I Know It Is Wrong

There is an 18 year old girl who works with my wife . She is plump with a pretty face . The first time i saw her i wanted her . I knew there was no chance . Then one weekend we were at a party and she was there . Everyone was dancing . I danced with a few different women . My wife was dancing with different guys . Sometimes we danced with each other . All the guys were dancing with fit women . The girl was not getting any attention . My wife danced with her a few times . My wife asked me to dance with the girl and be nice to her . Later that night , when we had all been drinking . It was everyone dancing with each other . Not with their wives or girlfriends . Couples were dancing and kissing . This always happened at these parties . The married ones like us . Did it , but it did not lead to anyone having sex . I was dancing with the girl . We were kissing . Holding her and kissing her gave me an erection . I asked if she wanted to go outside to get some fresh air . She followed me outside . It was now about 1-00am . Everywhere was deserted . I took her to a dark area behind some buildings . Kissing her , i put my hand up her dress and touched her pussy . She let me do it . I pulled her panties down so i could finger her . She was kissing me and using her tongue . She opened the front of my trousers and took my erect cock out . I turned her round . Trying to fuck her from the back . She pushed my cock away saying no . Then she was wanking me . She made me cum . I rubbed her pussy making her cum . We stood kissing for a long time . Then we went back to the party . We had not been missed . I was feeling frustrated that she had not let me fuck her . The party ended and everyone went home . My wife would talk about what they had done at work . Her and the girl going out for lunch and talking . The girl sometimes askd if i was ok . About 6 weeks later . (This is in England) I was dropping my wife off on Saturday to meet her mother so that they could get on a bus . Taking them to the city centre . They did this every Saturday . Spending the day going round the shops , going to cafes . Then going to their favourite restaurant for a meal before returning home . My wife was never home before 6-00pm . Driving home , i saw the girl at a bus stop . I stopped to say hello and ask her where she was going . She was going in to the city . She did it most weeks . I offered her a lift . In the car we were talking . She told me she did not really enjoy going in to the city centre . But going there and visiting a coffee shop . Was better than sitting at home watching tv . I asked her if she wanted to come home with me for a coffee . Not mentioning that my wife was out . When she saw that my wife was out . I told her that it would not be long before she came home . I made the coffee and we sat on the settee , talking . Being with her was making me feel horny . I made a move to kiss her . She let me do it . Even putting her arms round me . For a time we sat kissing . She was using her tongue . This gave me an erection . I put my hand up her dress . Touching her pussy through her panties . She opened her legs for me . I pulled her panties to one side . Fingering her wet pussy . Now i told her that my wife would not be back until late . I asked her to come to the bedroom . In the bedroom i was kissing her and fingering her pussy . I unzipped the back of her dress and took it off . I unfastened her bra and took her panties off . I loved her plump body , big tits , and hairy pussy . I told her to lay on the bed . I undressed . I got on the bed with her . Kissing her and feeling her boobs . She was holding me erection . I got on my knees . Kissing her . Then moving down to kiss and suck her tits . I kissed and licked my way down her fat stomach . Enjoying every second . When i got down to her pussy she spread her legs apart . I buried my face in her wet pussy . Licking and sucking her clitoris . Making her cum . Then i got between her legs to fuck her . This time she did not stop me . She said she was sorry she had stopped me the last time . She was scared of getting pregnant . She had wanted to be fucked . So she had gone on the pill . This was her first time . All this made me even more excited . Too excited . Almost as soon as i started to fuck her i was cumming . We stayed on the bed . I licked her a few more times . Making her cum . Then when i was ready i fucked her . This time it took me longer to cum . We got dressed and i gave her a lift home . In the car i asked if i could see her again . Her answer was every Saturday . After dropping off my wife . I drove round to where she lived to pick her up . Then we spent the day having sex . Before it was time for my wife to come home . I would give the girl a lift home . That was my Saturdays . For the next 2 years . The it stopped when she got a boyfriend . Now i sometimes watch plump porn on Saturday and wank a few times .
