I grew up in a mid-size city, a middle class family and mostly sheltered from the big city life of Chicago just a few hours away. We didn't have rave parties and orgies, but we knew about them of course. I was the oldest by three years and always very protective of my baby sister. My family and I tried to keep the realities of inner city life away from her the best we could.
The world really opened up for me when I went away to college at Northwestern University. I found the "big city" temptations of drugs, orgies, and parties all in the microcosm of the campus. When my sister Diane turned 18 and graduated High School she joined me at Northwestern. I insisted we share a two-bedroom apartment and naturally my parents agreed. It made sense to save money this way and besides I would be able to watch over my virginal baby sister and keep the wolves at bay.
Boy was I ever mistaken.
The arrangement would cramp my style a bit. I was currently dating the wildest woman I ever met, Lila. She was an art major who rocked my world. She was a little shorter than I at 5'9 and volunteered to be a nude model at the art department. She worked at the local Hooters wearing those orange short shorts and skimpy white tank tops that really accentuated her 38C chest. We had dated for a couple of weeks when we started having sex regularly she was nearly insatiable. She would want us to role-play. I would pretend to be an art student and she would model and I would change her poses resulting in sex. Or she would pretend to be my French professor and seduce me.
We acted out our fantasies and it opened a new world for me. Then one night after sex we cuddled together and she told is she was bi-sexual. She also stated she would love to have a threesome with me and another girl. I was intrigued. Okay... I am a guy... so I was very excited. Since then wherever we went and saw a beautiful girl I'd whisper to her "how about her?" She would play along in a teasing way, but it never really materialized and after a week or so I just dropped it as one of her fantasies.
When Diane moved in, Lila and I had to curb some of our role-playing activities to the confines of our bedroom. I also felt embarrassed about having sex while my sister was awake in the living room or the bedroom next door, so we either waited till she was asleep or was gone. Most of the time on the weekends, I spent the night at Lila's place.
Diane and I got a long. She made fun of how protective I was of her. I would say stupid things like "Lila and I are just sleeping over because it's late and I don't want her to drive back to her place so late". My sister would recognize these apparent attempts to mentioning sex to her and she played along or teased me with "oh just sleeping eh... sure"
Now Diane is beautiful. At 5'5 she was prom queen, head cheerleader in high school and all that stuff. She is majoring in Drama and probably is destined to be one of those beautiful movie actresses. Most people think she looks a lot like Jessica Alba, but with a larger chest. Perhaps that is why I was always so protective, making sure the guys she went out with were "good guys" not slime or perverts. We both new and even Lila told me she assumed that my sister was having sex when she went out on dates, however, I didn't want to hear it or know about. My ignorance in her sex life was my bliss.
Let me defend myself here. I was protective but I wasn't fatherly. Diane had her own social life. She would drive out to parties or her girlfriends and go out on dates. The fact being that the more she was away from the apartment, the more fun Lila and I could have.
All that was the setup... now comes my story and perhaps you can help me with my problem.
Diane went out to a party and it was going to be one of those all nighters. I finished up at the library and raced home because Lila was going to be waiting for me to do some special role-playing she had planned. It was about 10:30 PM and I saw that Diane's car was gone from her assigned parking spot. I saw Lila in the guest parking and raced up to the apartment.
When I opened the door I saw the lights were off except for a couple of candles. There were two empty bottles of wine on the coffee table and some soft music coming from my bedroom. I grinned, wondering what Lila had in store for us tonight. I silently opened my bedroom door and saw in the dim candle light Lila nude on my bed facing down, her ass facing the door. I smiled and started taking off my clothes but then I her moaning and as my eyes adjusted it dawned on me that there were two people in the bed. In fact there was another girl under Lila and they were in a 69 position.
"She did it" I thought. She went and got us another girl. This was what she was planning and she picked the perfect night when my sister was gone.
I quickly undressed and moved to end of the bed. I couldn't really see much of the new girl since she was much smaller frame and her face was buried in Lila's pussy. The girls head was at the foot of the bed and Lila's legs hung over. Not to startle them I gently placed my hands and rubbed Lila's ass and hips. She moaned with approval as I began to lick and nipple at her ass, all the while trying to get a glimpse of the girl underneath without luck.
My cock was so hard watching this action I rubbed it along the crack of her ass while holding her hips. She stopped snacking on the snatch long enough to whisper a horny "yes" as she buckled her ass upward a little to allow me access. My cock found it's way easily into her very wet pussy. The girl underneath her didn't seem to mind, in fact I could feel her tongue running along my cock as it drew in and out of Lila's pussy. As I started pumping her faster the girl underneath licked my balls and when she took them both in her mouth I came in force. My own knees buckled and I climbed onto the bed leaning up against the pillows and backboard in a halfway sitting position.
Lila move up off the girl and laid on me kissing my lips. I tasted the sweet vaginal nectar of her female lover. While Lila and I kissed the other girl had shifted to the side and was licking my wet cock. I looked over to get a look and saw that the girl was indeed Diane... my sister.
It took awhile to register. I was just too confused. A hundred questions ran through my mind. I placed my hands to my side to jump off the bed but Lila moved laying across my chest.
"Now baby... I let me explain. Your sister called the house saying that the party was turning ugly, she was drunk and couldn't drive home. So I went and picked her up. When we got back we were talking had some wine. We started talking about girl stuff and sex and stuff... things... just... happened. Soon we were kissing and stuff... wound up in here. Hey I told you I was bi... I guess your sister is too."
"Shit, she's drunk. She doesn't know..."
"Oh please... being drunk doesn't turn you bi, don't be naive."
"Oh jeez... my baby sister is sucking my cock... it's perverse... get her to stop"
Lila just chuckled "what it feels bad? Maybe she needs help"
Lila then moved down and both of them were licking my cock and sucking my balls. I know I should have pushed them both away. I should have thrown Lila out of the apartment and locked my sister in her room. All these things were flashing in my mind like a movie. But still I lay there, enjoying the sensation. The only thing I could think of doing was to close my eyes to it all.
My cock was hard again.
The bed shifted.
The cool air hit my cock and then it was engulfed in warmth. A tight fitting warmth.
I opened my eyes and my sister was sitting on my cock her head arched back letting her long black hair hang down her back. She was fucking me, pouncing on my cock. Instinctively I moved my hands to her hips and moved her up and down. I stared at her large firm tits and touched her nipples. As I did so I turned to look at Lila who was leaning on her elbows looking at me with a huge smile on her face. I felt embarrassed that I was enjoying touching my sister and withdrew my hands from her. This caused Lila to snicker at this gesture because one hand still held her hips firmly as my own ass moved to meet each thrust of my cock. We both orgasmed. The shooting of cum into my tight little sisters cunt brought involuntary shudders to my body. My sister collapsed on me. I rolled away, lifted her up in my arms a carried her to her own bed. I covered her with her blanket taking in one more look at her gorgeous 18 year old body. I went back into bed and Lila and I cuddled together and fell asleep.
The next morning I woke up late. Lila was gone and my sister had taken off to class. I skipped class that day. I could only concentrate on how ruined my life was. How would things change? Should I even see Lila again and how could I face my sister again? Was my family ruined?
I successfully avoided Lila for the whole day. When my sister got home she had acted like nothing happened. She talked about her classes and something on the news.
She moved about the apartment putting away her books and making a sandwich. For the first time I was watching her not like my sister but as a hot chick. I stared at the way her ass moved as she walked. I stared at her breast as they hung from the confines of her shirt.
"So what happened last night at the party" I asked.
"Oh everything was fine, a got a little drunk then some jerks from some frat showed up and they pissed off my friends. I called Lila to take me home cause I drank too much to drive. Aren't you proud of me? You always tell me not to drink and drive."
"Uh huh. So Lila picked you up?" I was fishing...
"Yeah" she said in between bites of her sandwich. "We got back had some wine. I most have been really trashed, I don't even remember going into bed. Ha ha"
I wondered. Could I be that lucky that she was so drunk she doesn't recall fucking Lila and I. That my whole world won't crumble? Now all I have to do is tell Lila and make her swear that she will never tell Diane or even mention that night again.
"Well, such are the perils of alcohol sis. Be warned." I laughed it off couldn't believe my luck.
"Yeah well the hangover I had in the morning was warning enough. I am going to take a shower".
I tried getting Lila on her cell phone and we made a date to meet at a Pizza joint we liked. Diane then came out of the shower with a towel wrapped around her hair and totally naked.
"Hey what the fuck?"
"Oh please big brother. It's not like you haven't seen me naked." She then winked and walked into her room wiggling her ass.
I ask you... what did she mean by that? Do you think?
