I'm very adventurous and normally never say no to new experiences and the first time my step-son asked me if I had sex with him I said yes, why not? His Dad even likes to watch me having sex with other guys, so why not with his son? No need to say I really liked it and my head didn't stop thinking about doing the same but with my son. It a was bit tricky but I knew that my step-son told him we had sex he would like to try it too, and I wasn't mistaken...
