I decided that I had to be content to just watch them fuck and then sneak back to my room to finish myself off, that is, if I didn’t finish the job right here.  My need to cum was not gonna wait too long.  It was most likely gonna happen right here as I watched them.  I moved two fingers slowly over my clit, so as not to make any noise moving in and out of my soaked cunt.  I could cum either way, rubbing my clit or using my finger inside, but I surmissed that this was safer, quieter, and faster.   I also had to make sure that I didn’t cum too soon.  I was hooked and I wanted to watch the whole show.   I didn’t want to finish before they did, before Ted did. My need to imagine him finishing inside of me was now of the utmost importance.

My brother in law decided to change positions at that moment and to climb on the bed and on top of my sister. I lost my viewpoint.! I wanted to shout out loud “Noooo!!!”, but I didn’t   They had moved up the bed in order to make room for him, and they were now out of my eyesight.  I needed to push the door open wider or else I needed to leave.  I heard Ted begin slamming into her again followed by more intense moaning.   I had to decide, so I did.   I slowly pushed the door open some more.   I was not about to give up this experience.   I was addicted to the rush. 

It hit me how open the door actually was now.  If either of them looked this way, they would easily notice how wide open the door was and possibly get up to close it.  I needed to be more careful, but my lust was controlling me now.  I wasn’t here just to listen to the noises they made while fucking, I wanted to see it, to experience it, to live it.

My sister’s grunt was an indication to me that Ted was pushing in deep.  With something that big and long, I would grunt too if he shoved it into me.   Oh, how my mind was wishing he would.   Her grunt quickly turned into low level cries of “Fuck me baby” and “I love your hard cock.”   He began pumping harder into her as she continued her verbal onslaught of sexual persuasion.  “Harder, Baby, Harder!”  The sounds and words coming out of her were unlike anything I had ever heard her use and they were pushing me towards my limit.   I was watching with one eye around the door when I moved my head further in to see clearly all the motions taking place on their bed.  I wanted to be her right now, being filled with my brother in law’s cock and being pushed towards the edge.  

My hand was busy moving slowly over my clit, but with hearing my sister’s begs for more, my fingers moved down across the slick lips below.  They felt bigger, puffier, with my excitement.  My emptiness needed to be filled, to have something shoved deep inside.  With one finger alone, I slid it inside as I moved slightly further into the doorway.  My entire face would be visible to them if they had turned to look at the doorway, but I didn’t care.  I needed to see him giving it to her!  Anyway, they were too busy to notice me.  I needed a clearer image to burn into my memory for my future masturbatory sessions. This would be my new fantasy for years to come and I wanted as much of my memory filled as efficient.  Olivia and Ted were now becoming forever burned into my sexual future.

My finger came out slick with my juices and it went right back in.  I was pumping myself at the same speed as Ted’s movements inside my sister.  I matched him pump for pump, as if he were fucking me instead of her.  His amazing sexy ass was rising up and falling hard as he forcefully drove into her.   I wanted to finish with him, at the same time, if efficient.  My mind made my finger a small fantasy version of him.   I added a second finger because one wasn’t enough, he was so much thicker than just one finger alone. Then, a third was added in order to equal what I was seeing enter my sister.  His thickness was stretching her, stretching me.  His breathing was still steady but becoming more rapid while I was getting closer to my finish line.  With three fingers pumping inside me, I needed to slow down before I finished without him.  I was getting weak in the knees and needed to lean against the doorframe in order to stay standing.  That’s when the wood creaked.  I instantly stopped!  I closed my eyes tight in disappointment and slight anger.  I knew it was loud enough for them to hear, but were they even listening? Could they hear that over their own sexy noises?  I hoped not.

I waited a few seconds and listened for the steady rhythm of Ted’s cock still penetrating my sister’s wet pussy before I dared to open my eyes.  I hoped, because they didn’t stop at the sound of the creak, that it meant I was unobserved and safe to continue my voyeurism.  Instead, what I opened my eyes to was my sister staring right at me even though her husband was still slamming hard in and out of her.   I froze, motionless, staring into my sister’s eyes.  Our eyes met and I knew I was caught.   Ted’s head turned towards me next and my embarrassment multiplied exponentially.  Even in that little bit of light from the room, I’m quite sure they could both see my red-faced embarrassment.  Here I was, being caught watching my sister and her husband have sex, by the participants themselves.  The worst part of it all was that I still had my hand down my panties and my fingers lodged deep inside my pussy, which I’m sure they could both clearly see as well.  

Yet, surprisingly, neither of them looked angry.  Ted seemed surprised while Olivia looked… happy?  Was that a slight smile on her face I saw?  I started retreating backwards out of the doorway and into the hallway, ready to return to my room, or just get in my car and drive away when the unimaginable happened.  Beyond my wildest fantasies, my sister beckoned me into their room with the wag of her finger.  Did I imagine that?  Not even in all the years of my devising sexual scenarios did my sister ever make the first move to invite me in.  Yet here she was wagging her finger a second time.  She was calling me into their room, for what reason I didn’t know or figure out.  Ted had not stopped fucking her even though I was being summoned in.   

I hesitantly entered the room, waiting for her to change her mind or to begin yelling and screaming at me for invading their privacy.  When she saw me enter their room, she broke our gaze and returned to enjoying her husband’s invasion of her body.  “Looks like we woke someone up.” she said gazing up at him.  Ted added back to her, “Looks like we have an audience.”  He turned his head to look at me again, lust and desire burning in his eyes.   His smile melted me, made my insides tingle.   He turned his attention back to Olivia and back to the performance he was giving.

I made my way along the side of the bed and stood against the wall at the bottom of the bed.  My shyness and embarrassment kept me out of their range of sight for now and into a perfect position to see their sexual connection.  I was behind them watching Ted’s ass, his balls, their place of union.  Suddenly, I realized that I was in their room in just my bra and panties.   I still had my hand buried in my pink panties.  It had never come out of my underwear the entire short walk into their room.  I concluded that I was there to enjoy the show, so I might as well continue to touch myself, since I was given permission for entrance anyway.  Strangely, it seemed that my sister was ok with me being there, observing her naked husband, appreciating his techniques, and viewing their lovemaking.   By the sounds of it, neither of them seemed put off by my presence.

Just watching him pound into her was making me want to jump in and join them.  I knelt down to get a better view.  I was admiring every inch of him as his cock was disappearing into her wetness and then retreating out to allow me to see his full slick length again.  God, I wanted to be taken by that monster cock right now!  No matter who it was attached to!   I needed a hard cock inside of me!  Yet, all I had were my little fingers which weren’t even half the size of my sister’s human toy.  Still hidden from view inside my soaked and stretched panties, they were moving in and out of my wetness faster and faster matching their every movement.  They knew they were putting on a show for me now, adding a little extra sound and feeling, enhancing the experience.

My orgasm was fast approaching and there was nothing that could stop it if I stayed here watching.  I needed to leave, return to my room, and finish myself off in my own privacy; maybe two or three times after watching this live sex show in front of me.  Could I, should I, allow myself to cum right here, in front of them, watching them?  No, I had seen enough.  I was ready to take my leave when Olivia’s voice broke the air.  My focus was so intent on her husband’s flexing ass, his tightening ball sack, and the slickness of his penetrating cock, that her words barely broke my concentration.  Her head was turned toward me.  She was talking to ‘me’, not to her husband.  I was so intent in my voyeurism that she had to repeat herself to bring me back to reality.

“If you’re going to stay for the show, at least take off your clothes.” she repeated again for the second time.  Was this really happening?  Did she just tell me to take off my clothes and stand here naked, masturbating in front of them, in front of her husband, my brother-in-law?  Yes, I wanted to!!  I wanted to be as naked as they were.  It would make it easier to reach my desperate clit, my aching cunt, yet also more thrilling to have a man, this man, see me naked.  And yes, he was watching.  He had slowed his thrusts and turned his head to see my reaction to his wife’s words.  Without thinking of the consequences, I reached back with my free hand and unclipped my bra with a tentative smile on my face.

The small, wolfish grin on my brother in law’s face, as he watched my bra fall away to reveal my size B tits, told me he was liking what he saw.  My small but firm breasts were out of confinement and on display for him, for them to see.   Their usual, quarter sized, pale areolas were now darker and grown to double their size with my feverish lust and embarrassment.  My nipples were extremely hard in their centers, wishing for some attention themselves.  Even my sister was smiling looking at them.  I have all the time been proud of their shape and firmness but all the time dreamed of having them larger, like my sister’s.  Olivia got all of the attention growing up because of her larger than ordinary breasts.  Yet, there was her husband, looking, like a wolf, wanting to devour mine.   Small, naked, and new to him, these petite globes of pleasure were parading around naked for him to partake in.  And that made me feel desirable, craving more.

The two of them were unmoving, him lodged deep inside of her, while both their eyes were stuck on me.  I was their main focus all of a sudden.  Half-naked, with my hand lodged deep inside my underwear, they were waiting to see what I would do next.  I’m not used to being the center of attention, but my lust had pushed me beyond reasoning and into the realm of instinct.  My one hand left its position inside my secret place and retreated to the edge of my pink underwear.  My other hand joined it on the opposite hip.  It was now or never, and I couldn’t hold back any longer.   My lust was out of control.   I pushed them down to reveal my full bush of hair.  So much hair that it was hiding my swollen pussy lips.  They both had enormous grins on their faces as mine was turning redder.

The pink panties slipped down my legs, over my feet, and onto the floor next to my bra.  There I stood, in all my natural glory, for these two gorgeous people before me to admire.  At that moment, I was quickly moving from embarrassment to pride.  Their eyes leered at me in primal lust and desire.  I wanted Ted to begin moving inside Olivia again, so I could resume my masturbation and finish what I started.  Admiring their two bodies locked together made my body shiver in anticipation of having an overwhelming orgasm    I desperately needed to cum while watching them fuck!  All three of us seemed to be waiting for someone else to move.   Unnaturally, I took the lead and guided my hand back down to my exposed pussy.  I relished in the sensations of my fingers flowing through my long hair down below as both of them observed me.   I moved further down to my already hard clit and waited.   They needed to do something soon because I couldn’t stand there naked with my finger on my clit without moving it for too long.  Without words, my mind begged them to continue.

Olivia turned back and looked at her husband for a second before touching his chest with the palm of her hand.  He moved, but not how I expected.  He slowly retreated out of her pussy.  What was he doing?  My mind was screaming on the inside “Stop!!! Put it back in!”   Was that where I had pushed too far to where I was gonna be thrown out?  When Ted stood up next to the bed, I could clearly see his hard cock, slick with my sister’s juices on it.  It was gorgeous!  I wanted to touch it.  I wanted to suck it.  I wanted to fuck it.  I didn’t want to take my eyes off it.  Then, my sister cleared her throat to get my attention and I looked at her.  She wagged her finger at me again, this time summoning me to her, to the bed, to join them in their marriage bed
