Behind a door listening to my wife take a monster.

It had been a week since the night that I sat in my friend Rob's living room listing to my wife April getting her brains fucked out by Rob's massive cock. After I finished fucking her I put my pants back on and walked back into the living room where Rob was sitting having a beer he looked at me as I sat down smiled and said "Man your wife is fucking amazing" I told him thanks and he quickly shot back with "No thank you man". I laughed and got up as April came out of the bedroom sweating and walking slowly after Rob fucked her in the ass. She smiled and said "We better get going, its late" We got to the door when Rob gave my wife a hug and a kiss on the cheek and said "We should do this again" as he had his hands on her waist, She smiled and nodded. We got in the car and I could tell she was exhausted. She didn't say much the ride home but a couple days later she asked me if I bothered me that she had sex with Rob. I laughed and told her no, I asked her if it bothered her. "No" she said "It was amazing". That was about the conversation about it and we went on with our lives. Rob called me a couple days later and asked us if we wanted to come by and have another BBQ. I told him that I would have to check with April when he told me that she was the one that called Janet and asked if it was OK we stop over. I told him it was a plan and that we would be over later tonight. I was on the couch waiting for April to finish getting ready when she walked out of the bedroom wearing a short black leather skirt and a tight white shirt and her high heel shoes. She looked amazingly sexy and I could tell Rob was going to be all over her and that maybe she was dressed more for him than me. I was turned on the whole ride there knowing that Rob and her were probably going to fuck again. We got there and Janet greeted us at the door and took my wife by the hand and walked her into the house, she told me that Rob was in the back yard grilling. I got back there and he was sitting on a lawn chair next to the grill with a beer in his hand. "What's up man" he said as he stood up to shake my hand. He asked me how I was doing and of course if April was here. I told him she was inside with Janet. He smiled and said "Are you OK with what happened last time?" I told him it was my idea that she have sex with another guy and that it was something I wanted to do. He leaned over and said "Don't tell my wife but April was the best sex I ever had before" I smiled and said your secrets safe with me. We went inside and ate than all went and sat in the living room. We sat there for awhile talking and having some drinks when Rob leaned over on the couch and whispered something into Janet's ear. She smiled and gave him a kiss. She stood up and walked into the bedroom and shut the door. I was sitting on the other couch with my arm around my wife when Rob asked her how she was doing and other questions when the bedroom door opened and Janet walked out wearing some lingerie. She walked over to the couch where me and April were. April said "Damm girl you look sexy" She said thanks bent down and planted a kiss on my wife. She whispered something into her ear than Janet grabbed me by the hand and took me into the bedroom and shut the door. She turned to me and we started making out. She sat on the edge of the bed and said "Rob fucked your wife, now you get to fuck his" I smiled as I took my cloths off wondering what Rob and April were doing in the other room. She took my cock and put it into her mouth. As she sucked me I tried to listen for noises in the other room but heard nothing. She sucked my cock until I laid her down and took her lingerie off. I slid my cock into her as she moaned. As I fucked her my mind was out in the living room with my wife and Rob. Janet screamed as she came on my cock and I snapped out of it. I fucked her as hard as I could knowing that Rob was listening. I flipped her over and fucked her from behind while I fingered her asshole. She moaned and screamed until she came again. I pulled my cock out and pushed her flat on the bed on her stomach and began easing my cock into her tiny ass. I shoved it in as she let out a scream, I started pounding her hard right away instead of going slow but she seemed to like it. She kept screaming "Fuck my ass" over and over. I fucked her ass as hard and as fast as I could until I yelled "I'm going to cum in your ass" She let out a "Ya" between her screams. I thrusted as deep as I could until I let out a grunt and shot my cum into her ass as her tiny body shook. She laid there panting as I put my pants back on. She sat up and said "That was amazing". We opened the door to the living room and saw Rob on the couch with his head back and my wife on her knees again sucking his cock. "Sounds like you had fun" he said as Janet laughed. Janet bit her lip and went and sat next to Rob and began kissing him as my wife sucked his cock. I sat back down on the other couch and watched. My wife didn't look over to me just kept sucking him as Janet made out with her husband. Janet reached down and put her hand on April's head and began pushing it down on her husbands cock. She looked over to me and said "Do you like watching your wife suck his cock?" I smirked and said yeah. Janet kept shoving her head on his cock only to stop her and start kissing her and than shoving her head back down. Janet pulled off her cloths and sat right next to Rob opening her legs and rubbing her pussy. My wife stopped leaned over and began eating Janet's pussy. My cock got hard again watching my wife eating pussy as Rob sat there stroking his cock. She went back and forth eating Janet out and sucking Rob's cock until Rob stood up and grabbed my wife and again walked her into the bedroom. Janet came back over to me and began sucking my cock again. I heard my wife and Rob laughing in the bedroom and than silence. I was watching Janet suck me when I heard my wife let out a scream and than start moaning very loudly. I heard the bed squeaking and Rob say "You like that cock bitch?" She was moaning but was able to let out a "Yes". I could hear his skin slapping against hers faster and faster until she screamed so loud Janet stopped and looked at me smiled and said "I think she loves that cock". I heard her yelling "I'm cumming, I'm cumming" as she let out another scream and than Rob saying "Cum on that cock". I heard her gagging and Rob say "Taste that pussy baby" Janet got up and kissed me and turned and walked into the bedroom and shut the door. I heard Janet say "Take that cock girl". My wife came again and again until I heard Janet say "Do you want him to fuck your ass?" My wife whimpered yes as there was silence and than a murderous scream. Janet said "Yeah, fuck her ass baby" as my wife was screaming louder and louder. I heard Rob grunting loudly until Janet said 'Cum on her face" The bedroom door opened and Rob walked out wearing only boxers and walked into the kitchen and grabbed a beer. I walked over to the bedroom and saw my wife was laying on the bed with her legs open panting heavily as Janet was licking the cum off of her face. I walked in and dropped my pants and began fucking my wife's almost lifeless body as Janet continued to lick all of the cum off of her face. Almost as Janet finished I pulled my cock out and shot my load onto my wife's face as Janet began licking it off. I walked into the living room as I fastened my pants as Rob smiled and said "I could never get tired of fucking her man". I smiled and said I believe it. My wife and I went home that night and she was so horny we fucked as soon as we got home but I could tell she was still thinking of Rob as we did it. The next day my wife was at work and I was at home with the day off and thought I would swing by Rob's to see what he was up too. When I got there I noticed that April's car was out front. I walked up to the window that looked into the living room and saw my wife bent over the couch arm as Rob fucked her from behind. I was stunned. She knew I was OK with it but it was always something that happened when I was around. Later when she got home her legs were shaking and she was sweating. Before I could ask her about why she was at Robs she cut me off with "I think we should get divorce" She is dating Rob now and I am seeing Janet.
