved up and down the sides and top of my dick. She then inserted my entire dick in her mouth and started to move wildly.

The vibrator was still buzzing and she was feeling the pleasure as she moved faster. I could feel her warm wet mouth take my entire dick as I began to cum. She didn’t even flinch when I came into her mouth. She sucked harder and swallowed every ounce with erotic pleasure. Jaime then experienced a great orgasm from the vibrator and the excitement of sucking me off.

She moaned loud and clinched her hands on my ass. Jane removed the vibrator and pulled me towards her. She then got on her hands and knees and begged me to fuck her from behind. I paused a moment, knowing that this was my girlfriends sister. But my dick throbbed at the sight of her ass awaiting my entry.

Before I could think another thought, Jane pulled me into her and I quickly felt her warm pussy. It was wet and tight. I started to move as she moaned loudly. I moved closer to orgasm and so did she. The sex became more wild and then the door to the bedroom opened. When I turned around and saw the eyes of my girlfriend, my heart jumped. What had I done? Then I saw Susan slowly pull of her clothes and I saw her naked body move closer. She said “Jane and I had been planning this for a long time. We always wanted to fuck a man at the same time.”

I was in disbelief. My wildest dreams had come true. Susan moved onto the bed and got on to her hands and knees right next to Jaime. I pulled my hard dick out of Jane and put it into Susan. Susan bucked wildly. Jane then put her wet cunt in the face of Susan and Susan licked like a pro. Jane’s body moved wildly with her big tits bouncing as Susan ate her out. I fucked harder and after a few minutes of pleasure came inside my girlfriends wet pussy. She felt the cum squirt into her pelvis and she came at that very moment.

The excitement died down and I thought it was over. I was wrong. They laid me on my back and began to suck my cock. Usually I can not take this much in one day but I was so turned on that I still wanted more. They took turns sucking my dick and kissing each other. I looked up and noticed that they were also fingering each other. One would suck my balls as the other would move up and down my cock. I felt their hair on my body as they took my dick in their mouth. Then I just could not take anymore so I squeezed the bed and came with a mind blowing orgasm. Susan and Jane shared the cum and it oozed down their faces and tits.

We then got dressed and went back to watching T.V. Their mother came home and asked what we had done all day. “Nothing much” we said in unison and the girls sneaked a sexy smile in my direction. Little did I know that this was just the beginning of my sexual encounter with these two and even more of their teenage friends.
