caught my sister masturbating, join me she says so i strip and we masturbate together and try to cum together, after a few weeks we started masturbating each other. We were virgins and eventually started touching each other, she has sensitive nipples, we started trying oral sex (she had to teach me what a clit is for) and finally after about six months we decided it was time for us to fuck we went slowly to start with, she told me not to cum because she wanted us to cum together, told her i was nearly there she was disappointed i cum before her but after a couple of months we were able to cum together at last, we shaved each other and sex was even better, after about a year we tried anal, she bought a strap-on so we could experience the same feeling of our asses being filled, we had a wonderful few years till she left home and moved in with her lesbian girlfriend, i was honoured mine was the only cock she has ever had, and yes sometimes i go round and we play together, i fuck them and they fuck me they keep getting bigger strap-ons and i keep asking them to fuck me harder
