Once the videos of Claire and Sarah had been swapped and viewed Chris and myself wanted to keep the momentum going, and it was quite clear that we wanted fuck each others wives. I had touched on the subject of things going further with Claire and she said that as long the things we did remained just between us as couples then she would be willing to try a swap. I told Chris and he in turn spoke to Sarah who was more than willing to keep things going. We arranged to go bowling then back to Chris and Sarah's as they had sent their kids to Sarah's parents for the night. I sent Chris a text without Claire knowing before we left asking him to have Sarah's dildo at the ready as I wanted to see it in Claire at some point that night. He replied saying he'd already taken care of things and that Sarah wanted to use it on Claire herself. This was an exciting twist as seeing Sarah use it on Claire would be a huge turn on. We picked Chris and Sarah up and had a nice evening bowling and dropping little hints as to what would be happening later that night. I remember as Claire was bending down lining up a shot, I leaned over to Chris and said "just think, in a couple of hours she's going to be stark naked on her knees sucking your cock" Chris was smiling ear to ear and said "she's going to be doing more than that tonight" Sarah then sat down between us and said "what are you two pervs talking about?" I said "oh, just saying how good you and Claire will look later in all your naked glory" Sarah cracked a smile and said "so you're not looking forward to it much then" with that she got up to take her shot. Claire then sat down and could see something was up as were still smiling from Sarah's last comment. Claire then asked what time we were leaving. Soon I said you've got a busy night ahead, at which point Claire stood up and sat on Chris's lap. Sarah then returned from taking her shot saw Claire on Chris's lap and came and sat on my lap. We finished the game and made a quick exit we were keen to get the wives naked and naughty. We were soon back at Chris and Sarah's and went straight to the front room were Chris had laid out some duvets and pillows on the floor. Sarah and Claire opened a bottle of wine and had a glass and then dissappeared upstairs. A few minutes later after alot of giggling and movement upstairs Sarah and Claire walked down the stairs in just knickers and bra's. I had a massive hard on and I'm sure Chris was as hard as a rock as well. "Well boys", said Claire, "where do you want us" In an instant Chris and myself were naked and Sarah moved towards me, and Claire joined Chris on the sofa. I got up from the arm chair, pulled Sarah in close, turned her round and ran my hands all over her body. I groped and squeezed her bra covered tits before moving down and putting my hands in her knickers and getting my first feel of my best friends wifes pussy and arse. Sarah was reaching back stroking my cock so I then ran my fingers inbetween her cunt lips and could feel how wet Sarah was. I then yanked Sarah's bra off and pulled down her knickers. At last she was totally naked in front of me and I was going to make sure I used all her holes before the night was out. I had a brief glimpse over at Chris and Claire, Chris had already got Claire naked and had his hands all over her body. Claire was enjoying things so I got back to concentrating on Sarah. I sat on the arm chair and Sarah got on her knees and with a quick wink took my cock in her mouth. God it was erotic, at last Sarah was sucking my cock. I was feeling her tits up as she sucked and got a good little pull on her perky nipples. Her head was bobbing up and down so I put one hand on her head and started to see if she would take more and more until she was deep throating me. Sarah knew what I wanted and made a couple of deep thrusts taking my cock all the way in before coming back up and asking "was that good?" Fucking amazing I said and back down she went for another deep suck. I again looked over and Claire's head was going up and down and Chris's face was a picture. Claire came up and spat on Chris's cock and started licking his shaft down to his ball sack. "Dirty slut" I thought. After a good cock sucking session Chris made the first move and repositioned Claire on the sofa with her legs open and started to lick her pussy. Claires breathing immediately got quicker and was obviously loving having Chris between her legs. I decided to do Sarah differently so I positioned her on the arm chair on her knees making sure her legs were apart and started to lick her pussy from behind. Sarah tasted amazing and I was soon rimming her arsehole and sucking on her cunt lips. Sarah was also breathing harder now and was very aroused. I put one hand in between her legs and gave her nipples a flick which made her body give a little jolt but she didn't complain so I did it again. "I asked Sarah if she liked me licking her arse to which she replied "I fucking love it, keep going" Her cunt lips were even better than on the video and I had licked and sucked them so they were now nice and exposed. I spread her arse as wide open as I could and put my tongue as far in as I could and Sarah was loving it. Claire was now sat upright on the sofa with Chris stood directly in front of her with one hand on her head and one hand under her chin, she had her hands on his arse cheeks and Chris was fucking my wifes mouth quite hard and fast. Chris was giving Claire instruction " suck that cock slut, take it all" I couldn't hear any gagging so Claire was managing quite well and giving Chris the suck job of his life. I still had Sarah on the arm chair arse up so I grabbed my iphone and asked if I could get a quick shot. Sarah said ok so I asked her to spread her arse as wide as she could and took a few pics. Chris looked over and said "good idea, I forgot about taking some pics". With that Chris got his phone and told Claire to get in the same position as Sarah. Claire did as she was told and got on all fours and spread her arse open for Chris's pics. Chris took a few and then put the phone down. Claire stayed on all fours and Chris was behind her and eased 2 fingers straight into Claire's wet pussy. Claire let out a moan and was clearly enjoying being finger fucked. Sarah was now watching with me as Chris slowly got Claire's pussy making that lovely squelchy noise she made when she's wet. Sarah said "that looks so nice" so I positioned Sarah on all fours next to Claire and started to finger fuck her pussy and soon enough her cunt was making the same squelchy noise as Claires wet hole. Both girls were now moaning with pleasure and were quite lost in the moment. Chris leaned closer to me and said "do you think Claire would let me finger her arse?" I thought lets find out. "Claire babes"....."oh, oh what?" "Can Chris finger your arse?" Sarah then turned her head towards Claire and said "go on, you'll love it" I'd fingered Claires arse many times myself so I knew she would let him. "ok" she said. "Me too" said Sarah. Great I thought, There arses are now fair game. It was then that I also remembered that in the video Chris spanked Sarah quite hard. "you girls also up for a spanking?" I asked. Sarah answered that she was "ready when you are", "what about you Claire?", "ok ,but not too hard for me" with that I gave Sarah a mighty smack on her left arse cheek and then on her right. Her body jolted but not a whisper from her. I then gave her another and another and another, spanking the slut making her arse cheeks bright red. Chris then gave Claire her first smack on her arse but not as hard as I had spanked Sarah. Claire received about a dozen smacks after which her arse cheeks we also red. With a good spanking administered Chris fetched the lube and put a little on the girls arseholes. I eased a finger into Sarah's tight arsehole while Chris being a bit cheeky put 2 into Claire. Claire gave a sharp intake of breath but didn't complain and soon Chris had 2 fingers in my wifes arse and was slowly easing in and out. I gave Sarah's arse the same attention with one finger and I could see she was loving it. Sarah was rubbing her pussy from underneath and Claire was told to do the same. It was then that I decided to fuck Sarah's pussy. I removed my fingers, parted her legs a bit more and started to rub my cock over her cunt lips. "fuck me" she said "fuck my pussy" I then pushed my cock all the way in and she let out a moan of pleasure. Chris then said "let's spit roast her", "fucking yea" I said. With that Chris told Claire to "watch this as you're next". Chris lifted Sarah's head up and she took him in her mouth. "Claire watched and was transfixed as Sarah took 2 cocks..........part 2 cumming soon. Would love to hear your comments.
