GDHH-051 Sis! Where are you pissing!? My drunk sister came home and is pissing in the most ridiculous place!? No matter how much I warn her, she won't listen. My drunk sister just moons me! Pissing with her vagina fully exposed! Seeing that overly erotic

My older sister returns home drunk as a skunk. Despite my concern for her, she suddenly pulls down her panties... and starts pissing—right there in the hallway! In the living room! Even in my room! I'm so shocked that I'm speechless! And no matter how much I try to warn her, she won't listen! But seeing my sister with her ass out, pussy wide open, and pissing right in front of me, of course, I get a full hard-on! Did my sister get turned on by seeing her little brother's excited state? Or was she just drunk? She reaches out and grabs my erection, and we end up fucking in an incestuous taboo, coming over and over!
