[m]y very curious step-sister and her [f]riend

Let me preface this story with a little background. This happened 3 years ago. I was 20 and my step-sister and her friend was 18. My mom married her dad when we were 14 and 12, respectively. She always has friends over the house and I've known all of her friends for a few years.

It was a Friday or Saturday night because she was allowed to have a friend sleep over the house. I knew this girl, but not as well as the rest of her friends. Her name is Amanda. Amanda and Sam (my step-sister) were up really late that night doing well… whatever girls do at sleepovers. Our rooms are connected by a bathroom with sliding doors on both ends. Picture my room being on the far left, then a bathroom in the middle, then her room on the far right. Our parents slept all the way on the other side of the house. I was really tired that night. I think I was up late the night before playing a new video game, so I decided I should fall asleep at a decent time. It was around 12:30 AM I was awoken to the sound of obnoxious girly laughter. The kind that pierces your ears because it's on a whole other frequency level. I was about to leave the comfort of my bed to go yell at them to keep it down, but just as I was about to get up I heard what they were talking about…

My step-sister's friend Amanda was asking questions like, "Have you ever seen his dick?" and, "I would make him cum before you!" Since I was awakened half-way through their conversation I had no idea who they were talking about. In my mind I kept running through the list of guy's names they had a crush on. Just as I was processing who it could possibly be I heard my step-sister say, "Maybe we can try to peek at Bellshamy in bed!" Just then my heart dropped. They've been talking about me the whole time. I felt like a kid in a candy store. The adrenaline was pumping through my body so much that I rolled over too fast and my squeaky bed let out a loud noise. Just then I heard my step-sister again. This time she loudly whispered, "Shhh! He can't hear this or I'll die!" That alone made me even more excited.

I've always been attracted to my step-sister and her friends, but I never in a million years thought of anything truly happening. Let me describe both Amanda and Sam. Sam (step-sister) is about 5"2, long black hair, hazel eyes, very skinny I'd say around 110 lbs, pretty good B maybe C sized boobs, and her butt is her best feature. It's not massive but it's so perky and sticks out a fair amount. Her friend Amanda is kind of her opposite. She's about 5"7, long blonde hair, really blue eyes, always tan, average weight and close to size D boobs. Her butt is nice, but nothing like Sam's. I'd have to say that both girls are easily 8/10 or higher in just looks alone.

I listened more intensely as their conversation progressed. I could tell Amanda was egging on my step-sister. It was clear both of them were into it, but I could just tell by the tone that Amanda was pushing for them to do something. I almost wanted to burst through their door, but the rational part of my brain took over and said, "Don't do that you idiot!" Just as I was thinking of more scenarios I heard the bathroom sliding door on my sister's side fling open and saw the light peeking under the door. I heard a lot of rumbling going on. Toilet flushing, sink at full blast, and then I saw my side of the bathroom door slowly slide open. I quickly pretended that I was dead asleep. Just as my side of the door shut I shot up waiting to hear their next conversation. I couldn't hear the next part very well, but Amanda said something alone the lines of, "I just checked and he's completely asleep!" Now my heart was racing. I frantically undressed myself and slipped back under the covers. Since I couldn't hear that well I thought it was my brain playing tricks on me. I quickly calmed myself down and a few minutes later I heard complete silence.

Just as I thought they might have gone to sleep and all hope was lost my sliding bathroom door creaked open even slower then last time. This time it was wide enough for a person to slip through. They didn't even turn the bathroom light on, probably in hopes not to wake me. I could see both of their shadows creeping toward my bed as I laid their still as could be, pretending to be asleep. If you could imagine closing your eyes and just barely squinting where you look like your eyes are closed but you could still see blurry objects, that was what I was doing. I could see their blurry hands wave across my face as a last check to see if I was truly asleep or not. I heard Amanda whisper as quietly as she could, "Do you think he wears any clothes to sleep?"

My step-sister replied back, "I have no idea! Wait, what if he wakes up!? I don't know about this!" I was lying on my back, holding every muscle back in my body from even twitching. Amanda said, "Okay let's see if he starts waking up when I move the covers!" Amanda then started slowly peeling the top cover away from my body and stopped right before my waist. My entire upper half was exposed for both of them to see I had no shirt on. I could just tell they were curious to see if I was wearing anything on my lower half. Amanda whispered to Sam, "Now it's your turn!" Reluctantly Sam agreed and she started to undo the second part of the covers. She hesitated a little because as soon as she started she could see I wasn't wearing anything at all. I heard both of them simultaneously say, "Oh my God!" I could tell this is what they wanted to see all along. With the most determination I could muster up I kept myself from getting hard and laid perfectly still as the rest of the covers had been lifted from my body. When it was done I was completely naked with both of them hovering just a foot away from me.

I heard them talking about my flaccid penis saying stuff like, "I wonder how big it gets when he's hard!?" and, "I dare you to touch it!" Then Amanda commented, "Sam look at his balls! He totally shaves them!" They both started doing a nervous snickering laugh. The feeling of knowing all of this is happening while preventing myself from getting hard all while wanting to make something happen was mind blowing! A second later I felt a cold hand touch the tip of my penis. It was Amanda. Sam said, "Oh my God! What are you doing!? He might wake up!!" Amanda just replied back, "Shh! Try it, it's so much fun!" All this while she kept doing a rubbing and poking motion on just the tip of my penis. I started to get semi-aroused at this point. I just couldn't help it. Right as that was happening I saw a blurry vision of Amanda taking Sam's hand and placing it right on my shaft.

Sam just stood there frozen with her hand grasping my entire penis. I immediately went from semi-erect to full on hardest boner of my life. I could hear Sam freaking out to Amanda saying, "His dick just got really hard! He's gonna wake up!!" Amanda calmed her down again and Sam just decided to go for it. Without Amanda even saying anything Sam slowly started rubbing up and down on my shaft with one hand while her other was playing with the tip of my penis. She started to get more aggressive as time passed and gently scooped my balls in her non-dominant hand while still jerking me off. She was rubbing her hands all over my lower half. Every now and then Amanda would jump in and start rubbing me. I could half see them looking at me wondering if I would awake. By this point I could tell they didn't care too much if I woke up. They were too far committed. Just as I was about to "wake up" I felt Amanda suck just a tiny bit on the tip of my penis while Sam caressed my balls. Just as Amanda took her lips off the tip and Sam placed her hand back on my shaft I exploded. I "woke up" just as I had cum, but didn't say a word. I could see that I shot a load right into my step-sister's hand and all over her lower forearm. A little bit even managed to hit the bottom of her chin as she was hovering over me. Sam started to freak out saying to me, "I didn't know what I was thinking! Please, please, please don't tell anyone this! I'm so sorry!" She didn't even care that I had just came all over her. I interrupted her half-way through her apology to let her know that I enjoyed it a lot! She asked if I was awake or not during the whole thing. I feigned ignorance and said I was asleep, but awoke just as she made me cum. She was so relieved to hear that I loved it.

Amanda, without even hesitating, took a little cum off of my dick and tasted it. I asked if it tasted good, and she said it wasn't bad and that she had never done that before. I asked Sam if she's ever tasted cum, and still kind of shy she replied, "Umm no I haven't." I asked if she wanted to and before she even said another word she started to lick her hand where the majority of my cum ended up. She loved the feeling so much that she licked up all of it. All of us talked for a little while after on my bed. I was still completely naked and asked the two of them if they would join me. They both stripped naked and we cuddled up in bed and talked about so many things. I let them know we should do this again, but I didn't want it to become a regular thing. They both agreed it was a good idea.

Since that night I've had sex with both of them 3-4 times each. Only one time did I get to have sex with them both at the same time though. The other times I had sex with Amanda my step-sister would watch but never join. We haven't really seen much of each other lately, and I think it'll never happen again. All I can say was that night was fucking incredible, and it led to some amazing sex!

Tl;Dr: Step-sister and friend tried to be sneaky and see me naked and jerk me off. Woke up and came on step-sister. We all loved it. Sexy time happened afterwards.
