My Childsitters

I was not really a child . I was 12 . But my parents did not want to leave me alone at home over the 3 weeks school Christmas holidays . They wanted someone to look after me . Two of my girl cousins were home from university for the holidays . One was 20 and the other 18 . My parents offered to pay them to look after me . It was cold snowy weather outside . So we did not go outside . At first we played board games . But we were bored . My parents were at work all day . My cousins were sisters . After about 2 days . The eldest asked her sister . Why don't we teach him about sex . I sat there wondering how they were going to teach me . They took hold of me and pulled me on to the carpet . Then they held me down while they undressed me . I lay on my back on the carpet . Not knowing what to expect . My limp penis was laying on my stomach . They undressed . Watching them gave me am erection . The eldest kissed my penis . She rubbed her vagina . She pushed her fingers in to her vagina . When she pulled them out i could see that they were wet . She croched over me facing me . Sliding her vagina on my penis . She was riding me and her sister was touching my balls . My first experience of feeling my penis in a vagina . It only took a few minutes for me to cum . Later when they could give me another erection . The youngest sister slid on to my penis . Two fucks and orgasms in one day . Every day they told me to do things . They taught me to finger them and have oral sex . They showed me where to find the clit and how they liked me to suck it to make them cum . I was enjoying my sex lessons . Over that holiday i learned how to satisfy a girl . They taught me their favourite positions . They had lesbian sex with me watching . They gave me blowjobs . In a short time i went from a sexual virgin . To experienced . One thing that they kept telling me was that they were on the pill . If i had sex with girls i had to pull out to cum .
