After returning home from the dorm, I was aroused by my four sisters' unguarded miniskirt panty shots for the first time in a while. My sisters also noticed that my dick was erect after growing up a bit, making them aroused as well, and they further enticed me with more stimulating poses. Unable to hold back any longer after having my dick grabbed by my sister, she secretly let me have incestuous sex with her, and in the end, all of them fought over my one dick!
