My family started hosting a private lodging using the room of my older brother and sister who had left home. One day, my father and mother said they wanted to go on a couple's trip. Today's reservation was for three female guests. I thought I'd be okay with being alone with the grown-up women, but... it was an incredibly sexy, dynamite, super carnivorous mature woman who showed up!! We suddenly had lesbian sex in a threesome, my dick was played with as punishment for peeping, she barged into the bath, and in an instant our house was turned into a carnal desire festival!! ...Mom and Dad, if you don't come home soon, your son's balls will be emptied!!
