I, Anna, confess that I have been fucking my best friend behind my husbands back for years.

Part A5: Voyeur [for all the other stories pm me, I can send you the links]
Hey guys :-*** its meeee :D
So by now you surely know that I love to watch other people fuck/masturbate. I would spy on my sisters whenever I could, since I had sex for the first time far later than they did. Now I'll tell you about some other times I watched my sisters bang men.
Some time after my wedding, Haley Patty and I were visiting our parents. We would spend the weekend at our parents place and I was really looking forward to talking to my sisters and my parents again. And not just a little chit chat. No. We could talk about big questions like, getting kids and stuff. We all arrived on friday evening. Mom had already prepped dinner and we were all pretty hungry. It was delicious. Dad and mom seemed so happy together. Haley was looking good, confident. Only Patty seemed absent. Always on her phone. So while Haley and I had a good talk with mom and dad, Patty barely spoke at all. When we changed to the living room and wine, Patty followed us slowly still on her phone. After ten minutes she asked mom and dad if her boyfriend Brian could come over. I saw moms face. She wasnt happy about that. Not happy at all. But she never could say no to Patty.

Half an hour later, Brian arrived. Mom went to bed a few minutes later. Dad followed her. We decided to watch a movie. Patty and Brian had a couch to themselves and Haley and me shared one. Patty got a blanket for herself and Brian. We watched to movie in silence, when I saw a movement in the corner of my eye. I turned my head slightly. Patty was clearly not focussing on the movie anymore... she was stroking Brian under the blanket. He kept looking over to me and Haley as if he wanted to make sure we werent looking. I leaned over to Haley and said "keep watching the movie. dont turn your head after I tell you. I think Patty is giving a handjob to Brian."
Haley turned her head slightly, just as I had and then nodded.
H:"Maybe we should leave them alone.."
Me:"Yes... I guess we should..."
Five minutes later, I excused myself, saying I was tired. Haley followed my example and left soon after. We brushed teeth together and before we went to bed I gave her a big long hug. When she was in her room, I silently went downstairs and to the living room again. They werent even trying to hide it anymore. Patty sat on Brian and fucked him cowgirl style. I was already wet at that point. Patty fucking on our parents couch? that was pretty wild, even for her. I fingered my wet pussy. Seeing my sisters big tits bouncing around, I touched my own boobs. I imagined how I would let Brian believe I was Patty. Make him blindfold himself and then fuck him. A first orgasmic wave rippled through me. I was dripping on the floor! I got a towel to wipe it up. When I was back, Patty was getting fucked from behind by Brian. She wasnt even holding back her moans anymore. My fingers found my pussy wet and ready. I pushed in three at the same time, fucking myself while watching Patty getting hammered. From her moans I could hear that she was getting close to cumming, and so did I. When she finally did, I squirted in the towel. Quickly I went into my room. I licked some juice off the towel. I love tasting my own pussy. Then I fell asleep.

The next day. We all thought Brian would leave after breakfast, but somehow he stayed. Whats more Patty always clinged to him. Every chance they got the made out. Every time we sat at a table, Patty's hand was under the table on Brians lap. It was annoying but also kinda hot. So I made a plan to watch them fuck tonight. When finally everyone was going to bed, I went into my room, got a vibrator and sneaked out again.

The bedroom door of Patty and Brian was closed. I held my ear to the door to hear them speak or fuck. They were actually already on it. I turned the knob slowly and opened the door just a tiny bit. I waited to hear if they saw what happend. No reaction from inside so I opened the door a little further. I could see Patty now. Her back was turned to me and she was riding on Brians dick. She leaned forward and slammed her pussy down on his cock. I could see her juice making his cock wet. I rubbed my clit until I was wet, then pushed the vibrator deep inside my pussy and turned it on. I didnt put it to full power because of the noise it would make then. I kept rubbing my clit. Patty was moaning loudly, not unlike Haley I have to say. I could see her cum all over Brians dick and I came as well. My juice ran down my legs and I had to lean against the wall so I wouldnt fall over on my shaky legs. I turned off the vibrator and pull it out, it was covered in my juice. I licked it clean. I was already going to close the door when I looked inside again. Patty was on all fours and Brian was lubing up his dick. I stopped closing the door. Could it be...? Would he fuck her ass? I inserted my vibrator again and kept watching. Now in their new position, both could see me at any time, they were both facing the door. Therefore I also couldnt see if he was really fucking her ass, but since he was going so much slower and she was moaning in a deeper tone, I just assumed thats what he did. At that time I hadnt had anal sex yet. So I was kinda curious how it feels. I shoved the vibrator deeper into my pussy, turning it on again and then put one, then two fingers into my ass. I moaned quietly. I was afraid they might hear me, but fingering my ass turned me on so much... I came way before Patty did. I kept watching her getting fucked in the ass though, sucking on my vibrator in the meantime. I returned to my room just after Brian shot his cum in her ass.

I never spoke to Patty about it.

Now watching Patty getting fucked is hot, but she is the slutty one after all. Haley on the other side is still the innocent looking one. I thought I'd never get to watch her fuck, until SAM and her started dating. After I had walked in on them nearly kissing on her 26th birthday, I knew I wanted to see him fuck my sister. It took a while, but when we moved into a house together, I saw my chance. So one night, when Jim was out I made a plan with SAM. I would hide in the closet in their bedroom and watch him fuck my sister. After dinner, we had some wine in the living room. I was the first to leave. I brushed my teeth and when I was in the hall I saw Haley going to the bathroom to brush her teeth. I said good night and then sneaked into her's and SAM's bedroom. He was in there and told me "I have some toys prepared for you. So you will enjoy this night as well."
Me:"Oh I will, trust me.."
I grabbed his dick and caressed it. He moaned silently and I backed off, leaving him semi-erect. I got into position. The closet was spacious for a closet, but I could barely move in there. I removed my sleep shirt, leaving me all naked. Then Haley came in. I could see her nipples through the sleeping shirt. SAM was laying on the bed, already naked. Haley went in front of the closet door, turned to SAM and slowly removed her shirt. I could only see her backside, but just then I realized what an amazing feminine figure Haley has. Haley slowly removed her string and crawled onto the bed. She gave SAM a blowjob and I had a perfect view of her pussy. I could see it getting wetter and wetter. My hand went to my pussy. I slowly rubbed it while my other hand went searching for the toys SAM had hidden for me. Haley climbed onto SAM and kissed him for a while. Then I heard SAM say
S:"Just imagine someone was watching us right now..."
H:"mmhhh just thinking about it turns me on... I would love to show the world that I'm your sex goddess..."
S:"Is there anyone in particular who you want to show? Anyone you want to make jealous?"
H:"I dont know.. maybe Patty?"
S:"Why and who else?"
H:"She always brags about how good she is at fucking. That would show her. hmmm I would love to show Jim... let him know my body only belongs to you... I see him looking at me... and oh! Anna as well. Show her how I can fuck her best friend which she never could!"
S:"Oh you are naughty. But what makes you think she even wanted to fuck me?"
H:"Oh it was just... way before we were together, whenever she would speak of you... she had that look on her face. And the way she talked about you. And how she acted around you. That changed after her wedding I think. And now... I'm the only one who gets your cock..."
With that she let herself sink onto SAM's cock. I could hear the smacking noise as her wet pussy slipped over his dick. I was already fucking myself with the dildo. Haley was riding his cock slowly, moving her hips back and forth. Soon I heard her say "uhh I'm cumming... oh yes.." I had my first orgasm, when her juice was running down his cock. They changed into missionary. SAM did his 0-100 technique. He pulled out completely and then slid it back in all the way. I loved it, immitating it with my dildo. The way the pussy tightens when he pulls out and then the cock forcing its way back in... He was facing me and a few times he looked up and directly at me. I kept immitating his movement and had to hold back so I wouldnt moan just as loud as Haley. Then I thought "Damn I want to go faster... I hope he goes faster now..." Right at that moment he started pounding Haley. I fucked myself with the dildo so hard that I could hear smacking from my pussy.
H:"Uhgggh I'm cumming again... ohh SAM... ohh..." I had my second orgasm just at that time. After she did too, she went on to blow SAM. Meanwhile I tasted my own pussy. I imagined the dildo was SAM's cock and also sucked it off. Soon he blew his load into her mouth. She swallowed it all and kept sucking him. I couldnt believe my eyes. My little innocent sister fucking SAM like that. He said "I love it when you blow my cock until it is hard again.." After five minutes or so, Haley stopped. Meanwhile I had found a buttplug. SAM got some lube. I didnt even know Haley was into anal. But sure enough, Haley got on her knees, laid her head on the bed and offered him her ass. He was facing me again. Slowly he penetrated her. His eyes were locked onto the closet. She grunted in pleasure. I pushed the buttplug into my ass. It was huge. I only had my pussy juice to make it slippery. When I finally had it in, I let out a silent sigh. SAM was fucking my sisters ass. Her moans got louder and louder. SAM kept staring at me and said "Yes, let Anna hear that we're fucking."
Haley grunted and moan and almost screamed in pleasure. I had an orgasm right there and then. I had to lean against the wall so I wouldnt fall. SAM kept fucking Haley... and hard. I never thought Haley could take a pounding like that. I kept fucking myself with the dildo, but before I could cum again, SAM blew his load into Haley's ass and she had another orgasm as well. Then they laid in sleep position, Haley resting her head on SAM's shoulder. SAM threw a thin blanket over both of them and turned off the light. We had to wait until our eyes got used to the darkness. Then SAM signaled me that it was safe to come out.

I opened the closet door, still completely naked and with the buttplug still inside me. When we made the plan I said I was gonna leave as soon as I could, but now I was still horny. I went to SAM's side of the bed and took his hand. I let him feel the buttplug. Then he turned on a small light, which illuminated the room but was not bright so Haley wouldnt wake. Haley's head was still resting on his arm so he couldnt move. I partly removed the blanket, revealing Haley's ass and SAM's now semi-erect dick. I could see the cum dripping out of Haley's asshole... so I spread her cheeks a little and licked it all off, careful not to wake her. Haley's hand went to her ass so I backed off as quickly as possible. But she didnt wake, just smear out the cum on her asshole. I didnt dare to go back to licking it off, but I saw SAM's dick getting harder. So I went over to him and pulled out the buttplug. Then I sat down on his dick, pushing it into my ass. I couldnt move, otherwise the bed would rock to hard. SAM's free hand immediately fingered my pussy. He got in 4 fingers. I couldnt hold back my orgasm. His dick was just too big in my ass and his fingers... I just squirted all over his hand. I got off his dick and kneeled besides the bed to blow him. Then I saw him move his squirt-covered hand to Haley's mouth. He pushed one finger into her mouth and she started sucking it out of reflex. Soon she was sucking on the other fingers as well. His cock was twitching, exploding any second... I went deepthroat and he shot is load directly into my throat. I swallowed it all. I could feel his hot cum running down my throat... I gave him a kiss and finally went to bed.
