My much younger step-brother was staying at mine and we were hanging out playing video games. I got bored so I went to shower and get changed for bed. I caught him perving on me in the shower and he admitted to me that he had wanked over my porn, but he was still a virgin! I was shocked, but also so turned on! I told him it was time to become a man and who better to pop his cherry than his experienced step-sister. I introduced him to so much how to play with pussy, feet, tits and, of course, lots and lots of sucking and fucking! We got completely carried away and night turned into day before he eventually came over his favourite part of his horny, step-sister - my massive tits!!!!
