Seduced By A 13 Year Old Girl

When my wife was still my girlfriend and had started to go to work . For convenience she lived with her grandparents . They lived a mile from me . My girlfriends parents lived 12 miles away . Every Saturday we went to her parents house . She went in to the city with her mum . They would spend all day looking round the shops and going to cafés . Her dad was working overtime for extra money . From 6 to 6 . I stayed at the house with her 13 year old sister . I was 17 . For a long time all we did was watch Saturday TV . Her sister was always downstairs and dressed when we arrived . Then one week she was not there . My girlfriend asked her mum where she was . She was still in bed . She was tired . When they had left to get on the bus . She came downstairs . She was still in her nightclothes . Her shorty pyjamas and a matching top . She said hello to me , and have they gone . I was sitting on the couch and she sat in an arm chair . We watche tv . She was a nice looking blond . At first she was sitting on the chair in the normal way . Then she put one leg over each arm . When she did this i could see up the leg of shorty bottoms . I could see her pussy . She stayed like that for about 10 minutes . Then she pulled the bottoms to one side exposing her pussy . I was looking at it . She was smiling at me . Then she lifted her top . Showing me her tits . They were small but nice . She let her top fall to cover them . Still looking directly at me . She was rubbing her pussy . I could see it getting wet . She took her bottoms off and got back on the chair with her legs over the arms . I know she could see the bulge of my erection . She rubbed her wet pussy and pushed 2 fingers in it . When she pulled them out i could see them wet with pussy juice . Then she sucked them . When she did that . I could not control myself any longer . I got down on my knees licking her pussy . I licked her and made her cum . I stood up and took my trousers off . I got between her legs to fuck her . In my excitement i never thought about making her pregnant . I was cumming in her pussy . After we got dressed i asked her if she had started her periods . I was relieved when she told me her periods had not started . Now on Saturdays we both undressed and got in her bed to have sex . When she told me her periods had started . I bought condoms to fuck her . After me and my girlfriend were married . We still went to her mothers and they wen shopping . She was now 17 . She still let me fuck her . Me and my wife lived in an apartment . Some weekends her sister came to stay . When my wife met her mother . I had sex with her sister . On a Sunday morning my wife liked to visit her friend who lived 2 floors below us . In the block facing ours . We could see her door from our apartment . When we saw her going in . I took of my trousers and her sister took of her panties . She sat on the couch letting me lick her pussy . Making her cum . From the couch she could see if my wife was leaving her friends apartment . I always fucked her with her leaning on the back of the couch with her dress lifted up . So that i could see the door . She scared me one week when she told us she was pregnant . I knew i had been careful but it made me wonder if i had made a mistake . Then she told us about her boyfriend . It was his baby . They had not been taking precautions . They got married .
