Many years before breaking up with my ex we'd been in a sexless relationship..it had got to the stage where she'd even said just go out and have fun it's fine...that's what started me off swinging, dogging meeting off the net for sex..but I never her told her that I did. A couple of things happened after we split and she got her sexual mojo back..in fact by doing what I'd suggested and go fuck someone other than me..as she'd got in to the rut of not doing it with me... One Saturday after seeing my kids, when stayiong over near by, she pulled me to one side and said...I nearly invited a couple over last night for a 4 some..been really horny and wanting to try it but figured you may freak....I simply looked at her and said no wouldn't of freaked at all and it sounded fun..still not admitting to the things I'd been up to when together. She asked if I'd be up for it that night and to stay in the area that extra night...it was no time at all until we were logged on, kids off playing and me posting up for a fun meet that night. We discussed whether it should be another couple or just another guy..she said either, she definately wanted more than one cock though. After getting messages from a couple of people we found ouyrselves chatting to what seemed a really nice guy and a nice couple...so after speaking to both on the phone we decided why not invite them both round if the other couple was cool with that....a quick phone call later and all was arranged. We both showered and got ready..both really nervous, me acting more than I was...8:00pm came and the door range..it was the guy...a younger guy late 20's fairly thin but not bad looking...we were just saying our hello's and pouring wine when the door went again...a couple more our own age, mid 30's..she short but even through a coat you could tell she had a good body..him more like me..well built, good sized shoulders.. Coats off wine poured and we all chatted about experiences and fantasies..me not admitting anything still....after 20 minutes or so the guy from the couple stood up and said ok...we all up fun then and if so where...we all smiled and said right here in the front room. In what seemed like seconds...I was kissing his wife who was now just in a basque and stockings, my fingers rubbing her pussy lips...my ex was totally naked with one guy sucker her small tits but large nipples and the other knelt down rubbing her pussy... I looked up from licking the womans wet shaved pussy to see my ex on all fours..cock deep in her mouth and the womans husband behind her fucking her really hard and deep...telling her that she had a lovely pussy and felt really good...then the younger guy said god I can't hold it I'm going to cum..the ex stopped sucking him just long rnough to tell him that was fine and to pump it all in to her mouth... I was so horny..I was now fucking the other guys wife as she pulled hard on her nipples..watching my ex swallow this young guys spunk as this womans husband asked if it was alright to fill my ex's pussy to which she simply nodded frantically. The young guy was hard again in what seemed seconds as was soon taking the position of the other fucking my ex's now soaked pussy...whilst she took time sucking the older guy back to hardness. It wasn'y long before I cum inside the guy's wife her moaning loudly as she tugged on her own clit....the young guy was already cumming again, adding to the cum already inside her..then the wife moved across...my ex now on her back with the young guy licking her clit and the older guy's hardened cock in her mouth... The wife looked atme and I nodded..in no time she was down on my ex's pussy expertly licking it and lapping at the cum inside..my ex looked up and said who is doing that that feels so fantastic...we all just smiled... After a rest it wasn't long before I was fucking my ex...two cocks near her mouth ready for more cum as I licked the other womans pussy as she srood next to me... Several cums later we were all shattered..chatted for a bit more..drank more wine and they left for the evening...knackered we went to bed. In the morning I fucked my ex so hard and long remembering the night before....that was the last time we ever fucked.
