Mark arrived and Jess let him in greeting him with a big hug and kiss. We walked to the taxi rank, Jess had a nice summer dress on, no bra as her boobs are still very firm, both Mark and I with jeans and shirts on. We went to our favourite sea food restaurant and as usual the food was excellent and then on to a bar. The drinks mainly mojito's were flowing well and the talk started to turn a bit suggestive it was Mark who first mentioned our swinging activities , he said I bet Jess gets plenty of attention at parties and clubs which made Jess laugh. It's funny how the drink makes you more relaxed and you say things that you would never dream of saying when sober. Mark shocked both of us when he said he was bi and his last relationship was with another guy, Jess looked at me and smiled then Mark said I hope you are not offended with me being bi. Before I could say anything Jess said no we are not offended at all infact we are both bi and we have both had same sex fun. I could see that Mark was getting a bit excited now asking what I felt knowing or watching Jess have sex with other guys or girls, I told him it really turned me on and after Jess and I had the most amazing sex and as long as we are both happy we cannot see any harm in enjoying our selves. Mark then asked me if I have sex with other guys , Jess butted in and answered for me and said yes and as with Billy knowing I have sex with other people and it makes him all horny its the same for me I like see two guys enjoying each other and that said Jess said it is now 2 am I think it's time to go and she said to Mark she would love him to come back with us, although we all had a lot to drink Mark could not say yes quick enough . We got a cab, Mark jumped in the back with Jess and we soon arrived back at our apartment. Once inside Mark asked if he could kiss Jess as a thank you go for it I said, the kiss turned into a full on snog when they broke apart you could see both of them were horny for each other so I said Jess why don't you take Mark into the bed room I will get us some drinks, it was a very warm night but we have a/c in all the rooms. On entering the bed room what sight greeted me there was Jess and Mark both naked, Mark is about 5ft9ins and a well toned body with his tan he looks more like a local, Jess was on her knees with Marks cock well down her throat, from what I could see Mark was about average size in the cock department but later I could see he had a very wide girth. So I removed my cloths and joined them, Mark took hold of my cock and slowly started to wank my now rock hard cock, Jess released Marks cock and we all got on the bed with Mark parting Jess's legs and started to explore Jess's pussy, I moved so I could put my cock into Jess's mouth now I have had quite a few bj's from both male and female but no one comes close to Jess she some how manages to open her throat and your cock feels as if it is in a pussy. Mark certinally seemed to know what he was doing from the way Jess was pulling his head into her pussy, we all changed around and it Marks turn to find out how good Jess was at giving bj's. He did not last long and was soon telling Jess he was going to come and true to form Jess held him so she had all his cum down her throat, Jess was right when she said he came a lot he seemed to just keep pumping his cum down Jess's throat so much so Jess had to push him back and afterwards she said she thought she was going to drown in his cum which caused Mark and me to laugh. We all had a drink but what amazed me was Mark never lost his erection at all, Mark moved over and took my cock into his mouth I could tell this was not his first bj Jess was sat watching slowly playing with her pussy, I had to ask Mark to stop before I cum so with that Jess said she needed a cock in her pussy of course being the gentleman I am (lol) I said guest first, Mark did not need asking twice, I was impressed with Marks love making skills I thought being a young guy he would get his cock in as soon as he could and just bang away till he cum but I was mistaken he took his time entering Jess putting a little in then with drawing and then back in a bit more until he was fully in, Jess had now wrapped her legs around Marks back and he was giving her a very gentle fucking until Jess said fuck me harder make me cum fill my pussy with all that cum, Mark put her legs over his shoulders and started to really fuck her she was asking him to not stop but fuck her harder all words I have had the pleasure of hearing before, Jess was now very vocal when Mark said he was about to cum and where did Jess want it Jess said in my married cunt a word I have never heard her say before, Mark made one last thrust and I could see his arse cheeks clenched together as he pumped his young cum into her willing pussy, as Mark was pumping his cum into Jess her own orgasam took over she shouted at Mark to leave his cock in her pussy, they stayed coupled together for what seemed ages then Mark with drew his cock and it was still quite erect O to be young again. Marks cum was like a torrent running from Jess's pussy and so tempting, I was soon between her legs and enjoying Marks cum but itwas so horny I entered Jess and with all that cum still in her it did not feel it's normal tightness, I still did not last very long and added my cum to Marks when I withdrew Mark took my soft cock and cleaned it before doing the same to Jess's pussy. We rested for a while before Mark was ready to go again in the end I went to the other bedroom as I was worn out and left Mark and Jess to fuck the rest of the night away, in the morning when I got up I could hear Jess getting a final fucking before Mark had to shower and leave for work. Jess said Mark had fucked her several times during the night and at no time did Mark fully lose his erection, one thing Mark said to Jess he would like to have full sex with me. Well Mark came around a couple of nights later but it followed the same pattern as before with oral being the only mm contact, we are back in the UK now but going back to Spain on the 8th October By then Mark will have gone so some other lucky young guy might be able to enjoy the charms of Jess and me, if that happens we will let you guys know and if any young guys fancy a break in Spain let us know. Hope you have enjoyed our encounter with Mark it is a totally true account of what happened sorry it was so long but Jess wanted the full account told. Billy and Jess xx
