My straight 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 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 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 sisters for? I love you sis!!
