My straight step-sister shows me her new toy she got to play with her man in bed! I get curious and let her test it on me. She knows I'm a lesbian and hates dick!! But something about my step-sister using it on me.. it felt natural! She fucks me so good that I end up pissing all over the place!! The only way for my step-sister to get even is allowing her to piss all over my big natural tits! She gives me my FIRST EVER golden shower! What more are step-sisters for? I love you sis!!
