me and my step-sister, Tilly, were playing truth or dare at our sleepover, when the dares really started to take a naughty turn... After daring each other to suck a dildo, I dared Tilly to let me strap on fuck her!! She sucked it before I slid it into her tight pussy in doggy, before she got on top and rode it! She took it so well!! I thought we were finished playing, but she then dared me to get strap on fucked!! I climbed on top and bounced my big ass on her cock, before she bent me over and fucked me hard until she made me cum!! I can't believe me and my step-sister fucked each other!! we definitely can't tell anyone about this... our little secret!!
