Sis Slurping Pussy Fucking

I had an argument with my sis and came out on top when she begged me to not tell mom and dad and I had her suck my dick for it. Damn, this fucking slut loved giving working her mouth up and down my big black cock and obviously we didn't stop on that. Man, I could never imagine myself fucking my 18 y.o. sister with no rubber, but that warm slurping pussy felt so good I know I'm gonna make it a regular affair. Fucking yeah!
