While my live-in girlfriend was away, my aunt and her sister came to stay over. They were too defenseless, and unconsciously tempted me, making me fully erect and unable to calm down. I secretly set up a camera to record them, but got caught, and my aunt unexpectedly requested a filming session! 'Which one feels better?' they asked alternately, and I couldn't decide at all. My aunt's incredibly pleasurable vagina made me ejaculate until I ran out of sperm, leaving me exhausted. This work is packed with everyday thrills and excitement, and it leaves a lasting impression after viewing, making it a masterpiece.
